Many might not know it but the failure within electrical cabinets is mainly caused by the overheating of costly equipment as a result of failure to provide active ventilation. It would be far more costly to replace a certain equipment, pay for more labor and incur work interruption as compared to the cost of installing a proficient fan unit to ventilate electrical enclosure.

Charlotte, NC -- (SBWIRE) -- 07/25/2014 -- There are four types of cooling electronic or electrical equipment housed in enclosures and cabinets / cabinet cooler. They are thermoelectric air conditioners, compressor-based air conditioners, vortex coolers, and air-to-air heat exchangers or heat pipes.

When components are subjected to aggressive, inhospitable environments, computers and other susceptible electronic devices are used. Electronic equipment are being damaged by high temperatures, humid, corrosive atmospheres, and contaminant-laden air. For those who can afford, the costs and ease related to repairs, downtime, and data loss as a result of insufficient or lack of protection, indeed experience the investment in technology.

There are two sources of unwanted heat. They are internal heat sources and external heat sources. Both cause the internal temperature of an enclosure to surpass the recommended electronic and / or electrical ratings of manufacturers. Internal heat sources are those coming from AC drives or inverters, battery back-up systems, communication gear, PLC systems, power supplies, routers and switches, servers, and transformers. External heat sources are those coming from blast furnaces and foundries, engine rooms, food processing factories, industrial ovens, hot climates, manufacturing plants, outdoor solar heat gain, and uninsulated and / or non-air conditioned buildings.

Based on a research on cooling systems for cabinet enclosure cooling options, below are the features and comparison of the four cooling electronics:

Design. Thermoelectronic air conditioners are in solid state; compressor-based air conditioners are electro-mechanical; vortex coolers are pneumatic; while air-to-air heat exchangers are liquid vapor cycle.

Reliability. Thermoelectronic air conditioners have heat pump more than 150,000 hours MTBF; compressor-based air conditioners have compressor less than 100,000 hours MTBF with limited fan; vortex coolers relies on plant air compressor with less than 150,000 hours MTBF; while air-to-air heat exchangers have more than 300,000 hours MTBF with limited fan.

Maintenance. Thermoelectronic air conditioners virtually do not require maintenance other than the fans; compressor-based air conditioners require cleaning, changing of filters and recharging of refrigerant; vortex coolers require filters, separators need to be changed, and they must be drained on a regular basis; while air-to-air heat exchangers virtually do not require maintenance other than the fans.

Size and Weight. Thermoelectronic air conditioners are moderate in size and weight; compressor-based air conditioners are moderate to heavy size and weigh; vortex coolers are small size and lightweight, separators need to be changed, and they must be drained on a regular basis; while air-to-air heat exchangers are moderate in size and weight.

Environmentally Friendly. Of the four, thermoelectronic air conditioners and air-to-air heat exchangers are considered as environmentally friendly, while compressor-based air conditioners uses CFCs, HCFC, or other chemicals and oils, and vortex coolers require high energy.

Ability to Cool Below Ambient. Only air-to-air heat exchangers are not capable of cooling below ambient.

Temperature Control and Stability. Thermoelectronic air conditioners have precise bipolar control (<+/-0.5 C); compressor-based air conditioners have inefficient resistive control (>+/-1.0 C); vortex coolers and air-to-air heat exchangers are both used to limit temperature rise.

Heating Options. Both thermoelectronic and compressor-based air conditioners have heating options while the rest do not have.

Orientation. Thermoelectronic and vortex coolers can be used in any orientation; compressor-based air conditioners must remain in fixed orientation (horizontal or vertical; while air-to-air heat exchangers can be used horizontally or vertically.

Portability. Thermoelectronic air conditioners have standard units that operate in motion; compressor-based air conditioners have special unit required; vortex coolers require a portable air compressor of suitable capacity; while air-to-air heat exchangers have heat exchangers that use heat pipes and lose cooling ability if not oriented vertically.

Power. Thermoelectronic air conditioners and air-to-air heat exchangers have wide range of AC and DC voltages; compressor-based air conditioners are primarily AC-powered; while vortex coolers are based on plant air compressor.

Noise and Vibration. Thermoelectronic air conditioners and air-to-air heat exchangers produce light noise and vibration from fans; compressor-based air conditioners produce some noise and vibration from compressor and fans; while vortex coolers have noisy air compressor.

Initial Cost. There would be moderate costs for both thermoelectronic and compressor-based air conditioners, low costs for vortex coolers if there is an already available appropriately-sized compressor, and technically low costs for air-to-air heat exchangers.

Operating and Maintenance Costs. Air-to-air heat exchangers have the lowest costs in terms of operating and maintenance as compared to the other three, followed by thermoelectronic air conditioners (low costs), compressor-based air conditioners (moderate), and vortex coolers (very high).

Based on the comparison given above, thermoelectric air conditioners provide the most significant benefits as compared to the other alternative technologies. The use ofof it offers solutions to the intricate cooling problems where, in an unforgiving environment, a low to moderate heat must be handled. STREAMTEK™ Corp provides this kind of technology in the form of a high-performance, competitively priced Cabinet Panel Cooler that incorporates STREAMTEK's™ reliable Vortex Tube to purge as it cools electronic and electrical enclosures. The filtered air that enters your electronic control panel cabinets is up to 45°F colder than the compressed air supply.

Air knife becomes a break in tree care. For the first time, man can now work with the part of the tree that’s buried underneath – where 90% of the tree’s health problems arise.

Charlotte, NC -- (SBWIRE) -- 06/09/2014 -- Air knives are usually used in manufacturing or as the initial step in a recursive recycling process to segregate lighter or smaller particles from other component. This is far from being environmental.

In tree care, air knife is a tool that makes use of compressed air to safely dig the soil without damaging the roots. This technology was first developed by the US Military to get rid of land mines. The air knife transforms compressed air from a portable air compressor to a supersonic jet-stream through the use of its specially engineered nozzle. The ground is penetrated by this finely concentrated stream of air to a depth of nearly 30cm and can be aimed to crumble and shoot the tool as fast as the operator maneuver the tool. The fact that tree roots, rocks and pipelines are not porous, soil can be quickly dug – without damaging these structures.

On a study which involves the excavation of 5,000 root collars, specialists found out that 99% of the trees need serious corrective work. Specialists found that there are tons of girdling roots that are planted too deep. This causes roots to grow abnormally and over time, usually within 10 – 20 years these roots surround the trunk as the tree grows in diameter. These girdling roots can be easily detected by an air knife making it easy to get rid of.

Aside from the girdling roots, the excavation also shows that most of the trees are planted without removing the synthetic twine, synthetic burlap or wire baskets. This stresses the tree for this hinders the growth of the roots which may affect the growth of the trunk as well. This break through amazed farm and property owners for they are now aware of what is happening on their tree's root system and at the same time arborists are gaining knowledge on this innovation.

Air knives make it much safer for workers to work with underground utilities. Workers use the tool to locate gas and power lines prior to digging; this assures that the tree is free from any kind of hazard when it is planted on the area.

Since then air knife has been an important tool in tree care. Man can now ventilate large areas of soil and incorporate organic matter without harming the roots. Organic matter is essential for soils to come alive with biological activity and processes. Once this is done, results truly are rewarding, trees will only require less maintenance while giving an even more beautiful appearance.

Air knives are not the same as ordinary knives, as they are being used in manufacturing to blow substance from a substance.

Charlotte, NC -- (SBWIRE) -- 05/28/2014 -- Air jets, air curtains, or precision drying systems are all used to describe a device which uses air to blow a substance from a substance. These are known to be called as air knives.

An air knife, a tool used to blow off liquid or debris from products as they travel on conveyors, is normally used as the first part in a recursive recycling process of manufacturing. This knife functions to separate lighter or smaller particles from other components for use in later or subsequent steps, post manufacturing parts drying and conveyor cleaning, part of component cleaning. Uniform sheets, high intensity of laminar airflow, or known as streamline flow are what the knife consists of.

How does it work?

Compressed air flows through an inlet at the end of a port and into a plenum or housing chamber in an air knife. The compressed air leaves the air knife from the plenum chamber while the surrounding air is sucked into the airflow, adding to the amplification ratio of 30:1 at 6 inches. This ratio adheres to the Coanda effect. Then, going down the front down of the air knife, the airflow travels by turning 90 degrees. The combined and now amplified air flow turns into a laminar sheet of air. This uniform sheet of air is converted into reduced energy use, which cools off an application.

What else?

Aside from its use to manufacturing, air knives can be also used as air volume amplifiers. Unique knife shape causes adhering of airstream to the knife surface using the so-called Coanda effect. Coanda effect causes suction of surrounding air increase the total capacity of air flow. It also provides an integrity downstream in a bigger usable range.

The air flow can simply be regulated and thereby is the use of the knife in the application. The different thickness of knives would determinate the thickness of a knife's slot. Thus, this has an effect on dynamic air pressure and its quantity.

What are the types and applications of air knives?

Usually, air knives are used to contain or remove free-standing materials, be it liquids or solids from the surface of the material. The applications involve drying bottles and cans after rinsing and filling, printed circuit boards, metal castings after automatic machining, and many more. They can also transfer heated or cooled air to the surface, or create an invisible air barrier to separate heated or cooled environments from one another in industrial applications.

In many different industries, environments and applications, air knives have a variety of uses. Because of the invisible high velocity, air streams can be discharged by air knife designs of numerous shapes and sizes.

Meanwhile, using air knives would fasten, require less space, and dry oddly shaped parts completely as well as removed solid debris.
