Cooling Electronics Down With Cabinet Coolers

As the summer days have reached maximum temperatures, I find myself busting out my kayak and heading down to the wild whitewater rivers for a weekend full of adventure in the cool water. I personally am not a fan of the heat and as most people enjoy the water and swimming, I partake in the high adventure sport of whitewater kayaking. I’ve been around the sport of whitewater most of my life and have kayaked some of the hardest rivers east of the Mississippi including the well-known rivers of the Upper Gauley, the New River, and the Tallulah.

When the temperature rises and I start to overheat and kayaking is the best way that I enjoy to cool off and enjoy the weekend; splashing around in the wild waves. With plenty of summer heat ahead of us it’s a perfect chance for all to get outside and jump in a lake, swimming pool, or even a river to cool down and take a chance to enjoy a little fun.

But what about your electrical cabinets; they deserve to stay nice and cool on the inside as well. All electrical components are not 100% efficient meaning that when an electrical current is flowing through them a certain amount of heat is generated. This phenomenon is commonly referred to as heat loss and VFD’s and other drives are typical offenders. Heat loss is not the only thing that can attribute to electrical cabinets overheating, sun light is another big factor for outside electrical cabinets. Based on the color of a cabinet sitting out in the sun a specific percentage of heat is absorbed into the cabinet; black absorbs the most heat and white absorbs the least. In most cases solar heat can be negated by installing a cover over top of the cabinet to provide shade.

At EXAIR we have designed a cost-effective way to cool down these overheated cabinets during these summer months. EXAIR’s Cabinet Coolers are designed to provide cooling using just a source of compressed air; they utilize our vortex tube to provide a constant source of cold air as long as they are connected to a source of compressed air. Our Cabinet Coolers have also been designed to be used in a large variety of environments ranging from standard production to Classified environments.

EXAIR also can provide our Electronic Thermostat Control system or ETC for short which can give a user much better control over the temperature inside the cabinet as well as visual feedback of the internal temperature. The ETC allows for easy and constant changing of what internal temperature is desired. The ETC will also provide live temperature readings on the internal temperature of the cabinet.

If you have any questions about compressed air systems or want more information on any of EXAIR’s products, give us a call, we have a team of Application Engineers ready to answer your questions and recommend a solution for your applications.
