The heat exchanger is an integral component in mechanical engineering and can be found in car engines, air conditioners, refrigerators, and much more. They shift heat from one state, such as a liquid or a gas, to another. The movement of heat sometimes conserves it, or, as with air compressors, removes it. If you operate an air compressor, here’s what you need to know about these devices.

Heat Exchangers & Air Compressors

Purpose

Like any other power tool or piece of machinery, air compressors generate heat when in use. Every time air is compressed, it creates heat. When this heat pairs with the atmospheric temperature and humidity, condensation and water vapor can occur. No matter how minute, this moisture can negatively impact the compressor components and project as a whole. With a heat exchanger, you can reduce the heat and the subsequent condensation.

Process

With air compressors, heat exchangers are sometimes referred to as “aftercoolers” because they work after the air is compressed. Since heat moves to areas with colder temperatures, you can perform this process with either a liquid coolant or a mechanical design that relies on natural air convection. With liquid coolants, the compressed air travels through a chamber where the coolant is introduced; the heat from the air then moves to the coolant. Coolant works most efficiently with large-scale compressors. With natural air convection, the compressed air moves through a series of mechanical cooling fins, which help disperse the heat.

Benefits

Having a heat exchanger for your air compressor protects your tools and work. Excess water is always a problem; it can compromise lubricants, create rust, and even clog or freeze lines and tubing. To preserve your equipment for as long as possible and keep your project clear of moisture-related damage, you need an exchanger.
