Heat Exchangers

Heat exchangers cool or heat whatever is needed to be cooled or heated. Most simple form of a heat exchanger is a heat sink where heat from a hot source such as a power transistor, chip, motor, is conducted away through contact with a highly conductive metal. For example, an aluminum or a copper plate having fins on one side and a flat surface on the other, in contact with the device being cooled. The fins on a heat sink have a large area in contact with air around them. The air can naturally flow over the fins taking the heat away, or be forced with a fan. A fan significantly increases cooling.

Liquid heat exchangers have passages drilled directly through the material being cooled, or tubes in close contact with the device. Simplest form of a liquid heat exchanger is a cold plate, where the tubes are pressed into the plate, or alternatively the plate has holes drilled through its length.

Cold Plates with Copper Tube, Dual Pass

Aluminum cold plates with copper tubing, dual pass. The plates are flat on one side and have copper tubing press-fit into grooves on the other side. Tubes do not protrude above the surface enabling both side cooling of the cold plate. The tubes are made from copper for improved thermal conductivity over stainless tubes. These plates are an economical and effective option for cooling heat sinks, servers or any device operating in a near-ambient environment.
