Compact Heat Exchangers

ATS picoHEX™ heat exchangers add high performance cooling to small form factor applications where traditional size exchangers will not fit. Their compact design is built on the ATS family of UltraCool CPU coolers, and their cooling properties are consistent with ATS’ wide line of exchangers. picoHEX™ heat exchangers can be used for cooling CPUs, GPUs, FPGAs and other high power components.

The tube-to-fin, liquid-to-air design of picoHEX™ compact heat exchangers includes the industry’s highest density fins. This feature maximizes heat transfer from liquid to air, allowing the liquid to be cooled to lower temperatures than other heat exchangers on the market. The fins and tubes are made of copper and stainless steel and can be used with a wide variety of fluids, including water, dielectric fluids and custom designed heat transfer fluids.
