Heat Exchanger - Pico

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.

Complete Your Liquid Loop with ATS

ATS has the products needed to design a complete liquid cooling loop : iCDMs (Industrial Cooling Distribution Modules), Tubed and High Performance Cold Plates to transfer and remove the heat from the source; Heat Exchangers to transfer heat from the liquid to the air with or without a fan; Chillers to circulate and condition the fluid in the system, Compact Refrigeration Modules for very high capacity cooling. In addition , ATS offers Flow Meters to measure the volumetric flow rate of the fluid in the system and Leak Detectors to notify users of any leaks in the system.
