Direct Cooling Platform With Vapor Compression Refrigeration Cycle And Applications Thereof

Abstract

A direct refrigeration cooling platform can cool high heat density sources such as LEDs, IC chip, power amplifiers and laser diodes. The platform utilizes a combination of technologies from a water cooled cold plate design and a vapor compression refrigeration system. The cold plate of the direct refrigeration cooling platform replaces an evaporator in a conventional vapor compression refrigeration cycle. High heat density sources are directly mounted onto the cold plate. Temperature of the cold plate is regulated based on temperature feedback and is maintained above ambient temperatures. For LED applications, a number of LEDs are mounted onto the cold plate of the direct refrigeration cooling platform. Beams of light are distributed via fiber optic light guides to remote and inaccessible locations, where light sources are to be replaced. IC chips are cooled the same way with IC chips attached to the cold plate of the direct refrigeration cooling platform.
