Abstract

A cooling device for an element such as a microprocessor in a computer, and a process for manufacturing the cooling device. The cooling device provides an effective structure of cooling a microprocessor by providing a metallic filler layer and a metal plate layer spreading out heat generated from the microprocessor, and thereby effectively thermally conducting heat away from the microprocessor. Further, a semiconductor thermoelectric module can be utilized to further cool the microprocessor.
