The Central Processing Unit (CPU) generates a great deal of undesirable heat in modern computing systems. The CPU is responsible for processing most of the data within systems and is often referred to as a computer’s central processor or simply processor. As data is processed within a system, heat is generated. Once heat thresholds are exceeded, CPUs are placed at risk of malfunction or permanent damage. MORE
Often in high power density or low profile heat sink applications, the spreading resistances in the base of the heat sink limits the performance of the design. Once it is determined that normal heat sink materials, aluminum or copper, are either insufficient or too bulky to meet the design objectives, the obvious next step is to look at two phase spreading devices, such as heat pipes or vapor chambers.
