Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0042] About the microgroove group evaporation heat exchange element in the present invention:

[0043] The micro-groove group evaporative heat exchange element generally refers to engraving dense fine straight grooves on a flat plate of any size, and the capillary force generated in the micro-grooves makes the liquid suck into the micro-grooves. The liquid in each tank has a tiny meniscus near the three-phase (gas, liquid, solid) contact line, and the evaporation of the meniscus has a great local heat transfer coefficient. By designing the optimal size and structure layout, its heat transfer may be higher than or several times the critical heat load of general pool boiling. And it has the characteristics of arbitrary heat transfer size and huge total heat transfer. Therefore, this heat exchange technology may have an important application prospect in the h...

Abstract

The invention provides a high-performance passive phase-change heat loss system which comprises a micro groove group evaporator which is connected with the capillary pump loop which is connected with the chiller. The invention also provides a phase-change heat loss system used in desk computer and a heat loss system used in notebook computer.

Description

technical field [0001] The present invention relates to the technology of passive phase change heat exchange for heating working elements or components, especially a high-performance passive phase change heat dissipation system and its application. The specific applications include phase change heat dissipation systems for desktop computers and notebook Cooling system in small spaces such as computers. Background technique [0002] The heat generation density of high performance chips will soon reach 60W / cm 2 Degree. Such a heat flux is at the same level as the core heat flux of a light water reactor (LWR), but the difference between the heat dissipation surface temperature and the ambient temperature required by the former is much lower than that of the latter. The computer's thermal control technology, that is, cooling technology requirements, must not only meet its allowable upper limit temperature (about 100oC), but also meet the ever-increasing heat dissipation heat f...
