Problems solved by technology

[0004] Although the above-mentioned semiconductor CPU heat sink 100 has improved heat dissipation efficiency, yet, its described heat shield 160 can be in the alternation state that cold and hot temperature differs greatly when CPU130 works, so just be difficult to guarantee heat shield 160 and heat conductor Always maintain good contact between 140, if the contact is poor, it is easy to cause condensation at low temperature
This semiconductor CPU radiator 100 can make CPU130 work in the state of lower temperature all the time when working, but the lower the temperature is not necessarily the better for CPU130, and described semiconductor refrigerator 150 also is uninterrupted work when CPU130 works , so that its life will not be well guaranteed

Description

【Technical field】 [0001] The invention relates to a heat dissipation device, in particular to a device for cooling heat-generating electronic components. 【Background technique】 [0002] In a computer system or a server system, for heat-generating electronic components, such as a central processing unit (Central Processing Unit, CPU), a heat sink is usually used for heat dissipation and cooling. The existing CPU heat sink is mainly through direct contact with the CPU. The heat sink draws the heat out, and then uses the fan to blow the air to flow and carry the heat away. However, the heat sink of this CPU heat sink directly contacts with the CPU, and the temperature difference between it and the air is not large, so that the heat dissipation effect is not very good. If the ambient temperature is too high, the heat dissipation effect will be even worse, and it is easy to Lead to system slowdown, crash, burn CPU and other consequences. [0003] Please refer to figure 1 , Chi...
