Heat pipe cooling system and power equipment

Abstract

The invention discloses a heat pipe cooling system, comprising a first pipeline (10) and a second pipeline (20). The first pipeline (10) includes a first steam pipe (12), a first liquid pipe (14) and a pipe connected between the first steam pipe (12) and the first liquid pipe (14). The evaporation section (16), the second pipeline (20) includes a second steam pipe (22), a second liquid pipe (24) and a second steam pipe (22) connected to the second liquid pipe (24) ) between the heat exchanger (26), respectively connected between the first steam pipe (12) and the second steam pipe (22) and between the first liquid pipe (14) and the second between the liquid pipes (24), so that the first pipeline (10) and the second pipeline (20) are combined to form a loop heat pipe, and the loop heat pipe includes a valve (40) and an interface (42) for vacuuming, and the loop heat pipe Refrigerating working fluid is arranged inside, and a capillary structure is arranged inside the evaporating section (16) to provide capillary suction force so that the refrigerant working fluid circulates in the loop heat pipe. The invention has the advantages of high heat transfer efficiency, good reliability and no risk of working medium leakage. The invention also provides a power device.

Description

technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a heat pipe heat dissipation system and electric equipment. Background technique [0002] As the performance and density of IT devices become stronger and higher, the power consumption of the system increases. The traditional air cooling is gradually approaching the limit of its heat dissipation capacity due to the limitation of fan performance and system noise, while liquid cooling High capacity, low noise, more and more people's attention. [0003] In the prior art, the liquid cooling heat dissipation system applied in the cabinet is mainly composed of the cabinet, a circulation system and an external cold source. The circulation system brings the heat in the cabinet to the external cold source to realize heat dissipation. There are many single boards in the cabinet, and the single board is equipped with a heat dissipation pipeline to provide heat dissipation for the ...

AI Technical Summary

Problems solved by technology

Since the working fluid is driven by a pump and the pressure is high, when the board is connected to the system pipeline, there is a risk of leakage at the quick connector, and the liquid dripping onto the board will cause a short circuit in the system

Moreover, the pump is a moving part, the reliability requirements are very high, and backup is required, and the cost is very high
