DC-DC module power supply liquid cooling passage

Abstract

The invention relates to a DC-DC module power supply liquid cooling passage comprising a power supply shell (1), a liquid inlet (2), a front liquid cooling passage section (3), a middle liquid cooling passage section (4), a rear liquid cooling passage section (5), a liquid outlet (6) and a cover plate (10). The liquid inlet (2) and the liquid outlet (6) are arranged in the side wall of the power supply shell (1) symmetrically and longitudinally, the front liquid cooling passage section (3), the middle liquid cooling passage section (4) and the rear liquid cooling passage section (5) communicated with one other are arranged on the front side of the power supply shell (1) from the liquid inlet (2) to the liquid outlet (6) sequentially, and the cover plate (10) covers the liquid cooling passage formed by the liquid inlet (2), the front liquid cooling passage section (3), the middle liquid cooling passage section (4), the rear liquid cooling passage section (5) and the liquid outlet (6). The DC-DC module power supply liquid cooling passage has the advantages that flowing distance of cooling liquid in the shell is lengthened by arranging slow flow plates on two side walls of the liquid cooling passage, and the DC-DC module power supply liquid cooling passage is simple in structure, good in cooling effect and high in connection strength.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a DC-DC module power supply liquid cooling channel. Background technique [0002] With the rapid development of microelectronics technology, the power consumption of electronic equipment modules is increasing, and the traditional air cooling technology can no longer meet the heat dissipation requirements of the modules. Compared with gas, the thermal conductivity and specific heat capacity of liquid are much higher, so liquid cooling technology is a better way to solve the cooling and heat dissipation of large power consumption modules. [0003] DC-DC module power supply is widely used in communication fields such as switching equipment, access equipment, mobile communication, microwave communication, optical transmission, routers, as well as automotive electronics, aerospace and other fields. When in use, the system selects the number of matching DC-DC module power supplies according...

AI Technical Summary

Problems solved by technology

[0004] At present, the liquid cooling technology adopted by the DC-DC module power supply only considers the circulating flow of the coolant in its liquid cooling channel, while ignoring the influence of the coolant flow path on the heat dissipation effect of the module power supply

Normally, the cooling liquid passes through the liquid cooling channel in an unobstructed form, and the flow distance of the cooling liquid in the liquid cooling channel is relatively short, so it can only dissipate heat locally on the module power supply, but the overall heat dissipation effect cannot meet the requirements
