Problems solved by technology

Charging piles using this heat dissipation method generally have the characteristics of large volume and weight, poor heat dissipation effect, and high working noise.
This kind of charging product has the following disadvantages: first, the thickness of the heat dissipation fins is large, the heat dissipation area per unit volume is small, and the heat dissipation efficiency is low; the second is to obtain a larger heat dissipation area, which will lead to a substantial increase in the volume and weight of the product. ; The third is that the windward area of ​​the fan is small, and the number of fans is large, which will lead to high working noise; the fourth is that the use of more heat-conducting links and larger shell parts will lead to difficult production and high manufacturing costs
[0004] The tube belt air coolers commonly used in the market today generally use a single row of heat dissipation pipes, which has a small heat dissipation area and low overall heat dissipation efficiency.

Description

technical field [0001] The invention relates to the technical field of charging devices for electric vehicles, in particular to a liquid-cooled and heat-dissipating DC charging device. Background technique [0002] With the vigorous promotion and application of electric vehicle technology, the output of electric vehicles is increasing day by day, and electric vehicles have entered thousands of households. At the same time, the output of electric vehicles has grown exponentially, and the demand for charging piles is also huge. Although the number of charging piles is also increasing rapidly, the growth scale of the number of new energy vehicles is much higher than the growth scale of the number of charging piles. The rapid expansion of the production scale of the electric vehicle industry has promoted the rapid development of the charging pile industry. On the contrary, the lag in the development of the charging pile industry will seriously affect the expansion of the produ...
