Description

Technical Field

[0001] The utility model relates to a power supply, in particular to a power supply for battery formation. Background Art

[0002] At present, due to the limitations of the production space environment and transportation, the power cabinets and mechanical cabinets of high-power formation and grading equipment are usually split. A large number of cable connections are required between the power cabinet and the mechanical cabinet, which greatly increases the production floor area, transportation, and equipment costs. For this reason, there are also a few high-power formation and grading equipment on the market that integrate the power cabinet and the mechanical cabinet. However, due to the heat dissipation form and installation structure of its power supply part, in order to achieve an ideal heat dissipation effect, it is usually necessary to increase the volume of the radiator, increase the heat dissipation space, and select power devices with higher power. This increases the material cost on the one hand, and on the other hand, it is impossible to miniaturize the high-power formation and grading equipment, thus increasing the production floor area and transportation costs.
