Technical Field

[0001] The utility model belongs to the technical field of electrical equipment, in particular to a receiving end rectifier load module. Background Art

[0002] Rectification is an essential component of variable frequency drive systems. Existing rectifier modules primarily rely on forced air cooling for heat dissipation. This is achieved by adding a heat sink or fan and creating an air duct with a sheet metal housing. The components of existing rectifier modules, such as the heat sink, fan, and sheet metal housing, result in large and expensive rectifier modules. Furthermore, air cooling can be noisy and ineffective, limiting the power output of individual rectifier modules.

[0003] In the prior art, Publication No. CN216389340U provides a rectifier module comprising a base plate, a water-cooling plate disposed on one side of the base plate, 3N diode assemblies disposed on a side of the water-cooling plate away from the base plate, and a DC copper busbar and an AC copper busbar disposed on a side of the 3N diode assemblies away from the water-cooling plate. The DC copper busbar and the AC copper busbar are respectively connected to the 3N diode assemblies. The 3N diode assemblies convert the AC power input by the AC copper busbar into DC power, which is output through the DC copper busbar. The water-cooling plate provides water cooling for the 3N diode assemblies. This utility model solves the problems of large size and high cost of rectifier modules in the prior art, effectively reducing the module size, saving module cost, improving heat dissipation, and reducing noise.
