Problems solved by technology

The disadvantages of this structure are that the layout is simple, the overall space occupation is large, the electrical connection is complicated, the disassembly and maintenance are inconvenient, and some solid radiators are large in size and the heat dissipation capacity is not strong, resulting in increased loss and waste of space.
At the same time, the integral press-fit water-cooling rectifier unit structure used in the past is to pres

Abstract

The invention discloses a rectifying unit structure. The rectifying unit structure comprises a frame, a rectifying bridge unit and a water cooling pipeline system, wherein the frame comprises upper and lower base plates and side plates on the two sides; the rectifying bridge unit is in a press string form, and comprises a top peg, a guide sleeve, a disc spring, a gasket, an insulating disc, a water-cooled radiator, a diode, a top column, a bus bar and a discharge resistor; the water cooling pipeline system comprises a quick joint, a water inlet and outlet passage, a pipeline, a pipe joint and a sealing member. The rectifying unit structure has the advantages that the power device, the radiating device, the bus bar and the like are arranged in the frame by the unit through a press string mechanism, the structure is more compact and attractive, the disassembly, assembly and maintenance are facilitated, the conductive contact is more uniform, and the electric performance is good; the radiating mode is water-cooled radiating, the radiating capacity is high, and the high-power radiating requirement can be met; the water cooling pipeline system is arranged on the outer side of the unit, is good in sealing, convenient to disassemble and assemble and an interface can be quickly plugged and pulled; the bus bar is skilful and rational in design, and the insulation protection is safe and reliable.

Description

technical field [0001] The invention relates to a rectification unit structure, in particular to a rectification unit structure used in the field of high-power frequency conversion. Background technique [0002] With the continuous development of power electronics technology, the performance of power components is constantly upgraded, and the size is also getting larger and larger. The spatial layout of the overall structure, the reliable contact of the conductive contact surface, and the heat dissipation capacity of the radiator are particularly important for the electrical performance. Generally, the structural layout of the rectification unit is generally to simply install and fix the rectification element and the heat dissipation device, and then form a rectification circuit through electrical connection. The disadvantages of this structure are that the layout is simple, the overall space is large, the electrical connection is complicated, disassembly and maintenance ar...
