Sectional bar evaporation condenser type self-cooling rectification cabinet

Abstract

The invention discloses a sectional bar evaporation condenser type self-cooling rectification cabinet. The sectional bar evaporation condenser type self-cooling rectification cabinet comprises a cabinet body and a power assembly; the cabinet body comprises a frame, a door plate, an upper cover plate, a lower cover plate, vertical beams, a supporting frame and busbar fixing terminals; the power assembly is composed of a sectional bar evaporation condenser, a power electronic device, an alternating current busbar, a direct current busbar, a fast fuse, a Hall sensor and a fixed mounting frame. Aself-cooling mode is adopted for natural cooling, noise and cost are greatly reduced, energy is saved, emission is reduced, and maintenance is avoided. With the sectional bar evaporation condenser adopted, heat conduction efficiency can be effectively improved, heat resistance is reduced, processing is convenient, appearance is tidy and concise, equipment weight is reduced, and cost is reduced. The sectional bar frame structure is convenient to install and high in corrosion resistance, so that a protection level is enhanced, and standardized production is facilitated, and the problem that a traditional rectification cabinet body consumes energy, generates large noise, is poor in a heat dissipation effect, is exposed to potential safety hazards, and fails to monitor the real-time working temperature of a power electronic device in real time is solved.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a self-cooling rectifier cabinet with a profile evaporation condenser. Background technique [0002] At present, AC-DC rectifiers in the field of power electronics mostly adopt air-cooling and water-cooling methods. The manufacturing cost of the radiator is high, the process is complicated, and the weight is heavy. The aluminum profile radiator is bulky and the heat dissipation capacity is limited. The use of water-cooling method will increase the cost and maintenance workload, and the water-cooling system occupies a large area, and the leakage of the waterway will pose a safety hazard for equipment operation. The traditional rectifier cabinet has no temperature monitoring system and cannot monitor the real-time working temperature of power electronic devices in real time.

Problems solved by technology

[0002] At present, AC-DC rectifiers in the field of power electronics mostly adopt air-cooling and water-cooling methods. The manufacturing cost of the radiator is high, the process is complicated, and the weight is heavy. The aluminum radiator is bulky and the heat dissipation capacity is limited.

The use of water-cooling method will increase the cost and maintenance workload, and the water-cooling system occupies a large area, and the leakage of the waterway will pose a safety hazard for equipment operation. The traditional rectifier cabinet has no temperature monitoring system and cannot monitor the real-time working temperature of power electronic devices in real time. Traditional cabinets Using carbon steel and sheet metal structure, there is insufficient corrosion resistance, and the painting of the cabinet body will be polluted. The profile evaporative condenser type self-cooling rectifier cabinet is a good choice for cost performance
