Abstract

The invention discloses a heat radiation device for an air reactor. The heat radiation device comprises a cabinet, a fan and the air reactor, and the air reactor is positioned in the cabinet. A lateral side of the cabinet is provided with an air passage port, and the fan is connected to the lateral side and used for blowing inwards the cabinet through the air passage port. By the fan for providingconvection air into the cabinet, heat generated by a coil of the air reactor can be taken out by air motion in the air reactor and air motion in a space between the cabinet and the air reactor. The heat radiation device for the air reactor is simple in structure, high in heat radiation completeness and uniformity and small in size.

Description

technical field [0001] The invention relates to reactor technology, in particular to a cooling device for an air-core reactor. Background technique [0002] With the rapid development of industry, large-scale power electronic equipment is more and more widely used in various industries, the power level is also higher and higher, and there are more and more restrictions on the volume of equipment. [0003] Magnetic components are one of the most important parts of power electronic equipment, which largely determines the performance, efficiency and size of the whole machine. Reactors, especially air-core reactors, play an important role in traction converters. Therefore, the increase of system power and the limitation of volume have brought great challenges to the design of magnetic components, and the heat dissipation of magnetic components has become a bottleneck. [0004] The existing air-core reactor cooling device has the problems of complex structure, insufficient and u...
