Problems solved by technology

At present, the commonly used heat dissipation methods for power modules such as IGBTs include air cooling, heat pipes, and liquid cooling. Among them, air-cooled radiators are widely used for heat dissipation of power modules due to their relatively low cost, short production cycle, and high reliability. The existing air-cooled radiator is a single-segment, open structure, and the heat dissipation efficiency is low

Abstract

The invention provides a gear shaping type air cooling radiator, which comprises a base plate and a U-shaped tooth piece, wherein a plurality of gear shaping assemblies which are evenly distributed are arranged on the base plate, each gear shaping assembly comprises two tooth piece grooves which are in bilateral symmetry, the U-shaped tooth piece is connected with the base plate through the tooth piece grooves, and an annular closed air channel is formed in the U-shaped tooth piece. Compared with an existing air cooling radiator, the gear shaping type air cooling radiator is internally provided with the U-shaped tooth pieces with the annular closed air channels, when air passes through the U-shaped tooth pieces, a large amount of heat is taken away, the heat conduction performance of the U-shaped tooth pieces is fully exerted, so that the efficient heat dissipation effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of radiator equipment, and in particular relates to a pin-slotted air-cooled radiator. Background technique [0002] At present, the application of electronic equipment in high-speed rail, wind power and other industries is increasing. The power module is the core component of the inverter. With the gradual development of products in the direction of high frequency, high power and high integration, the heat dissipation requirements for power modules such as IGBT are increasing. The higher, so a reasonable and efficient heat dissipation method must be adopted. At present, the commonly used heat dissipation methods for power modules such as IGBTs include air cooling, heat pipes, and liquid cooling. Among them, air-cooled radiators are widely used for heat dissipation of power modules due to their relatively low cost, short production cycle, and high reliability. The existing air-cooled radiator has a single t...
