Problems solved by technology

Among them, the rationality of heat dissipation of the power module will directly affect the service life of the product, and the existing power devices such as capacitors are usually installed inside the IBGT cooling air duct or placed outside to naturally dissipate heat, which may easily cause the excess heat of the capacitor to be dissipated quickly. It is easy to accumulate and generate high temperature to cause damage to the capacitor, which makes the replacement of power devices frequent and costly

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereby.

[0025] Such as Figure 1 to Figure 3 As shown, the converter power module of this embodiment includes a capacitor component 1 , a power component 2 , a natural cooling air duct 3 and a forced cooling air duct 4 . Among them, the capacitor assembly 1 is arranged in the natural heat dissipation air duct 3, and the power assembly 2 is arranged in the forced heat dissipation air duct 4, which makes the capacitor assembly 1 and the power assembly 2 respectively provided with independent heat dissipation channels, avoiding that the capacitor assembly 1 is not independent. The problem of poor heat dissipation caused by heat dissipation ensures that the excess heat of the capacitor assembly 1 can be effectively and quickly dissipated, so that the capacitor assembly 1 ha...

Abstract

The invention provides a converter power module, which comprises a capacitor assembly and a power assembly. The converter power module also comprises a natural heat dissipation wind channel and a forced heat dissipation wind channel, which are arranged side by side. The wind direction in the natural heat dissipation wind channel is the same with or opposite to the wind direction in the forced heatdissipation wind channel. The capacitor assembly is arranged in the natural heat dissipation wind channel; and the power assembly is arranged in the forced heat dissipation wind channel. The converter power module has the advantages of good heat radiation effect and low cost and high integration degree and the like.

Description

technical field [0001] The invention relates to the field of heat dissipation of power modules, in particular to a converter power module. Background technique [0002] With the competition in the new energy market, the power density of the power unit is increasing, and the module composed of semiconductor devices has higher requirements in terms of volume and assembly efficiency. Existing power modules usually adopt an integrated design, integrating components such as capacitors, IGBTs, and busbars together to form an independent functional unit structure. Among them, the rationality of heat dissipation of the power module will directly affect the service life of the product, and the existing power devices such as capacitors are usually installed inside the IBGT cooling air duct or placed outside to naturally dissipate heat, which may easily cause the excess heat of the capacitor to be dissipated quickly. It is easy to accumulate and generate high temperature to cause dama...
