High-power module heat dissipation structure

Abstract

The invention provides a high-power module heat dissipation structure which comprises an aluminum substrate, a first high-power module set is placed on the upper layer of the aluminum substrate, a second high-power module set is placed on the lower layer of the aluminum substrate, and a first heat conduction patch set is arranged between the first high-power module set and the aluminum substrate and used for transferring heat of the first high-power module set to the aluminum substrate. A second heat conduction patch set is arranged between the second high-power module set and the aluminum substrate and used for transmitting heat of the second high-power module set to the aluminum substrate, a high-density radiator is installed below the aluminum substrate and makes contact with the aluminum substrate, and a center substrate is installed in the aluminum substrate. According to the high-power module heat dissipation structure provided by the invention, heat is concentrated and dispersed by utilizing spatial layout, the heat of each module on the aluminum plate is transferred to the high-density radiator by matching with the high-density radiator and utilizing the high heat conduction performance of the heat pipe, and meanwhile, the centrifugal fan is additionally arranged in the middle of the high-density radiator; heat of the radiator can be effectively brought out by the centrifugal fan in the center for effective heat dissipation.

Description

technical field [0001] The invention relates to the technical field of heat dissipation devices, in particular to a heat dissipation structure of a high-power module.
