Abstract

The invention provides an air-cooled liquid-cooled combined thermally superconducting plate type heat sink, comprising a thermally superconducting plate, a sealing passage formed in the thermally superconducting plate and communicated with each other, and a heat transfer working medium filled in the sealing passage; a liquid-cooled radiator located on the surface of the thermal superconducting plate, wherein a liquid passage is formed in the liquid-cooled radiator, and a liquid inlet port and a liquid outlet port communicated with the liquid passage are arranged on the liquid-cooled radiator;a first heat dissipation fin located on at least one surface of the thermal superconducting plate, wherein a plurality of first heat dissipation channels arranged in parallel spaces are formed in thefirst heat dissipation fin; at least one fan is position at one end of that first heat dissipation fin, and the air outlet surface of the fan faces the first heat dissipation fin and is perpendicularto the extending direction of the first heat dissipation passage. The invention has the following beneficial effects: the forced heat dissipation mode is flexible, the heat dissipation ability is remarkably enhanced, and another device can be used for forced heat dissipation when any device of air cooling or liquid cooling fails, which does not affect the heat dissipation effect, and has high reliability.

Description

technical field [0001] The invention belongs to the technical field of heat transfer, in particular to an air-cooled and liquid-cooled combined thermal superconducting plate radiator. Background technique [0002] With the rapid development of power electronics technology, the requirements for modularization, integration, light weight, low cost and high reliability are getting higher and higher, and the heat generated by power devices during operation is also increasing. Quickly dissipating the heat generated by the power device will cause the temperature of the chip in the power device to rise, which will cause a decrease in performance and shorten the service life, and will lead to the failure of the power device and the burning of the chip. Therefore, solving the heat dissipation problem of power devices has always been one of the core issues that plague power device packaging manufacturers and users. In order to effectively solve the heat dissipation problem of power de...
