Abstract

The invention discloses a heat dissipation device, which comprises a heat dissipation plate and a uniform temperature plate, and is characterized in that the heat dissipation plate is internally provided with a liquid cooling channel and/or heat dissipation fins; the first side of the uniform-temperature plate is attached to one side of the heat dissipation plate, the second side surface of the uniform-temperature plate is a heat source part mounting surface, a plurality of uniform-temperature channels are formed in the uniform-temperature plate, and the uniform-temperature channels are filled with phase change working media; a first area and a second area are formed on the uniform-temperature plate, the heat source piece is installed on the surface of the first area, and the uniform-temperature channel guides heat of the heat source piece from the first area to the second area. According to the technical scheme, the problem that heat is concentrated and cannot be diffused during heat dissipation is solved, and the heat dissipation utilization rate of the heat dissipation plate is increased.

Description

technical field [0001] The invention relates to the technical field of frequency conversion cabinets, in particular to a cooling device. Background technique [0002] In the field of heat dissipation, the radiator is mainly used to dissipate heat for devices with large heat loss, and quickly transfer the heat of the device to the heat sink to ensure that the device can work normally and stably. How to quickly transfer heat from the radiator to the ambient heat sink is very important. Commonly used liquid-cooled plate radiators usually increase the flow channel at the radiator base plate, so that the cooling fluid flows through the liquid-cooled plate below the device, carrying the cooling heat of the electronic device to reduce the temperature of the electronic device. However, when a liquid-cooled plate radiator is currently used, the temperature of the liquid-cooled plate near the installation position of the electronic device is higher, and the temperature in other place...
