Embodiment Construction
[0032] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0033] Such as Figure 1-4 As shown, the shovel tooth phase change radiator according to an embodiment of the present invention includes a heat dissipation base 10, a shovel tooth heat dissipation unit 20, and a heat dissipation cover 30. The heat dissipation base 10 and the heat dissipation cover 30 are arranged at relative intervals. 20 is connected between the heat dissipation base 10 and the heat dissipation cover 30 . The heat dissipation base 10 is attached to the heat generating device, and the heat generated by the heat generating device is transferred to the heat dissipation base 10 and finally dissipated to the external environment through the shovel tooth heat dissipation unit 20 .
[0034] Wherein, the heat...

The invention discloses a form relieved tooth phase change radiator which comprises a radiating base, form relieved tooth radiating units and a radiating cover plate. A refrigerant chamber is arranged in the heat dissipation base; a heating area is arranged on the first surface of the heat dissipation base, the relieving tooth heat dissipation unit is arranged on the second surface of the heat dissipation base, and the heat dissipation cover plate is arranged on the relieving tooth heat dissipation unit; the form relieved tooth heat dissipation unit comprises at least one flat tube and a plurality of form relieved teeth arranged on at least one surface of the flat tube; the flat tube is vertically connected between the heat dissipation base and the heat dissipation cover plate and is communicated with the refrigerant chamber; a plurality of partition plates are arranged in the flat tube to divide an internal channel of the flat tube into a plurality of flow channels; the heat dissipation cover plate is provided with a flow guide groove, and the flow channels in the flat pipes are communicated through the flow guide groove. According to the form relieved tooth phase change radiator, the interior of the flat pipe is divided into the multiple flow channels, the flow channels are communicated through the flow guide grooves in the heat dissipation cover plate, self-circulation of condensation is achieved, and the heat dissipation effect and the heat dissipation efficiency of the radiator are improved.
Description
technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a shovel tooth phase change radiator. Background technique [0002] With the rapid development of chip technology, high-integration, high-precision, high-frequency chip phase sequence comes out, and with the improvement of chip performance, it brings higher calorific value. In order to ensure the normal operation of the CPU in the appropriate temperature range, it is forced to cool it outside to ensure that the components will not overheat and fail. The various air-cooled and water-cooled radiators currently on the market are difficult to meet the requirements of light structure and efficient heat dissipation. customer demand. [0003] In order to meet the demand, phase change radiators have appeared on the market, which use the heat vaporization and condensation liquefaction of phase change working fluid to take away heat. However, the existing phase-change radiators ...
