Injection enhancement radiator

Abstract

The invention provides an injection enhancement radiator. The radiator comprises an injection control cavity with an opening in the upper side, a heat dissipation substrate covering the opening in theupper side of the injection control cavity, an injection device arranged on the lower portion in the injection control cavity, and a high-pressure conveying device used for conveying high-pressure cooling liquid to the injection device; a spraying device which is used for spraying high-pressure cooling liquid upwards to form high-pressure spray, wherein the upper surface of the heat dissipation substrate is used for arranging a heating element. The radiator can effectively dissipate heat of a high-flow-density heating element, and is simple in structure, low in manufacturing difficulty and low in machining cost.

Description

technical field [0001] The invention relates to the technical field of radiators, in particular to a spray-enhanced radiator. Background technique [0002] At present, high-power electronic equipment components typically represented by supercomputing CPUs or high-power power supply IGBT components have shown a polarized trend of maximizing power loads and minimizing component sizes. The performance of various electronic components in electronic equipment Getting stronger and stronger. At the same time, within the limited volume space, the integration density of these electronic components in the equipment or in the PCB board is getting higher and higher. In the future, the power of these high-precision, high-power devices will continue to increase, the heat consumption of the entire device will also range from tens of kilowatts to megawatts, and the heat generation of its core electronic components will also range from several thousand watts to tens of kilowatts.

Problems solved by technology

This type of design generally causes the following problems: due to the sharp increase in the heat flux density of the heating element, the radiator will also be forced to seek a larger heat dissipation area to meet the heat dissipation requirements, which will inevitably increase the number of fins, increase the length of the fins, and reduce the heat dissipation. The thickness of the ribs is thicker, and the spacing between the ribs is reduced, so the difficulty of processing is bound to increase, and the cost is bound to increase. After the spacing of the fins is reduced, the flow of coolant is blocked, and the pressure loss is bound to increase.
