Description

technical field [0001] The invention relates to the technical field of liquid cooling and heat dissipation, in particular to a liquid cooling plate radiator. Background technique [0002] At present, more and more electronic devices adopt liquid cooling to dissipate heat. [0003] In the prior art, a common liquid-cooled heat dissipation method is to use a liquid-cooled plate to dissipate heat. For example, attach a hashboard with chips and other heating elements attached to one or both sides of the liquid-cooled plate, and then the cooling liquid flows in from the inlet. Inside the liquid-cooled plate, the cooling liquid flows through the channel and then flows out from the outlet, so that the circulating flow realizes the liquid cooling and heat dissipation of the power plate. [0004] However, in the above solution, the coolant flow channel of the liquid cooling plate is usually linear, the flow channel is single, and the heat dissipation area is limited, which leads to ...

Problems solved by technology

[0006] That is to say, in view of the above-mentioned technical problem that when the cooling sub-channel is in a single linear shape, the heat dissipation area of ​​the cooling liquid is limited and the heat dissipation efficiency is not high when the cooling liquid flows through the cooling sub-channel, the embodiment of the present application adopts A number of fin units are arranged in front and rear dislocations along the flow direction of the cooling liquid on the heat sink sub-channel, so that, on the one hand, the fins of the fin unit increase the contact area between the radiator of the liquid cold plate and the cooling liquid, thereby improving On the other hand, the fins of the front and rear adjacent fin units are misplaced, which causes the coolant to flow between the two adjacent fin units when it flows from the previous fin unit to the next fin unit. It is easy to understand that this disturbance enhances the convective heat transfer intensity of the cooling liquid, thereby enhancing the heat transfer effect between the cooling liquid and the fin unit; The single linear shape leads to technical problems such as limited heat dissipation area and low heat dissipation efficiency, which effectively improves the contact area between the liquid cold plate radiator and the coolant, and improves the heat dissipation efficiency by increasing the disturbance of the coolant, with a simple structure
