Description

Technical Field

[0001] The utility model relates to the technical field of water cooling plates, and particularly relates to a heat dissipation water cooling plate. Background Art

[0002] A water cooling plate, also called a liquid cooling plate, with the English name coldplate, is a component of a water cooling radiator. It is a component that exchanges heat through liquid cooling. Its principle is to form flow channels inside a metal plate. The heat source exchanges heat on the surface of the water cooling plate, and the heat is transferred to the flow channels. The coolant enters the flow channels of the water cooling plate from the inlet of the water cooling plate, and then flows out from the outlet of the water cooling plate and takes away most of the heat. When the water cooling plate is used, the liquid is forced to circulate under the drive of a pump to take away the heat of the heat source on the surface of the water cooling plate. Compared with the air cooling system, the water cooling plate heat dissipation system has multiple advantages. First of all, the water cooling plate runs more quietly. Secondly, the cooling effect of the water cooling system is more stable and is not easily affected by the ambient temperature. Most importantly, due to the large heat capacity of water, the water cooling system has excellent heat load capacity, which means it can absorb and disperse heat more effectively.

[0003] For the existing water cooling plates, the heat dissipation area in the flow channels is limited, and there is still a problem of insufficient heat dissipation effect. Summary of the Invention

The head and tail ends of the flow channels are respectively communicated with the liquid inlet hole and the liquid outlet hole. A plurality of heat dissipation ridges distributed in the flow channels are convexly provided on the surface of the inner cavity.

[0006] Preferably, the plurality of heat dissipation ridges are evenly spaced.

[0007] Preferably, the shape of the heat dissipation ridge is in the shape of a rack.

[0021] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with the embodiments and the drawings. The content mentioned in the embodiments does not limit the present utility model.

[0022] Embodiment 1

[0023] As Figures 1 - 4As shown in the figure, a heat dissipation water-cooled plate includes a water-cooled plate body 1 and side cover plates 2 hermetically connected to both sides of the water-cooled plate body 1. The water-cooled plate body 1 is provided with an inner cavity 3. The inner cavity 3 is provided with a plurality of water baffle strips 4. The plurality of water baffle strips 4 are arranged in parallel and staggered to form a flow channel 5 for liquid flow. The water-cooled plate body 1 is provided with a liquid inlet hole 6 and a liquid outlet hole 7. The head and tail ends of the flow channel 5 are respectively communicated with the liquid inlet hole 6 and the liquid outlet hole 7. The surface of the inner cavity 3 is convexly provided with a plurality of heat dissipation ridges 8 distributed in the flow channel 5.

[0024] For this heat dissipation water-cooled plate, the water-cooled plate body 1 and the side cover plates 2 hermetically connected to both sides of the water-cooled plate body 1 are adopted. The water-cooled plate body 1 is provided with an inner cavity 3. The inner cavity 3 is provided with a plurality of water baffle strips 4. The plurality of water baffle strips 4 are arranged in parallel and staggered to form a flow channel 5 for liquid flow. The water-cooled plate body 1 is provided with a liquid inlet hole 6 and a liquid outlet hole 7. The head and tail ends of the flow channel 5 are respectively communicated with the liquid inlet hole 6 and the liquid outlet hole 7. The surface of the inner cavity 3 is convexly provided with a plurality of heat dissipation ridges 8 distributed in the flow channel 5, so as to increase the contact area between the flow channel 5 and the coolant, increase the heat dissipation area inside the flow channel 5, and improve the heat dissipation efficiency.

[0025] Furthermore, the plurality of heat dissipation ridges 8 are evenly spaced, which is more conducive to the uniform heating and heat absorption of the coolant in the flow channel 5 and improves the heat dissipation efficiency of the water-cooled plate.

[0026] Furthermore, the shape of the heat dissipation ridge 8 is in the shape of a rack, which is conducive to increasing the heat exchange area in a limited space and improving the heat exchange effect.

[0027] Furthermore, the width between two adjacent water baffle strips 4 is greater than the width of the water baffle strip 4. Further, the width between two adjacent water baffle strips 4 is 5-10 times the width of the water baffle strip 4, which can not only ensure that a plurality of water baffle strips 4 are arranged in parallel and staggered to form a flow channel 5 for liquid flow, but also make the width of the flow channel 5 wider, which is conducive to increasing the heat dissipation area inside the flow channel 5 and improving the heat dissipation efficiency. Preferably, the width between two adjacent water baffle strips 4 is 7 times the width of the water baffle strip 4.

[0028] Furthermore, processing openings 9 communicating with the inner cavity 3 are provided on both sides of the water-cooled plate body 1, and the side cover plates 2 are hermetically welded to the processing openings 9 one by one. The water-cooled plate body 1 and the side cover plates 2 on both sides of it are hermetically welded to form an integrated water-cooled plate, which is conducive to avoiding water leakage of the water-cooled plate.

[0029] Furthermore, assembly through holes 10 are provided at the four corner ends of the water-cooled plate body 1, so as to assemble this heat dissipation water-cooled plate in the equipment to be cooled by means of fasteners such as screws for fixed use.

[0030] Further, a plurality of screw holes 11 are formed in the top surface of the water-cooling plate body 1. This radiating water-cooling plate is particularly suitable for the water-cooling heat dissipation of an electric bicycle controller or an electric motorcycle controller. In actual use, the electric bicycle controller or the electric motorcycle controller is fixed to the top surface of the water-cooling plate body 1 through the screw threaded engagement with the screw holes 11, so as to facilitate the heat dissipation of the electric bicycle controller or the electric motorcycle controller.

[0031] Embodiment 2

[0032] The difference between this embodiment and Embodiment 1 is that:

[0033] As Figure 5 shown, in this embodiment, a reinforcing plate 12 is convexly provided at the bottom of the water-cooling plate body 1 so as to improve the strength of the bottom surface of the radiating water-cooling plate.

[0034] The above embodiments are the preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the protection scope of the present invention.
