Description

Technical Field

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

[0002] Due to the large volume and low power density of traditional finned air-cooled radiators, they cannot meet the usage requirements of ultra-large (100MW - 400MW) energy storage systems. However, the characteristics of small volume and high heat dissipation power density of liquid cooling technology can greatly reduce the volume of ultra-high power energy storage systems, reduce the overall system cost, and facilitate transportation and installation. Therefore, liquid cooling plate heat dissipation has developed rapidly. In a single-channel water cooling plate, the flow channel is generally arranged in an S shape, and the inflection point position between two adjacent parallel flow channel segments is connected by an arc transition. However, for a relatively wide flow channel, the liquid is prone to mixed flow when passing through the inflection point position, resulting in uneven heat transfer efficiency. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a water cooling plate to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or creation condition.

[0004] The technical solution adopted to solve the above technical problems: A water cooling plate, comprising: a base body, a flow channel is opened in the base body, two through openings respectively communicating with both ends of the flow channel are opened on one side of the base body, the flow channel includes at least two straight sections and at least one arc section, both ends of the arc section are respectively connected to two adjacent straight sections, straight partition bars are formed in the straight sections, arc partition bars are formed in the arc section, both ends of the arc partition bars are respectively connected to two adjacent straight partition bars, so that all the straight partition bars and the arc partition bars in the same flow channel are connected to each other at intervals to form a total partition bar, and the shape of the total partition bar adapts to the shape of the flow channel.

[0005] This technical solution has at least the following beneficial effects: When the cold liquid flows into the flow channel from one of the through openings, under the guidance of the total partition bar formed by the straight partition bars and the arc partition bars, the flow direction and flow rate of the cold liquid are both stable and reliable, so as to ensure the cold liquid flow balance at the inflection point position in the flow channel, ensure the uniformity of the heat transfer efficiency at the inflection point position of the flow channel, and improve the heat transfer effect. In addition, under the guidance of the total partition bar, the overall liquid resistance in the flow channel is small, so as to reduce the turbulence situation when the liquid in the flow channel changes direction. Even if the inlet and outlet liquid pipelines of multiple water cooling plates are connected in series, a relatively large inlet liquid pressure can still be maintained.

[0006] As a further improvement of the above technical solution, two flow channels are provided in the base body. The two flow channels are communicated with each other at both ends respectively, and the two flow channels are symmetrically distributed along the middle plane of the base body. When the cold liquid enters from one through-port, it will be divided into two flow channels, so that both flow channels have cold liquid passing through, enabling both sides of the base body to have a heat dissipation effect. Moreover, the symmetrically arranged flow channels can make the heat dissipation effects of the two flow channels the same, ensuring the same cooling effect for both.

[0007] As a further improvement of the above technical solution, grooves are provided on the side walls of the two flow channels that are close to each other at the same end. When the cold liquid flows to the grooves, under the action of the side walls of the grooves, the water flow is made to flow away from the bottom wall of the grooves, so that the cold liquid can flow closer to one side of the heat dissipation surface, improving the heat dissipation effect.

[0008] As a further improvement of the above technical solution, four straight sections are provided, and three arc sections are provided. By reasonably setting the numbers of the straight sections and the arc sections, while enabling the two through-ports to be in the same direction, it can also ensure a reasonable number of inflection points in the flow channels, guaranteeing the overall heat dissipation effect.

[0009] As a further improvement of the above technical solution, a buffer cavity is provided between the end of the flow channel and the corresponding through-port, and the side wall of the buffer cavity close to the arc section is provided with an arc surface adapted to the arc section. It can be understood that at this time, the width of the rib formed between the inner side wall of the flow channel and the inner side wall of the buffer cavity is relatively small, which can increase the heat dissipation area, thereby improving the heat dissipation effect of the water-cooled plate.

[0010] As a further improvement of the above technical solution, the flow channels are provided on one side of the base body, and a cover plate for closing the flow channels is installed on one side of the base body. This can facilitate the processing of the flow channels, improve production efficiency, reduce manufacturing costs, and enhance economy.

[0011] As a further improvement of the above technical solution, the side wall of the arc section is an arc surface, and both side walls of the arc partition are arc surfaces. Through the guidance of the arc surface, the turbulence formed by the liquid commutation in the flow channel can be effectively eliminated, reducing the flow channel resistance to the lowest level.

[0012] As a further improvement of the above technical solution, the width of the arc partition is smaller than the width of the straight partition. When the cold liquid flows from the straight section to the arc section, the flow rate of the cold liquid can be slightly reduced, improving the flow stability of the cold liquid in the arc section and ensuring the corresponding cooling effect of the arc section.

[0013] As a further improvement of the above technical solution, at least two main partitions are arranged side by side. Arranging two or more main partitions can further improve the flow stability and reliability of the cold liquid, thereby ensuring the balance of cooling and heat dissipation.

[0014] As a further improvement of the above technical solution, guiding inclined surfaces are provided on both sides of the end of the total partition bar, so that the cold liquid can be smoothly and stably divided by the total partition bar. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Referring to Figures 1-3 , a water cooling plate includes a base body 10, the base body 10 is a flat square-shaped aluminum plate, and flow channels 20 are provided on both side surfaces of the base body 10. Taking the middle surface parallel to the side surface of the base body 10 as the symmetry plane, the two flow channels 20 on both sides of the base body 10 are symmetrically arranged with respect to this middle surface. The cross-section of the flow channel 20 is square, and the flow channel 20 is integrally bent in an S-shaped trend. Two through openings 30 are provided on one side of the base body 10, the positions of the two through openings 30 respectively correspond to the positions of the ends of the two flow channels 20, and buffer cavities 21 are respectively provided at the positions between the two through openings 30 and the corresponding ends of the flow channels 20. The buffer cavities 21 communicate the two through openings 30 with the corresponding ends of the flow channels 20, and at the same time, also communicate the corresponding ends of the two flow channels 20. The buffer cavities 21 penetrate through the base body 0, and cover plates 11 are hermetically installed on both sides of the base body 10. The cover plates 11 are single-sided brazing aluminum plates, and the side close to the base body 10 is a brazing solder layer. The two cover plates 11 respectively seal both sides of the buffer cavity 21. At the same time, the two cover plates 11 respectively seal the flow channels 20 on both sides of the base body 10, so that one side of the flow channel 20 is sealed, ensuring that the cold liquid in the flow channel 20 will not leak out. At the same time, it is also convenient for processing and manufacturing, and improves production efficiency.

[0025] Among them, the flow channel 20 includes four straight sections 40 and three arc sections 41. The multiple straight sections 40 are arranged parallel to each other. The inner side wall of the arc section 41 is an arc surface, and both side surfaces of the arc section 41 are also arc surfaces. Two adjacent straight sections 40 are connected through an arc section 41 at the same end, thereby forming a smooth flow channel 20. A straight partition 51 is integrally formed and protruded on the bottom wall of the straight section 40, and the top surface of the straight partition 51 is flush with the side surface of the base body 10. An arc partition 52 is integrally formed and protruded on the bottom wall of the arc section 41, and the top surface of the arc partition 52 is flush with the side surface of the base body 10. Two straight partitions 51 on two adjacent straight sections 40 are connected through the arc partition 52, so that the four straight partitions 51 and the three arc partitions 52 form a smooth total partition 50. The total partition 50 is bent as a whole in an S-shaped trend, so that the total partition 50 adapts to the internal space of the flow channel 20. In this embodiment, there are two total partitions 50 arranged side by side, and the distance between two adjacent total partitions 50 is the same as the distance between the total partition 50 and the side wall of the flow channel 20. That is to say, the total partition 50 divides the flow channel 20 into three channels with the same width. At the same time, the width of the total partition 50 is the same as the distance between two side walls of two adjacent straight sections 40 that are close to each other, so that each channel formed by the flow channel 20 in the straight section 40 is evenly distributed, so as to improve the balance of water-cooled heat dissipation.

[0026] Devices that need to be cooled can be respectively attached to both sides of the water-cooled plate in this embodiment. The cold liquid flows through the flow channel 20 through two through ports 30. The cold liquid is shunted into two flow channels 20 in the buffer cavity 21. Each flow channel 20 is shunted into multiple channels through the total partition 50 and flows independently. When the cold liquid passes through the arc section 41, the arc transition of the arc section 41 can be used to improve the cooling effect at the inflection point position. At the same time, the flow channel resistance is reduced to the lowest, so as to further improve the cooling effect and realize the use of two or more water-cooled pipes in series or parallel.

[0027] In other embodiments, the positions of the two flow channels 20 on both sides of the base body 10 and the position of the total partition 50 can be set to stagger a certain distance, such as staggering the size of the width of a total partition 50, so that the cold liquid flow paths of the two flow channels 20 are staggered from each other, so as to give full play to the heat dissipation effects of the two flow channels 20.

[0028] In other embodiments, the number of straight sections 40 can also be set to three, five, six, etc., and the number of arc sections 41 is one less than the number of straight sections 40. And if the number of straight sections 40 is an even number, the positions of the two through ports are at the same end position of the base body 10, and if the number of straight sections 40 is an odd number, the positions of the two through ports are respectively at both ends of the base body 10.

[0029] A groove 60 is provided at the end of the flow channel 20, and the groove 60 makes the end of the flow channel 20 stepped. The two grooves 60 corresponding to the same end of the two flow channels 20 are respectively on the side walls close to each other. The surface of the groove 60 parallel to the corresponding end face of the flow channel 20 is the resisting surface 61. The resisting surface 61 is perpendicular to the plane where the flow channel 20 is located, and at the same time, the resisting surface 61 is perpendicular to the flow direction of the cold liquid here. When the cold liquid enters the flow channel 20 from the buffer chamber 21, it will be resisted by the end face of the flow channel 20 and the resisting surface 61 and flow towards the corresponding side cover plate 11, so as to keep the full contact between the cold liquid and the cover plate 11 and improve the heat exchange efficiency.

[0030] Arc-shaped surfaces 22 are provided on the side walls of the two buffer chambers 21 close to each other. The arc-shaped surfaces 22 are close to the arc segment 41 in the middle, and the arc-shaped surfaces 22 are adapted to the outer shape of the arc segment 41 in the middle, so that the distance between the side walls of the buffer chamber 21 and the arc segment 41 in the middle close to each other is small, so as to give full play to the heat dissipation effect of the cold liquid.

[0031] The width of the straight partition 51 is slightly larger than the width of the arc-shaped partition 52 connected to it. The straight partition 51 with different widths and the corresponding arc-shaped partition 52 are connected by an arc surface transition. And in the same arc segment 41, the width of the arc-shaped partition 52 with a larger radius is smaller than the width of the arc-shaped partition 52 with a smaller radius. In the same arc segment 41, concave transition surfaces are provided at both ends of the side wall with a larger radius in the flow channel formed by being separated by the arc-shaped partition 52 to adapt to the width change from the straight partition 51 to the arc-shaped partition 52. At the same time, when the cold liquid enters the arc segment 41, the flow rate can be slowed down and the resistance can be reduced. In addition, guiding inclined surfaces 70 are provided on both sides of both ends of the total partition 50. It is used to guide the cold liquid to splash into the direct current section 40, further reducing the flow resistance of the cold liquid.

[0032] The embodiments of the present invention have been described in detail above with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can also be made without departing from the purpose of the present invention.
