[0019] In order to facilitate the understanding of those skilled in the art, the utility model is further explained below in combination with examples and drawings, and the content mentioned in the embodiment is not a limitation on the utility model. The utility model is described in detail below in combination with drawings.

[0020] As Figs. 1 to 3 The utility model discloses a novel water cooling plate, including body 1, the body 1 is equipped with several runners 2, the inner top wall and the inner bottom wall of runner 2 are equipped with a plurality of ribs 3 respectively, the rib 3 of inner top wall is misaligned with the rib 3 of inner bottom wall and is set, and the surface of rib 3 is smooth arc structure.

[0021] When actually using, the rib 3 is strip-shaped, and the smooth structure of the surface can effectively increase the contact area with water in the runner 2 and reduce the flow resistance between water and the rib 3; the rib 3 is staggered on each inner top wall and inner bottom wall, so that water in the runner 2 can generate turbulence, and under the action of turbulence, water not only flows in a certain direction at a specific position, but also flows in multiple directions, so that different water has the opportunity to contact the rib 3 and the inner wall of the body 1 to realize heat exchange, thereby improving the heat transfer effect and making the water absorption of heat tend to be uniform.

[0022] In the embodiment, the number of the ribs 3 of the inner top wall is two, and the number of the ribs 3 of the inner bottom wall is three. The projection of the rib 3 of the inner top wall of the body 1 on the inner bottom wall is between the two adjacent ribs 3 of the inner bottom wall. The structure of the two ribs 3 of the inner top wall and the three ribs 3 of the inner bottom wall makes the distribution of the ribs 3 uniform and the density low, thereby reducing the production difficulty while ensuring the heat transfer effect and the uniform temperature effect.

[0023] In the embodiment, the rib 3 comprises a connecting portion 4 and an arc-shaped portion 5, the connecting portion 4 is arranged between the inner top wall / inner bottom wall of the flow channel 2 and the arc-shaped portion 5, the two sides of the connecting portion 4 are respectively concave arcs, and the outer surface of the arc-shaped portion 5 is an arc surface facing away from the connecting portion 4.

[0024] That is, the arcs at different positions of the rib 3 are different, so as to reduce the flow resistance and increase the effect of turbulent flow through different arc radii.

[0025] In the embodiment, the length of the flow channel 2 on the two sides is greater than the length of the other flow channels 2. In the flow channel 2 on the two sides, the length of the rib 3 close to the outer side is greater than the length of the rib 3 close to the inner side.

[0026] Specifically, in the flow channel 2 on the two sides, one end of the rib 3 is provided with an inclined surface 6.

[0027] The flow channels 2 on the two sides are mainly used for external water inlets / outlets. The longer flow channel 2 and the longer rib 3 ensure that the water in the flow channel 2 will generate turbulent flow effect due to the rib 3, thereby ensuring the uniform temperature.

[0028] In the embodiment, the body 1 is a structure with two open ends, and the two open ends are in communication with the flow channels 2. The two open ends are respectively used for assembling the flow guide plates (not shown in the figure).

[0029] Specifically, the body 1 is respectively provided with an assembly groove 7, that is, when the flow guide plate is assembled, the flow guide plate is slidably assembled into the assembly groove 7 and then welded with the body 1. At this time, the flow guide plate can necessarily tightly cover the two open ends of the body 1, thereby ensuring the air tightness of the utility model.

[0030] In the embodiment, the body 1 and the rib 3 are integrally formed, so that the connection between the body 1 and the rib 3 is more firm.
