Description

Technical Field

[0001] The present application relates to the technical field of water cooling plates, and in particular to a water cooling plate that does not require cutting. Background Art

[0002] The water-cooled plate, also known as liquid-cooled plate, water-cooled heat sink, etc., is a component that exchanges heat through liquid cooling, that is, the coolant enters through the inlet of the water-cooled plate, flows in the flow channel, and finally flows out from the outlet, and absorbs the heat emitted by the component and takes it away, thereby achieving the effect of cooling and dissipating the equipment. The assembly and fixing method of the water-cooled plate is usually stir friction welding connection. Stir friction welding has higher welding strength and lower processing difficulty. The water-cooled plate is used in battery packs. The cost compression of battery packs is an important goal of major battery factories, so the water-cooled plate also needs to reduce costs.

[0003] In the related art, the water cooling plate includes an upper cooling plate and a lower cooling plate. The lower cooling plate is provided with a flow channel for the flow of coolant. The upper cooling plate and the lower cooling plate are integrally formed with a cutting plate.

[0004] In order to ensure that the edges of the upper cold plate and the lower cold plate are flush and meet the requirements of stir friction welding, the existing technology often increases the outline dimensions of the upper cold plate and the lower cold plate, and adds a plate cutting step after brazing and before stir friction welding to ensure that the upper cold plate and the lower cold plate are flush. However, adding plate cutting will increase the cost of manufacturing the water-cooled plate. Utility Model Content

[0005] In order to improve the problem of high manufacturing cost of the upper cold plate and the lower cold plate, the present application provides a water-cooling plate that does not require cutting.

[0006] The present application provides a water-cooling plate without cutting, which adopts the following technical solution:

[0007] A water-cooled plate that does not require cutting includes an upper cold plate and a lower cold plate. The upper cold plate and the lower cold plate are provided with positioning structures, and the positioning structures are used to prevent the upper cold plate and the lower cold plate from sliding. The positioning structures include positioning protrusions and positioning grooves. When the positioning protrusions are inserted into the positioning grooves, the upper cold plate is positioned on the lower cold plate.

[0008] By adopting the above technical solution, the positioning protrusion is inserted into the positioning groove, and the groove wall of the positioning groove restricts the positioning protrusion, so that the upper cold plate can be stably located on the lower cold plate, so that the upper cold plate is not easy to move on the lower cold plate, so as to ensure the flushness of the upper cold plate and the lower cold plate, and thus there is no need to provide cutting plates on the upper cold plate and the lower cold plate, thereby reducing the cost of manufacturing the water-cooled plate.

[0009] Optionally, a receiving groove is formed on the upper cold plate.

[0010] By adopting the above technical solution, a receiving groove is formed on the upper cold plate, and the rubber blocking strip is placed in the receiving groove, so that the rubber blocking strip can limit the rubber so that the rubber can be located on the upper cold plate, thereby preventing the rubber from detaching from the upper cold plate when squeezed, resulting in an unreliable fixation of the upper cold plate.

[0011] Optionally, the accommodating groove surrounds the circumference of the upper cold plate.

[0012] By adopting the above technical solution, the accommodating groove is surrounded along the circumference of the upper cold plate, so that the rubber blocking strip can be placed in the accommodating groove, thereby allowing the rubber blocking strip to surround along the circumference of the upper cold plate, so that the rubber blocking strip can limit the rubber in the upper cold plate, further strengthening the limiting ability of the rubber, and preventing the rubber from moving easily when squeezed.

[0013] Optionally, the positioning protrusion is arranged on the upper cold plate, and the positioning groove is arranged on the lower cold plate.

[0014] By adopting the above technical solution, the positioning protrusion is set on the upper cold plate, and the positioning groove is set on the lower cold plate, so that the positioning protrusion can be inserted into the positioning groove, thereby achieving the effect of mutual positioning of the upper cold plate and the lower cold plate; at the same time, no protrusion will be generated on the side of the upper cold plate away from the lower cold plate, so as to facilitate the subsequent fixation of the upper cold plate and avoid a small range of offset or unreliable fixation of the upper cold plate when fixing.

[0015] Optionally, a flow channel is provided on the lower cold plate, a fixing protrusion is provided on the lower cold plate, the fixing protrusion is formed by stamping a positioning groove, and an end surface of the fixing protrusion away from the upper cold plate is higher than or equal to an end surface of the flow channel away from the upper cold plate.

[0016] By adopting the above technical solution, the end face of the fixing protrusion away from the upper cold plate is higher than or equal to the end face of the flow channel away from the upper cold plate, so that the depth of the fixing protrusion is deeper. Since the positioning groove is stamped with the fixing protrusion, the depth of the positioning groove is deeper, so that the positioning protrusion can be inserted into a larger volume of the positioning groove, so that the contact area between the groove wall of the positioning groove and the positioning protrusion is increased, and the positioning protrusion is not easy to detach from the positioning groove, thereby making the upper cold plate and the lower cold plate more secure, and preventing relative slippage between the upper cold plate and the lower cold plate.

[0017] Optionally, there is a gap between the positioning protrusion and the positioning groove.

[0018] By adopting the above technical solution, a gap is provided between the positioning protrusion and the positioning groove, so that the positioning protrusion does not need to be too precise, which can reduce the process accuracy of manufacturing the positioning protrusion, so that the positioning protrusion can be inserted into the positioning groove without interference, avoiding the situation where the positioning protrusion cannot be inserted into the positioning groove due to being too large, thereby greatly reducing the processing difficulty of the positioning protrusion.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. By inserting the positioning protrusion into the positioning groove, the groove wall of the positioning groove restricts the positioning protrusion, so that the upper cold plate can be positioned on the lower cold plate, so that the upper cold plate is not easy to move on the lower cold plate, so as to ensure that the upper cold plate and the lower cold plate are flush, and there is no need to provide cutting plates on the upper cold plate and the lower cold plate, thereby reducing the cost of manufacturing the water-cooled plate.

[0021] 2. The end face of the fixing protrusion away from the upper cold plate is higher than or equal to the end face of the flow channel away from the upper cold plate, so that the depth of the fixing protrusion is deeper. Since the positioning groove is stamped with the fixing protrusion, the depth of the positioning groove is deeper, so that the positioning protrusion can be inserted into a larger volume of the positioning groove, so that the contact area between the groove wall of the positioning groove and the positioning protrusion is increased, and the positioning protrusion is not easy to detach from the positioning groove, thereby making the upper cold plate and the lower cold plate more secure, and preventing relative slip between the upper cold plate and the lower cold plate.

[0027] This embodiment discloses a water-cooling plate without cutting. Figure 1 and Figure 2 A water-cooled plate without cutting comprises an upper cold plate 1 and a lower cold plate 2. A flow channel 21 is stamped on the lower cold plate 2 for coolant to flow.

[0028] Reference Figure 3, a positioning structure 3 is provided on the upper cold plate 1 and the lower cold plate 2, and the positioning structure 3 is used to prevent relative sliding between the upper cold plate 1 and the lower cold plate 2. The positioning structure 3 includes a positioning protrusion 31 and a positioning groove 32. The positioning protrusion 31 is stamped on the upper cold plate 1, and the positioning groove 32 is stamped on the lower cold plate 2. In other embodiments, the positioning protrusion 31 can be stamped on the lower cold plate 2, and the positioning groove 32 is stamped on the upper cold plate 1.

[0029] Reference Figure 3 When the positioning protrusion 31 is inserted into the positioning groove 32, there is a gap between the positioning protrusion 31 and the positioning groove 32, so as to reduce the processing accuracy of the stamping positioning protrusion 31. When the positioning protrusion 31 is inserted into the positioning groove 32, the upper cold plate 1 is fixed on the lower cold plate 2, so that the upper cold plate 1 is not easy to slide on the lower cold plate 2.

[0030] Reference Figure 3 A positioning protrusion 31 is stamped on one side of the upper cold plate 1, and a receiving groove 33 is formed on the other side of the upper cold plate 1. The positioning protrusion 31 surrounds the circumference of the upper cold plate 1, that is, the receiving groove 33 surrounds the circumference of the upper cold plate 1. The receiving groove 33 is for the rubber stopper strip to be placed, so that the rubber stopper strip can limit the rubber.

[0031] Reference Figure 3 A fixing protrusion 34 is stamped on one side of the lower cold plate 2, and a positioning groove 32 is formed on the other side of the lower cold plate 2. The end surface of the fixing protrusion 34 away from the upper cold plate 1 is higher than or equal to the end surface of the flow channel 21 away from the upper cold plate 1.

[0032] The implementation principle of the non-cutting water-cooled plate in the embodiment of the present application is: the upper cold plate 1 and the lower cold plate 2 are positioned relative to each other by inserting the positioning protrusion 31 into the positioning groove 32 .
