[0001] This utility model relates to the field of battery cooling technology, specifically a liquid cooling plate for energy storage batteries. Background Technology

[0002] Energy storage batteries can achieve the effect of storing electricity by utilizing their internal energy storage structure. However, in some applications of energy storage batteries, there is the problem of long-term charging and discharging, which leads to an increase in internal temperature. To avoid this situation, liquid cooling plates are required. The internal coolant circulates through a U-shaped loop to cool the energy storage battery.

[0003] In existing technologies, the connection structure between the coolant inlet and outlet of the liquid cooling plate is usually fixed by welding, which makes it impossible to disassemble when deformation, damage or breakage occurs. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a liquid cooling plate for energy storage batteries, including a cooling top cover plate, wherein a splicing assembly is provided on the outer side of the cooling top cover plate, and the splicing assembly is used for quick splicing to assist separation for internal maintenance; a quick installation assembly is provided at the bottom of the right end of the cooling top cover plate, and the quick installation assembly is used for installing and disassembling the coolant connection structure.

[0006] The splicing component includes a first limiting frame, and a second limiting frame is provided on the right side of the first limiting frame. A knob post is provided on the front and back of the second limiting frame, and a threaded post is installed on the left side of the knob post. A fixing screw sleeve is installed on the front and back of the first limiting frame, and the fixing screw sleeve is located outside the threaded post.

[0007] The quick-installation assembly includes a connecting sleeve, and a combination screw sleeve is installed on the top of the connecting sleeve. A fixing plate is installed on the outer side of the upper end of the connecting sleeve, and four sets of fastening knobs are embedded in the outer ring of the fixing plate. A locking screw head is provided on the top of the fastening knob.

[0008] Preferably, the outer ring of the cooling cover plate is equipped with a combined edge, and a sealing gasket is provided at the bottom of the combined edge.

[0009] Preferably, the top and bottom of the sealing gasket are fitted with limit rings, and the bottom of the sealing gasket is provided with a cooling cover plate.

[0010] Preferably, the inner sides of the first limiting frame and the second limiting frame are provided with a combination groove, and the combination groove is located on the outer side of the combination edge and the edge of the cooling lower cover plate.

[0011] Preferably, a combined bearing is provided on the outer side of both ends of the knob post, and a fixing ring is provided on the outer side of the combined bearing. The fixing ring is located on the front and back of the second limiting frame.

[0012] Preferably, the bottom of the connecting sleeve is provided with a connecting pipe, and the top of the fixing plate is equipped with a sealing ring, and the sealing ring is located at the bottom of the liquid inlet / outlet hole on the right end of the cooling lower cover plate.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] First, this utility model, by installing a splicing component, can directly connect and install with the pre-drilled screw hole at the bottom of the cooling lower cover plate using a combination screw sleeve. After installation, the fixing plate will squeeze the sealing ring, thereby increasing the sealing performance through compression. While maintaining tight compression, the locking screw head can be extended by controlling the tightening knob. After extension, it will contact the bottom of the cooling lower cover plate, increasing friction. By setting the splicing component, the problem of existing coolant inlet and outlet pipes being unable to be disassembled and repaired can be effectively solved.

[0015] Secondly, this utility model, by installing a quick-installation component, addresses the issue that existing liquid cooling plates are fixed at the edges by welding, making structural separation impossible and inconvenient for subsequent maintenance. By setting a first limiting frame and a second limiting frame, the plate can be directly restricted to the outside of the combined edge via the side. The threaded column can be rotated by using a knob column, and during the rotation, it contacts the fixing screw sleeve, achieving a tightening effect through rotation. The quick-installation component allows for the rapid disassembly and separation of the cooling upper cover plate and the cooling lower cover plate, facilitating maintenance.

[0026] Through the above technical solution, the combined screw sleeve 302 can be directly connected and installed to the screw hole reserved at the bottom of the cooling lower cover plate 104. After installation, the fixing plate 303 will squeeze the sealing ring 304. The sealing performance can be increased by squeezing. While maintaining tight compression, the locking screw head 306 can be extended by controlling the fastening knob 305. After extension, it will contact the bottom of the cooling lower cover plate 104 to increase friction. By setting the splicing component, the problem that the existing coolant inlet and outlet pipes cannot be disassembled and repaired can be effectively solved.

[0027] With the above technical solution, by setting the first limiting frame 2 and the second limiting frame 202, the outer side of the combined edge 101 can be directly restricted by the side. The screw post 206 can be rotated by the knob post 205. During the rotation, it contacts the fixing screw sleeve 201. The tightening effect can be achieved by rotating. The cooling upper cover plate 1 and cooling lower cover plate 104 can be quickly disassembled and separated by quick installation components, which is convenient for maintenance.

[0028] Specifically, the outer ring of the cooling top cover 1 is equipped with a combined edge 101, and a sealing gasket 102 is provided at the bottom of the combined edge 101.

[0029] Through the above technical solution, the combined edge 101 can be combined with the bottom sealing gasket 102 and the cooling lower cover plate 104 to achieve a sealing effect.

[0030] Specifically, limit rings 103 are installed at the top and bottom of the sealing gasket 102, and a cooling lower cover plate 104 is provided at the bottom of the sealing gasket 102.

[0031] Through the above technical solution, the limiting ring 103 can increase the sealing performance after assembly, and grooves are provided on the inner side of the edges of the upper cooling cover plate 1 and the lower cooling cover plate 104, which correspond exactly to the limiting ring 103.

[0037] Through the above technical solution, the connecting pipe 3 can be connected to the external coolant pipe, and the sealing ring 304 can increase the sealing performance by compression.

[0038] During use, the sealing gasket 102 is first placed between the combined edge 101 and the cooling lower cover plate 104 during assembly. After compression, the first limiting frame 2 and the second limiting frame 202 are slidably assembled from the side. After assembly, the connecting sleeve 301 can be tightened by rotating the control knob 205 and using the threaded column 206. During assembly, the sealing gasket 102 held in the middle will be in a state of compression deformation to maintain the seal. Then, the combined threaded sleeve 302 is installed inside the threaded groove at the bottom of the right end of the cooling lower cover plate 104. After continuously rotating the installation to keep the sealing ring 304 compressed, the tightening knob 305 is adjusted again to control the locking screw head 306 to compress and achieve the locking effect.
