Description

Technical Field

[0001] This utility model belongs to the technical field of liquid cooling plate equipment, specifically relating to an immersion liquid cooling plate with a fixed structure. Background Technology

[0002] Currently, the research and application of battery cell modules are receiving increasing attention. Various devices are placing ever-increasing demands on the energy and power of battery cell modules, leading to a corresponding increase in heat generation. Therefore, to protect battery cell modules from damage and extend their lifespan, numerous cooling structures for battery cell modules have been researched. Existing cooling methods primarily involve placing the battery cell modules on liquid cooling plates for heat dissipation.

[0003] In the prior art, the liquid cooling plates located on both sides of a single battery cell can exchange heat with the cell simultaneously. However, the two adjacent liquid cooling plates are only connected by pipes, which results in poor installation stability of the liquid cooling plates and easily causes the gap between the liquid cooling plates and the battery cells to be too large, reducing the heat exchange efficiency of the liquid cooling plates. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide an immersion liquid cooling plate with a fixed structure. By setting up a liquid cooling plate and a coolant delivery assembly, the battery cell is installed between two adjacent liquid cooling plates. A fixing assembly is also fixedly installed between two adjacent liquid cooling plates. The setting of the fixing assembly makes the installation cavity for the battery cell formed between two adjacent liquid cooling plates, while increasing the stability of the installation between the liquid cooling plates, preventing the liquid cooling plates from shaking, and ensuring the heat exchange efficiency of the liquid cooling plate for the battery cell.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An immersion liquid-cooled plate with a fixed structure includes: a plurality of liquid-cooled plates, with a battery cell disposed between two adjacent liquid-cooled plates; a coolant delivery assembly for supplying coolant to a single liquid-cooled plate and performing circulating heat exchange; and fixing assemblies at both ends of two adjacent liquid-cooled plates, forming a mounting cavity for mounting the battery cell between the two adjacent liquid-cooled plates. Each fixing assembly includes a fixing bracket and a connector, with one end of the connector fixedly connected to the end of the fixing bracket and the other end fixed to the liquid-cooled plate. This invention, by setting up liquid-cooled plates and a coolant delivery assembly, allows the battery cell to be mounted between two adjacent liquid-cooled plates. The fixing assemblies further fix the battery cell between the two adjacent liquid-cooled plates, creating a mounting cavity for the battery cell and increasing the stability of the liquid-cooled plates, preventing them from shaking and ensuring the heat exchange efficiency of the liquid-cooled plates for the battery cell.

[0007] Furthermore, the liquid cooling plate includes a connecting pipe end, a plate body, and a circulation pipe end. The plate body is located between the connecting pipe end and the circulation pipe end, and the connecting pipe end, the plate body, and the circulation pipe end are connected. The connecting pipe end is connected to the coolant delivery assembly. The plate body is installed and fixed between the connecting pipe end and the circulation pipe end. The coolant delivery assembly controls the coolant to be delivered from the upper part of the connecting pipe end into the plate body. After passing through the upper part of the plate body, the coolant flows into the circulation pipe end for circulation, and then is delivered to the lower part of the plate body, and exits from the lower part of the connecting pipe end into the coolant delivery assembly.

[0008] Furthermore, one end of the connector is provided with an arc-shaped clamping part, which abuts against the outer wall of the corresponding connecting pipe end and circulation pipe end. The other end of the connector is provided with a fixing part, which is fixedly connected to the fixing bracket by bolts. The arc-shaped clamping parts abut against two adjacent liquid cooling plates respectively to prevent the liquid cooling plates from shaking and to fix the gap between the liquid cooling plates and the battery cell, preventing the gap from changing and ensuring the heat exchange efficiency of the liquid cooling plates to the battery cell.

[0009] Furthermore, the connecting pipe end has a cavity 1 with openings at both the top and bottom. The end of the connecting pipe near the coolant delivery assembly has a connecting hole that communicates with the coolant delivery assembly. The other end of the connecting pipe has an interface 1 that matches the plate body. The cavity 1, connecting hole, and interface 1 are all connected. The coolant delivery assembly controls the coolant to enter the cavity 1 through the connecting hole and then be delivered into the plate body through the interface 1.

[0010] Furthermore, the circulation pipe end is provided with a cavity two with openings at both the top and bottom, and the end of the circulation pipe end near the plate body is provided with an interface two, which matches the plate body, and the cavity two is connected to the interface two. The coolant in the plate body enters the cavity two of the circulation pipe end, and the circulation pipe end circulates the coolant to the plate body, and the coolant is then transported by the plate body to the coolant delivery assembly.

[0011] Furthermore, plugs are provided at both the upper and lower openings of the connecting pipe and the circulation pipe. Plugs are used to seal cavities one and two.

[0012] Furthermore, the plate body has a cavity three with openings at both ends. Cavities one and two are connected to cavity three. A partition block is provided within cavity three, dividing it into an inlet cavity and an outlet cavity. Spacer blocks are evenly distributed within both the inlet and outlet cavities, creating flow channels for coolant circulation. The separation of cavity three into an inlet and outlet cavity by the partition block, and the evenly distributed spacer blocks within these cavities forming flow channels for coolant circulation, effectively reduces the temperature difference between the inside and outside of the battery cell located between the two liquid cooling plates.

[0013] Furthermore, a partition plate is fixedly connected to the corresponding partition block inside the cavity 1. The partition plate divides the cavity 1 into an inlet buffer chamber and an outlet buffer chamber. The inlet buffer chamber is connected to the inlet chamber, and the outlet buffer chamber is connected to the outlet chamber.

[0014] Furthermore, the coolant delivery assembly includes an inlet pipe and an outlet pipe. The inlet pipe delivers coolant into the liquid cooling plate, and the coolant inside the liquid cooling plate is discharged through the outlet pipe. One end of the inlet pipe has an inlet port, and the other end has a plug. One end of the outlet pipe has an outlet port, and the other end has a plug. Coolant enters the inlet pipe through the inlet port. The plug is used to seal the other end of the inlet pipe, allowing coolant to enter the liquid cooling plate. The plug is used to seal the other end of the outlet pipe, allowing coolant to discharge from the outlet port.

[0015] Furthermore, connecting pipes are evenly distributed on both the inlet and outlet pipes corresponding to the liquid cooling plates. Each connecting pipe has a connector at its end, which connects to a connecting hole, thus connecting the inlet pipe to the inlet buffer chamber and the outlet pipe to the outlet buffer chamber. The inlet pipe delivers coolant into the inlet buffer chamber through the connecting pipe, and the coolant in the outlet buffer chamber is delivered into the outlet pipe through the connecting pipe, thus achieving coolant delivery.

[0016] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0017] This invention incorporates a liquid cooling plate and a coolant delivery assembly. The battery cell is installed between two adjacent liquid cooling plates, and a fixing assembly is also fixedly installed between the two adjacent liquid cooling plates. The fixing assembly creates an installation cavity for the battery cell between the two adjacent liquid cooling plates, while also increasing the stability of the installation between the liquid cooling plates, preventing the liquid cooling plates from shaking, and ensuring the heat exchange efficiency of the liquid cooling plates for the battery cell.

[0018] In this invention, one end of the connector is provided with an arc-shaped clamping part, which abuts against the outer wall of the corresponding connecting pipe end and circulation pipe end. The other end of the connector is provided with a fixing part, which is fixedly connected to the fixing bracket by bolts. The arc-shaped clamping parts abut against two adjacent liquid cooling plates respectively, preventing the liquid cooling plates from shaking and fixing the gap between the liquid cooling plates and the battery cell, preventing the gap from changing and ensuring the heat exchange efficiency of the liquid cooling plates to the battery cell.

[0019] In this invention, the plate body has a cavity three with openings at both ends. Cavities one and two are connected to cavity three. A partition block is provided within cavity three, dividing it into an inlet cavity and an outlet cavity. Spacer blocks are evenly distributed within both the inlet and outlet cavities, creating flow channels for coolant circulation. The cavity three, divided into an inlet and outlet cavity by partition blocks, and the evenly distributed spacer blocks within these cavities, form flow channels for coolant circulation, effectively reducing the temperature difference between the inside and outside of the battery cell located between two liquid cooling plates.
