Abstract
Description
Technical Field
[0001] This utility model relates to the field of energy storage technology for new energy vehicles, and in particular to a basin-shaped liquid cooling plate. Background Technology
[0002] With the development of the energy storage market, the 587 large-capacity battery cell will not only be used in grid-side energy storage power stations, but may also find wider application in distributed energy storage, industrial and commercial energy storage, and other fields. During operation, the 587 large-capacity battery cell requires a liquid cooling plate for heat dissipation, using antifreeze flowing through internal channels to cool high-heat sources.
[0003] Conventional brazed cold plates all adopt a planar structure. When adapting to the heat dissipation of 587 large battery cells, the contact area is small and the contact thermal resistance is high, resulting in insufficient heat dissipation efficiency. In addition, the flow channel design has great limitations. When the liquid cooling plate absorbs and dissipates heat from inside the battery, it is easy to cause a large temperature difference between the battery cells, which affects the battery operation and has insufficient compatibility. Utility Model Content
[0004] In view of this, the purpose of this utility model is to propose a basin-shaped liquid cooling plate to solve the problem of low heat dissipation efficiency.
[0005] To achieve the above objectives, this utility model provides a basin-shaped liquid cooling plate, including a basin-shaped flat plate and a flow channel plate. The bottom of the basin-shaped flat plate is provided with a mounting groove, and the flow channel plate is attached to the lower side of the basin-shaped flat plate through the mounting groove. A slot is provided on the side of the flow channel plate, and a sealing element is engaged in the slot. One end of the flow channel plate is connected to a connector, and an inlet flow channel, an outlet flow channel, and a confluence channel are provided inside the flow channel plate. The inlet flow channel and the outlet flow channel are connected through the confluence channel.
[0006] A further improvement is that the inlet flow channel includes a first flow channel and a second flow channel, and multiple sets of the second flow channel are provided. The second flow channel is connected to the first flow channel, and the multiple sets of the second flow channel are connected to the confluence channel.
[0007] A further improvement is that a partition block is provided in the first flow channel, the confluence channel, and the outlet flow channel to separate the first flow channel, the confluence channel, and the outlet flow channel into multiple sets of narrow flow channels.
[0008] A further improvement is that the second flow channel has an S-shaped structure.
[0009] A further improvement is that the connector is provided in two sets, corresponding to the inlet and outlet channels of the flow channel plate, respectively.
[0010] A further improvement is that the joint adopts a bent structure and is set to fit the outer wall of the basin-shaped plate.
[0011] The beneficial effects of this utility model are: by using a basin-shaped flat plate to adhere to the side or bottom of the battery cell, it is easier to achieve large-area adhesion with the battery cell, reduce contact thermal resistance, and thus improve heat conduction efficiency.
[0012] By opening an installation groove at the bottom of the basin-shaped plate, the installation between the flow channel plate and the basin-shaped plate is facilitated, and the flow channel plate is positioned and fitted to the underside of the basin-shaped plate, which facilitates subsequent welding and installation, reduces misalignment, and greatly improves the convenience of processing.
[0013] The connector with a bent structure reduces the drilling process required in existing technologies, allowing the connector to be installed close to the outside of the basin-shaped plate, greatly improving the ease of installation. Furthermore, the connector is installed by welding from the bottom, reducing the risk of leakage. Attached Figure Description

[0023] like Figure 1-4 As shown, this embodiment provides a basin-shaped liquid cooling plate, including a basin-shaped flat plate 1 and a flow channel plate 2. The basin-shaped flat plate 1 is formed by stretching a single piece of sheet metal. The bottom of the basin-shaped flat plate 1 has an arc-shaped or planar structure that matches the height of the battery cell surface, allowing the basin-shaped flat plate 1 to fit tightly against the side or bottom of the battery cell, reducing contact thermal resistance and improving heat conduction efficiency. The bottom of the basin-shaped flat plate 1 is provided with a mounting groove 3. The flow channel plate 2 is attached to the underside of the basin-shaped flat plate 1 through the mounting groove 3. The mounting groove 3 allows the flow channel plate 2 to be positioned and engaged on the underside of the basin-shaped flat plate 1, improving the accuracy of placement, facilitating subsequent installation, and reducing misalignment.
[0024] The flow channel plate 2 has a slot 4 on its side, and a sealing element 5 is engaged in the slot 4. The sealing element 5 is a sealing ring to improve the sealing performance of the flow channel plate 2. The flow channel plate 2 is provided with an inlet flow channel 7, an outlet flow channel 8 and a confluence channel 9. The inlet flow channel 7 and the outlet flow channel 8 are connected through the confluence channel 9.
[0025] The inlet channel 7 includes a first channel 10 and a second channel 11. A partition block 12 is provided within the first channel 10, the confluence channel 9, and the outlet channel 8, dividing the first channel 10, the confluence channel 9, and the outlet channel 8 into multiple sets of narrow channels. Multiple sets of the second channel 11 are provided. The narrow channels formed by the partition blocks 12 of the first channel 10 are connected to the corresponding second channels 11. Multiple sets of the second channels 11 are sequentially connected to the confluence channel 9. The second channels 11 have an S-shaped structure. Coolant flows from connector 6 into flow channel plate 2, flows through multiple sets of narrow channels formed by partition blocks 12 in the first flow channel 10, merges into the corresponding second flow channel 11 from the narrow channels of the first flow channel 10, and then merges into the manifold 9 from the second flow channel 11, increasing the flow channel area. The coolant collected in the manifold 9 then enters the outlet flow channel 8, flows through multiple sets of narrow channels formed by partition blocks 12 in the outlet flow channel 8, and converges at connector 6 for discharge. By improving the flow channel structure, the flow of the internal solution is improved, thereby increasing the heat exchange efficiency, reducing the temperature difference, and ensuring that the equipment temperature operates within a safe range.
[0026] One end of the flow channel plate 2 is connected to a connector 6. Two sets of connectors 6 are provided, corresponding to the inlet and outlet flow channels of the flow channel plate 2 respectively. Water enters and exits through the flow channel plate 2 via the connectors 6. The connectors 6 adopt a bent structure and are set to fit against the outer wall of the basin-shaped plate 1. The connectors 6 are set to fit against the outer side of the basin-shaped plate 1, eliminating the drilling installation process in the existing structure and improving the convenience of installation.
[0027] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of this utility model is limited to these examples; within the framework of this utility model, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this utility model as described above, which are not provided in the details for the sake of brevity. Any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
