Description

Technical Field

[0001] This utility model relates to the field of liquid cooling plate technology, and in particular to a liquid cooling plate with a protective structure on its shell. Background Technology

[0002] A liquid cooling plate is a heat exchange device that removes heat through the circulation of coolant. It features a compact structure and high heat dissipation efficiency. In the automotive industry, it is primarily used for battery cooling, enabling precise temperature control to ensure the battery operates at an optimal temperature, extending battery life and improving performance.

[0003] However, in actual vehicle operation, in order to improve heat dissipation, the liquid cooling plate is placed close to the battery. However, the liquid cooling plate is prone to moving up and down within a small range due to the vibration generated by the vehicle's movement, which can directly damage the liquid cooling plate. In addition, the liquid cooling plate itself is affected by the gravity of the battery module, which aggravates the damage to the liquid cooling plate, making it quite inconvenient.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides, for example Figure 1-4 The liquid cooling plate shown has a protective structure in its casing, including an upper cover 1, a lower cover 2, a connecting rod 3, a protective plate 4, a foam board 5, and a snap-fit ​​mechanism 6. The connecting rod 3 is fixedly connected to the bottom end of the lower cover 2 at equal intervals. The top end of the protective plate 4 has connecting grooves at equal intervals that mate with the connecting rod 3, and a groove is formed at the top end of the protective plate 4. The foam board 5 is fixedly installed inside the groove and is used to fit the lower cover 2. The snap-fit ​​mechanism 6 is disposed inside the protective plate 4 and is used for multi-point positioning of the protective plate 4. The snap-fit ​​mechanism 6 installs the protective plate 4 with foam board 5 at the bottom of the liquid cooling plate cover 2. The protective plate 4 provides solid bottom support for the liquid cooling plate, effectively reducing the pressure of the battery module's weight on the liquid cooling plate. The foam board 5 is soft and elastic, and can act as a buffer medium when the vehicle vibrates, reducing the vertical displacement of the liquid cooling plate caused by vibration and avoiding direct damage. The use of the snap-fit ​​mechanism 6 makes the installation and removal of the protective plate 4 convenient, facilitates subsequent maintenance, extends the service life of the liquid cooling plate, and ensures its stable heat dissipation performance.

[0031] Specifically, the snap-fit ​​mechanism 6 includes a pressing plate 61, a pull plate 62, a pull rod 63, a snap-fit ​​rod 64, a fixing plate 65, and a compression spring 66. Both sides of the protective plate 4 have pressing grooves, with the pressing plate 61 located inside the pressing grooves. Both sides of the protective plate 4 have pull grooves, with the pull plate 62 located inside the pull grooves. One end of the pull rod 63 is fixedly connected to the pressing plate 61, and the other end of the pull rod 63 is fixedly connected to the pull plate 62. One end of the snap-fit ​​rod 64 is fixedly connected to the pull plate 62. The outer wall of the connecting rod 3 has a snap-fit ​​hole, and the other end of the snap-fit ​​rod 64 is slidably inserted into the inner cavity of the snap-fit ​​hole. The fixing plate 65 is disposed inside the pressing grooves, and the compression spring 66 is sleeved on the outside of the pull rod 63. One end of the spring 66 is fixedly connected to the fixing plate 65, and the other end of the compression spring 66 is fixedly connected to the extrusion plate 61. The compression spring 66 always provides a stable elastic force to the snap-fit ​​rod 64 through the pull plate 62 on the pull rod 63, so that the snap-fit ​​rod 64 can be stably snapped into the snap-fit ​​hole, thereby stably installing the protective plate 4 at the bottom of the liquid cooling plate cover 2, thus providing good support for the entire liquid cooling plate. At the same time, the foam plate 5 can also be closely attached to the bottom of the liquid cooling plate. The foam can play a role in heat preservation and buffering, effectively reducing the heat exchange between the floating liquid cooling plate and the external environment, and increasing the protection strength of the bottom of the battery pack, reducing the risk of thermal runaway caused by the bottom impact of the battery pack.

[0032] Furthermore, a limiting groove is formed on the inner wall of the groove, and a limiting rod 67 is fixedly connected to the inner wall of the limiting groove. A limiting block 68 is fixedly connected to the top of the fixing plate 65. The limiting block 68 and the limiting rod 67 are slidably inserted into each other. A countersunk hole is formed at the bottom of the protective plate 4, and a bolt 69 is slidably inserted into the inner cavity of the countersunk hole. An installation hole is formed at the bottom of the fixing plate 65, and the bolt 69 passes through the countersunk hole and is threadedly inserted into the inner cavity of the installation hole. The insertion of the limiting block 68 and the limiting rod 67 limits the position of the fixing plate 65, which facilitates the subsequent positioning and installation of the bolt 69. The disassembly and assembly of the fixing plate 65 makes it easy to replace the compression spring 66, thereby extending the service life of the entire device and making it easy to use.

[0033] Furthermore, a limiting plate 610 is fixedly connected to the outer wall of the pull plate 62. The limiting plate 610 is slidably inserted into the inner cavity of the countersunk hole. After installation, the limiting plate 610 can limit the bolt 69 to prevent it from gradually loosening under vibration and affecting the installation effect. This reduces the risk of connection failure between the pull plate 62 and other components due to loose bolt 69, and also reduces additional noise and vibration caused by loose components. At the same time, it ensures the normal operation of the entire device, reduces failures caused by connection problems, reduces maintenance costs and time, improves the reliability and service life of the equipment, and provides a strong guarantee for the long-term stable operation of the equipment.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
