Description

Technical Field

[0001] The present invention relates to the technical field of automobile thermal module installation equipment, and in particular to a water-side thermal management module installation bracket. Background Art

[0002] As consumers' demands for automotive comfort become increasingly higher, higher requirements are being placed on the vehicle's NVH performance, especially in new energy vehicles. Whether it is the battery or the motor, a large amount of heat is generated during high-speed driving. In addition to the traditional cooling system module for cooling, a water-side thermal management module has now been added. In the battery thermal management of electric vehicles, the thermal management water-side integrated module can achieve rapid cooling and heating of the battery by controlling the switching between different fluid pathways, thereby improving the battery life and performance. In addition, in the motor thermal management of electric vehicles, the thermal management water-side integration can also achieve rapid cooling and heating of the motor by controlling the switching between different fluid pathways, thereby improving the motor's efficiency and output power.

[0003] The water-side thermal management module is generally installed in the front cabin of the car. When the thermal management module is working, its motor will generate a certain amount of excitation. If the dynamic stiffness of the installation point is insufficient, the vibration isolation effect will be poor. The excitation generated by the motor can easily be transmitted to the interior of the car's driving cabin, affecting the NVH performance of the entire vehicle and directly affecting the driving experience and evaluation of the driver and passengers. Therefore, it is particularly important to design a small-sized, easy-to-install, and high-performance mounting point reinforcement bracket.

[0004] For example, announcement number N219769638U, dated September 29, 2023, discloses a mounting bracket for a thermal management module, a thermal management module, and a vehicle. The mounting bracket includes a connecting portion and a piping portion. The connecting portion includes a mounting surface for mounting a heat exchanger, a first opening for receiving coolant from the heat exchanger, and a second opening for delivering coolant to the heat exchanger. The piping portion includes a pipeline connected to the first opening and the second opening, and a valve seat connected to the pipeline and for receiving the valve body of a flow control valve. The aforementioned mounting bracket has a complex structure, high manufacturing cost, is not convenient for rapid installation of the thermal management module, is not convenient for maintenance of the thermal management module, and has poor practicality. Summary of the Invention
