[0002] Water-cooled battery cooling plates for new energy vehicles are thermal management components used in electric vehicle power batteries or energy storage batteries. They achieve temperature control of the battery's operating environment through liquid cooling technology. Their core function is to rapidly remove the heat generated during battery operation via fluid conduction, ensuring the battery operates within its optimal temperature range, thereby improving performance, extending lifespan, and reducing safety risks.

[0003] However, in actual installation and use, water-cooled new energy vehicle battery cooling plates are generally directly attached to the bottom of the battery pack housing and in direct contact with the housing. During use, the vibration force transmitted from the bottom of the vehicle will be directly transmitted to the battery cooling plate, which can easily cause resonance and thus lead to abnormal noises when the vehicle is driving. This has shortcomings and makes it inconvenient to provide vibration damping and protection for the bottom of the battery cooling plate.

[0004] Now, a novel water-cooled battery cooling plate for new energy vehicles is proposed to address the aforementioned shortcomings. Utility Model Content
