Description

Technical Field

[0001] The present invention relates to the technical field of batteries, and more particularly to a multi-mode high-efficiency heat dissipation battery. Background Art

[0002] A battery is a chemical power source that converts chemical energy directly into electrical energy. Batteries are recharged through a reversible chemical reaction. During charging, electrical energy is stored as chemical energy; during discharge, a chemical reaction occurs within the battery, releasing electrical energy.

[0003] Batteries are common in vehicles, but they are subject to some impact during use. During driving, batteries may be subjected to vibration and impact from the vehicle body, which can damage the battery's internal structure, such as plate deformation and electrolyte leakage. Some batteries also have heat dissipation issues, especially when multiple battery cells are connected in series or parallel. Conventional heat dissipation methods may not provide sufficient heat dissipation. Furthermore, when a battery cell overheats abnormally, targeted heat dissipation cannot be effectively managed, resulting in elevated temperatures and impacting its performance and lifespan.

[0067] Working principle: The battery of the present application has a certain buffering effect because the multiple battery cells are distributed in a rectangular array, and each battery cell is located between the support frame unit and the elastic pressing block, which can achieve better buffering in the use environment.

[0068] Each battery cell is equipped with a temperature sensor at its base, enabling precise monitoring of its temperature. During normal cooling, in the first cooling state, two fan units are located below the two housings. The fan units rotate, causing air to enter the air inlet duct from the connecting hole, pass through the fan units, and then through the space between the base plate and the partitions before being blown upward through the multiple ventilation holes, achieving more uniform cooling for the multiple battery cells. When a battery cell experiences an abnormally high temperature, the two fan units, driven by the rotary drive unit and the multi-stage electric telescopic rod, can be moved. This allows for a second cooling mode. One fan unit (referred to as fan unit A for convenience) is positioned below a vent (located at a corner of the abnormally heated battery cell), while the other fan unit (referred to as fan unit B for convenience) is positioned above the corresponding circular through-hole. Fan unit B draws air from the through-hole and blows it toward the space between the base plate and the partition. Fan unit A dissipates heat from the abnormally heated battery cell. Furthermore, because fan unit B is closer to fan unit A (which primarily provides cooling airflow), it receives more of the cooling airflow from fan unit A, achieving more targeted heat dissipation. The remaining vents also receive the cooling airflow from fan unit A, providing regular heat dissipation. This second cooling mode allows for more targeted heat dissipation of the abnormally heated battery cell.

[0069] Although the present invention has been illustrated and described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
