Description

Technical Field

[0001] The utility model relates to the technical field of battery packs, in particular to an air-cooled battery pack with a convex top. Background Art

[0002] Battery packs play a key role in storing and supplying power in electronic devices. They are typically composed of multiple battery cells connected in series or parallel to form a larger battery pack to meet the power and voltage requirements of the device.

[0003] The battery pack generates heat during charging or use. The heat generated will increase the internal temperature, which will affect the efficiency of the battery cells. The battery pack is generally installed in an energy storage cabinet to dissipate heat through the energy storage cabinet. However, since the battery packs are arranged in series in the cabinet, if they are too close together, air cannot enter the battery pack well for heat dissipation. Utility Model Content

[0031] According to some embodiments of the present invention, the top of the upper cover 2 is optionally in a trapezoidal shape, so that a large gap is formed between the upper and lower parts to allow air to circulate.

[0032] According to some embodiments of the present invention, contact plates 12 are optionally provided on both sides of the bottom of the battery pack body 1, and shock-absorbing silicone pads 13 are provided at the bottom of the contact plates 12. In this way, the contact plates 12 and shock-absorbing silicone pads 13 can be used to cushion the battery pack body 1, thereby providing a good shock-absorbing effect and increasing the spacing between the contact plates 12 and the shock-absorbing silicone pads 13, so that cool air can enter better and accelerate the cooling speed.

[0033] According to some embodiments of the present invention, optionally, a plurality of cooling fans 11 are provided on the side wall of the battery pack body 1 to accelerate the cooling speed of the battery pack.

[0034] According to some embodiments of the present invention, the battery pack body 1 may optionally be provided with a plurality of heat dissipation holes 14 at one end opposite to the heat dissipation fan 11 to allow hot air to be exhaled and to dissipate heat effectively.

[0035] According to some embodiments of the present invention, the temperature sensing lead 23 is optionally fixed by a buckle 24, which is provided in the top of the upper cover 2. This prevents the temperature sensing lead 23 from getting stuck and falling onto the battery cell, and also facilitates subsequent replacement and installation.
