Detailed Description

The technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments, and all other embodiments obtained by those skilled in the art without making creative efforts based on the embodiments of the present utility model are included in the protection scope of the present utility model.

Referring to fig. 1-4, the present utility model provides a technical solution:

the high-heat-dissipation battery box comprises a box body 1, wherein a placement frame 2 is connected with the inner buckle of the box body 1, the placement frame 2 is formed by stacking at least 2 layers of frames 21, the number of the layers of frames 21 can be flexibly increased according to the number of batteries, and the design requirements of battery boxes with different specifications are met; and two adjacent shelves 21 are fixed through a pin shaft 22, so that the connection stability between the shelves 21 is improved; the battery grooves 23 are symmetrically formed in the surface of the layer rack 21 at equal intervals, so that the battery is convenient to mount and clamp, the wrapping property of the battery 9 is improved, and the heat of the battery 9 is ensured to be rapidly and fully conducted out; the box body 1 and the layer rack 21 are made of high heat conduction aluminum alloy materials, so that the heat conduction efficiency is ensured, and the heat dissipation performance of the battery box is improved; the opening side fixedly connected with end cover 3 of box 1, the bottom equidistance fixedly connected with radiating fin 4 of box 1, the one end fixedly connected with radiator fan 5 of end cover 3 is kept away from to box 1, and radiator fan 5's air outlet 6 is faced radiating fin 4, realizes the forced air cooling heat dissipation, improves radiating fin 4 heat exchange efficiency, and the heat dispersion is good.

In this embodiment, heat conduction silicone grease is filled between the placement frame 2 and the box 1, so that a gap between the placement frame 2 and the box 1 is eliminated, and heat conduction efficiency between the placement frame 2 and the box is ensured.

In this embodiment, referring to fig. 2, a clamping groove 7 is formed in the center of the end cover 3, so that the connection port 10 is convenient to mount in a clamping manner.
