The utility model has the advantages that: the lithium battery is in contact with the inner surface of the partition board, and the partition board is in contact with the heat conducting layer arranged on the outer surface of the shell, so that the heat of the lithium battery can be directly transferred to the heat conducting layer positioned on the outer side of the shell, and the heat can be directly emitted to the outside; meanwhile, a ventilation grid is arranged on the shell to penetrate through the shell and provide another heat dissipation path, and the heat dissipation effect of the interval type lithium battery protection box is good through the combination of two heat dissipation modes.

Drawings

Fig. 1 is a front view of the compartment-type lithium battery protection box of the present invention.

Detailed Description

The invention will be further explained and explained with reference to the drawings and the embodiments in the following description.

Referring to fig. 1, the embodiment of the present invention provides a compartment type lithium battery protection box, which includes a housing (including a box door 1 and a box body 2), a heat conduction layer 3, a lithium battery 4, a partition plate 5, and a controller 6.

In this embodiment, the box door 1 and the box body 2 are both provided with the attraction portion a, the attraction portion a protrudes outwards and is disposed, each attraction portion a has a concave mounting groove, each mounting groove is provided with a plurality of magnets B, wherein the polarity of the magnet B disposed on the mounting groove of the box door 1 is opposite to the polarity of the magnet B disposed on the mounting groove of the box body 2, so as to attract each other and attract each other when the box door 1 is closed. Simultaneously, because magnet B sets up in the mounting groove, consequently the structure of the mutual lock in outside that has relatively is difficult to receive external environment influence, if receive the corruption, or for a long time use the condition such as deformation wear appears.

The outer surfaces of the box door 1 and the box body 2 are provided with heat conduction layers 3 made of high heat conduction materials, the heat conduction layers 3 can be integrally formed or coated on the outer surfaces of the box door 1 and the box body 2, and the heat conduction layers 3 can be heat conduction glue, heat conduction paste, heat conduction silver glue or a mixture formed by the heat conduction glue and other existing materials and are not limited.
