Referring to fig. 1 to 2, an embodiment of the present utility model provides a circuit protection box of a battery system, including: a case body 1, a fin group 2, a heat source member 3, and a heat conductive member 4. The cartridge body 1 has a sealed cavity. The fin group 2 is disposed on the outer surface of the case body 1. The heat source component 3 is located within the sealed cavity. The heat conducting member 4 is disposed in the sealed cavity, and the heat conducting member 4 is disposed between the heat source component 3 and a portion of the inner wall of the case body 1 corresponding to the fin group 2. The circuit protection box is internally provided with a circuit board, the circuit board is provided with a chip, and the chip can calculate the residual electric quantity of a battery in the battery system. The heat source component 3 may be a chip. The radiating fin group 2 of the circuit protection box of the battery system is arranged on the outer surface of the box body 1, and the heat source component 3 and the part corresponding to the radiating fin group 2 on the inner wall of the box body 1 are provided with heat conducting pieces 4. The heat generated when the heat source part 3 operates is transferred to the inner wall of the case body 1 through the heat conductive member 4 and then is dissipated to the outside through the fin group 2. Since heat is radiated to the outside, the heat source part 3 does not cause the temperature inside the circuit protection box to be excessively high even if it is operated for a long time.
Referring to fig. 1, the fin group 2 includes a plurality of fins 21, each fin 21 is connected to the case body 1, each fin 21 is parallel, and each fin 21 is sequentially spaced apart in a thickness direction. The plurality of sheets 21 arranged at intervals help to dissipate heat to the outside, and avoid excessive heat in the box body 1.
In one possible embodiment, referring to fig. 1 and 2, the case body 1 has a cavity 11, and the fin group 2 is disposed in the cavity 11. The heat conductive member 4 is disposed between the bottom wall 111 of the cavity 11 and the heat source member 3. If the fin group 2 protrudes from the outer surface of the case body 1, the fin group 2 may interfere with surrounding structures, resulting in damage to the fin group 2. The radiating fin group 2 is arranged in the concave cavity 11, the radiating fin group 2 does not protrude out of the outer surface of the box body 1, the occupied space is small, and interference between the radiating fin group 2 and surrounding structures is avoided. The fin group 2 is disposed in the cavity 11 to protect the fin group 2. The bottom wall 111 of the cavity 11 is recessed toward the inside of the cartridge body 1 such that the distance between the bottom wall 111 of the cavity 11 and the heat source member 3 is short. Because the distance between the bottom wall 111 of the concave cavity 11 and the heat source component 3 is relatively short, the heat conduction effect can be achieved only by filling the thinner heat conduction piece 4, the consumption of the heat conduction piece 4 is reduced, and the production cost is reduced.
The radiating fin group 2 does not extend out of the outer surface of the box body 1, so that the box body 1 is in a regular shape, installation of the circuit protection box is facilitated, and meanwhile, when the circuit protection box is installed, the radiating fin group 2 and surrounding structures interfere to cause damage to the radiating fin group 2.
In one possible embodiment, see fig. 1, the cartridge body 1 has a top wall 12 and a peripheral side wall 13. The peripheral side wall 13 is connected to the top wall 12. The top wall 12 is provided with a first opening 121, the peripheral side wall 13 is provided with a second opening 131, the first opening 121 and the second opening 131 are both communicated with the cavity 11, and the first opening 121 and the second opening 131 are connected. The first opening 121 and the second opening 131 are arranged, so that the contact area between the concave cavity 11 and the outside is larger, which is helpful for the heat dissipation of the heat dissipation fin group 2 to the outside.
The cavity 11 comprises a bottom wall 111 and a first side wall 112 facing the second opening 131. The fin group 2 extends from the first side wall 112 to the second opening 131, so that the fin group 2 extends longer and has larger area, which is helpful for heat dissipation of the fin group 2.
The fin group 2 includes a plurality of fins 21, each fin 21 is connected to the bottom wall 111 and the first side wall 112, and the fin 21 is perpendicular to the first side wall 112. The number of the parts where the sheet body 21 of the radiating fin group 2 is connected with the concave cavity 11 is large, and the connecting area is large, so that the radiating fin group 2 is firm in structure and not easy to damage.
In one possible embodiment, referring to fig. 1, the sheet 21 is provided with a relief 211 near the intersection of the top wall 12 and the peripheral side wall 13. The avoiding portion 211 is arranged, so that the sheet 21 is not abrupt near the intersection between the top wall 12 and the peripheral side wall 13, and the sheet 21 is prevented from being damaged due to interference between the sheet 21 and the peripheral structure when the circuit protection box is mounted.
In one possible embodiment, the heat sink assembly 2 and the cartridge body 1 are integrally formed. The integrated forming part has simple production process, reduces the later installation, and saves the economic cost and the time cost. The integrated into one piece spare structure is more firm, can prolong the life of product.
In one possible embodiment, referring to fig. 2, the heat conductive member 4 includes any one of a heat conductive silicone gel, a heat conductive double sided tape, and a heat conductive silicone grease. The heat conducting member 4 is disposed between the heat source component 3 and a portion of the inner wall of the case body 1 corresponding to the heat dissipating fin set 2, and heat generated during operation of the heat source component 3 is transferred to the inner wall of the case body 1 through the heat conducting member 4 and then is dissipated to the outside through the heat dissipating fin set 2.
The foregoing description is only illustrative of the preferred embodiment of the present utility model, and is not to be construed as limiting the utility model, but is to be construed as limiting the utility model to any simple modification, equivalent variation and variation of the above embodiments according to the technical matter of the present utility model without departing from the scope of the utility model.
