Detailed Description
Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
As shown in fig. 1 and fig. 2, the present invention provides a schematic structural diagram of an air cooling system for a battery pack. The air cooling system for the battery pack includes a battery pack 10, a heat exchanging device 20 connected to the battery pack 10, an air pump 30 connected between the battery pack 10 and the heat exchanging device 20, and an air path 40 connected between the battery pack 10, the heat exchanging device 20, and the air pump 30. It is contemplated that the air cooling system for a battery pack may further include other functional modules, such as mounting brackets, assembly components, electrical connection components, etc., which are well known to those skilled in the art and will not be described herein.
The battery pack 10 itself is a prior art battery pack including a plurality of battery packs 11 connected in series or in parallel, and a sealing case 12 covering the outside of the battery packs 11. It is contemplated that each group of battery packs 11 includes a plurality of battery cells, and the battery cells may be connected in series or in parallel, which may be set according to actual needs. The battery piece is the prior art and is not described in detail herein. The sealed housing 12 is typically made of an insulating material, which may be made of a flame retardant material, such as a TVP (thermoplastic vulcanizate) material.
The heat exchange device 20 comprises a housing 21, at least one refrigerant sheet 22 disposed in the housing 21, and at least one filter sheet 23 disposed in the housing 21. The housing 21 should be a sealed housing to prevent heat exchange with the outside or absorb moisture from the outside during operation. The housing 211 has a top cover 211 arranged in a sealing manner. When the top cover 211 is opened, the filter sheet 23 can be replaced because the filter sheet 23 loses its water absorbing capacity after absorbing excessive water, and needs to be replaced. It is of course conceivable that the housing 21 further comprises a fixing structure for fixing the cold-producing sheet 22 and the filter sheet 23, which may be selected according to actual needs, such as screws, bolts, etc., and which will not be described in detail herein, nor shown in the drawings. Additionally, it is contemplated that the housing 21 may include various sealing structures to prevent moisture or heat from entering the housing 21 and causing the heat exchange device 20 to fail. The cooling fins 22 may be water-cooled heat exchange fins, and in order to achieve sufficient cooling, the heat exchange device 20 further includes a cooling device 24, and the cooling device 24 is connected to the cooling fins 22 and is used for converting heat in the cooling fins 22 into the atmosphere. Therefore, the cooling device 24 is disposed outside the casing 21, not inside the casing 21. The refrigeration unit 24 may include a plurality of fins that contain a refrigerant, such as water. For the purpose of circulating the refrigerant, the refrigerating device 24 further includes a micro-circulation pump disposed between the cooling fins and the refrigerating fins 22. The filter sheet 23 is inserted in the housing 21, which may be a honeycomb plate made of a paper material so as to sufficiently absorb water. It is of course conceivable that the honeycomb panel may also include other polymeric water-absorbing materials, such as polyacrylates, polyvinyl alcohols, vinyl acetate copolymers, polyurethanes, polyethylene oxides, starch copolymers, to enhance the water-absorbing properties. When the gas enters the shell 21, the filter sheet 23 can fully absorb the water vapor to the gas, so that the water vapor formed by the gas during the temperature reduction and the water vapor emitted by the gas during the operation of the battery pack 10 are avoided. As shown in fig. 2, in the present embodiment, the heat exchanging device 20 includes a plurality of cooling fins 22 and a plurality of cooling fins 23, and the plurality of cooling fins 22 and the plurality of cooling fins 23 are alternately disposed to perform sufficient heat dissipation and moisture absorption.
