The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Embodiment 1 referring to fig. 1 and 2, a lithium-ion power battery pack comprises a shell 1 and a through hole 6 formed in the side face of the shell 1, a lithium battery module 2 is arranged in a containing space of the shell 1, the lithium battery module 2 is composed of a plurality of lithium battery monomers, a wire 3 is arranged at a wiring port of the lithium battery module 2, the wire 3 is located above the lithium battery module 2, end plates 4 are arranged on two sides of the shell 1, a circuit plug-in unit is mounted on the end plates 4, an air cooling assembly 5 is embedded on the end plate 4 located on one side, a pipeline group capable of circulating cooling liquid is arranged in an inner cavity of the shell 1 and is arranged in a coil shape, and the temperature inside the whole power battery pack can be rapidly reduced in an air cooling and liquid cooling mode.
When the power battery pack is in a high-temperature environment, the temperature of the pipeline group is also increased under the influence of the temperature, and in order to reduce the temperature of the pipeline group, the existing air cooling component 5 of the power battery pack and the pipeline group through which cooling liquid flows are combined, and the inner side of a gap of the pipeline group is provided with a flow force cooling component which can be positioned at different positions of the pipeline group to implement cooling work.
As shown in fig. 7, the air cooling assembly 5 includes a hollow casing 51, a fan assembly 52 is installed in an inner cavity of the casing 51, and blades of the fan assembly 52 face the lithium battery module 2. The air flow generated during the operation of the fan assembly 52 can contact with the lithium battery module 2, so as to reduce the temperature of the lithium battery module 2 during the charging and discharging processes.
The first blocking net rack 53 and the second blocking net rack 54 are respectively installed at the openings at the two ends of the casing 51 to isolate impurities, the second blocking net rack 54 is located in the space opposite to the fan assembly 52 and the lithium battery module 2, the flow guide frame 55 is arranged on the surface of the second blocking net rack 54 and is in a funnel shape and used for dispersing air flow generated by the operation of the fan assembly 52. The purpose of the flow guiding frame 55 is to uniformly disperse the air flow generated by the operation of the fan assembly 52, so that the air flow is fully contacted with the lithium battery module 2, and the heat dissipation efficiency is improved.
As shown in fig. 3, 5 and 6, the pipe set includes a first circulation pipe 10, a second circulation pipe 11 and a communication pipe 12, which are sequentially connected, where the first circulation pipe 10, the second circulation pipe 11 and the communication pipe 12 are all in a coil-shaped arrangement, and the cooling liquid is easy to reduce the speed of the cooling liquid due to the curved pipe structure in the flowing process of the first circulation pipe 10 and the second circulation pipe 11, so as to sufficiently implement the heat dissipation operation on the lithium battery module 2.
The first communication pipeline 10 and the second communication pipeline 11 are both positioned below the lithium battery module 2, the communication pipe 12 is arranged between the first communication pipeline 10 and the second communication pipeline 11, and the communication pipe 12 is clamped at the outer edge of the flow guiding frame 55. The cooling liquid flowing through the first circulation pipeline 10, the second circulation pipeline 11 and the communication pipe 12 can take away a large amount of heat generated by the operation of the lithium battery module 2 to play a role in heat dissipation. Because the communicating pipe 12 is clamped at the outer edge of the flow guiding frame 55, when the fan assembly 52 operates, the air flow dispersed by the flow guiding frame 55 can pass through the communicating pipe 12 to perform heat dissipation on the pipe body of the communicating pipe 12.

The supporting bar 13 is detachably provided with a plurality of groups of linkage pieces 16, and the linkage pieces 16 are opposite to the bending parts of the pipe bodies of the first circulating pipeline 10 and the second circulating pipeline 11. The purpose of the linkage piece 16 facing the bending part is to rotate under the action of air flow generated by the operation of the fan assembly 52, so that air flow is further generated and is contacted with the pipe bodies of the first circulating pipeline 10 and the second circulating pipeline 11, and the heat dissipation efficiency of the first circulating pipeline 10 and the second circulating pipeline 11 can be effectively improved on the premise that the fan assembly 52 operates. The cooling component is close to different positions of the first circulating pipeline 10 and the second circulating pipeline 11, so that the heat of the pipeline group can be comprehensively dissipated.
As shown in fig. 8 and 9, the linkage 16 includes a rotating shaft 161 detachably mounted on the inner bottom wall of the support bar 13, a sleeve 162 is rotatably connected to the outer side of the rotating shaft 161, and a plurality of follower blades 163 driven to rotate by air flow are circumferentially arranged on the outer surface of the sleeve 162. When the fan assembly 52 is operated, the air flow can pass through the channel on the surface of the supporting bar 13 to contact with the linkage piece 16, the following blades 163 in the linkage piece 16 are arc-shaped, and under the action of the air flow, the rotation displacement can be generated, and the plurality of following blades 163 drive the sleeve 162 to rotate around the rotating shaft 161.

Further, after the temperature of the first circulating pipeline 10 and the second circulating pipeline 11 is reduced, the temperature rising speed of the cooling liquid circulating inside the first circulating pipeline and the second circulating pipeline can be effectively reduced, the cooling efficiency of the cooling liquid in the circulating circulation and cooling processes is improved, and the long-term use of the cooling liquid is facilitated.
As shown in fig. 3 and 5, the flow force cooling assembly further includes a plurality of supporting plates 15 fixed on the top of the supporting bar 13, the supporting plates 15 are propped against the bottom of the lithium battery module 2, the purpose of the supporting plates 15 is to keep the stability of the whole lithium battery module 2, the supporting plates have supporting and positioning effects on the whole lithium battery module 2, the first circulating pipeline 10 and the second circulating pipeline 11 are located below the supporting plates 15 and propped against the supporting plates 15, and liquid cooling work is implemented on the lithium battery module 2.

As shown in fig. 5 and 7, the smaller diameter open end of the guide frame 55 corresponds to the flow port at the center of the surface of the second barrier net frame 54, and forms a channel through which the air flow can pass. When the fan assembly 52 is operated, a part of air flow is still directly directed to the surface of the lithium battery module 2, and the air flow contacts the center of the lithium battery module 2, so that the heat dissipation effect is ensured.
As shown in fig. 6, the outer surfaces of the first and second circulating pipelines 10 and 11 are sleeved with a support 9, two symmetrical supporting legs of the support 9 are fixed on the inner bottom wall of the casing 1, and the purpose of the support 9 is to maintain the stability of the first and second circulating pipelines 10 and 11 and the communication pipe 12 connecting the two pipelines and maintain the balance of the whole pipeline group, so that the pipeline group and the cooling liquid circulating inside the pipeline group can conveniently perform heat dissipation on the lithium battery module 2.
