At the same time, through the design of the connecting cover, the normal temperature air can flow through the inner cavity of the inner capillary, thereby further improving the heat exchange rate of the two air streams.

[0019] 5. The present invention provides a multi-directional auxiliary shock absorbing device for new energy vehicles. After the heat dissipation air flows into the inner cavity of the automobile battery storage compartment, the air pressure in the inner cavity of the automobile battery storage compartment will increase. The air pressure will apply thrust to the elastic rubber bag, causing the elastic rubber bag to produce compressed elastic deformation, and then the heat-dissipated gas can be discharged from the gap between the blocking member and the elastic rubber bag. After the heat dissipation air stops flowing into the automobile battery storage compartment, the elastic rubber bag will produce a reset deformation, and the gap between it and the blocking member will be sealed to prevent foreign impurities or mosquitoes from easily invading the inner cavity of the automobile battery storage compartment and causing damage to the battery assembly, thereby improving the reliability of the structure.
