Background
In the application process of the power battery system, the heating problem is inevitable, and how to dissipate heat becomes an important problem. Because the heat is generated and the dustproof and waterproof are needed, the heat dissipation by using the external air or other heat dissipation media is contradictory to the waterproof and dustproof. The current heat dissipation mode of the battery system mainly comprises: the heat is dissipated through an external air heat dissipation medium, and the air inlet becomes an inlet channel of dust and water mist in the using process, and the dust and the water mist seriously affect the reliability of the battery; the simple heat dissipation mode is that heat is dissipated through a metal shell of the battery combination, but the heat dissipation efficiency of the battery close to the shell in the battery combination is high, and the heat accumulation of the battery far away from the battery shell causes imbalance of the heat in the battery combination, and because the single batteries are different in spatial position of the battery combination, the different thermal environments cause the difference of the functions and the performance of the single batteries, thereby affecting the reliability of the battery system; the heat dissipation is achieved by internal circulation of a heat dissipation medium, which dissipates heat internally by an oily medium or other non-conductive liquid medium, but this way leads to a reduction in the energy density of the battery system.
The existing electric automobile has better advantages than the traditional vehicle in the aspects of energy conservation and emission reduction, but because the whole performance of the electric automobile is restricted by a power battery, and the cycle characteristic of the power battery is closely related to the temperature, the performance of the battery is not favorably exerted when the electric automobile is in actual operation due to overhigh or overlow temperature, and the thermal safety of the battery is further influenced; the existing heat dissipation device can not dissipate heat of the power battery in real time, so that the heat dissipation device continuously works at high power, energy is wasted, excessive loss of the heat dissipation device is caused, and the service life is greatly reduced; accordingly, the invention provides a power battery heat dissipation device.

As an embodiment of the present invention, the diameter value of the end of the air hole 11 close to the power battery is smaller than the diameter value of the end close to the heat dissipation groove 4; the during operation, be less than the diameter value that is close to 4 one ends of radiating groove through the diameter value that is close to power battery one end in with gas pocket 11 for can take out near the hot gas of power battery fast at the in-process that piston plate 9 removed, can push near power battery from gas pocket 11 by force with the gas in the radiating groove 4 when piston plate 9 returns, thereby make the special setting of gas pocket 11 can make the gaseous impact force of pushing stronger, and then realize better radiating effect.
The working principle is as follows: the existing power battery can generate a large amount of heat in the using process, if the heat is not dissipated in time, the service life of the power battery can be greatly influenced, and the existing heat dissipation device can not dissipate the heat of the power battery in real time, so that the heat dissipation device continuously works at high power, the energy is wasted, the excessive loss of the heat dissipation device is also caused, and the service life is greatly reduced; therefore, the power batteries are arranged in the manner of a squared figure by using the partition plates 3, so that the occupied area of the power battery pack is reduced, and the heat dissipation grooves 4 which are reserved among the partition plates 3 can accommodate the heat dissipation pipes 5 and facilitate the circulation of gas at the same time, so that the heat generated by the power batteries during working is taken away; when the battery works, the heat at the crossed position of the heat dissipation grooves 4 is concentrated, so that the horn-shaped end in the air inlet pipe 6 extends out of the lower end of the vehicle to be communicated with the outside by arranging the air inlet pipe 6 communicated with the heat dissipation grooves 4, the horn-shaped end in the air inlet pipe 6 faces the direction consistent with the vehicle advancing direction, generated air flow enters the crossed position of the heat dissipation grooves 4 through the air inlet pipe 6 when the vehicle advances, and then flows into each heat dissipation groove 4, the heat is taken away quickly, the internal air flow is enhanced, and the heat dissipation effect is enhanced; meanwhile, when the wading board passes through the wading surface, redundant water drops can possibly enter the air inlet pipe 6, the raindrop sensor 15 arranged inside the wading board can quickly recognize the water drops and transmit signals to the controller, and the controller immediately controls the electric push rod 8 to stretch out after receiving the information, so that the sealing plate 7 is pushed out, the inside of the air inlet pipe 6 is quickly isolated, the air inlet pipe 6 is not communicated with the heat dissipation groove 4 in the shell 1, and the water drops are prevented from entering the shell 1 to damage the power battery; the power battery can emit heat when the power battery starts to work, when the temperature reaches a standard value set by the temperature sensor, the controller can control the liquid pump to work, so that liquid in the liquid storage box is pumped into the heat dissipation pipe 5, the cooling liquid can absorb the heat in the shell 1 and then returns to the liquid storage box through the output end of the liquid pump, the circulating cooling of the interior of the shell 1 is realized, the continuous high-power work of the heat dissipation pipe 5 is avoided, and the cooling effect is greatly weakened; according to the invention, the air quantity generated in the vehicle traveling process is utilized to guide the air into the heat dissipation groove 4 in the shell 1, so that the interior of the shell 1 is rapidly cooled, and meanwhile, the circulating cooling liquid is introduced by matching with the heat dissipation pipe 5 in the shell, so that the circulating cooling is realized, the heat dissipation efficiency of the power battery is greatly improved, and meanwhile, the power battery is arranged in a manner of a nine-square grid, so that the occupied area of a power battery pack is reduced, and the power battery is more beneficial to the installation of the power battery; meanwhile, when the temperature reaches the set standard, the temperature of the power battery is high, and rapid heat dissipation is needed, at the moment, the interior of the shell 1 needs to be rapidly cooled, and through the induction of the temperature sensor, when the temperature reaches the set standard, except the circulation work of the cooling liquid, the controller controls the motor 13 on one side to work, the motor 13 drives the wind-up roll 12 to rotate clockwise, thereby winding the connected connecting rope 10, pulling the connected piston plate 9 to slide to one side of the winding roller 12, extending the connected spring, and the moving distance of the piston plate 9 is less than the length of the partition plate 3, then the motor 13 drives the winding roller 12 to rotate counterclockwise, thereby the connection rope 10 which is wound is loosened, at this time, the piston plate 9 which is farthest away rebounds rapidly under the action of the self elasticity of the spring, and the piston plate 9 is pulled to return, and the reciprocating is carried out; according to the invention, the reciprocating movement of the piston plate 9 can forcibly extract hot air on the power battery into the heat dissipation groove 4 through the air hole 11, so that the heat exchange between the hot air and the air in the heat dissipation pipe 5 and the air inlet pipe 6 is accelerated, the effect of more rapid cooling is achieved, and the reciprocating movement of the piston plate 9 also greatly accelerates the air flowing speed in the heat dissipation groove 4, so that the heat dissipation efficiency is improved.
