As shown in fig. 1 to 3, the present disclosure provides a heat dissipation system for a storage battery, including a storage battery 1, an air guide tube 2 and an air intake manifold 3 of an engine, an air outlet 22 of the air guide tube 2 is communicated with the air intake manifold 3, an air inlet 21 of the air guide tube 2 faces the storage battery 1, a switch valve 4 is disposed in the air guide tube 2, when the switch valve 4 is opened, the air guide tube 2 is communicated with the air intake manifold 3, so that the air intake manifold 3 sucks gas around the storage battery 1 through the air guide tube 2, and when the switch valve 4 is closed, the switch valve 4 cuts off the communication between the air guide tube 2 and the air intake manifold 3.

Here, the intake manifold 3 is an important component of an intake system of the engine, the intake manifold 3 is an intake pipe located after a throttle body of the engine and before a cylinder head intake port, and the intake manifold 3 functions to distribute external air or internal fuel mixture of the engine from the throttle body to the cylinder intake ports, so that the engine takes in air through the intake manifold when the engine is in operation. Because the air guide pipe 2 is selectively communicated with the intake manifold 3 in the disclosure, when the air guide pipe 2 is communicated with the intake manifold 3, the gas around the storage battery 1 can be sucked into the engine along the air guide pipe 2 and the intake manifold 3 under the driving of the power of the engine.

According to the technical scheme, the air outlet 22 of the air guide pipe 2 is communicated with the air inlet manifold 3, the air inlet 21 of the air guide pipe 2 faces the storage battery 1, when the switch valve 4 is opened, the air guide pipe 2 is communicated with the air inlet manifold 3, and the air inlet manifold 3 can suck high-temperature gas around the storage battery 1 through the air guide pipe 2, so that the ambient temperature around the storage battery 1 is reduced, the temperature of the storage battery 1 is further reduced, the effect of heat dissipation of the storage battery 1 is achieved, the risk of heat damage of the storage battery 1 due to overhigh ambient temperature is reduced, the situation that the storage battery 1 is damaged, loses efficacy and even spontaneously combusts is avoided, and the running safety of a vehicle and the safety of personnel in; when the switch valve 4 is closed, the communication between the air guide pipe 2 and the intake manifold 3 is cut off, so that the storage battery 1 can work in a proper working temperature range, and the temperature of the storage battery 1 is prevented from being influenced by excessive heat dissipation.

In one embodiment provided by the present disclosure, the diameter of the air inlet 21 is greater than the diameter of the air outlet 22. Because the air inlet 21 is towards the battery 1, the air outlet 22 is communicated with the air inlet manifold 3, so that on one hand, the flow velocity of the gas flowing from the air inlet 21 to the air outlet 22 can be accelerated, the heat dissipation speed of the battery 1 is accelerated, and the heat dissipation effect of the battery 1 is improved, on the other hand, the diameter of the air inlet 21 can be increased as much as possible, the air suction range of the air inlet 21 is improved, and the heat dissipation speed and the heat dissipation effect of the battery 1 are further improved.

Further, the cross-sectional area of the air guide duct 2 gradually decreases along the gas flow direction a inside the air guide duct 2. The gas flowing direction a in the air guide pipe 2 is a direction in which the gas flows from the gas inlet 21 to the gas outlet 22, the cross-sectional area of the air guide pipe 2 gradually decreases along the gas flowing direction a in the air guide pipe 2, so that the flow speed of the gas in the air guide pipe 2 can be gradually increased, and the phenomena of abrupt structural change and stress concentration of the air guide pipe 2 in the direction from the gas inlet 21 to the gas outlet 22 are avoided.

As shown in fig. 1, in order to make the air guide duct 2 absorb as much high-temperature gas around the battery 1 as possible, in one embodiment of the present disclosure, a projection of the battery 1 on the air inlet 21 is located inside the air inlet 21. That is, the cross-sectional area of the air inlet 21 is larger than the projected area of the battery 1 on the air inlet 21, so that the air inlet 21 can completely cover the battery 1, thereby sufficiently sucking high-temperature gas around the battery 1, and further, the heat dissipation effect of the battery 1 can be more effectively improved.

Here, the bracket 51 may be mounted on the battery base 5 by means of screwing, welding, clamping, or the like, or may be integrally formed with the battery base 5, which is not limited in this disclosure.

The switch valve 4 may be disposed at any suitable position within the air duct 2, and in an exemplary embodiment provided by the present disclosure, the switch valve 4 is disposed at the air outlet 22 to reduce the resistance of the switch valve 4 to the gas flowing within the air duct 2. In other embodiments, the switch valve may be disposed at the air inlet, or disposed in the air duct between the air inlet and the air outlet.

In one embodiment provided by the present disclosure, as shown in fig. 1, the switch valve 4 is an electromagnetic switch valve, the battery heat dissipation system further includes a controller 6 and a temperature sensor 11 disposed on the battery 1, the controller 6 is electrically connected to the switch valve 4 and the temperature sensor 11, the temperature sensor 11 is configured to detect temperature information of the battery 1, and the controller 6 is configured to control the switch valve 4 according to the temperature information of the battery 1. Here, the temperature information of the storage battery 1 may be, for example, a temperature value of the storage battery 1, and the controller 6 may control the opening and closing of the on-off valve 4 according to the received temperature value of the storage battery 1, so as to radiate heat from the storage battery 1 according to the temperature condition of the storage battery 1.

Specifically, when the temperature value of the storage battery 1 detected by the temperature sensor 11 received by the controller 6 is greater than a preset temperature value, the controller 6 may control the on-off valve 4 to open, so that the intake manifold 3 may suck high-temperature gas around the storage battery 1, thereby dissipating heat and cooling the storage battery 1; when the temperature value of the storage battery 1 detected by the temperature sensor 11 received by the controller 6 is lower than the preset temperature value, the controller 6 can control the switch valve 4 to close, so that the heat dissipation of the storage battery 1 is stopped, and the temperature of the storage battery 1 can be kept within the proper working temperature range. Here, the preset temperature value may be an ultimate operating temperature value of the storage battery 1, and for example, the preset temperature value may be 75 ℃.

More specifically, to avoid frequent opening and closing of the on-off valve 4, the battery heat dissipation system may further include a timing module (not shown) electrically connected to the controller 6 and the temperature sensor 11, so that when the temperature value of the battery 1 is greater than the preset temperature value and lasts for the preset time period, the controller 6 may control the on-off valve 4 to open to dissipate heat of the battery 1; when the temperature value of the storage battery 1 is lower than the preset temperature value and lasts for the preset time, the controller 6 can control the switch valve 4 to close so as to stop radiating the storage battery 1. Here, the preset time period may be 30 minutes, 20 minutes, etc., and the present disclosure does not limit this.

In order to improve the accuracy of the temperature information of the battery 1 detected by the temperature sensor 11, in one embodiment provided by the present disclosure, as shown in fig. 1, the temperature sensor 11 is disposed on an electrode of the battery 1, for example, on a positive electrode and/or a negative electrode of the battery 1.

Because the engine is at high temperature during operation, the rising temperature is fast, the steam of production can be to around the battery 1, consequently, the one side temperature value that battery 1 is close to the engine can be higher than the temperature value of one side that battery 1 keeps away from the engine, consequently, also set up temperature sensor 11 in one side that battery 1 is close to the engine, can detect the temperature information of battery 1 more comprehensively, thereby make controller 6 can control switch valve 4 more accurately and open and carry out the cooling of dispelling the heat to battery 1, and then improved the heat dissipation protection effect to battery 1.
