Abstract
The utility model provides an water cooling type lithium battery module cooling system. The water cooling type lithium battery module cooling system comprises a battery pack with cooling channels, and is characterized in that a cooling pipe is arranged in each cooling channel, one ends of the cooling pipes are connected with the output end of a water pump after being converged, the other ends of the cooling pipes are connected with the input end of a heat radiator after being converged, the output end of the heat radiator is connected with the input end of the water pump, a temperature sensor is arranged on a pipeline between the cooling pipes and the heat radiator, the temperature sensor is connected with a controller, and the controller is connected with the water pump and the heat radiator. As the cooling system provided by the utility model adopts a water cooling manner to cool the battery pack, thereby being good in cooling effect and more uniform in heat radiation; at the same time, due to the water-cooling manner, the battery pack can be sealed in a space so as to prevent the phenomenon that the battery pack is damaged because of water entering; and furthermore, after the cooling system is adopted, the use range of the vehicle with a battery driving system is enlarged.
Description
Technical field
The utility model relates to a kind of system that battery modules is cooled off.
Background technology
Along with the day of traditional energy is becoming tight and the deterioration day by day of environment, each state of the whole world is all greatly developing new-energy automobile.At present, the direction of countries in the world (comprising China) development new-energy automobile mainly concentrates on hybrid vehicle and the pure electric automobile.And battery pack is the topmost parts of hybrid vehicle and pure electric automobile.
At present, air-cooled for the many employings of the cooling of battery pack, promptly adopt fan with the battery pack blast-cold.Adopt this type of cooling to have following shortcoming: if the design of first wind field is unreasonable, then can cause the battery pack cooling temperature field inhomogeneous, radiating effect is poor, thereby influences the result of use of battery pack, quickens the performance degradation of battery pack; The second, can't seal battery pack, if battery pack is installed in automobile bottom, then battery pack is intake easily, has a strong impact on thereby battery pack caused.
Summary of the invention
The purpose of the utility model provides a kind of good cooling results and dispels the heat and is used for the cooling system of battery pack uniformly.The further purpose of the utility model is to make battery pack can be sealed in the space.
In order to achieve the above object; The technical scheme of the utility model has provided a kind of water-cooled lithium battery module cooling system, comprises the battery pack with cooling duct, it is characterized in that: in each cooling duct, be provided with a cooling water pipe; One end of cooling water pipe converges the back and links to each other with the output of water pump; The other end of cooling water pipe converges the input that the back connects radiator, and the output of radiator links to each other with the input of water pump, on the pipeline between cooling water pipe and the radiator, is provided with temperature sensor; Temperature sensor connects controller, and controller links to each other with water pump and radiator.
Preferably, on the pipeline between said water pump and the said cooling water pipe, be provided with heater, heater connects said controller.
Preferably, on the pipeline between said cooling water pipe and the said radiator, be provided with bypass valve and pressure sensor, the bypass valve pipeline connects the input of said water pump, and pressure sensor connects said controller, and controller links to each other with bypass valve.
Preferably, said battery pack places in the sealing box body.
The utility model adopts the mode of water-cooled that battery pack is cooled off, good cooling results not only, and also heat radiation is more even.Simultaneously, owing to be water-cooling pattern, therefore, battery pack can be sealed in the space, prevents that the battery pack water inlet is impaired.More a step, behind employing the utility model, enlarged the scope of application that has the battery powered system vehicle.

Embodiment
For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
In conjunction with Fig. 1 to Fig. 3, a kind of water-cooled lithium battery module cooling system that the utility model provides comprises the battery pack 1 with cooling duct 2, and battery pack 1 places in the sealing box body.In each cooling duct 2, be provided with a cooling water pipe, an end of cooling water pipe converges the back and links to each other with the output of water pump 3, and the other end of cooling water pipe converges the input that the back connects radiator 4, and the output of radiator 4 links to each other with the input of water pump 3.On the pipeline between water pump 3 and the cooling water pipe, be provided with heater 5.On the pipeline between cooling water pipe and the radiator 4, be provided with temperature sensor 7, bypass valve 6 and pressure sensor.Bypass valve 6 pipelines connect the input of water pump 3.Temperature sensor 7 and pressure sensor connect controller, and controller links to each other with water pump 3, radiator 4, heater 5 and bypass valve 6.
The working temperature of every battery is more than 25 degree in the battery pack 1, and in the China north, temperature may reach below-25 ℃, and battery pack 1 just can't operate as normal like this, causes pure electric automobile normally to start.Therefore, in the utility model, increase heater 5, cooling fluid has been heated, battery pack 1 has been carried out preheating, made battery pack 1 can reach working temperature.
Simultaneously, the effect of the bypass valve in the utility model 6 is: open when system pressure surpasses set point that system pressure is too high to cause danger to avoid.
