Description
Technical field
The present invention relates to a kind of cooling system of battery, relate in particular to a kind of cooling circulating system of power battery.
Background technology
Along with the development of hybrid power and electric automobile, the capacity of Vehicular accumulator cell is also increasing, and this just needsTo carry out radiating treatment to battery, conventionally all adopt air-cooled form. As Chinese Patent Application No. is200880021548.7 disclosed battery cooling structures, it has: be configured in the baggage room (44) of vehicleBattery (21); The air inlet (24) that contains (42) opening in vehicle chamber, by the air of (42) in vehicle chamberBe supplied to the air inlet pipe (23) of battery (21) as cooling air; And dividing plate (31), itself and back seat are across gapThe vertical setting in ground, marks off (42) in baggage room (44) and vehicle chamber and is formed with that confession air inlet pipe (23) passesPore (36). Form the exhaust of the Bas Discharged in baggage room (44) being arrived to (42) in vehicle chamber at dividing plate (31)Hole (37). Steam vent (37) forms the position separating from pore (36). Adopt such structure, can provideThe cooling structure of the dysgenic battery that a kind of discharge of cooling air having suppressed with temperature rise is accompanied.But the cooling air of this structure just circulates in car, can cause for a long time vehicle interior temperature to raise, reduce passenger and relaxAppropriateness, the load of increase air-conditioning system, uneconomical environmental protection.
Summary of the invention
The object of this invention is to provide a kind of cooling circulating system of power battery, solve current cooling system power consumptionGreatly, the low problem of comfort of passenger.
The technical solution adopted for the present invention to solve the technical problems is: a kind of cooling circulating system of power battery,Comprise the electrokinetic cell of built-in fans, the air inlet pipe that connects electrokinetic cell air inlet and the air-out of connection electrokinetic cellBlast pipe, indoor temperature transmitter and outdoor temperature sensor, the car body control module of mouth. It is characterized in that:On blast pipe, be provided with the first electronic valve with threeway, two outlets of the first electronic valve connect respectively outdoorAir inlet and indoor air inlet, be provided with the second electronic valve with threeway, the second electronic valve on blast pipeTwo outlets connect respectively outdoor exhaust outlet and indoor exhaust mouth; Outdoor air inlet and outdoor exhaust outlet directly connectLead to outside car, indoor air inlet and indoor exhaust mouth are arranged on car room;
Described indoor temperature transmitter and outdoor temperature sensor are respectively by car room temperature and the automobile external worldTemperature is passed to car body control module, if indoor temperature higher than outdoor temperature, car body control module control the first electricitySub-valve, opening chamber's external air inlet mouth, closes indoor air inlet; Car body control module is controlled the second electronics simultaneouslyValve, exhaust outlet in opening chamber, closes outdoor exhaust outlet; If indoor temperature is lower than outdoor temperature, air inletThe opening ways of pipe and blast pipe is contrary.
For removing the peculiar smell bringing when air passes through battery, keep with fresh air in crew module, describedIndoor exhaust mouth end is provided with air purifier.
Preferably, described air inlet and exhaust outlet are separately positioned on the both sides in vehicle chamber.
Further, described indoor air inlet is arranged on back seat hat rack top below; DescribedIndoor exhaust mouth is arranged on back seat below.
Further, temperature signal is passed to sky by described outdoor temperature sensor and indoor temperature transmitterMode transfer piece, Climate Control Module is passed to car body control module by signal again.
Beneficial effect of the present invention: by indoor air inlet, outdoor air inlet and indoor exhaust mouth, chamber are setOuter exhaust outlet, can, according to the height of car room and the outer temperature of car, rationally open air inlet and exhaust outlet,Strengthen indoor occupant's comfortableness, reduce the load of air-conditioning in car, thereby reach reduction oil consumption, save and use intoThis effect, indoor exhaust mouth end is provided with air purifier, can remove air through battery time, bringsPeculiar smell, keep with fresh air in crew module, described indoor exhaust mouth is arranged on back seat below, makesWind can not directly blow to human body, improves comfortableness, and described temperature signal utilizes the resource of existing Climate Control ModuleAgain signal is passed to car body control module, reduce the cost of whole system.
Below with reference to drawings and Examples, the present invention is described in detail.
Brief description of the drawings
Fig. 1 is structure principle chart of the present invention.
Detailed description of the invention
A kind of cooling circulating system of power battery, comprises and connects the electrokinetic cell of built-in fans electrokinetic cell and enterThe blast pipe of the air inlet pipe in air port and connection electrokinetic cell air outlet, indoor temperature transmitter and outdoor temperature passSensor, car body control module, is provided with the first electronic valve with threeway, the first electronic valve on blast pipeTwo outlets connect respectively outdoor air inlet and indoor air inlet, on blast pipe, be provided with the second electricity with threewaySub-valve, two outlets of the second electronic valve connect respectively outdoor exhaust outlet and indoor exhaust mouth; Outdoor air inletMouth and outdoor exhaust outlet are directly communicated to outside car, and indoor air inlet and indoor exhaust mouth are arranged on car room;
Described indoor temperature transmitter and outdoor temperature sensor pass through LIN line respectively by car room temperaturePass to air-conditioning control module with automobile ambient temperature, by air-conditioning control module, temperature signal is being passed to carBody control module, if indoor temperature higher than outdoor temperature, car body control module is by CAN network control firstElectronic valve, opening chamber's external air inlet mouth, closes indoor air inlet; Car body control module is simultaneously by CAN netNetwork control the second electronic valve, exhaust outlet in opening chamber, closes outdoor exhaust outlet; If indoor temperature is lower than chamberOuter temperature, the opening ways of air inlet pipe and blast pipe is contrary. In order to remove, air brings when the batteryPeculiar smell, keeps with fresh air in crew module, is provided with air purifier at described indoor exhaust mouth end. WinterJi Shi, outdoor air inlet, indoor exhaust mouth is opened, and is utilizing cool ambient air to cooling same of electrokinetic cellTime, the hot-air of eliminating can also be used for indoor heating, reduces the load of air-conditioning; In summer, the outer temperature of carSpend higher than car room temperature, indoor air inlet, outdoor exhaust outlet is opened, and utilizes the cold air of air-conditioning in carCooling power battery, cooling effect is better, hot gas is discharged outside car simultaneously, also can fall to a certain extentThe load of low air-conditioning.
