Description
Technical field
The present invention relates to the PACK heat management device of a kind of more options, particularly relate to a kind of batteries of electric automobile group PACK heat management device.
Background technology
Along with the development of electric vehicle engineering, the related invention creation for electric automobile power battery group cooling system also day by day increases.Research and development about electric automobile power battery group cooling system are with set of cells uniform heat distribution for main goal in research at present, all without considering electric automobile energy saving and effectively utilizing.The storage capacity of present battery is limited, in order to obtain longer course continuation mileage, it is necessary at many-sided saving energy.Existing electric automobile power battery group cooling system is when summer condition, and the hot-air discharged from electric automobile power battery group cooling system is discharged into external environment condition.It is true that under electric automobile normal operating condition, the heat dissipation capacity of battery is only small, after air-conditioner wind cooling battery, its hot air temperature is still below vehicle exterior ambient air temperature.During winter condition, from pile cooling, expellant gas temperature is higher than vehicle exterior ambient temperature, therefore the type of cooling poor effect of current electric automobile lithium battery group on the market.
And electric automobile is many using lithium battery as drive energy in the market, although lithium battery can meet this requirement in many-side, but lithium battery is higher to the requirement using temperature in groups, and then the heat management of lithium electricity is also the important component part of excellent battery group.I takes charge of through test of many times, now have devised efficient, the battery of more options heat management system in groups.
Summary of the invention
It is an object of the invention to provide the PACK heat management device of a kind of more options, including battery management system, DC speed regulation fan 2, some set of cells 4, casing, wind inlet channel 3, return air channel 5, heat exchange module 1；Described heat exchange module is processed by aluminium sheet and is welded welded seal, burst pressure 80KG with laser or agitating friction after interior media runner, selects heat transferring medium according to service condition, such as motor vehicle antifreeze fluid, such as R134a coolant；Affiliated casing is the double-decker of protection set of cells, has air channel between every batteries, and described some set of cells are parallel way, and separate；Described battery management system gathers the temperature of each set of cells, and fan is carried out speed governing；
Described heat exchange module is disposable, it can use with water for heat transferring medium, also can be that heat transferring medium uses as the coolant of compression refrigeration, be alternatively arranged as with coolant or water be heat transferring medium heat exchange of heat pipe use, occupation mode coordinates the circulation air path of casing flexibly, plus outstanding battery management system, solve a set of cells requirement difficult problem to temperature stabilization, constitute reliable electric automobile PACK managing device.
Heat exchanger is under the forced ventilation of fan, air after supercooling or heating is blown into wind inlet channel, the cavity of several set of cells is entered after distribution of air flow, after the battery being had heat exchange to need is carried out heat balance displacement, being blown into return air channel, the air after variations in temperature is again introduced into heat exchange module and carries out heat exchange, then subsequent cycle is carried out, some set of cells cavity lane are parallel way, and separate, it is to avoid interference in air flow causes heat non-uniform phenomenon.Fan can be carried out speed governing according to each module temperature that battery management system (BMS) gathers by DC speed regulation fan, increases or reduces air circulation, carrying out the intelligent management of temperature.Due to the application of casing circulation air path, and the Parallel Design in battery modules air channel so that it is heat exchange efficiency exceeds 3 times than other heat exchange forms, and the temperature difference of cell is less than 0.8 degree Celsius.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention
Detailed description of the invention
Below in conjunction with accompanying drawing 1 and specific embodiment, the invention will be further described.
Described air channel is the air channel, both sides that route is battery case body of arrow 3 indication, and this air channel make use of the casing double-decker to battery protection cleverly, and 4 regions are the battery assembling and putting casing into; air channel is had between every batteries; 5 arrow region return air channels, 1 heat exchange module
Heat exchanger is under the forced ventilation of fan, air after supercooling or heating is blown into wind inlet channel, the cavity of several set of cells is entered after distribution of air flow, after the battery being had heat exchange to need is carried out heat balance displacement, being blown into return air channel, the air after variations in temperature is again introduced into heat exchange module and carries out heat exchange, then subsequent cycle is carried out, some set of cells cavity lane are parallel way, and separate, it is to avoid interference in air flow causes heat non-uniform phenomenon.Fan can be carried out speed governing according to each module temperature that battery management system (BMS) gathers by DC speed regulation fan, increases or reduces air circulation, carrying out the intelligent management of temperature.Due to the application of casing circulation air path, and the Parallel Design in battery modules air channel so that it is heat exchange efficiency exceeds 3 times than other heat exchange forms, and the temperature difference of cell is less than 0.8 degree Celsius.
Disposable heat exchange module, it can use with water for heat transferring medium, also can be that heat transferring medium uses as the coolant of compression refrigeration, state and can use as the heat exchange of heat pipe being heat transferring medium with coolant or water, occupation mode coordinates the circulation air path of casing flexibly, plus outstanding battery management system, solve a set of cells requirement difficult problem to temperature stabilization, constitute reliable electric automobile PACK managing device.
Above-described embodiment is used for illustrative purposes only, and is not limitation of the present invention, about the those of ordinary skill of technical field, without departing from the present invention, can also making a variety of changes and modification, therefore, all equivalent technical schemes also should belong to scope of the invention.
