It rings, is not able to satisfy use in hot weather.Existing battery temperature control, high frequent are opened, and service life is influenced.Electricity
Liquid in-out temperature control in pond is unstable, inaccurate.
A kind of battery constant temperature system for applying for Patent No. CN207098015U before our company, there are temperature control is unstable
It is fixed, inaccurate, the deficiencies of influencing components service life place.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of BTS battery constant temperature system,
Product design is calorified into integrated product at refrigeration cooling, natural cooling, PTC, with can according to liquid (ethylene glycol,
Silicone oil etc.) actual temperature, in conjunction with outside air temperature, automatic switchover system operating scheme can guarantee continuing for battery operation environment
The advantage of constant temperature.Current battery optimum working temperature is 20-35 degrees Celsius (battery leaving water temperature), so the purpose of this set system
It exactly controls battery coolant liquid (dimethicone) and goes out liquid temperature within this range, to guarantee battery in optimal working environment
Interior work.
To achieve the above object, the present invention provides the following technical scheme that a kind of BTS battery constant temperature system, feature exist
In, including refrigeration system control, air cooling system control and heating system control, battery both sides are respectively as follows: battery feed liquor temperature end
Go out liquid temperature end with battery, fills battery coolant liquid in the battery；
Heating system control, it is the sequentially connected water valve COOL of battery feed liquor temperature end connecting pipeline, ptc heater, board-like
Heat exchanger, water pump to battery go out liquid temperature end；
Refrigeration system control, the sequentially connected compressor of battery feed liquor temperature end connecting pipeline, condenser, expansion valve, plate
Formula heat exchanger；
Air cooling system control, opens up on the connecting pipeline between the battery feed liquor temperature end and the water valve COOL point
Bye-pass is sequentially connected water valve FAN, radiator, blower, water pump through to battery and goes out liquid temperature end；
Further, the battery coolant liquid is with refrigerant in refrigeration system control loop inside the plate heat exchanger
Flow direction is opposite.
By using above-mentioned technical proposal, heat exchange efficiency is improved, cooling effect is increased.
It further, further include installation shell, the installation shell includes four mutually isolated chambers, and institute is respectively set
State condenser, plate heat exchanger, compressor, ptc heater.
By using above-mentioned technical proposal, space has been saved in integrated form installation, shortens connecting pipeline.
In conclusion the invention has the following advantages: raising heat exchange efficiency, increases cooling effect.Solves electricity
The unusual fluctuations of pond running temperature, so that battery temperature control stablizes, is accurate.Guarantee that battery is run under isoperibol, improves
The service life of battery, battery temperature control open compressor need not frequently, prolong the service life.Improve heat exchange effect
Rate enhances cooling effect.
