Description
Technical field
It the utility model is related to battery case field, and in particular to a kind of battery case of double refrigeration.
Background technology
For tramcar mostly using superbattery as stored energy mechanism, superbattery is to be divided into hundreds of pieces of single batteries
Several battery units, form high pressure, the battery pack of high current, the several piece single battery of each battery unit after series and parallel
It is placed in a babinet, partition plate is placed between adjacent single battery；The temperature range for making battery be maintained at 24 ~ 30 degrees Celsius
Interior work, can effectively improve the charge and discharge efficiency of battery, extend the service life of battery, it is therefore necessary to be dissipated using suitable
Hot measure come tackle battery work caused by amount of heat.
Have at present and battery is mounted in internal box made of Heat Conduction Material, internal box is put into outer case, in the inner box
Circulation is passed through conduction oil, and the cold air that the refrigeration mechanism being battery powered produces is blown into take away heat by outer case by pipeline
Scheme, due to battery charging caused by heat will be far more than heat caused by electric discharge, this requires when battery charges
It is blown into more cold airs, the prior art is realized increasing in refrigeration mechanism by way of compressor horsepower, and compressor is same
When also consume more electricity, this just extends the charging interval of battery.
The content of the invention
The technical problem to be solved by the present invention is to provide a kind of battery case of double refrigeration, the prior art can be solved and led to
Cross and increase the mode of compressor horsepower in refrigeration mechanism and realize fast-refrigerating when charging to battery, cause to extend battery
The problem of charging interval.
The utility model is achieved through the following technical solutions：
A kind of battery case of double refrigeration, including internal box made of outer case, Heat Conduction Material, the internal box are placed on outer container
In body, battery is placed with the internal box, is placed with partition plate between adjacent battery, the internal box inner cavity through oil inlet pipe,
Oil return pipe connects oil storage tank, and the oil inlet pipe is equipped with oil pump, and the outer case bottom is provided with heat emission hole, and intracavity bottom is set
Have an outer radiating groove, the outer radiating groove connects refrigeration mechanism by pipeline, is parallel with branch on the pipeline, on the branch according to
Secondary to be equipped with wind turbine, energy storage canister and shut-off valve, the controller of the shut-off valve is connected to the charging circuit of battery.
The further scheme of the utility model is that pressure switch is provided with the energy storage canister, the pressure switch it is defeated
Outlet connects the power cord of wind turbine, and when the pressure that pressure switch is detected in energy storage canister is higher than default threshold value, wind turbine stops.
The further scheme of the utility model is that the internal box intracavity bottom is provided with interior radiating groove, the oil inlet pipe
Radiating groove in connection.
The further scheme of the utility model be provided with the partition plate it is convex stupefied.
The utility model compared with prior art the advantages of be：
First, during battery discharge, a part of cold air that refrigeration mechanism produces is stored in energy storage canister, is blown into together when battery charges
Babinet realizes fast-refrigerating, and refrigeration mechanism will not extend the charging interval of battery with stable Power operation；
2nd, pressure switch prevents that hypertonia forms security risk in energy storage canister, and can prevent wind turbine overload damage；
3rd, interior radiating groove makes somebody a mere figurehead battery bottom, has the contact surface of bigger between conduction oil, quickly takes away heat,
And make the heat distribution of battery more uniform；
4th, it is convex it is stupefied make to form runner between battery, accelerate the cooling of battery, prevent heat from gathering.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
