That measures distributes the service life that can affect battery not in time.In order to improve the performance of set of cells, need to be to battery when temperature is too high
Group is effectively cooled down, and enables set of cells normal work.Normal battery does not adopt heat management or adopts air-cooled management, electricity
Group intensive local heat in pond is not easy to distribute in time, thereby results in that battery efficiency is low, reduces the service life of battery,
The safety that impact uses.And battery temperature skewness causes battery capacity decay inconsistent, the contracting of set of cells comprehensive life
Short, affect service life and the course continuation mileage of electric automobile.
Utility model content
For solve batteries of electric automobile group service life is short now, efficiency for charge-discharge is low, battery capacity decay inconsistent and
The bad problem of safety, this utility model provides a kind of use conduction oil to carry out the set of cells of heat management.
This utility model is realized by following technical proposals.
A kind of use conduction oil carries out the set of cells of heat management, it is characterized in that, including oil guide pipe, cuboid battery case body
With some transversely adjacent battery units being arranged in battery pack box body；Battery unit includes cuboid-type battery and is fixed on electricity
The rectangle fixed plate on pond top, the length of fixed plate is equal to the length of battery upper surface, and width is more than the width of battery upper surface
Degree；It is evenly equipped with some semicircle fixed plate through holes, battery bottom sets the battery through hole extending transversely through at fixed plate both sides of the edge；Lead
Oil pipe top be in handle-type, end cell group body side top connect, the other end with battery case body another side bottom
Connection, is filled with conduction oil in the space in battery case body and oil guide pipe.
The described set of cells carrying out heat management using conduction oil, wherein, battery through hole is located in the middle of battery bottom, for half
Circular.
Preferably, conduction oil burning-point is more than 300 DEG C, and dielectric strength is more than 30kV, and viscosity is less than 20cst, condensation point is less than -10
℃.
Preferably, oil guide pipe material is corronil.
The beneficial effects of the utility model are as follows.
1st, thermal diffusivity is good, by the conduction of heat of conduction oil, the high rising of temperature, and the low decline of temperature, form radiating circulation,
Radiated by the naked corronil oil guide pipe being exposed on the external.
2nd, improve battery Comprehensive service life, each battery temperature is balanced by conduction oil, so that temperature difference is controlled at 1.5 degree
Interior, so that battery capacity is decayed consistent, battery in the circulating cycle concordance high it is ensured that electric automobile course continuation mileage and service life.
3rd, install conveniently moving, handle-type oil guide pipe arrange, not only can heat conducting and radiating, can also work as handle use,
So that set of cells is lifted, put down convenient.

Specific embodiment
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further.
A kind of use conduction oil carries out the set of cells of heat management, is in corronil oil guide pipe 6, the length of handle-type including top
Cube shape battery case body 1 and 3 transversely adjacent battery units being arranged in battery case body 1；Battery unit is by cuboid
Battery 2 forms with the rectangle fixed plate 3 being fixed on battery 2 top, and the length of fixed plate 3 is equal to the length of battery 2 upper surface,
Width is more than the width of battery 2 upper surface；At the both sides of the edge of fixed plate 3 length, relevant position is evenly equipped with 5 semicircles respectively
Fixed plate through hole 5, sets the semicircle battery through hole 4 that Open Side Down, extends transversely through battery 2 in the middle of battery 2 bottom；Oil guide pipe 6
One end is connected with the top of battery case body 1 side, and the other end is connected with the bottom of battery case body 1 another side, set of cells
It is filled with confined space in casing 1 and oil guide pipe 6 that burning-point is more than 300 DEG C, dielectric strength is more than 30kV, viscosity and is less than
The conduction oil that 20cst, condensation point are less than -10 DEG C.
When set of cells is using a period of time or discharge and recharge, battery 2 is internal to be produced more heat and is delivered to its surface,
There is certain temperature difference in battery 2 surface temperature and conduction oil, due to the effect of convection current and radiation, heat will pass to neighbouring
Conduction oil, so that conduction oil oil temperature is gradually increasing.After heat conduction oil temperature near battery 2 raises, high-temperature heat-conductive oil flow rate
Increase, thus extruding flows up, be upward through fixed plate through hole 5 and flow to oil guide pipe 6 and connect with battery case body 1 side top
One end, by the outside radiating of exposed corronil oil guide pipe 6, after transmitting heat, conduction oil oil temperature reduces, temperature
Low conduction oil flows downward along oil guide pipe 6 opposite side, flows into battery case body 1 by the opposite side bottom of battery case body 1
Inside, passes through battery through hole 4, the vacancy of the low conduction oil filled high-temperature conduction oil of temperature, thus looping back forming radiating
Road.Persistently set of cells is cooled down in real time, and be can guarantee that the battery temperature difference controls in 1.5 DEG C, so that battery capacity is decayed consistent,
Battery in the circulating cycle concordance high it is ensured that electric automobile course continuation mileage and service life.
Conduction oil burning-point be more than 300 DEG C, dielectric strength be more than 30kV, viscosity be less than 20cst, condensation point be less than -10 DEG C, be for
Ensure that conduction oil is nonflammable, be not susceptible to electrical short, spark and ensure the good heat-transfer character of conduction oil.
