It will be appreciated that though various information, but this may be described using term first, second, third, etc. in the application
A little information should not necessarily be limited by these terms.These terms are only used to for same type of information being distinguished from each other out.For example, not departing from
In the case where the application range, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as
One information.Depending on context, word as used in this " if " can be construed to " ... when " or " when ...
When " or " in response to determination ".
The present invention will be described in further detail below with reference to the embodiments of the drawings.
Referring to Fig. 2 and Fig. 3, Vehicular battery device of the present invention is applied to automotive field, is particularly suitable for electric car or mixed
Close power vehicle.The coolant 30 of the Vehicular battery device selects air, or through filtered in a preferred embodiment
Air.In other embodiments, the gas that other stability are good or impurity is less, such as nitrogen also can be selected.
With continued reference to Fig. 2, the Vehicular battery device include shell 10, be set in shell several battery units 12 and with
The electrical component that battery unit 12 connects.The shell 10 is internally divided at least two cavitys, including accommodates battery unit 12
Battery container chamber 11 and the setting electrical component electrical accommodating chamber 20.The electrical component is mainly used for boosting battery work
Make comprising battery management system 16, power relay component 15, manual maintenance decoupler 14, connector 13 and (not shown)
The elements such as sensor, cable.The battery unit 12 and electrical component are configured to contact discharge heat by the coolant with flowing
Amount.It is connected between the battery unit 12 by series system or parallel way, so that obtaining has certain power and voltage
Power supply, and be electrically connected by the way that the dynamical system of connector 13 and automobile is (not shown), to realize power output.
The battery container chamber 11 is defeated equipped with the first input port 17 and outflow coolant 30 first flowed into for coolant 30
Outlet 18.The electrical accommodating chamber 20 second equipped with the second input port 21 and outflow coolant 30 that flow into for coolant 30 is defeated
Outlet 22.Coolant 30 separately flows into battery container chamber 11 and electrical receiving by the first input port 17 and the second input port 21
Chamber 20, and it is electrical first with battery unit 12 and battery management system 16, power relay component 15, manual maintenance decoupler 14 etc.
Part comes into full contact with concurrent heat exchange (i.e. absorption battery unit and the heat of electrical component generation), absorbs the coolant of heat
It is flowed out again via the first delivery outlet 18 and the second delivery outlet 22.Significantly, since impurity is more in air, it is exposed to electricity
Electrical component is easier to break down under the action of impurity in gas accommodating chamber, and (single battery unit, i.e. battery core, appearance originally have
Protective layer, not vulnerable to impurity effect), therefore be less than by the flow of the coolant of electrical accommodating chamber 20 and pass through battery container chamber 11
Coolant flow, and for the heat generated compared to battery unit, the heat that electrical component generates is also less, so few
Fully absorbing to the heat of electrical component still may be implemented in the coolant of amount.Therefore, " the first input port 17 --- battery is received
Cavity 11 --- the first delivery outlet 18 " can be considered main line cooling system, " the second input port 21 --- electrical accommodating chamber 20 --- the
Two delivery outlets 22 " can regard branch line cooling system as.
Cell managing device 16, power relay component 15, manual maintenance decoupler 14 electrical accommodating chamber 20 lengthwise
Direction and short transverse are in the arrangement that offsets one from another, and with the contact area of further expansion and coolant 30, improve cooling effect.
In another embodiment, the surface for the electrical accommodating chamber 20 that coolant 30 flows through is additionally provided with fin, effectively increase electrical component with
The contact area of coolant 30, allows coolant largely to absorb heat.Shown in referring to figure 3., the fin 4 is implemented one
It is arranged in example in the radial mode of diagram.Wherein, several cooling fins 41 are equipped with, on the fin 4 to connect with coolant 30
Touching, and realize good heat dissipation performance.Certainly in other embodiments, fin can also be in shape arrangement or the helical form row of being in alignment with each other
Column, to obtain sufficiently large heat-conducting area.
In addition, in the present embodiment, the second input port 21 and the first of battery container chamber 11 of the electrical accommodating chamber 20
Input port 17 is connected to, and the second delivery outlet 22 of the electrical accommodating chamber 20 is connected to the first delivery outlet 18 of battery container chamber, this
Sample need to only open up an entrance and one outlet on shell 10 can form the circulation path of coolant 30.And in order to control two
The coolant flow of person, the size of the second input port 21 is the size 45% to 55% of the first input port 17, cold under this ratio
But effect is good and electrical component is also not easy to accelerate aging because of overheat.Certainly, the first input port 17 and the second input port 21 are also set
It is equipped with valve (not shown), preferably by electronically controlled solenoid valve, solenoid valve can carry out real-time control to coolant flow.
The direction that the coolant 30 flows into the first input port 17 is identical as the outflow direction of the first delivery outlet 18, coolant
30 flow into the direction of the second input ports 21 and the second delivery outlet 22 of outflow on the contrary, and first input port 17 and the second input port
21 vertical connections, 22 vertical connection of first delivery outlet 18 and the second delivery outlet, this is mainly by Vehicular battery device of the present invention
Structure determine, can be changed as desired in other embodiments.
Upward in coolant flow classical prescription, the downstream of the first input port 17 is arranged in second input port 21.
The present invention cools down battery unit and electrical component by the way that the coolant in different channels is arranged respectively, and fin
Design and the arrangement of electrical component then advanced optimized the cooling effect to electrical component, to solve Vehicular battery dress
The problem of thermal stress for the electrical component set is larger and overaging, while according to the control of coolant flow, it can avoid battery
Internal electrical component influences the working performance of battery due to by polluting.
Although having illustrated and having described only certain features and embodiment of the invention, those skilled in the art are not
Many modifications and change can be carried out in the case where the novel teachings and advantage that are substantially detached from the theme illustrated by claims
Change (for example, the variation of the size of various elements, size, structure, shape and ratio, parameter value (for example, temperature, pressure etc.), peace
Fill the variation of arrangement, the use of material, color, orientation etc.).Any process or the order or sequence of method and step can be according to can
Alternate embodiment and change or resequence.It is therefore understood that the appended claims be intended to cover to fall into it is of the invention true
All such modifications and variations in the range of positive spirit.
In addition, not describing all features of actual implementation mode to provide the brief description of exemplary embodiment
(that is, with the incoherent feature of preferred forms of the invention that proposes at present, or with realize claimed invention not phase
The feature of pass).It, can as in any engineering or design object it should be appreciated that in developing any this actual implementation mode
To make many decisions embodied according to embodiment.This development effort may be complex and time-consuming, but for from originally
For the benefited those of ordinary skill of invention, this may be only the normal work to do of design, preparation and manufacture, without excessive
Experiment.
