Through slot 115 and the fluid course 125 form one for the channel of liquid flowing, liquid can by the liquid stream connector 130 and
The connectivity slot 115 flows into the fluid course 125 or the outflow fluid course 125.Optionally, multiple liquid streams connect
First 130 middle part liquid separation stream connector 130 is used as liquid outlet, and another part liquid stream connector 130 is used as inlet.
In the present embodiment, the fixed frame 110 includes 4 frameworks 112 and 4 interconnecting pieces 113.Each framework
112 are arranged between two interconnecting pieces 113, are equivalent to 4 frames and are sequentially connected end to end, to be formed described for being arranged
The accommodating space of inner sheet 120.Multiple liquid stream connectors 130 are arranged at least one described framework 112 and/or at least one institute
It states on interconnecting piece 113.It follows that the liquid stream connector 130 can be set in any position of the fixed frame 110, as long as
Guarantee can inject liquid into fluid course 125 through the liquid stream connector 130 and the connectivity slot 115.
Fig. 1, Fig. 3 are please referred to, Fig. 3 is the two of the diagrammatic cross-section of structure of controlling temperature 100 provided in an embodiment of the present invention.In reality
It applies in a kind of embodiment of example, the liquid stream connector 130 is two, and two liquid stream connectors 130 are separately positioned on and same frame
On two interconnecting pieces 113 that body 112 connects, and it is arranged in the same side (same side of the i.e. described fixed frame 110), wherein one
A liquid stream connector 130 is used as inlet, another liquid stream connector 130 is used as liquid outlet.
Referring to figure 4., Fig. 4 is the three of the diagrammatic cross-section of structure of controlling temperature 100 provided in an embodiment of the present invention.Two liquid streams
Connector 130 may be also respectively disposed on different interconnecting pieces 113, and two liquid stream connectors 130 are in 90 degree, as shown in Figure 4.
Of course, it should be understood that above are only for example, multiple liquid stream connectors 130 can be set described solid
Determine the fixation position of frame 110, the liquid stream connector 130 can be 2, or 3 (for example, two liquid streams connect in Fig. 3
One liquid stream connector 130 is set again between first 130), it can be configured according to actual needs.
In the present embodiment, the soft-package battery can also include tab, and the thickness of the interconnecting piece 113 is greater than the frame
The thickness of body 112.The difference of the thickness of the thickness and framework 112 of the interconnecting piece 113 and the thickness matching of the tab.By
This, when being assembled, the tab can be stretched out from a gap.
In the present embodiment, the thickness of the fixed frame 110 can be configured according to demand, if the fixed frame 110
Thickness it is corresponding with the thickness of two soft-package batteries, the fixed frame 110 can be used for fixing two soft-package batteries, the inner sheet
120 are embedded in the middle section of 110 thickness of fixed frame, are located at the opposite two sides of the inner sheet 120 to form two
Accommodation groove.
Referring once again to Fig. 2, the structure of controlling temperature 100 can also include separator 121.The setting of separator 121 exists
In the fluid course 125, the fluid course 125 can be divided for multiple subchannels 123, to avoid in liquid in the liquid stream
Distributed pole is uneven in channel 125, and can also play a supportive role to the inner sheet 120.The distribution of the subchannel 123 and
Size is matched with the Temperature Distribution of soft-package battery.
Optionally, the separator 121 can be one, or multiple.In the present embodiment, the separator
121 is multiple, preferably to control the distribution of liquid stream, so that the temperature control effect to soft-package battery is more preferable.Optionally,
The adjacent separator 121 is not connected to.
Since the different spot temperature of the soft-package battery is different, in order to guarantee temperature control effect, the separator 121
Between interval it is different so that the Temperature Matching of the distribution of liquid and each position of soft-package battery.For example, if the soft-package battery
Middle position temperature it is higher, then in the fluid course 125 density of the separator 121 in region corresponding with the part and its
The density of the separator 121 in remaining region is big, thereby guarantees that the heat dissipation effect in middle position.
Optionally, multiple separators 121 can use mode disposed in parallel, can also be using not parallel setting
Mode, determines according to actual conditions.The separator 121 can be strip, or other shapes, for example, bending.
When the separator 121 is strip, the length extending direction of the separator 121 can be with the fixed frame
110 length extending direction is identical, that is, as shown in Figure 3.Or, the length extending direction of the separator 121 and the fixed frame
110 width extending direction is identical.The length extending direction of the separator 121 can also be with the length of the fixed frame 110
Extending direction is in other angles.
