Referring to fig. 1, fig. 1 is a schematic diagram of an even distribution type thermal management system applied to a battery module 20, where the even distribution type thermal management system includes a plurality of thermal management devices 100, and each thermal management device 100 works independently to control the temperature of two adjacent battery modules 20. The thermal management device 100 includes a heat transfer assembly 110, a control assembly 120, and a heat generation assembly 130.
The heat transfer assembly 110 is disposed between adjacent two of the battery modules 20, and transfers heat.
The heat generating assembly 130 is attached to the heat transfer assembly 110.
The control assembly 120 is connected to the heat transfer assembly 110 and the heat generating assembly 130, and the control assembly 120 controls the heat generating assembly 130 to heat the heat transfer assembly 110.
In this way, the centralized temperature control by the distributed thermal management system instead of the prior art can more specifically control the temperature of the battery modules 20 at different temperatures.
Specifically, referring to fig. 2, in the present embodiment, the heat generating assembly 130 includes a heating film 131 and heating wires 132 that are roundabout disposed in the heating film 131, and two ends of the heating wires 132 are respectively connected to the control assembly 120. The control assembly 120 outputs current to the heating wire 132, and the heating wire 132 generates heat after being electrified, and the heat is transferred to the battery module 20 through the heat transfer assembly 110.
Specifically, in the present embodiment, the heat transfer assembly 110 performs temperature transfer by a thermally conductive liquid flowing therein. The heat transfer component 110 comprises a hollow heat conducting plate and a liquid channel which is arranged in the hollow heat conducting plate in a roundabout way, wherein a liquid inlet and a liquid outlet of the liquid channel are respectively connected with the control component 120, and the control component 120 enables heat conducting liquid to circularly flow in the heat transfer component 110.
When the temperature of the battery module 20 is too low, the heat transfer assembly 110 transfers the heat generated by the heat generation assembly 130 to the battery module 20 through the heat conductive liquid under the control of the control assembly 120, so as to achieve the effect of heating the battery module 20. In this embodiment, the heat conductive liquid may be water.
Referring to fig. 3, in one implementation of the present embodiment, the liquid channel 112 may be a liquid conduit that is disposed around the hollow heat conducting plate 111. The hollow heat-conducting plate 111 is attached to the adjacent two battery modules 20 to transfer heat to the battery modules 20.
Referring to fig. 4, in another implementation of this embodiment, the liquid channel 112 may be formed by dividing a plurality of liquid partitions in the hollow heat conducting plate 111. The hollow heat-conducting plate 111 is attached to the adjacent two battery modules 20 to transfer heat to the battery modules 20.
The liquid channel 112 includes a liquid inlet 1121 and a liquid outlet 1122, and the liquid inlet 1121 and the liquid outlet 1122 are respectively connected to the control assembly 120. The heat-conducting liquid enters the liquid channel 112 from the liquid inlet 1121 under the driving of the control component 120, and flows back to the control component 120 from the liquid outlet 1122 after detouring in the liquid channel 112.
It should be noted that, in the present embodiment, the liquid channels 112 shown in fig. 3 or fig. 4 are only schematic illustrations of the arrangement of the liquid channels 112 provided in the present embodiment, and the number and the roundabout manner of the liquid channels 112 are not limited to those shown in fig. 3 or fig. 4, and a plurality of liquid channels 112 and different roundabout manners may be provided. When a plurality of liquid channels 112 are provided, the liquid inlets 1121 and the liquid outlets 1122 of the liquid channels 112 may be disposed at different positions, so that the heat-conducting liquid flows in different liquid channels 112 are different, and the effect of further equalizing the temperature is achieved.
Based on the above design, compared with the prior art in which the heat-conducting liquid is heated at one end of the heat transfer assembly, the heat generating assembly 130 provided in this embodiment can heat the heat transfer assembly 110 more uniformly, so that the heat transfer assembly 110 can transfer heat to the battery module 20 more uniformly.
Further, referring to fig. 5, in the present embodiment, the heating wires 132 are arranged in a plurality of parallel rows in the heating film 131 in a detour manner. The extending direction of the liquid channel 112 in the heat transfer module 110 is perpendicular to the extending direction of the heating wire 132 in the heat generating module 130. In this way, the heat-conductive liquid in the liquid channel 112 can be heated more uniformly by the heating wire 132.
Further, each of the thermal management devices 100 may include two heat generating assemblies 130, and the two heat generating assemblies 130 are respectively attached to opposite sides of the heat transfer assembly 110.
Further, the thermal management device 100 also includes a temperature acquisition assembly 140.
The temperature collection assembly 140 is disposed on the battery module 20, and the temperature collection assembly 140 collects the temperature of the battery module 20 and sends the temperature to the control assembly 120, so that the control assembly 120 controls the heat transfer assembly 110 to raise or lower the temperature according to the temperature of the battery module 20. In this embodiment, the temperature acquisition component 140 may include, but is not limited to, a thermocouple, a thermal resistor, or the like.
Further, referring to fig. 6, since one thermal management device 100 acts on two adjacent battery modules 20, in this embodiment, the thermal management device 100 between two adjacent battery modules 20 includes at least two temperature acquisition assemblies 140.
The two temperature collection assemblies 140 are respectively disposed on the two adjacent battery modules 20, and are configured to collect temperatures of the two adjacent battery modules 20 and send the temperatures to the control assembly 120, so that the control assembly 120 controls the heat transfer assembly 110 to raise or lower the temperature according to the obtained average temperature value of the two battery modules 20.
Referring to fig. 6 again, in the present embodiment, the thermal management device 100 located at one side of the single battery module 20 includes at least one temperature acquisition component 140, and only the temperature of one battery module 20 is acquired as the basis of temperature control.
In this way, the temperature of each battery module 20 is collected by the plurality of thermal management devices 100 as a basis for temperature control, so that the temperature of the battery modules 20 with different temperatures can be controlled more accurately.
In this embodiment, the control unit 120 controls the heat generation unit 130 to generate heat to heat the battery module 20 according to the temperature information collected by the temperature collection unit 140.
Specifically, when the control module 120 receives that the battery temperature acquired by the temperature acquisition module 140 is lower than a temperature threshold, a temperature raising process is performed on the battery module 20.
Further, referring to fig. 7, in the present embodiment, the distributed thermal management system further includes a centralized monitoring device 200.
The centralized monitoring device 200 is connected to each of the thermal management devices 100, and the centralized monitoring device 200 obtains the temperatures of the battery modules 20 obtained by the plurality of temperature collection assemblies 140, and issues a temperature adjustment signal to the control assembly 120 according to the temperatures of the battery modules 20.

In this way, by adopting the uniformly distributed thermal management system, the plurality of thermal management devices 100 work relatively independently, and each control component 120 corresponds to one heat transfer component 110, so that the defect that a single heat source or cold source cannot perform uniform temperature control on each battery module 20 under the condition of excessive battery modules 20 is overcome.
Further, in this embodiment, the centralized monitoring device 200 is further configured to connect to a display device, and send the temperature information of each battery module 20 to the display device for displaying.
In this way, the user can intuitively grasp the temperature condition of each of the battery modules 20.
Further, in the present embodiment, the heat generating assembly 130 may further include a semiconductor heating unit. The semiconductor heating unit is connected with a connection control assembly 120, which controls the heating temperature of the semiconductor heating unit through the intensity of the output current.
The present embodiment also provides a battery, which includes a plurality of battery modules 20 and the uniform thermal management system provided in the present embodiment.
In summary, according to the uniformly distributed thermal management system and the battery provided by the invention, the plurality of thermal management devices 100 are provided, and each thermal management device 100 includes a heat transfer assembly 110 disposed between two adjacent battery modules 20, and a control assembly 120 connected to the heat transfer assembly 110.
