Description

Technical Field

[0001] The present invention relates to a temperature regulating plate and a temperature regulating device, and in particular to a temperature regulating plate and a temperature regulating device for a battery. Background Art

[0002] Currently, the mainstream temperature regulating plates adopt a single-in and single-out mode. If the modules or the battery in the battery are relatively large, there may be a large temperature difference in the batteries near the inlet and outlet positions due to the increase in the temperature of the fluid.

[0003] In addition, if the installed module is relatively long, due to the stronger heat dissipation of the end plates at both ends of the module, the temperature of the batteries in the middle of the module is higher, and the temperatures of the batteries at both ends are lower. Moreover, after the fluid enters the temperature regulating plate from a single inlet, as the flow path grows, the temperature regulating ability of the fluid will also decrease.

[0004] In terms of thermal management control, if a single-in and single-out mode temperature regulating plate is adopted, when adjusting the temperature difference and high temperature in the battery, only the overall regulation of the batteries in the package can be achieved, that is, regulating the flow rate and temperature of the inlet fluid. It may occur that in order to control the highest temperature, the temperature difference between the batteries cannot be effectively controlled. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defect of large temperature difference in the battery in the prior art, and provide a temperature regulating plate and a temperature regulating device.

[0006] The present invention solves the above technical problem through the following technical solutions:

[0007] A temperature regulating plate, which is used for circulating a temperature regulating fluid to regulate the temperature of a battery. The temperature regulating plate includes a body part, an inlet and an outlet. The body part is used for connecting with the battery.

[0008] The body part has a main channel and at least one secondary channel. Both ends of the main channel are communicated with the inlet and the outlet respectively. One end of the secondary channel is communicated with the inlet, and the other end of the secondary channel is communicated with the main channel. The temperature regulating fluid flows in from the inlet, passes through the main channel and the secondary channel, and then flows out of the body part from the outlet.

[0009] In this solution, after the temperature-regulating fluid enters from the inlet, part of the fluid enters one end of the main channel, and part of the fluid enters one end of the secondary channel. The other end of the secondary channel is connected to the main channel. The part of the fluid that enters the secondary channel flows into the main channel from the other end of the secondary channel and mixes with the fluid in the main channel. Thus, through the temperature-regulating plate in this solution, the temperature-regulating fluid can be distributed, so that part of the fluid can regulate the temperature of the battery as a whole through the main channel, and part of the fluid mixes with the fluid in the main channel at each secondary channel, so that the corresponding downstream area of the battery can be regulated by the part of the fluid in the secondary channel, thereby being able to balance the temperatures of all areas of the battery and reduce the temperature difference of the battery.

[0010] Especially for a battery with a long module or an extra-long module, the temperature-regulating plate can locally regulate the temperature of the middle area of the battery, which can not only improve the temperature-regulating efficiency, but also make the temperature regulation more accurate, reduce the temperature difference between the batteries, and improve the temperature consistency of the module.

[0011] Preferably, along the flow direction of the temperature-regulating fluid, the communication ports of the plurality of secondary channels and the main channel are spaced apart from each other.

[0012] In this solution, the communication ports of the multiple secondary channels and the main channel are spaced apart, so that the secondary channels act on different areas of the battery, balance the temperature difference in each area of the battery, and improve the temperature-regulating effect.

[0013] Preferably, the diameter of the main channel is larger than the diameter of the secondary channel;

[0014] And / or, the diameter of the secondary channel is related to the temperature of the corresponding battery area downstream.

[0015] In this solution, the diameter of the main channel is larger than that of the secondary channel, so that most of the temperature-regulating fluid enters the main channel to mainly dissipate heat from the battery; a small part of the temperature-regulating fluid enters each secondary channel and mixes with the fluid in the main channel to reduce the temperature of the fluid in the main channel, thereby enhancing the temperature-regulating ability of the fluid in the main channel for the battery area located downstream of the secondary channel. In addition, the diameter of the secondary channel can also be adaptively designed according to the requirements of the battery area located downstream of it, so as to improve the accuracy of temperature regulation.

[0016] Preferably, the included angle between the opening direction of the communication port of the secondary channel and the main channel and the flow direction of the temperature-regulating fluid in the main channel is an acute angle.

[0017] In this solution, the included angle between the opening direction of the secondary channel and the flow direction of the temperature-regulating fluid is an acute angle. On the one hand, part of the fluid can flow along the flow direction of the fluid after entering the secondary channel; on the other hand, part of the fluid entering from the secondary channel can also disturb the flow field of part of the fluid in the main channel, enhance the heat transfer between the temperature-regulating fluid and the temperature-regulating plate, and improve the temperature-regulating performance.

[0018] Preferably, the body part includes a plate body and at least one secondary pipe. The plate body is used to connect with the battery; the main channel is arranged in the plate body, and each secondary pipe is provided with one secondary channel. One end of the secondary pipe is communicated with the inlet, and the other end of the secondary pipe is communicated with the plate body.

[0019] In this solution, the main channel and the secondary channel are respectively formed by the plate body and the secondary pipe, and its structure is convenient for manufacturing and can be flexibly designed.

[0020] Preferably, the body part is in a plate-like structure, including a first side wall and a second side wall arranged oppositely. The first side wall is used to connect with the battery; in the direction from the first side wall to the second side wall, the main channel and at least one secondary channel are arranged layer by layer; the main channel is arranged close to the first side wall.

[0021] In this solution, the plate-like body part can be adapted to the outer surface of the battery. The main channel and the secondary channel are arranged layer by layer, and its structure is compact; the temperature-regulating fluid can enter from the inlet and flow towards the outlet direction in different layers after being distributed by the main channel and the secondary channel. Among them, the main channel is closer to the battery and can play a main temperature-regulating role for the battery. Multiple secondary channels can be communicated with the main channel in different layers to play an auxiliary temperature-regulating role.

[0022] Preferably, the main channel and the secondary channel are parallel to each other;

[0023] And / or, compared with the communication port of the secondary channel close to the main channel and the main channel, the communication port of the secondary channel far from the main channel is closer to the outlet.

[0024] In this solution, the farther the secondary channel is from the main channel, the closer its communication port with the main channel is to the outlet, so that part of the fluid in this secondary channel can be less affected by the temperature of the battery. After it flows to the corresponding communication port and mixes with part of the fluid in the main channel, it can still regulate the temperature of the fluid in the main channel.

[0025] Preferably, the temperature-regulating plate further includes at least one partition part. The partition part is arranged between the first side wall and the second side wall, and the partition part is arranged parallel to the first side wall and the second side wall; the communication port of the secondary channel and the main channel is arranged on the partition part.

[0026] In this solution, by providing a partition portion disposed between the first side wall and the second side wall, corresponding main channels and sub-channels can be configured to distribute and mix the temperature-regulating fluid.

[0027] Preferably, the partition portion includes a partition plate and a clamping plate. The partition plate and the clamping plate are mutually attached. The partition plate is used for heat insulation and supporting the clamping plate; the sub-channel extends from one end of the clamping plate to a position corresponding to the communication port.

[0028] A temperature-regulating device, the temperature-regulating device includes the temperature-regulating plate as described above, and there is at least one such temperature-regulating plate; the battery has a plurality of battery modules, and the temperature-regulating plate corresponds to at least one of the battery modules.

[0029] In this solution, after the temperature-regulating fluid enters from the inlet, part of the fluid enters one end of the main channel, and part of the fluid enters one end of the sub-channel. The other end of the sub-channel is communicated with the main channel, and the part of the fluid entering the sub-channel flows into the main channel from the other end of the sub-channel and mixes with the fluid in the main channel; thus, through the temperature-regulating plate in this solution, the temperature-regulating fluid can be distributed, so that part of the fluid passes through the main channel to perform overall temperature regulation on the battery, and part of the fluid mixes with the fluid in the main channel at each sub-channel, so that the corresponding area downstream of the battery can be temperature-regulated under the action of part of the fluid in the sub-channel, thereby being able to balance the temperatures of each area of the battery and reduce the temperature difference of the battery.

[0030] Especially for a battery with a long module or an extra-long module, the temperature-regulating plate can perform local temperature regulation on the middle area of the battery, which can not only improve the temperature-regulating efficiency, but also make the temperature regulation more accurate, reduce the temperature difference between the batteries, and improve the temperature consistency of the modules.

[0031] Preferably, the plurality of battery modules are arranged in sequence, and the plurality of temperature-regulating plates are arranged in sequence along the length direction of the battery, and the main channels of two adjacent temperature-regulating plates are communicated with each other;

[0032] Or, the plurality of battery modules are arranged side by side in sequence, and the temperature-regulating plates are arranged side by side in sequence along the width direction of the battery, and the main channels of two adjacent temperature-regulating plates are communicated with each other.

[0033] The positive and progressive effects of the present invention are as follows: After the temperature-regulating fluid enters from the inlet, part of the fluid enters one end of the main channel, and part of the fluid enters one end of the secondary channel. The other end of the secondary channel is connected to the main channel. The part of the fluid that enters the secondary channel flows into the main channel from the other end of the secondary channel and mixes with the fluid in the main channel. Thus, through the temperature-regulating plate in this solution, the temperature-regulating fluid can be distributed, so that part of the fluid can conduct overall temperature regulation on the battery through the main channel, and part of the fluid mixes with the fluid in the main channel at each secondary channel, so that the corresponding downstream area of the battery can be temperature-regulated under the action of part of the fluid in the secondary channel, thereby being able to balance the temperatures of each area of the battery and reduce the temperature difference of the battery.

[0056] Battery 2 Specific implementation mode

[0057] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the described embodiments accordingly.

[0058] An embodiment of the present invention provides a temperature regulating plate 1, as Figures 1-7 shown. The temperature regulating plate 1 is used for circulating a temperature regulating fluid to regulate the temperature of the battery 2. The temperature regulating plate 1 includes a body part 10, an inlet 20 and an outlet 30. The body part 10 is used for connecting with the battery 2.

[0059] There is a main channel 100 and at least one secondary channel 200 in the body part 10. Two ends of the main channel 100 are respectively communicated with the inlet 20 and the outlet 30. One end of the secondary channel 200 is communicated with the inlet 20, and the other end of the secondary channel 200 is communicated with the main channel 100. The temperature regulating fluid flows in from the inlet 20, and after passing through the main channel 100 and the secondary channel 200, it flows out of the body part 10 from the outlet 30.

[0060] After the temperature regulating fluid enters from the inlet 20, part of the fluid enters one end of the main channel 100, and part of the fluid enters one end of the secondary channel 200. The other end of the secondary channel 200 is communicated with the main channel 100. The part of the fluid entering the secondary channel 200 flows into the main channel 100 from the other end of the secondary channel 200 and is mixed with the fluid in the main channel 100. Thus, through the temperature regulating plate 1 in this solution, the temperature regulating fluid can be distributed, so that part of the fluid passes through the main channel 100 to perform overall temperature regulation on the battery 2, and part of the fluid is mixed with the fluid in the main channel 100 at each secondary channel 200, so that the corresponding area downstream of the battery 2 can be temperature-regulated under the action of part of the fluid in the secondary channel 200, thereby being able to balance the temperatures of each area of the battery 2 and reduce the temperature difference of the battery 2.

[0061] Especially for the battery 2 with a long module or an extra-long module, through the temperature regulating plate 1, the middle area of the battery 2 can be locally temperature-regulated, which can not only improve the temperature regulating efficiency, but also make the temperature regulation more accurate.

[0062] In addition, according to the temperature regulation requirements of the battery 2, for example, when the temperature of the battery 2 is higher than the high-temperature preset value, the fluid in the secondary channel 200 can reduce the temperature of the fluid in the main channel 100 to cool the battery 2. At this time, the temperature regulation plate 1 can be used as a liquid cooling plate; when the temperature of the battery 2 is lower than the low-temperature preset value, the fluid in the secondary channel 200 can increase the temperature of the fluid in the main channel 100 to heat the battery 2.

[0063] As a preferred implementation manner, along the flow direction of the temperature regulation fluid, the communication ports 300 of the plurality of secondary channels 200 and the main channel 100 are arranged at intervals from each other. Thereby enabling the secondary channel 200 to act on different regions of the battery 2, balancing the temperature difference in each region of the battery 2, and improving the temperature regulation effect.

[0064] As a preferred implementation manner, the caliber of the main channel 100 is larger than that of the secondary channel 200. Thereby enabling most of the temperature regulation fluid to enter the main channel 100 to mainly dissipate heat from the battery 2; a small part of the temperature regulation fluid enters each secondary channel 200 and mixes with the fluid in the main channel 100 to reduce the temperature of the fluid in the main channel 100, thereby enhancing the temperature regulation ability of the fluid in the main channel 100 for the battery 2 region located downstream of the secondary channel 200.

[0065] As a preferred implementation manner, the caliber of the secondary channel 200 is associated with the temperature of the corresponding battery 2 region downstream. Thereby enabling the improvement of the temperature regulation accuracy.

[0066] In specific implementation, for example, for an ultra-long battery module, the temperature in the middle region is higher than that on both sides. Then, the caliber of the upstream secondary channel 200 corresponding to the middle region can be set larger to allow more fluid to flow through and mix with the fluid in the main channel 100, having a stronger temperature regulation ability for this middle region, enabling the temperature of the battery 2 in the middle region to be adjusted to a greater extent, reducing the temperature difference in each region of the battery 2, and making the overall temperature within the required temperature.

[0067] As a preferred implementation manner, the included angle between the opening direction of the communication port 300 of the secondary channel 200 and the main channel 100 and the flow direction of the temperature regulation fluid in the main channel 100 is an acute angle. Thus, on the one hand, part of the fluid can flow along the flow direction of the fluid after entering from the secondary channel 200; on the other hand, part of the fluid entering from the secondary channel 200 can also disturb the flow field of part of the fluid in the main channel 100, enhancing the heat exchange between the temperature regulation fluid and the temperature regulation plate 1 and improving the temperature regulation performance. Among them, the opening direction of the communication port 300 of the secondary channel 200 and the main channel 100 refers to the axial direction of the secondary channel 200, that is, the flow direction of the temperature regulation fluid in the secondary channel 200.

[0068] The following will be combined withFigure 1 and Figure 2 A temperature control plate 1 provided, and Figures 3-7 Another temperature control plate 1 provided further illustrates the specific implementation manners of the present invention.

[0069] As a preferred implementation manner, as Figure 1 and Figure 2 shown, the body part 10 of the temperature control plate 1 includes a plate body 410 and at least one secondary pipeline 420. The plate body 410 is used for connecting with the battery 2; the main channel 100 is arranged in the plate body 410. A secondary channel 200 is arranged in each secondary pipeline 420. One end of the secondary pipeline 420 is communicated with the inlet 20, and the other end of the secondary pipeline 420 is communicated with the plate body 410.

[0070] As Figure 1 and Figure 2 shown, a structural schematic diagram with two secondary pipelines 420 is shown. One ends of the two secondary pipelines 420 are both communicated with the inlet 20, and one end of the plate body 410 is also communicated with the inlet 20. When the temperature control fluid enters the inlet 20, the temperature control fluid will be divided into three parts. Most of the temperature control fluid will enter the main channel 100 of the plate body 410, and the remaining temperature control fluid will respectively enter the secondary channels 200 in the two secondary pipelines 420. The temperature control fluid entering the plate body 410 will flow towards the outlet 30. The plate body 410 is attached to the outer wall of the battery 2, so as to be able to control the temperature of the battery 2. The temperature control fluid entering the secondary pipeline 420 will be mixed with the temperature control fluid in the plate body 410 at the communication port 300 between it and the plate body 410, so as to control the temperature of the temperature control fluid in the plate body 410, and flow out of the outlet 30 together with the mixed fluid in the plate body 410. Among them, the communication port 300 between the first secondary pipeline 420 and the plate body 410 and the communication port 300 between the second secondary pipeline 420 and the plate body 410 are arranged at intervals.

[0071] For example, the temperature control fluid flows in the plate body 410 to dissipate heat from the battery 2. When the temperature control fluid flows a certain distance, its temperature rises and the heat dissipation capacity decreases; when it flows to the communication port 300 between the first secondary pipeline 420 and the plate body 410, the temperature control fluid with a lower temperature in the first secondary pipeline 420 is mixed with the temperature control fluid in the plate body 410, so that the temperature of the temperature control fluid in the plate body 410 decreases, and thus continue to dissipate heat from the downstream battery 2 area; when the mixed fluid flows a certain distance and flows to the communication port 300 between the second secondary pipeline 420 and the plate body 410, the temperature control fluid with a lower temperature in the second secondary pipeline 420 is further mixed with the mixed fluid, and continue to dissipate heat from the downstream battery 2 area; finally, the mixed fluid flows to the outlet 30 together.

[0072] As Figure 1 shown, the opening direction of the communication port 300 between the secondary channel 200 and the main channel 100 is namelyFigure 1 In the B direction, the flow direction of the temperature-regulating fluid in the main channel 100 is the A direction, and the included angle between the two is α, and this included angle α is an acute angle. When the fluid in the secondary channel 200 enters the main channel 100 through the communication port 300, the fluid in the secondary channel 200 can continue to flow downstream along the flow direction of the fluid in the main channel 100; due to the existence of this included angle α, the fluid in the secondary channel 200 can also disturb the flow field of the fluid in the main channel 100, enhance the heat exchange between the fluid and the temperature-regulating plate 1, and improve the temperature-regulating performance.

[0073] As shown in Figure 2 the figure, the plate body 410, the first secondary pipe 420 and the second secondary pipe 420 are also arranged at intervals in the vertical direction, so as to reduce the heat exchange between the three. Correspondingly, the first secondary pipe 420 and the second secondary pipe 420 can be arranged on the same horizontal plane and are arranged at intervals between them; and both are arranged at intervals with the plate body 410 in the vertical direction, so that the structure of the temperature-regulating plate 1 can be more compact.

[0074] As another preferred embodiment, as shown in Figures 3-7 the figure, the body part 10 of the temperature-regulating plate 1 is a plate-like structure, including a first side wall 510 and a second side wall 520 arranged oppositely, and the first side wall 510 is used for connecting with the battery 2; from the first side wall 510 to the direction of the second side wall 520, the main channel 100 and at least one secondary channel 200 are arranged layer by layer; the main channel 100 is arranged close to the first side wall 510.

[0075] In specific implementation, the body part 10 of the plate-like structure can be adapted to the outer surface of the battery 2, the main channel 100 and the secondary channel 200 are arranged layer by layer, and the temperature-regulating fluid can flow from the inlet 20 and then flow in different layers towards the outlet 30 direction through the distribution of the main channel 100 and the secondary channel 200; among them, the main channel 100 is closer to the battery 2 and can play a main temperature-regulating role on the battery 2, and multiple secondary channels 200 can communicate with the main channel 100 in different layers to play an auxiliary temperature-regulating role.

[0076] As shown in Figure 3 the figure, it is a schematic external structure diagram of the temperature-regulating plate 1 connected with the battery 2, and its inlet 20 and outlet 30 are both connected with the first side wall 510. As shown in Figure 4 the figure, it is a partial internal schematic diagram at the inlet 20 of the temperature-regulating plate 1. From the first side wall 510 to the direction of the second side wall 520, the main channel 100, the first secondary channel 200 and the second secondary channel 200 are arranged layer by layer. After the temperature-regulating fluid enters from the inlet 20, most of it flows into the main channel 100, and the remaining fluid flows into the first secondary channel 200 for a part and into the second secondary channel 200 for the other part. As shown in Figure 5As shown, it is a partial internal schematic diagram at the connection of the first secondary channel 200 and the main channel 100. The temperature-regulating fluid in the first secondary channel 200 enters the main channel 100 through its connection port 300 with the main channel 100, and mixes with the temperature-regulating fluid in the main channel 100 and flows downstream (towards the outlet 30); the temperature-regulating fluid in the second secondary channel 200 flows directly downstream. As Figure 6 shown, it is a partial internal schematic diagram at the connection of the second secondary channel 200 and the main channel 100. The temperature-regulating fluid in the second secondary channel 200 enters the main channel 100 through its connection port 300 with the main channel 100, and mixes with the temperature-regulating fluid in the main channel 100 and flows towards the outlet 30, as Figure 7 shown, it is a partial internal schematic diagram at the outlet 30. The mixed temperature-regulating fluid flows out of the outlet 30.

[0077] As a preferred embodiment, as Figures 4-7 shown, the main channel 100 and the secondary channels 200 are parallel to each other.

[0078] As a preferred embodiment, compared with the connection port 300 of the secondary channel 200 close to the main channel 100 and the main channel 100, the connection port 300 of the secondary channel 200 far from the main channel 100 is closer to the outlet 30. Thus, for the secondary channel 200 farther away from the main channel 100, its connection port 300 with the main channel 100 is closer to the outlet 30, so that a part of the fluid in this secondary channel 200 can be less affected by the temperature of the battery 2. When it flows to the corresponding connection port 300 and mixes with a part of the fluid in the main channel 100, it can still regulate the temperature of the fluid in the main channel 100.

[0079] As Figures 4-7 shown, the main channel 100, the first secondary channel 200, and the second secondary channel 200 are arranged in sequence along the vertical direction, where the main channel 100 is close to the battery 2 and the second secondary channel 200 is far from the battery 2. The connection port 300 of the first secondary channel 200 and the main channel 100 and the connection port 300 of the second secondary channel 200 and the main channel 100 are arranged in sequence along the flow direction of the temperature-regulating fluid; that is, the connection port 300 of the second secondary channel 200 and the main channel 100 is closer to the outlet 30.

[0080] In addition, the opening directions of the connection port 300 of the first secondary channel 200 and the main channel 100 and the opening direction of the connection port 300 of the second secondary channel 200 and the main channel 100 can both form an acute angle with the flow direction of the temperature-regulating fluid in the main channel 100 (not shown in the figure) to produce an effect similar to that in the above-mentioned first temperature-regulating plate 1.

[0081] As a preferred embodiment, as Figures 4-7As shown, the temperature regulating plate 1 further includes at least one partition portion 530. The partition portion 530 is disposed between the first side wall 510 and the second side wall 520, and the partition portion 530 is arranged parallel to the first side wall 510 and the second side wall 520; the communication port 300 of the secondary channel 200 and the main channel 100 is disposed on the partition portion 530.

[0082] By providing the partition portion 530 between the first side wall 510 and the second side wall 520, the corresponding main channel 100 and secondary channel 200 can be configured to distribute and mix the temperature regulating fluid.

[0083] As a preferred embodiment, as Figure 4 and Figure 5 shown, the partition portion 530 includes a partition plate 531 and a clamping plate 532. The partition plate 531 and the clamping plate 532 are mutually attached. The partition plate 531 is used for heat insulation and supporting the clamping plate 532; the secondary channel 200 extends from one end of the clamping plate 532 to the corresponding position of the communication port 300.

[0084] The embodiment of the present invention further provides a temperature regulating device. The temperature regulating device includes the temperature regulating plate 1 as described above, and there is at least one temperature regulating plate 1; the battery 2 has a plurality of battery modules, and the temperature regulating plate 1 corresponds to at least one battery module.

[0085] After the temperature regulating fluid enters from the inlet 20, part of the fluid enters one end of the main channel 100, and part of the fluid enters one end of the secondary channel 200. The other end of the secondary channel 200 is communicated with the main channel 100. The part of the fluid entering the secondary channel 200 flows into the main channel 100 from the other end of the secondary channel 200 and is mixed with the fluid in the main channel 100; thus, through the temperature regulating plate 1 in this solution, the temperature regulating fluid can be distributed, so that part of the fluid passes through the main channel 100 to perform overall temperature regulation on the battery 2, and part of the fluid is mixed with the fluid in the main channel 100 at each secondary channel 200, so that the corresponding area downstream of the battery 2 can be temperature-regulated under the action of part of the fluid in the secondary channel 200, thereby being able to balance the temperatures of each area of the battery 2 and reduce the temperature difference of the battery 2.

[0086] As a preferred embodiment, a plurality of battery modules are arranged in sequence, and a plurality of temperature regulating plates 1 are arranged in sequence along the length direction of the battery 2, and the main channels 100 of two adjacent temperature regulating plates 1 are communicated with each other;
