Description

Technical Field

[0002] In order to reduce the control cost of liquid cooling heat dissipation, energy storage containers generally perform liquid cooling heat dissipation control according to a preset fixed scheme.

[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application. In addition, in the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically defined.

[0035] To improve the accuracy of the test results of the liquid cooling heat dissipation solution, the embodiments of the present application provide a liquid cooling heat dissipation test device and system. In the physical liquid cooling heat dissipation test device, a required liquid cooling heat dissipation solution is simulated by using a liquid cooler and a plurality of flow regulating valves, and the liquid cooling flow rates in a plurality of first liquid cooling branches arranged in parallel are collected by using a plurality of first flowmeters to obtain the actual liquid supply flow rates of different branches of the liquid cooling pipeline, providing accurate data support for the test optimization of the liquid cooling heat dissipation solution and improving the accuracy of the test results. For the specific solution, please refer to the following specific description.

[0036] In a first aspect, the embodiments of the present application provide a liquid cooling heat dissipation test device. Specifically, referring to Figure 1 and Figure 2 , Figure 1 is a schematic diagram of an embodiment of the overall structure of the liquid cooling heat dissipation test device, Figure 2 is another schematic diagram of the overall structure of the liquid cooling heat dissipation test device provided by the embodiments of the present application. In Figure 1 and Figure 2 , the liquid cooling heat dissipation test device may include a liquid cooler 10, a liquid cooling pipeline 20, a plurality of flow regulating valves 40, and a plurality of first flowmeters 50.

[0037] The liquid chiller 10 is used to supply a liquid cooling medium, such as water, to the liquid cooling pipeline 20. The liquid chiller 10 includes a liquid cooling outlet and a liquid cooling return port. The liquid cooling outlet is communicated with the liquid cooling return port through the liquid cooling pipeline 20. The liquid chiller 10 can output the liquid cooling medium from the liquid cooling outlet to the liquid cooling pipeline 20, and the liquid cooling medium output to the liquid cooling pipeline 20 flows back to the liquid chiller 10 through the liquid cooling return port, realizing the circulating flow of the liquid cooling medium. The liquid chiller 10 can receive a control instruction and output a liquid cooling medium with a specified supply temperature and supply flow rate, so as to adjust the liquid cooling heat dissipation capacity of the liquid cooling heat dissipation test device.

[0038] The liquid cooling pipeline 20 may include a plurality of liquid cooling branches, such as a plurality of first liquid cooling branches 21 arranged in parallel. A liquid cooling plate 30 is connected in series in each first liquid cooling branch 21. The liquid cooling plate 30 is a heat exchange plate, and the liquid cooling plate 30 is used to fit with at least one battery module in the energy storage container to be produced. The liquid cooling plate 30 may be arranged in the battery insertion box, and at least one slot is arranged in the battery insertion box. When at least one battery module in the energy storage container to be produced is inserted into the slot, the battery module can be fitted with the liquid cooling plate 30. By fitting the liquid cooling plate 30 with the battery module, the temperature of the battery module is reduced and dissipated.

[0039] A flow regulating valve 40 is arranged in each first liquid cooling branch 21. By adjusting the opening degree of the flow regulating valve 40, the maximum liquid cooling flow rate actually allowed to pass through the first liquid cooling branch 21 is restricted. For example, according to the expected liquid cooling flow rate of the first liquid cooling branch 21 in the liquid cooling heat dissipation scheme to be tested, the opening degree of the flow regulating valve 40 can be adjusted so that the maximum liquid cooling flow rate actually allowed to pass through the first liquid cooling branch 21 is equal to the expected liquid cooling flow rate. It can be seen that adjusting the opening degree of the flow regulating valve 40 is equivalent to adjusting the actual pipeline size of the first liquid cooling branch 21, so that the actual pipeline size of the first liquid cooling branch 21 matches the expected liquid cooling flow rate.

[0040] A first flow meter 50 is arranged in each first liquid cooling branch 21. The first flow meter 50 is used to collect the liquid cooling flow rate actually passing through the first liquid cooling branch 21 where the first flow meter 50 is located. Since there are certain differences between the supply flow rates of different branches of the liquid cooling pipeline 20 when the liquid cooling heat dissipation scheme is applied to the actual energy storage container product, this difference will also be reflected in the liquid cooling flow rates actually passing through the plurality of first liquid cooling branches 21 in the liquid cooling heat dissipation test device. By collecting the liquid cooling flow rates actually passing through the plurality of first liquid cooling branches 21 through the plurality of first flow meters 50, the differences between the liquid cooling flow rates actually passing through the plurality of first liquid cooling branches 21 can be known, providing accurate data support for the test and optimization of the liquid cooling heat dissipation scheme.

[0041] Provide accurate data support for the test and optimization of the liquid cooling heat dissipation solution. For example, it may include the following steps: Based on the liquid cooling flow rates actually passing through multiple first liquid cooling branches 21 collected by multiple first flow meters 50, adjust the simulation model of the energy storage container to be produced, so that the liquid supply flow rates of different branches of the liquid cooling pipeline in the simulation model match the liquid cooling flow rates of multiple first liquid cooling branches 21 collected by multiple first flow meters 50, and achieve the correction of the simulation model. In this way, the test results of the liquid cooling heat dissipation solution obtained in the corrected simulation model will also be more accurate.

[0042] Provide accurate data support for the test and optimization of the liquid cooling heat dissipation solution. Another example may include the following steps: Through the adjustment of the liquid chiller 10 and multiple flow regulating valves 40, test the liquid cooling heat dissipation solution with better heat dissipation effect (the liquid cooling heat dissipation solution with better heat dissipation effect includes the liquid supply flow rate and liquid supply temperature of the liquid chiller 10, and the liquid cooling flow rates of multiple first liquid cooling branches 21 when the battery temperatures of the battery modules attached to each liquid cooling plate 30 meet the corresponding battery temperature preset conditions); Use the liquid cooling heat dissipation solution with better heat dissipation effect as the liquid cooling heat dissipation solution after test and optimization. In this way, the manufacturer of the energy storage container can produce the energy storage container based on the liquid cooling heat dissipation solution after test and optimization.

[0043] Among them, due to cost considerations, flow regulating valves 40 will not be installed in each branch of the liquid cooling pipeline in the produced energy storage container. Therefore, during the production of the energy storage container based on the liquid cooling heat dissipation solution after test and optimization, it is necessary to control the pipeline sizes of each branch of the liquid cooling pipeline in the produced energy storage container to ensure that the maximum liquid cooling flow rate actually allowed to pass through multiple first liquid cooling branches 21 in the produced energy storage container matches the liquid cooling flow rates of multiple first liquid cooling branches 21 in the liquid cooling heat dissipation solution after test and optimization. And, in the liquid cooling heat dissipation control strategy of the produced energy storage container, the actual liquid supply flow rate of the liquid chiller 10 needs to be equal to the liquid supply flow rate of the liquid chiller 10 in the liquid cooling heat dissipation solution after test and optimization, and the actual liquid supply temperature of the liquid chiller 10 needs to be equal to the liquid supply temperature of the liquid chiller 10 in the liquid cooling heat dissipation solution after test and optimization, so that the liquid cooling heat dissipation effect of the produced energy storage container is consistent with the liquid cooling heat dissipation solution after test and optimization.

[0044] It can be seen that in the embodiment of the present application, in the physical liquid cooling heat dissipation test device, the required liquid cooling heat dissipation solution is simulated by using the liquid chiller 10 and multiple flow regulating valves 40, and the liquid cooling flow rates in multiple first liquid cooling branches 21 arranged in parallel are collected by multiple first flow meters 50 to obtain the actual liquid supply flow rates of different branches of the liquid cooling pipeline 20, providing accurate data support for the test and optimization of the liquid cooling heat dissipation solution and improving the accuracy of the test results.

[0045] In some embodiments of the present application, since the flow rate of the liquid cooling medium flowing out of the liquid chiller 10 is usually large, while the flow rate of the liquid cooling medium required for each first liquid cooling branch 21 is usually small, the liquid cooling pipeline 20 can be designed as a multi-stage pipeline structure. Specifically, referring to Figure 2 , the liquid cooling pipeline 20 further includes a plurality of second liquid cooling branches 22 arranged in parallel, each second liquid cooling branch 22 communicates with a plurality of first liquid cooling branches 21, and the plurality of first liquid cooling branches 21 communicated by different second liquid cooling branches 22 are different. It can be seen that the second liquid cooling branch 22 is the upper-stage pipeline of the first liquid cooling branch 21, and the liquid cooling medium passing through each second liquid cooling branch 22 can flow to the plurality of first liquid cooling branches 21 communicated with this second liquid cooling branch 22 respectively, so as to facilitate the diversion of the liquid cooling medium.

[0046] Similarly, referring to Figure 2 , the liquid cooling pipeline 20 further includes a plurality of third liquid cooling branches 23 arranged in parallel, and each third liquid cooling branch 23 communicates with a plurality of second liquid cooling branches 22, and the plurality of second liquid cooling branches 22 communicated by different third liquid cooling branches 23 are different. It can be seen that the third liquid cooling branch 23 is the upper-stage pipeline of the second liquid cooling branch 22, and the liquid cooling medium passing through each third liquid cooling branch 23 can flow to the plurality of second liquid cooling branches 22 communicated with this third liquid cooling branch 23 respectively, so as to facilitate the diversion of the liquid cooling medium.

[0047] In some embodiments of the present application, referring to Figure 2 , the plurality of first liquid cooling branches 21 communicated by each second liquid cooling branch 22 are sequentially distributed along the liquid cooling flow direction in this second liquid cooling branch 22, that is, the plurality of first liquid cooling branches 21 are sequentially connected to different positions of the second liquid cooling branch 22 along the liquid cooling flow direction in the second liquid cooling branch 22, so that the connection positions of the plurality of first liquid cooling branches 21 on the second liquid cooling branch 22 are relatively dispersed, which is convenient for the production of energy storage container products. Similarly, referring to Figure 2 , the plurality of second liquid cooling branches 22 communicated by each third liquid cooling branch 23 are sequentially distributed along the liquid cooling flow direction in this third liquid cooling branch 23, that is, the plurality of second liquid cooling branches 22 are sequentially connected to different positions of the third liquid cooling branch 23 along the liquid cooling flow direction in the third liquid cooling branch 23, so that the connection positions of the plurality of second liquid cooling branches 22 on the third liquid cooling branch 23 are relatively dispersed, which is convenient for the production of energy storage container products.

[0048] In some embodiments of the present application, since the number of first liquid cooling branches 21 in the liquid cooling and heat dissipation test device is large, while the number of battery modules in the actually required energy storage container to be produced may be small, resulting in that some first liquid cooling branches 21 in the liquid cooling and heat dissipation test device do not need to be used. In order to close these unused first liquid cooling branches 21, referring to Figure 2, at least one two-way valve 60 is provided in the third liquid cooling branch 23, and the working states of the two-way valve 60 include an open state and a closed state. When the two-way valve 60 is in the open state, the liquid cooling medium cannot pass through the third liquid cooling branch 23. When the two-way valve 60 is in the closed state, the liquid cooling medium can pass through the third liquid cooling branch 23. Therefore, by controlling the two-way valve 60, the working state of the two-way valve 60 can be switched, so that the liquid cooling medium can or cannot pass through the third liquid cooling branch 23. For example, when some of the first liquid cooling branches 21 do not need to be used, the two-way valves 60 in the third liquid cooling branches 23 connected to the second liquid cooling branches 22 connected to these first liquid cooling branches 21 can be controlled, so that the working state of the two-way valve 60 is the closed state. In this way, the liquid cooling medium will not pass through these first liquid cooling branches 21 that do not need to be used, and they will be closed at the same time. It can be seen that by the two-way valve 60 in the third liquid cooling branch 23, these first liquid cooling branches 21 that do not need to be used can be quickly closed.

[0049] In some embodiments of the present application, referring to Figure 2 , similar to the multiple second liquid cooling branches 22 arranged in parallel, the liquid cooling pipeline 20 further includes multiple second liquid cooling loops 24 arranged in parallel. Each second liquid cooling loop 24 is connected to multiple first liquid cooling branches 21, and the multiple first liquid cooling branches 21 connected by different second liquid cooling loops 24 are different. From Figure 2 it can be seen that each second liquid cooling branch 22 is respectively connected to a second liquid cooling loop 24 through multiple first liquid cooling branches 21, so that the liquid cooling medium in each second liquid cooling branch 22 flows into a second liquid cooling loop 24 through multiple first liquid cooling branches 21 respectively. In addition, the multiple first liquid cooling branches 21 connected to each second liquid cooling loop 24 are sequentially distributed along the liquid cooling flow direction in the second liquid cooling loop 24, that is, the multiple first liquid cooling branches 21 are sequentially connected to different positions of the second liquid cooling loop 24 along the liquid cooling flow direction in the second liquid cooling loop 24, so that the connection positions of the multiple first liquid cooling branches 21 on the second liquid cooling loop 24 are relatively dispersed, which is convenient for the production of energy storage container products.

[0050] In some embodiments of the present application, referring to Figure 2 , similar to the multiple third liquid cooling branches 23 arranged in parallel, the liquid cooling pipeline 20 further includes multiple third liquid cooling loops 25 arranged in parallel. Each third liquid cooling loop 25 is connected to multiple second liquid cooling loops 24, and the multiple second liquid cooling loops 24 connected by different third liquid cooling loops 25 are different. From Figure 2It can be seen that the liquid cooling medium in each second liquid cooling loop 24 can flow into a third liquid cooling loop 25, and the liquid cooling medium in multiple third liquid cooling loops 25 can flow back to the liquid chiller 10 through the liquid cooling return port of the liquid chiller 10, realizing the circulating flow of the liquid cooling medium. In addition, multiple second liquid cooling loops 24 connected to each third liquid cooling loop 25 are sequentially distributed along the liquid cooling flow direction in the third liquid cooling loop 25, that is, multiple second liquid cooling loops 24 are sequentially connected to different positions of the third liquid cooling loop 25 along the liquid cooling flow direction in the third liquid cooling loop 25, so that the connection positions of multiple second liquid cooling loops 24 on the third liquid cooling loop 25 are relatively dispersed, facilitating the production of energy storage container products.

[0051] In some embodiments of the present application, for the third liquid cooling branch 23 provided with the two-way valve 60, the two-way valve 60 and multiple second liquid cooling branches 22 connected to each third liquid cooling branch 23 are sequentially distributed along the liquid cooling flow direction in the third liquid cooling branch 23, that is, in the third liquid cooling branch 23, the liquid cooling medium first flows through the installation position of the two-way valve 60, and then flows through the connection positions of multiple second liquid cooling branches 22 and the third liquid cooling branch 23. In this way, by controlling the working state of the two-way valve 60, the closing of all second liquid cooling branches 22 connected to the third liquid cooling branch 23 can be controlled.

[0052] In some embodiments of the present application, referring to Figure 3 , the liquid cooling and heat dissipation test device may further include multiple second flow meters 70, and each second flow meter 70 is arranged in a second liquid cooling branch 22. For example, a second flow meter 70 can be arranged in each second liquid cooling branch 22, and the second flow meter 70 is used to collect the liquid cooling flow rate in the second liquid cooling branch 22. Moreover, the second flow meter 70 and multiple first liquid cooling branches 21 connected to each second liquid cooling branch 22 are sequentially distributed along the liquid cooling flow direction in the second liquid cooling branch 22, that is, the liquid cooling flow rates passing through all first liquid cooling branches 21 connected to the second liquid cooling branch 22 will be collected by the second flow meter 70. By collecting the actual liquid cooling flow rates passing through multiple second liquid cooling branches 22 with multiple second flow meters 70, the differences between the actual liquid cooling flow rates passing through multiple second liquid cooling branches 22 can be known, providing accurate data support for the test and optimization of the liquid cooling and heat dissipation scheme.

[0053] In some embodiments of the present application, the flow regulating valve 40 and the liquid cooling plate 30 connected to each first liquid cooling branch 21 are sequentially distributed along the liquid cooling flow direction in the first liquid cooling branch 21, that is, in each first liquid cooling branch 21, the liquid cooling medium first flows through the flow regulating valve 40 and then through the liquid cooling plate 30, so as to facilitate the flow regulating valve 40 to control all liquid cooling flow rates passing through the liquid cooling plate 30.

[0054] In some embodiments of the present application, the liquid cooling heat dissipation test device further includes a plurality of temperature acquisition units, and each temperature acquisition unit is used to acquire the battery temperature of a battery module. The temperature acquisition unit can be arranged, for example, in the above-mentioned battery insertion box. By setting the position of the temperature acquisition unit in the battery insertion box, when the battery module is inserted into the battery insertion box, the battery temperature of the battery module can be acquired by the temperature acquisition unit in the battery insertion box. Based on the battery temperature acquired by the temperature acquisition unit, it can be determined whether the actual heat dissipation effect of the current liquid cooling heat dissipation solution is good, so as to obtain a liquid cooling heat dissipation solution with a good heat dissipation effect.

[0055] In some embodiments of the present application, in order to facilitate the control of the liquid cooling heat dissipation test device, the liquid cooling heat dissipation test device may further include a parameter input unit and a parameter output unit, and the parameter input unit and the parameter output unit can be integrated in the upper computer of the liquid cooling heat dissipation test device.

[0056] The parameter input unit is used to receive control instructions for at least one flow regulating valve 40 and receive control instructions for the liquid chiller 10. For example, the control instructions for at least one flow regulating valve 40 can be input into the parameter input unit, so that the parameter input unit adjusts the opening degree of the corresponding flow regulating valve 40 in the liquid cooling heat dissipation test device according to the received control instructions for at least one flow regulating valve 40. For another example, the control instructions for the liquid chiller 10 can be input into the parameter input unit, so that the parameter input unit controls the liquid chiller 10 in the liquid cooling heat dissipation test device to output the liquid cooling medium from the liquid cooling outlet according to the specified liquid supply flow rate and liquid supply temperature. Among them, the control instructions for at least one flow regulating valve 40 and the control instructions for the liquid chiller 10 can be determined based on the liquid cooling heat dissipation solution to be simulated. In this way, the corresponding liquid cooling heat dissipation solution can be simulated in the liquid cooling heat dissipation test device, and the heat dissipation effect test of the liquid cooling heat dissipation solution can be realized.

[0057] The parameter output device is used to output the battery temperatures acquired by the plurality of temperature acquisition units and the liquid cooling flow rates acquired by the plurality of first flow meters 50. Based on the plurality of battery temperatures output by the parameter output device, it can be determined whether the actual heat dissipation effect of the current liquid cooling heat dissipation solution is good, and when the actual heat dissipation effect of the current liquid cooling heat dissipation solution is good, the plurality of liquid cooling flow rates currently output by the parameter output device are used as the liquid cooling flow rates actually passed by the plurality of first liquid cooling branches 21 in the liquid cooling heat dissipation solution with a good heat dissipation effect, so as to obtain a liquid cooling heat dissipation solution with a good heat dissipation effect.

[0058] In some embodiments of the present application, refer to Figure 4, a first thermometer 11 and a pressure gauge 12 are provided at the liquid cooling outlet of the liquid chiller 10, and a second thermometer 13 and a third flowmeter 14 are provided at the liquid cooling return port of the liquid chiller 10. External parameters such as the supply liquid temperature at the liquid cooling outlet collected by the first thermometer 11, the supply liquid pressure at the liquid cooling outlet collected by the pressure gauge 12, the supply liquid temperature at the liquid cooling return port collected by the second thermometer 13, and the supply liquid flow rate at the liquid cooling return port collected by the third flowmeter 14 are used to be input into the liquid chiller 10, so that the liquid chiller 10 controls its internal operating parameters based on these external parameters, so that the actual supply liquid flow rate of the liquid chiller 10 reaches the specified supply liquid flow rate, and the actual supply liquid temperature of the liquid chiller 10 reaches the specified supply liquid temperature.

[0059] In a second aspect, based on the liquid cooling heat dissipation test device in the above embodiment, an embodiment of the present application provides a liquid cooling heat dissipation test system. Refer to Figure 5 , the liquid cooling heat dissipation test system includes the liquid cooling heat dissipation test device described in any one of the above, and a plurality of battery modules.

Specific examples are used in this article to elaborate on the structure and implementation manner of the present application. The description of the above embodiments is only used to help understand the structure and core idea of the present application; at the same time, for those skilled in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope.
