Description

Technical Field

[0001] The present application relates to the field of energy storage technology, and in particular to an energy storage liquid cooling system and a high-temperature starting method thereof, an electronic device and a storage medium. Background Art

[0002] When using a liquid cooling system to dissipate heat from an energy storage container, the low-pressure refrigerant on the compressor of the liquid cooling system is generally used to absorb the heat of the energy storage container, and the heat is dissipated outwards through the high-pressure refrigerant on the compressor, thereby reducing the temperature of the energy storage container. However, in a high-temperature environment, the temperature of the energy storage container itself may be too high, causing the low-pressure refrigerant on the compressor to absorb too much heat, resulting in the high-pressure refrigerant pressure on the high-pressure side of the compressor being too high, triggering the high-temperature protection mechanism of the compressor, and causing the high-temperature startup of the liquid cooling system to fail.

[0003] In the related art, a more heat-resistant refrigerant is usually used in the liquid cooling system to avoid high-temperature startup failure of the liquid cooling system, for example, the R410a refrigerant is replaced with the more heat-resistant R134a refrigerant. However, after using a more heat-resistant refrigerant, other components in the liquid cooling system also need to be replaced accordingly, and the power consumption of the liquid cooling system is also higher, which increases the cost of the liquid cooling system.

[0047] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. In addition, in the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically limited.

[0048] In order to reduce the cost of the energy storage liquid cooling system while ensuring that the energy storage liquid cooling system can be started at high temperature, the embodiment of the present application provides an energy storage liquid cooling system and a high temperature starting method thereof, an electronic device and a storage medium, by adding a pipeline between the liquid cooling outlet of the energy storage container and the liquid storage tank, when the compressor needs to be started at high temperature, the pipeline connecting the liquid cooling outlet of the energy storage container to the liquid storage tank is first controlled to be conductive, so that part of the refrigerant flowing out of the energy storage container does not flow through the heat exchanger and directly enters the liquid storage tank, so as to avoid the refrigerant on the low-pressure side of the compressor absorbing too much heat and the refrigerant pressure on the high-pressure side of the compressor is too high, thereby achieving high temperature starting of the energy storage liquid cooling system, and the cost of the energy storage liquid cooling system is lower. Please refer to the following specific description for the specific scheme.

[0049] In a first aspect, an embodiment of the present application provides an energy storage liquid cooling system. Specifically, referring to Figure 1 , Figure 1 This is a schematic diagram of an embodiment of the overall structure of the energy storage liquid cooling system. Figure 1 In the embodiment, the energy storage liquid cooling system may include a refrigeration circuit and a liquid cooling circuit connected in parallel via a heat exchanger 10 .

[0050] The heat exchanger 10 may be, for example, a plate heat exchanger. The heat exchanger 10 includes a first heat exchange pipe and a second heat exchange pipe arranged in parallel, and the refrigerant in the first heat exchange pipe and the refrigerant in the second heat exchange pipe can exchange heat in the heat exchanger 10. The first heat exchange pipe is arranged in a refrigeration circuit, and the second heat exchange pipe is arranged in a liquid cooling circuit.

[0051] In the refrigeration circuit, in addition to the first heat exchange pipe, a compressor 21 is also included, and the compressor 21 is connected to the first heat exchange pipe. In the refrigeration circuit, components such as a condenser 22, a condensation fan 23, a drying filter 24, and an expansion valve 25 may also be included. In the refrigeration circuit, the heat exchanger 10 is equivalent to an evaporator, which is used to absorb heat using a refrigerant, while the condenser 22 is used to dissipate heat to the outside using a refrigerant, and the condensation fan 23 is used to drive air flow, so that the condenser 22 can dissipate heat to the outside air. The refrigeration principle of the refrigeration circuit is similar to that of an air conditioner, and will not be repeated here.

[0052] In the liquid cooling circuit, in addition to the second heat exchange pipe, a liquid storage tank 31 is also included, and the liquid cooling outlet of the energy storage container 32 is respectively connected to the heat exchanger 10 and the liquid storage tank 31. Specifically, the liquid cooling outlet of the energy storage container 32 is respectively connected to the inlet of the second heat exchange pipe in the heat exchanger 10 and a liquid inlet of the liquid storage tank 31. The outlet of the second heat exchange pipe in the heat exchanger 10 is also connected to the liquid inlet of the liquid storage tank 31, and in the liquid storage tank 31, the liquid inlet connected to the outlet of the second heat exchange pipe in the heat exchanger 10 and the liquid inlet connected to the liquid cooling outlet of the energy storage container 32 can be the same liquid inlet or different liquid inlets, which is not limited here.

[0053] The pipe used to connect the liquid cooling outlet of the energy storage container 32 and the liquid inlet of the liquid storage tank 31 is the target pipe. A target valve 33 is connected in series in the target pipe, and the target valve 33 can be, for example, a proportional two-way valve. The target valve 33 can be used to control the conduction and closing of the target pipe, as well as to control the current conduction opening of the target pipe. Therefore, the high-temperature start-up method of the energy storage liquid cooling system can be executed by controlling the conduction of the target pipe, so as to ensure that the energy storage liquid cooling system can be started at high temperature.

[0054] In the liquid cooling circuit, the liquid outlet of the liquid storage tank 31 is connected to the liquid cooling inlet of the energy storage container 32, so as to facilitate the circulation of the refrigerant in the liquid cooling circuit. In addition, in the liquid cooling circuit, a liquid supply pump 34 is also provided in the pipeline connecting the liquid outlet of the liquid storage tank 31 and the liquid cooling inlet of the energy storage container 32, and the liquid supply pump 34 is used to drive the flow of the refrigerant in the liquid cooling circuit.

[0055] In a second aspect, an embodiment of the present application provides a high temperature startup method for an energy storage liquid cooling system. The high temperature startup method for an energy storage liquid cooling system is performed based on the energy storage liquid cooling system. Specifically, refer to Figure 2 ,exist Figure 1 Based on the embodiment shown, Figure 2 The figure is a flow chart of an embodiment of a high temperature startup method for an energy storage liquid cooling system. Figure 2 In the method for high temperature startup of the energy storage liquid cooling system, the method may include:

[0056] 201. When a power-on instruction for an energy storage container is received, the ambient temperature of the energy storage container is obtained.

[0057] In the embodiment of the present application, the power-on instruction for the energy storage container refers to an instruction for instructing to start the energy storage container, and the instruction can be triggered manually or automatically. The ambient temperature of the energy storage container refers to the temperature of the environment in which the energy storage container is located, for example, it can be at least one of the external ambient temperature and the internal ambient temperature of the energy storage container body.

[0058] In some embodiments of the present application, after obtaining the ambient temperature of the energy storage container, it may also include: when the ambient temperature is greater than or equal to the ambient temperature threshold, it indicates that if the compressor is started at this time, the compressor may be in a high-temperature start-up condition, so step 202 is executed to obtain the liquid supply temperature of the liquid cooling circuit. When the ambient temperature is less than the ambient temperature threshold, it indicates that if the compressor is started at this time, the compressor will not be in a high-temperature start-up condition, so the compressor can be directly started to achieve the liquid cooling heat dissipation effect of the energy storage liquid cooling system.

[0059] In addition, when the ambient temperature is greater than or equal to the ambient temperature threshold, the liquid supply pump in the energy storage liquid cooling system can also be started to drive the refrigerant in the liquid cooling circuit to circulate through the liquid supply pump to utilize the refrigerant for liquid cooling and heat dissipation.

[0060] 202. Obtain the liquid supply temperature of the liquid cooling circuit.

[0061] In the embodiments of the present application, the liquid supply temperature of the liquid cooling circuit refers to the refrigerant temperature at locations such as the liquid supply pump outlet, the liquid cooling inlet of the energy storage container, and the liquid cooling outlet of the energy storage container.

[0062] 203. When the ambient temperature is greater than or equal to the ambient temperature threshold, control the target pipeline connecting the liquid cooling outlet of the energy storage container to the liquid storage tank to be conductive.

[0063] In an embodiment of the present application, the ambient temperature threshold and the first liquid supply temperature threshold are preset values, and the ambient temperature threshold may be, for example, 50°C, and the first liquid supply temperature threshold may be, for example, 40°C. When the ambient temperature is greater than or equal to the ambient temperature threshold, and the liquid supply temperature is greater than or equal to the first liquid supply temperature threshold, it indicates that if the compressor is started at this time, the compressor will be in a high-temperature start-up condition, and the energy storage liquid cooling system may fail to start at high temperature. Therefore, the target pipeline can be controlled to be connected so that part of the refrigerant flowing out of the liquid cooling outlet of the energy storage container can flow directly from the target pipeline connected to the liquid inlet of the liquid storage tank from the liquid cooling outlet of the energy storage container to the liquid storage tank without passing through the heat exchanger, and then flow back from the liquid storage tank to the energy storage container. It can be seen that by controlling the conduction of the target pipeline, the refrigerant flow that needs to flow through the second heat exchange pipeline can be reduced, so that the heat that the heat exchanger needs to exchange between the first heat exchange pipeline and the second heat exchange pipeline will also be reduced, and the heat absorbed by the low-pressure side refrigerant of the compressor will also be reduced to lower the high-pressure side refrigerant pressure of the compressor.

[0064] In some embodiments of the present application, after step 203, it may also include: starting the condensing fan of the condenser in the refrigeration circuit; after the condensing fan is turned on, executing step 204 to accelerate the rate at which the condenser dissipates heat to the outside through the operation of the condensing fan, reduce the refrigerant pressure on the high-pressure side and the refrigerant pressure on the low-pressure side of the compressor, so that the energy storage liquid cooling system can be started up faster at high temperature.

[0065] In some embodiments of the present application, after obtaining the liquid supply temperature of the liquid cooling circuit, it can also include: when the liquid supply temperature is less than the first liquid supply temperature threshold, it indicates that if the compressor is started at this time, the compressor will not be in a high-temperature starting condition, so the compressor can be started directly to achieve the liquid cooling heat dissipation effect of the energy storage liquid cooling system.

[0066] 204. Start the compressor in the refrigeration circuit.

[0067] In an embodiment of the present application, the compressor is started after the target pipeline is controlled to be open, which can avoid excessive refrigerant pressure on the high-pressure side of the compressor, thereby ensuring that the compressor can be successfully started under high temperature conditions.

[0068] It can be seen that in the above-mentioned embodiment of the present application, by adding a pipeline between the liquid cooling outlet of the energy storage container and the liquid storage tank, when the compressor needs to be started at high temperature, the pipeline connecting the liquid cooling outlet of the energy storage container to the liquid storage tank is first controlled to be conductive, so that part of the refrigerant flowing out of the energy storage container does not flow through the heat exchanger and directly enters the liquid storage tank, so as to avoid the refrigerant on the low-pressure side of the compressor absorbing too much heat and the refrigerant pressure on the high-pressure side of the compressor is too high, thereby achieving high-temperature start-up of the energy storage liquid cooling system, and the cost of the energy storage liquid cooling system is lower.

[0069] In some embodiments of the present application, Figure 3 As shown, in Figure 2 Based on the embodiment shown, after starting the compressor in the refrigeration circuit, the following steps may also be included:

[0070] 301. Re-obtain the liquid supply temperature of the liquid cooling circuit.

[0071] In the embodiment of the present application, after starting the compressor, the energy storage liquid cooling system needs to be gradually adjusted to a normal state to restore the original liquid cooling heat dissipation effect of the energy storage liquid cooling system. Therefore, after starting the compressor, the liquid supply temperature of the liquid cooling circuit can be re-obtained to control the conduction and closing of the target pipeline based on the re-obtained liquid supply temperature.

[0072] 302. If the liquid supply temperature is lower than a second liquid supply temperature threshold, the target pipeline is controlled to be closed.

[0073] In an embodiment of the present application, a second liquid supply temperature threshold is also provided, and the second liquid supply temperature threshold is less than or equal to the first liquid supply temperature threshold. The second liquid supply temperature threshold may be, for example, 35°C. If the reacquired liquid supply temperature is less than the second liquid supply temperature threshold, it indicates that the energy storage liquid cooling system has completed high-temperature startup, and therefore the target pipeline may be controlled to be closed to restore the original liquid cooling effect of the energy storage liquid cooling system. It can be seen that by setting the second liquid supply temperature threshold to be less than or equal to the first liquid supply temperature threshold, it can be ensured that the high-temperature protection mechanism of the compressor will not be triggered due to the control of the target pipeline closure, thereby preventing the compressor from shutting down again after the target pipeline is closed.

[0074] 303. Control the batteries in the energy storage container to enter an operating state.

[0075] In an embodiment of the present application, after the target pipeline is controlled to be closed, the energy storage container can be controlled to start running, for example, the battery in the energy storage container is controlled to enter an operating state, so that the battery in the energy storage container starts charging and discharging, etc., to realize the charging and discharging function of the energy storage container.

[0076] In some embodiments of the present application, after reacquiring the liquid supply temperature of the liquid cooling circuit, the method may further include: if the reacquired liquid supply temperature is greater than or equal to a second liquid supply temperature threshold, maintaining the current conduction opening of the target pipeline.

[0077] In some embodiments of the present application, after reacquiring the liquid supply temperature of the liquid cooling circuit, it may also include: if the reacquired liquid supply temperature is greater than or equal to the second liquid supply temperature threshold, adjusting the current conduction opening of the target pipeline based on the liquid supply temperature to gradually restore the original liquid cooling and heat dissipation effect of the energy storage liquid cooling system. Among them, the current conduction opening of the target pipeline is positively correlated with the reacquired liquid supply temperature. It can be understood that since the reacquired liquid supply temperature will gradually decrease due to the heat exchange performed in the heat exchanger, the current conduction opening of the target pipeline can also be gradually reduced, thereby gradually restoring the original liquid cooling and heat dissipation effect of the energy storage liquid cooling system.

[0078] In some embodiments of the present application, Figure 4 As shown, in Figure 2 or Figure 3 On the basis of the illustrated embodiment, when the ambient temperature is greater than or equal to the ambient temperature threshold and the liquid supply temperature is greater than or equal to the first liquid supply temperature threshold, controlling the target pipeline connecting the liquid cooling outlet of the energy storage container to the liquid storage tank may include:

[0079] 401. When the ambient temperature is greater than or equal to an ambient temperature threshold, and the liquid supply temperature is greater than or equal to a first liquid supply temperature threshold, obtain a target conductance opening of a target pipeline.

[0080] 402. Control the conductance of the target pipeline according to the target conductance opening.

[0081] In the embodiment of the present application, the target conductance opening of the target pipeline refers to the target value of the conductance opening of the target pipeline. The target conductance opening can be a preset value, such as 100%, 90%, and in order to avoid high temperature startup failure of the energy storage liquid cooling system as much as possible, the target conductance opening is generally set to 100%.

[0082] Of course, the target conduction opening may not be a preset value, but may be determined based on the liquid supply temperature. Specifically, obtaining the target conduction opening of the target pipeline may include: obtaining the difference between the liquid supply temperature and the first liquid supply temperature threshold; and determining the target conduction opening of the target pipeline based on the difference. The target conduction opening of the target pipeline is positively correlated with the difference, that is, the greater the liquid supply temperature, the greater the target conduction opening, thereby avoiding the high-temperature startup failure of the energy storage liquid cooling system while ensuring that the energy storage liquid cooling system has a certain degree of liquid cooling heat dissipation effect.

[0083] In some embodiments of the present application, the refrigerant in the above embodiments may be a refrigerant of model R410a.

[0084] In a third aspect, based on the high temperature startup method of the energy storage liquid cooling system of the above embodiment, an embodiment of the present application provides a high temperature startup device of the energy storage liquid cooling system, and the high temperature startup device of the energy storage liquid cooling system is used to perform the steps in any embodiment of the high temperature startup method of the energy storage liquid cooling system. For example, the high temperature startup device of the energy storage liquid cooling system may include:

[0085] A first acquisition module is used to acquire the ambient temperature of the energy storage container when receiving a startup instruction for the energy storage container;

[0086] A second acquisition module is used to obtain the liquid supply temperature of the liquid cooling circuit;

[0087] A valve regulating module, used to control the target pipeline connecting the liquid cooling outlet of the energy storage container to the liquid storage tank to be conductive when the ambient temperature is greater than or equal to the ambient temperature threshold and the liquid supply temperature is greater than or equal to the first liquid supply temperature threshold;

[0088] The start control module is used to start the compressor in the refrigeration circuit.
