DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] The temperature control system is a system used to adjust the temperature of components, which can be specifically applied to power batteries. The temperature control system includes heat exchange pipes, which achieve temperature adjustment of power batteries and other components through heat exchange between the refrigerant, coolant and other heat exchange media in the heat exchange pipes and the power batteries.

[0026] In the related art, when a heat exchange pipe in a temperature control system fails, the ability of the heat exchange pipe to regulate the temperature of a component will drop sharply, thereby causing local overheating or overcooling of the component, causing the temperature-regulated component to be damaged due to the failure of the temperature control system.

[0027] Based on this, in order to solve the problem of how to avoid damage to the temperature-controlled components, the present application provides a control method, system, storage medium and vehicle for a temperature control system, wherein the temperature control system includes a first heat exchange pipe and a second heat exchange pipe. Among them, the first heat exchange pipe is used to heat or cool the target component, and can provide additional heat for the target component, or dissipate excess heat of the target component to the external environment; the second heat exchange pipe is configured to perform thermal balance on different areas of the target component. The temperature control system described in the present application is respectively provided with two different heat exchange pipes, one for heating or cooling the target component, and the other for making the heat distribution of the target component more balanced. The control method described in the present application adjusts the working states of the first heat exchange pipe and the second heat exchange pipe according to the current temperature difference of the target component, improves the heat distribution between different areas of the target component, and thereby avoids the occurrence of local overcooling or overheating of the target component, and prevents damage to the temperature-controlled components. The specific method is as follows: The first aspect of the present application proposes an embodiment, such as Figure 1 As shown in the step diagram of a control method of a temperature control system, the method is applied to the temperature control system of a vehicle, and is specifically applied to the controller of the temperature control system. The temperature control system is applied to a target component. Figure 2 A structural schematic diagram of a temperature control system is shown, and the temperature control system includes a first heat exchange pipe and a second heat exchange pipe, each of which is respectively attached to the target component. The first heat exchange pipe is used to heat or cool various areas of the target component in an operating state, and the second heat exchange pipe is used to perform thermal balance on various areas of the target component in an operating state. Specifically, the first heat exchange pipe and the second heat exchange pipe can achieve their respective functions by accommodating heat exchange media with different specific heat capacities. Among them, the specific heat capacity of the heat exchange medium in the first heat exchange pipe is lower than the specific heat capacity of the heat exchange medium in the second heat exchange pipe. Specifically, the heat exchange medium in the first heat exchange pipe can be a refrigerant, and the heat exchange medium in the second heat exchange pipe can be cooling water.

[0028] The first heat exchange pipe may be arranged at the center of the heat exchange plate, and the second heat exchange pipe surrounds the outer edge of the center.

[0029] In an optional embodiment, the target component may be a power battery, a drive motor or an engine of a vehicle. When the target component is a power battery, the first heat exchange pipe and the second heat exchange pipe may be integrated in a heat exchange plate, wherein the heat exchange plate may also be referred to as a direct cooling plate. The heat exchange plate includes a first plate surface and a second plate surface, the first plate surface and the second plate surface together form a receiving cavity, and the first heat exchange pipe and the second heat exchange pipe are evenly arranged in the receiving cavity. Furthermore, the first heat exchange pipe and the second heat exchange pipe are bonded to the power battery through the first plate surface or the second plate surface.

[0030] The main steps of the method described in this application include: Step S101, respectively obtaining the current working status of the first heat exchange pipeline and the second heat exchange pipeline.

[0031] The working state includes the running state or the shutdown state.

[0032] The working state of the first heat exchange pipeline includes an operating state or a shutdown state. In the operating state, the heat of the heat exchange medium in the pipeline of the first heat exchange pipeline is transferred to the target component, or the heat of the target component is absorbed by the heat exchange medium in the pipeline. In the shutdown state, since there is no heat exchange medium in the pipeline or the heat exchange medium does not flow, the impact of the first heat exchange pipeline on the temperature of the target component is much smaller than the impact when it is in the operating state.

[0033] The working state of the second heat exchange pipeline includes an operating state or a shutdown state. The heat exchange medium in the second heat exchange pipeline has a large specific heat capacity, so even if it absorbs or dissipates a lot of heat, it can keep its own temperature within a certain stable range. Therefore, in the operating state, it can achieve thermal balance of various parts of the target component, so that the temperature distribution of various areas of the target component is more balanced. In the shutdown state, since there is no heat exchange medium in the pipeline or the heat exchange medium does not flow, the impact on the temperature of the target component is much smaller than when it is in the operating state.

[0034] The current working state of the first heat exchange pipe and the second heat exchange pipe can be the working state of the first heat exchange pipe and the second heat exchange pipe automatically controlled by the vehicle based on operating parameters, or the working state of the first heat exchange pipe and the second heat exchange pipe controlled by the vehicle under the control of a control instruction triggered by a user.

[0035] Step S102, based on the current temperature difference between various areas of the target component and the current working states of the first heat exchange pipe and the second heat exchange pipe, the expected working states of the first heat exchange pipe and the second heat exchange pipe are determined.

[0036] The current working state of the first heat exchange pipe refers to the working state of the first heat exchange pipe at the current moment, which may be an operating state or a shutdown state. The expected working state of the first heat exchange pipe refers to the working state that the first heat exchange pipe hopes to be in, which may be an operating state or a shutdown state. It is worth noting that the current working state of the first heat exchange pipe and the expected working state may be the same state or different states. For example, when the current working state of the first heat exchange pipe is an operating state, the expected working state may be an operating state or a shutdown state.

[0037] The current working state of the second heat exchange pipe refers to the working state of the second heat exchange pipe at the current moment, which may be an operating state or a shutdown state. The expected working state of the second heat exchange pipe refers to the working state that the second heat exchange pipe hopes to be in, which may be an operating state or a shutdown state. It is worth noting that the current working state of the second heat exchange pipe and the expected working state may be the same state or different states. For example, when the current working state of the second heat exchange pipe is a shutdown state, the expected working state may be an operating state or a shutdown state.

[0038] The temperature difference refers to the temperature difference between the regions of the target component, and the current temperature difference refers to the temperature difference between the regions of the target component at the current moment. The current temperature difference characterizes the heat distribution state of each region of the target component, so by adjusting the current working states of the first heat exchange pipe and the second heat exchange pipe based on the current temperature difference, the desired working states of the first heat exchange pipe and the second heat exchange pipe can be adapted to the heat distribution state of each region of the target component, thereby realizing the redistribution of heat in each region of the target component.

[0039] Step S103, controlling the first heat exchange pipe and the second heat exchange pipe to be in their respective desired working states, so as to reduce the temperature difference between various areas of the target component.

[0040] The controller of the temperature control system is connected to the first heat exchange pipe and the second heat exchange pipe respectively. After determining the desired working state of the first heat exchange pipe and the second heat exchange pipe respectively, the controller sends control signals corresponding to the desired working state to the first heat exchange pipe and the second heat exchange pipe respectively, thereby controlling the first heat exchange pipe and the second heat exchange pipe to be in the desired working state respectively.

[0041] The temperature control system described in this embodiment includes a first heat exchange pipe and a second heat exchange pipe. Among them, the first heat exchange pipe is used to heat or cool the target component, and can provide additional heat for the target component, or dissipate the excess heat of the target component to the external environment; the second heat exchange pipe is configured to perform thermal balance on different areas of the target component. The temperature control system described in this embodiment is respectively provided with two different heat exchange pipes, one for heating or cooling the target component, and the other for making the heat distribution of the target component more balanced. The control method described in this application adjusts the working state of the first heat exchange pipe and the second heat exchange pipe according to the current temperature difference of the target component, improves the heat distribution between different areas of the target component, thereby avoiding the occurrence of local overcooling or overheating of the target component, and preventing damage to the temperature-controlled component.

[0042] Optionally, refer to Figure 3A method step diagram for determining an expected working state is shown, in step S102, based on the current temperature difference between the various regions of the target component and the current working state of the first heat exchange pipe and the second heat exchange pipe, the expected working state of each of the first heat exchange pipe and the second heat exchange pipe is determined, and the method further includes: Step S11: determining a target threshold based on the current working status of the first heat exchange pipe and the second heat exchange pipe.

[0043] The target threshold includes a first threshold and / or a second threshold, and the second threshold is greater than the first threshold.

[0044] Step S12: determining the desired working states of the first heat exchange pipe and the second heat exchange pipe based on the magnitude relationship between the current temperature difference and the target threshold.

[0045] The current working states of the first heat exchange pipeline and the second heat exchange pipeline respectively represent different reasons for the increase in temperature difference. For example, if the current working state of the first heat exchange pipeline is the running state, it indicates that the increase in temperature difference may be caused by the uneven heat provided by the first heat exchange pipeline; if the current working state of the first heat exchange pipeline is the shutdown state, it indicates that the increase in temperature difference may be caused by excessive heat generation in a certain area of ​​the target component.

[0046] Therefore, the target threshold can be determined based on the current working status of the first heat exchange pipe and the second heat exchange pipe, and the current working status of the first heat exchange pipe and the second heat exchange pipe can be adjusted based on the size relationship between the target threshold and the current temperature difference.

[0047] In an optional implementation, the first threshold may be 8°C, and the second threshold may be 10°C.

[0048] This embodiment infers the reasons for the increase in temperature difference between various areas of the target component based on the current working states of the first heat exchange pipe and the second heat exchange pipe, and then determines different thresholds for different reasons, so as to make targeted adjustments to the current working states of the first heat exchange pipe and the second heat exchange pipe, so that the expected working state is more in line with the working conditions of the temperature control system and the target component, thereby improving the efficiency of temperature regulation of the target component.

[0049] Optionally, determining the target threshold value based on the current working status of the first heat exchange pipe and the second heat exchange pipe in step S11 specifically includes the following steps: When the current working state of the first heat exchange pipe and / or the second heat exchange pipe is the operating state, the target threshold is determined to be the first threshold and the second threshold.

[0050] When the current working states of the first heat exchange pipe and the second heat exchange pipe are both the shutdown states, the target threshold is determined to be the second threshold.

[0051] When the first heat exchange pipe, or the second heat exchange pipe, or the first heat exchange pipe and the second heat exchange pipe are currently in operation, it indicates that the increase in temperature difference may be caused by the first heat exchange pipe or the second heat exchange pipe. Therefore, the target threshold value can be determined as the first threshold value and the second threshold value, so that the current working state of the first heat exchange pipe and the second heat exchange pipe is adjusted through the magnitude relationship between the temperature difference and the first threshold value and the second threshold value, respectively, to prevent the first heat exchange pipe or the second heat exchange pipe from further increasing the temperature difference.

[0052] When the current working states of the first heat exchange pipe and the second heat exchange pipe are both in the shutdown state, it indicates that the increase in temperature difference is not caused by the first heat exchange pipe and the second heat exchange pipe, but may be caused by the uneven heat generation of the target component itself. Therefore, the target threshold can be determined to be the second threshold, so that the current working states of the first heat exchange pipe and the second heat exchange pipe are adjusted according to the size relationship between the temperature difference and the second threshold, so as to prevent the target component from being damaged due to the uneven heat generation itself.

[0053] This embodiment determines the reason for the increase in temperature difference of the target component through the current working status of the first heat exchange pipe and the second heat exchange pipe, so that the adjustment of the working status of the first heat exchange pipe and the second heat exchange pipe is adapted to the reason for the increase in temperature difference, thereby improving the accuracy of the working status adjustment.

[0054] Optionally, after determining that the target threshold is the first threshold and the second threshold, determining the desired working states of the first heat exchange pipe and the second heat exchange pipe based on the magnitude relationship between the current temperature difference and the target threshold in step S12 specifically includes the following three situations: In case one, when the current temperature difference is less than the first threshold value, it is determined that the expected working state of the first heat exchange pipeline is the running state, and the expected working state of the second heat exchange pipeline is the shutdown state.

[0055] In case two, when the current temperature difference is greater than or equal to the first threshold value and less than the second threshold value, it is determined that the expected working states of the first heat exchange pipe and the second heat exchange pipe are both the operating states.

[0056] Case three, when the current temperature difference is greater than or equal to the second threshold, it is determined that the expected working state of the first heat exchange pipeline is the shutdown state, and the expected working state of the second heat exchange pipeline is the running state.

[0057] When the current temperature difference is less than the first threshold value, it indicates that the temperature difference between the various areas of the target component is small. At this time, the desired working state of the first heat exchange pipeline can be determined as the operating state, so that the first heat exchange pipeline heats or cools the target component, and the desired working state of the second heat exchange pipeline can be determined as the shutdown state, so that the second heat exchange pipeline no longer consumes energy.

[0058] When the current temperature difference is greater than or equal to the first threshold and less than the second threshold, it indicates that there is a need for uniform temperature of the target component. Therefore, the expected working states of the first heat exchange pipe and the second heat exchange pipe can be determined as the operating state, thereby achieving uniform temperature of the target component.

[0059] When the current temperature difference is greater than or equal to the second threshold, it indicates that the target component has a need for temperature equalization, but this need is too large, which may be caused by the heat exchange medium with a small specific heat capacity in the first heat exchange pipeline. Therefore, the expected working state of the first heat exchange pipeline should be determined as the shutdown state to prevent the first heat exchange pipeline from further increasing the temperature difference, and the expected working state of the second heat exchange pipeline should be determined as the running state, so as to perform thermal equalization on the target component through the second heat exchange pipeline.

[0060] This embodiment identifies whether there is a need for uniform temperature of the target component and the reason for the need for uniform temperature through the relationship between the temperature difference and the first threshold and the second threshold, and further adjusts the working status of the first heat exchange pipe and the second heat exchange pipe, thereby ensuring that the temperature difference can be effectively reduced after the working status is adjusted, thereby improving the working efficiency of the temperature control system.

[0061] Optionally, after determining that the target threshold is the second threshold, determining the desired working states of the first heat exchange pipe and the second heat exchange pipe based on the magnitude relationship between the current temperature difference and the target threshold in step S12 specifically includes the following situations: In case four, when the current temperature difference is less than the second threshold value, it is determined that the expected working states of the first heat exchange pipe and the second heat exchange pipe are both the shutdown states.

[0062] Case five, when the current temperature difference is greater than or equal to the second threshold, it is determined that the expected working state of the first heat exchange pipeline is the shutdown state, and the expected working state of the second heat exchange pipeline is the running state.

[0063] When the temperature difference is less than the second threshold, it indicates that there is no temperature equalization requirement for the target component, so the desired working state of the first heat exchange pipeline and the second heat exchange pipeline can be directly determined as the shutdown state, thereby reducing the energy consumption of the temperature control system.

[0064] When the temperature difference is greater than or equal to the second threshold, it indicates that there is a need for temperature equalization for the target component. Therefore, the desired working state of the first heat exchange pipeline can be determined as a shutdown state, and the desired working state of the second heat exchange pipeline can be determined as an operating state, thereby avoiding increasing the temperature difference in the first heat exchange pipeline while equalizing the temperature of the target component through the second heat exchange pipeline.

[0065] This embodiment adjusts the current working states of the first heat exchange pipe and the second heat exchange pipe through the relationship between the temperature difference and the second threshold value. When the target component has a temperature equalization requirement, the target component can be timely temperature-equalized and the reduction of the temperature equalization effect of the first heat exchange pipe on the second heat exchange pipe can be avoided, thereby improving the working efficiency of the temperature control system.

[0066] Optionally, there are at least two first heat exchange pipes, and at least two first heat exchange pipes are arranged along the first direction of the target component, and specifically can be symmetrically distributed. The inlet of the first heat exchange pipe is connected to at least two medium delivery pipes, and at least two of the medium delivery pipes are connected to the inlet through respective stop valves. The medium delivery pipe is used to deliver heat exchange medium to the first heat exchange pipe, and the temperature of the heat exchange medium delivered by at least two of the medium delivery pipes is different. Figure 4 Another method step diagram for determining an expected working state is shown, in which step S102 determines the expected working state of each of the first heat exchange pipe and the second heat exchange pipe based on the current temperature difference between the various regions of the target component and the current working state of each of the first heat exchange pipe and the second heat exchange pipe, specifically including the following steps: Step S21, obtaining a first temperature difference between a plurality of first regions of the target component.

[0067] The plurality of first regions are respectively arranged along a second direction intersecting with the first direction.

[0068] Step S22: determining the type of fault of the first heat exchange pipe based on the first temperature difference and the current working states of the first heat exchange pipe and the second heat exchange pipe.

[0069] The types of the faults include damage to any of the stop valves, or insufficient heat exchange medium in the first heat exchange pipeline.

[0070] Step S23: determining the expected working states of the first heat exchange pipe and the second heat exchange pipe based on the type of the fault.

[0071] refer to Figure 2 , Figure 2The two medium delivery pipelines shown in the figure include medium delivery pipeline A and medium delivery pipeline B. The medium delivery pipeline A delivers a heat exchange medium with a temperature lower than that of the target component, so that the first heat exchange pipeline can cool the target component. The medium delivery pipeline B delivers a heat exchange medium with a temperature higher than that of the target component, so that the first heat exchange pipeline can heat the target component.

[0072] refer to Figure 5 A distribution diagram of a first area is shown, Figure 5 The first heat exchange pipe A and the first heat exchange pipe B are included. The medium transport pipe is connected to the first heat exchange pipe A through the inlet 1, and the medium transport pipe is connected to the first heat exchange pipe B through the inlet 2. The medium transport pipe can be a refrigerant pipe of an air conditioner. The first direction and the second direction of the target component are as follows: Figure 5 As shown, the plurality of first regions may respectively include region A, region B, and region C. In an optional embodiment, the first direction and the second direction may be orthogonal, and the first heat exchange pipe A and the second heat exchange pipe B may be symmetrically distributed on both sides of the target component.

[0073] When the first temperature difference between area A, area B and area C is greater than the second threshold value, and the current working states of the first heat exchange pipe and the second heat exchange pipe are both in the shutdown state, it indicates that the target component has a large temperature difference, and the stop valve should be in a closed state. Since the stop valve should be in a closed state, but the target component has a large temperature difference, it can be inferred that the stop valve has leaked, and the heat exchange medium in the medium delivery pipeline has flowed into the first heat exchange pipe, resulting in a large temperature difference in various areas of the target component. Therefore, it can be determined that the type of fault is that any stop valve is damaged, and it can be further determined that the expected working state of the first heat exchange pipe is the shutdown state, and the expected working state of the second heat exchange pipe is the running state.

[0074] When the first temperature difference between area A, area B and area C is greater than the second threshold value, and the current working states of the first heat exchange pipe and the second heat exchange pipe are both in the running state, it indicates that a large temperature difference has occurred in the target component, and the stop valve is in the open state. Therefore, it can be inferred that it may be caused by insufficient heat exchange medium in the first heat exchange pipe, so the type of fault can be determined as insufficient heat exchange medium in the first heat exchange pipe, and it can be further determined that the expected working state of the first heat exchange pipe is the shutdown state, and the expected working state of the second heat exchange pipe is the running state.

[0075] In addition, if the temperature of the heat exchange medium in the two medium delivery pipelines is one greater than the temperature of the target component and the other less than the temperature of the target component, then if the fault type is that any stop valve is damaged, the damaged target stop valve can be further determined. Figure 2The medium delivery pipeline A shown in the figure has a delivery temperature lower than the heat exchange medium of the target component, and the medium delivery pipeline B has a delivery temperature higher than the heat exchange medium of the target component. If the first temperature difference is greater than the second threshold value, and the temperatures of the A region, the B region, and the C region increase in sequence, it can be determined that the stop valve of the medium delivery pipeline B is damaged; if the first temperature difference is greater than the second threshold value, and the temperatures of the A region, the B region, and the C region decrease in sequence, it can be determined that the stop valve of the medium delivery pipeline A is damaged.

[0076] This embodiment determines the type of fault of the first heat exchange pipe based on the first temperature difference and the current working states of the first heat exchange pipe and the second heat exchange pipe, and then determines the expected working states of the first heat exchange pipe and the second heat exchange pipe according to different fault types, and makes targeted adjustments to the working states of the first heat exchange pipe and the second heat exchange pipe, thereby improving the control accuracy of the temperature control system.

[0077] Optionally, when the type of the fault is insufficient heat exchange medium in the first heat exchange pipe, the step S23 of determining the desired working states of the first heat exchange pipe and the second heat exchange pipe based on the type of the fault may be implemented in the following manners: Acquire a second temperature difference between a plurality of second regions of the target component, wherein the plurality of second regions are respectively arranged along the first direction; Based on the second temperature difference, determining a location where the fault occurs; Based on the location where the fault occurs and the type of the fault, the expected working states of the first heat exchange pipe and the second heat exchange pipe are determined.

[0078] refer to Figure 6 A schematic diagram of the distribution of the second area is shown, Figure 6 The heat exchange device includes two first heat exchange pipes, namely, a first heat exchange pipe A and a first heat exchange pipe B. The medium transport pipe is connected to the first heat exchange pipe A through an inlet 1, and the medium transport pipe is connected to the first heat exchange pipe B through an inlet 2. The plurality of second regions may include a D region, an E region, and an F region, respectively. The temperature of the D region is adjusted by the first heat exchange pipe A, the temperature of the E region is adjusted by the first heat exchange pipe A and the first heat exchange pipe B, and the temperature of the F region is adjusted by the first heat exchange pipe B.

[0079] When the first heat exchange pipe operates normally, the heat dissipated or absorbed by the first heat exchange pipe A and the first heat exchange pipe B are the same, so the temperatures of the three regions D, E and F should be the same. However, when there is a part with insufficient heat exchange medium in the first heat exchange pipe A or the first heat exchange pipe B, the temperatures of the three regions D, E and F will be different, so the area with insufficient heat exchange medium can be located by the difference in temperature between the three regions D, E and F (i.e., the second temperature difference).

[0080] Specifically, when the temperature of the heat exchange medium flowing out of the medium delivery pipeline is higher than the temperature of the target component, that is, the first heat exchange pipeline A and the first heat exchange pipeline B are heating the target component, if the second temperature difference is greater than the second threshold value, and the temperatures of the D area, the E area, and the F area are indicated to decrease successively, it can be determined that the area with insufficient heat exchange medium is the first heat exchange pipeline corresponding to the F area; otherwise, it can be determined that the area with insufficient heat exchange medium is the first heat exchange pipeline corresponding to the D area.

[0081] When the temperature of the heat exchange medium flowing out of the medium delivery pipeline is the temperature of the first target component, that is, the first heat exchange pipeline A and the first heat exchange pipeline B are dissipating heat to the target component, if the second temperature difference is greater than the second threshold value, and the temperatures of the D area, the E area, and the F area are indicated to decrease in sequence, it can be determined that the area with insufficient heat exchange medium is the first heat exchange pipeline corresponding to the D area; otherwise, it can be determined that the area with insufficient heat exchange medium is the first heat exchange pipeline corresponding to the F area.

[0082] In this embodiment, when the fault type is insufficient heat exchange medium in the first heat exchange pipe, the second temperature difference in the second area is further used to locate the location of the fault, and then the working conditions of the first heat exchange pipe and the second heat exchange pipe are further adjusted in a targeted manner according to the type of fault and the location of the fault, thereby further improving the accuracy of the temperature control system control.

[0083] Based on the above embodiments, reference Figure 7 A flow chart of a control method of a temperature control system is shown, and the control method of the temperature control system described in this application will be exemplarily described below: The control method of the temperature control system described in the present application is applied to the temperature control system of the vehicle, and is specifically applied to the controller of the temperature control system. The temperature control system is applied to the target component. The temperature control system includes a second heat exchange pipe respectively fitted with the target component, at least two first heat exchange pipes and at least two medium delivery pipes. The at least two medium delivery pipes are respectively connected to the inlet of the first heat exchange pipe through their own stop valves. The first heat exchange pipe is used to heat or cool various areas of the target component in the operating state, and the second heat exchange pipe is used to perform thermal balance on different areas of the target component in the operating state.

[0084] The control method specifically includes the following steps: First, the current working status of the first heat exchange pipeline and the second heat exchange pipeline is obtained respectively, wherein the working status includes an operating status or a shutdown status.

[0085] Afterwards, based on the current working states of the first heat exchange pipe and the second heat exchange pipe, a target threshold corresponding to the current temperature difference is determined. Specifically, when at least one of the first heat exchange pipe and the second heat exchange pipe is currently in operation, the target threshold is determined to be the first threshold and the second threshold. When the current working states of the first heat exchange pipe and the second heat exchange pipe are both in the shutdown state, the target threshold is determined to be the second threshold.

[0086] When the target thresholds are the first threshold and the second threshold, if the current temperature difference is less than the first threshold, the expected working state of the first heat exchange pipe is determined as the running state, and the expected working state of the second heat exchange pipe is determined as the shutdown state; if the current temperature difference is greater than or equal to the first threshold and less than the second threshold, the expected working states of the first heat exchange pipe and the second heat exchange pipe are both determined as the running state; if the current temperature difference is greater than or equal to the second threshold, the expected working state of the first heat exchange pipe is determined as the shutdown state, and the expected working state of the second heat exchange pipe is determined as the running state.

[0087] When the target threshold is the second threshold, if the current temperature difference is less than the second threshold, the expected working state of the first heat exchange pipe and the second heat exchange pipe is determined to be a shutdown state; if the current temperature difference is greater than or equal to the second threshold, the expected working state of the first heat exchange pipe is determined to be a shutdown state, and the expected working state of the second heat exchange pipe is determined to be an operating state.

[0088] After determining the desired working states of the first heat exchange pipeline and the second heat exchange pipeline, the first heat exchange pipeline and the second heat exchange pipeline are controlled to be in their corresponding adjusted operating states.

[0089] In addition, while obtaining the current working states of the first heat exchange pipe and the second heat exchange pipe, the first temperature difference between the multiple first regions and the second temperature difference between the multiple second regions of the target component can also be obtained, wherein the multiple first regions are arranged along a second direction intersecting the first direction, and the multiple second regions are arranged along the first direction.

[0090] Afterwards, based on the first temperature difference, the current working states of the first heat exchange pipe and the second heat exchange pipe, the type of fault of the first heat exchange pipe is determined, and based on the type of fault, the expected working states of the first heat exchange pipe and the second heat exchange pipe are determined.

[0091] When the type of fault is insufficient heat exchange medium in the first heat exchange pipe, the location of the fault can be determined based on the second temperature difference, and the expected working states of the first heat exchange pipe and the second heat exchange pipe can be determined based on the location of the fault and the type of the fault.

[0092] After determining the desired working states of the first heat exchange pipeline and the second heat exchange pipeline, the first heat exchange pipeline and the second heat exchange pipeline are controlled to be in their corresponding adjusted operating states.

[0093] Based on the above embodiments, this embodiment is based on Figure 2 , Figure 5 as well as Figure 6 For example, an example based on an actual application scenario is given. The first threshold is 8°C, the second threshold is 10°C, Figure 2 The medium delivery pipeline A delivers a heat exchange medium with a temperature lower than that of the target component, so that the first heat exchange pipeline can cool the target component; the medium delivery pipeline B delivers a heat exchange medium with a temperature higher than that of the target component, so that the first heat exchange pipeline can heat the target component.

When the current working states of the first heat exchange pipe (it is worth noting that the first heat exchange pipe described here and in the following of this embodiment includes the first heat exchange pipe A and the first heat exchange pipe B) and the second heat exchange pipe are both in the shutdown state, if the first temperature difference is less than 10°C, it is determined that the expected working states of the first heat exchange pipe and the second heat exchange pipe are both in the shutdown state; if the first temperature difference is greater than or equal to 10°C, and indicates that the temperature of area A and area B is greater than that of area C, it can be determined that the stop valve of the medium conveying pipe A is damaged, and at this time it can be determined that the expected working state of the first heat exchange pipe is the shutdown state, and the expected working state of the second heat exchange pipe is the running state. If the first temperature difference is greater than or equal to 10°C, and indicates that the temperature of area A and area B is less than or equal to that of area C, it can be determined that the stop valve of the medium conveying pipe B is damaged, and at this time it can be determined that the expected working state of the first heat exchange pipe is the shutdown state, and the expected working state of the second heat exchange pipe is the running state.

[0095] In the case where the current working state of any one of the first heat exchange pipe and the second heat exchange pipe is the running state, if the first temperature difference is less than 8°C, it is determined that the expected working state of the first heat exchange pipe is the running state, and the expected working state of the second heat exchange pipe is the shutdown state; if the first temperature difference is greater than or equal to 8°C and less than 10°C, it is determined that the expected working states of the first heat exchange pipe and the second heat exchange pipe are both the running state; if the first temperature difference is greater than or equal to 10°C, it can be determined that the heat exchange medium in the first heat exchange pipe is insufficient, and it can be further determined that the expected working state of the first heat exchange pipe is the shutdown state, and the expected working state of the second heat exchange pipe is the running state. In addition, in the case where the current working state of any one of the first heat exchange pipe and the second heat exchange pipe is the running state, if the first temperature difference is greater than or equal to 10°C, and the first temperature difference indicates that the temperature of area A and area B is higher than the temperature of area C, it can also be determined that the heat exchange medium transported by the medium transport pipe B is insufficient; if the first temperature difference is greater than or equal to 10°C, and the first temperature difference indicates that the temperature of area C is greater than the temperature of area A and the temperature of area B, it can also be determined that the heat exchange medium transported by the medium transport pipe A is insufficient.

When the current working state of any one of the first heat exchange pipe and the second heat exchange pipe is the running state, and the heat exchange medium in the first heat exchange pipe is transported by the medium transport pipe B, if the second temperature difference is less than 8°C, it is determined that the expected working state of the first heat exchange pipe is the running state, and the expected working state of the second heat exchange pipe is the shutdown state; if the second temperature difference is greater than or equal to 8°C and less than 10°C, it is determined that the expected working states of the first heat exchange pipe and the second heat exchange pipe are both the running state; if the second temperature difference is greater than or equal to 10°C, and the temperatures of the D area, the E area, and the F area decrease in sequence, it can be determined that the area with insufficient heat exchange medium is the first heat exchange pipe corresponding to the F area; if the second temperature difference is greater than or equal to 10°C, and the temperatures of the D area, the E area, and the F area increase in sequence, it can be determined that the area with insufficient heat exchange medium is the first heat exchange pipe corresponding to the D area. After that, it is further determined that the expected working state of the first heat exchange pipe is the shutdown state, and the expected working state of the second heat exchange pipe is the running state.
