[0001] The present application relates to the field of vehicle technology, and more specifically, to a control method, system, storage medium, and vehicle for a temperature control system. Background Art

[0002] A thermostat is a system used to regulate component temperature, specifically power batteries. It includes heat exchange piping, which regulates the temperature of components such as power batteries by exchanging heat with the refrigerant, coolant, or other heat transfer medium in the piping.

Summary of the Invention

[0004] Based on this, the present application provides a control method, system, storage medium and vehicle for a temperature control system to solve the problem of how to avoid damage to the temperature-controlled components.

[0005] According to a first aspect of an embodiment of the present application, a method for controlling a temperature control system is provided.

[0010] Determining a target threshold based on the current operating states of the first heat exchange pipe and the second heat exchange pipe; wherein the target threshold includes a first threshold and / or a second threshold, and the second threshold is greater than the first threshold;

[0011] Based on the magnitude relationship between the current temperature difference and the target threshold, the desired operating states of the first heat exchange pipe and the second heat exchange pipe are determined.

[0012] This embodiment infers the reasons for the increase in temperature difference between different areas of the target component based on the current working status of the first heat exchange pipe and the second heat exchange pipe, and then determines different thresholds for different reasons to make targeted adjustments to the current working status of the first heat exchange pipe and the second heat exchange pipe, so that the desired working status 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.

[0025] This embodiment adjusts the current working status 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.

[0029] Based on the type of the fault, desired working states of the first heat exchange pipe and the second heat exchange pipe are determined.

[0030] This embodiment determines the type of fault in the first heat exchange pipe based on the first temperature difference and the current operating states of the first and second heat exchange pipes.

[0052] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0053] A thermostat is a system used to regulate component temperature, specifically power batteries. It includes heat exchange piping, which regulates the temperature of components such as power batteries by exchanging heat with the refrigerant, coolant, or other heat transfer medium in the piping.

[0054] 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, causing the component to be locally overheated or overcooled, causing the temperature-controlled component to be damaged due to the failure of the temperature control system.

[0055] 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 status 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:

[0056] The first aspect of this application proposes an embodiment, such as Figure 1 As shown in the figure, a control method of a temperature control system 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 in contact with 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. 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.

[0057] 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.

[0058] In an optional embodiment, the target component may be a vehicle's power battery, drive motor, or engine, etc. When the target component is a power battery, the first heat exchange pipe and the second heat exchange pipe may be integrated into a heat exchange plate, which may also be referred to as a direct cooling plate. The heat exchange plate includes a first plate surface and a second plate surface, which together form a receiving cavity, and the first heat exchange pipe and the second heat exchange pipe are evenly arranged within 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.

[0059] The main steps of the method described in this application include:

[0060] Step S101: obtaining the current working status of the first heat exchange pipe and the second heat exchange pipe respectively.

[0061] The working state includes the running state or the shutdown state.

[0062] The operating state of the first heat exchange pipeline includes an operating state and a shutdown state. In the operating state, the heat of the heat exchange medium in 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, the first heat exchange pipeline has a much smaller impact on the temperature of the target component than when it is in the operating state, because the heat exchange medium is not present in the pipeline or is not flowing.

[0063] The second heat exchange pipeline operates in either an operating state or a shutdown state. Due to its large specific heat capacity, the heat exchange medium in the second heat exchange pipeline can maintain its temperature within a stable range even when absorbing or dissipating a large amount of heat. Therefore, in the operating state, thermal equilibrium can be achieved across the target component, resulting in a more balanced temperature distribution across the target component. In the shutdown state, the second heat exchange pipeline has a much smaller impact on the target component's temperature than when in the operating state, as the heat exchange medium is absent or non-flowing within the pipeline.

[0064] The current working status of the first heat exchange pipe and the second heat exchange pipe can be the working status of the first heat exchange pipe and the second heat exchange pipe automatically controlled by the vehicle based on operating parameters, or the working status 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 the user.

[0065] Step S102 : determining the desired working states 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 states of the first heat exchange pipe and the second heat exchange pipe.

[0066] The current operating state of the first heat exchange pipeline refers to the operating state of the first heat exchange pipeline at the current moment, which can be an operating state or a shutdown state. The desired operating state of the first heat exchange pipeline refers to the operating state that the first heat exchange pipeline is expected to be in, which can be an operating state or a shutdown state. It is worth noting that the current operating state and the desired operating state of the first heat exchange pipeline can be the same state or different states. For example, when the current operating state of the first heat exchange pipeline is an operating state, the desired operating state can be an operating state or a shutdown state.

[0067] The current operating state of the second heat exchange pipe refers to the operating state of the second heat exchange pipe at the current moment, which can be an operating state or a shutdown state. The desired operating state of the second heat exchange pipe refers to the operating state that the second heat exchange pipe is expected to be in, which can be an operating state or a shutdown state. It is worth noting that the current operating state and the desired operating state of the second heat exchange pipe can be the same state or different states. For example, when the current operating state of the second heat exchange pipe is a shutdown state, the desired operating state can be an operating state or a shutdown state.

[0068] The temperature difference refers to the temperature difference between different regions of the target component. The current temperature difference refers to the temperature difference between different regions of the target component at the current moment. The current temperature difference represents the heat distribution state of each region of the target component. Therefore, by adjusting the current operating states of the first and second heat exchange pipes based on the current temperature difference, the desired operating states of the first and second heat exchange pipes can be adapted to the heat distribution state of each region of the target component, thereby redistributing heat among the regions of the target component.

[0069] 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.

[0070] The controller of the temperature control system is connected to the first heat exchange pipe and the second heat exchange pipe. After determining the desired operating state of each of the first heat exchange pipe and the second heat exchange pipe, the controller sends control signals corresponding to the respective desired operating states to the first heat exchange pipe and the second heat exchange pipe, thereby controlling the first heat exchange pipe and the second heat exchange pipe to maintain the desired operating state.

[0071] 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 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 status 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 component.

[0072] Optionally, refer to Figure 3 A step diagram of a method for determining a desired operating state is shown. In step S102, based on the current temperature difference between the various regions of the target component and the current operating states of the first heat exchange pipe and the second heat exchange pipe, the desired operating states of the first heat exchange pipe and the second heat exchange pipe are determined. The method further includes:

[0073] Step S11: determining a target threshold based on the current working status of each of the first heat exchange pipe and the second heat exchange pipe.

[0074] The target threshold includes a first threshold and / or a second threshold, and the second threshold is greater than the first threshold.

[0075] 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.

[0076] The current operating status of the first and second heat exchange pipes indicates different reasons for the increased temperature difference. For example, if the first heat exchange pipe is currently operating in the running state, the increased temperature difference may be caused by uneven heat supply from the first heat exchange pipe. If the first heat exchange pipe is currently operating in the shutdown state, the increased temperature difference may be caused by excessive heat generation in a certain area of ​​the target component.

[0077] 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.

[0078] In an optional embodiment, the first threshold value may be 8°C, and the second threshold value may be 10°C.

[0079] This embodiment infers the reasons for the increase in temperature difference between different areas of the target component based on the current working status of the first heat exchange pipe and the second heat exchange pipe, and then determines different thresholds for different reasons to make targeted adjustments to the current working status of the first heat exchange pipe and the second heat exchange pipe, so that the desired working status 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.

[0080] Optionally, determining the target threshold 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:

[0081] 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.

[0082] 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.

[0083] If the first heat exchange pipe, the second heat exchange pipe, or both 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 thresholds can be determined as the first threshold and the second threshold. Based on the relationship between the temperature difference and the first threshold and the second threshold, the current operating state of the first heat exchange pipe and the second heat exchange pipe can be adjusted to prevent the first heat exchange pipe or the second heat exchange pipe from causing the temperature difference to increase further.

[0084] If both the first and second heat exchange pipes are currently operating in the shutdown state, this indicates that the increased temperature difference is not caused by the first and second heat exchange pipes, but rather by uneven heat generation within the target component itself. Therefore, the target threshold can be determined to be the second threshold. Based on the relationship between the temperature difference and the second threshold, the current operating states of the first and second heat exchange pipes can be adjusted to prevent damage to the target component due to uneven heat generation.

[0085] This embodiment determines the cause of the increase in the 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 cause of the increase in the temperature difference, thereby improving the accuracy of the working status adjustment.

[0086] Optionally, after determining that the target threshold is the first threshold and the second threshold, determining the desired operating 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:

[0087] Case 1: When the current temperature difference is less than the first threshold, 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.

[0088] Case 2: When the current temperature difference is greater than or equal to the first threshold and less than the second threshold, 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.

[0089] 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 pipe is the shutdown state, and the expected working state of the second heat exchange pipe is the running state.

[0090] When the current temperature difference is less than the first threshold, 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 to be the running 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 to be the shutdown state, so that the second heat exchange pipeline no longer consumes energy.

[0091] 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 temperature uniformity 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 temperature uniformity of the target component.

[0092] If the current temperature difference is greater than or equal to the second threshold, it indicates that the target component requires temperature equalization, but this requirement is excessive, presumably due to the low specific heat capacity of the heat exchange medium in the first heat exchange pipe. Therefore, the first heat exchange pipe should be set to a shutdown state to prevent it from further increasing the temperature difference. At the same time, the second heat exchange pipe should be set to an operating state to achieve thermal equalization of the target component through the second heat exchange pipe.

[0093] This embodiment identifies whether there is a need for uniform temperature for 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 to ensure that the temperature difference can be effectively reduced after the working status is adjusted, thereby improving the working efficiency of the temperature control system.

[0094] Optionally, after determining that the target threshold is the second threshold, determining the desired operating 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:

[0095] Case 4: When the current temperature difference is less than the second threshold, it is determined that the expected working states of the first heat exchange pipe and the second heat exchange pipe are both the shutdown state.

[0096] 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 pipe is the shutdown state, and the expected working state of the second heat exchange pipe is the running state.

[0097] When the temperature difference is less than the second threshold, it indicates that there is no temperature equalization requirement for the target component. Therefore, the desired working state of the first heat exchange pipe and the second heat exchange pipe can be directly determined as the shutdown state, thereby reducing the energy consumption of the temperature control system.

[0098] When the temperature difference is greater than or equal to the second threshold, it indicates that there is a need for temperature equalization of the target component. Therefore, the expected working state of the first heat exchange pipeline can be determined as the shutdown state, and the expected working state of the second heat exchange pipeline can be determined as the running state, so as to avoid increasing the temperature difference of the first heat exchange pipeline while equalizing the temperature of the target component through the second heat exchange pipeline.

[0099] This embodiment adjusts the current working status 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.

[0100] Optionally, there are at least two first heat exchange pipes, and the 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 for determining a desired operating state is shown in the step diagram. Step S102 determines the desired operating 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 operating state of each of the first heat exchange pipe and the second heat exchange pipe. The method specifically includes the following steps:

[0101] Step S21: obtaining a first temperature difference between a plurality of first regions of the target component.

[0102] The plurality of first regions are respectively arranged along a second direction intersecting with the first direction.

[0103] 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.

[0104] The type of the fault includes damage to any of the stop valves or insufficient heat exchange medium in the first heat exchange pipe.

[0105] Step S23: Determine the desired working states of the first heat exchange pipe and the second heat exchange pipe based on the type of the fault.

[0106] refer to Figure 2 , Figure 2 The two medium delivery pipes shown in the figure include medium delivery pipe A and medium delivery pipe B. Medium delivery pipe A delivers a heat exchange medium with a lower temperature than the target component, allowing the first heat exchange pipe to cool the target component. Medium delivery pipe B delivers a heat exchange medium with a higher temperature than the target component, allowing the first heat exchange pipe to heat the target component.

[0107] refer to Figure 5 A schematic diagram of the distribution of the 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 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.

[0108] When the first temperature difference between regions A, B, and C is greater than the second threshold, and both the first and second heat exchange pipes are currently operating in the shutdown state, this indicates that the target component has experienced a large temperature difference and the shutoff valve should be in the closed state. Since the shutoff valve should be closed, but the target component has experienced a large temperature difference, it can be inferred that the shutoff valve is leaking, and the heat exchange medium in the medium delivery pipe has flowed into the first heat exchange pipe, resulting in a large temperature difference between the various regions of the target component. Therefore, the fault type can be determined to be damage to any of the shutoff valves, and further, it can be determined that the expected operating state of the first heat exchange pipe is the shutdown state, and the expected operating state of the second heat exchange pipe is the operating state.

[0109] When the first temperature difference between regions A, B, and C exceeds the second threshold, and both the first and second heat exchange pipes are currently operating, it indicates that a significant temperature difference has occurred in the target component and the shutoff valve is open. Therefore, it can be inferred that insufficient heat exchange medium in the first heat exchange pipe may be the cause of the fault. Therefore, the fault type can be determined to be insufficient heat exchange medium in the first heat exchange pipe. Furthermore, it can be determined that the expected operating state for the first heat exchange pipe is shutdown, while the expected operating state for the second heat exchange pipe is operating.

[0110] In addition, if the temperature of the heat exchange medium in the two medium delivery pipelines is higher than the temperature of the target component and lower 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 2 In the example shown, the temperature of the medium transport pipeline A is lower than that of the target component's heat exchange medium, while the temperature of the medium transport pipeline B is higher. If the first temperature difference is greater than the second threshold and indicates that the temperatures in regions A, B, and C increase in sequence, it can be determined that the shutoff valve in medium transport pipeline B is damaged. If the first temperature difference is greater than the second threshold and indicates that the temperatures in regions A, B, and C decrease in sequence, it can be determined that the shutoff valve in medium transport pipeline A is damaged.

[0111] This embodiment determines the type of fault in 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.

[0112] Optionally, when the fault type is insufficient heat exchange medium in the first heat exchange pipe, determining the desired working states of the first heat exchange pipe and the second heat exchange pipe based on the fault type in step S23 may be specifically implemented in the following manner:

[0113] obtaining 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;

[0114] determining a location where the fault occurs based on the second temperature difference;

[0115] Based on the location where the fault occurs and the type of the fault, desired working states of the first heat exchange pipe and the second heat exchange pipe are determined.

[0116] refer to Figure 6 A schematic diagram of the distribution of the second area is shown. Figure 6 The system includes two first heat exchange pipes, 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 via inlet 1, and the medium transport pipe is connected to the first heat exchange pipe B via inlet 2. The multiple second zones may include zone D, zone E, and zone F. The temperature of zone D is regulated by the first heat exchange pipe A, the temperature of zone E is regulated jointly by the first heat exchange pipe A and the first heat exchange pipe B, and the temperature of zone F is regulated by the first heat exchange pipe B.

[0117] When the first heat exchange pipe operates normally, the heat dissipated or absorbed by first heat exchange pipe A and first heat exchange pipe B is the same, so the temperatures in regions D, E, and F should be the same. However, when there is insufficient heat exchange medium in either first heat exchange pipe A or first heat exchange pipe B, the temperatures in regions D, E, and F will differ. Therefore, the temperature difference between regions D, E, and F (i.e., the second temperature difference) can be used to locate the region with insufficient heat exchange medium.

[0118] 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 decrease in sequence, 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.

[0119] 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 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.

[0120] 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.

[0121] Based on the above embodiment, reference Figure 7 A flow chart of a control method for a temperature control system is shown. The following is an exemplary description of the control method for the temperature control system described in this application:

[0122] The control method of the temperature control system described in this application is applicable to the temperature control system of a vehicle, and specifically to the controller of the temperature control system. The temperature control system is applied to a target component. The temperature control system includes a second heat exchange pipe respectively attached to 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 respective stop valves. 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 balancing on different areas of the target component in an operating state.

[0123] The control method specifically includes the following steps:

[0124] First, the current working status of the first heat exchange pipe and the second heat exchange pipe is obtained respectively, wherein the working status includes an operating state or a shutdown state.

[0125] Then, based on the current operating status of each of the first and second heat exchange pipes, a target threshold corresponding to the current temperature difference is determined. Specifically, if at least one of the first and second heat exchange pipes is currently in operation, the target thresholds are determined to be the first and second thresholds. If both the first and second heat exchange pipes are currently in the shutdown state, the target threshold is determined to be the second threshold.

[0126] 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 to be the running state, and the expected working state of the second heat exchange pipe is determined to be 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 to be 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 to be the shutdown state, and the expected working state of the second heat exchange pipe is determined to be the running state.

[0127] 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 the 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 the shutdown state, and the expected working state of the second heat exchange pipe is determined to be the running state.

[0128] After determining the desired operating states of the first heat exchange pipe and the second heat exchange pipe, the first heat exchange pipe and the second heat exchange pipe are controlled to be in their corresponding adjusted operating states.

[0129] In addition, while obtaining the current operating status of each of the first and second heat exchange pipes, a first temperature difference between a plurality of first regions and a second temperature difference between a plurality of second regions of the target component can also be obtained. The plurality of first regions are arranged along a second direction intersecting the first direction, and the plurality of second regions are arranged along the first direction.

[0130] Afterwards, based on the first temperature difference, the current working status 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 status of the first heat exchange pipe and the second heat exchange pipe is determined.

[0131] In the case where 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.

[0132] After determining the desired operating states of the first heat exchange pipe and the second heat exchange pipe, the first heat exchange pipe and the second heat exchange pipe are controlled to be in their corresponding adjusted operating states.

[0133] Based on the above embodiments, this embodiment uses Figure 2 、 Figure 5 as well as Figure 6For 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 pipe A delivers a heat exchange medium with a temperature lower than that of the target component, so the first heat exchange pipe can cool the target component; the medium delivery pipe B delivers a heat exchange medium with a temperature higher than that of the target component, so the first heat exchange pipe can heat the target component. Figure 2 The medium conveying pipeline A and medium conveying pipeline B in the Figure 5 as well as Figure 6 Inlet 1 and Inlet 2 connections are shown.

[0134] refer to Figure 5 First, obtain the first temperature difference between regions A, B, and C. If the first heat exchange pipe (note that the first heat exchange pipe described here and in this embodiment below includes the first heat exchange pipe A and the first heat exchange pipe B) and the second heat exchange pipe are both currently in the shutdown state, if the first temperature difference is less than 10°C, then the desired operating state of the first and second heat exchange pipes is determined to be the shutdown state. If the first temperature difference is greater than or equal to 10°C and indicates that the temperatures in regions A and B are greater than those in region C, then it can be determined that the shutoff valve of medium delivery pipe A is damaged. In this case, the desired operating state of the first heat exchange pipe can be determined to be the shutdown state, while the desired operating state of the second heat exchange pipe is the operating state. If the first temperature difference is greater than or equal to 10°C and indicates that the temperatures in regions A and B are less than or equal to those in region C, then it can be determined that the shutoff valve of medium delivery pipe B is damaged. In this case, the desired operating state of the first heat exchange pipe can be determined to be the shutdown state, while the desired operating state of the second heat exchange pipe is the operating state.

[0135] If the current operating state of either the first or second heat exchange pipe is running, and the first temperature difference is less than 8°C, the desired operating state of the first heat exchange pipe is determined to be running, and the desired operating state of the second heat exchange pipe is shutdown. If the first temperature difference is greater than or equal to 8°C and less than 10°C, the desired operating states of both the first and second heat exchange pipes are determined to be running. 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 desired operating state of the first heat exchange pipe is shutdown, and the desired operating state of the second heat exchange pipe is running. In addition, if the current operating state of either the first or second heat exchange pipe is running, if the first temperature difference is greater than or equal to 10°C, and the first temperature difference indicates that the temperature of region A and region B is higher than the temperature of region C, it can also be determined that the heat exchange medium transported by 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 region C is higher than the temperature of region A and region B, it can also be determined that the heat exchange medium transported by medium transport pipe A is insufficient.

[0136] refer to Figure 6 First, obtain the second temperature difference between regions D, E, and F. If either the first or second heat exchange pipe is currently operating in the running state, and the heat exchange medium in the first heat exchange pipe is transported by medium transport pipe B, if the second temperature difference is less than 8°C, the desired operating state of the first heat exchange pipe is determined to be running, and the desired operating state of the second heat exchange pipe is shutdown. If the second temperature difference is greater than or equal to 8°C and less than 10°C, the desired operating states of both the first and second heat exchange pipes are determined to be running. If the second temperature difference is greater than or equal to 10°C and indicates that the temperatures in regions D, E, and F decrease in sequence, the region with insufficient heat exchange medium can be determined to be the first heat exchange pipe corresponding to region F. If the second temperature difference is greater than or equal to 10°C and indicates that the temperatures in regions D, E, and F increase in sequence, the region with insufficient heat exchange medium can be determined to be the first heat exchange pipe corresponding to region D. Subsequently, the desired operating state of the first heat exchange pipe is further determined to be shutdown, and the desired operating state of the second heat exchange pipe is determined to be running.

[0137] If either the first or second heat exchange pipe is currently in the operating state and the heat exchange medium in the first heat exchange pipe is transported by medium transport pipe A, if the second temperature difference is less than 8°C, the desired operating state of the first heat exchange pipe is determined to be the operating state, and the desired operating 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, the desired operating states of both the first and second heat exchange pipes are determined to be the operating state. If the second temperature difference is greater than or equal to 10°C and indicates that the temperatures of regions D, E, and F decrease in sequence, the region with insufficient heat exchange medium can be determined to be the first heat exchange pipe corresponding to region D. If the second temperature difference is greater than or equal to 10°C and indicates that the temperatures of regions D, E, and F increase in sequence, the region with insufficient heat exchange medium can be determined to be the first heat exchange pipe corresponding to region F. Subsequently, the desired operating state of the first heat exchange pipe is further determined to be the shutdown state, and the desired operating state of the second heat exchange pipe is determined to be the operating state.
