Description

Technical Field

[0001] The present application relates to the field of intelligent control technology, and more specifically, to a method and system for controlling the temperature inside an automobile. Background Art

[0002] With the development of science and technology, the popularity rate of automobiles is getting higher and higher. However, automobiles with long service life and aging equipment have poor heat dissipation performance, and in some automobiles, the engine is extremely close to the driver's cab, which will cause the engine temperature to be conducted to the interior of the automobile faster. When the heat generated during the operation of the engine after startup cannot be dissipated in time, the accumulated heat causes the engine temperature to be too high, resulting in a rapid increase in the interior temperature of the automobile, making the driving environment uncomfortable. In this case, the driving experience of the vehicle driver is poor, and at the same time, the driver's attention cannot be concentrated, so the safety of the driver cannot be guaranteed.

[0003] The traditional engine cooling method is to directly force the coolant to circulate to cool the engine. Although this cooling method is simple and effective, with the use of the water tank for placing the coolant, the scale in the tank accumulates, which easily leads to insufficient heat dissipation performance, and this cooling method lacks a buffer stage in the heat transfer process of the engine.

[0004] Therefore, generally speaking, there is a lack of a technical solution that can improve the intelligence of automobile interior temperature control while ensuring driving safety. Summary of the Invention

[0005] In order to solve the above technical problems, the present application is proposed. The embodiments of the present application provide a method and system for controlling the temperature inside an automobile, and its main purpose is to provide a technical solution that can improve the intelligence of automobile interior temperature control while ensuring driving safety.

The engine heat dissipation device includes a heat collection pipeline, a heat collection inner shell, a radiation coating, a heat collection outer shell, a heat dissipation structure and a refrigeration structure. The heat collection pipeline is uniformly distributed on the inner wall surface of the heat collection inner shell, the outer wall surface of the heat collection inner shell is a radiation coating, the heat collection outer shell surrounds the heat collection inner shell, and the space between the heat collection outer shell and the heat collection inner shell is in a vacuum state;

[0008] Using the heat collection pipeline to collect the heat generated by the engine, and after successfully collecting, transferring the heat to the heat collection inner shell, and then radiating the heat to the heat collection outer shell through the radiation coating;

[0009] Measure the temperature of the outer wall surface of the heat - collecting housing, and use the heat - insulating material pre - wrapped on the outer wall surface of the heat - collecting housing to dissipate the heat to the external environment of the vehicle, where the thickness of the heat - insulating material can be adaptively adjusted according to the temperature of the outer wall surface;

[0010] According to the temperature of the outer wall surface, perform temperature regulation on the engine through the refrigeration structure;

[0011] When the temperature of the engine meets the preset temperature threshold, start the fiber optic temperature sensor, where the fiber optic temperature sensor is connected to the vehicle - mounted air conditioner. The fiber optic temperature sensor can control the opening state of the vehicle - mounted air conditioner, and measure the actual value of the interior temperature of the vehicle using the fiber optic temperature sensor;

[0012] Adjust the working state of the vehicle - mounted air conditioner according to the actual value of the interior temperature of the vehicle to complete the control of the interior temperature of the vehicle.

[0013] According to another aspect of the present application, a control system for the interior temperature of a vehicle is provided, which includes:

[0014] A heat - dissipation device startup module, which is used to receive the vehicle interior temperature control instruction and start the engine heat - dissipation device according to the vehicle interior temperature control instruction. The engine heat - dissipation device includes a heat - collecting pipeline, a heat - collecting inner shell, a radiation coating, a heat - collecting outer shell, a heat - dissipation structure and a refrigeration structure. The heat - collecting pipelines are evenly distributed on the inner wall surface of the heat - collecting inner shell. The outer wall surface of the heat - collecting inner shell is a radiation coating. The heat - collecting outer shell surrounds the heat - collecting inner shell, and the space between the heat - collecting outer shell and the heat - collecting inner shell is in a vacuum state;

[0015] A heat - aggregation and transfer module, which is used to aggregate the heat generated by the engine using the heat - collecting pipeline, transfer the heat to the heat - collecting inner shell after successful aggregation, and then radiate the heat to the heat - collecting outer shell through the radiation coating;

[0016] A heat - dissipation execution module, which is used to measure the temperature of the outer wall surface of the heat - collecting outer shell, and use the heat - insulating material pre - wrapped on the outer wall surface of the heat - collecting outer shell to dissipate the heat to the external environment of the vehicle, where the thickness of the heat - insulating material can be adaptively adjusted according to the temperature of the outer wall surface;

[0017] An engine refrigeration execution module, which is used to perform temperature regulation on the engine through the refrigeration structure according to the temperature of the outer wall surface. When the temperature of the engine meets the preset temperature threshold, start the fiber optic temperature sensor.

[0018] A vehicle - mounted air - conditioner control module, which is used to adjust the working state of the vehicle - mounted air conditioner according to the actual value of the interior temperature of the vehicle to complete the control of the interior temperature of the vehicle.

[0019] Compared with the prior art, the present application provides a method of first receiving an internal temperature control instruction of an automobile, and starting an engine cooling device according to the internal temperature control instruction of the automobile. The engine cooling device includes a heat collecting pipe, a heat collecting inner shell, a radiation coating, a heat collecting outer shell, a heat dissipation structure and a refrigeration structure. The heat collecting pipes are uniformly distributed on the inner wall surface of the heat collecting inner shell. The outer wall surface of the heat collecting inner shell is a radiation coating. The heat collecting outer shell surrounds the heat collecting inner shell, and the space between the heat collecting outer shell and the heat collecting inner shell is in a vacuum state. The heat generated by the engine is collected by the heat collecting pipes, and after successful collection, it is transferred to the heat collecting inner shell, and then the heat is radiated to the heat collecting outer shell through the radiation coating. It can be seen that the embodiment of the present invention does not directly cool the engine, but first uses the heat collecting pipe as a heat transfer medium, and uses the functions of the evaporation section, the adiabatic section and the condensation section to make the heat transfer process have a buffer stage, improving the rationality of the heat transfer process. Further, the temperature of the outer wall surface of the heat collecting outer shell is measured, and the heat is dissipated to the external environment of the automobile by using the heat insulation material pre-wrapped on the outer wall surface of the heat collecting outer shell. The thickness of the heat insulation material can be adaptively adjusted according to the temperature of the outer wall surface. It should be explained that the function of the heat insulation material is to reduce the temperature influence of the external environment of the automobile in a high-temperature environment, and at the same time reduce the energy consumption of the engine cooling device. Further, according to the temperature of the outer wall surface, the temperature of the engine is adjusted by the refrigeration structure until the temperature of the engine meets the preset temperature threshold, and then the optical fiber temperature sensor is started. The optical fiber temperature sensor is connected to the vehicle-mounted air conditioner. The optical fiber temperature sensor can control the opening state of the vehicle-mounted air conditioner, and measure the actual value of the temperature inside the vehicle by using the optical fiber temperature sensor, and adjust the working state of the vehicle-mounted air conditioner according to the actual value of the temperature inside the vehicle to complete the control of the temperature inside the automobile. It can be seen that the embodiment of the present invention controls the temperature inside the automobile by first buffering and transferring the heat generated by the engine, then dissipating the heat of the engine, cooling the engine by refrigeration, and finally adjusting the temperature inside the automobile by the vehicle-mounted air conditioner, so as to prevent the risk of insufficient heat dissipation performance in the traditional single cooling method. Therefore, the embodiment of the present invention provides a method and system for controlling the temperature inside an automobile, which can improve the intelligent heat transfer of the seat while ensuring driving safety.

[0027] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] An embodiment of the present application provides a method for controlling the interior temperature of an automobile. The execution subject of the method for controlling the interior temperature of the automobile includes, but is not limited to, at least one of electronic devices such as a server, a terminal, etc. that can be configured to execute the method provided by the embodiment of the present application.

The server includes, but is not limited to: a single server, a server cluster, a cloud server, or a cloud server cluster, etc.

[0029] Embodiment:

[0030] Refer to Figure 1 As shown in the flowchart of the method for controlling the interior temperature of an automobile provided by an embodiment of the present invention, Figure 2 The temperature control structure diagram of the method for controlling the interior temperature of an automobile provided by an embodiment of the present invention. In this embodiment, the method for controlling the interior temperature of the automobile includes:

[0031] S1. Receive the interior temperature control instruction of the automobile, and start the engine heat dissipation device according to the interior temperature control instruction of the automobile. The engine heat dissipation device includes a heat accumulation pipeline 1, a heat accumulation inner shell 2, a radiation coating 3, a heat accumulation outer shell 4, a heat dissipation structure 5, and a refrigeration structure 6. The heat accumulation pipeline 1 is uniformly distributed on the inner wall surface of the heat accumulation inner shell 2. The outer wall surface of the heat accumulation inner shell 2 is the radiation coating 3. The heat accumulation outer shell 4 surrounds the heat accumulation inner shell 2, and the gap between the heat accumulation outer shell 4 and the heat accumulation inner shell 2 is in a vacuum state;

[0032] It is understandable that the in-vehicle temperature control instruction in the embodiments of the present invention is generally initiated by the vehicle driver. Exemplarily, when Xiao Zhang drives a car on a hot day, after starting the car, the temperature inside the car begins to rise. Therefore, Xiao Zhang initiates an in-vehicle temperature control instruction, aiming to adjust the in-vehicle temperature to a comfortable ambient temperature suitable for the human body, so as to meet the comfort requirements of the driver and improve the safety of the driver.

[0033] It should be understood that poor heat insulation performance of aging vehicles and the extremely close proximity of some vehicle engines to the driver's cab will cause the engine temperature to be conducted to the interior of the vehicle faster. When the engine is started and the heat generated during its operation cannot be dissipated in time, the accumulated heat causes the engine temperature to be too high, and at the same time, the interior temperature of the vehicle rises rapidly. Therefore, in the embodiments of the present invention, the engine heat dissipation device is started according to the in-vehicle temperature control instruction, and its function is to first control the temperature of the engine, which is the main source of the increase in the interior temperature of the vehicle, and then perform cooling treatment subsequently.

[0034] In addition, both the heat accumulation inner shell and the heat accumulation outer shell are hollow spherical in shape. The spherical diameter of the heat accumulation outer shell is larger than that of the heat accumulation inner shell. Therefore, the heat accumulation outer shell surrounds the heat accumulation inner shell, and the gap between the two spherical shells is in a vacuum state. The heat accumulation pipes are evenly distributed on the inner wall surface of the heat accumulation inner shell, and the outer wall surface of the heat accumulation inner shell is a radiation coating. The function of the heat accumulation pipes is to absorb the heat generated by the engine. Therefore, the heat accumulation pipes can transfer the heat to the heat accumulation inner shell, and then convert the heat into radiation energy through the radiation coating, and radiate and transfer the energy to the heat accumulation outer shell.

[0035] S2. Use the heat accumulation pipes to gather the heat generated by the engine, and after successful gathering, transfer it to the heat accumulation inner shell, and then radiate the heat to the heat accumulation outer shell through the radiation coating;

[0036] It should be explained that during the process of the heat accumulation pipes gathering and transferring the heat to the heat accumulation inner shell, the heat transfer method is heat conduction. The principle is that under a negative pressure state inside the heat accumulation pipes, an appropriate volume of distilled water is injected into the heat accumulation pipes, and then, using the temperature difference between the bottom and the top of the heat accumulation pipes, the distilled water is heated and evaporated into water vapor from the bottom. The water vapor flows upward and finally cools at the top. At this time, the water vapor quickly releases a large amount of heat and re-condenses into a liquid. During this process, the heat is conducted from the bottom of the heat accumulation pipes to the top and then to the heat accumulation inner shell.

[0037] Therefore, specifically, refer to Figure 3 As shown, the use of the heat accumulation pipes to gather the heat generated by the engine, and after successful gathering, transfer it to the heat accumulation inner shell, and then radiate the heat to the heat accumulation outer shell through the radiation coating includes:

[0038] S21. Determine the liquid filling volume of the heat - collecting pipe, where the heat - collecting pipe includes an evaporation section, an adiabatic section, and a condensation section, and the evaporation section, the adiabatic section, and the condensation section are sequentially located at the bottom, middle, and top of the heat - collecting pipe;

[0039] S22. Combine the liquid filling volume and select distilled water with a liquid volume equal to the liquid filling volume and inject it into the evaporation section;

[0040] S23. Start the vacuum pump, use the vacuum pump to evacuate the inside of the heat - collecting pipe, and set the negative pressure state inside the pipe to 1.3×10 -3 Pa;

[0041] S24. Open the switch of the evaporation section, use the evaporation section to absorb the heat generated by the engine, and vaporize the distilled water to obtain water vapor;

[0042] S25. Through the adiabatic section, transport the water vapor upward to the condensation section. After successful transportation, use the condensation section to liquefy the water vapor, and at the same time release the heat generated by liquefaction in the condensation section;

[0043] S26. Transfer the heat generated by liquefaction to the inner heat - collecting shell, heat the radiation coating, and use the radiation coating to radiate the heat generated by liquefaction from the inner heat - collecting shell to the outer heat - collecting shell.

[0044] It should be understood that the liquid filling volume is the volume of distilled water injected into the heat - collecting pipe. If the liquid filling volume is too small, it will lead to insufficient heat transfer efficiency of the heat pipe, and even the heat pipe will be burned out; if the liquid filling volume is too large, it will cause an excessive amount of liquid to accumulate in the condensation section, resulting in too slow heat transfer efficiency.

[0045] It can be explained that in the embodiment of the present invention, the negative pressure state inside the pipe is set to 1.3×10 -3 Pa, which can reduce the boiling point of the injected distilled water under the negative pressure state, and it is easier to evaporate and quickly vaporize after heating.

[0046] Specifically, determining the liquid filling volume of the heat - collecting pipe according to the heat - collecting pipe includes:

[0047] According to the heat - collecting pipe, obtain the factory specification information table of the heat - collecting pipe, and obtain the thermal resistance coefficient of the heat - collecting pipe through the factory specification information table;

[0048] According to the thermal resistance coefficient, calculate the heat - collecting power of the heat - collecting pipe;

[0049] After successful calculation, use the heat - collecting power to determine the liquid filling volume of the heat - collecting pipe.

[0050] It is understandable that the factory specification information table of the heat - collecting pipe includes the length of the evaporation section, the length of the adiabatic section, the length of the condensation section, the inner diameter of the pipe and the heat resistance coefficient. Therefore, the required relevant calculation bases of the heat - collecting pipe can be obtained according to the factory specification information table.

[0051] Furthermore, calculating the heat - collecting power of the heat - collecting pipe according to the heat resistance coefficient includes:

[0052] The heat - collecting power of the heat - collecting pipe is calculated according to the following formula:

[0053]

[0054] Among them, Q represents the heat - collecting power of the heat - collecting pipe, T e represents the average temperature of the evaporation section, T c represents the average temperature of the condensation section, and R represents the heat resistance coefficient of the heat - collecting pipe.

[0055] In addition, compared with the traditional engine heat transfer method, the embodiment of the present invention adds a heat - collecting pipe as a heat transfer medium, and uses the functions of the evaporation section, the adiabatic section and the condensation section to make the heat transfer process have a buffer stage, improving the rationality of the heat transfer process. Otherwise, the heat has nowhere to transfer, resulting in heat overflowing into the car interior, thus rapidly increasing the temperature inside the car.

[0056] S3. Measure the outer wall temperature of the heat - collecting housing, and use the heat - insulating material pre - wrapped on the outer wall of the heat - collecting housing to dissipate the heat to the external environment of the car, where the thickness of the heat - insulating material can be adaptively adjusted according to the outer wall temperature;

[0057] It should be explained that the function of the heat - insulating material is to reduce the temperature influence of the external environment of the car in a high - temperature environment, and at the same time reduce the energy consumption of the engine heat dissipation device.

[0058] Specifically, referring to Figure 4 as shown, dissipating the heat to the external environment of the car by using the heat - insulating material pre - wrapped on the outer wall of the heat - collecting housing includes:

[0059] S31. Obtain the temperature difference between the outer wall temperature and the external environment temperature of the car through the outer wall temperature of the heat - collecting housing;

[0060] S32. Obtain the thickness of the heat - insulating material according to the temperature difference:

[0061] S33. Adjust the heat - insulating material to the thickness and start the heat dissipation structure, where the heat dissipation structure includes a fan switch and fan fins;

[0062] S34. Turn on the fan switch, and the fan fins start to rotate to dissipate the heat to the external environment of the car.

[0063] S4. Perform temperature regulation on the engine through the refrigeration structure according to the temperature of the outer wall surface;

[0064] Specifically, the performing temperature regulation on the engine through the refrigeration structure according to the temperature of the outer wall surface includes:

[0065] Start the refrigeration structure according to the temperature of the outer wall surface, where the refrigeration structure includes a thermoelectric cooler, a thermometer, a thermocouple, and a galvanometer. The thermocouple generates a direct current. The thermometer measures the temperatures at both ends of the thermoelectric cooler when the direct current passes through the thermoelectric cooler, and the galvanometer measures the direct current generated by the thermocouple;

[0066] Open the switch of the thermocouple, obtain the direct current, and measure the direct current using the galvanometer;

[0067] Use the thermometer to read the temperatures at both ends of the thermoelectric cooler when the direct current passes through the thermoelectric cooler;

[0068] Combine the temperatures to calculate the output cooling capacity of the refrigeration structure;

[0069] Adjust the direct current according to the output cooling capacity to achieve temperature regulation of the engine.

[0070] It should be explained that the refrigeration structure adopted in the embodiment of the present invention is a thermoelectric refrigeration system, and the thermoelectric cooler is made of semiconductor materials. When the thermocouple is connected to generate a direct current, the thermocouple, the direct current, and the thermoelectric cooler form a circuit. The direct current flows from the left end of the thermoelectric cooler to the right end, forming a temperature difference at both ends. Therefore, when the direct current passes through the thermoelectric cooler, energy transfer occurs, causing the refrigeration structure to generate cooling capacity.

[0071] Further, the combining the temperatures to calculate the output cooling capacity of the refrigeration structure includes:

[0072] Calculate the output cooling capacity of the refrigeration structure using the following formula:

[0073]

[0074] Where Q c represents the output cooling capacity of the refrigeration structure, N represents the number of pairs of thermocouples, I represents the direct current generated by the thermocouple, T l represents the temperature at the left end of the thermoelectric cooler, T r represents the temperature at the right end of the thermoelectric cooler, a represents the Seebeck coefficient of the thermocouple, R ′ represents the resistance of the thermocouple, and K represents the thermal conductance of the thermocouple.

[0075] Exemplarily, when Zhang drives a car in hot weather, he activates the refrigeration structure and calculates the output refrigeration capacity of the refrigeration structure at this time based on the direct current shown by the ammeter. Since the car components are aging and the heat dissipation is slow, Zhang increases the magnitude of the direct current so that the refrigeration structure outputs more refrigeration capacity to achieve the temperature reduction adjustment of the engine.

[0076] S5. Until the temperature of the engine meets the preset temperature threshold, activate the fiber optic temperature sensor, where the fiber optic temperature sensor is connected to the vehicle air conditioner. The fiber optic temperature sensor can control the on / off state of the vehicle air conditioner, and measure the actual temperature inside the vehicle using the fiber optic temperature sensor;

[0077] It should be explained that in the embodiment of the present invention, the fiber optic temperature sensor is used to measure the temperature inside the car to obtain the actual temperature inside the car. In addition, compared with traditional temperature sensors, the fiber optic temperature sensor has higher measurement accuracy, faster reading speed and more heat-resistant materials. Therefore, it is suitable to use the fiber optic temperature sensor to measure the temperature of the car in harsh high-temperature environments.

[0078] S6. Adjust the working state of the vehicle air conditioner according to the actual temperature value inside the vehicle to complete the control of the temperature inside the car.

[0079] Specifically, the adjusting the working state of the vehicle air conditioner according to the actual temperature value inside the vehicle to complete the control of the temperature inside the car includes:

[0080] Receive the air conditioner state control instruction, and set the temperature threshold inside the vehicle according to the air conditioner state control instruction;

[0081] When the actual temperature value inside the vehicle exceeds the temperature threshold inside the vehicle, use the fiber optic temperature sensor to adjust the vehicle air conditioner to turn on the cooling mode;

[0082] When the actual temperature value inside the vehicle does not exceed the temperature threshold inside the vehicle, use the fiber optic temperature sensor to control the vehicle air conditioner to remain in the non-working state to complete the control of the temperature inside the car.

[0083] Exemplarily, when Zhang drives a car in hot weather, he sets the temperature threshold inside the vehicle to 26°C. When the fiber optic temperature sensor detects that the actual temperature value inside the vehicle exceeds 26°C, since the fiber optic temperature sensor is connected to the vehicle air conditioner, the fiber optic temperature sensor controls the vehicle air conditioner to turn on the cooling mode; when the fiber optic temperature sensor detects that the actual temperature value inside the vehicle does not exceed 26°C, the fiber optic temperature sensor controls the vehicle air conditioner to keep it in the non-activated working state.

[0084] Compared with the prior art, the present application provides a method of first receiving an in-vehicle temperature control instruction and starting an engine cooling device according to the in-vehicle temperature control instruction. The engine cooling device includes a heat-gathering pipeline, a heat-gathering inner shell, a radiation coating, a heat-gathering outer shell, a heat dissipation structure, and a refrigeration structure. The heat-gathering pipelines are evenly distributed on the inner wall surface of the heat-gathering inner shell. The outer wall surface of the heat-gathering inner shell is a radiation coating. The heat-gathering outer shell surrounds the heat-gathering inner shell, and the space between the heat-gathering outer shell and the heat-gathering inner shell is in a vacuum state. The heat generated by the engine is gathered by the heat-gathering pipelines and transferred to the heat-gathering inner shell after successful gathering, and then the heat is radiated to the heat-gathering outer shell through the radiation coating. It can be seen that the embodiment of the present invention does not directly cool the engine, but first uses the heat-gathering pipelines as a heat transfer medium and utilizes the functions of the evaporation section, the adiabatic section, and the condensation section to make the heat transfer process have a buffer stage, improving the rationality of the heat transfer process. Further, the temperature of the outer wall surface of the heat-gathering outer shell is measured, and heat is dissipated to the external environment of the vehicle by using the heat insulation material pre-wrapped on the outer wall surface of the heat-gathering outer shell. The thickness of the heat insulation material can be adaptively adjusted according to the temperature of the outer wall surface. It should be noted that the function of the heat insulation material is to reduce the temperature influence of the external environment of the vehicle in a high-temperature environment and at the same time reduce the energy consumption of the engine cooling device. Further, according to the temperature of the outer wall surface, the refrigeration structure is used to adjust the temperature of the engine until the temperature of the engine meets the preset temperature threshold, and then an optical fiber temperature sensor is started. The optical fiber temperature sensor is connected to the vehicle-mounted air conditioner. The optical fiber temperature sensor can control the opening state of the vehicle-mounted air conditioner and measure the actual in-vehicle temperature value by using the optical fiber temperature sensor, and adjust the working state of the vehicle-mounted air conditioner according to the actual in-vehicle temperature value to complete the control of the in-vehicle temperature. It can be seen that the embodiment of the present invention controls the in-vehicle temperature by first buffering and transferring the heat generated by the engine, then dissipating the heat of the engine, simultaneously cooling the engine by refrigeration, and finally adjusting the in-vehicle temperature by the vehicle-mounted air conditioner to prevent the risk of insufficient heat dissipation performance using a traditional single cooling method. Therefore, a method and a system for controlling the in-vehicle temperature provided by the embodiment of the present invention can improve the technical solution of the seat heat transfer intelligence while ensuring driving safety.

[0086] Figure 5 is a block diagram of a control system for the in-vehicle temperature according to an embodiment of the present application. As Figure 5As shown, the control system 100 for the interior temperature of an automobile according to an embodiment of the present application includes: a heat dissipation device activation module 110, configured to receive an interior temperature control instruction of the automobile and activate an engine heat dissipation device according to the interior temperature control instruction of the automobile, where the engine heat dissipation device includes a heat accumulation pipe, a heat accumulation inner shell, a radiation coating, a heat accumulation outer shell, a heat dissipation structure, and a refrigeration structure, where the heat accumulation pipes are evenly distributed on the inner wall surface of the heat accumulation inner shell, the outer wall surface of the heat accumulation inner shell is a radiation coating, the heat accumulation outer shell surrounds the heat accumulation inner shell, and the gap between the heat accumulation outer shell and the heat accumulation inner shell is in a vacuum state; a heat accumulation and transfer module 120, configured to accumulate the heat generated by the engine using the heat accumulation pipes, transfer the heat to the heat accumulation inner shell after successful accumulation, and then radiate the heat to the heat accumulation outer shell through the radiation coating; a heat dissipation execution module 130, configured to measure the temperature of the outer wall surface of the heat accumulation outer shell and dissipate the heat to the external environment of the automobile using heat insulation materials pre-wrapped on the outer wall surface of the heat accumulation outer shell, where the thickness of the heat insulation materials can be adaptively adjusted according to the temperature of the outer wall surface; an engine refrigeration execution module 140, configured to perform temperature adjustment on the engine through the refrigeration structure according to the temperature of the outer wall surface, start an optical fiber temperature sensor until the temperature of the engine meets a preset temperature threshold, where the optical fiber temperature sensor is connected to an in-vehicle air conditioner, the optical fiber temperature sensor can control the on / off state of the in-vehicle air conditioner, and measure the actual value of the interior temperature of the vehicle using the optical fiber temperature sensor; and an in-vehicle air conditioner control module 150, configured to adjust the working state of the in-vehicle air conditioner according to the actual value of the interior temperature of the vehicle to complete the control of the interior temperature of the automobile.
