Technical Field

[0002] With the continuous development of technology, cars are becoming increasingly intelligent. For example, in addition to supporting traditional functions such as radio, music and video playback, and navigation, car infotainment systems (IVI, also known as vehicle infotainment systems) also support more advanced features such as navigation, multimedia playback, Bluetooth connectivity, vehicle settings, voice control, and vehicle interconnection.

[0003] However, the more powerful the in-vehicle infotainment system, the more heat it generates during operation. This heat is usually directly dissipated, resulting in low heat utilization.

Detailed Implementation

[0062] This application provides a heat recovery system, method, apparatus, equipment, and medium, which solves the technical problem of low heat utilization caused by direct heat loss from vehicle systems in the prior art.

[0063] The technical solution of this application embodiment is to solve the above-mentioned technical problems, and the general idea is as follows:

[0064] This embodiment obtains the target operating state of the air conditioning circuit; when the target operating state is cooling, it controls the operation of the cooling sub-circuit and the second sub-circuit; when the target operating state is heating, it controls the operation of the heating sub-circuit and the first sub-circuit, or controls the operation of the heating sub-circuit, the first sub-circuit, and the second sub-circuit. It can be seen that this embodiment achieves heat exchange between the air conditioning circuit and the vehicle system's heat dissipation circuit through the water-cooled condenser 8. In heating mode, it recovers heat from the vehicle system, thereby reducing the energy consumption of the air conditioning equipment using the vehicle's power supply, improving the heat recovery rate of the vehicle system, that is, improving the utilization rate of the heat generated by the vehicle system during operation, achieving effective utilization of the vehicle's waste heat, improving the heating comfort of the passenger compartment, reducing the overall vehicle power consumption, and thus increasing the vehicle's range in low temperatures. In cooling mode, it reduces the impact of the vehicle system's heat on the air conditioning circuit's cooling, mainly using the radiator to dissipate heat from the vehicle system, minimizing the energy consumption of the air conditioning equipment using the vehicle's power supply, and extending the vehicle's power supply's range.

[0065] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0066] First, it should be clarified that the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0067] With the continuous development of technology, cars are becoming increasingly intelligent. For example, in addition to supporting traditional functions such as radio, music and video playback, and navigation, car infotainment systems (IVI) also support more advanced features such as navigation, multimedia playback, Bluetooth connectivity, vehicle settings, voice control, and vehicle connectivity.

[0068] The in-vehicle infotainment system (IVI) offers the following functions: real-time navigation, map display, and route planning to help users find their destination and provide navigation guidance; it supports audio and video playback, including listening to the radio, playing music, and watching videos. Through Bluetooth technology, drivers and passengers can connect to their mobile phones or other Bluetooth devices for hands-free calling, music playback, and message reading. It provides various vehicle settings and adjustments, such as air conditioning, seat heating, and vehicle driving modes. It supports voice recognition technology, allowing drivers to control and operate the IVI system via voice commands, improving safety and convenience. It supports internet connectivity, enabling drivers and passengers to access real-time traffic information, weather forecasts, online music, and applications.

[0069] However, the more powerful the in-vehicle infotainment system, the more heat it generates during operation. This heat is usually directly dissipated, resulting in low heat utilization. Therefore, improving the utilization rate of heat generated by the in-vehicle infotainment system during operation is an urgent problem to be solved.

[0070] To address the aforementioned problems, this embodiment provides the following: Figure 1 The heat recovery system shown includes a controller (not in...) Figure 1 As shown in the figure, the air conditioning circuit and the vehicle system cooling circuit are connected by a water-cooled condenser 8 for heat exchange.

[0071] The air conditioning circuit includes a gas-liquid separator 1, a compressor 2, a first full-way shut-off valve 3, a water-cooled condenser 8, a first electronic expansion valve 6, an evaporator 4, an in-vehicle condenser 5, a second electronic expansion valve 7, and a second full-way shut-off valve 9.

[0072] Gas-liquid separator 1, compressor 2, first full-way shut-off valve 3, water-cooled condenser 8, first electronic expansion valve 6, evaporator 4, and gas-liquid separator 1 are connected in sequence to form a refrigeration sub-circuit;

[0073] Gas-liquid separator 1, compressor 2, in-vehicle condenser 5, second electronic expansion valve 7, water-cooled condenser 8, second full-way shut-off valve 9, and gas-liquid separator 1 are connected in sequence to form a heating sub-circuit;

[0074] The vehicle infotainment system cooling circuit includes an electronic water pump 10, a water-cooled condenser 8, a vehicle infotainment system water-cooling component 14, a three-way proportional valve 13, and a water-cooled radiator 12; wherein the vehicle infotainment system water-cooling component 14 refers to the water pipes covering the surface of the vehicle infotainment system.

[0075] The electronic water pump 10, the water-cooled condenser 8, the vehicle infotainment system water-cooled component 14, the first port A of the three-way proportional valve 13, the third port C of the three-way proportional valve 13, and the electronic water pump 10 are connected in sequence to form the first sub-circuit.

[0076] The electronic water pump 10, water-cooled condenser 8, vehicle infotainment system water-cooled component 14, first port A of three-way proportional valve 13, second port B of three-way proportional valve 13, water-cooled radiator 12 and electronic water pump 10 are connected in sequence to form the second sub-circuit.

[0077] In actual operation, in addition to the circuits and related equipment mentioned above, some sensors are also installed. For example... Figure 1 The system includes corresponding pressure and temperature sensors PT1 and PT2, as well as a temperature sensor T used to measure the temperature of the vehicle's cooling circuit. The relevant sensors can be configured according to actual conditions; this embodiment does not impose any limitations on this.

[0078] The controller is electrically connected to the cooling sub-circuit, the heating sub-circuit, the first sub-circuit, and the second sub-circuit, respectively.

[0079] Specifically, the controller is electrically connected to the following devices:

[0080] Electronic control devices including first full-way shut-off valve 3, first electronic expansion valve 6, second electronic expansion valve 7, second full-way shut-off valve 9, electronic water pump 10, fan 11, three-way proportional valve 13, PT1, PT2, T, etc.

[0081] This embodiment couples the air conditioning circuit and the vehicle infotainment system cooling circuit through a water-cooled condenser, enabling the air conditioning circuit to recover heat from the vehicle infotainment system cooling circuit when in heating mode, thereby improving the heat utilization rate of the vehicle infotainment system, reducing vehicle energy consumption, and extending vehicle driving range.

[0082] Based on the same inventive concept, this embodiment provides as follows: Figure 2The heat recovery method shown is applied to a heat recovery system as described above, specifically to a controller of a heat recovery system, and includes steps S21-S23.

[0083] Step S21: Obtain the target operating status of the air conditioning circuit;

[0084] Step S22: When the target operating state is cooling state, control the operation of the cooling sub-circuit and the second sub-circuit.

[0085] Step S23: When the target operating state is heating state, control the operation of the heating sub-circuit and the first sub-circuit, or control the operation of the heating sub-circuit, the first sub-circuit and the second sub-circuit.

[0086] The heat recovery method provided in this embodiment can be executed by the vehicle controller of the vehicle where the air conditioning circuit is located, or by the air conditioning controller corresponding to the air conditioning circuit. This embodiment will only take the air conditioning controller as the execution subject for subsequent explanation.

[0087] Regarding step S21, obtain the target operating status of the air conditioning circuit.

[0088] The operating status of an air conditioning circuit includes both active and inactive states. The active state includes cooling and heating states. The operating status of the air conditioning circuit can be determined by reading its corresponding status identifier.

[0089] When the target operating state is non-operating, it means that the heat generated by the vehicle system can only be dissipated, therefore it is necessary to control the operation of the second sub-loop. Combined with... Figure 1 As shown, the first port A and the second port B of the three-way proportional valve 13 are connected, the first port A and the third port C of the three-way proportional valve 13 are closed, and the water-cooled radiator 12 is operated, so that the second sub-circuit is in a conducting state, so as to achieve the purpose of heat dissipation of the vehicle system and ensure that the vehicle system operates at a suitable temperature.

[0090] If the target operating state is cooling, step S22 can be executed. If the target operating state is heating, step S23 can be executed.

[0091] Regarding step S22, when the target operating state is the cooling state, the cooling sub-circuit and the second sub-circuit are controlled to operate.

[0092] When the target operating state is cooling, the operation of the cooling sub-circuit and the second sub-circuit is controlled, which can be combined with Figure 1 The following explanation is provided.

[0093] The second electronic expansion valve 7 and the second full-way shut-off valve 9 are closed, while the first full-way shut-off valve 3 and the first electronic expansion valve 6 are opened, thus putting the refrigeration sub-circuit into a conductive state. In other words, the cold air generated by the compressor 2 will sequentially pass through the first full-way shut-off valve 3, the water-cooled condenser 8, the first electronic expansion valve 6, the evaporator 4, and the gas-liquid separator 1, thereby delivering cold air to the corresponding passenger compartment space of the air conditioning circuit to achieve the purpose of cooling.

[0094] In cooling mode, the heat generated by the vehicle's infotainment system can only be dissipated and cannot be used for cooling the air conditioning circuit. Therefore, it is necessary to control the operation of the second sub-circuit, such as... Figure 1 As shown, specifically, the first port A and the second port B of the three-way proportional valve 13 are connected, and the first port A and the third port C of the three-way proportional valve 13 are closed, controlling the water-cooled radiator 12 to operate, so that the second sub-circuit is in a conducting state, in order to achieve the purpose of heat dissipation of the vehicle system, ensure that the vehicle system operates at a suitable temperature, reduce the negative impact of the water-cooled condenser on the cooling sub-circuit, minimize the cooling energy consumption of the cooling sub-circuit, and improve the utilization rate of vehicle electrical energy.

[0095] Regarding step S23, when the target operating state is heating state, control the operation of the heating sub-circuit and the first sub-circuit, or control the operation of the heating sub-circuit, the first sub-circuit and the second sub-circuit.

[0096] When the target operating state is heating mode, the operation of the heating sub-circuit and the first sub-circuit can be controlled, or the operation of the heating sub-circuit, the first sub-circuit, and the second sub-circuit can be controlled. Both methods can transfer the heat generated by the vehicle system to the air conditioning circuit through the water-cooled condenser, thereby enabling the air conditioning circuit to recover and reuse the heat generated by the vehicle system, improving the utilization rate of the heat generated by the vehicle system.

[0097] Specifically, step S23 may include steps S231-S233.

[0098] Step S231: When the target operating state is heating state, monitor the target heating temperature corresponding to the air conditioning circuit and the actual operating temperature corresponding to the vehicle system heat dissipation circuit.

[0099] The target heating temperature is set by the user and represents the desired temperature for the passenger compartment. The actual operating temperature is the actual temperature of the coolant in the vehicle's infotainment system's cooling circuit; specifically, it can be determined using... Figure 1 The temperature sensor T collects data. The target heating temperature changes according to user adjustments, and is updated when the user adjusts the target heating temperature. The actual operating temperature changes in real time according to the operating load of the vehicle system, and can be collected at a preset frequency, such as updating the actual operating temperature every minute.

[0100] When the target operating state is heating, the relationship between the actual operating temperature and the first preset threshold is determined. The first preset threshold is used to determine whether the vehicle's heat recovery is necessary. It can be set according to the actual situation, for example, it can be 15℃. When the actual operating temperature is less than or equal to the first preset threshold, step S232 can be executed. When the actual operating temperature is greater than the first preset threshold, step S233 can be executed.

[0101] Step S232: When the actual operating temperature is less than or equal to the first preset threshold, control the operation of the heating sub-circuit and the first sub-circuit, and determine the first heating power of the heating sub-circuit according to the actual space temperature of the crew cabin space (space to be heated) corresponding to the heating sub-circuit and the target heating temperature; the first preset threshold is less than the target heating temperature.

[0102] When the actual operating temperature is less than or equal to the first preset threshold, it means that the vehicle's infotainment system generates relatively little heat. In this case, the air conditioning cannot rely solely on the system's heat for heating, necessitating control of the heating sub-circuit. The air conditioning system determines the first heating power of the heating sub-circuit based on the actual temperature of the passenger compartment and the target heating temperature. The system then controls the heating sub-circuit to operate at this first heating power, bringing the actual temperature of the passenger compartment closer to or equal to the target heating temperature. Figure 1 As shown, specifically, the second electronic expansion valve 7 and the second full-way shut-off valve 9 are turned on, while the first electronic expansion valve 6 and the first full-way shut-off valve 3 are turned off, so that the heating sub-circuit can operate.

[0103] When the actual operating temperature is less than or equal to the first preset threshold, it may be because the vehicle has just started and the temperature of the vehicle system's cooling circuit has not yet risen. However, as the vehicle runs for longer, the actual operating temperature will increase. To accelerate the increase in the actual operating temperature and prevent the water-cooled radiator 12 from cooling the vehicle system's cooling circuit, the operation of the first sub-circuit is controlled. This means controlling the first port A and the second port B of the three-way proportional valve 13 to close, controlling the first port A and the third port C of the three-way proportional valve 13 to open, and controlling the water-cooled radiator 12 to stop, thus keeping the first sub-circuit in a conducting state.

[0104] Step S233: When the actual operating temperature is greater than the first preset threshold, control the operation of the heating sub-circuit and the first sub-circuit, or control the operation of the heating sub-circuit, the first sub-circuit and the second sub-circuit, and determine the second heating power of the heating sub-circuit based on the actual space temperature, the actual operating temperature and the target heating temperature.

[0105] As time goes on, the actual operating temperature will gradually exceed the first preset threshold. When the actual operating temperature is greater than the first preset threshold, it means that the heat generated by the vehicle system has reached a certain level and can be recovered by the air conditioning circuit. At this time, the heating sub-circuit can be controlled to continue working. The second heating power of the heating sub-circuit is determined based on the actual space temperature, the actual operating temperature, and the target heating temperature to heat the passenger compartment.

[0106] When the actual operating temperature exceeds the first preset threshold, it is necessary to determine the relationship between the actual operating temperature and the target heating temperature. This is used to determine the effectiveness of heat recovery in the vehicle system and to adjust the second heating power of the heating sub-circuit in real time. This process specifically includes steps S2331-S2333.

[0107] Step S2331: When the actual operating temperature is greater than the first preset threshold and the actual operating temperature is less than or equal to the target heating temperature, control the operation of the heating sub-circuit and the first sub-circuit.

[0108] When the actual operating temperature is greater than the first preset threshold but less than or equal to the target heating temperature, it means that all the heat from the vehicle system can be recovered by the air conditioning circuit without causing overheating of the air conditioning circuit. At the same time, the air conditioning equipment needs to use some additional heat to make the passenger compartment reach the target heating temperature.

[0109] It should be noted that some heat in the vehicle's infotainment system's cooling circuit is lost through the water-cooling pipes. Therefore, the total heat of the vehicle's infotainment system mentioned above does not include the heat lost through the water-cooling pipes. Thus, when the actual operating temperature is greater than the first preset threshold and less than or equal to the target heating temperature, the heating sub-circuit and the first sub-circuit can be controlled to operate.

[0110] Step S2332: When the actual operating temperature is greater than the target heating temperature, and the difference between the actual operating temperature and the target heating temperature is less than or equal to the second preset threshold, control the operation of the heating sub-circuit and the first sub-circuit.

[0111] As time progresses, the actual operating temperature continues to increase. When the actual operating temperature exceeds the target heating temperature, and the difference between the two is less than or equal to the second preset threshold, it means that the heat generated by the vehicle's infotainment system can provide most of the heat for the air conditioning circuit, allowing the temperature in the passenger compartment to reach the target heating temperature. At this point, the heating sub-circuit and the first sub-circuit can be controlled to recover a higher proportion of the heat generated by the vehicle's infotainment system. This not only reduces the onboard electrical energy used by the air conditioning equipment but also ensures the heating needs of the passenger compartment, while also improving the heat recovery rate of the infotainment system. The second preset threshold can be determined based on the actual needs of the vehicle, for example, it could be 10°C.

[0112] Step S2333: When the actual operating temperature is greater than the target heating temperature, and the difference between the actual operating temperature and the target heating temperature is greater than the second preset threshold, control the operation of the heating sub-circuit, the first sub-circuit, and the second sub-circuit.

[0113] When the actual operating temperature exceeds the target heating temperature, and the difference between the two exceeds the second preset threshold, it means that the heat generated by the vehicle's infotainment system can essentially cover the heat required by the air conditioning circuit, allowing the temperature in the passenger compartment to reach the target heating temperature. However, to prevent the infotainment system from malfunctioning due to excessive heat generation, the operation of the heating sub-circuit, the first sub-circuit, and the second sub-circuit can be controlled to recover a higher proportion of the heat generated by the infotainment system. Simultaneously, the water-cooled radiator 12 in the infotainment system's cooling circuit can remove excess heat from the circuit, reducing the likelihood of the infotainment system overheating. In this way, the heat from the infotainment system essentially covers all the energy required for vehicle heating, reducing the onboard electrical energy used by the air conditioning equipment, ensuring the heating needs of the passenger compartment, and improving the heat recovery rate of the infotainment system.

[0114] Specifically, controlling the operation of the first sub-circuit and the second sub-circuit involves controlling the opening degree between the first port A and the second port B of the three-way proportional valve 13 to the first opening degree, controlling the opening degree between the first port A and the third port C of the three-way proportional valve 13 to the second opening degree, and controlling the operation of the water-cooled radiator 12, so that both the first sub-circuit and the second sub-circuit are in a conducting state.

[0115] The first and second opening degrees can be adjusted based on the difference between the target heating temperature and the actual operating temperature. The greater the difference between the actual operating temperature and the target heating temperature, the larger the first opening degree and the smaller the second opening degree. The heat dissipation efficiency of the water-cooled radiator 12 also needs to be higher, so that more and faster coolant in the vehicle system's heat dissipation circuit passes through the water-cooled radiator 12 to achieve the purpose of heat dissipation.

[0116] The less the actual operating temperature exceeds the target heating temperature, the smaller the initial opening and the larger the second opening. This also requires a lower heat dissipation efficiency from the water-cooled radiator 12. This results in less and slower coolant flowing through the radiator 12 in the vehicle's cooling circuit, reducing its heat dissipation and allowing more heat to be recovered by the air conditioning circuit. The heat dissipation efficiency of the water-cooled radiator 12 can be adjusted by controlling the internal coolant flow rate or the fan speed 11.

[0117] In summary, this embodiment obtains the target operating state of the air conditioning circuit; when the target operating state is cooling, it controls the operation of the cooling sub-circuit and the second sub-circuit; when the target operating state is heating, it controls the operation of the heating sub-circuit and the first sub-circuit, or controls the operation of the heating sub-circuit, the first sub-circuit, and the second sub-circuit. It can be seen that this embodiment achieves heat exchange between the air conditioning circuit and the vehicle system's heat dissipation circuit through the water-cooled condenser 8. In heating mode, it recovers heat from the vehicle system, thereby reducing the energy consumption of the air conditioning equipment using the vehicle's power supply, improving the heat recovery rate of the vehicle system, that is, improving the utilization rate of the heat generated by the vehicle system during operation, achieving effective utilization of the vehicle's waste heat, improving the heating comfort of the passenger compartment, reducing the overall vehicle power consumption, and thus increasing the vehicle's range in low temperatures. In cooling mode, it reduces the impact of the vehicle system's heat on the air conditioning circuit's cooling, mainly using the radiator to dissipate heat from the vehicle system, minimizing the energy consumption of the air conditioning equipment using the vehicle's power supply, and extending the vehicle's power supply's range.
