Detailed Implementation

[0017] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] The present invention proposes a control method for dynamically adjusting the vehicle interior temperature using external airflow to solve the problem of high energy consumption due to reliance on air conditioning systems (cooling / heating). By introducing external airflow into the vehicle interior through a front fairing, and using the temperature difference between the inside and outside environments to regulate the interior temperature in certain environments, the use of the air conditioning and blower in the vehicle is reduced in some environments, thereby reducing the vehicle's reliance on air conditioning for temperature control and the energy consumption caused by air conditioning reliance.

[0019] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0020] Figure 1 This is a schematic flowchart of a control method for dynamically adjusting the interior temperature of a vehicle using external airflow, provided in an embodiment of the present invention. Figure 1 As shown, the embodiments of the present invention propose Figure 1 A control method for dynamically adjusting the interior temperature of a vehicle using external airflow is provided in the prior art and applied to a control system. The control system includes a front fairing, connecting pipes, a temperature regulation module, an external temperature sensor, and an interior temperature sensor. The front fairing is located at the front of the vehicle and is used to input external airflow and increase the air pressure difference between the external airflow and the interior environment. The airflow input through the front fairing passes through the connecting pipes and is output to the air outlet of the temperature regulation module. The method includes: Step 100: Monitor the ambient temperature outside the vehicle and the ambient temperature inside the vehicle using the outside temperature sensor and the inside temperature sensor. Step 110: Based on the external ambient temperature of the vehicle, the internal ambient temperature of the vehicle, and the vehicle speed, adjust the temperature control mode of the vehicle; wherein, the temperature control mode of the vehicle is related to the working status of the front fairing and the working status of the temperature adjustment module. Step 120: Based on the vehicle's current temperature control mode, dynamically adjust the vehicle interior temperature.

[0021] In this exemplary embodiment, the front fairing can be located behind the front bumper or grille, and has a built-in openable and closable air deflector (electrically controlled). It opens at high speeds to increase airflow capture and closes at low speeds to reduce wind resistance. It can replace the air conditioning blower when controlling the ambient temperature inside the vehicle.

[0022] In this exemplary embodiment, the temperature regulation module may include a miniature heat exchanger (such as a semiconductor cooling chip or a small liquid cooling cycle) integrated in the air duct to pre-cool when the outside air temperature is unsuitable (such as high-temperature airflow in summer) or preheat when the airflow is low-temperature in winter.

[0023] In this exemplary embodiment, the sensor group may include an outside temperature sensor, an inside temperature sensor, a vehicle speed sensor, a humidity sensor, and a solar radiation sensor (detecting sunlight intensity).

[0024] In this exemplary embodiment, the controller can adjust the opening of the deflector and the temperature regulation module and other actuators according to the vehicle's speed and ventilation path.

[0025] In this exemplary embodiment, the connecting pipe can connect the baffle plate and the air conditioning inlet.

[0026] In this exemplary embodiment, Figure 2 This is a schematic diagram of a control system for dynamically adjusting the interior temperature of a vehicle based on external airflow, provided as an embodiment of the present invention. Figure 2 As shown, the control system for dynamically adjusting the interior temperature based on external airflow includes: 1. Front fairing; 2. Connecting pipe; 3. Air conditioning blower; 4. First vehicle pressure relief valve; 5. In-vehicle temperature sensor; 6. Second vehicle pressure relief valve; 7. Solar radiation sensor; 8. Air conditioning blower; 9. Outside vehicle temperature sensor; 10. Vehicle speed signal collector; 11. Air conditioning blower; and 12. Air conditioning blower.

[0027] The connecting pipe 2 connects the front fairing 1 to the air conditioning blower 3, air conditioning blower 11, and air conditioning blower 12. The first vehicle pressure relief valve 4 and the second vehicle pressure relief valve 6 are both used to balance the air pressure difference between the inside and outside of the vehicle. The solar radiation sensor 7 is used to monitor sunlight intensity. The vehicle speed signal acquisition unit 10 is used to provide vehicle speed information to the controller. The temperature control module may include an air conditioner.

[0028] This application introduces outside airflow into the vehicle through a front fairing and uses the temperature difference between the inside and outside of the vehicle to regulate the interior temperature in certain environments. This reduces the use of the air conditioner and blower in certain environments, thereby reducing the vehicle's reliance on air conditioning for temperature control and the energy consumption caused by air conditioning reliance.

[0029] In some instances, the vehicle's temperature control modes include at least a first temperature control mode, a second temperature control mode, and a third temperature control mode; The method of adjusting the vehicle's temperature control mode based on the vehicle's external ambient temperature, the vehicle's interior ambient temperature, and the vehicle's speed includes: Based on the external ambient temperature of the vehicle, the internal ambient temperature of the vehicle, and the vehicle speed, the temperature control mode of the vehicle is adjusted to one of the first temperature control mode, the second temperature control mode, and the third temperature control mode. In the first temperature control mode, the front fairing is open and the temperature adjustment module is not in operation; in the second temperature control mode, the front fairing is open and the temperature adjustment module is in cooling mode; in the third temperature control mode, the front fairing is open and the temperature adjustment module is in heating mode.

[0030] In this exemplary embodiment, adjusting the vehicle's temperature control mode based on the vehicle's external ambient temperature, the vehicle's interior ambient temperature, and the vehicle's speed includes: If the vehicle's speed is greater than the first speed, the vehicle's interior temperature is greater than the vehicle's exterior temperature, and the vehicle's exterior temperature is greater than the first threshold but less than the second threshold, then the vehicle's temperature control mode is adjusted to the first temperature control mode. If the vehicle's speed is greater than the first speed, the vehicle's interior temperature is greater than the vehicle's exterior temperature, and the vehicle's exterior temperature is greater than the second threshold, then the vehicle's temperature control mode is adjusted to the second temperature control mode. If the vehicle's speed is greater than a first speed, the interior temperature is greater than the exterior temperature, and the exterior temperature is less than a third threshold, then the vehicle's temperature control mode is adjusted to the third temperature control mode; wherein the second threshold is greater than the first threshold, and the first threshold is greater than the third threshold.

[0031] In this exemplary embodiment, the first vehicle speed can be set arbitrarily, for example, a speed between 80 km / h and 120 km / h. The first threshold can be 20-26℃, the second threshold can be a temperature above 35℃, and the third threshold can be a temperature below 15℃. For example, if the external ambient temperature T_out < the internal ambient temperature T_in and T_out is within a comfortable range (e.g., 20-26℃), then the "natural cooling mode" is activated: the front spoiler is opened to introduce high-speed airflow (using air kinetic energy for cooling); if the vehicle speed V > 80 km / h, the airflow cooling effect is significant, and the air conditioning can be turned off.

[0032] If T_out > T_in and T_out is too high (e.g., >35℃), then the "pre-cooling mode" is activated: the deflector is partially opened, the airflow enters the heat exchanger through the air duct splitter, and the air conditioning pre-cools the air before sending it into the vehicle; if the vehicle speed V > 80km / h, the high-speed airflow itself has a certain cooling effect, which can reduce the power of the heat exchanger.

[0033] In winter (T_out < 15℃), activate the "preheating mode": airflow from outside the vehicle passes through the air conditioning heat exchanger and is then sent into the vehicle to avoid direct cold air blowing. In some instances, the front fairing incorporates a diffuser plate; The method of adjusting the vehicle's temperature control mode based on the vehicle's external ambient temperature, the vehicle's interior ambient temperature, and the vehicle's speed includes: When the front fairing is in the open state, the opening degree of the fairing is adjusted according to the vehicle speed.

[0034] In this exemplary embodiment, the deflector opening is adjusted according to the vehicle speed (e.g., the opening is increased at high speeds to utilize more airflow energy).

[0035] In this exemplary embodiment, adjusting the vehicle's temperature control mode based on the vehicle's external ambient temperature, the vehicle's interior ambient temperature, and the vehicle's speed includes: When the front fairing is open, the opening degree of the fairing is adjusted according to the external ambient temperature, the internal ambient temperature, and the vehicle speed. For example, the opening degree is increased at high speeds to utilize more airflow energy, or the opening degree is increased when the internal ambient temperature is higher than the external ambient temperature and the temperature difference between the two is significant.

[0036] In some instances, the connecting pipeline includes a main air duct and a bypass air duct; wherein, an air duct splitter is provided between the main air duct and the bypass air duct; and phase change material (PCM) modules are provided in the main air duct and part of the bypass air duct. The method of adjusting the vehicle's temperature control mode based on the vehicle's external ambient temperature, the vehicle's interior ambient temperature, and the vehicle's speed includes: When the front fairing is open, the ventilation path of the airflow from outside the vehicle into the vehicle is adjusted by the air duct diverter according to the ambient temperature outside the vehicle and the ambient temperature inside the vehicle; the ventilation path includes the main air duct and part of the bypass air duct.

[0037] In this exemplary embodiment, the bypass duct may include multiple ducts, some of which have a built-in PCM module, while others do not. Specifically, based on the vehicle's external ambient temperature and the vehicle's internal ambient temperature, the ventilation path of the external airflow entering the vehicle can be adjusted by the air duct splitter, selecting either a bypass duct without a built-in PCM module or one with a built-in PCM module. For example, when the vehicle's internal ambient temperature is greater than the vehicle's external ambient temperature and the vehicle's external ambient temperature is greater than a second threshold, a bypass duct with a built-in PCM module is selected.

[0038] If the interior temperature of the vehicle is greater than the exterior temperature, and the exterior temperature is greater than a first threshold but less than a second threshold, a bypass duct without a built-in PCM module is selected. This allows for the appropriate bypass duct to be rotated based on the required interior and exterior temperatures.

[0039] In some instances, the step of regulating the ventilation path of airflow from outside the vehicle into the vehicle through the air duct splitter based on the external ambient temperature and the internal ambient temperature includes: In the second or third temperature control mode, when the airflow outside the vehicle enters the bypass duct with the PCM module containing the phase change material, the airflow temperature at the inlet of the PCM module and the airflow temperature at the outlet of the PCM module are obtained. The phase transition state of the PCM module is determined based on the airflow temperature at the inlet and outlet of the PCM module. The operating state of the temperature regulation module is adjusted based on the phase transition state of the PCM module.

[0040] In this exemplary embodiment, regulating the operating state of the temperature control module based on the phase transition state of the PCM module includes: If the phase change state of the PCM module is the melting state, then the working state of the temperature regulation module is adjusted to the non-cooling state. If the phase change state of the PCM module is liquid, then the operating state of the temperature regulation module is adjusted to be non-cooling. If the phase change state of the PCM module is liquid heating state, then the working state of the temperature regulation module is adjusted to non-cooling state. If the phase change state of the PCM module is solidification, then the operating state of the temperature regulation module is adjusted to be non-heating. If the phase change state of the PCM module is solid state, then the working state of the temperature regulation module is adjusted to heating state. If the phase change state of the PCM module is solid-state heating, then the working state of the temperature regulation module is adjusted to heating state.

[0041] In this exemplary embodiment, the phase change material (PCM) absorbs or releases a large amount of latent heat when undergoing a phase change (such as from solid to liquid, or from liquid to solid), while its own temperature remains almost constant. When the temperature of the air flowing into the duct is higher than the phase change temperature of the PCM, the PCM melts and absorbs heat, thus cooling the air.

[0042] When the temperature of the air flowing into the duct is lower than the phase change temperature of the PCM, the PCM condenses and releases heat, thus heating the air.

[0043] This process does not require electricity; it relies solely on the heat exchange between the air and the PCM module to achieve temperature "peak shaving and valley filling," smoothing out airflow temperature fluctuations.

[0044] In this design, the PCM is encapsulated within numerous tiny, highly thermally conductive capsules or honeycomb cavities (such as aluminum or copper finned tubes or plate structures) to form the PCM heat exchange core. This design significantly increases the contact area between the PCM and the airflow for heat exchange.

[0045] Among them, the PCM heat exchange core is made into a pluggable standardized module, which is convenient to install in the air ducts of different vehicle models, and also facilitates later maintenance or replacement of PCMs with different phase change temperatures.

[0046] The PCM module is installed directly in the main air duct after the airflow acquisition module and before the airflow splitter. All airflow introduced outside the vehicle must pass through this module for preliminary temperature pretreatment.

[0047] Among them, a PCM duct with a built-in PCM module is set up in parallel with the main air duct. Through the control of the air valve, the airflow can be completely, partially or not flow through the PCM duct as needed, so as to achieve more flexible control.

[0048] If the phase change state of the PCM module is the melting state, then the working state of the temperature regulation module is adjusted to the non-cooling state. At this time, the active cooling (semiconductor air conditioner) is greatly reduced or turned off, and the PCM is used to cool down first.

[0049] If the phase change state of the PCM module is liquid, then the working state of the temperature regulation module is adjusted to non-cooling state. At this time, active cooling is started or enhanced, and the PCM is marked to wait for the "regeneration" opportunity.

[0050] If the phase change state of the PCM module is liquid heating, then the working state of the temperature regulation module is not cooling. At this time, it relies entirely on active cooling and looks for opportunities to "regenerate" the PCM (such as introducing cool night air).

[0051] If the phase change state of the PCM module is solidification, then the working state of the temperature regulation module is adjusted to non-heating state. At this time, the active heating is greatly reduced or turned off, and the PCM is used for preheating first.

[0052] If the phase change state of the PCM module is solid state, then the working state of the temperature regulation module is adjusted to heating state. At this time, active heating is started or enhanced, and the PCM is marked to wait for the "charging" opportunity.

[0053] If the phase change state of the PCM module is solid-state heating, then the working state of the temperature regulation module is adjusted to heating state. At this time, it relies entirely on active heating and seeks opportunities to "charge" the PCM (such as introducing warm air during the day).

[0054] In specific control applications, the heat exchanger power can be adjusted according to solar radiation S (pre-cooling / preheating is enhanced during strong sunlight); the deflector opening and pre-cooling / preheating power can be intelligently adjusted according to air conditioning temperature and air volume.

[0055] For example, consider a summer highway driving scenario: Vehicle speed V = 100 km / h, outside temperature T_out = 32℃, inside temperature T_in = 38℃, solar radiation S = strong.

[0056] The control unit determines that "pre-cooling mode" needs to be activated: the front deflector is fully opened; high-speed airflow enters the air duct splitter through the deflector, the semiconductor cooling chip is activated (power adjusted according to S), and the airflow is pre-cooled to 28°C before being sent into the vehicle. The interior temperature gradually drops to 35°C, and the control unit reduces the heat exchanger power to maintain a comfortable temperature.

[0057] This invention provides a control system for dynamically adjusting the temperature inside a vehicle using external airflow, comprising: The vehicle includes a front fairing, connecting pipes, a temperature control module, an external temperature sensor, an internal temperature sensor, and a controller; wherein the temperature control module, the external temperature sensor, and the internal temperature sensor are all connected to the controller. The front fairing is used to input airflow from the external environment of the vehicle into the connecting pipe; The external temperature sensor is used to monitor the ambient temperature outside the vehicle. The in-vehicle temperature sensor is used to monitor the ambient temperature inside the vehicle. The controller is used to adjust the vehicle's temperature control mode based on the vehicle's external ambient temperature, the vehicle's interior ambient temperature, and the vehicle's speed; wherein, the vehicle's temperature control mode is associated with the operating status of the front fairing and the operating status of the temperature regulation module; the front fairing is used to increase the air pressure difference between the external airflow and the internal environment of the vehicle; and The vehicle interior temperature is dynamically adjusted based on the vehicle's current temperature control mode.

[0058] In this exemplary embodiment, the front fairing may be located behind the front bumper or grille, and has a built-in openable and closable air deflector (electrically controlled) that opens at high speeds to increase airflow capture and closes at low speeds to reduce wind resistance.

[0059] In this exemplary embodiment, the temperature regulation module may include a miniature heat exchanger (such as a semiconductor cooling chip or a small liquid cooling cycle) integrated in the air duct to pre-cool when the outside air temperature is unsuitable (such as high-temperature airflow in summer) or preheat when the airflow is low-temperature in winter.

[0060] In this exemplary embodiment, the sensor group may include an outside temperature sensor, an inside temperature sensor, a vehicle speed sensor, a humidity sensor, and a solar radiation sensor (detecting sunlight intensity).

[0061] In this exemplary embodiment, the controller can adjust the opening of the deflector and the temperature regulation module and other actuators according to the vehicle's speed and ventilation path.

[0062] In this exemplary embodiment, the connecting pipe can connect the baffle plate and the air conditioning inlet.

[0063] This application introduces outside airflow into the vehicle through a front fairing and uses the temperature difference between the inside and outside of the vehicle to regulate the interior temperature in certain environments. This reduces the use of the air conditioner and blower in certain environments, thereby reducing the vehicle's reliance on air conditioning for temperature control and the energy consumption caused by air conditioning reliance.
