These drawings and textual descriptions are not intended to limit the scope of the present disclosure in any way, but rather to illustrate the concepts of the present disclosure to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0037] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings 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.

[0038] Before introducing the embodiments of the present application, the application background of the embodiments of the present application is first explained:

[0039] In the automotive industry, seat comfort has become a crucial factor in enhancing the overall driving experience. Vehicles equipped with seat ventilation and heating technology can significantly improve the comfort of drivers and passengers in all seasons, providing a more intimate and user-friendly ride experience.

[0040] A vehicle equipped with heated and ventilated seats can provide a more comfortable driving experience. Especially during hot summer months, the seat ventilation function effectively dissipates heat and cools the seat surface. By drawing outside air into the seat surface, it quickly dissipates heat, removing sweat and moisture from the body, keeping the driver's back and hips cool and reducing fatigue. In winter, the seat heating function uses electric heating elements to quickly raise the seat surface temperature, effectively alleviating the discomfort caused by low seat temperatures. Furthermore, the heated seats soothe muscles, reduce tension, and enhance driving comfort and concentration.

[0041] However, existing seats use a fan system for ventilation and cooling, and an electric heating wire system for heating the seats. The fan system and the electric heating wire system are two independent systems. The installation costs of the two systems are high and the economic applicability is not high.

[0042] In response to the technical problems existing in the prior art, the inventors of this application have come up with the following idea: to address the problem of low economic applicability of the ventilation and heating devices in the prior art that use two independent systems for heating and cooling. A thermoelectric cooler is a device based on semiconductor materials that has the Peltier effect (that is, when current passes through different contact surfaces of a semiconductor material, the contact surfaces absorb or release heat, causing one side to become cold and the other side to become hot). Therefore, the thermoelectric cooler can heat and cool at the same time. Therefore, the heating surface of the thermoelectric cooler can be connected to the hot-end radiator, and the cooling surface of the thermoelectric cooler can be connected to the cold-end radiator. The ventilation and heating device constructed based on this can be used for both ventilation (that is, cooling) and heating. Specifically, when in use, the air sucked in by the centrifugal fan is transmitted to the heating surface of the hot-end radiator, and warm air is output; when the air sucked in by the centrifugal fan is transmitted to the cooling surface of the hot-end radiator, cold air is output, thereby improving the performance of the ventilation and heating device.

[0043] The technical solution of the present application is described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0044] Figure 1 Schematic diagram of the structure of the ventilation and heating device provided in the embodiment of the present application Figure 1 ,like Figure 1 As shown, the ventilation and heating device may include: a centrifugal fan 10, a thermoelectric cooler 20, a hot end radiator 30, and a cold end radiator 40;

[0045] Optionally, the centrifugal fan 10 is connected to the air inlet of the hot-end radiator 30 and the air inlet of the cold-end radiator 40 respectively;

[0046] In this implementation, the centrifugal fan 10 is arranged at the front end of the hot end radiator 30 and the cold end radiator 40. The centrifugal fan 10 is used to inhale external air and transport the external air to the air inlet of the hot end radiator 30 and the air inlet of the cold end radiator 40 respectively.

[0047] in, Figure 1 The portion enclosed by the dotted dashed line between the centrifugal fan 10 and the hot-end radiator 30 and the cold-end radiator 40 is the fan's air outlet 140 (also known as the air inlet for the hot-end radiator 30 and the cold-end radiator 40). The centrifugal fan 10 delivers the air it draws in to the hot-end radiator 30 and the cold-end radiator 40 through the air outlet 140. The centrifugal fan 10 can be a single-suction centrifugal fan, a double-suction centrifugal fan, a direct-drive centrifugal fan, a belt-driven centrifugal fan, or other types. A thermoelectric cooler utilizes the Peltier effect of semiconductors, with the cold side generating cooling and the hot side releasing heat.

[0048] In one possible implementation, the centrifugal fan 10 draws in air, and the rotation of the fan impeller accelerates the air to generate a higher air flow velocity. The accelerated air is guided to the hot-end radiator 30 and the cold-end radiator 40 through the air outlet 140 of the centrifugal fan 10 .

[0049] Optionally, the hot surface 201 of the thermoelectric cooler 20 is connected to the hot-end radiator 30 , and the cold surface 202 of the thermoelectric cooler 20 is connected to the cold-end radiator 40 .

[0050] In this implementation, the hot surface 201 of the thermoelectric cooler 20 is connected to the hot end radiator 30, and the hot surface 201 of the thermoelectric cooler 20 can process the air circulating in the hot end radiator 30. The cold surface 202 of the thermoelectric cooler 20 is connected to the cold end radiator 40, and the cold surface 202 of the thermoelectric cooler 20 can process the air circulating in the cold end radiator 40.

[0051] In one possible implementation, the air inhaled from the outside by the centrifugal fan 10 flows into the hot-end radiator 30 and the cold-end radiator 40 respectively, the hot surface 201 of the thermoelectric cooler 20 will be heated, and the cold surface 202 of the thermoelectric cooler 20 will be cooled. Therefore, the temperature of the air circulating in the hot-end radiator 30 and the cold-end radiator 40 can be adjusted accordingly.

[0052] Further, Figure 2 Schematic diagram of the structure of the ventilation and heating device provided in the embodiment of the present application Figure 2 ,like Figure 2 As shown, the ventilation and heating device further includes: a first thermally conductive gel layer 50;

[0053] The first thermally conductive gel layer 50 is connected to the hot surface 201 of the thermoelectric cooler 20 and the first heat dissipation substrate 301 at the bottom of the hot end heat sink 30 , respectively.

[0054] In this implementation, the bottom surface of the first thermally conductive gel layer 50 is connected to the hot surface 201 of the thermoelectric cooler 20 , and the top surface of the first thermally conductive gel layer 50 is connected to the first heat dissipation substrate 301 at the bottom of the hot end heat sink 30 .

[0055] The thermally conductive gel is typically composed of a filler with high thermal conductivity and a suitable matrix material. The first thermally conductive gel layer 50 is evenly applied to a predetermined thickness between the thermoelectric cooler 20 and the hot-end heat sink 30. The first thermally conductive gel layer 50 serves as the thermal contact material between the hot surface 201 of the thermoelectric cooler 20 and the hot-end heat sink 30. Its primary function is to reduce the contact thermal resistance between the thermoelectric cooler 20 and the hot-end heat sink 30, thereby improving heat exchange efficiency and ensuring heat transfer from the hot surface 201 of the thermoelectric cooler 20 to the hot-end heat sink 30. This effectively dissipates heat and warms the air flowing through the hot-end heat sink 30.

[0056] In one possible implementation, the thermally conductive gel may be a mixture of a metal oxide (eg, aluminum oxide (Al 2 O 3 )) and a binder (eg, silica gel).

[0057] Furthermore, the ventilation and heating device further comprises: a second thermally conductive gel layer 60;

[0058] The second thermally conductive gel layer 60 is connected to the cold surface 202 of the thermoelectric cooler 20 and the second heat dissipation substrate 401 on the upper portion of the cold end heat sink 40 , respectively.

[0059] In this implementation, the bottom surface of the second thermally conductive gel layer 60 is connected to the second heat dissipation substrate 401 on the upper portion of the cold end heat sink 40 , and the top surface of the second thermally conductive gel layer 60 is connected to the cold surface 202 of the thermoelectric cooler 20 .

[0060] The second thermally conductive gel layer 60 is a thermally conductive gel evenly applied to a predetermined thickness between the thermoelectric cooler 20 and the cold end heat sink 40. The second thermally conductive gel layer 60 serves as the contact material between the cold surface 202 of the thermoelectric cooler 20 and the cold end heat sink 40. Its primary function is to transfer heat generated by the cold surface 202 of the thermoelectric cooler 20 to the cold end heat sink 40. In other words, the thermally conductive gel acts as a bridge for heat transfer between the thermoelectric cooler 20 and the cold end heat sink 40, filling the tiny gap between them and ensuring efficient heat transfer without wasting, thereby cooling the air flowing through the cold end heat sink 40.

[0061] Specifically, the higher the thermal conductivity of the thermally conductive gel, the more efficient the heat transfer. The viscosity of the thermally conductive gel should be moderate, ensuring sufficient adhesion to prevent the gel layer from flowing or moving, while also ensuring that it can fill the gap between the cold surface 202 of the thermoelectric cooler 20 and the second heat dissipation substrate 401 on the upper portion of the cold end heat sink 40, ensuring good contact. The thermally conductive gel may be affected by mechanical stress, thermal expansion, or contraction during long-term use. Therefore, its mechanical properties must be sufficiently stable to ensure that it does not degrade over time.

[0062] In one possible implementation, the thermally conductive gel may be a silicon oxide (SiO2) and polyurethane (PU) based adhesive.

[0063] Further, Figure 3 Schematic diagram of the structure of the ventilation and heating device provided in the embodiment of the present application Figure 3 ,like Figure 3 As shown, the ventilation and heating device further includes: a first air guide unit 70 and a second air guide unit 80;

[0064] Optionally, the first air guide unit 70 is provided between the centrifugal fan 10 and the air inlet 305 of the hot end radiator 30;

[0065] In this implementation, the first air guide unit 70 is arranged between the centrifugal fan 10 and the air inlet 305 of the hot end radiator 30, which can guide the flow direction of the external air sucked in by the centrifugal fan 10 and ensure that the air can flow into the hot end radiator 30 evenly.

[0066] Among them, the first guide unit 70 must not only conform to the airflow path (that is, the bending angle of the first guide unit 70 and the air outlet angle of the centrifugal fan 10 must be designed to match), which can effectively reduce the system resistance and increase the actual air volume of the fan, ensuring that the airflow can be accurately delivered to the hot end heat sink 30, but also must be made of lightweight and high-strength materials (such as high-strength plastics or light metal alloys), and at the same time have certain heat resistance and corrosion resistance.

[0067] In a possible implementation, the first air guiding unit 70 may be made of polypropylene (PP).

[0068] It is worth noting that the design of the first guide unit 70 may not be the same as Figure 3 It is sufficient as long as the air sucked by the centrifugal fan 10 can be quickly and efficiently transported to the hot end radiator 30.

[0069] Optionally, the second air guide unit 80 is disposed between the centrifugal fan 10 and the air inlet 405 of the cold end radiator 40 .

[0070] In this implementation, the second air guide unit 80 is arranged between the centrifugal fan 10 and the air inlet 405 of the cold end heat sink 40, which can guide the flow direction of the external air sucked in by the centrifugal fan 10 and ensure that the air can flow into the cold end heat sink 40 evenly.

[0071] It is worth noting that the design of the second guide unit 80 may not be the same as Figure 3 It is sufficient as long as the air sucked by the centrifugal fan 10 can be quickly and efficiently transported to the cold end radiator 40.

[0072] The ventilation and heating device provided in an embodiment of the present application may include a centrifugal fan, a thermoelectric cooler, a hot-end radiator, and a cold-end radiator. The centrifugal fan is connected to the air inlet of the hot-end radiator and the air inlet of the cold-end radiator, respectively. The hot surface of the thermoelectric cooler is connected to the hot-end radiator, and the cold surface of the thermoelectric cooler is connected to the cold-end radiator. In this technical solution, external air is drawn into the device via the centrifugal fan and then delivered to the hot-end radiator and the cold-end radiator for heating or cooling, respectively. This significantly improves the heat exchange efficiency between the external air and the hot-end radiator and the cold-end radiator, thereby enabling efficient and stable output of warm and cold air.

[0073] Based on the above embodiments, Figure 4 Schematic diagram of the structure of the ventilation and heating device provided in the embodiment of the present application Figure 4 ,like Figure 4 As shown, the ventilation and heating device further includes: a third air guide unit 90 and a fourth air guide unit 100;

[0074] Optionally, the third air guide unit 90 is provided at the air outlet of the hot end radiator 30;

[0075] In this implementation, the third air guide unit 90 is disposed at the air outlet 306 of the hot end radiator 30 , and the third air guide unit 90 can input the air processed by the hot end radiator 30 to the outside of the seat.

[0076] In one possible implementation, in a hot environment, the seat's ventilation mode is activated to cool the seat. The current direction of the thermoelectric cooler 20 is set to forward. In this case, the hot surface 201 of the thermoelectric cooler 20 generates heat, while the cold surface 202 generates cooling. However, the hot end heat sink 30 is connected to the hot surface 201 via a thermally conductive gel layer, so the air flowing through the hot end heat sink 30 is heated, generating hot air. However, the seat does not need hot air in ventilation mode, so the hot air generated by the hot end heat sink 30 needs to be transported to the outside of the seat through the third air guide unit 90 to interact with the air inside the vehicle.

[0077] In one possible implementation, in a cold environment, the heating mode of the seat is turned on. In this mode, the seat needs to be heated. A controllable power supply can be used to change the current direction of the thermoelectric cooler 20 (from positive flow to negative flow). The thermoelectric cooler 20 will change the hot surface 201 of the thermoelectric cooler 20 from heating to cooling, and the cold surface 202 of the thermoelectric cooler 20 from cooling to heating as the current direction changes. The hot end radiator 30 is connected to the hot surface 201 of the thermoelectric cooler 20 through a thermal conductive gel layer, but the hot surface 201 changes from heating to cooling in this mode, so the air circulating in the hot end radiator 30 will be cooled to generate cold air, but the seat does not need cold air in the heating mode, so the cold air generated by the hot end radiator 30 needs to be transported to the outside of the seat through the third air guide unit 90 to interact with the air inside the car.

[0078] Optionally, the fourth air guiding unit 100 is disposed at the air outlet 406 of the cold end radiator 40 .

[0079] In this implementation, the fourth air guide unit 100 is disposed at the air outlet 406 of the cold end radiator 40 , and the fourth air guide unit 100 delivers the air processed by the cold end radiator 40 to the back and buttocks of the seat.

[0080] In one possible implementation, during a hot summer day, the seat's ventilation mode is enabled. In this mode, the seat needs to be cooled. The current flowing through the thermoelectric cooler 20 is in the forward direction. In this case, the hot surface 201 of the thermoelectric cooler 20 generates heat, while the cold surface 202 generates cooling. However, the cold end radiator 40 is connected to the cold surface 202, so the air flowing through the cold end radiator 40 is cooled, generating cool air. Because the seat requires cool air in ventilation mode, the cool air generated by the cold end radiator 40 needs to be delivered to the seat's back and buttocks via the fourth air guide unit 100 to cool the seat.

[0081] In one possible implementation, in the cold winter, the heating mode of the seat is turned on. In this mode, the seat needs to be heated. A controllable power supply can be used to change the current direction of the thermoelectric cooler 20 (from positive flow to negative flow). The thermoelectric cooler 20 will change the hot surface 201 of the thermoelectric cooler 20 from heating to cooling, and the cold surface 202 of the thermoelectric cooler 20 from cooling to heating as the current direction changes. The cold end radiator 40 is connected to the cold surface 202 of the thermoelectric cooler 20, but the cold surface 202 changes from cooling to heating in this mode. Therefore, the air circulating in the cold end radiator 40 will be heated to generate hot air. Because the seat needs hot air in the heating mode, the hot air generated by the cold end radiator 40 needs to be transported to the back and buttocks of the seat through the fourth air guide unit 100 to heat the seat.

[0082] Furthermore, the ventilation and heating device further includes: a housing 110;

[0083] Optionally, the housing 110 encloses the centrifugal fan 10 , the thermoelectric cooler 20 , the hot-end radiator 30 , the cold-end radiator 40 , the first air guide unit 70 , the second air guide unit 80 , the third air guide unit 90 and the fourth air guide unit 100 .

[0084] In this implementation, the housing 110 carries the centrifugal fan 10, the thermoelectric cooler 20, the hot-end heat sink 30, the cold-end heat sink 40, the first air guide unit 70, the second air guide unit 80, the third air guide unit 90, and the fourth air guide unit 100. This provides physical protection for the internal components (all components of the ventilation and heating device described above) to prevent damage to the internal components from the external environment.

[0085] The outer shape of the housing 110 can be adjusted according to the structure and arrangement of the internal components. The housing 110 is usually made of plastic, composite material, etc.

[0086] In a possible implementation, the material of the housing 110 is acrylonitrile butadiene styrene copolymer (ABS).

[0087] Furthermore, the ventilation and heating device further comprises: a power supply 130;

[0088] Optionally, the positive electrode of the power supply 130 is connected to the first end of the thermoelectric cooler 20;

[0089] In this implementation, the positive electrode 120 of the power supply 130 is connected to the first end of the thermoelectric cooler 20 (ie Figure 4 The hot surface 201 of the thermoelectric cooler 20 is connected to the hot surface 201 of the thermoelectric cooler 20. When the current flows from the positive electrode to the negative electrode, the hot surface 201 of the thermoelectric cooler 20 releases heat, causing the temperature of the hot surface to rise.

[0090] Optionally, the negative electrode of the power supply 130 is connected to the second end of the thermoelectric cooler 20 .

[0091] In this implementation, the negative electrode 130 of the power supply 130 is connected to the second end of the thermoelectric cooler 20 (ie Figure 4 When the current flows from the positive electrode to the negative electrode, the hot surface 201 of the thermoelectric cooler 20 releases heat while the cold surface 202 absorbs heat, causing its temperature to drop, thereby achieving a cooling effect.

[0092] In one possible implementation, the power supply 130 may be a controllable power supply capable of controlling the direction of current flow. When the vehicle computer detects that the seat heating mode is activated, it issues a command to the controllable power supply to change the direction of the current flow. The controllable power supply then changes the positive current flow to a negative current flow (i.e., the current flows from the negative electrode to the positive electrode). This causes the hot surface 201 of the thermoelectric cooler 20 to switch from heating to cooling, and the cold surface 202 of the thermoelectric cooler 20 to switch from cooling to heating.

[0093] The ventilation and heating device provided in an embodiment of the present application further includes: a third air guide unit and a fourth air guide unit, wherein the third air guide unit is disposed at the air outlet of the hot-end radiator, and the fourth air guide unit is disposed at the air outlet of the cold-end radiator. In this technical solution, the air processed by the hot-end radiator and the air processed by the cold-end radiator are respectively delivered to the outside of the seat or to the back and buttocks of the seat through the two air guide units. This achieves the technical effect of achieving precise heating and cooling functions in both ventilation mode and heating mode, maintaining a comfortable riding experience in the seat.

[0094] Based on the above embodiments, Figure 5 The schematic diagram of the structure of the hot end radiator and the cold end radiator provided in the embodiment of the present application is as follows: Figure 5 As shown, the hot end heat sink 30 includes: two first heat dissipation substrates 301 respectively arranged one above the other, and first heat dissipation fins 302 are arranged in the two first heat dissipation substrates 301 .

[0095] In this implementation, the hot end heat sink 30 includes a first heat dissipation substrate 301 provided in an upper and lower portion, and at least two first heat dissipation fins 302 are provided in the two first heat dissipation substrates 301 .

[0096] The spacing between two adjacent heat sink fins 302 forms an independent heat exchange air duct, facilitating air circulation within the hot-end heat sink 30. External air drawn in by the centrifugal fan 10 circulates through at least two heat sink fins 302. This design allows air to flow freely between the surface of the first heat sink substrate 301 and the at least two first heat sink fins 302, enhancing heat exchange.

[0097] In a possible implementation, one hot-end heat sink 30 may use seven heat dissipation fins 302 .

[0098] Furthermore, the cold end heat sink 40 includes: two second heat dissipation substrates 401 respectively arranged one above the other, and second heat dissipation fins 402 are arranged in the two second heat dissipation substrates 401 .

[0099] In this implementation, the cold end heat sink 40 includes a second heat dissipation substrate 401 provided in an upper and lower portion, and at least two second heat dissipation fins 402 are provided between the two second heat dissipation substrates 401 .

[0100] In one possible implementation, the air inhaled by the centrifugal fan 10 circulates in at least two second heat sink fins 402 , and the second heat sink substrate 401 transfers heat from the thermoelectric cooler 20 to the air circulating in the second heat sink fins 402 , and the cooled air flows out of the second heat sink fins 402 .

[0101] In a possible implementation, one cold-end heat sink 40 may use seven heat dissipation fins 402 .

[0102] The ventilation and heating device provided in an embodiment of the present application has a hot-end radiator comprising two first heat-dissipating substrates disposed one above the other, each with first heat-dissipating fins disposed therein, and a cold-end radiator comprising two second heat-dissipating substrates disposed one above the other, each with second heat-dissipating fins disposed therein. In this technical solution, air enters the air duct formed by at least two heat-dissipating fins through the heat-dissipating substrates. The circulating air is heated or cooled by the hot-end and cold-end radiators before exiting through the heat-dissipating fins. This achieves the technical effects of optimizing air flow, improving heat dissipation efficiency, and achieving more stable, balanced, and efficient thermal management in complex working environments.

[0103] Based on the above embodiments, Figure 6 This is a schematic diagram of the structure of the ventilation and heating seat provided in the embodiment of the present application, as shown in FIG. Figure 6As shown, the ventilated and heated seat 150 includes: a ventilated and heated device 1501 and a structural component 1502 that wraps and fixes the ventilated and heated device.

[0104] The functions and effects of the components in the ventilated and heated seat 150 are as shown in the above embodiments and will not be repeated here.

[0105] In one possible implementation, Figure 7 This is a flow chart of the function of using the ventilation and heating seat provided in the embodiment of the present application. Figure 7 As shown, the functional use process of the ventilated and heated seat 150 is specifically introduced:

[0106] Step 1: The vehicle computer obtains the current date, weather and other information.

[0107] In this step, the vehicle is started, and the host (i.e., controller) in the vehicle obtains information such as the current date and weather and analyzes it.

[0108] Step 2: The camera inside the car identifies whether there are people in the car.

[0109] In this step, if it is recognized that there is a person on board, step 3 is executed.

[0110] Step 3: Use voice interaction to activate the seat function mode.

[0125] Step 10: Reduce the duty cycle of the thermoelectric cooler 20.

[0126] In this step, the vehicle computer reduces the duty cycle of the thermoelectric cooler 20 , thereby reducing the cooling effect of the thermoelectric cooler 20 .

[0127] After completing this step, proceed to step 12.

[0128] Step 12: Reduce the duty cycle of the centrifugal fan 10.

[0129] In this step, the duty cycle of the centrifugal fan 10 decreases accordingly as the duty cycle of the thermoelectric cooler 20 decreases.

If the temperature sensor determines that the temperature is not between 25°C and 27°C, step 10 is executed. The temperature sensor feeds back the detected temperature data to the vehicle computer.

[0133] Step 16: The duty cycles of the thermoelectric cooler 20 and the centrifugal fan 10 remain unchanged.

[0134] In this step, the temperature is maintained between 25° C. and 27° C., and the duty cycles of the thermoelectric cooler 20 and the centrifugal fan 10 are maintained unchanged.

[0135] Step 11: Increase the duty cycle of the thermoelectric cooler 20.

[0136] In this step, the vehicle computer increases the duty cycle of the thermoelectric cooler 20 to improve the heating effect of the thermoelectric cooler 20 .

[0137] After completing this step, proceed to step 13.

[0138] Step 13: Increase the duty cycle of the centrifugal fan 10.

[0139] In this step, the duty cycle of the centrifugal fan 10 increases accordingly as the duty cycle of the thermoelectric cooler 20 increases.

[0140] After completing this step, proceed to step 15.

[0141] Step 15: Determine whether the temperature is between 25℃ and 27℃.

[0142] In this step, the temperature sensor determines whether the temperature is between 25°C and 27°C. If so, step 17 is executed. If the temperature sensor determines that the temperature is not between 25°C and 27°C, step 11 is executed and the temperature sensor feeds back the detected temperature data to the vehicle computer.

[0143] Step 17: The duty cycles of the thermoelectric cooler 20 and the centrifugal fan 10 remain unchanged.

[0144] Step 18: Increase the duty cycle of the thermoelectric cooler 20.

[0145] In this step, the vehicle computer increases the duty cycle of the thermoelectric cooler 20 to improve the cooling effect of the thermoelectric cooler 20 .

[0146] After completing this step, proceed to step 20.

[0147] Step 20: Increase the duty cycle of the centrifugal fan 10.

[0148] After completing this step, proceed to step 22.

[0149] Step 22: Determine whether the temperature is between 25°C and 27°C.

[0150] In this step, the temperature sensor determines whether the temperature is between 25°C and 27°C. If so, step 24 is executed. If the temperature sensor determines that the temperature is not between 25°C and 27°C, step 18 is executed. The temperature sensor feeds back the detected temperature data to the vehicle computer.

[0151] Step 24: The duty cycles of the thermoelectric cooler 20 and the centrifugal fan 10 remain unchanged.

[0152] Step 19: Reduce the duty cycle of the thermoelectric cooler 20.

[0153] In this step, the vehicle computer reduces the duty cycle of the thermoelectric cooler 20 to reduce the heating effect of the thermoelectric cooler 20 .

[0154] After completing this step, proceed to step 21.

[0155] Step 21: Reduce the duty cycle of the centrifugal fan 10.

[0156] After completing this step, proceed to step 23.

[0157] Step 23: Determine whether the temperature is between 25°C and 27°C.

[0158] In this step, the temperature sensor determines whether the temperature is between 25°C and 27°C. If so, step 24 is executed. If the temperature sensor determines that the temperature is not between 25°C and 27°C, step 19 is executed. The temperature sensor feeds back the detected temperature data to the vehicle computer.

[0159] It's worth noting that if a user uses the vehicle multiple times within the same day, the vehicle's memory function will directly activate the corresponding seat function based on the user's previous use, avoiding repeated voice interaction and providing greater intelligence and convenience. Heating mode is achieved by simply changing the current direction of the thermoelectric cooler. Its overall adjustment logic is opposite to that of ventilation mode. This intelligent adjustment can effectively improve the user experience and reduce battery energy loss, thereby increasing the vehicle's range.
