Description
Technical Field
[0001] This application relates to the field of vehicle technology, and more particularly to an air conditioning and heating system and a vehicle. Background Technology
[0002] As an essential feature of vehicles, the air conditioning and heating system provides functions such as heating, defrosting, and regulating temperature and humidity. Traditionally, the heat source for the air conditioning and heating system in vehicles comes primarily from the engine coolant. By introducing the relatively hot engine coolant into the heater core, the system provides heating for the vehicle interior.
[0003] To regulate the temperature inside the vehicle's cabin, existing air conditioning and heating systems typically include hot and cold air dampers and motors. The motor drives the dampers to adjust the airflow through the heating element, thereby regulating the temperature of the warm air. However, the inclusion of hot and cold air dampers and motors increases the size of the air conditioning and heating system, thus increasing the space requirements of the cabin and potentially limiting the creative design space within the cabin. Utility Model Content

[0035] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0036] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.
[0037] The air conditioning and heating system and vehicle provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0038] Reference Figures 1 to 7 As shown, some embodiments of this application provide an air conditioning and heating system, including an inner air conditioning portion 1 and an outer air conditioning portion 2. The inner air conditioning portion 1 can be arranged inside the dashboard of the vehicle's passenger compartment, and the outer air conditioning portion 2 can be arranged in front of the cooling fan in the vehicle's front engine compartment.
[0039] Among them, reference Figure 2 and Figure 3 As shown, the inner part 1 of the air conditioner includes a heating core 11, a connecting pipe 12, and a system liquid outlet pipe 13; (Refer to...) Figure 2 and Figure 5 As shown, the outer part 2 of the air conditioner includes an outer heat exchanger 21, a system liquid inlet pipe 22, a movable plate, and an adjustment device.
[0040] Reference Figure 2 , Figure 3 and Figure 5 As shown, the outer heat exchanger 21 has an inlet 211 and an outlet 212. The system inlet pipe 22 is connected to the inlet 211, and the outlet 212 is connected to the inlet of the heater core 11 through a connecting pipe 12. The outlet of the heater core 11 is connected to the system outlet pipe 13. Thus, the system inlet pipe 22, the outer heat exchanger 21, the connecting pipe 12, the heater core 11, and the system outlet pipe 13 are sequentially connected to form a heat exchange flow path. This allows the stored liquid entering through the system inlet pipe 22 to exchange heat with the outer heat exchanger 21 before flowing into the heater core 11. In other words, the outer heat exchanger 21, located on the outer side of the air conditioning unit 2, pre-exchanges heat between the stored liquid and the outside environment to regulate the temperature of the stored liquid before it flows into the heater core 11.
[0041] It should be noted that the source of the heat storage fluid can be the engine coolant. During engine operation, heat is generated, and the coolant can exchange heat with the engine to cool it down. The coolant after heat exchange forms a higher-temperature heat storage fluid. The air conditioning and heating system can utilize the heat generated by the engine coolant through heat exchange to exchange heat with the heating core 11 of the air conditioning unit 1, thereby providing heating for the vehicle interior. Of course, the source of the heat storage fluid is not limited to engine coolant; for pure electric vehicles, the heat storage fluid can be a liquid heated by a heater.
[0042] Reference Figure 6 and Figure 7As shown, the movable plate is located inside the outer heat exchanger 21, dividing the internal flow space of the outer heat exchanger 21 into a heat exchange space and a regulating space, as shown in the figure. Figure 2 and Figure 4 As shown, the regulating device is used to provide force to the movable plate to drive the movable plate to move, so as to regulate the heat exchange area of the heat storage liquid flowing through the heat exchange space of the outer heat exchanger 21, and thereby regulate the temperature of the heat storage liquid flowing into the warm air core 11.
[0043] With the above configuration, a movable plate is provided inside the outer heat exchanger 21. The movable plate can move within the internal flow space of the outer heat exchanger 21 to divide the internal flow space of the outer heat exchanger 21 into a heat exchange space (for the flow of heat storage liquid) and an adjustment space. The adjustment device provides force to the movable plate so that the movable plate can move within the internal flow space of the outer heat exchanger 21. The movement of the movable plate adjusts the heat exchange area of the heat storage liquid flowing through the heat exchange space in the outer heat exchanger 21, thereby adjusting the amount of heat exchanged between the heat storage liquid entering the outer heat exchanger 21 and the outside. In this way, the temperature of the heat storage liquid flowing into the warm air core 11 through the outlet 212 of the outer heat exchanger 21 is controlled, thereby achieving the purpose of adjusting the outlet air temperature of the air conditioning and heating system. This enables the air conditioning and heating system to achieve temperature control without the need for hot and cold air dampers, thereby reducing the number of components in the inner part 1 of the air conditioning system, reducing the space requirements of the air conditioning and heating system in the cockpit, and increasing the space for design and creativity in the cockpit.
[0044] It should be understood that, in specific implementation, the heat exchange space and the regulating space can be arranged vertically, with the heat exchange space located above the regulating space. Correspondingly, the inlet 211 and outlet 212 of the outer heat exchanger 21 can both be located at the upper part of the outer heat exchanger 21 and communicate with the heat exchange space located above the movable plate within the outer heat exchanger 21. This allows the stored heat liquid to enter the outer heat exchanger 21, flow within its heat exchange space, and fully exchange heat with the outside environment during the flow. After heat exchange, the stored heat liquid flows out of the outer heat exchanger 21 through the outlet 212 and into the warm air core 11. The movable plate can move vertically within the internal flow space of the outer heat exchanger 21 to adjust the heat exchange area of the stored heat liquid flowing through the heat exchange space of the outer heat exchanger. The larger the heat exchange area of the heat exchange space, the more heat the stored liquid entering the outer heat exchanger 21 exchanges with the outside environment, resulting in a lower temperature of the stored liquid flowing into the heater core 11 and a lower temperature blown into the cockpit through the heater core 11. Conversely, the smaller the heat exchange area of the heat exchange space, the less heat the stored liquid entering the outer heat exchanger 21 exchanges with the outside environment, resulting in a higher temperature of the stored liquid flowing into the heater core 11 and a higher temperature blown into the cockpit through the heater core 11. Thus, by adjusting the height of the movable plate within the internal flow space of the outer heat exchanger 21, precise control of the temperature of the stored liquid entering the heater core 11 can be achieved.
[0045] Of course, in specific implementation, the heat exchange space and the regulating space are not limited to being arranged vertically, but can also be arranged horizontally as needed, that is, the heat exchange space is located on one side of the regulating space. Correspondingly, the liquid inlet 211 and liquid outlet 212 of the outer heat exchanger 21 can both be located on the same side of the movable plate, and both are located on the side of the outer heat exchanger 21 away from the regulating space, and both are connected to the heat exchange space. Specifically, the liquid inlet 211 of the outer heat exchanger 21 can be located at the lower part of the outer heat exchanger 21, and the liquid outlet 212 can be located at the upper part of the outer heat exchanger 21, so that after the heat storage liquid enters the outer heat exchanger 21 through the liquid inlet 211, it flows in the heat exchange space of the outer heat exchanger 21 and fully exchanges heat with the outside during the flow process. After heat exchange, the heat storage liquid flows out of the outer heat exchanger 21 through the liquid outlet 212 and flows into the warm air core 11. The movable plate can reciprocate horizontally within the internal flow space of the outer heat exchanger 21 to adjust the heat exchange area of the heat storage liquid flowing through the heat exchange space of the outer heat exchanger 21 by the horizontal reciprocating motion (e.g., left and right movement) of the movable plate.
[0046] In practical implementation, when a user requests to set the air conditioning temperature, the air conditioning controller can correspondingly set the target temperature requirement value of the heating core 11 based on the user's set air conditioning temperature. A temperature sensor 15 can be installed in the internal circulation space of the heating core 11 to detect the temperature of the heat storage liquid inside the heating core 11. By comparing the target liquid temperature with the detected actual liquid temperature, the controller adjusts the position of the movable plate inside the outer heat exchanger 21 to adjust the heat exchange area of the heat exchange space of the outer heat exchanger 21. This achieves the purpose of rapid and accurate temperature control of the heat storage liquid entering the heating core 11, so that the air conditioning heating system can quickly complete temperature control according to user needs.
[0047] It should be noted that the temperature of the heat storage liquid in the system inlet pipe 22 of the air conditioning heating system is generally about 85°C. The target liquid temperature of the heating core 11 can be pre-calibrated by combining the detection parameters such as the height position of the movable plate in the outer heat exchanger 21 (of course, other detection parameters can also be combined), such as how a certain target liquid temperature is associated with a certain height position, so that the air conditioning heating system can quickly complete temperature regulation.
[0048] In specific implementations, the movable plate and adjustment device can have various structural designs. For example, refer to... Figure 6 and Figure 7 As shown, the movable plate can be a float 23, and the adjusting device can be a liquid level adjusting device 24. The liquid level adjusting device 24 fills the adjusting space of the outer heat exchanger 21 with liquid and controls the amount of liquid filling, causing the float 23 to float up and down under the action of liquid buoyancy and its own weight. Exemplarily, the adjusting device can also be an electric actuator, which pushes or pulls the movable plate up and down, causing the movable plate to move up and down under the action of the electric actuator; or, it can push or pull the movable plate horizontally reciprocating, causing the movable plate to move horizontally reciprocating under the action of the electric actuator. Exemplarily, the adjusting device can also be a cylinder, which pushes or pulls the movable plate up and down through the cylinder rod, causing the movable plate to move up and down under the action of the cylinder; or, it can push or pull the movable plate horizontally reciprocating, causing the movable plate to move horizontally reciprocating under the action of the cylinder. As long as it is possible to provide force to the movable plate through the adjustment device, so that the movable plate can reciprocate within the internal flow space of the outer heat exchanger 21, thereby adjusting the heat exchange area of the heat exchange space within the outer heat exchanger 21.
[0049] In some embodiments, refer to Figure 2 , Figures 5 to 7As shown, the heat exchange space is located above the regulating space. The movable plate is a float plate 23, which floats inside the outer heat exchanger 21 to divide the internal flow space of the outer heat exchanger 21 into a heat exchange space above the float plate 23 and a regulating space below the float plate 23. The regulating device is a liquid level regulating device 24. The lower part of the outer heat exchanger 21 is provided with a liquid level regulating port 213. The liquid level regulating device 24 is connected to the liquid level regulating port 213 to fill the regulating space of the outer heat exchanger 21 with liquid and control the amount of liquid filling so that the float plate 23 floats up and down under the action of liquid buoyancy and its own weight.
[0050] In practical implementation, the liquid injected into the regulating space of the outer heat exchanger 21 through the liquid level regulating device 24 can be water or other liquids. By controlling the amount of liquid injected, the height at which the float 23 floats upward under the action of liquid buoyancy is controlled, thereby achieving precise control of the heat exchange area of the heat exchange space above the float 23 within the outer heat exchanger 21. The structure of using the float 23 in conjunction with the liquid level regulating device 24 is simple, low-cost, and easy to implement.
[0051] In some embodiments, refer to Figure 2 and Figure 5 As shown, the liquid level regulating device 24 includes a storage tank 241, a connecting pipe 242, a water pump 243, and a shut-off valve 244. The storage tank 241 stores liquid and is connected to a liquid level regulating port 213 via the connecting pipe 242. The water pump 243 and shut-off valve 244 are mounted on the connecting pipe 242. With this configuration, when the shut-off valve 244 is open, the water pump 243 pumps the liquid from the storage tank 241 through the liquid level regulating port 213 to the regulating space of the outer heat exchanger 21. As the liquid level in the regulating space rises, the float 23 gradually floats upward under the buoyancy of the liquid, thereby gradually reducing the heat exchange area of the heat exchange space above the float 23. When the preset requirement is reached, the water pump 243 stops pumping liquid, and the shut-off valve 244 closes, keeping the float 23 at the position corresponding to the preset requirement.
[0052] It should be noted that when it is necessary to increase the heat exchange area of the heat exchange space above the float 23, the shut-off valve can be opened to allow the liquid in the adjustment space below the float 23 in the outer heat exchanger 21 to be discharged back into the storage tank 241, thereby causing the float 23 to move downward under its own gravity, thus increasing the heat exchange area of the heat exchange space.
[0053] In some embodiments, refer to Figure 6 and Figure 7As shown, a pressure sensor 25 is installed within the adjustment space of the outer heat exchanger 21 to identify the liquid filling volume based on the pressure value detected by the pressure sensor 25. In a specific implementation, the pressure sensor 25 can be positioned at a relatively low location within the adjustment space. When the liquid filling volume within the adjustment space of the outer heat exchanger 21 increases, the liquid pressure at the location of the pressure sensor 25 increases; conversely, when the liquid filling volume decreases, the liquid pressure at the location of the pressure sensor 25 decreases. This allows the liquid filling volume to be identified based on the pressure value detected by the pressure sensor 25, thereby matching the pressure value detected by the pressure sensor 25 with the target liquid temperature of the heater core 11. Specifically, the target liquid temperature of the heater core 11 can be pre-calibrated using the pressure value detected by the pressure sensor 25, for example, determining the pressure value associated with a target liquid temperature in degrees Celsius, to facilitate rapid temperature control by the air conditioning heating system.
[0054] In practice, when the water pump 243 pumps liquid into the regulating space below the float plate 23 inside the outer heat exchanger 21, the pressure sensor 25 detects the liquid pressure in the regulating space in real time. When the pressure value detected by the pressure sensor 25 reaches the set value, the shut-off valve 244 is closed. At this time, the float plate 23 blocks the liquid flow path inside the outer heat exchanger 21 below the float plate 23. The heat-storing liquid entering the outer heat exchanger 21 from the system inlet pipe 22 dissipates heat through the liquid flow path above the float plate 23. After heat dissipation, it flows through the outlet 212 into the warm air core 11, so that the temperature of the warm air core 11 reaches a suitable temperature.
[0055] It should be noted that when the target liquid temperature of the heating core 11 is calculated to be the highest set temperature, the float 23 floats upward to the highest position. The float 23 blocks the heat exchange flow path in the entire outer heat exchanger 21, leaving only the uppermost flow path, so that the heat storage liquid entering the outer heat exchanger 21 can flow into the heating core 11 through the liquid outlet 212 of the outer heat exchanger 21. At this time, the outer heat exchanger 21 does not perform the heat dissipation function.
[0056] When the target liquid temperature of the heating core 11 is calculated to be the lowest set temperature, the float 23 moves downward to the lowest position. At this time, only the lowest flow path in the heat exchange flow path of the outer heat exchanger 21 is blocked, so that the heat storage liquid entering the outer heat exchanger 21 has the largest heat exchange area with the outer heat exchanger 21, thereby achieving the purpose of rapidly cooling the heat storage liquid.
[0057] It should be noted that after completing a temperature adjustment operation (e.g., shutting off the air conditioning heating system), the shut-off valve 244 opens, the liquid level under the float 23 returns to its lowest position, the pressure sensor 25 receives the pressure value at this time, and the shut-off valve 244 closes. This resets the float 23 after each temperature adjustment operation, facilitating the next temperature adjustment.
[0058] In some embodiments, refer to Figure 6 and Figure 7 As shown, the outer heat exchanger 21 has multiple horizontal heat exchange channels 214 and two vertical connecting channels 215 inside. The multiple horizontal heat exchange channels 214 are arranged sequentially along the height direction of the outer heat exchanger 21, and the two ends of the multiple horizontal heat exchange channels 214 are respectively connected to the two vertical connecting channels 215. The outer heat exchanger 21 has two floating plates 23 inside, and the two floating plates 23 are respectively floating in the two vertical connecting channels 215.
[0059] In specific implementation, the horizontal cross-sectional dimensions of each float 23 are adapted to the horizontal cross-sectional dimensions of the vertical connecting channel 215, so that the float 23 can block the area of the corresponding vertical connecting channel 215 located below the float 23. That is, the float 23 separates the area of the vertical connecting channel 215 located above the float 23 from the area located below the float 23, preventing the heat storage liquid in the heat exchange space from flowing to the lower part through the float 23, and preventing the liquid in the regulating space from flowing to the upper part through the float 23. To ensure the sealing effect, the float 23 can be wrapped with a sealing ring or a sealing shell to ensure the reliability of the sealing. The height of each float 23 needs to be greater than the height of the horizontal heat exchange channel 214, so that the two floats 23 can respectively block the two ends of the horizontal heat exchange channel 214, thereby achieving the purpose of separating the regulating space located below the float 23 from the heat exchange space located above the float 23 using the two floats 23.
[0060] It should be noted that the liquid level adjustment port 213 of the outer heat exchanger 21 can be set on the lower channel wall of the lowest horizontal heat exchange channel 214 and is always connected to the lowest horizontal heat exchange channel 214. When the two floats 23 move downward to the lowest position, the two floats 23 can respectively block the two ends of the channel openings of the lowest horizontal heat exchange channel 214, so that the lowest horizontal heat exchange channel 214 forms an adjustment space, while the horizontal heat exchange channel 214 and the vertical connecting channel 215 located above the two floats 23 form a heat exchange space.
[0061] In some embodiments, both the inlet 211 and the outlet 212 are located on the upper part of the outer heat exchanger 21. A limiting member (not shown in the figure) is provided in the heat exchange space of the outer heat exchanger 21. The limiting member is located in the area below the inlet 211 and the outlet 212 to limit the highest movement position of the movable plate. This arrangement ensures that when the movable plate is in its highest movement position, the inlet 211 and the outlet 212 remain in communication, allowing the heat storage liquid entering the outer heat exchanger 21 to flow into the warm air core 11 through the outlet 212.
[0062] In specific implementation, the liquid inlet 211 of the outer heat exchanger 21 can be located on the upper channel wall of the uppermost horizontal heat exchange channel 214 of the outer heat exchanger 21, and is always in communication with the uppermost horizontal heat exchange channel 214. The liquid outlet 212 of the outer heat exchanger 21 can be located in the side area of the uppermost horizontal heat exchange channel 214 of the outer heat exchanger 21, and is always in communication with the uppermost horizontal heat exchange channel 214. There can be two limiting members, which are respectively located in two vertically connected channels 215, and the upper surface of the limiting members is lower than the lower channel wall of the uppermost horizontal heat exchange channel 214, or flush with the lower channel wall of the uppermost horizontal heat exchange channel 214.
[0063] It should be noted that since the float plate 23 floats upward using the buoyancy of the liquid, it is not necessary to set a limiting component. Instead, the maximum movement position of the float plate 23 can be controlled by controlling the amount of liquid injected, so as to ensure that when the float plate 23 floats upward to the maximum movement position, it will not block the two ends of the flow channel of the uppermost horizontal heat exchange channel 214.
[0064] In some embodiments, refer to Figure 2 As shown, there are two of each of the heating core 11 and the outer heat exchanger 21, and two of each of the system inlet pipe 22, connecting pipe 12 and system outlet pipe 13. One system inlet pipe 22, one outer heat exchanger 21, one connecting pipe 12, one heating core 11 and one system outlet pipe 13 are connected in sequence to form a heat exchange flow path, and another system inlet pipe 22, another outer heat exchanger 21, another connecting pipe 12, another heating core 11 and another system outlet pipe 13 are connected in sequence to form another heat exchange flow path.
[0065] In practice, the two heating cores 11 can correspond to the driver's side and the passenger's side of the cockpit respectively, and the heating core 11 on the driver's side and the heating core 11 on the passenger's side have their own independent heat exchange flow paths, thereby realizing dual-temperature zone control of the air conditioning and heating system.
[0066] In some embodiments, refer to Figure 2 and Figure 3 As shown, two heating cores 11 are arranged side by side, with a partition 14 between them. This arrangement separates the two heating cores 11, reducing heat transfer between them and thus better ensuring their respective temperature regulation effects, achieving better dual-temperature zone control. In a specific implementation, the partition 14 can be welded to the two heating cores 11 to form an integrated structure, reducing the space occupied by independently arranging the two heating cores 11.
[0067] In some embodiments, refer to Figure 3 and Figure 4As shown, the inlet of the heater core 11 is located at the upper part of the heater core 11, and the outlet of the heater core 11 is located at the lower part of the heater core 11. The interior of the heater core 11 is provided with multiple vertical heat exchange channels 111 and two horizontal connecting channels 112. The multiple vertical heat exchange channels 111 are arranged sequentially along the width direction of the heater core 11. The multiple vertical heat exchange channels 111 are connected to the two horizontal connecting channels 112 at both ends along the vertical direction. The upper horizontal connecting channel 112 is connected to the inlet of the heater core 11, and the lower horizontal connecting channel 112 is connected to the outlet of the heater core 11. This configuration allows the heat storage liquid to enter the heating air core 11 through the inlet, then disperse and flow through the upper horizontal connecting channel 112 into multiple vertical reversing channels, and finally converge through the lower horizontal connecting channel 112 before flowing out from the outlet of the heating air core 11. The heat storage liquid completes heat exchange with the heating air core 11 during the flow process.
[0068] Of course, the specific structure of the warm air core 11 is not limited to the above limitations and can be reasonably set according to the actual situation.
[0069] In some embodiments, refer to Figure 2 and Figure 5 As shown, the movable plate is a float plate 23, and each outer heat exchanger 21 is equipped with a float plate 23 inside. Each outer heat exchanger 21 is equipped with a liquid level regulating port 213 at its lower part. The regulating device is a liquid level regulating device 24, which includes a liquid storage tank 241, a connecting pipe 242, a water pump 243, and two shut-off valves 244. The connecting pipe 242 includes a main connecting pipe 2422, a three-way pipe 2421, and two branch pipes 2423. The main connecting pipe 2422 is connected to the two branch pipes 2423 through the three-way pipe 2421. The liquid storage tank 241 stores liquid and is connected to the main connecting pipe 2422. The two branch pipes 2423 are respectively connected to the liquid level regulating ports 213 of the two outer heat exchangers 21. The water pump 243 is installed on the main connecting pipe 2422, and the two shut-off valves 244 are respectively installed on the two branch pipes 2423. This configuration allows for independent temperature control of the two warm air cores 11 by using a liquid storage tank 241, a water pump 243, and two shut-off valves 244.
[0070] In other words, the temperature on the driver's side and the passenger side can be controlled independently, with the same control logic. When the set temperature values on both sides are different, the shut-off valve 244 corresponding to the outer heat exchanger 21 on the side that first reaches the required pressure value closes. When the pressure value on the other side reaches the monitoring value, both shut-off valves 244 close completely, and the water pump 243 shuts down.
[0071] Of course, in specific implementation, two independent liquid level adjustment devices 24 can also be set up to achieve independent temperature control of the two warm air cores 11.
[0072] It should be noted that when other types of adjustment devices are used, such as electric push rods or cylinders, two independent adjustment devices can also be set up to achieve independent temperature control of the two warm air cores 11. The settings can be reasonably configured according to the actual situation.
[0073] Other embodiments of this application provide a vehicle including an air conditioning and heating system as described in any of the above embodiments, and thus have the beneficial effects of the air conditioning and heating system described in any of the above embodiments, which will not be repeated here.
