[0046] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0047] like Figures 1 to 9 As shown, Embodiment 1 of the present invention provides a heat exchanger, which includes an inlet manifold 10, an outlet manifold 20, a heat exchange branch pipe 30, and an adjusting member 40. The heat exchange branch pipe 30 has a heat exchange inlet 31 and a heat exchange outlet 32. The heat exchange inlet 31 is connected to the inlet manifold 10, and the heat exchange outlet 32 ​​is connected to the outlet manifold 20. The adjusting member 40 is adjustablely disposed within the inlet manifold 10 or the heat exchange branch pipe 30. The shape of the adjusting member 40 is adapted to the heat exchange inlet 31 so that the adjusting member 40 can block, avoid, or partially block the heat exchange inlet 31.

[0048] By adjusting the position of the adjusting member 40, the heat exchange inlet 31 can be blocked, bypassed, or partially blocked using the adjusting member 40. This facilitates the regulation of the refrigerant flow through the heat exchange inlet 31. Adjusting the adjusting member 40 allows for control of the heat exchanger, thus meeting different cooling and heating needs within the vehicle. Therefore, the heat exchanger provided in this embodiment solves the technical problem of accurately controlling the amount of refrigerant involved in heat exchange in existing technologies.

[0049] It should be noted that the heat exchanger here can be an indoor heat exchanger or an outdoor heat exchanger. For vehicles, the indoor heat exchanger is also called the vehicle interior heat exchanger, and the outdoor heat exchanger is also called the vehicle exterior heat exchanger.

[0050] Specifically, the heat exchanger also includes a drive component 50, which is drivenly connected to the regulating component 40. The drive component 50 is located outside the inlet manifold 10 and outside the heat exchange branch pipe 30. This structural arrangement facilitates effective control and adjustment of the regulating component 40, enabling regulation of the refrigerant. In this embodiment, the drive component 50 can be a stepper motor. The stepper motor is used to drive and adjust the amount of refrigerant entering the branch pipe from the main pipe of the external or internal heat exchanger, thus achieving different heat exchange requirements under different conditions. By placing the drive component 50 outside the inlet manifold 10 and outside the heat exchange branch pipe 30, maintenance and adjustment of the drive component 50 are also facilitated.

[0051] Specifically, in this embodiment, the refrigerant flow rate of the heat exchanger can be determined according to the demand for cooling and heating (parameters such as air conditioner outlet temperature), thereby controlling the operation of the stepper motor accordingly.

[0052] In this embodiment, the driving end of the driving member 50 is rotatably disposed, and the adjusting member 40 is rotatably disposed within the inlet manifold 10. The heat exchanger also includes a transmission rod 60, at least a portion of which extends out of the end of the inlet manifold 10 and is connected to the driving end of the driving member 50. The adjusting member 40 is connected to the transmission rod 60, so that the driving member 50 drives the adjusting member 40 to rotate via the transmission rod 60. This structural arrangement is simple and facilitates stable position adjustment of the adjusting member 40. Furthermore, the transmission rod 60 has minimal impact on the flow rate within the inlet manifold 10 and will not significantly affect the refrigerant flow rate within the inlet manifold 10.

[0053] Specifically, the transmission rod 60 includes a first transmission rod 61 and a second transmission rod 62. The first transmission rod 61 extends along the length of the inlet manifold 10, with one end extending beyond the end of the inlet manifold 10 and connected to the driving end of the driving member 50. One end of the second transmission rod 62 is connected to the adjusting member 40, and the other end is connected to the other end of the first transmission rod 61. The extension direction of the second transmission rod 62 is set at a first preset angle to the extension direction of the first transmission rod 61. This simplifies the structure of the transmission rod 60 and minimizes the impact on the normal flow of refrigerant in the inlet manifold 10 while stably driving the adjusting member 40 to rotate. Specifically, the first preset angle can be 90°.

[0054] In this embodiment, the inlet manifold 10 is a circular tube structure, the adjusting member 40 is an arc-shaped plate adapted to the inner wall of the inlet manifold 10, and the first transmission rod 61 is located at the axis of symmetry of the inlet manifold 10. This structural arrangement facilitates the movement of the arc-shaped plate along the periphery of the inner wall of the manifold, thereby enabling the arc-shaped plate to smoothly block, avoid, or partially block the heat exchange inlet 31.

[0055] In one embodiment, there are multiple heat exchange branch pipes 30, which are spaced apart along the axial direction of the inlet manifold 10. The adjusting member 40 is a strip plate extending along the axial direction of the inlet manifold 10. The length of the strip plate along the axial direction of the inlet manifold 10 is at least greater than the total installation length of two adjacent heat exchange branch pipes 30 along the axial direction of the inlet manifold 10. This facilitates the simultaneous blocking, avoidance, or partial blocking of the heat exchange inlets 31 of at least two adjacent heat exchange branch pipes 30 when adjusting the position of the adjusting plate, thereby facilitating the adjustment of the refrigerant flow rate of at least two adjacent heat exchange branch pipes 30. Preferably, the length of the strip plate along the axial direction of the inlet manifold 10 can be greater than the total installation length of the multiple heat exchange branch pipes 30 along the axial direction of the inlet manifold 10, thus facilitating the simultaneous blocking, avoidance, or partial blocking of the heat exchange inlets 31 of multiple heat exchange branch pipes 30 along the axial direction when adjusting the position of the adjusting plate. Specifically, the heat exchanger in this embodiment can be set as an external heat exchanger.

[0056] It should be noted that two adjacent heat exchange branch pipes 30 include the first branch pipe and the second branch pipe. The "total installation length of two adjacent heat exchange branch pipes 30 in the axial direction of the inlet manifold 10" refers to the length between the end of the first branch pipe away from the second branch pipe in the axial direction of the inlet manifold 10 and the end of the second branch pipe away from the first branch pipe in the axial direction of the inlet manifold 10.

[0057] Specifically, in this embodiment, the adjusting member 40 can adjust the flow rate of multiple heat exchange branch pipes 30 arranged at intervals in the axial direction, that is, the length of the adjusting member 40 is greater than the total installation length of the multiple heat exchange branch pipes 30 in the axial direction of the inlet manifold 10.

[0058] In another embodiment, there are multiple heat exchange branch pipes 30, which are spaced apart circumferentially along the inlet manifold 10. An adjusting member 40 extends circumferentially along the inlet manifold 10, and the arc length of the adjusting member 40 in the circumferential direction of the inlet manifold 10 is at least greater than the total arc length of two adjacent heat exchange branch pipes 30 in the circumferential direction of the inlet manifold 10. This facilitates the simultaneous blocking, avoidance, or partial blocking of the heat exchange inlets 31 of at least two adjacent heat exchange branch pipes 30 when adjusting the position of the adjusting plate, thus enabling convenient adjustment of the refrigerant flow rate of at least two adjacent heat exchange branch pipes 30. Preferably, the arc length of the strip plate in the circumferential direction of the inlet manifold 10 can be greater than the total arc length of the multiple heat exchange branch pipes 30 in the circumferential direction of the inlet manifold 10, thereby facilitating the simultaneous blocking, avoidance, or partial blocking of the heat exchange inlets 31 of multiple heat exchange branch pipes 30 in the circumferential direction when adjusting the position of the adjusting plate. Specifically, the heat exchanger in this embodiment can be configured as an in-vehicle heat exchanger.

[0059] It should be noted that the two adjacent heat exchange branch pipes 30 include the third branch pipe and the fourth branch pipe. The "total arc length of the two adjacent heat exchange branch pipes 30 in the circumferential direction of the inlet manifold 10" refers to the arc length between the end of the third branch pipe away from the fourth branch pipe in the circumferential direction of the inlet manifold 10 and the end of the fourth branch pipe away from the third branch pipe in the circumferential direction of the inlet manifold 10.

[0060] The actual number and arrangement of heat exchangers need to be calculated specifically during actual use, including the length and diameter of the inlet manifold 10, the length and diameter of the outlet manifold 20, the length and diameter of each heat exchange branch pipe 30, the number of rows and spacing of the heat exchange branch pipes 30, and the number of heat exchange branch pipes 30 in each row (e.g., Figure 6 and Figure 7 As shown, this diagram is not only a simplified design diagram of the heat exchanger adjustment section inside the vehicle, but also a simplified design diagram of each row of heat exchange branch pipes 30; each row of heat exchange branch pipes 30 can be designed as follows: Figure 6 and Figure 7 The design shown is in three units, but it can also be designed with other numbers.

[0061] The relevant formulas for heat exchange involved in this invention are as follows:

[0062] Q = Um·A·ΔTm;

[0063] Q – Total heat exchange, in W;

[0064] Um—average heat transfer coefficient, unit is W / (m²) 2 ·k);

[0065] A – Heat exchange area, in m² 2 ;

[0066] ΔTm — Average heat transfer temperature difference, in °C.

[0067] like Figure 10 As shown, Embodiment 2 of the present invention provides a vehicle air conditioning system, which includes an indoor heat exchanger 70 and an outdoor heat exchanger 80. The indoor heat exchanger 70 uses the heat exchanger provided above; or, the outdoor heat exchanger 80 uses the heat exchanger provided above; or, both the indoor heat exchanger 70 and the outdoor heat exchanger 80 use the heat exchanger provided above.

[0068] Specifically, the outdoor heat exchanger 80 is mounted on the vehicle roof, protruding from the roof. This structural arrangement allows the outdoor heat exchanger 80 to maximize the use of wind energy—specifically, the wind energy generated by the air flowing backward relative to the vehicle's forward direction during operation—eliminating the need for an external fan. This not only effectively reduces noise but also saves energy. Furthermore, by adopting the structure described in the above embodiment, the amount of refrigerant entering the heat exchange branch pipe can be easily adjusted, thus facilitating the fulfillment of different heat exchange requirements under varying conditions. The indoor heat exchanger 70 and outdoor heat exchanger 80 in this embodiment can be used in conjunction with a forced convection device, which can be a fan.

[0069] In this embodiment, both the inlet manifold 10 and the outlet manifold 20 of the outdoor heat exchanger 80 are set at a second preset angle to the top surface of the vehicle roof, and the heat exchange branch pipes 30 of the outdoor heat exchanger 80 are set parallel to the top surface of the vehicle roof. This arrangement facilitates the full utilization of wind energy for more effective heat exchange in the outdoor heat exchanger 80. Specifically, the second preset angle can be between 60° and 90°, including both 60° and 90°.

[0070] Specifically, the interior heat exchanger 70 is installed inside the vehicle and is located in the vehicle's roof. The inlet manifold 10 and outlet manifold 20 of the interior heat exchanger 70 are respectively located on both sides of the vehicle's roof, and the heat exchange branch pipes 30 of the interior heat exchanger 70 are arranged parallel to the top surface of the vehicle's roof. This layout facilitates heat exchange by the interior heat exchanger 70. The vehicle air conditioning system in this embodiment also includes an interior fan, which is positioned opposite the interior heat exchanger 70. The interior fan can use a smaller airflow fan, thereby reducing the noise of the entire vehicle air conditioning system by more than 10 dB compared to conventional vehicle air conditioning systems.

[0071] It should be noted that the top surface of the vehicle roof can refer to the roof surface located outdoors.

[0072] The vehicle air conditioning system also includes a four-way valve 90, a compressor 100, and a throttle valve 110. The vehicle air conditioning system provided in the above embodiment has the following advantages: Significantly lower noise; due to the absence of an external fan and the single, relatively small airflow of the internal fan, the overall system noise is estimated to be more than 10 dB lower than that of traditional bus heat pump air conditioning systems. Significant energy savings; during system operation, the energy consumption is mainly limited to driving the compressor 100, with very little energy required by the internal fan, resulting in significant energy savings. Enhanced comfort and more precise control; floor-mounted interior heating combined with downdraft ventilation and the introduction of fresh air into the vehicle provides greater comfort and fresher air compared to traditional bus heating systems.

[0073] Embodiment 3 of the present invention provides a vehicle including the vehicle air conditioning system provided in Embodiment 2 above. The vehicle in this embodiment is not limited to a bus.

[0074] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects: the heat exchanger is adjustable using a stepper motor, and the air energy of the bus itself is utilized, effectively meeting the cooling and heating needs of the vehicle interior and providing more precise control of the heat exchanger. The outdoor heat exchanger uses natural convection, and the interior uses a smaller internal fan, resulting in significantly lower noise than traditional heating systems. Energy consumption is mainly due to the compressor, resulting in significant energy savings compared to traditional bus heating systems. Combined with floor heating, the system provides both air supply and fresh air intake, making it more comfortable and providing better air quality than traditional bus heating systems.
