In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0028] This application is described below with reference to the accompanying drawings and specific embodiments:

[0029] This application provides a heat exchange device, such as... Figure 1 and Figure 2 As shown, the heat exchange device in this embodiment includes:

[0030] The heat exchange duct shell 100 is provided with a heat exchange duct inside. The heat exchange duct shell 100 has an air inlet 110 and an air outlet 120 at opposite ends.

[0031] The condenser 200 is installed in the heat exchange air duct. A first air duct 210 is provided in the middle of the condenser 200 or on the first side of the condenser 200, connecting the air inlet 110 and the air outlet 120. The condenser 200 is provided with a condensation vent that connects the first air duct 210 and the outer periphery of the condenser 200.

[0032] The radiator 300 is sleeved on the outside of the condenser 200 or disposed on the second side of the condenser 200, the second side of the condenser 200 being opposite to the first side of the condenser 200. A second air duct 310 is formed between the radiator 300 and the heat exchange air duct shell 100, connecting the air inlet 110 and the air outlet 120. The radiator 300 is provided with a heat dissipation ventilation opening connecting the second air duct 310 and the condenser 200.

[0033] An air inlet regulating component 400 is disposed at one end of the first air duct 210 and the second air duct 310 adjacent to the air inlet 110. The air inlet regulating component 400 is used to switch the connection state between the air inlet 110 and the first air duct 210 and the second air duct 310; and,

[0034] An air outlet regulating component 500 is disposed at one end of the first air duct 210 and the second air duct 310 adjacent to the air outlet 120. The air outlet regulating component 500 is used to switch the connection state between the air outlet 120 and the first air duct 210 and the second air duct 310.

[0035] In this embodiment, the heat exchange device improves the structure and relative position of the condenser 200 and the radiator 300, forming a first air duct 210 and a second air duct 310 within the heat exchange duct shell 100. The airflow path can be flexibly controlled via the inlet regulating component 400 and the outlet regulating component 500, controlling the order in which air flows through the first air duct 210 and the second air duct 310, thereby controlling the different heat exchange relationships between the condenser 200 and the heat exchanger. This allows the heat exchange device to simultaneously meet the performance requirements of heat dissipation, cooling, and heating. Furthermore, under heating conditions, the condenser 200 can utilize the heat discharged by the radiator 300, improving energy utilization and thus reducing energy consumption for heating in winter and improving the energy efficiency of the heat pump system.

[0036] In a vehicle's heat pump system, the condenser 200 plays different roles under different operating conditions, and the required air temperature also varies. In related technologies, the radiator 300 and condenser 200 of the heat pump system are mechanically integrated, with the condenser 200 positioned before the radiator 300. Air flows from the condenser 200 to the radiator 300, achieving good cooling performance and meeting the cooling needs of high-temperature environments. However, in low-temperature environments, the condenser 200, as a heat exchange component, needs to transfer external heat to the vehicle interior. Positioning the condenser 200 before the radiator 300 prevents the utilization of the radiator 300's heat, necessitating electric heating for vehicle reheating. This results in higher energy consumption for the heat pump system, impacting the vehicle's driving range.

[0037] In this embodiment, the heat exchange device can be used in a vehicle's heat pump system. For example, Figure 1As shown, the refrigerant inlet 220 of the condenser 200 is connected to the compressor in the heat pump system via a pipeline, and is used for heat dissipation or absorption of heat from the environment depending on the different operating conditions of the heat pump system; the radiator 300 is used for heat dissipation of the vehicle's power system, and the heat dissipation medium inlet 320 of the radiator 300 is connected to the heat dissipation device of the power system via a pipeline. Under different external temperature conditions, the airflow path in the heat exchange device can be flexibly selected according to the vehicle's cooling and heating needs.

[0038] In the cooling mode of a heat pump system, such as Figure 3 and Figure 4 As shown, the heat exchange device blocks the second air duct 310 and opens the first air duct 210 through the air inlet regulating component 400, so that the air inlet 110 is connected to the first air duct 210. At the same time, it blocks the first air duct 210 and opens the second air duct 310 through the air outlet regulating component 500, so that the air outlet 120 is connected to the second air duct. Thus, the air first flows through the first air duct 210 and exchanges heat with the condenser 200, so that the condenser 200 converts the high-temperature and high-pressure gaseous refrigerant sent by the compressor into liquid refrigerant. Then it exchanges heat with the radiator 300, so that the hot heat dissipation medium in the radiator 300 dissipates heat and cools down. After that, the air enters the second air duct 310 and is discharged from the heat exchange device through the air outlet 120.

[0039] In the heating mode of a heat pump system, such as Figure 5 and Figure 6 As shown, the heat exchange device blocks the first air duct 210 and opens the second air duct 310 through the air inlet regulating component 400, so that the air inlet 110 is connected to the second air duct 310. At the same time, it blocks the second air duct 310 and opens the first air duct 210 through the air outlet regulating component 500, so that the air outlet 120 is connected to the first air duct 210. Thus, the air first flows through the second air duct 310, exchanges heat with the radiator 300, absorbs the heat of the radiator 300, and cools down the hot heat dissipation medium in the radiator 300. Then it exchanges heat with the condenser 200, heats the condenser 200, and converts the low-temperature, low-pressure liquid refrigerant sent by the compressor into a high-temperature refrigerant. After that, the air enters the first air duct 210 and is discharged from the heat exchange device through the air outlet 120. In this embodiment, the heat exchange device can make full use of the heat from the radiator 300 for heating, thereby improving energy efficiency, avoiding or reducing the use of electric heating, saving electricity consumption, and extending the driving range.

[0040] Compared to the 300-type flat-plate heatsink structure in related technologies, such as Figure 1 and Figure 2As shown, in this embodiment, the radiator 300 is sleeved on the outside of the condenser 200 to form a cylindrical structure. A first air duct 210 is formed in the middle of the condenser 200, and a second air duct 310 with an annular structure is formed on the outside of the radiator 300. The main influencing factors of the heat exchange area between the first air duct 210 and the condenser 200, and the heat exchange area between the second air duct 310 and the radiator 300, are the depth of the condenser 200 and the radiator 300. For the arrangement environment with limited frontal area and large depth distance, the heat dissipation area can be effectively increased, providing a new form of radiator 300 and a new solution for the ever-changing structural layout of electric vehicles.

[0041] In this embodiment, as Figure 1 and Figure 2 As shown, the heat exchange duct shell 100, condenser 200, radiator 300, air inlet regulating component 400 and air outlet regulating component 500 of the heat exchange device are all circular in cross-section, and all components are coaxial.

[0042] In other embodiments, the various structures of the heat exchange device can also adopt different shapes. For example, the heat exchange duct shell 100, condenser 200, radiator 300, inlet air regulating component 400, and outlet air regulating component 500 may all have the same polygonal cross-section. Alternatively, the heat exchange duct shell 100, radiator 300, inlet air regulating component 400, and outlet air regulating component 500 may all have the same polygonal cross-section, while the condenser 200 may have a different polygonal or circular cross-section. Those skilled in the art can adjust the specific structure of the heat exchange duct shell 100, condenser 200, radiator 300, inlet air regulating component 400, and outlet air regulating component 500 from the perspectives of heat dissipation area, airflow rate in the first air duct 210, and airflow smoothness.

[0043] In other embodiments, the condenser 200 and radiator 300 are not limited to the above-described arrangement. For example, the condenser 200 is disposed within the heat exchange duct housing 100, forming a first air duct 210 between the first side of the condenser 200 and the heat exchange duct housing 100; the radiator 300 is stacked on the second side of the condenser 200, with the second side of the condenser 200 opposite to the first side, thereby forming a second air duct 310 between the radiator 300 and the heat exchange duct housing 100. The connection between the first air duct 210 and the second air duct 310 is adjusted by the inlet air regulating component 400 and the outlet air regulating component 500, thereby adjusting the order in which air flows through the condenser 200 and the radiator 300. Its design principle is the same as in the above embodiments and will not be repeated here.

[0044] As an optional implementation, the air intake regulating assembly 400 includes:

[0045] An air inlet fixed grille 410 is fixedly installed on the heat exchange air duct shell 100. The air inlet fixed grille 410 has a first air duct inlet 411 that connects the first air duct 210 and the air inlet 110, and a second air duct inlet 412 that connects the second air duct 310 and the air inlet 110. The first air duct inlet 411 and the second air duct inlet 412 are staggered.

[0046] The movable air intake grille 420 is rotatably mounted on the fixed air intake grille 410. The movable air intake grille 420 includes an air intake blocking fan blade 421. The air intake blocking fan blade 421 is used to switch between blocking the first air duct inlet 411 and the second air duct inlet 412.

[0047] The air outlet adjustment assembly 500 includes:

[0048] An air outlet fixed grille 510 is fixedly installed on the heat exchange air duct shell 100. The air outlet fixed grille 510 has a first air duct outlet 511 that connects the first air duct 210 and the air outlet 120. The air outlet fixed grille 510 has a second air duct outlet 512 that connects the second air duct 310 and the air outlet 120. The first air duct outlet 511 and the second air duct outlet 512 are staggered.

[0049] The movable air outlet grille 520 is rotatably mounted on the fixed air outlet grille 510. The movable air outlet grille 520 includes an air outlet blocking fan blade 521. The air outlet blocking fan blade 521 is used to switch between blocking the first air duct outlet 511 and the second air duct outlet 512.

[0050] In this embodiment, as Figure 3 and Figure 5 As shown, the air inlet fixed grille 410 is fixedly installed on the heat exchange duct shell 100 and fits against the condenser 200 and radiator 300. The shape of the air inlet fixed grille 410 matches the structure of the heat exchange duct shell 100, so that the air inlet fixed grille 410 can completely block the heat exchange duct inside the heat exchange duct shell 100. Several first air duct inlets 411 are opened on the air inlet fixed grille 410 at positions corresponding to the first air duct 210, so that the first air duct 210 can be connected to the air inlet 110; several second air duct inlets 412 are opened on the air inlet fixed grille 410 at positions corresponding to the second air duct 310, so that the second air duct 310 can be connected to the air inlet 110, while the number of first air duct inlets 411 and second air duct inlets 412 are the same and staggered.

[0051] Correspondingly, the movable air intake grille 420 is rotatably mounted on the fixed air intake grille 410. The movable air intake grille 420 includes a plurality of air intake blocking fan blades 421, the number of which is the same as the number of the first air duct inlets 411 and the second air duct inlets 412, and the structure of the air intake blocking fan blades 421 matches the structure of the first air duct inlets 411 and the second air duct inlets 412. The air intake blocking fan blades 421 can block all of the first air duct inlets 411. By rotating the movable air intake grille 420 relative to the fixed air intake grille 410, the position of the air intake blocking fan blades 421 can be adjusted, so that the air intake blocking fan blades 421 block all of the second air duct inlets 412. That is, by rotating the movable air intake grille 420 relative to the fixed air intake grille 410, the blocking position of the movable air intake grille 420 can be adjusted, so that the air inlet 110 is connected to the first air duct 210, or so that the air inlet 110 is connected to the second air duct 310.

[0052] In this embodiment, as Figure 3 and Figure 5 As shown, the air outlet fixed grille 510 is fixedly installed on the heat exchange duct shell 100 and fits against the condenser 200 and the radiator 300. The shape of the air outlet fixed grille 510 matches the structure of the heat exchange duct shell 100, so that the air outlet fixed grille 510 can completely block the heat exchange duct inside the heat exchange duct shell 100. Several first air duct outlets 511 are opened on the air outlet fixed grille 510 at positions corresponding to the first air duct 210, so that the first air duct 210 can be connected to the air outlet 120; several second air duct outlets 512 are opened on the air outlet fixed grille 510 at positions corresponding to the second air duct 310, so that the second air duct 310 can be connected to the air outlet 120, while the number of first air duct outlets 511 and second air duct outlets 512 are the same and staggered.

[0053] Correspondingly, the movable air outlet grille 520 is rotatably mounted on the fixed air outlet grille 510. The movable air outlet grille 520 includes a plurality of air outlet blocking fan blades 521, the number of which is the same as the number of the first air duct outlet 511 and the second air duct outlet 512, and the structure of the air outlet blocking fan blades 521 matches the structure of the first air duct outlet 511 and the second air duct outlet 512. The air outlet blocking fan blades 521 can block all of the first air duct outlet 511. By rotating the movable air outlet grille 520 relative to the fixed air outlet grille 510, the position of the air outlet blocking fan blades 521 can be adjusted, so that the air outlet blocking fan blades 521 block all of the second air duct outlet 512. That is, by rotating the movable air outlet grille 520 relative to the fixed air outlet grille 510, the blocking position of the movable air outlet grille 520 can be adjusted, so that the air outlet 120 is connected to the first air duct 210, or the air outlet 120 is connected to the second air duct 310.

[0054] As an optional implementation, the heat exchange device also includes a drive motor, which drives the inlet movable grille 420 to rotate relative to the inlet fixed grille 410 and the outlet movable grille 520 to rotate relative to the outlet fixed grille 510.

[0055] In this embodiment, a drive motor can be installed in the first air duct 210, so that the drive motor can be connected to the inlet movable grille 420 and the outlet movable grille 520 through a transmission structure. Different transmission structures can be designed to make the inlet movable grille 420 and the outlet movable grille 520 rotate respectively, so as to control the opening and closing of the first air duct 210 and the second air duct 310.

[0056] In other embodiments, the heat exchange device may also be equipped with two drive motors, which are used to drive the inlet movable grille 420 and the outlet movable grille 520 respectively. The specific positions of the drive motors can be adaptively adjusted according to the structure and position of the inlet regulating component 400 and the outlet regulating component 400.

[0057] As an optional implementation, the heat exchange device also includes a bracket 600, which is mounted on the heat exchange duct shell 100; the condenser 200 and the radiator 300 are coaxially fixed on the bracket 600.

[0058] In this embodiment, as Figure 2 As shown, the bracket 600 can be fixedly mounted on the heat exchange duct shell 100, thereby supporting the condenser 200 and allowing the condenser 200 to be suspended within the heat exchange duct shell 100, reserving a certain amount of space for the radiator 300 and the second air duct 310. At the same time, the bracket 600 can support the radiator 300, allowing the radiator 300 to be fitted onto the condenser 200, avoiding the need for the condenser 200 to support the radiator 300, thus avoiding a large burden on the condenser 200. Furthermore, by supporting the radiator 300 with the bracket 600, the radiator 300 can be suspended within the heat exchange duct shell 100, thereby reserving space for the second air duct 310 between the radiator 300 and the heat exchange duct shell 100.

[0059] In this embodiment, the structure of the bracket 600 can be adjusted according to the structure of the condenser 200, the structure of the radiator 300, and the relative positions of the condenser 200 and the radiator 300, which will not be described in detail here.

[0060] As an alternative implementation, there is a gap between the radiator 300 and the condenser 200.

[0061] In this embodiment, as Figure 1As shown, a certain gap is provided between the radiator 300 and the condenser 200. When air flows from the radiator 300 to the condenser 200, or from the condenser 200 to the radiator 300, the air can undergo sufficient heat exchange within this gap, thereby increasing the heat exchange area and heat exchange efficiency.

[0062] As an alternative implementation, the condensation vents and the heat dissipation vents are staggered.

[0063] In this embodiment, as Figure 1 As shown, the condenser vents and heat dissipation vents are staggered, so that when air flows from the radiator 300 to the condenser 200, or from the condenser 200 to the radiator 300, the air can enter the gap between the radiator 300 and the condenser 200, thus extending the path length of the airflow and preventing the air from passing through the radiator 300 and the condenser 200 through the shortest path. This avoids the reduction in heat exchange efficiency caused by a short heat exchange path and a small heat exchange area.

[0064] As an optional implementation, the heat exchange duct shell 100 is provided with an air guide section 130 at one end near the air inlet 110, and the cross-sectional area of ​​the air guide section 130 expands from the air inlet 110 toward the air inlet regulating component 400.

[0065] When the windward area is small, the corresponding air inlet 110 is also small. At the same time, when the air first needs to enter the second air duct 310, if the airflow is not guided, it is easy to cause turbulence in the heat exchange air duct between the air inlet 110 and the air inlet regulating component 400, which will affect the heat exchange efficiency of the heat exchange device.

[0066] In this embodiment, as Figure 6 As shown, a guide section 130 is provided at one end of the heat exchange duct shell 100 near the air inlet 110. The cross-sectional area of ​​the guide section 130 expands from the air inlet 110 toward the air inlet regulating component 400. Under the action of the guide section 130, the airflow is smoothly directed to the second air duct 310, making the airflow smoother and thus increasing the air flow in the heat exchange device and improving the heat exchange efficiency.

[0067] As an optional implementation, the heat exchange device also includes a fan 700, which is disposed inside the heat exchange duct housing 100, or disposed outside the heat exchange duct housing 100 corresponding to the air inlet 110 or the air outlet 120.

The fan 700 can be installed inside the heat exchange duct housing 100, for example, at the air inlet 110 or the air outlet 120; alternatively, the fan 700 can also be installed outside the heat exchange duct housing 100, corresponding to the air inlet 110 or the air outlet 120.

[0073] Since the automobile provided by this invention includes the heat pump system of the above-mentioned technical solution, the automobile provided by this invention has all the beneficial effects of the above-mentioned heat pump system, which will not be elaborated here.

[0074] In this embodiment, the vehicle can be an electric vehicle or a fuel cell vehicle.

[0075] When the heat exchange device of this application is applied to an electric vehicle, the operating mode is as follows:

[0076] When the ambient temperature is high, there is usually a need for cooling in the car cabin, such as... Figure 3 and Figure 4 As shown, the intake air regulating component 400 and the exhaust air regulating component 500 are controlled to connect the intake 110 to the first air duct 210 and the exhaust 120 to the second air duct 310. Cold air from outside the vehicle flows sequentially through the intake 110, the first air duct 210, the condenser 200, the radiator 300, the second air duct 310, and the exhaust 120. This ensures that the cold air first flows through the subcooling zone of the condenser 200 to meet cooling requirements, and then flows through the radiator 300 to meet the heat dissipation requirements of the vehicle's components. In this scenario, as... Figure 3As shown, the cooperation of the movable air intake grille 420 and the fixed air intake grille 410 closes the second air duct 310 between the air intake 110 and the radiator 300, and opens the first air duct 210 between the air intake 110 and the condenser 200; the cooperation of the movable air outlet grille 520 and the fixed air outlet grille 510 opens the second air duct 310 between the air outlet 120 and the radiator 300, and closes the first air duct 210 between the air outlet 120 and the condenser 200.

[0077] When the ambient temperature is low, there is usually a need for heating in the car cabin. In related technologies, the commonly used heating method for electric vehicles is a heat pump system combined with PTC heating. The heating principle of the heat pump system is a reverse cooling cycle, that is, heat is transferred from outside the car to the car through the phase change of the refrigerant, thereby achieving a heating effect. However, it is greatly affected by the ambient temperature. When the ambient temperature is too low, it cannot meet the heating needs, and PTC heating is required. This results in high power consumption, which reduces the driving range of electric vehicles.

[0078] In this embodiment, as Figure 5 and Figure 6 As shown, the intake air regulating component 400 and the exhaust air regulating component 500 are controlled to connect the intake 110 to the second air duct 310 and the exhaust 120 to the first air duct 210. Cold air from outside the vehicle flows sequentially through the intake 110, the second air duct 310, the radiator 300, the condenser 200, the first air duct 210, and the exhaust 120. This ensures that the cold air first flows through the radiator 300, meeting the heat dissipation requirements while also absorbing heat from the radiator 300 for use in the heat pump system, improving the heating capacity of the heat pump system, reducing power consumption, and minimizing the impact of ambient temperature on the heating effect of the heat pump system. In this scenario, as... Figure 5 As shown, the cooperation of the movable air intake grille 420 and the fixed air intake grille 410 opens the second air duct 310 between the air intake 110 and the radiator 300, and closes the first air duct 210 between the air intake 110 and the condenser 200; the cooperation of the movable air outlet grille 520 and the fixed air outlet grille 510 closes the second air duct 310 between the air outlet 120 and the radiator 300, and opens the first air duct 210 between the air outlet 120 and the condenser 200.
