[0002] Traditional vehicle air conditioners include a cooling core and a heating core, wherein the cooling core and the heating core are independently arranged. Cooling core: As a cold source, it is integrated into the air conditioner box. The temperature of the air flowing through it is reduced by evaporation of the refrigerant inside the core, thereby realizing the adjustment of the cooling function in the car. Heating core: As a heat source, it is integrated into the air conditioner box. The temperature of the air flowing through it is heated by cooling the refrigerant inside the core, thereby realizing the adjustment of the heating function in the car.

[0003] The cooling and heating cores of traditional air conditioners are arranged front and back in the air conditioner, with the cooling core in front and the heating core in the back. Due to the front-to-back arrangement of the two cores (cooling core in front and heating core in the back), in heating mode, the airflow must first pass through the cooling core before reaching the heating core. This increases the resistance along the way, and the heating mode needs to overcome the resistance along the way.

[0034] The core of the utility model is to provide a vehicle-mounted air conditioner and a vehicle, so as to reduce the resistance along the way caused by a refrigeration core in the vehicle-mounted air conditioner.

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation modes.

[0036] Please refer to Figures 1 to 8 .

[0037] In a specific implementation, the vehicle air conditioner provided by the specific embodiment of the utility model includes a heat exchange core 100 and a heat exchange group 200. The heat exchange core 100 includes a mounting frame 107 and a cooling core and a heating core mounted on the mounting frame 107.

[0038] The heat exchange group 200 includes a ventilation channel and an opening and closing module. The ventilation channel includes a cooling ventilation channel 201 corresponding to the cooling core and a heating ventilation channel 202 corresponding to the heating core. The opening and closing module is used to open and close the cooling ventilation channel 201 and the heating ventilation channel 202. Specifically, the heat exchange group 200 includes a first rolling curtain arranged at the position of the cooling ventilation channel 201 and a second rolling curtain arranged at the position of the heating ventilation channel 202. When working, the opening and closing module drives the first rolling curtain and the second rolling curtain to move.

[0039] In order to reduce the occupied volume, preferably, the heat exchange group 200 includes a first louver 203 arranged at the position of the cooling and ventilation channel 201, and the opening and closing module includes a first driving module that controls the opening and closing of the first louver 203.

[0040] In a specific embodiment, the heat exchange group 200 includes a second louver 204 disposed at the position of the heating and ventilation channel 202, and the opening and closing module includes a second driving module for controlling the opening and closing of the second louver 204. For ease of installation, preferably, the first louver 203 and the second louver 204 are louvers of the same structure. Specifically, the first louver 203 and the second louver 204 are respectively sleeved and arranged in linkage.

[0041] In specific configuration, the first louver sheet 203 and the second louver sheet 204 may be plastic sheets or metal sheets.

[0042] In specific use, when the refrigeration core is working, the opening and closing module opens the refrigeration ventilation channel 201 and closes the heating ventilation channel 202. When the heating core is working, the opening and closing module closes the refrigeration ventilation channel 201 and opens the heating ventilation channel 202.

[0043] From the above description, it can be seen that in the vehicle air conditioner provided in the specific embodiment of the present application, the present application integrates the cooling core and the heating core of the heat exchange core 100 in the installation frame 107, and adjusts the opening and closing of the corresponding cooling ventilation channel 201 and the heating ventilation channel 202 according to the working mode of the heat exchange core 100, thereby effectively solving the problem of high resistance along the way caused by the airflow having to pass through the cooling core in the original heating mode.

[0044] In a specific embodiment, the first louver 203 and the second louver 204 are both installed on the installation frame 107. Specifically, the opposite ends of the first louver 203 and the second louver 204 are rotatably connected to the opposite ends of the installation frame 107. The first louver 203 and the second louver 204 are arranged in the same direction, and a spacer is provided in the middle of the installation frame 107 to separate the cooling ventilation duct and the heating ventilation channel 202. The heating mode and the cooling mode of the present application are adjusted by the opening and closing module, which effectively solves the problem of high resistance along the way caused by the airflow in the traditional heating mode having to pass through the refrigeration core.

[0045] In a specific embodiment, the collecting pipe 101 of the refrigeration core and the heating core is shared, and a partition is provided in the collecting pipe 101 to form a refrigeration chamber of the refrigeration core and a heating chamber of the heating core. Specifically, the collecting pipe 101 can be installed at the end of the installation frame 107, and the side of the installation frame 107 is provided with a plug-in strip and a flat tube 106, the plug-in strip is connected to the refrigeration core, and the flat tube is connected to the heating core. The present application integrates the refrigeration core and the heating core into an integrated design, that is, the originally independent cores are combined into one, and the two cores share the same installation frame 107, which saves volume space to a great extent.

[0046] The heat exchange core 100 further includes a first inlet pipe 102 and a first outlet pipe 103; the first inlet pipe 102 and the first outlet pipe 103 are connected to the refrigeration chamber.

[0047] The heat exchange core 100 further includes a second inlet pipe 104 and a second outlet pipe 105, which are connected to the heating chamber. The first inlet pipe 102, the first outlet pipe 103, the second inlet pipe 104 and the second outlet pipe 105 can be connected in the same manner as the traditional refrigeration core and the heating core.

[0048] like Figure 3 As shown, in a specific embodiment, the ends of the first inlet duct 102, the first outlet duct 103, the second inlet duct 104 and the second outlet duct 105 away from the collecting pipe 101 are located at the air inlet end of the ventilation channel. Specifically, the ends of the first inlet duct 102, the first outlet duct 103, the second inlet duct 104 and the second outlet duct 105 away from the collecting pipe 101 are arranged close to each other to reduce the overall occupation of a large volume. Further, preferably, the first inlet duct 102, the first outlet duct 103, the second inlet duct 104 and the second outlet duct 105 are located as a whole within the peripheral frame range corresponding to the installation frame 107, that is, when installed, the whole is supported by the installation frame 107.

[0049] In a specific embodiment, Figure 5 As shown, the refrigeration chamber is directly opposite to the refrigeration ventilation channel 201, and the heating chamber is directly opposite to the heating ventilation channel 202, that is, the airflow through the refrigeration ventilation channel 201 directly exchanges heat with the medium in the refrigeration chamber, and the airflow through the heating ventilation channel 202 directly exchanges heat with the medium in the heating chamber. This arrangement allows the airflow to exchange heat with the refrigeration chamber or the heating chamber as quickly as possible to improve the heat exchange efficiency.

[0050] In a specific embodiment, Figure 3 As shown, at least one of the first inlet pipe 102, the first outlet pipe 103, the second inlet pipe 104 and the second outlet pipe 105 is arranged at the side of the manifold. The side of the manifold is located between the end of the manifold and the ventilation channel. In this way, the first inlet pipe 102, the first outlet pipe 103, the second inlet pipe 104 and the second outlet pipe 105 are not arranged at the end of the manifold, so that the end of the manifold forms an integral mounting surface, which is convenient for other components to cooperate. Preferably, the first inlet pipe 102, the first outlet pipe 103, the second inlet pipe 104 and the second outlet pipe 105 are all arranged at the side of the manifold.

[0051] During specific assembly, various structures within the heat exchange core 100 of the present application can be connected by welding.

[0052] To facilitate overall disassembly and assembly, preferably, the vehicle air conditioner provided in the present application also includes an air-conditioning box, the heating core is located in the air-conditioning box, the cooling core is located in the air-conditioning box, and the heat exchange group 200 is located in the air-conditioning box.

[0053] This application saves a single core by using a design method that highly integrates the heating core and the cooling core. Based on the current material costs of each part, the mold tooling costs can be saved by about 500,000 yuan; the cost of each piece can be reduced by about 20 to 30 yuan, and the vehicle can save about 50mm of space in the X direction, which is the direction in which the traditional heating core and cooling core are arranged. The platform model can be simplified according to demand so that the same core can be used. Therefore, the design method of highly integrating the heating core and the cooling core for the vehicle air conditioner provided in this application can be applied to models with higher space volume requirements.

[0054] The present application provides a vehicle, including a vehicle body and a vehicle air conditioner installed in the vehicle body, wherein the vehicle air conditioner is any of the above-mentioned vehicle air conditioners. The above-mentioned specific structure of the vehicle air conditioner is described, and the present application includes the above-mentioned vehicle air conditioner, and also has the above-mentioned technical effects.
