DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0040] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear to indicate an orientation or position relationship, they are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship in which the product of the invention is usually placed when used. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0041] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0042] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0043] In the prior art, an independently arranged evaporator and condenser are installed in the distribution box. Both the evaporator and the condenser need to occupy the internal space of the distribution box. The large space occupied increases the volume of the distribution box, which is not conducive to miniaturization and lightweight design. In addition, both the evaporator and the condenser need to be assembled on the distribution box through structural parts, which increases the number of parts and the installation cost.

[0044] In view of this, the designer provides a heat exchange component for automobile air conditioner, which integrates the functions of evaporator and condenser on the heat exchange core 100, so that the heat exchange core 100 can realize the mode switching of cooling and heating, simplify the structure, reduce the volume, reduce the occupied space, and facilitate the lightweight and miniaturized design of the air conditioner box. At the same time, the number of parts is reduced, saving costs.

[0045] Please refer to Figure 1 The present embodiment provides a heat exchange assembly for an automobile air conditioner, comprising a heat exchange core 100, a cooling joint 200 and a heating joint 300. The heat exchange core 100 is provided with a heat exchange channel for the flow of refrigerant. The cooling joint 200 and the heating joint 300 are both connected to the heat exchange core 100 and communicate with the heat exchange channel, and one of the cooling joint 200 and the heating joint 300 can be selectively used in conjunction with the heat exchange core 100.

[0046] As described above, the working mode of the automobile air conditioning heat exchange component provided in this embodiment is as follows:

[0047] In cooling mode, the cooling joint 200 is connected to the heat exchange core 100, and the heat exchange core 100 and the heating joint 300 are disconnected to prevent the refrigerant from leaking from the heating joint 300; similarly, in heating mode, the heating joint 300 is connected to the heat exchange core 100, and the heat exchange core 100 and the cooling joint 200 are disconnected to prevent the refrigerant from leaking from the cooling joint 200. In this way, the heat exchange core 100 has the functions of both an evaporator and a condenser. The heat exchange core 100, the cooling joint 200 and the heating joint 300 cooperate with each other to achieve the adjustment of the cooling and heating modes by switching the refrigerant path. It is flexible and convenient to use and easy to control. Since the evaporator and the condenser are set as an integrated structure, compared with the traditional independent design of the evaporator and the condenser, the number is reduced, which is conducive to the miniaturization and lightweight design of the air-conditioning system and can reduce the cost of parts processing and manufacturing.

[0048] The following embodiments illustrate the detailed structure of the automotive air conditioning heat exchange component provided in the present application by way of examples.

[0049] In this embodiment, optionally, the heat exchange core 100 includes a first water chamber 110, a second water chamber 120, a first flat tube unit 130, and a second flat tube unit 140. The first water chamber 110 and the second water chamber 120 are arranged at intervals relative to each other, and the first water chamber 110 and the second water chamber 120 are arranged in parallel and arranged in a regular manner, which is convenient for subsequent assembly. The first water chamber 110 is provided with two independent first flow channels, each of which extends in the length direction of the first water chamber 110, that is, the two first flow channels are arranged in parallel. The second water chamber 120 is provided with a second flow channel. The first flat tube unit 130 and the second flat tube unit 140 are both installed between the first water chamber 110 and the second water chamber 120. One end of the first flat tube unit 130 and one end of the second flat tube unit 140 are respectively connected to the two first flow channels of the first water chamber 110. The other end of the first flat tube unit 130 and the other end of the second flat tube unit 140 are both connected to the second flow channel of the second water chamber 120. In this way, the two first flow channels, the tube cavity of the first flat tube unit 130 , the tube cavity of the second flat tube unit 140 , and the second flow channel cooperate to define a flow channel of the heat exchange core 100 .

[0050] It should be understood that the first flat tube unit 130 and the second flat tube unit 140 each include a plurality of flat tubes, the plurality of flat tubes of the first flat tube unit 130 are arranged in parallel and spaced apart, and the plurality of flat tubes of the second flat tube unit 140 are arranged in parallel and spaced apart. Through the cooperation of the first water chamber 110, the second water chamber 120, the first flat tube unit 130 and the second flat tube unit 140, the flow path of the refrigerant can be increased, the heat exchange area can be increased, and the heat exchange efficiency can be improved.

[0051] In this embodiment, optionally, the refrigeration joint 200 includes a refrigeration water inlet pipe 210, a refrigeration water outlet pipe 220 and a refrigeration mounting seat 230, one end of the refrigeration water inlet pipe 210 and the refrigeration water outlet pipe 220 are respectively connected to the two first flow channels, and the other ends of the refrigeration water inlet pipe 210 and the refrigeration water outlet pipe 220 are both installed on the refrigeration mounting seat 230. Similarly, the heating joint 300 includes a heating water inlet pipe 310, a heating water outlet pipe 320 and a heating mounting seat 330, one end of the heating water inlet pipe 310 and the heating water outlet pipe 320 are respectively connected to the two first flow channels, and the other ends of the heating water inlet pipe 310 and the heating water outlet pipe 320 are both installed on the heating mounting seat 330. During assembly, the refrigeration joint 200 and the heating joint 300 are both connected to the first water chamber 110, and the two are distributed at both ends of the length direction of the first water chamber 110, and the positions of the two will not interfere with each other, which is convenient for assembly. At the same time, the cooling joint 200 and the heating joint 300 are respectively at the two ends of the first water chamber 110. When the refrigerant flows in the first water chamber 110, it is not easy to accumulate at the end of the first water chamber 110. The refrigerant circulation flows more smoothly, which is beneficial to the operation of the air-conditioning system.

[0052] In addition, by installing the cooling joint 200 and the heating joint 300 on the same side of the heat exchange core 100, the layout is convenient, and the overall structure is more compact and small in size.

[0053] It should be understood that the cooling water inlet pipe 210, the cooling water outlet pipe 220, the heating water inlet pipe 310, and the heating water outlet pipe 320 can be connected to the first water chamber 110 by riveting, welding or screwing, and a seal can be set between each pipe body and the first water chamber 110 to improve the sealing performance.

[0054] The following describes the flow path of the refrigerant in the cooling mode of the automobile air-conditioning heat exchange assembly in the embodiment of the present application.

[0055] The refrigerant enters the flow channel a of the two first flow channels from the cooling water inlet pipe 210 , then enters the second flow channel from the first flat tube unit 130 , then flows into the flow channel b of the two first flow channels from the second flat tube unit, and finally flows out from the cooling water outlet pipe 220 .

[0056] The following describes the flow path of the refrigerant in the heating mode of the automobile air-conditioning heat exchange assembly in the embodiment of the present application.

[0057] The refrigerant enters flow channel a of the two first flow channels from the heating water inlet pipe 310 , then enters the second flow channel from the first flat tube unit 130 , then flows into flow channel b of the two first flow channels from the second flat tube unit 140 , and finally flows out from the heating water outlet pipe 320 .

[0058] The automobile air-conditioning heat exchange assembly provided in this embodiment can not only realize the functions of the evaporator and the condenser through the cooperation of the heat exchange core 100, the refrigeration joint 200 and the heating joint 300, but also reduce the number of parts and the size, which is conducive to lightweight and miniaturized design and low assembly cost.

[0059] Please combine Figure 1 and Figure 2 This embodiment also provides an automobile air-conditioning box 004, which includes a distribution box body 001 and an automobile air-conditioning heat exchange assembly. The heat exchange core 100 of the automobile air-conditioning heat exchange assembly is installed in the distribution box body 001, and can adjust the temperature of the air entering from the air inlet of the distribution box body 001. Since the heat exchange core 100 has the functions of an evaporator and a condenser at the same time, it is only necessary to design a position for installing the heat exchange core 100 in the distribution box body 001, and it is not necessary to design two positions for installing the evaporator and the condenser respectively, which saves installation space, reduces the volume of the distribution box body 001, and thus reduces the volume of the air-conditioning box.

[0060] Please combine Figure 3 and Figure 4This embodiment also provides an automobile air-conditioning system, which includes a compressor 002, an outdoor condenser 003, an automobile air-conditioning box 004, a first three-way connector 005, a second three-way connector 006, a first valve 007, a second valve 008, a third valve 009, a fourth valve 010 and a fifth valve 020.

[0061] The refrigerant outlet of the compressor 002 is connected to the first end of the first three-way joint 005, and the second end of the first three-way joint 005 is connected to the outdoor condenser 003 through the first pipeline 030, and the outdoor condenser 003 is connected to the refrigerant inlet of the refrigeration joint 200 through the second pipeline 040. The third end of the first three-way valve is connected to the refrigerant inlet of the heating joint 300 through the third pipeline 050. At the same time, the first valve 007 is provided on the first pipeline 030, the second valve 008 is provided on the second pipeline 040, and the third valve 009 is provided on the third pipeline 050. The refrigerant inlet of the compressor 002 is connected to the first end of the second three-way valve. The second end of the second three-way valve is connected to the refrigerant outlet of the refrigeration joint 200 through the fourth pipeline 060. The third end of the second three-way valve is connected to the refrigerant outlet of the heating joint 300 through the fifth pipeline 070. At the same time, the fourth valve 010 is provided on the fourth pipeline 060, and the fifth valve 020 is provided on the fifth pipeline 070.

[0062] Among them, the first valve 007, the second valve 008, the third valve 009, the fourth valve 010 and the fifth valve 020 can all be solenoid valves.

[0063] It can be seen from the above description that in the cooling mode, the first valve 007, the second valve 008 and the fourth valve 010 are opened, and the third valve 009 and the fifth valve 020 are closed. The refrigerant compressed by the compressor 002 enters the outdoor condenser 003 from the first three-way joint 005, and then enters the heat exchange core 100 from the refrigerant inlet of the cooling joint 200. The refrigerant absorbs the heat of the air in the external environment and evaporates, thereby achieving cooling; and the refrigerant will not leak from the heating joint 300. In the heating mode, the third valve 009 and the fifth valve 020 are opened, and the first valve 007, the second valve 008 and the fourth valve 010 are closed. The refrigerant compressed by the compressor 002 directly enters the heat exchange core 100 from the refrigerant inlet of the heating joint 300, and the refrigerant condenses and releases heat, so that the temperature of the surrounding air rises, and heating is achieved; and the refrigerant will not leak from the cooling joint 200.

[0064] The automobile air conditioning system provided in this embodiment has a compact structure and a small size, which is conducive to lightweight and miniaturized design.

[0065] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
