[0049] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.

[0050] The following disclosure provides many different embodiments or examples for implementing different structures of the present utility model. To simplify the disclosure of the present utility model, components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present utility model. In addition, the present utility model may repeat reference numerals and / or letters in different examples.

In addition, the present utility model provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0051] Next, with reference to the accompanying drawings, the heat exchange component 1 according to an embodiment of the present utility model will be described.

[0052] As Figures 1 - 11 shown, the heat exchange component 1 according to an embodiment of the present utility model includes: a heat exchanger 11 and an electronic expansion valve 122. At least two independent flow channels are provided in the heat exchanger 11; the electronic expansion valve 122 includes a housing 1221, a valve body 1222, and a coil 1223. The housing 1221 and the valve body 1222 are both installed on the heat exchanger 11. The housing 1221 covers the valve body 1222. The coil 1223 is located outside the housing 1221 and is installed on the housing 1221. The valve body 1222 cooperates with the coil 1223 and is communicated with one of the flow channels.

[0053] Thus, there is no need to additionally provide a refrigerant pipe, which can achieve an integrated design, is beneficial to reducing the space occupied by the heat exchange component 1, and can reduce the processing difficulty and the probability of refrigerant leakage of the heat exchange component 1, improving the reliability of the heat exchange component 1.

[0054] First, as Figures 1 - 2 shown, the heat exchange component 1 includes a heat exchanger 11. At least two independent flow channels are provided in the heat exchanger 11, such as two flow channels, i.e., a first flow channel 111 and a second flow channel 112, or more flow channels. A heat exchange medium flows through each flow channel, and the heat exchange media in different flow channels can exchange heat, but do not flow through each other to achieve independence. For example, the heat exchange medium in at least one flow channel is a refrigerant (i.e., a refrigerant), and exemplarily, the heat exchange medium in each flow channel can be a refrigerant, or exemplarily, the heat exchange medium in one flow channel is a refrigerant, and the heat exchange medium in another flow channel is water or the like.

[0055] Among them, the heat exchange component 1 further includes an electronic expansion valve 122. The electronic expansion valve 122 includes a housing 1221, a valve body 1222, and a coil 1223. Both the housing 1221 and the valve body 1222 are installed on the heat exchanger 11. For example, the housing 1221 and the valve body 1222 can be welded to the heat exchanger 11 respectively. The housing 1221 is used to cover the valve body 1222 to protect the valve body 1222. The coil 1223 is located outside the housing 1221 and installed on the housing 1221. The valve body 1222 cooperates with the coil 1223. The coil 1223 is used to adjust the opening degree of the valve body 1222. The valve body 1222 is used to communicate with one of the flow channels, and the valve body 1222 is used to throttle the refrigerant flowing into the flow channel.

[0056] Specifically, as Figures 6 - 10 shown, the heat exchanger 11 can be set to include a first flow channel 111 and a second flow channel 112. The first flow channel 111 communicates with the outdoor heat exchanger 3 and the indoor heat exchanger 2 respectively. The inlet of the second flow channel 112 is communicated with the first flow channel 111 through the valve body 1222, and the outlet is communicated with the compressor 4.

[0057] As Figure 6 and Figure 9 shown, when the cooling and heating adjustment device 1000 switches to the cooling mode, the compressor 4 can send the compressed refrigerant into the outdoor heat exchanger 3. The compressed refrigerant releases heat in the outdoor heat exchanger 3, and the refrigerant after heat release can flow into the first flow channel 111 of the heat exchanger 11. Part of the refrigerant flowing into the first flow channel 111 can directly flow into the indoor heat exchanger 2 and expand and absorb heat to achieve refrigeration, and then flow back into the compressor 4; another part of the refrigerant flowing into the first flow channel 111 can flow into the second flow channel 112 through the valve body 1222 and expand and absorb heat in the second flow channel 112 to reduce the temperature of the refrigerant in the first flow channel 111 and improve the refrigeration effect of the refrigerant in the indoor heat exchanger 2. The refrigerant flowing into the second flow channel 112 can flow back into the compressor 4 after absorbing heat. The power and the amount of refrigerant flowing back to the compressor 4 can be controlled by controlling the opening degree of the electronic expansion valve 122. The refrigerant is throttled to make the refrigerant become gaseous to prevent liquid hammer, and the compressor 4 is replenished with liquid, so that the compressor 4 can work efficiently.

[0058] As Figure 7 and Figure 10As shown, when the heating and cooling adjustment device 1000 switches to the heating mode, the compressor 4 can send the compressed refrigerant into the indoor heat exchanger 2. The compressed refrigerant releases heat in the indoor heat exchanger 2 to achieve heating. After releasing heat, the refrigerant flows into the first flow channel 111 of the heat exchanger 11. Part of the refrigerant flowing into the first flow channel 111 can flow into the outdoor heat exchanger 3 and expand and absorb heat, and then flow back into the compressor 4 after absorbing heat; another part of the refrigerant flowing into the first flow channel 111 can flow into the second flow channel 112 through the valve body 1222, and expand and absorb heat in the second flow channel 112 to reduce the temperature of the refrigerant in the first flow channel 111 and improve the heat absorption efficiency of the refrigerant in the outdoor heat exchanger 3. The refrigerant flowing into the second flow channel 112 can flow back into the compressor 4 after absorbing heat. The power and the amount of refrigerant flowing back to the compressor 4 can be controlled by controlling the opening degree of the electronic expansion valve 122. The refrigerant is throttled to make the refrigerant become gaseous to prevent liquid hammer, and the compressor 4 is replenished with liquid, so that the compressor 4 can work efficiently.

[0059] It can be understood that by directly installing the electronic expansion valve 122 on the heat exchanger 11, there is no need to additionally arrange a refrigerant pipe to connect the electronic expansion valve 122 and the heat exchanger 11, which can achieve an integrated design, reduce the space occupied by the heat exchange component 1, reduce the processing cost, and since the number of components is reduced, the assembly process of the heat exchange component 1 can be simplified, the processing difficulty is reduced, and the probability of refrigerant leakage can also be reduced.

[0060] In addition, by covering the valve body 1222 with the housing 1221, the valve body 1222 can be protected to improve the operating stability of the valve body 1222. And by locating the coil 1223 outside the housing 1221, the heat dissipation efficiency of the coil 1223 can be ensured, and it is convenient for subsequent maintenance, improving the practicability of the heat exchange component 1.

[0061] According to the heat exchange component 1 of the embodiment of the present utility model, by directly installing the electronic expansion valve 122 on the heat exchanger 11, there is no need to additionally arrange a refrigerant pipe, which can achieve an integrated design, is beneficial to reducing the space occupied by the heat exchange component 1, and can also reduce the processing difficulty of the heat exchange component 1, and can also make the refrigerant not easy to leak, improving the reliability of the heat exchange component 1.

[0062] In some embodiments of the present utility model, as Figures 1 - 2 shown, the electronic expansion valve 122 further includes a mounting member 1224. The coil 1223 is connected to the mounting member 1224, and the mounting member 1224 is connected to the housing 1221, so that the coil 1223 can be mounted on the housing 1221 through the mounting member 1224.

[0063] In the specific installation process, the valve body 1222 can be first welded to the heat exchanger 11, then the housing 1221 is welded to the heat exchanger 11, and then the mounting member 1224 is connected to the coil 1223. Next, the mounting member 1224 is fixed to the housing 1221, and the coil 1223 is connected to the valve body 1222, thereby realizing the installation of the electronic expansion valve 122.

[0064] Through the above settings, the simple installation of the coil 1223 can be realized, and the relative position between the coil 1223 and the housing 1221 can be more easily adjusted, improving the practicability of the heat exchange component 1.

[0065] In some embodiments of the present invention, the mounting member 1224 includes a first connecting portion 12241. The first connecting portion 12241 is disposed on the side of the coil 1223 facing the housing 1221 and is connected to the coil 1223. The valve body 1222 passes through the first connecting portion 12241 to cooperate with the coil 1223.

[0066] For example, as shown in Figures 1 - 3 The mounting member 1224 includes a first connecting portion 12241. The first connecting portion 12241 is disposed on the side of the coil 1223 facing the housing 1221. The first connecting portion 12241 is connected to the coil 1223. The first connecting portion 12241 can be circumferentially attached to the side wall of the coil 1223. The end of the valve body 1222 protrudes from the housing 1221. The valve body 1222 is used to pass through the first connecting portion 12241 to cooperate with the coil 1223 so that the coil 1223 can adjust the opening degree of the valve body 1222.

[0067] Exemplarily, the first connecting portion 12241 can be configured as an annular shape, and the end of the valve body 1222 is matched with the annular hole of the first connecting portion 12241; or, the first connecting portion 12241 can be provided with a notch, and the end of the valve body 1222 is matched with the notch of the first connecting portion 12241. The present application does not limit this.

[0068] Through the above settings, the connection size between the mounting member 1224 and the coil 1223 can be increased, improving the connection stability between the coil 1223 and the mounting member 1224. Moreover, the mounting member 1224 can be used to limit the valve body 1222 to improve the cooperation stability between the valve body 1222 and the coil 1223, and improve the operation stability of the electronic expansion valve 122.

[0069] In some embodiments of the present utility model, a connection hole 12244 is provided on the first connection portion 12241, and the coil 1223 is provided with a connection protrusion 12231. The connection protrusion 12231 includes a first section and a second section. The first section passes through the connection hole 12244, and the diameter of the second section is larger than that of the connection hole 12244, and the second section abuts against the side of the first connection portion 12241 away from the coil 1223.

[0070] For example, with reference to Figures 1 - 3 As shown, a connection hole 12244 can be provided on the first connection portion 12241. The connection hole 12244 penetrates the first connection portion 12241 in the thickness direction. A connection protrusion 12231 is provided on the side of the coil 1223 facing the first connection portion 12241, and the connection protrusion 12231 is arranged corresponding to the connection hole 12244. Among them, the connection protrusion 12231 includes a first section and a second section. The first section and the second section are arranged in sequence along the axial direction. The first section passes through the connection hole 12244, and the second section can penetrate the connection hole 12244 and extend to the side of the first connection portion 12241 away from the coil 1223. The diameter of the second section is larger than that of the connection hole 12244, and the second section can be used for abutting and cooperating with the side of the first connection portion 12241 away from the coil 1223, so as to realize the connection between the coil 1223 and the first connection portion 12241. Specifically, the material of the second section can be taken as an elastic material such as rubber.

[0071] In the specific processing process, it can be set that the diameter of the second section before installation is the same as that of the connection hole 12244. After the second section penetrates the connection hole 12244 and extends to the side of the first connection portion 12241 away from the coil 1223, the second section can be processed, such as pressing the second section from a cylindrical shape into a strip shape, so that the maximum diameter of the second section is larger than that of the connection hole 12244.

[0072] Through the above settings, the installation difficulty of the coil 1223 can be reduced, and the installation stability between the first connection portion 12241 and the coil 1223 can be improved, and the reliability of the electronic expansion valve 122 is improved.

[0073] In some embodiments of the present utility model, such as Figures 2 - 3 As shown, a plurality of connection holes 12244 can be provided. The plurality of connection holes 12244 are arranged at intervals along the circumferential direction of the valve body 1222, and a plurality of connection protrusions 12231 can be provided on the coil 1223. The number of the connection protrusions 12231 is the same as that of the connection holes 12244, and the plurality of connection protrusions 12231 and the plurality of connection holes 12244 are connected in one-to-one correspondence. Thereby, the connection reliability between the first connection portion 12241 and the electronic expansion valve 122 can be improved.

[0074] In some embodiments of the present utility model, as Figures 1 - 3 shown, the mounting member 1224 further includes a positioning portion 12242 which extends from the edge of the first connecting portion 12241 in a direction away from the housing 1221, and the positioning portion 12242 is used for positioning and cooperating with the coil 1223. Thereby, rapid positioning between the mounting member 1224 and the coil 1223 can be achieved, which is conducive to reducing the installation difficulty between the mounting member 1224 and the coil 1223 and improving the installation efficiency.

[0075] In some embodiments of the present utility model, as Figures 1 - 3 shown, the mounting member 1224 includes a second connecting portion 12243 which extends from the edge of the first connecting portion 12241 in a direction towards the housing 1221, the second connecting portion 12243 extends to the side of the housing 1221 away from the heat exchanger 11, and the second connecting portion 12243 is attached to the side of the housing 1221 away from the heat exchanger 11 and connected to the housing 1221.

[0076] Through the above arrangement, the first connecting portion 12241 and the second connecting portion 12243 can be located on different sides of the housing 1221 respectively, so as to avoid interference between the first connecting portion 12241 and the second connecting portion 12243, which is conducive to reducing the installation difficulty of the mounting member 1224 and improving the practicability of the mounting member 1224.

[0077] In some embodiments of the present utility model, as Figures 1 - 3 shown, one end of the second connecting portion 12243 away from the first connecting portion 12241 has a mounting hole 12245, and a threaded hole corresponding to the mounting hole 12245 is provided on the housing 1221. The threaded connecting member 14 can penetrate through the mounting hole 12245 and be screwed and matched with the threaded hole, so as to detachably connect the second connecting portion 12243 with the housing 1221.

[0078] Through the above arrangement, the installation stability of the coil 1223 can be improved, and the coil 1223 can be easily disassembled and assembled, which is beneficial to the subsequent maintenance of the coil 1223 and improves the practicability of the heat exchange component 1.

[0079] In some embodiments of the present utility model, as Figures 1 - 3 shown, the mounting member 1224 further includes a positioning portion 12242 which extends from the first connecting portion 12241 in a direction away from the housing 1221, the positioning portion 12242 is used for positioning and cooperating with the coil 1223 to achieve rapid installation between the coil 1223 and the mounting member 1224, and the positioning portion 12242 and the second connecting portion 12243 are respectively located at two radial ends of the first connecting portion 12241.

[0080] It can be understood that by disposing the positioning portion 12242 and the second connecting portion 12243 at the radial two ends of the first connecting portion 12241 respectively, the processing difficulty of the mounting member 1224 can be reduced, and the stress concentration of the mounting member 1224 can be reduced, thereby improving the structural stability of the mounting member 1224.

[0081] In some embodiments of the present utility model, the housing 1221 and the valve body 1222 can be welded to the heat exchanger 11 separately, and the mounting member 1224 is configured as an integral part, so that the coil 1223 can be directly mounted on the housing 1221 through the mounting member 1224. Thus, the structure of the heat exchange component 1 can be simplified, and the practicability of the heat exchange component 1 can be improved.

[0082] In some embodiments of the present utility model, the heat exchanger 11 is a plate heat exchanger and has a first surface 11a. The electronic expansion valve 122 is disposed on the side where the first surface 11a is located. The axis of the coil 1223 is arranged parallel to the first surface 11a, and the housing 1221 is disposed at one axial end of the coil 1223.

[0083] For example, as shown in Figures 4 - 5 The heat exchanger 11 can be configured as a plate heat exchanger, and one surface of the plate heat exchanger in the thickness direction is set as the first surface 11a. Among them, the electronic expansion valve 122 can be disposed on the side where the first surface 11a is located, and the axis of the coil 1223 is arranged parallel to the first surface 11a, so that the distance between the coil 1223 and the first surface 11a remains uniform, so as to avoid interference between the coil 1223 and the plate heat exchanger. At the same time, the housing 1221 can be disposed at one axial end of the coil 1223, so that the coil 1223 can be directly opposite to the valve body 1222 in the housing 1221, which is convenient for installing the valve body 1222 and the coil 1223.

[0084] Through the above settings, the layout rationality of the heat exchange component 1 can be improved, the processing difficulty of the heat exchange component 1 can be reduced, and the space occupation of the heat exchange component 1 can be reduced.

[0085] In some embodiments of the present utility model, each connecting pipeline communicated with the flow channel is disposed on the first surface 11a, and each connecting pipeline is arranged to avoid the disassembly path of the coil 1223. It should be noted that the coil 1223 is axially inserted and connected to the valve body 1222. During the disassembly and assembly process of the coil 1223, the coil 1223 moves axially relative to the heat exchanger 11 to realize disassembly and assembly, and the disassembly path is the area swept by the coil 1223 moving axially.

[0086] It can be understood that by arranging all the connecting pipelines communicating with the flow channels on the first surface 11a, the space on the heat exchanger 11 can be better utilized, the overall size of the heat exchange component 1 is reduced, and by arranging each connecting pipeline to avoid the area swept by the axial movement of the coil 1223, interference between the coil 1223 and the connecting pipeline during disassembly and assembly can be avoided, facilitating the subsequent maintenance of the electronic expansion valve 122.

[0087] In some embodiments of the present invention, the first surface 11a of the heat exchanger 11 is rectangular and includes four top corners. The first top corner 1171 and the second top corner 1172 among the four top corners are located at both ends of the length of the first surface 11a and are diagonally arranged. The third top corner 1173 and the fourth top corner 1174 are located at both ends of the length of the first surface 11a and are diagonally arranged. The first top corner 1171 and the third top corner 1173 are on the same side of the length of the first surface 11a. The valve body 1222 is connected to the third top corner 1173. The coil 1223 is arranged on one side of the housing 1221 close to the second top corner 1172. The axis of the coil 1223 is inclined to the length direction of the first surface 11a, so that the whole electronic expansion valve 122 is located on the side of the connection line between the first top corner 1171 and the second top corner 1172 away from the fourth top corner 1174.

[0088] For example, as shown in Figures 4 - 5 The first surface 11a of the heat exchanger 11 can be constructed as a rectangle. The first surface 11a of the heat exchanger 11 includes four top corners, which are the first top corner 1171, the second top corner 1172, the third top corner 1173 and the fourth top corner 1174 respectively. The first top corner 1171 and the second top corner 1172 are located at both ends of the length of the first surface 11a and are diagonally arranged. The third top corner 1173 and the fourth top corner 1174 are located at both ends of the length of the first surface 11a and are diagonally arranged. The first top corner 1171 and the third top corner 1173 are on the same side of the length of the first surface 11a. The second top corner 1172 and the fourth top corner 1174 are on the same side of the length of the first surface 11a.

[0089] Among them, the valve body 1222 can be connected to the third top corner 1173, and the coil 1223 is arranged on one side of the housing 1221 close to the second top corner 1172. The axis of the coil 1223 is inclined to the length direction of the first surface 11a and has a certain included angle, so that the whole electronic expansion valve 122 is located on the side of the connection line between the first top corner 1171 and the second top corner 1172 away from the fourth top corner 1174, so that the area where the coil 1223 moves axially is staggered from the second top corner 1172 and the fourth top corner 1174.

[0090] Through the above arrangement, interference between the coil 1223 and the connecting pipeline on the heat exchanger 11 during disassembly and assembly can be prevented, facilitating the subsequent maintenance of the electronic expansion valve 122.

[0091] In some embodiments of the present utility model, as Figure 5 shown, the included angle between the axis of the coil 1223 and the length direction of the first surface 11a may be set as the first included angle α1, and the included angle between the connection line of the first vertex angle 1171 and the second vertex angle 1172 and the length direction of the first surface 11a may be set as the second included angle α2, wherein the first included angle α1 is greater than the second included angle α2. Thus, it can be ensured that the area swept by the coil 1223 moving along the axial direction does not interfere with the connecting pipeline corresponding to the second vertex angle 1172.

[0092] In some embodiments of the present utility model, the first included angle α1 may be set to 10° - 50°. Exemplarily, the first included angle may be taken as 20°; or, the first included angle may be taken as 25°; or, the first included angle may be taken as 30°; or, the first included angle may be taken as 40°, and the present application does not limit this. Thus, it can ensure the convenience of disassembling the coil 122, and can avoid the part of the coil 122 extending outwards being too large, resulting in an over-sized heat exchange component 1, and improving the design rationality of the heat exchange component 1.

[0093] In some embodiments of the present utility model, the electronic expansion valve 122 and the heat exchanger 11 may be integrally connected. The integral connection means non-detachable and fixed into one body, for example, it may be fixed by welding or other means. Thus, it can improve the installation stability of the electronic expansion valve 122 and the reliability of the heat exchange component 1.

[0094] In some embodiments of the present utility model, the heat exchanger 11 is provided with an independent first flow channel 111 and a second flow channel 112; the heat exchanger 11 has a first port 113, a second port 114, a third port 115 and a fourth port 116. The first port 113 and the second port 114 are respectively communicated with both ends of the first flow channel 111, and the third port 115 and the fourth port 116 are respectively communicated with both ends of the second flow channel 112; the heat exchange component 1 further includes a connection device 13. The connection device 13 is installed on the heat exchanger 11 and includes a filter 131 and a connection member 132. The connection member 132 includes a first interface 1321, a second interface 1322 and a third interface 1323 that are pairwise communicated with each other. The first interface 1321 is communicated with the first port 113, the second interface 1322 is communicated with the third port 115 through a throttling device 12, the throttling device 12 includes an electronic expansion valve 122 and an electronic expansion valve 122, and the third interface 1323 is communicated with the filter 131.

[0095] For example, referring to Figure 1 、 Figure 4 and Figures 6 - 10As shown, the heat exchanger 11 is provided with an independent first flow channel 111 and a second flow channel 112 therein. One surface of the heat exchanger 11 in the thickness direction is the first surface 11a. The first surface 11a of the heat exchanger 11 is provided with a first port 113, a second port 114, a third port 115 and a fourth port 116. The first port 113 and the second port 114 are respectively communicated with both ends of the first flow channel 111, and the third port 115 and the fourth port 116 are respectively communicated with both ends of the second flow channel 112.

[0096] Among them, the heat exchange component 1 further includes a connecting device 13. The connecting device 13 is installed on the heat exchanger 11, such as being welded to the heat exchanger 11. The connecting device 13 includes a filter 131 and a connecting member 132. The connecting member 132 is configured as a tube. The connecting member 132 has a first interface 1321, a second interface 1322 and a third interface 1323, and the first interface 1321, the second interface 1322 and the third interface 1323 are communicated with each other in pairs. The first interface 1321 is used to communicate with the first port 113 so that the connecting member 132 and the first flow channel 111 are communicated. The second interface 1322 can be communicated with the third port 115 through a throttling device 12. The throttling device 12 includes a connected capillary throttling element 121 and an electronic expansion valve 122, so that the connecting member 132 can be communicated with the second flow channel 112 through the capillary throttling element 121 and the electronic expansion valve 122. The third interface 1323 is communicated with the filter 131.

[0097] Specifically, the filter 131 can be communicated with the outdoor heat exchanger 3, the second port 114 can be communicated with the indoor heat exchanger 2, and the fourth port 116 can be communicated with the compressor 4.

[0098] When the cooling and heating adjustment device 1000 is switched to the cooling mode, the compressor 4 can send the compressed refrigerant into the outdoor heat exchanger 3. The compressed refrigerant releases heat in the outdoor heat exchanger 3, and the refrigerant after heat release flows through the filter 131 and then flows into the connecting member 132. Part of the refrigerant flowing into the connecting member 132 can flow into the first flow channel 111 through the first interface 1321 and flow into the indoor heat exchanger 2 through the second port 114. The refrigerant flowing into the indoor heat exchanger 2 expands and absorbs heat to achieve refrigeration, and then flows back into the compressor 4; another part of the refrigerant flowing into the connecting member 132 can flow through the second interface 1322, the capillary throttling element 121, the electronic expansion valve 122, and the third port 115 and then flow into the second flow channel 112, and expands and absorbs heat in the second flow channel 112 to reduce the temperature of the refrigerant in the first flow channel 111 and improve the refrigeration effect of the refrigerant in the indoor heat exchanger 2. And the refrigerant in the second flow channel 112 can flow back into the compressor 4 through the fourth port 116 after absorbing heat.

[0099] When the heating and cooling adjustment device 1000 switches to the heating mode, the compressor 4 can send the compressed refrigerant into the indoor heat exchanger 2. The compressed refrigerant releases heat in the indoor heat exchanger 2 to achieve heating. After releasing heat, the refrigerant can flow into the first flow channel 111 of the heat exchanger 11 through the second port 114. Part of the refrigerant flowing into the first flow channel 111 can flow through the filter 131 and then into the outdoor heat exchanger 3. The refrigerant flowing into the outdoor heat exchanger 3 expands and absorbs heat, and after absorbing heat, it flows back into the compressor 4; another part of the refrigerant flowing into the first flow channel 111 can flow through the second interface 1322, the capillary throttling element 121, the electronic expansion valve 122, and the third port 115 and then into the second flow channel 112, and expands and absorbs heat in the second flow channel 112 to lower the temperature of the refrigerant in the first flow channel 111, improving the heat absorption efficiency of the refrigerant in the outdoor heat exchanger 3. Moreover, the refrigerant in the second flow channel 112 can flow back into the compressor 4 through the fourth port 116 after absorbing heat.

[0100] It can be understood that by performing double throttling on the refrigerant flowing to the second flow channel 112 through the capillary throttling element 121 and the electronic expansion valve 122, the temperature of the refrigerant in the first flow channel 111 can be fully reduced, improving the heat absorption efficiency of the refrigerant. And by setting the filter 131, the filter 131 can be used to filter impurities in the refrigerant, which is beneficial to reducing the impurity precipitation in the heat exchanger 11 and improving the reliability of the heat exchange component 1.

[0101] In addition, by separately installing the throttling device 12 and the communication device 13 on the heat exchanger 11, an integrated design can be achieved, which is beneficial to reducing the space occupied by the heat exchange component 1, and can reduce the assembly difficulty of the heat exchange component 1, lower the processing cost, and improve the practicability of the heat exchange component 1.

[0104] Specifically, as Figure 9As shown, when the cooling and heating adjustment device 1000 is switched to the cooling mode, the C valve port and the D valve port are communicated, and the E valve port is communicated with the S valve port. The exhaust port of the compressor 4 can send the compressed refrigerant into the outdoor heat exchanger 3 through the reversing valve 5. The compressed refrigerant releases heat in the outdoor heat exchanger 3, and the refrigerant after heat release flows through the throttling member 6 to flow into the connecting member 132. Part of the refrigerant flowing into the connecting member 132 can flow into the first flow channel 111 through the first interface 1321 and flow into the indoor heat exchanger 2 through the second port 114. The refrigerant flowing into the indoor heat exchanger 2 expands and absorbs heat to achieve refrigeration. The refrigerant after heat absorption can flow to the suction port of the compressor 4 through the reversing valve 5; Another part of the refrigerant flowing into the connecting member 132 can flow through the second interface 1322, the capillary throttling element 121, the electronic expansion valve 122, and the third port 115 to flow into the second flow channel 112, and expand and absorb heat in the second flow channel 112 to lower the temperature of the refrigerant in the first flow channel 111, improving the refrigeration effect of the refrigerant in the indoor heat exchanger 2, and the refrigerant in the second flow channel 112 can flow to the suction port of the compressor 4 through the fourth port 116 after heat absorption.

The compressor 4 can send the compressed refrigerant into the indoor heat exchanger 2 through the reversing valve 5. The compressed refrigerant releases heat in the indoor heat exchanger 2 to achieve heating. The refrigerant after heat release can flow into the first flow channel 111 of the heat exchanger 11 through the second port 114. Part of the refrigerant flowing into the first flow channel 111 can flow into the outdoor heat exchanger 3 through the throttling member 6. The refrigerant flowing into the outdoor heat exchanger 3 expands and absorbs heat, and the refrigerant after heat absorption flows to the suction port of the compressor 4 through the reversing valve 5; Another part of the refrigerant flowing into the first flow channel 111 can flow through the second interface 1322, the capillary throttling element 121, the electronic expansion valve 122, and the third port 115 to flow into the second flow channel 112, and expand and absorb heat in the second flow channel 112 to cool the refrigerant in the first flow channel 111, improving the heat absorption efficiency of the refrigerant in the outdoor heat exchanger 3, and the refrigerant in the second flow channel 112 can flow to the suction port of the compressor 4 through the fourth port 116 after heat absorption.
