Detailed Implementation

[0053] The embodiments of this application are described in detail below. Examples of these 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 with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0054] Hereinafter, with reference to the accompanying drawings, a heat exchange component 1 according to an embodiment of the present application will be described.

[0055] As shown in Figures 1-23, the heat exchange component 1 according to an embodiment of this application includes: a heat exchanger 11 and an external assembly. The heat exchanger 11 has a first flow channel 111 and a second flow channel 112 that are independent of each other. The external assembly is installed on the heat exchanger 11 and includes a connecting device 13 and a throttling device 12. The connecting device 13 includes a first interface 1321, a second interface 1322 and a third interface 1323 that are connected to each other. The first interface 1321 is connected to the first flow channel 111, and the second interface 1322 is connected to the second flow channel 112 through the throttling device 12.

[0056] This allows for integrated design, reducing the space occupied by heat exchange component 1, lowering the processing difficulty of heat exchange component 1, reducing the probability of refrigerant leakage, and improving the reliability of heat exchange component 1.

[0057] First, as shown in Figures 1-5, the heat exchange component 1 includes a heat exchanger 11. The heat exchanger 11 has at least two independent first flow channels 111 and second flow channels 112. Refrigerant flows through the first flow channels 111 and the second flow channels 112 respectively. The refrigerant in different flow channels can exchange heat, but they do not flow into each other to achieve mutual independence.

[0058] The heat exchange component 1 also includes an external assembly, which is installed on the heat exchanger 11. For example, the external assembly can be welded to the heat exchanger 11. The external assembly includes a connecting device 13 and a throttling device 12. The connecting device 13 is tubular and has a first interface 1321, a second interface 1322 and a third interface 1323. The first interface 1321, the second interface 1322 and the third interface 1323 are connected to each other in pairs. The first interface 1321 is used to connect with the first flow channel 111, and the second interface 1322 can be connected with the second flow channel 112 through the throttling device 12.

[0059] For example, the third interface 1323 can be connected to the outdoor heat exchanger 3, the first flow channel 111 can be connected to the indoor heat exchanger 2, and the second flow channel 112 can be connected to the compressor 4.

[0060] As shown in Figure 4, when the heating and cooling regulating device 1000 switches to 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 releasing heat can flow into the connecting device 13 through the third interface 1323. Part of the refrigerant flowing into the connecting device 13 can flow into the first flow channel 111 through the first interface 1321 and flow into the indoor heat exchanger 2 along the first flow channel 111. The refrigerant expands and absorbs heat in the indoor heat exchanger 2 to achieve cooling. The refrigerant after absorbing heat can flow back into the compressor 4. Another part of the refrigerant flowing into the connecting device 13 can flow into the second flow channel 112 through the throttling device 12, and expand and absorb heat in the second flow channel 112 to reduce the temperature of the refrigerant in the first flow channel 111, improve the cooling 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 after absorbing heat.

[0061] As shown in Figure 5, when the heating and cooling regulating device 1000 switches to 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 the heating function. The refrigerant after releasing heat flows into the connecting device 13 along the first flow channel 111. Part of the refrigerant flowing into the connecting device 13 can flow into the outdoor heat exchanger 3 through the third interface 1323 and expand to absorb heat, so as to flow back into the compressor 4 after absorbing heat. Another part of the refrigerant flowing into the connecting device 13 can flow into the second flow channel 112 through the throttling device 12 and expand to absorb heat in the second flow channel 112 to reduce the temperature of the refrigerant in the first flow channel 111, improve the heat absorption efficiency of the refrigerant in the outdoor heat exchanger 3, and the refrigerant flowing into the second flow channel 112 can flow back into the compressor 4 after absorbing heat.

[0062] Understandably, by directly mounting the external components onto the heat exchanger 11, there is no need to install additional refrigerant pipes to connect the external components and the heat exchanger 11. This enables an integrated design, reduces the space occupied by the heat exchange components 1, lowers processing costs, and simplifies the installation process of the heat exchange components 1 due to the reduced number of parts. It also reduces the probability of refrigerant leakage.

[0063] According to the embodiments of this application, the heat exchange component 1 can be integrated by directly installing the external components on the heat exchanger 11 without the need for additional refrigerant pipes. This reduces the space occupied by the heat exchange component 1, lowers the processing difficulty of the heat exchange component 1, reduces the probability of refrigerant leakage, and improves the reliability of the heat exchange component 1.

[0064] In some embodiments of this application, as shown in FIG2, the throttling device 12 includes a capillary throttling element 121 and an electronic expansion valve 122, which are sequentially arranged in the direction from the second interface 1322 to the second flow channel 112. Specifically, the second interface 1322, the capillary throttling element 121, the electronic expansion valve 122, and the second flow channel 112 can be sequentially connected; or, the second interface 1322, the electronic expansion valve 122, the capillary throttling element 121, and the second flow channel 112 can be sequentially connected, and this application does not limit this. Thus, the refrigerant flowing to the second flow channel 112 can be doubly throttled, ensuring the throttling effect of the throttling device 12.

[0065] In some embodiments of this application, the capillary throttling element 121, the connecting device 13, and the heat exchanger 11 can be integrated into one unit. This integrated connection means that they are non-removable and fixed together, for example, by welding. This improves the installation stability of the throttling device 12 and enhances the reliability of the heat exchange component 1.

[0066] In some embodiments of this application, the capillary throttling element 121 includes a sleeve portion 1211 and a cylindrical portion 1212. The sleeve portion 1211 is sleeved on the outside of the cylindrical portion 1212 to form a throttling channel between the sleeve portion 1211 and the cylindrical portion 1212. The sleeve portion 1211 is installed on the heat exchanger 11. The cylindrical wall of the sleeve portion 1211 has a first through hole 12111 and a second through hole 12112 that are connected to the throttling channel and are spaced apart along the axial direction. The opening area of ​​the first through hole 12111 is larger than the opening area of ​​the second through hole 12112. The first through hole 12111 is connected to the second interface 1322, and the second through hole 12112 is connected to the electronic expansion valve 122.

[0067] For example, referring to Figures 6-9, the capillary flow element 121 includes a sleeve portion 1211 and a cylindrical portion 1212. The sleeve portion 1211 and the cylindrical portion 1212 are matched and disposed. The sleeve portion 1211 is sleeved on the outside of the cylindrical portion 1212, and a throttling channel is formed between the inner wall of the sleeve portion 1211 and the outer wall of the cylindrical portion 1212.

[0068] The sleeve portion 1211 has a first through hole 12111 and a second through hole 12112 on its cylindrical wall. The first through hole 12111 and the second through hole 12112 are spaced apart along the axial direction of the sleeve portion 1211, so that the first through hole 12111 and the second through hole 12112 can be located at both ends of the throttling channel and are both connected to the throttling channel. The first through hole 12111 is used to communicate with the second interface 1322, so that the refrigerant in the communication device 13 can flow into the throttling channel through the first through hole 12111. The second through hole 12112 is used to communicate with the electronic expansion valve 122, so that the refrigerant in the throttling channel can flow into the electronic expansion valve 122 through the second through hole 12112 and into the second flow channel 112 through the electronic expansion valve 122.

[0069] Specifically, the opening area of ​​the first perforation 12111 can be set to be larger than the opening area of ​​the second perforation 12112, so that the flow area between the connecting device 13 and the throttling channel is larger than the flow area between the electronic expansion valve 122 and the throttling channel.

[0070] Understandably, by setting the throttling channel to be jointly defined by the sleeve portion 1211 and the cylindrical portion 1212, the molding difficulty of the throttling channel can be reduced, improving the practicality of the capillary throttling element 121. Furthermore, by opening the first perforation 12111 and the second perforation 12112 on the cylindrical wall of the sleeve portion 1211, the processing difficulty of the first perforation 12111 and the second perforation 12112 can be reduced, thus reducing the overall processing difficulty of the capillary throttling element 121. Moreover, by setting the opening area of ​​the first perforation 12111 to be larger than the opening area of ​​the second perforation 12112, the flow stability of the refrigerant can be improved, ensuring the throttling effect to a certain extent.

[0071] In some embodiments of this application, referring to Figures 6-9, the inner peripheral wall of the sleeve portion 1211 and / or the outer peripheral wall of the cylindrical portion 1212 are provided with ribs 1213, which participate in defining the throttling channel. Specifically, ribs 1213 may be provided on the inner peripheral wall of the sleeve portion 1211; or, ribs 1213 may be provided on the outer peripheral wall of the cylindrical portion 1212; or, ribs 1213 may be provided on both the inner peripheral wall of the sleeve portion 1211 and the outer peripheral wall of the cylindrical portion 1212, and this application does not limit this. A fitting gap exists between the inner peripheral wall of the sleeve portion 1211 and the outer peripheral wall of the cylindrical portion 1212, and the ribs 1213 can separate the fitting gap to define the throttling channel.

[0072] The above settings can reduce the molding difficulty of the throttling channel, which helps to reduce the overall processing difficulty of the capillary infiltration element 121 and improves the practicality of the capillary infiltration element 121.

[0073] In some embodiments of this application, as shown in Figures 6-9, the rib 1213 can be constructed as a spiral rib coiled around the central axis of the column portion 1212, so that the throttling channel can be formed in a spiral shape. This maximizes the utilization of the space of the capillary throttling element 121, extends the length of the throttling channel, and improves the throttling effect of the capillary throttling element 121.

[0074] In some embodiments of this application, as shown in Figures 6-9, the sleeve portion 1211 can be constructed as a sleeve with an inner circumferential wall of equal diameter, and the cylindrical portion 1212 can be constructed as a cylindrical body with an outer circumferential wall of equal diameter. This configuration ensures the overall uniformity of the throttling channel, improves the throttling effect of the capillary deflection element 121, reduces the processing difficulty of the capillary deflection element 121, and enhances the practicality of the heat exchange component 1.

[0075] Of course, this application is not limited to this. The sleeve portion 1211 can also be constructed as a sleeve with a gradually decreasing diameter, and the cylindrical portion 1212 can be constructed as a cylindrical body with a gradually decreasing diameter. This facilitates the positioning between the sleeve portion 1211 and the cylindrical portion 1212, and reduces the processing difficulty of the capillary flow element 121.

[0076] In some embodiments of this application, as shown in Figures 6-9, the line connecting the center of the first perforation 12111 and the center of the second perforation 12112 can be set parallel to the central axis of the sleeve portion 1211. This arrangement allows the first perforation 12111 and the second perforation 12112 to be located on the same side of the sleeve portion 1211, which helps reduce the layout difficulty of the capillary flow element 121 and improves the practicality of the capillary flow element 121.

[0077] In some embodiments of this application, as shown in Figures 6-9, a stop portion 1214 may be provided at one axial end of the cylindrical portion 1212. The stop portion 1214 is annular and protrudes outward radially from the cylindrical portion 1212. The stop portion 1214 is used to stop outside the shaft end of the sleeve portion 1211 to achieve positioning between the sleeve portion 1211 and the cylindrical portion 1212. The stop portion 1214 can also be used to cover the shaft end of the sleeve portion 1211 to close the fitting clearance between the sleeve portion 1211 and the cylindrical portion 1212. It should be noted that the shaft end of the sleeve portion 1211 away from the stop portion 1214 can be sealed with sealant.

[0078] The above settings can reduce the processing difficulty of the capillary infiltration element 121, improve the structural stability of the capillary infiltration element 121, and improve the reliability of the capillary infiltration element 121.

[0079] In some embodiments of this application, as shown in Figures 6-9, the stop portion 1214 and the column portion 1212 are constructed as a single unit. The sleeve portion 1211 can be fixed to the column portion 1212 by welding the stop portion 1214 to the sleeve portion 1211. This arrangement reduces the difficulty of connecting the sleeve portion 1211 and the column portion 1212, improves the connection stability between them, and ensures the overall reliability of the capillary flow element 121.

[0080] In some embodiments of this application, 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 and the capillary flow element 121. 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 communicates with the second flow channel 112.

[0081] For example, referring to Figures 1, 2, and 13, 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 mounted on the heat exchanger 11. Alternatively, the housing 1221 and the valve body 1222 can be welded to the heat exchanger 11 respectively. The valve body 1222 and the capillary flow element 121 are positioned close to each other, and the housing 1221 is used to cover and protect the valve body 1222 and the capillary flow element 121.

[0082] The coil 1223 is located outside the housing 1221 and is mounted on the housing 1221. The valve body 1222 cooperates with the coil 1223 to adjust the opening of the valve body 1222. The capillary flow element 121 is connected to the connecting device 13 and the electronic expansion valve 122 respectively. The valve body 1222 is connected to the second flow channel 112. The coil 1223 is used to adjust the valve body 1222 to adjust the flow rate of refrigerant when it flows from the capillary flow element 121 into the second flow channel 112.

[0083] The above settings can improve the working stability of the valve body 1222 and the capillary throttling element 121, improve the reliability of the throttling device 12, and when the coil 1223 fails, the coil 1223 can be quickly disassembled from the outside of the housing 1221, which helps to reduce the maintenance difficulty of the throttling device 12 and improves the practicality of the heat exchange component 1.

[0084] In some embodiments of this application, the capillary flow element 121, the connecting device 13, the valve body 1222, and the heat exchanger 11 can be integrated into one unit. This integrated connection means that they are non-removable and fixed as a single unit, for example, by welding. This improves the overall stability and reliability of the heat exchange component 1.

[0085] In some embodiments of this application, as shown in Figures 1, 2 and 13, the electronic expansion valve 122 further includes a mounting member 1224, a 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.

[0086] In the specific installation process, the valve body 1222 can be welded to the heat exchanger 11 first, and then the housing 1221 can be welded to the heat exchanger 11. Then, the mounting part 1224 is connected to the coil 1223, and the mounting part 1224 is fixed to the housing 1221. The coil 1223 is then connected to the valve body 1222, thereby realizing the installation of the electronic expansion valve 122.

[0087] The above settings enable easy installation of coil 1223 and make it easier to adjust the relative position between coil 1223 and housing 1221, thereby improving the practicality of heat exchange component 1.

[0088] In some embodiments of this application, the mounting component 1224 includes a first connecting portion 12241, which is located on the side of the coil 1223 facing the housing 1221 and connected to the coil 1223. The first connecting portion 12241 is annular, and the valve body 1222 passes through the annular hole of the first connecting portion 12241 to cooperate with the coil 1223.

[0089] For example, as shown in Figures 1, 2, and 13, the mounting component 1224 includes a first connecting portion 12241, which is located on the side of the coil 1223 facing the housing 1221. The first connecting portion 12241 is connected to the coil 1223 and is annular in shape, allowing it to circumferentially fit against the side wall of the coil 1223. The end of the valve body 1222 protrudes from the housing 1221 and matches the annular hole of the first connecting portion 12241. The valve body 1222 passes through the annular hole of the first connecting portion 12241 to engage with the coil 1223, allowing the coil 1223 to adjust the opening degree of the valve body 1222.

[0090] The above settings can increase the connection size between the mounting part 1224 and the coil 1223, improve the connection stability between the coil 1223 and the mounting part 1224, and the mounting part 1224 can be used to limit the valve body 1222, thereby improving the coordination stability between the valve body 1222 and the coil 1223 and improving the operation stability of the electronic expansion valve 122.

[0091] In some embodiments of this application, the first connecting portion 12241 is provided with a connecting hole 12244, and the coil 1223 is provided with a connecting protrusion 12231. The connecting protrusion 12231 includes a first segment and a second segment. The first segment passes through the connecting hole 12244, the diameter of the second segment is larger than the diameter of the connecting hole 12244, and the second segment stops on the side of the first connecting portion 12241 away from the coil 1223.

[0092] For example, referring to Figures 1, 2, and 13, a connecting hole 12244 can be provided on the first connecting portion 12241. The connecting hole 12244 penetrates the first connecting portion 12241 along its thickness direction. A connecting protrusion 12231 is provided on the side of the coil 1223 facing the first connecting portion 12241, and the connecting protrusion 12231 is correspondingly provided with the connecting hole 12244. The connecting protrusion 12231 includes a first segment and a second segment, which are arranged sequentially along the axial direction. The first segment passes through the connecting hole 12244, and the second segment can penetrate the connecting hole 12244 and extend to the side of the first connecting portion 12241 away from the coil 1223. The diameter of the second segment is larger than the diameter of the connecting hole 12244. The second segment can be used to stop and cooperate with the side of the first connecting portion 12241 away from the coil 1223, thereby realizing the connection between the coil 1223 and the first connecting portion 12241. Specifically, the material of the second section can be an elastic material such as rubber.

[0093] In the specific processing, the diameter of the second section before installation can be set to be the same as the diameter of the connecting hole 12244. After the second section passes through the connecting hole 12244 and extends to the side of the first connecting part 12241 away from the coil 1223, the second section can be processed, such as pressing the second section from a cylindrical shape into a long strip shape, so that the maximum diameter of the second section is greater than the diameter of the connecting hole 12244.

[0094] The above settings can reduce the installation difficulty of coil 1223, improve the installation stability between the first connection part 12241 and coil 1223, and improve the reliability of electronic expansion valve 122.

[0095] In some embodiments of this application, referring to Figures 1, 2, and 13, multiple connecting holes 12244 can be provided, spaced apart circumferentially along the annular hole. Multiple connecting protrusions 12231 can be provided on the coil 1223, with the number of protrusions 12231 matching the number of connecting holes 12244. These protrusions and holes are connected in a one-to-one correspondence. This improves the reliability of the connection between the first connecting portion 12241 and the coil 1223.

[0096] In some embodiments of this application, referring to Figures 1, 2, and 13, the mounting member 1224 further includes a positioning portion 12242. The positioning portion 12242 extends from the edge of the first connecting portion 12241 toward a direction away from the housing 1221, and is used for positioning and engaging with the coil 1223. This allows for rapid positioning between the mounting member 1224 and the coil 1223, reducing the difficulty of installation and improving installation efficiency.

[0097] In some embodiments of this application, referring to Figures 1, 2 and 13, the mounting member 1224 includes a second connecting portion 12243, which extends from the edge of the first connecting portion 12241 toward the housing 1221. The second connecting portion 12243 extends to the side of the housing 1221 away from the heat exchanger 11, and is attached to the side of the housing 1221 away from the heat exchanger 11 and connected to the housing 1221.

[0098] With the above arrangement, the first connecting part 12241 and the second connecting part 12243 can be located on different sides of the housing 1221, so as to avoid mutual interference between the first connecting part 12241 and the second connecting part 12243, which helps to reduce the installation difficulty of the mounting part 1224 and improves the practicality of the mounting part 1224.

[0099] In some embodiments of this application, as shown in Figures 1, 2 and 13, the end of the second connecting part 12243 away from the first connecting part 12241 has a mounting hole 12245, and the housing 1221 has a threaded hole corresponding to the mounting hole 12245. The threaded connector 14 can pass through the mounting hole 12245 and be screwed into the threaded hole to detachably connect the second connecting part 12243 to the housing 1221.

[0100] The above settings can improve the installation stability of coil 1223, make coil 1223 easy to disassemble and assemble, facilitate subsequent maintenance of coil 1223, and improve the practicality of heat exchange component 1.

[0101] In some embodiments of this application, as shown in Figures 1, 2 and 13, the mounting member 1224 further includes a positioning part 12242. The positioning part 12242 extends from the first connecting part 12241 toward a direction away from the housing 1221. The positioning part 12242 is used to position and cooperate with the coil 1223 to realize the quick installation between the coil 1223 and the mounting member 1224. The positioning part 12242 and the second connecting part 12243 are respectively located at the radial ends of the first connecting part 12241.

[0102] It is understandable that by placing the positioning part 12242 and the second connecting part 12243 at the radial ends of the first connecting part 12241, the processing difficulty of the mounting part 1224 can be reduced, the stress concentration of the mounting part 1224 can be reduced, and the structural stability of the mounting part 1224 can be improved.

[0103] In some embodiments of this application, the housing 1221 and the valve body 1222 can be separately welded to the heat exchanger 11, and the mounting member 1224 can be constructed as a single piece, so that the coil 1223 can be directly mounted to the housing 1221 through the mounting member 1224. This simplifies the structure of the heat exchange component 1 and improves its practicality.

[0104] In some embodiments of this application, as shown in Figures 2 and 13, the heat exchange component 1 of this application embodiment further includes a temperature sensing device 15, which is installed on the throttling device 12. The temperature sensing device 15 is used to detect the temperature of the refrigerant in the throttling device 12 to determine the operating state of the throttling device 12. This allows for real-time monitoring of the heat exchange component 1, which helps ensure its reliability.

[0105] In some embodiments of this application, the temperature sensing device 15 and the throttling device 12 can be integrated into one unit. This integrated connection means that they are not detachable and are fixed together, for example, by welding. This makes it less likely for the temperature sensing device 15 to detach from the throttling device 12, thus improving the operational reliability of the temperature sensing device 15.

[0106] In some other embodiments of this application, the temperature sensing device 15 can be detachably connected to the throttling device 12. Therefore, when the temperature sensing device 15 malfunctions, it can be removed from the throttling device 12 for convenient replacement and easier subsequent maintenance.

[0107] In some embodiments of this application, as shown in Figures 2 and 13, the throttling device 12 includes an electronic expansion valve 122. The valve body 1222 of the electronic expansion valve 122 has a threaded hole. The temperature sensing device 15 includes a threaded portion 151 and a temperature sensing portion 152. The threaded portion 151 is cylindrical and is matched with the threaded hole. The threaded portion 151 is used to extend into and connect with the threaded hole, so as to detachably install the temperature sensing device 15 onto the electronic expansion valve 122. The temperature sensing portion 152 is located at the axial end of the threaded portion 151. When the threaded portion 151 is connected to the threaded hole, the temperature sensing portion 152 can extend into the valve body 1222 through the threaded hole to contact the refrigerant inside the valve body 1222, thereby detecting the temperature of the refrigerant.

[0108] The above-mentioned configuration makes the temperature sensing device 15 easy to disassemble and install, facilitates subsequent maintenance of the temperature sensing device 15, and ensures a good sealing effect between the temperature sensing device 15 and the electronic expansion valve 122, preventing refrigerant leakage and improving the reliability of the heat exchange component 1.

[0109] In some embodiments of this application, as shown in Figures 2 and 13, the temperature sensing device 15 further includes a sealing gasket 153. The sealing gasket 153 can be made of elastic materials such as rubber or sealing foam. The sealing gasket 153 is ring-shaped and is used to fit around the outside of the threaded portion 151 and is located on the side of the threaded portion 151 away from the temperature sensing portion 152. When the threaded portion 151 extends into the threaded hole, the sealing gasket 153 can be sandwiched between the outer wall of the valve body 1222 and the temperature sensing device 15 to seal the mating gap between the threaded hole and the threaded portion 151. This prevents refrigerant leakage and improves the reliability of the heat exchange component 1.

[0110] In some embodiments of this application, as shown in FIG2, the connecting device 13 includes a filter 131 and a connecting member 132. The connecting member 132 is tubular and includes a first interface 1321, a second interface 1322, and a third interface 1323. The connecting member 132 is installed on the heat exchanger 11, such as by welding, snap-fitting, or screwing it onto the heat exchanger 11. The filter 131 is installed on the connecting member 132 and communicates with the third interface 1323. The filter 131 is used to filter the refrigerant flowing into or out of the connecting member 132. This reduces impurities in the refrigerant, helps eliminate the adverse effects caused by impurity accumulation, and improves the reliability of the heat exchange component 1.

[0111] In some embodiments of this application, as shown in FIG2, the heat exchange component 1 according to the embodiment of this application further includes an external pipe 18. The external pipe 18 and the connecting member 132 are respectively connected to both sides of the filter 131. The external pipe 18 is used to connect the connecting member 132 to the outdoor heat exchanger 3 described below. This reduces the installation difficulty of the connecting device 13.

[0112] Furthermore, the external pipe 18, filter 131, and connecting member 132 can be integrated into a single unit. This integrated connection means that they are non-removable and fixed together, for example, by welding. This improves the structural stability and reliability of the heat exchange component 1.

[0113] In some embodiments of this application, the heat exchanger 11 is a plate heat exchanger and has a first surface 11a. An external assembly is disposed on the side where the first surface 11a is located. The connecting member 132 is a three-way valve and includes a vertical pipe section 1324 disposed perpendicular to the first surface 11a and a horizontal pipe section 1325 disposed parallel to the first surface 11a. The end of the vertical pipe section 1324 near the first surface 11a defines a first interface 1321 and is installed on the first surface 11a. The horizontal pipe section 1325 is connected to the side of the vertical pipe section 1324 away from the first surface 11a. The filter 131 includes a tubular shell 1311 and a filter element 1312 installed in the tubular shell 1311. The tubular shell 1311 is disposed perpendicular to the first surface 11a and is located on the side of the horizontal pipe section 1325 away from the vertical pipe section 1324. The end of the tubular shell 1311 near the first surface 11a is connected to the horizontal pipe section 1325.

[0114] For example, referring to Figures 1-3 and Figure 13, the heat exchanger 11 is constructed as a plate heat exchanger. The plate heat exchanger has a first surface 11a on one side along the thickness direction, and the external assembly is located on the side where the first surface 11a is located. The connecting member 132 is constructed as a three-way valve. The connecting member 132 includes a vertical pipe section 1324 and a horizontal pipe section 1325. The vertical pipe section 1324 is arranged perpendicular to the first surface 11a, and the horizontal pipe section 1325 is arranged parallel to the first surface 11a and connected to the horizontal pipe section 1325.

[0115] One end of the vertical pipe section 1324 near the first surface 11a is mounted on the first surface 11a. The end of the vertical pipe section 1324 near the first surface 11a defines a first interface 1321. The first interface 1321 is correspondingly connected to the end of the first flow channel 111 (i.e., the first port 113 below). The horizontal pipe section 1325 is connected to the side of the vertical pipe section 1324 away from the first surface 11a and is connected to the vertical pipe section 1324. The horizontal pipe section 1325 defines a second interface 1322 and a third interface 1323, which are spaced apart.

[0116] The filter 131 includes a tubular shell 1311 and a filter element 1312. The tubular shell 1311 forms a filter channel 1313, and the filter element 1312 is installed in the filter channel 1313. The filter element 1312 is used to filter impurities in the refrigerant. The tubular shell 1311 is arranged perpendicular to the first surface 11a and is located on the side of the horizontal pipe section 1325 away from the vertical pipe section 1324. The end of the tubular shell 1311 near the first surface 11a is connected to the third interface 1323 defined by the horizontal pipe section 1325, and the second interface 1322 is connected to the throttling device 12.

[0117] Understandably, by setting the horizontal pipe section 1325, the connecting part 132 can have a larger installation area, reducing the installation difficulty of the connecting part 132. It can also keep the first interface 1321, the second interface 1322 and the third interface 1323 at a certain distance, which helps to eliminate turbulence, improves the flow stability of the refrigerant and reduces noise.

[0118] In some embodiments of this application, as shown in FIG13, the tubular shell 1311 has an enlarged diameter section 13113, which means that the inner diameter of this section is larger than the inner diameter of the adjacent section, and the filter element 1312 is disposed within the enlarged diameter section 13113. This arrangement makes it easier to position and install the filter element 1312, reduces the assembly difficulty of the filter 131, and reduces flow resistance, thereby increasing the flow velocity of the refrigerant.

[0119] In some embodiments of this application, as shown in FIG13, the filter element 1312 includes a mounting portion 13121 and a filter screen portion 13122. Filter holes are formed on the filter screen portion 13122. The mounting portion 13121 is located at the edge of the filter screen portion 13122 and is used to connect with the tubular shell 1311 to fix the filter element 1312 on the tubular shell 1311. Thus, stable installation of the filter element 1312 can be achieved.

[0120] In some embodiments of this application, the filter portion 13122 is formed as a cylindrical shape with one end closed in the axial direction and the other end open in the axial direction. The area of ​​the closed end of the filter portion 13122 is smaller than the area of ​​the open end of the filter portion 13122, and the mounting portion 13121 is connected to the open end.

[0121] For example, referring to FIG13, the filter portion 13122 is recessed from the edge to the center to form a cylindrical shape. One end of the filter portion 13122 is closed along the axial direction, and the other end is open. The area of ​​the closed end of the filter portion 13122 is smaller than the area of ​​the open end of the filter portion 13122. The closed end and the open end can be smoothly connected by sidewalls so that the diameter of the filter portion 13122 gradually decreases from the closed end to the open end. At the same time, the mounting portion 13121 can be connected to the open end so that the mounting portion 13121 is provided at the edge of the filter portion 13122.

[0122] Specifically, the closed end of the filter section 13122 can be constructed as an endpoint; or, the closed end of the filter section 13122 can be constructed as an end face, and this application does not limit this.

[0123] Understandably, by constructing the filter section 13122 in a cylindrical shape, the flow area of ​​the filter section 13122 can be increased, so that the refrigerant can flow better through the filter section 13122, which helps to reduce flow resistance. Furthermore, by placing the mounting section 13121 at the open end, the overlap between the mounting section 13121 and the filter section 13122 can be reduced, further reducing flow resistance, improving the flow stability of the refrigerant, and improving the practicality of the filter 131.

[0124] In some embodiments of this application, the mounting portion 13121 may be configured to have an interference fit with the inner peripheral wall of the tubular shell 1311. This improves the installation stability of the filter element 1312, reduces the installation difficulty of the filter element 1312, and enhances the reliability of the filter 131.

[0125] In some embodiments of this application, as shown in FIG13, the mounting portion 13121 and the filter portion 13122 are arranged sequentially along the axial direction of the tubular shell 1311. A retaining rib 13114 protrudes from the inner peripheral wall of the tubular shell 1311, and the retaining rib 13114 is engaged with the mounting portion 13121 on the side near the filter portion 13122. Thus, when the filter portion 13122 is subjected to refrigerant impact and tends to move away from the mounting portion 13121, the retaining rib 13114 can limit the mounting portion 13121, preventing the filter element 1312 from moving within the expanded diameter section 13113. This improves the overall stability of the filter 131.

[0126] Of course, the locking rib 13114 can also be locked on the side of the mounting part 13121 away from the filter part 13122; or, two locking ribs can be set, with the two locking ribs 13114 respectively locked on both sides of the mounting part 13121. This application does not limit this.

[0127] In some embodiments of this application, the tubular shell 1311 includes a first shell portion 13111 and a second shell portion 13112 connected along the axial direction, and the mounting portion 13121 is sandwiched between the first shell portion 13111 and the second shell portion 13112.

[0128] For example, referring to FIG13, the tubular shell 1311 includes a first shell portion 13111 and a second shell portion 13112. The first shell portion 13111 and the second shell portion 13112 are separately formed. The first shell portion 13111 and the second shell portion 13112 are arranged sequentially along the axial direction and are adapted to be connected to form the tubular shell 1311. The mounting portion 13121 is provided to protrude radially outward and is sandwiched between the first shell portion 13111 and the second shell portion 13112 to limit and fit with the tubular shell 1311 along the axial direction. As a result, the installation stability of the filter element 1312 can be improved.

[0129] In some embodiments of this application, the first shell portion 13111 has a first end portion 13111a, the second shell portion 13112 has a second end portion 13112a, the first end portion 13111a is covered over the second end portion 13112a, the filter portion 13122 is disposed inside the second shell portion 13112, and at least a portion of the mounting portion 13121 extends over the second end portion 13112a to be sandwiched between the first end portion 13111a and the second end portion 13112a.

[0130] For example, referring to FIG13, the end of the first shell portion 13111 facing the second shell portion 13112 can be designated as the first end portion 13111a, and the end of the second shell portion 13112 facing the first shell portion 13111 can be designated as the second end portion 13112a. The inner diameter of the first end portion 13111a matches the outer diameter of the second end portion 13112a, so that the first end portion 13111a of the first shell portion 13111 can cover the second end portion 13112a of the second shell portion 13112.

[0131] The filter element 13122 can be disposed within the second housing portion 13112, and at least a portion of the mounting portion 13121 can extend to the outside of the second end portion 13112a, so that the mounting portion 13121 can be clamped between the first end portion 13111a and the second end portion 13112a to fix it to the tubular housing 1311. This improves the installation stability of the filter element 1312 and enhances the reliability of the filter 131.

[0132] In some embodiments of this application, as shown in FIG13, multiple mounting portions 13121 can be provided, with the multiple mounting portions 13121 spaced apart circumferentially along the filter portion 13122 and respectively cooperating with the tubular shell 1311. This improves the installation stability of the filter element 1312.

[0133] In some embodiments of this application, as shown in FIG2, the heat exchanger 11 is a plate heat exchanger. The plate heat exchanger has a first surface 11a on one side along the thickness direction. The filter 131 is disposed on the side where the first surface 11a is located. The axial direction of the tubular shell 1311 is perpendicular to the first surface 11a, and one end of the axial direction is connected to the heat exchanger 11. Through the above arrangement, the filter 131 can be more easily positioned and installed, which helps to reduce the processing difficulty of the heat exchange component 1 and improves the practicality of the heat exchange component 1.

[0134] In some embodiments of this application, as shown in FIG14, filter 131 includes a first filter 131a and a second filter 131b. The first filter 131a is installed in heat exchanger 11 and communicates with the first flow channel 111. The first filter 131a is used to filter the refrigerant flowing into or out of the first flow channel 111. The second filter 131b is installed in heat exchanger 11 and communicates with the second flow channel 112. The second filter 131b is used to filter the refrigerant flowing into or out of the second flow channel 112.

[0135] With the above settings, the refrigerant in the first flow channel 111 and the second flow channel 112 can be filtered in a targeted manner, which helps to improve the filtration effect of the filter 131 and reduce the accumulation of impurities.

[0136] In some embodiments of this application, the first surface 11a is rectangular, and the two vertices on the same side of the length direction are a first vertices 1171 and a third vertices 1173, respectively. The two vertices on the other side of the length direction are a second vertices 1172 and a fourth vertices 1174, which are diagonally opposite to the first vertices 1171 and the third vertices 1173, respectively. A first connecting pipe 16 communicating with the first flow channel 111 is installed at the first vertices 1171, and a second connecting pipe 17 communicating with the second flow channel 112 is installed at the second vertices 1172. The throttling device 12 includes a capillary throttling element 121 and an electronic expansion valve 122 arranged sequentially along the direction from the second interface 1322 to the second flow channel 112. The capillary throttling element 121 includes a cylindrical portion 1212 and a sleeve portion 1211 sleeved outside the cylindrical portion 1212. The sleeve portion 1211 is flat. The first surface 11a is provided and extends from the first apex 1171 to the third apex 1173. The vertical pipe section 1324 is connected to the first apex 1171, and the horizontal pipe section 1325 is perpendicular to the sleeve portion 1211 and connected to one axial end of the sleeve portion 1211. The electronic expansion valve 122 includes a valve body 1222 and a coil 1223. The valve body 1222 communicates with the second flow channel 112 at the third apex 1173. The axis of the coil 1223 is parallel to the first surface 11a and is located on the side of the valve body 1222 away from the sleeve portion 1211. The axis of the coil 1223 is inclined to the length direction of the first surface 11a, so that the electronic expansion valve 122 is located on the side away from the fourth apex 1174 of the line connecting the first apex 1171 and the second apex 1172, so that the disassembly path of the coil 1223 avoids the second pipe 17.

[0137] For example, referring to Figures 15-16, the first surface 11a can be constructed as a rectangle. The first surface 11a of the heat exchanger 11 includes four vertices, namely a first vertices 1171, a second vertices 1172, a third vertices 1173, and a fourth vertices 1174. The first vertices 1171 and 1172 are located at opposite ends of the length of the first surface 11a, and the third vertices 1173 and 1174 are located at opposite ends of the length of the first surface 11a. The first vertices 1171 and 1173 are located on the same side of the length of the first surface 11a, and the second vertices 1172 and 1174 are located on the same side of the length of the first surface 11a. A first connector 16 is provided at the first apex 1171, which is used to communicate with the first flow channel 111. A second connector 17 is provided at the second apex 1172, which is used to communicate with the second flow channel 112. Both the first connector 16 and the second connector 17 extend in a direction perpendicular to the first surface 11a.

[0138] As shown in Figure 2, the throttling device 12 includes a capillary throttling element 121 and an electronic expansion valve 122. In the direction from the second interface 1322 to the second flow channel 112, the capillary throttling element 121 and the electronic expansion valve 122 are arranged in sequence so that the refrigerant flowing to the second flow channel 112 flows through the capillary throttling element 121 and the electronic expansion valve 122 in sequence, thereby achieving dual throttling.

[0139] As shown in Figures 6 and 7, the capillary flow element 121 includes a cylindrical portion 1212 and a sleeve portion 1211. The sleeve portion 1211 is fitted over the cylindrical portion 1212 and defines a throttling channel with the cylindrical portion 1212. The sleeve portion 1211 is arranged parallel to the first surface 11a and extends from the first apex 1171 to the third apex 1173. The vertical pipe section 1324 is connected at the first apex 1171, and the horizontal pipe section 1325 extends along the length direction of the first surface 11a to be arranged perpendicular to the sleeve portion 1211. One axial end of the sleeve portion 1211 is connected to the horizontal pipe section 1325 to achieve stable communication between the capillary flow element 121 and the connecting member 132.

[0140] Meanwhile, the electronic expansion valve 122 can be configured to include a valve body 1222 and a coil 1223. The valve body 1222 is connected to the third apex 1173 and communicates with the second flow channel 112. The coil 1223 is connected to the side of the valve body 1222 facing the second apex 1172. The axis of the coil 1223 is set to be inclined to the length direction of the first surface 11a, that is, the axis of the coil 1223 is set to be inclined away from the fourth apex 1174 along the length direction of the first surface 11a, so that the electronic expansion valve 122 is located on the side away from the fourth apex 1174 of the line connecting the first apex 1171 and the second apex 1172. The area swept by the coil 1223 moving axially away from the valve body 1222 can avoid the second pipe 17, so that the disassembly path of the coil 1223 can avoid the second pipe 17.

[0141] The above settings can prevent the coil 1223 from interfering with the second connector 17 during disassembly and assembly, making the disassembly and assembly of the coil 1223 more convenient and facilitating the subsequent maintenance of the electronic expansion valve 122.

[0142] In some embodiments of this application, as shown in FIG16, the angle between the axis of the coil 1223 and the length direction of the first surface 11a can be set as the first included angle α1, and the angle between the line connecting the first apex angle 1171 and the second apex angle 1172 and the length direction of the first surface 11a can be set as the second included angle α2, wherein the first included angle α1 is greater than the second included angle α2. This ensures that the area swept by the axial movement of the coil 1223 will not interfere with the second connecting pipe 17.

[0143] In some embodiments of this application, the first included angle α1 can be set to 10°-50°. For example, the first included angle can be 20°; or 25°; or 30°; or 40°, and this application does not limit this. This ensures the ease of disassembly of the coil 122 and avoids excessively large outward extensions of the coil 122 that would result in an overly large heat exchange component 1, thus improving the design rationality of the heat exchange component 1.

[0144] In some embodiments of this application, referring to Figures 1, 4, and 7-9, one surface of the heat exchanger 11 along its thickness direction is a 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 connected to both ends of the first flow channel 111, and the third port 115 and the fourth port 116 are respectively connected to both ends of the second flow channel 112. The first interface 1321 is used to connect with the first port 113, so that the connecting member 132 and the first flow channel 111 are connected. The second interface 1322 can be connected to the third port 115 through the throttling device 12, and the third interface 1323 is connected to the filter 131.

[0145] With the above configuration, the ports of the heat exchanger 11 can be concentrated on the first surface 11a, which helps to improve the integration of the heat exchange component 1 and improves the design rationality of the heat exchange component 1.

[0146] This application also proposes a heating and cooling regulation device 1000.

[0147] As shown in Figure 17, the heating and cooling regulating device 1000 according to an embodiment of this application includes a refrigerant circulation system 100, which includes a heat exchange component 1 according to any of the above embodiments. It should be noted that the heating and cooling regulating device 1000 can be an air conditioner, a water heater, or other devices equipped with a refrigerant circulation system 100, and this application does not limit it in this regard.

[0148] According to the embodiments of this application, the heating and cooling regulating device 1000 can achieve integrated design by directly installing external components on the heat exchanger 11 without the need for additional refrigerant pipes. This reduces the space occupied by the heat exchange component 1, lowers the processing difficulty of the heat exchange component 1, reduces the probability of refrigerant leakage, improves the reliability of the heat exchange component 1, and helps to improve the overall performance of the heating and cooling regulating device 1000.

[0149] In some embodiments of this application, referring to Figures 18-19, the refrigerant circulation system 100 includes: an indoor heat exchanger 2, an outdoor heat exchanger 3, a compressor 4, a reversing valve 5, a throttling device 6, and a heat exchange component 1. The reversing valve 5 includes a D-port, an E-port, an S-port, and a C-port. The exhaust port of the compressor 4 is connected to the D-port, the intake port of the compressor 4 is connected to the S-port, the E-port is connected to one end of the indoor heat exchanger 2, the other end of the indoor heat exchanger 2 is connected to a second port 114, the C-port is connected to one end of the outdoor heat exchanger 3, the other end of the outdoor heat exchanger 3 is connected to a filter 131 through the throttling device 6, and the fourth port 116 is connected to the intake port of the compressor 4. The reversing valve 5 switches one of the E-port and C-port to be connected to the D-port and the other to be connected to the S-port.

[0150] Specifically, as shown in Figure 18, when the heating and cooling regulating device 1000 switches to the cooling mode, valve ports C and D are connected, and valve ports E and S are connected. The discharge port of 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 releasing heat flows through the throttling device 6 into the connecting device 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 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 cooling. After absorbing heat, the refrigerant 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 flow element 121, the electronic expansion valve 122, and the third port 115 to flow into the second flow channel 112. It expands and absorbs heat in the second flow channel 112 to cool down the refrigerant in the first flow channel 111 and improve the cooling effect of the refrigerant in the indoor heat exchanger 2. The refrigerant in the second flow channel 112 can flow to the suction port of the compressor 4 through the reversing valve 5 after absorbing heat.

[0151] As shown in Figure 19, when the heating and cooling regulating device 1000 switches to heating mode, valve ports C and S are connected, and valve ports E and D are connected. 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 releasing heat 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 element 6. The refrigerant flowing into the outdoor heat exchanger 3 expands and absorbs heat. After absorbing heat, the refrigerant 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. It expands and absorbs heat in the second flow channel 112 to cool down 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 in the second flow channel 112 can flow to the suction port of the compressor 4 through the reversing valve 5 after absorbing heat.

[0152] Understandably, the refrigerant circulation system 100 has a high degree of integration, occupies little space, is easy to arrange, has few components, is easy to assemble, and is highly practical, thus improving the practicality of the cooling and heating regulation device 1000.

[0153] In some embodiments of this application, the heating and cooling regulating device 1000 includes a carrier member 400 for supporting the heat exchange component 1; an external assembly is installed on one vertical side of the heat exchanger 11, and a first mounting assembly 200 is provided on the other vertical side of the heat exchanger 11 opposite to the external assembly. The first mounting assembly 200 includes a first mounting member and a first vibration damping member 202. The first mounting member connects the heat exchanger 11 and the carrier member 400, and the first vibration damping member 202 cooperates with the first mounting member and is sandwiched between the heat exchanger 11 and the carrier member 400; a second mounting assembly 300 is provided at the bottom of the heat exchanger 11. The second mounting assembly 300 includes a second mounting member and a second vibration damping member. The second mounting member is supported at the bottom of the heat exchanger 11 and connected to the carrier member 400, and the second vibration damping member is disposed between the second mounting member and the heat exchanger 11.

[0154] For example, referring to Figures 20-21, the heating and cooling regulating device 1000 includes a carrier 400, which is plate-shaped and extends vertically. The carrier 400 is used to support the heat exchange component 1 so as to realize the installation of the heat exchange component 1.

[0155] The external mounting component is installed on one vertical side of the heat exchanger 11, and a first mounting component 200 is provided on the other vertical side of the heat exchanger 11 opposite to the external mounting component. Specifically, the external mounting component can be installed on the first surface 11a of the heat exchanger 11, and the first mounting component 200 can be installed on the second surface 11b of the heat exchanger 11.

[0156] The first mounting assembly 200 includes a first mounting member and a first vibration damper. The first mounting member is connected to the second surface 11b of the plate heat exchanger. The first mounting member can be integrally formed with the plate heat exchanger or welded to the plate heat exchanger. The first mounting member is used to connect to the carrier member 400 to fix the second surface 11b of the plate heat exchanger onto the carrier member 400. The first vibration damper 202 cooperates with the first mounting member for positioning. The first vibration damper 202 is sandwiched between the second surface 11b and the carrier member 400, and is used to buffer vibrations between the second surface 11b of the plate heat exchanger and the carrier member 400.

[0157] A second mounting assembly 300 is provided at the bottom of the heat exchanger 11. The second mounting assembly 300 includes a second mounting member and a second vibration damping member. The second mounting member is supported on the bottom plate of the plate heat exchanger and is connected to the carrier member 400 so that the carrier member 400 can support the bottom of the plate heat exchanger through the second mounting member. The second vibration damping member is provided on the second mounting member and is used to support the bottom plate of the plate heat exchanger to buffer the vibration between the bottom plate of the plate heat exchanger and the carrier member 400. It should be noted that the first vibration damping member 202 and the second vibration damping member can be made of elastic materials such as rubber and foam.

[0158] With the above configuration, the first mounting component and the second mounting component can respectively limit and support the heat exchange component 1 from the horizontal and vertical directions, and the first vibration damping component 202 and the second vibration damping component can buffer the vibration of the plate heat exchanger in the horizontal and vertical directions, thereby improving the installation stability of the heat exchange component 1.

[0159] In some embodiments of this application, the first mounting member is a threaded post 201, the carrier member 400 has a through hole, the threaded post 201 passes through the through hole and is locked with a nut located on the side of the carrier member 400 away from the plate heat exchanger 11, and the first vibration damping member 202 is sleeved on the threaded post 201.

[0160] For example, referring to Figures 21-22, the first mounting component can be constructed as a threaded post 201. The threaded post 201 is welded to the second surface 11b of the plate heat exchanger 11. A through hole is provided on the carrier component 400, extending through the carrier component 400 along its thickness direction. The threaded post 201 is matched with the through hole. When the second surface 11b of the plate heat exchanger 11 is attached to the thickness side of the carrier component 400, the threaded post 201 can penetrate through the through hole and extend to the side of the carrier component 400 away from the plate heat exchanger 11. The end of the threaded post 201 is locked with a nut located on the side of the carrier component 400 away from the plate heat exchanger 11. The nut and the carrier component 400 are mutually restrictive to fix the plate heat exchanger 11 to the carrier component 400.

[0161] Meanwhile, the first damping member 202 can be constructed as a cylinder, and the first damping member 202 is sleeved on the threaded post 201 to limit the engagement with the threaded post 201, so that the first damping member 202 can be stably installed between the plate heat exchanger 11 and the carrier member 400.

[0162] The above settings can reduce the difficulty of disassembling and assembling the plate heat exchanger 11, facilitate subsequent maintenance, improve the installation stability of the plate heat exchanger 11, and enhance the overall reliability of the cooling and heating regulation device 1000.

[0163] In some embodiments of this application, the first damping member 202 includes a first part 2021 and a second part 2022. A groove 2023 is formed between the first part 2021 and the second part 2022. The first damping member 202 is also passed through the through hole. The groove 2023 is engaged with the carrier member 400. The first part 2021 and the second part 2022 are respectively located on both sides of the carrier member 400. The first part 2021 is sandwiched between the second surface 11b and the carrier member 400, and the second part 2022 is sandwiched between the nut and the carrier member 400.

[0164] For example, as shown in FIG22, the first damping member 202 includes a first part 2021 and a second part 2022, which are connected axially. A groove 2023 is formed between the first part 2021 and the second part 2022. The first damping member 202 is sleeved on the threaded post 201 and also passes through the through hole. The groove width of the groove 2023 matches the thickness of the carrier member 400, so that the part of the carrier member 400 surrounding the through hole can be engaged in the groove 2023, so that the first damping member 202 and the carrier member 400 can be engaged and connected, thereby improving the installation stability of the first damping member 202.

[0165] Simultaneously, when the first vibration damping member 202 is snapped onto the carrier member 400, the first part 2021 and the second part 2022 can be located on both sides of the carrier member 400 along the thickness direction, respectively. The first part 2021 is sandwiched between the second surface 11b of the plate heat exchanger 11 and the carrier member 400, and the second part 2022 is sandwiched between the nut and the carrier member 400. That is to say, the first part 2021 can dampen the plate heat exchanger 11 to reduce the direct impact on the plate heat exchanger 11, and the second part 2022 can dampen the nut to reduce the indirect impact on the plate heat exchanger 11. Thus, the plate heat exchanger 11 can be sufficiently damped, improving the installation stability of the plate heat exchanger 11.

[0166] In some embodiments of this application, the first part 2021 includes a plurality of sub-parts 20211 arranged sequentially along the axial direction of the threaded post 201, and the outer diameter of the first part 2021 decreases at the connection between two adjacent sub-parts 20211.

[0167] For example, referring to FIG22, the first part 2021 includes a plurality of sub-parts 20211, which are annular in shape. The plurality of sub-parts 20211 are arranged sequentially along the axial direction of the threaded post 201. The outer diameter of the first part 2021 narrows at the connection between two adjacent sub-parts 20211 to form a deformation groove 20212. Exemplarily, the first part 2021 may be configured to include two sub-parts 20211, and a deformation groove 20212 is formed between the two sub-parts 20211.

[0168] By setting the above, the deformation range of the first part 2021 can be increased to improve the vibration reduction effect of the first part 2021, thereby improving the installation stability of the heat exchange component 1.

[0169] In some embodiments of this application, the second mounting member is a base 301, the top surface 3011 of the base 301 is a plane, and the bottom surface 3012 of the base 301 is an inclined surface, so that the thickness of the base 301 gradually increases along the direction close to the carrier member 400.

[0170] For example, referring to Figures 20 and 23, the second mounting member can be constructed as a base support 301. The base support 301 is mounted on the carrier member 400 and located below the plate heat exchanger 11. The top surface 3011 of the base support 301 is constructed as a plane and is used to fit against the bottom of the plate heat exchanger 11 to support it. Simultaneously, the bottom surface 3012 of the base support 301 can be constructed as an inclined surface, with the bottom surface 3012 tilted upwards in the direction away from the carrier member 400, so that the thickness of the base support 301 gradually increases along the direction closer to the carrier member 400.

[0171] With the above configuration, the base 301 can be constructed as a triangular structure, which enhances the structural strength of the base 301, improves the support effect of the base 301, and reduces the overall weight of the base 301, thus achieving a lightweight design.

[0172] In some embodiments of this application, the end of the base 301 facing the carrier 400 is connected to the carrier 400 via a threaded connector. Specifically, a threaded hole may be provided at the end of the base 301 facing the carrier 400, and a corresponding through hole may be provided on the carrier 400. The threaded connector can pass through the through hole and connect to the threaded hole to detachably fix the base 301 to the carrier 400. This makes the base 301 easy to assemble and disassemble, facilitates subsequent maintenance, improves the installation stability of the base 301, and ensures the supporting effect of the base 301.

[0173] In some embodiments of this application, as shown in Figures 20 and 23, the second mounting member can be configured as a base support 301, the top surface 3011 of which is used to fit and support the bottom of the plate heat exchanger 11, and the second vibration damping member is configured as a vibration damping pad 302 covering the top surface 3011 of the base support 301. This simplifies the structure of the second mounting assembly 300 and ensures the vibration damping effect of the second mounting assembly 300.

[0174] In some embodiments of this application, the vibration damping pad 302 is bonded to the top surface 3011 of the base 301. Exemplarily, an adhesive can be provided between the vibration damping pad 302 and the base 301; alternatively, the vibration damping pad 302 can be made of rubber, and hot melt adhesive can be used to bond it to the base 301. These arrangements ensure the installation stability of the vibration damping pad 302 and guarantee its supporting effect.

[0175] In some embodiments of this application, as shown in FIG21, there are multiple first mounting components 200 disposed at intervals on the second surface 11b. Exemplarily, multiple first mounting components 200 may be disposed vertically spaced apart; alternatively, multiple first mounting components 200 may be arranged in an array, and this application does not limit this. This allows for better vibration damping of the plate heat exchanger 11, improving the reliability of the heating and cooling regulation device 1000.

[0176] In some embodiments of this application, as shown in FIG20, multiple second mounting components 300 can be provided, and the multiple second mounting components 300 are spaced apart in the horizontal direction to provide spaced support at the bottom of the plate heat exchanger 11. This improves the vertical installation stability of the plate heat exchanger 11 and enhances the reliability of the heating and cooling regulating device 1000.
