Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, but should not be construed as limiting the present utility model.

[0043] 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.

[0044] Next, with reference to the accompanying drawings, the heat exchange component 1 according to an embodiment of the present utility model will be described.

[0045] As Figures 1 - 12 shown, the heat exchange component 1 of the embodiment of the present utility model includes: a heat exchanger 11 and a capillary throttling element 121. At least two independent flow channels are provided in the heat exchanger 11; the capillary throttling element 121 is installed on the heat exchanger 11 and includes a sleeve portion 1211 and a columnar portion 1212. The sleeve portion 1211 is sleeved outside the columnar portion 1212 to form a throttling channel between the sleeve portion 1211 and the columnar portion 1212, and the throttling channel is communicated with the second flow channel 112.

[0046] Thus, an integrated design can be achieved, reducing the space occupied by the heat exchange component 1, facilitating layout, and being conducive to reducing the installation difficulty of the heat exchange component 1, thereby improving the practicability of the heat exchange component 1.

[0047] First, as Figures 1 - 3 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, namely 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 medium). Exemplarily, the heat exchange medium in each flow channel can be a refrigerant medium, or exemplarily, the heat exchange medium in one flow channel is a refrigerant medium, and the heat exchange medium in another flow channel is water or the like.

[0048] Among them, the heat exchange component 1 further includes a capillary throttling element 121, and the capillary throttling element 121 is installed on the heat exchanger 11. For example, the capillary throttling element 121 can be welded to the heat exchanger 11. The capillary throttling element 121 includes a sleeve portion 1211 and a columnar portion 1212. The sleeve portion 1211 and the columnar portion 1212 are arranged in a matching manner. The sleeve portion 1211 is sleeved outside the columnar portion 1212, and a throttling channel is formed between the inner wall of the sleeve portion 1211 and the outer wall of the columnar portion 1212. The throttling channel is communicated with the second flow channel 112, and the throttling channel is used to introduce the refrigerant into the second flow channel 112.

[0049] Exemplarily, such as Figure 6 , Figure 7 , Figure 10 and Figure 11 shown, it can be set that the heat exchanger 11 is provided with a first flow channel 111 and a second flow channel 112. The first flow channel 111 is respectively communicated with the outdoor heat exchanger 3 and the indoor heat exchanger 2. The inlet of the second flow channel 112 is communicated with the first flow channel 111 through the throttling channel, and the outlet of the second flow channel 112 is communicated with the compressor 4.

[0050] Such as Figure 6 and Figure 10 shown, when the cooling and heating adjustment device 1000 is switched to the refrigeration 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. A part of the refrigerant flowing into the first flow channel 111 can flow along the first flow channel 111 to flow into the indoor heat exchanger 2. The refrigerant flowing into the indoor heat exchanger 2 expands and absorbs heat to achieve refrigeration, and flows back into the compressor 4 after heat absorption; another part of the refrigerant flowing into the first flow channel 111 can flow into the second flow channel 112 through the throttling channel, and expands and absorbs heat in the second flow channel 112 to reduce the temperature of the refrigerant flowing out of the first flow channel 111 and improve the refrigeration effect of the refrigerant in the indoor heat exchanger 2. The refrigerant in the second flow channel 112 flows back into the compressor 4 after heat absorption.

[0051] Such as Figure 7 and Figure 11As shown, when the cooling and heating 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, and the refrigerant after heat release 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. The refrigerant flowing into the outdoor heat exchanger 3 expands and absorbs heat, and flows back into the compressor 4 after heat absorption; another part of the refrigerant flowing into the first flow channel 111 can flow into the second flow channel 112 through the throttling channel, and expands and absorbs heat in the second flow channel 112 to reduce the temperature of the refrigerant flowing into the outdoor heat exchanger 3 and improve the heat absorption efficiency of the refrigerant in the outdoor heat exchanger 3. The refrigerant in the second flow channel 112 flows back into the compressor 4 after heat absorption.

[0052] It can be understood that by directly installing the capillary throttling element 121 on the heat exchanger 11, there is no need to additionally arrange a refrigerant pipe to connect the capillary throttling element 121 and the corresponding flow channel, realizing an integrated design, which can reduce the space occupation of 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, and the processing difficulty is reduced.

[0053] In addition, by setting that the throttling channel is jointly defined by the sleeve part 1211 and the column part 1212, the processing difficulty of the capillary throttling element 121 can be reduced, and the volume of the capillary throttling element 121 can be reduced, making it easier to integrate.

[0054] According to the heat exchange component 1 of the embodiment of the present utility model, by installing the capillary throttling element 121 on the heat exchanger 11, there is no need to additionally arrange a refrigerant pipe, realizing an integrated design, reducing the space occupation of the heat exchange component 1, facilitating layout, and being beneficial to reducing the processing difficulty of the heat exchange component 1 and improving the practicability of the heat exchange component 1.

[0055] In some embodiments of the present utility model, as Figure 3 shown, the inner peripheral wall of the sleeve part 1211 and / or the outer peripheral wall of the column part 1212 is provided with a rib 1213, and the rib 1213 participates in defining the throttling channel. Specifically, a rib 1213 can be provided on the inner peripheral wall of the sleeve part 1211; or, a rib 1213 can be provided on the outer peripheral wall of the column part 1212; or, ribs 1213 can be respectively provided on the inner peripheral wall of the sleeve part 1211 and the outer peripheral wall of the column part 1212, and the present application does not limit this. Among them, there is a fitting gap between the inner peripheral wall of the sleeve part 1211 and the outer peripheral wall of the column part 1212, and the rib 1213 can divide the fitting gap to define the throttling channel.

[0056] Through the above settings, the forming difficulty of the throttling channel can be reduced, which is beneficial to reducing the overall processing difficulty of the capillary throttling element 121 and improving the practicability of the capillary throttling element 121.

[0057] In some embodiments of the present utility model, as Figures 3 - 4 shown, the rib 1213 can be configured as a helical rib coiled around the central axis of the cylindrical portion 1212, so that the throttling channel can be formed in a spiral shape. Thereby, the space of the capillary throttling element 121 can be utilized to the maximum extent, the length of the throttling channel is extended, and the throttling effect of the capillary throttling element 121 is improved.

[0058] In some embodiments of the present utility model, as Figures 2 - 5 shown, the sleeve portion 1211 can be configured as a sleeve with an equal-diameter inner peripheral wall, and the cylindrical portion 1212 can be configured as a cylinder with an equal-diameter outer peripheral wall. Through the above settings, the uniformity of the overall throttling channel can be ensured, which is beneficial to improving the throttling effect of the capillary throttling element 121, and the processing difficulty of the capillary throttling element 121 can be reduced, and the practicability of the heat exchange component 1 is improved.

[0059] Of course, the present utility model is not limited thereto. The sleeve portion 1211 can also be configured as a sleeve with a gradually decreasing diameter, and the cylindrical portion 1212 can be configured as a cylinder with a gradually decreasing diameter. Thereby, it is convenient to realize the positioning between the sleeve portion 1211 and the cylindrical portion 1212 group, and the processing difficulty of the capillary throttling element 121 is reduced.

[0060] In some embodiments of the present utility model, the barrel wall of the sleeve portion 1211 is provided with a first through hole 12111 and a second through hole 12112 communicating with the throttling channel. The opening area of the first through hole 12111 is larger than the opening area of the second through hole 12112, and the first through hole 12111 and the second through hole 12112 are axially spaced apart along the sleeve portion 1211.

[0061] For example, referring to Figures 2 - 5 shown, the barrel wall of the sleeve portion 1211 is provided with a first through hole 12111 and a second through hole 12112. The first through hole 12111 and the second through hole 12112 are axially spaced apart along the sleeve portion 1211, so that the first through hole 12111 and the second through hole 12112 can be respectively located at both ends of the throttling channel and communicate with the throttling channel. The first through hole 12111 is used to communicate with the first flow channel 111, so that the refrigerant in the first flow channel 111 can flow into the throttling channel through the first through hole 12111. The second through hole 12112 is used to communicate with the second flow channel 112, so that the refrigerant in the throttling channel can flow into the second flow channel 112 through the second through hole 12112.

[0062] Among them, the opening area of the first through hole 12111 can be set to be larger than the opening area of the second through hole 12112, so that the flow-through area between the first flow channel 111 and the throttling channel is larger than the flow-through area between the second flow channel 112 and the throttling channel.

[0063] It can be understood that by opening the first perforation 12111 and the second perforation 12112 in the wall of the sleeve portion 1211, the processing difficulty of the first perforation 12111 and the second perforation 12112 can be reduced, and the overall processing difficulty of the capillary flow element 121 can be reduced. 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 and the throttling effect can be guaranteed to a certain extent.

[0064] In some embodiments of the present invention, Figure 5 As shown, the center line of the first through hole 12111 and the center line of the second through hole 12112 can be set to be parallel to the central axis of the sleeve portion 1211. Through the above arrangement, the first through hole 12111 and the second through hole 12112 can be located on the same side of the sleeve portion 1211, which is conducive to reducing the layout difficulty of the capillary flow element 121 and improving the practicality of the capillary flow element 121.

[0065] In some embodiments of the present invention, Figure 3 As shown, a stopper 1214 may be provided at one axial end of the column 1212, the stopper 1214 being annular in structure, and being protruded outwardly in the radial direction of the column 1212, and being used to stop outside the axial end of the sleeve 1211 to achieve positioning between the sleeve 1211 and the column 1212, and the stopper 1214 may also be used to cover the axial end of the sleeve 1211 to close the matching gap between the sleeve 1211 and the column 1212. It should be noted that the axial end of the sleeve 1211 away from the stopper 1214 may be sealed by a sealant.

[0066] Through the above arrangement, the difficulty of processing the capillary flow element 121 can be reduced, and the structural stability of the capillary flow element 121 can be improved, and the reliability of the capillary flow element 121 can be improved.

[0067] In some embodiments of the present invention, Figures 3 - 4 As shown, the stopper 1214 and the column 1212 are constructed as an integral part, and the sleeve 1211 can be fixed on the column 1212 by welding the stopper 1214 to the sleeve 1211. Through the above arrangement, the connection difficulty between the sleeve 1211 and the column 1212 can be reduced, the connection stability between the sleeve 1211 and the column 1212 can be improved, and the overall reliability of the capillary flow element 121 is ensured.

[0068] In some embodiments of the present utility model, the heat exchanger 11 is a plate heat exchanger and has a first surface 11a. The capillary throttling element 121 is disposed on the side where the first surface 11a is located. The capillary throttling element 121 is disposed at one end in the length direction of the first surface 11a, and the central axis of the sleeve portion 1211 extends along the width direction of the first surface 11a.

[0069] For example, referring to Figure 1 and Figure 6 as shown, the heat exchanger 11 can be configured as a plate heat exchanger. The first flow channel 111 and the second flow channel 112 extend along the length direction of the plate heat exchanger. One surface of the plate heat exchanger in the thickness direction is set as the first surface 11a, and the capillary throttling element 121 is disposed on the side where the first surface 11a is located. Among them, the capillary throttling element 121 can be disposed at one end in the length direction of the first surface 11a, and the capillary throttling element 121 is arranged to extend along the width direction of the first surface 11a so that the capillary throttling element 121 can be located at one side edge of the first surface 11a in the length direction.

[0070] Through the above settings, it is easier to position between the capillary throttling element 121 and the heat exchanger 11, and the processing difficulty of the heat exchange component 1 is reduced.

[0071] In some embodiments of the present utility model, the capillary throttling element 121 and the heat exchanger 11 can be integrally connected. The integral connection means non-detachable and fixed into one body. For example, it can be fixed by means such as welding. Thereby, the installation stability of the capillary throttling element 121 can be improved, and the reliability of the heat exchange component 1 is improved.

[0072] In some embodiments of the present utility model, the heat exchanger 11 is provided with independent first and second flow channels 111 and 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 connecting device 13. The connecting device 13 is installed on the heat exchanger 11 and includes a filter 131 and a connecting member 132. The connecting member 132 includes a first interface 1321, a second interface 1322 and a third interface 1323 that are communicated with each other in pairs. 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 a capillary throttling element 121 and an electronic expansion valve 122, and the third interface 1323 is communicated with the filter 131.

[0073] For example, referring to Figure 1 and Figures 6 - 11As shown, the heat exchanger 11 is provided with independent first and second flow channels 111 and 112 therein. The heat exchanger 11 is configured as a plate heat exchanger. One surface of the plate heat exchanger 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.

[0074] 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 welding the connecting device 13 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 pairwise. 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. 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.

[0075] 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.

[0076] Such as Figure 6 and Figure 10As 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 flows through the filter 131 and into the connector 132. Part of the refrigerant flowing into the connector 132 can flow into the first flow channel 111 through the first interface 1321, and then flow into the indoor heat exchanger 2 from the second port 114. The refrigerant flowing into the indoor heat exchanger 2 expands and absorbs heat to achieve cooling, and then flows back into the compressor 4. Another part of the refrigerant flowing into the connector 132 can flow through the second interface 1322, the capillary throttling element 121, the electronic expansion valve 122, and the third port 115 and into the second flow channel 112. The refrigerant expands and absorbs heat in the second flow channel 112 to reduce the temperature of the refrigerant flowing into the indoor heat exchanger 2 and improve the refrigeration effect of the refrigerant in the indoor heat exchanger 2. The refrigerant in the second flow channel 112 flows back into the compressor 4 through the fourth port 116 after absorbing heat. The power and the amount of refrigerant flowing back into the compressor 4 can be controlled by controlling the opening degree of the electronic expansion valve 122. The refrigerant is throttled to make it a gas state to prevent liquid hammer, and the refrigerant flows back into the compressor 4 for liquid supplement, so that the compressor 4 can work efficiently.

[0077] As Figure 7 and Figure 11 shown, when the cooling and heating 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, and 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 through the filter 131 and into the outdoor heat exchanger 3. The refrigerant flowing into the outdoor heat exchanger 3 expands and absorbs heat, and flows back into the compressor 4 after absorbing heat. 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 into the second flow channel 112. The refrigerant expands and absorbs heat in the second flow channel 112 to reduce the temperature of the refrigerant flowing into the outdoor heat exchanger 3 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 back into the compressor 4 through the fourth port 116 after absorbing heat. The power and the amount of refrigerant flowing back into the compressor 4 can be controlled by controlling the opening degree of the electronic expansion valve 122. The refrigerant is throttled to make it a gas state to prevent liquid hammer, and the refrigerant flows back into the compressor 4 for liquid supplement, so that the compressor 4 can work efficiently.

[0078] In addition, the capillary throttling element 121 and the electronic expansion valve 122 can double throttle the refrigerant flowing to the second flow channel 112, which can reduce the temperature of the refrigerant in the first flow channel 111 and improve the heat absorption effect of the refrigerant. The filter 131 can be used to filter impurities in the refrigerant to reduce the impurities in the refrigerant, thereby reducing the accumulation of impurities and improving the reliability of the heat exchange component 1.

[0079] In addition, by installing both the throttling device 12 and the filter 131 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 processing difficulty of the heat exchange component 1, lower the processing cost and labor cost, and improve the practicability of the heat exchange component 1.
