[0043] Embodiments of the present utility model will be described in detail below. 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, and should not be construed as limiting the present utility model.

[0044] 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 only examples and are not intended to limit the present utility model. In addition, the present utility model may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between various embodiments and / or settings discussed. In addition, the present utility model provides examples of various specific processes and materials, but those of ordinary skill in the art can realize the applicability of other processes and / or the use of other materials.

[0045] Next, with reference to the accompanying drawings, the heat exchange component 1 according to an embodiment of the present utility model will be described.

[0046] As Figures 1 - 11 shown, the heat exchange component 1 according to an embodiment of the present utility model includes: a heat exchanger 11 and a filter 131. At least two independent flow channels are provided in the heat exchanger 11; the filter 131 includes: a tubular shell 1311 and a filter core 1312. The filter core 1312 is installed in the tubular shell 1311, and the tubular shell 1311 is installed in the heat exchanger 11 and defines a filter channel 1313 communicating with at least one flow channel.

[0047] Thus, an integrated design can be achieved, reducing the space occupied by the heat exchange component 1, facilitating layout, reducing the processing difficulty of the heat exchange component 1, and also reducing the probability of refrigerant leakage, improving the practicability of the heat exchange component 1.

[0048] First, as Figures 1 - 4 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, a first flow channel 111 and a second flow channel 112, or more flow channels. A heat exchange medium flows through each flow channel respectively. 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). Exemplarily, the heat exchange medium in each flow channel can be a refrigerant, or exemplarily, the heat exchange medium in one flow channel is a refrigerant and the heat exchange medium in another flow channel is water or the like.

[0049] Among them, the heat exchange component 1 further includes a filter 131. The filter 131 includes a tubular shell 1311 and a filter element 1312. The tubular shell 1311 and the filter element 1312 are matched and arranged. The filter element 1312 is used to be installed inside the tubular shell 1311. The tubular shell 1311 is installed on the heat exchanger 11, such as being snap-connected, screwed or welded to the heat exchanger 11. At least one filter channel 1313 is defined inside the tubular shell 1311. The filter channel 1313 is communicated with the flow channel, so that the refrigerant flowing into or out of the flow channel can flow through the filter channel 1313. The filter element 1312 is located inside the filter channel 1313 and is used to filter the refrigerant flowing through the filter channel 1313 to eliminate impurities in the refrigerant.

[0050] It can be understood that by directly installing the filter 131 on the heat exchanger 11, there is no need to additionally arrange a refrigerant pipe to connect the filter 131 and the corresponding flow channel, which can achieve an integrated design, reduce the space occupied by the heat exchange component 1, reduce the processing cost, and since the number of components is reduced, the assembly process of the heat exchange component 1 can be simplified, the installation difficulty can be reduced, and the probability of refrigerant leakage can also be reduced.

[0051] According to the heat exchange component 1 of the embodiment of the present utility model, by directly installing the filter 131 on the heat exchanger 11, there is no need to additionally arrange a refrigerant pipe, which can achieve an integrated design, reduce the space occupied by the heat exchange component 1, facilitate layout, and can reduce the processing difficulty and the probability of refrigerant leakage of the heat exchange component 1, and improve the practicability of the heat exchange component 1.

[0052] In some embodiments of the present utility model, as Figure 2 shown, the tubular shell 1311 has a diameter-expanded section 13113. The diameter-expanded section 13113 refers to the section whose inner diameter is larger than that of the adjacent section, and the filter element 1312 is arranged inside the diameter-expanded section 13113. Through the above setting, the filter element 1312 can be more easily positioned and installed, the assembly difficulty of the filter 131 is reduced, and the flow resistance can be reduced, and the flow rate of the refrigerant is increased.

[0053] In some embodiments of the present utility model, as Figure 2 shown, the filter element 1312 includes a mounting portion 13121 and a filter mesh portion 13122. Filter holes are formed on the filter mesh portion 13122. The mounting portion 13121 is located at the edge of the filter mesh portion 13122. The mounting portion 13121 is used to connect with the tubular shell 1311 to fix the filter element 1312 on the tubular shell 1311. Thus, the stable installation of the filter element 1312 can be realized.

[0054] In some embodiments of the present utility model, the filter screen part 13122 is formed into a cylindrical shape with one axial end closed and the other axial end open. The area of the closed end of the filter screen part 13122 is smaller than the area of the open end of the filter screen part 13122, and the mounting part 13121 is connected to the open end.

[0055] For example, as shown in Figure 2 , the filter screen part 13122 is recessed from the edge to the middle to form a cylindrical shape. One end of the filter screen part 13122 along the axis is closed and the other end is open. The area of the closed end of the filter screen part 13122 is smaller than the area of the open end of the filter screen part 13122. The closed end and the open end can be smoothly connected through the side wall, so that the diameter of the filter screen part 13122 gradually decreases in the direction from the closed end to the open end. At the same time, the mounting part 13121 can be connected to the open end to arrange the mounting part 13121 at the edge of the filter screen part 13122.

[0056] Specifically, the closed end of the filter screen part 13122 can be constructed as an end point; or the closed end of the filter screen part 13122 can be constructed as an end face, and the present utility model does not limit this.

[0057] It can be understood that by constructing the filter screen part 13122 into a cylindrical shape, the flow-through area of the filter screen part 13122 can be increased, so that the refrigerant can flow through the filter screen part 13122 better, which is beneficial to reducing the flow resistance. And by arranging the mounting part 13121 at the open end, the overlap between the mounting part 13121 and the filter screen part 13122 can be reduced, further reducing the flow resistance, improving the flow stability of the refrigerant, and improving the practicability of the filter 131.

[0058] In some embodiments of the present utility model, the mounting part 13121 can be arranged to have an interference fit with the inner peripheral wall of the tubular shell 1311. Thereby, the installation stability of the filter element 1312 can be improved, the installation difficulty of the filter element 1312 can be reduced, and the reliability of the filter 131 can be improved.

[0059] In some embodiments of the present utility model, as shown in Figure 2 , the mounting part 13121 and the filter screen part 13122 are arranged in sequence along the axis of the tubular shell 1311. A clamping rib 13114 protrudes from the inner peripheral wall of the tubular shell 1311, and the clamping rib 13114 is clamped on the side of the mounting part 13121 close to the filter screen part 13122. In this way, when the filter screen part 13122 is impacted by the refrigerant and has a tendency to move in a direction away from the mounting part 13121, the clamping rib 13114 can limit the mounting part 13121 to prevent the filter element 1312 from moving in the expanded diameter section 13113. Thereby, the overall stability of the filter 131 can be improved.

[0060] Of course, the clamping rib 13114 can also be clamped on the side of the installation part 13121 away from the filter screen part 13122; alternatively, two clamping ribs can be provided, and the two clamping ribs 13114 are respectively clamped on both sides of the installation part 13121. The present utility model does not limit this.

[0061] In some embodiments of the present utility model, the tubular shell 1311 includes a first shell part 13111 and a second shell part 13112 connected along the axis, and the installation part 13121 is clamped between the first shell part 13111 and the second shell part 13112.

[0062] For example, with reference to Figure 3 As shown, the tubular shell 1311 includes a first shell part 13111 and a second shell part 13112. The first shell part 13111 and the second shell part 13112 are integrally formed. The first shell part 13111 and the second shell part 13112 are arranged in sequence along the axis and are adapted to be connected into a tubular shell 1311. The installation part 13121 protrudes outward along the radial direction. The installation part 13121 is clamped between the first shell part 13111 and the second shell part 13112 to be in limit fit with the tubular shell 1311 along the axis. Thus, the installation stability of the filter element 1312 can be improved.

[0063] In some embodiments of the present utility model, the first shell part 13111 has a first end 13111a, the second shell part 13112 has a second end 13112a. The first end 13111a covers the outside of the second end 13112a. The filter screen part 13122 is arranged inside the second shell part 13112, and at least part of the installation part 13121 extends outside the second end 13112a to be clamped between the first end 13111a and the second end 13112a.

[0064] For example, with reference to Figure 3 As shown, one end of the first shell part 13111 facing the second shell part 13112 can be set as the first end 13111a, and one end of the second shell part 13112 facing the first shell part 13111 can be set as the second end 13112a. The inner diameter of the first end 13111a matches the outer diameter of the second end 13112a, so that the first end 13111a of the first shell part 13111 can cover the outside of the second end 13112a of the second shell part 13112.

[0065] Among them, the filter screen part 13122 can be arranged inside the second shell part 13112, and at least part of the installation part 13121 can be set to extend outside the second end 13112a, so that the installation part 13121 can be clamped between the first end 13111a and the second end 13112a to be fixed on the tubular shell 1311. Thus, the installation stability of the filter element 1312 can be improved, and the reliability of the filter 131 is improved.

[0066] In some embodiments of the present utility model, the mounting portions 13121 can be provided in plurality, and the plurality of mounting portions 13121 are arranged at intervals along the circumferential direction of the filter net portion 13122 and are respectively matched with the tubular shell 1311. Thereby, the mounting stability of the filter element 131 can be improved.

[0067] In some embodiments of the present utility model, such as Figure 1 shown, the heat exchanger 11 is a plate heat exchanger. One side of the plate heat exchanger in the thickness direction has a first surface 11a. The filter 131 is arranged 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 axial end is connected to the heat exchanger 11. Through the above arrangement, the filter 131 can be more easily positioned and installed, which is beneficial to reducing the processing difficulty of the heat exchange component 1 and improving the practicability of the heat exchange component 1.

[0068] In some embodiments of the present utility model, the filter 131 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 welding or other means. Thereby, the mounting stability of the filter 131 can be improved, and the reliability of the heat exchange component 1 is improved.

[0069] In some embodiments of the present utility model, such as Figure 4 and Figure 5 shown, a first flow channel 111 and a second flow channel 112 independent of each other can be provided in the heat exchanger 11; the filter 131 includes a first filter 131a and a second filter 131b. The first filter 131a is installed in the heat exchanger 11 and is communicated 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 the heat exchanger 11 and is communicated 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.

[0070] Through the above arrangement, the refrigerant in the first flow channel 111 and the second flow channel 112 can be filtered specifically, which is beneficial to improving the filtering effect of the filter 131 and reducing the accumulation of impurities.

[0071] In some embodiments of the present utility model, the heat exchanger 11 is provided with an independent first flow channel 111 and a second flow channel 112; the heat exchanger 11 has a first port 113, a second port 114, a third port 115 and a fourth port 116. The first port 113 and the second port 114 are respectively communicated with both ends of the first flow channel 111, and the third port 115 and the fourth port 116 are respectively communicated with both ends of the second flow channel 112; the heat exchange component 1 further includes a connecting member 132, and the tubular shell 1311 is installed on the heat exchanger 11 through the 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 filter 131 is communicated with the third interface 1323.

[0072] For example, referring to Figures 5 - 10 As shown, the heat exchanger 11 is provided with an independent first flow channel 111 and a second flow channel 112. One surface of the heat exchanger 11 along 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.

[0073] Among them, the heat exchange component 1 further includes a connecting device 13. The connecting device 13 includes a filter 131 and a connecting member 132. The tubular shell 1311 is installed on the heat exchanger 11 through the 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. The first interface 1321, the second interface 1322 and the third interface 1323 are communicated with each other in pairs. The first interface 1321 is used to be communicated with the first port 113 so that the connecting member 132 and the first flow channel 111 are communicated. The second interface 1322 can be communicated with the third port 115 through a throttling device 12. The throttling device 12 includes a connected capillary throttling element 121 and an electronic expansion valve 122, so that the connecting member 132 can be communicated with the second flow channel 112 through the capillary throttling element 121 and the electronic expansion valve 122. The third interface 1323 is communicated with the filter 131.

[0074] 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.

[0075] Such as Figure 5 and Figure 9As shown, when the cooling and heating adjustment device 1000 is switched to the cooling mode, the compressor 4 can send the compressed refrigerant into the outdoor heat exchanger 3. The compressed refrigerant releases heat in the outdoor heat exchanger 3, and the refrigerant after heat release flows through the filter 131 and then flows into the connecting member 132. Part of the refrigerant flowing into the connecting member 132 can flow into the first flow channel 111 through the first interface 1321, and 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 this part of the refrigerant can flow back into the compressor 4. Another part of the refrigerant flowing into the connecting member 132 can flow through the second interface 1322, the capillary throttling element 121, the electronic expansion valve 122, and the third port 115 and then flow into the second flow channel 112, and expands and absorbs heat in the second flow channel 112 to reduce the temperature of the refrigerant in the first flow channel 111, improve the refrigeration effect of the refrigerant in the indoor heat exchanger 2, and the refrigerant flowing into 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 the refrigerant into a gaseous 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.

[0076] As Figure 6 and Figure 10 shown, when the cooling and heating adjustment device 1000 is switched 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 then flow into the outdoor heat exchanger 3. The refrigerant flowing into the outdoor heat exchanger 3 expands and absorbs heat, and then 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 then flow into the second flow channel 112, and expands and absorbs heat in the second flow channel 112 to reduce the temperature of the refrigerant in the first flow channel 111, which is beneficial to improving 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 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 the refrigerant into a gaseous 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] In addition, the refrigerant flowing into the second flow channel 112 can be throttled twice by the capillary flow element 121 and the electronic expansion valve 122, which can effectively reduce the temperature of the refrigerant in the first flow channel 111, improve the heat absorption efficiency of the refrigerant. By providing the filter 131, the filter 13 can be used to filter impurities in the refrigerant, which helps to reduce the accumulation of impurities and improve the reliability of the heat exchange component 1.

[0078] In addition, by mounting both the throttling device 12 and the filter 131 on the heat exchanger 11, an integrated design can be achieved, which helps to reduce the space occupied by the heat exchange component 1, and can simplify the processing difficulty of the heat exchange component 1, reduce the processing cost and labor cost, and improve the practicability of the heat exchange component 1.

[0079] The present utility model further provides a refrigerant circulation system 100.

[0080] As Figures 9 - 10 shown, the refrigerant circulation system 100 according to an embodiment of the present utility model includes: an indoor heat exchanger 2, an outdoor heat exchanger 3, a compressor 4, a reversing valve 5, a throttling member 6, and the heat exchange component 1 according to any of the above embodiments. 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 communicated with the D port, the suction port of the compressor 4 is communicated with the S port, the E port is communicated with one end of the indoor heat exchanger 2, the other end of the indoor heat exchanger 2 is communicated with the second port 114, the C port is communicated with one end of the outdoor heat exchanger 3, the other end of the outdoor heat exchanger 3 is communicated with the filter 131 through the throttling member 6, the fourth port 116 is communicated with the suction port of the compressor 4, and the reversing valve 5 switches one of the E port and the C port to be communicated with the D port, and the other to be communicated with the S port.

[0081] Specifically, as Figure 9As shown, when the cooling and heating adjustment device 1000 is switched to the cooling mode, the C valve port and the D valve port are communicated, and the E valve port and the S valve port are communicated. The exhaust port of the compressor 4 can send the compressed refrigerant into the outdoor heat exchanger 3 through the reversing valve 5. The compressed refrigerant releases heat in the outdoor heat exchanger 3, and the refrigerant after heat release flows through the throttling member 6 to flow into the connecting member 132. Part of the refrigerant flowing into the connecting member 132 can flow into the first flow channel 111 through the first interface 1321 and flow into the indoor heat exchanger 2 from the second port 114. The refrigerant flowing into the indoor heat exchanger 2 expands and absorbs heat to achieve refrigeration. The refrigerant in the indoor heat exchanger 2 can flow to the suction port of the compressor 4 through the reversing valve 5 after absorbing heat; another part of the refrigerant flowing into the connecting member 132 can flow through the second interface 1322, the capillary throttling element 121, the electronic expansion valve 122, and the third port 115 to flow into the second flow channel 112, and expand and absorb heat in the second flow channel 112 to reduce the temperature of the refrigerant in the first flow channel 111 and improve the refrigeration effect of the refrigerant in the indoor heat exchanger 2. The refrigerant flowing into the second flow channel 112 flows directly to the suction port of the compressor 4 through the fourth port 116 after absorbing heat.

[0082] As Figure 10 As shown, when the cooling and heating adjustment device 1000 is switched to the heating mode, the C valve port and the S valve port are communicated, and the E valve port and the D valve port are communicated. The compressor 4 can send the compressed refrigerant into the indoor heat exchanger 2 through the reversing valve 5. The compressed refrigerant releases heat in the indoor heat exchanger 2 to achieve heating. The refrigerant after heat release can flow into the first flow channel 111 of the heat exchanger 11 through the second port 114. Part of the refrigerant flowing into the first flow channel 111 can flow into the outdoor heat exchanger 3 through the throttling member 6. The refrigerant flowing into the outdoor heat exchanger 3 expands and absorbs heat, and the refrigerant after absorbing heat flows to the suction port of the compressor 4 through the reversing valve 5; another part of the refrigerant flowing into the first flow channel 111 can flow through the second interface 1322, the capillary throttling element 121, the electronic expansion valve 122, and the third port 115 to flow into the second flow channel 112, and expand and absorb heat in the second flow channel 112 to cool the refrigerant in the first flow channel 111, which is beneficial to improving the heat absorption efficiency of the refrigerant in the outdoor heat exchanger 3, and the refrigerant in the second flow channel 112 can flow to the suction port of the compressor 4 through the fourth port 116 after absorbing heat.
