[0054] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments may be combined with each other.

[0055] Combined with Figure 1-8 As shown, the embodiments of the present disclosure provide an electromagnetic distribution valve, which includes a valve body 100 and a flow splitting device. Among them, the valve body 100 is configured in a columnar shape, one end of the valve body 100 is provided with an inlet / outlet 103, and a plurality of flow splitting ports 104 are provided on the side surface along its axial direction; the inlet / outlet 103 is used for the refrigerant to flow into or out of the valve body 100, and the flow splitting ports 104 are used to communicate with the heat exchange passages; the flow splitting ports 104 are used to communicate with the heat exchange passages; the flow splitting device includes a partitioning part and an electromagnetic part; the partitioning part is arranged inside the valve body 100, divides the inside of the valve body 100 into a first chamber 101 and a second chamber 102, and the partitioning part can move along the axial direction of the valve body 100; the electromagnetic part is used to drive the partitioning part to move inside the valve body 100 so as to change the flow splitting ports 104 corresponding to the first chamber 101 and the second chamber 102.

[0056] By using the electromagnetic distribution valve provided by the embodiments of the present disclosure, the first chamber 101 corresponds to a part of the flow splitting ports 104, the second chamber 102 corresponds to another part of the flow splitting ports 104, or one of the first chamber 101 and the second chamber 102 corresponds to all the flow splitting ports 104 and the other does not correspond to the flow splitting ports 104. Moreover, each flow splitting port 104 communicates with a heat exchange passage. After the electromagnetic part drives the partitioning part to move inside the valve body 100 to change the flow splitting ports 104 corresponding to the first chamber 101 and the second chamber 102, the refrigerant flow path composed of multiple heat exchange passages changes. When the electromagnetic distribution valve is applied to the heat exchanger 400, it is possible to achieve variable flow splitting of the heat exchanger 400 without setting multiple bypass pipe segments and check valves in cooperation, greatly simplifying the pipeline structure and manufacturing cost of the heat exchanger 400.

[0057] Optionally, two electromagnetic distribution valves are used in cooperation. The two electromagnetic distribution valves have corresponding flow splitting ports 104, and the two corresponding flow splitting ports 104 are respectively connected to both ends of a heat exchange passage. The refrigerant flows in from the inlet / outlet 103 corresponding to one electromagnetic distribution valve and flows out from the inlet / outlet 103 corresponding to the other electromagnetic distribution valve; according to the flow splitting requirement of the refrigerant, when the electromagnetic part drives the partitioning part to move across the flow splitting port 104, the refrigerant flow path composed of multiple heat exchange passages can be changed.

[0058] In this embodiment, as Figure 5As described above, the two electromagnetic distribution valves are respectively abbreviated as the first distribution valve 106 and the second distribution valve 107. The first distribution valve 106 and the second distribution valve 107 are vertically arranged, and the inlet and outlet 103 of the first distribution valve 106 is located at the upper end of the valve body 100, and the inlet and outlet 103 of the second distribution valve 107 is located at the lower end of the valve body 100. Moreover, the first chamber 101 of each electromagnetic distribution valve is located above the second chamber 102. The fact that the first distribution valve 106 and the second distribution valve 107 have corresponding shunt ports 104 means that the first shunt port 104 from top to bottom of the first distribution valve 106 corresponds to the first shunt port 104 from top to bottom of the second distribution valve 107, the second shunt port 104 from top to bottom of the first distribution valve 106 corresponds to the second shunt port 104 from top to bottom of the second distribution valve 107, and so on.

[0059] Exemplarily, the first distribution valve 106 and the second distribution valve 107 are respectively provided with three shunt ports 104, which are respectively called the first shunt port, the second shunt port, and the third shunt port from top to bottom. The first shunt port of the first distribution valve 106 and the first shunt port of the second distribution valve 107 are respectively connected to both ends of the first heat exchange passage 410, the second shunt port of the first distribution valve 106 and the second shunt port of the second distribution valve 107 are respectively connected to both ends of the second heat exchange passage 420, and the third shunt port of the first distribution valve 106 and the third shunt port of the second distribution valve 107 are respectively connected to both ends of the third heat exchange passage 430. For example, under a certain shunt requirement, as Figure 6 shown, control the electromagnetic part of the first distribution valve 106 to drive the partition part to move so that the partition part is located between the first shunt port and the second shunt port, that is, the first chamber 101 corresponds to the first shunt port, and the second chamber 102 corresponds to the second shunt port and the third shunt port; control the electromagnetic part of the second distribution valve 107 to drive the partition part to move so that the partition part is located between the second shunt port and the third shunt port, that is, the first chamber 101 corresponds to the first shunt port and the second shunt port, and the second chamber 102 corresponds to the third shunt port. In this way, the first heat exchange passage 410, the second heat exchange passage 420, and the third heat exchange passage 430 form a series refrigerant flow path. Also for example, under a certain shunt requirement, as Figure 8 shown, control the electromagnetic part of the first distribution valve 106 to drive the partition part to move so that the partition part is located below the third shunt port, that is, the first chamber 101 corresponds to all the shunt ports 104; control the electromagnetic part of the second distribution valve 107 to drive the partition part to move so that the partition part is located above the first shunt port, that is, the second chamber 102 corresponds to all the shunt ports 104. In this way, the first heat exchange passage 410, the second heat exchange passage 420, and the third heat exchange passage 430 form a parallel refrigerant flow path.

[0060] Optionally, when the electromagnetic part drives the partition part to move between adjacent diversion openings 104, the liquid storage amount in the first chamber 101 of the valve body 100 can be adjusted without changing the refrigerant flow path formed by multiple heat exchange passages.

[0061] In this embodiment, the partition part does not move across the diversion opening 104, so the diversion openings 104 corresponding to the first chamber 101 and the second chamber 102 do not change. Therefore, the refrigerant flow path formed by multiple heat exchange passages does not change. At the same time, the partition part moves between adjacent diversion openings 104, so the volumes of the first chamber 101 and the second chamber 102 change, and thus the liquid storage amount in the first chamber 101 changes. Here, the valve body 100 of the electromagnetic distribution valve is vertically arranged, and the first chamber 101 can play a certain role in storing liquid.

[0062] Optionally, as Figure 1 and Figure 2 shown, the partition part includes a partition plate 200, and the electromagnetic part includes a first electromagnetic device 300 and a second electromagnetic device 302. Among them, the partition plate 200 is used to partition the internal space of the valve body 100; the first electromagnetic device 300 is arranged at one end of the valve body 100 corresponding to the first chamber 101 and is connected to the partition plate 200 through a first electromagnetic coil 301; the second electromagnetic device 302 is arranged at one end of the valve body 100 corresponding to the second chamber 102 and is connected to the partition plate 200 through a second electromagnetic coil 303; and when the first electromagnetic device 300 or the second electromagnetic device 302 is energized, the corresponding first electromagnetic coil 301 or second electromagnetic coil 303 contracts, thereby driving the partition plate 200 to move towards the corresponding end of the valve body 100.

[0063] In this embodiment, the partition plate 200 is arranged perpendicular to the axial direction of the valve body 100, and the size of the plate surface of the partition plate 200 is adapted to the cross-sectional size of the valve body 100. And a sealing ring is sleeved on the side surface of the partition plate 200 to improve the sealing performance between the first chamber 101 and the second chamber 102. The first electromagnetic device 300 is arranged at the upper end of the vertically arranged electromagnetic distribution valve, and the second electromagnetic device 302 is arranged at the lower end of the vertically arranged electromagnetic distribution valve. When the first electromagnetic device 300 is energized and the second electromagnetic device 302 is de-energized, the first electromagnetic coil 301 contracts under the action of electromagnetic force, thereby pulling the partition plate 200 to move towards the upper end of the valve body 100; when the second electromagnetic device 302 is energized and the first electromagnetic device 300 is de-energized, the second electromagnetic coil 303 contracts under the action of electromagnetic force, thereby pulling the partition plate 200 to move towards the lower end of the valve body 100. And by controlling the current magnitude of the energized first electromagnetic device 300 or second electromagnetic device 302, the contraction degree of the first electromagnetic coil 301 or second electromagnetic coil 303 can be adjusted, thereby adjusting the moving position of the partition plate 200.

[0064] Optionally, a plurality of flexible protrusions 105 are provided between adjacent flow split ports 104, and the plurality of flexible protrusions 105 are arranged along the axial direction of the valve body 100. The flexible protrusions 105 are used to position the partition plate 200.

[0065] In this embodiment, when the electromagnetic part drives the partition plate 200 to move between adjacent flow split ports 104, the flow split ports 104 corresponding to the first chamber 101 and the flow split ports 104 of the second chamber 102 do not change, but the liquid storage amount in the first chamber 101 changes. In this way, the refrigerant circulation amount of the system can be adjusted without changing the refrigerant flow path. And through the plurality of flexible protrusions 105 between adjacent flow split ports 104, the partition plate 200 can be positioned between adjacent flow split ports 104.

[0066] Exemplarily, the flexible protrusion 105 can adopt a positioning bead. The body of the positioning bead is embedded in the inner wall of the valve body 100, and its spring ball protrudes into the interior of the valve body 100. When the partition plate 200 moves in the valve body 100 and interferes with the spring ball, the partition plate 200 is positioned. When the force on the partition plate 200 increases and the spring ball is pressed into the body of the positioning bead, the partition plate 200 can continue to move. The magnitude of the force on the partition plate 200 is positively correlated with the magnitude of the energizing current of the first electromagnetic device 300 or the second electromagnetic device 302.

[0067] Optionally, as Figure 3 and Figure 4 shown, the partition part further includes a slide rail 210. The slide rail 210 is configured as an annular column, and corresponding sliding grooves 211 are provided on the wall thicknesses on both sides of the slide rail 210; two opposite hollow areas 201 are provided on the partition plate 200, and a connection area 202 is between the two hollow areas 201; and, the connection area 202 corresponds to the inside of the slide rail 210 and the sliding grooves 211, and the hollow areas 201 correspond to the wall thickness of the slide rail 210 where no sliding groove 211 is provided.

[0068] In this embodiment, the movement of the partition plate 200 is made more stable by the guiding action of the slide rail 210. The slide rail 210 can pass through the center of the partition plate 200 or pass through one side of the partition plate 200. The number of slide rails 210 can be one or more. For example, two slide rails 210 pass through both sides of the partition plate 200 respectively. For the convenience of installation, one end on the same side of the two sliding grooves 211 is an open end. During installation, the open end of the sliding groove 211 is extended towards the connection area 202 of the partition plate 200, and the wall thickness of the slide rail 210 where no sliding groove 211 is provided is extended towards the hollow area 201, so that the slide rail 210 can be passed through the partition plate 200.

[0069] Optionally, as Figure 2 shown, both the first electromagnetic coil 301 and the second electromagnetic coil 303 are located inside the slide rail 210.

[0070] In this embodiment, the interior of the slide rail 210 is arranged as a hollow structure, providing an installation space for the first electromagnetic coil 301 and the second electromagnetic coil 303. The first electromagnetic coil 301 is located in the part of the slide rail 210 corresponding to the first chamber 101, one end of which is connected to the first electromagnetic device 300, and the other end is connected to the plate surface of the partition 200 located in the first chamber 101. The second electromagnetic coil 303 is located in the part of the slide rail 210 corresponding to the second chamber 102, one end of which is connected to the second electromagnetic device 302, and the other end is connected to the plate surface of the partition 200 located in the second chamber 102. The initial position of the partition 200 is located at the middle position in the axial direction of the valve body 100, and the lengths of the first electromagnetic coil 301 and the second electromagnetic coil 303 in the free state are equal. Compared with arranging the first electromagnetic coil 301 and the second electromagnetic coil 303 in the space of the valve body 100 outside the slide rail 210, the resistance from the flowing refrigerant is smaller. The first electromagnetic coil 301 and the second electromagnetic coil 303 have no interference with the inner wall of the slide rail 210, and at the same time, the interior of the slide rail 210 can play a limiting role to prevent large radial displacement when the first electromagnetic coil 301 and the second electromagnetic coil 303 contract.

[0071] The embodiment of the present disclosure also provides a heat exchanger 400, including the electromagnetic distribution valve described in any of the above embodiments.

[0072] Optionally, as Figure 5 shown, a heat exchanger 400 with a variable flow splitting function includes a first main pipeline 401, a second main pipeline 402, a plurality of heat exchange passages, and two electromagnetic distribution valves. The two electromagnetic distribution valves are arranged vertically, and their respective flow splitting ports 104 correspond to each other from top to bottom; wherein, the first main pipeline 401 and the second main pipeline 402 are respectively connected to the inlet and outlet 103 of the two electromagnetic distribution valves, and both ends of each heat exchange passage are respectively connected to a group of corresponding flow splitting ports 104 of the two electromagnetic distribution valves, so as to realize variable flow splitting by adjusting the positions of the partitions 200 corresponding to the two electromagnetic distribution valves.

[0073] In this embodiment, the two electromagnetic distribution valves are respectively abbreviated as the first distribution valve 106 and the second distribution valve 107. The inlet and outlet 103 of the first distribution valve 106 are located at the upper end of the valve body 100 and communicate with the first main pipeline 401; the inlet and outlet 103 of the second distribution valve 107 are located at the lower end of the valve body 100 and communicate with the second main pipeline 402.

[0074] Exemplarily, the first distribution valve 106 and the second distribution valve 107 are each provided with three shunt ports 104, which are respectively called the first shunt port, the second shunt port, and the third shunt port from top to bottom. The first shunt port of the first distribution valve 106 and the first shunt port of the second distribution valve 107 are respectively connected to both ends of the first heat exchange path 410. The second shunt port of the first distribution valve 106 and the second shunt port of the second distribution valve 107 are respectively connected to both ends of the second heat exchange path 420. The third shunt port of the first distribution valve 106 and the third shunt port of the second distribution valve 107 are respectively connected to both ends of the third heat exchange path 430.

[0075] As Figure 6 shown, when the heat exchanger 400 is used as a condenser, the refrigerant flows from the first main pipeline 401 into the first chamber 101 of the first distribution valve 106. At this time, the partition 200 of the first distribution valve 106 is located between the first shunt port and the second shunt port, and the partition 200 of the second distribution valve 107 is located between the second shunt port and the third shunt port. The first heat exchange path 410, the second heat exchange path 420, and the third heat exchange path 430 form a series refrigerant flow path, that is, a branch is formed. As Figure 8 shown, when the heat exchanger 400 is used as an evaporator, the refrigerant flows from the second main pipeline 402 into the second chamber 102 of the second distribution valve 107. At this time, the partition 200 of the first distribution valve 106 is located below the third shunt port, and the partition 200 of the second distribution valve 107 is located above the first shunt port. The first heat exchange path 410, the second heat exchange path 420, and the third heat exchange path 430 form a parallel refrigerant flow path, that is, three branches are formed. In this way, when the heat exchanger 400 is used as a condenser, the refrigerant flows through fewer branches, and when the heat exchanger 400 is used as an evaporator, the refrigerant flows through more branches, realizing the variable shunt function and improving the performance of the heat exchanger 400. It can be understood that when the number of heat exchange paths is greater than or equal to four, a similar variable shunt function can also be achieved.

[0076] The embodiment of the present disclosure also provides an air conditioner, including the heat exchanger 400 described in any of the above embodiments. The refrigerant circulation loop of the air conditioner is at least composed of an indoor heat exchanger, an outdoor heat exchanger, a compressor, and a four-way valve, wherein the indoor heat exchanger and / or the outdoor heat exchanger is the heat exchanger 400 with a variable shunt function described in any of the above embodiments.

[0077] Optionally, the outdoor heat exchanger of the air conditioner is the heat exchanger 400 with the variable shunt function described above. When the air conditioner operates in the cooling mode, the outdoor heat exchanger serves as a condenser; when the air conditioner operates in the heating mode, the outdoor heat exchanger serves as an evaporator.

[0078] Optionally, the current magnitude of the electromagnetic part of the electromagnetic distribution valve is adjusted according to the frequency of the compressor, thereby adjusting the position of the partition plate 200 between adjacent flow split ports 104, that is, adjusting the liquid storage amount in the first chamber 101 of the electromagnetic distribution valve, so as to adjust the refrigerant circulation amount of the air-conditioning system.

[0079] In this embodiment, the position of the partition plate 200 is adjusted by adjusting the current magnitude of the first electromagnetic device 300 or the second electromagnetic device 302, and a plurality of flexible protrusions 105 are arranged between adjacent flow split ports 104, and the adjusted partition plate 200 is positioned by different flexible protrusions 105.

[0080] Exemplarily, when the heat exchanger 400 is used as a condenser, the first electromagnetic device 300 of the second distribution valve 107 is powered off and the second electromagnetic device 302 is powered on, so that the partition plate 200 is located between the second flow split port and the third flow split port. And three flexible protrusions 105 are arranged from top to bottom between the second flow split port and the third flow split port of the second distribution valve 107, as Figure 7 shown.

[0081] Obtain the frequency F of the compressor. When the frequency F of the compressor > F2 (50 Hz ≤ F2 ≤ 70 Hz), control the current of the second electromagnetic device 302 of the second distribution valve 107 to be a. At this time, the second electromagnetic coil 303 is energized and contracted to pull the partition plate 200 to the uppermost flexible protrusion 105. At this time, the refrigerant circulation amount is the largest, ensuring the refrigeration capacity under high load of the air conditioner.

[0082] When F1 < F ≤ F2 (30 Hz ≤ F1 ≤ 50 Hz), control the current of the second electromagnetic device 302 of the second distribution valve 107 to increase to 2a. At this time, the second electromagnetic coil 303 is energized and contracted to pull the partition plate 200 to the middle flexible protrusion 105. The space between the uppermost and middle flexible protrusions 105 in the first chamber 101 plays a role in storing liquid, and the refrigerant circulation amount of the system decreases.

[0083] When F ≤ F1, control the current of the second electromagnetic device 302 of the second distribution valve 107 to increase to 3a. At this time, the second electromagnetic coil 303 is energized and contracted to pull the partition plate 200 to the lowermost flexible protrusion 105. The space between the uppermost and lowermost flexible protrusions 105 in the first chamber 101 plays a role in storing liquid. At this time, the liquid storage amount in the first chamber 101 is the largest, and the refrigerant circulation amount of the system is the smallest. In this way, while not affecting the refrigeration capacity of the air conditioner, the operating power of the air conditioner is effectively reduced, and the energy efficiency is improved.

[0084] The heat exchanger includes three heat exchange passages, and the electromagnetic distribution valve is provided with three flow split ports;
