As shown in fig. 1-8, embodiments of the present disclosure provide an electromagnetic dispensing valve including a valve body 100 and a flow divider. Wherein, the valve body 100 is configured into a cylinder shape, one end of the valve body 100 is provided with an inlet and an outlet 103, and a plurality of branch flow ports 104 are arranged on the side surface along the axial direction of the valve body; the inlet/outlet 103 is used for allowing the refrigerant to flow into or out of the valve body 100, and the branch port 104 is used for communicating the heat exchange passage; the flow dividing port 104 is used for communicating the heat exchange passage; the shunt device comprises a partition part and an electromagnetic part; the partition is provided in the valve body 100, partitions the interior of the valve body 100 into a first chamber 101 and a second chamber 102, and is movable in the axial direction of the valve body 100; the electromagnetic part is used to drive the partition part to move in the valve body 100, so as to change the diversion port 104 corresponding to the first chamber 101 and the second chamber 102.

With the electromagnetic distribution valve provided by the embodiment of the present disclosure, the first chamber 101 corresponds to a portion of the diversion port 104, the second chamber 102 corresponds to another portion of the diversion port 104, or one of the first chamber 101 and the second chamber 102 corresponds to all of the diversion ports 104, and the other of the first chamber 101 and the second chamber 102 does not correspond to the diversion port 104. And, each of the branch ports 104 communicates with one of the heat exchange passages. After the electromagnetic part drives the partition part to move in the valve body 100 to change the flow dividing ports 104 corresponding to the first chamber 101 and the second chamber 102, the refrigerant flow path composed of the plurality of heat exchange paths is changed. The electromagnetic distribution valve is applied to the heat exchanger 400, a plurality of bypass pipe sections do not need to be arranged to be matched with the check valve, variable shunting of the heat exchanger 400 can be realized, and the pipeline structure and the manufacturing cost of the heat exchanger 400 are greatly simplified.

Optionally, two electromagnetic dispensing valves are used in combination. The two electromagnetic distribution valves are provided with corresponding branch ports 104, the two corresponding branch ports 104 are respectively connected with two ends of a heat exchange passage, and a 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 dividing requirement of the refrigerant, the refrigerant flow path formed by the plurality of heat exchange paths can be changed when the electromagnetic part drives the partition part to move across the flow dividing port 104.

In the present embodiment, as shown in fig. 5, the two electromagnetic distribution valves are simply referred to as a first distribution valve 106 and a second distribution valve 107, respectively. The first distribution valve 106 and the second distribution valve 107 are vertically arranged, and the inlet/outlet 103 of the first distribution valve 106 is located at the upper end of the valve body 100, and the inlet/outlet 103 of the second distribution valve 107 is located at the lower end of the valve body 100. Also, the first compartment 101 of each electromagnetic distribution valve is located above the second compartment 102. Here, the first distribution valve 106 and the second distribution valve 107 have corresponding branch ports 104, that is, the first branch port 104 from the top down of the first distribution valve 106 corresponds to the first branch port 104 from the top down of the second distribution valve 107, the second branch port 104 from the top down of the first distribution valve 106 corresponds to the second branch port 104 from the top down of the second distribution valve 107, and so on.

Illustratively, the first distribution valve 106 and the second distribution valve 107 are respectively provided with three branch ports 104, which are respectively referred to as a first branch port, a second branch port and a third branch port from top to bottom. The first branch port of the first distribution valve 106 and the first branch port of the second distribution valve 107 are respectively communicated with both ends of the first heat exchange passage 410, the second branch port of the first distribution valve 106 and the second branch port of the second distribution valve 107 are respectively communicated with both ends of the second heat exchange passage 420, and the third branch port of the first distribution valve 106 and the third branch port of the second distribution valve 107 are respectively communicated with both ends of the third heat exchange passage 430. For example, under a diversion demand, as shown in fig. 6, the electromagnetic part of the first distribution valve 106 is controlled to drive the partition part to move, so that the partition part is located between the first diversion port and the second diversion port, i.e. the first compartment 101 corresponds to the first diversion port, and the second compartment 102 corresponds to the second diversion port and the third diversion port; the solenoid part controlling the second distribution valve 107 moves the partition so that the partition is located between the second branch port and the third branch port, that is, the first chamber 101 corresponds to the first branch port and the second branch port, and the second chamber 102 corresponds to the third branch port. In this way, the first heat exchange path 410, the second heat exchange path 420, and the third heat exchange path 430 constitute a refrigerant circulation path in series. For another example, under a diversion demand, as shown in fig. 8, the electromagnetic part of the first distribution valve 106 is controlled to drive the partition part to move, so that the partition part is located below the third diversion port, that is, the first compartment 101 corresponds to all the diversion ports 104; the solenoid portion controlling the second distribution valve 107 moves the partition portion so that the partition portion is located above the first branch port, that is, the second partition chamber 102 corresponds to all the branch ports 104. In this way, the first heat exchange path 410, the second heat exchange path 420, and the third heat exchange path 430 constitute refrigerant circulation paths connected in parallel.

Alternatively, when the partition is moved between the adjacent branch ports 104 by the electromagnetic part, the liquid storage amount of the first compartment 101 of the valve body 100 can be adjusted without changing the refrigerant flow path formed by the plurality of heat exchange paths.

In this embodiment, the partition does not move across the flow dividing port 104, and therefore the flow dividing ports 104 corresponding to the first compartment 101 and the second compartment 102 are not changed, and thus the refrigerant flow path composed of the plurality of heat exchange paths is not changed. At the same time, the partition moves between the adjacent branch ports 104, and therefore the volumes of the first compartment 101 and the second compartment 102 change, and the amount of liquid stored in the first compartment 101 changes. Here, the valve body 100 of the electromagnetic distributing valve is vertically arranged, and the first chamber 101 can play a certain role in storing liquid.

Alternatively, as shown in fig. 1 and 2, the partition includes a partition 200, and the electromagnetic section includes a first electromagnetic device 300 and a second electromagnetic device 302. Wherein the partition plate 200 is used to partition the inner space of the valve body 100; the first electromagnetic device 300 is provided 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 disposed 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; 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, and the partition plate 200 is moved toward the corresponding end of the valve body 100.

In the present embodiment, the partition board 200 is perpendicular to the axial direction of the valve body 100, and the size of the board surface of the partition board 200 is matched with the size of the cross section of the valve body 100. And a seal ring is fitted over the side surface of the partition plate 200, and the sealing property between the first compartment 101 and the second compartment 102 is improved by the seal ring. The first solenoid device 300 is disposed at an upper end of the vertical solenoid operated dispensing valve, and the second solenoid device 302 is disposed at a lower end of the vertical solenoid operated dispensing valve. When the first electromagnetic device 300 is powered on and the second electromagnetic device 302 is powered off, the first electromagnetic coil 301 contracts under the action of electromagnetic force, so that the partition board 200 is pulled to move towards the upper end of the valve body 100; when the second solenoid 302 is energized and the first solenoid 300 is de-energized, the second solenoid 303 is contracted by the electromagnetic force, thereby pulling the diaphragm 200 to move toward the lower end of the valve body 100. By controlling the magnitude of the current of the first solenoid 300 or the second solenoid 302 in the energized state, the degree of contraction of the first solenoid coil 301 or the second solenoid coil 303 can be adjusted, and the movement position of the diaphragm 200 can be adjusted.

Optionally, a plurality of flexible protrusions 105 are disposed between adjacent diversion ports 104, and the plurality of flexible protrusions 105 are disposed along the axial direction of the valve body 100, and the flexible protrusions 105 are used for positioning the partition board 200.

In this embodiment, when the electromagnetic part drives the partition board 200 to move between the adjacent branch ports 104, the branch port 104 corresponding to the first compartment 101 and the branch port 104 of the second compartment 102 do not change, but the liquid storage amount of the first compartment 101 changes, so that the refrigerant circulation amount of the system is adjusted without changing the refrigerant circulation path. And the baffles 200 may be positioned between adjacent flow-splitting ports 104 by a plurality of flexible protrusions 105 between adjacent flow-splitting ports 104.

Illustratively, the flexible protrusions 105 may be in the form of positioning beads, the bodies of which are embedded in the inner wall of the valve body 100, and the spring beads of which extend toward the interior of the valve body 100. The diaphragm 200 is positioned when the diaphragm 200 moves within the valve body 100 and interferes with the spring ball, and the diaphragm 200 may continue to move as the force applied to the diaphragm 200 increases and presses the spring ball into the body of the positioning ball. The magnitude of the force applied to diaphragm 200 is positively correlated to the magnitude of the energizing current of first electromagnetic device 300 or second electromagnetic device 302.

Optionally, as shown in fig. 3 and 4, the divider further comprises a slide rail 210. The sliding rail 210 is configured to be annular column-shaped, and two side walls of the sliding rail 210 are thick and provided with corresponding sliding grooves 211; two opposite hollow-out areas 201 are arranged on the partition board 200, and a connection area 202 is arranged between the two hollow-out areas 201; the connection region 202 corresponds to the inside of the slide rail 210 and the slide groove 211, and the hollow region 201 corresponds to the wall thickness of the slide rail 210 without the slide groove 211.

In the present embodiment, the movement of the partition board 200 is more stabilized by the guiding action of the slide rail 210. The sliding rail 210 may be inserted through the center of the partition board 200 or through one side of the partition board 200. The number of the slide rails 210 may be one or more, for example, two slide rails 210 are respectively disposed through two sides of the partition board 200. For convenience of installation, one end of the same side of the two sliding grooves 211 is an open end. During installation, the open end of the sliding groove 211 extends to the connection area 202 of the partition board 200, and the wall thickness of the sliding rail 210, which is not provided with the sliding groove 211, extends to the hollow area 201, so that the sliding rail 210 can penetrate through the partition board 200.

Alternatively, as shown in fig. 2, the first electromagnetic coil 301 and the second electromagnetic coil 303 are both located inside the slide rail 210.

In the present embodiment, the interior of the slide rail 210 is provided as a hollow structure, providing an installation space for the first and second

electromagnetic coils

301 and 303. The first electromagnetic coil 301 is located at a portion of the slide rail 210 corresponding to the first compartment 101, and has one end connected to the first electromagnetic device 300 and the other end connected to the plate surface of the partition plate 200 located in the first compartment 101. The second electromagnetic coil 303 is located at a portion of the slide rail 210 corresponding to the second compartment 102, and has one end connected to the second electromagnetic device 302 and the other end connected to the plate surface of the partition 200 located in the second compartment 102. The initial position of the diaphragm 200 is located at an intermediate position in the axial direction of the valve body 100, and the first electromagnetic coil 301 and the second electromagnetic coil 303 are equal in length in the free state. The resistance received from the flowing refrigerant is smaller than that received in the space of the valve body 100 where the first solenoid coil 301 and the second solenoid coil 303 are disposed outside the slide rail 210. The first electromagnetic coil 301 and the second electromagnetic coil 303 have no interference with the inner wall of the slide rail 210, and meanwhile, the inside of the slide rail 210 can play a limiting role, so that large radial play is avoided when the first electromagnetic coil 301 and the second electromagnetic coil 303 shrink.

The embodiment of the present disclosure further provides a heat exchanger 400, which includes the electromagnetic distribution valve described in any of the above embodiments.

Optionally, as shown in fig. 5, a heat exchanger 400 with a variable flow dividing function includes a first main pipe 401, a second main pipe 402, a plurality of heat exchange passages, and two electromagnetic distribution valves, where the two electromagnetic distribution valves are vertically arranged, and respective flow dividing ports 104 correspond to each other from top to bottom; the first main pipeline 401 and the second main pipeline 402 are respectively connected to the inlets and outlets 103 of the two electromagnetic distribution valves, and both ends of each heat exchange channel are respectively connected to a set of branch ports 104 corresponding to the two electromagnetic distribution valves, so that variable branch is realized by adjusting the positions of the partition boards 200 corresponding to the two electromagnetic distribution valves.

In the present embodiment, the two electromagnetic distribution valves are simply referred to as a first distribution valve 106 and a second distribution valve 107, respectively. The inlet/outlet 103 of the first distribution valve 106 is located at the upper end of the valve body 100 and communicates with the first main line 401; the inlet/outlet 103 of the second distribution valve 107 is located at the lower end of the valve body 100 and communicates with the second main line 402.

Illustratively, the first distribution valve 106 and the second distribution valve 107 are respectively provided with three branch ports 104, which are respectively referred to as a first branch port, a second branch port and a third branch port from top to bottom. The first branch port of the first distribution valve 106 and the first branch port of the second distribution valve 107 communicate with both ends of the first heat exchange passage 410, the second branch port of the first distribution valve 106 and the second branch port of the second distribution valve 107 communicate with both ends of the second heat exchange passage 420, and the third branch port of the first distribution valve 106 and the third branch port of the second distribution valve 107 communicate with both ends of the third heat exchange passage 430.

As shown in fig. 6, when the heat exchanger 400 is used as a condenser, the refrigerant flows from the first main line 401 into the first compartment 101 of the first distribution valve 106. At this time, the partition 200 controlling the first distribution valve 106 is located between the first branch port and the second branch port, the partition 200 of the second distribution valve 107 is located between the second branch port and the third branch port, and the first heat exchange path 410, the second heat exchange path 420, and the third heat exchange path 430 form a refrigerant flow path in series, that is, a branch path is formed. As shown in fig. 8, when the heat exchanger 400 is used as an evaporator, the refrigerant flows from the second main line 402 into the second compartment 102 of the second distribution valve 107. At this time, the partition 200 controlling the first distribution valve 106 is located below the third branch port, the partition 200 of the second distribution valve 107 is located above the first branch port, and the first heat exchange path 410, the second heat exchange path 420, and the third heat exchange path 430 form a refrigerant circulation path in parallel, that is, three branches are formed. Thus, the heat exchanger 400 flows through fewer branches when serving as a condenser, and the refrigerant flows through more branches when the heat exchanger 400 serves as an evaporator, so that the variable flow distribution function is realized, and the performance of the heat exchanger 400 is improved. It will be appreciated that similar variable split functions can be achieved when the heat exchange paths are greater than or equal to four.

The embodiment of the present disclosure further provides an air conditioner, which includes 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 the variable flow dividing function described in any of the above embodiments.

Alternatively, the outdoor heat exchanger of the air conditioner is the heat exchanger 400 having the variable flow-dividing function described above. When the air conditioner operates in a cooling mode, the outdoor heat exchanger serves as a condenser; when the air conditioner operates in a heating mode, the outdoor heat exchanger serves as an evaporator.

Alternatively, the current of the solenoid part of the solenoid distribution valve is adjusted according to the frequency of the compressor, and the position of the partition plate 200 between the adjacent branch ports 104, that is, the liquid storage amount of the first compartment 101 of the solenoid distribution valve is adjusted, thereby adjusting the refrigerant circulation amount of the air conditioning system.
