Using the electromagnetic distribution valve provided by the embodiment of the present disclosure, the first chamber 101 corresponds to a part of the branch opening 104, and the second chamber 102 corresponds to another part of the branch opening 104, or one of the first chamber 101 and the second chamber 102 Corresponds to all the branch openings 104, and the other of the two does not correspond to the branch opening 104. Moreover, each branch port 104 is connected to a heat exchange path. When the electromagnetic part drives the partition part to move in the valve body 100 and changes the branch openings 104 corresponding to the first chamber 101 and the second chamber 102, the refrigerant flow path composed of multiple heat exchange passages changes. Applying the electromagnetic distribution valve to the heat exchanger 400 can achieve variable shunting of the heat exchanger 400 without the need to set up multiple bypass pipe sections and one-way valves, which greatly simplifies the pipeline structure and manufacturing of the heat exchanger 400 cost.

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

In this embodiment, as shown in FIG. 5 , the two electromagnetic distribution valves are respectively referred to as the first distribution valve 106 and the second distribution valve 107 . The first distribution valve 106 and the second distribution valve 107 are arranged vertically, 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 solenoid distribution valve is located above the second chamber 102 . Here, the first distribution valve 106 and the second distribution valve 107 have corresponding branching ports 104, which means that the first distribution valve 106 has the first branching port 104 from top to bottom and the second distribution valve 107 has the first branching port 104 from top to bottom. One branch port 104 corresponds to the second branch port 104 from top to bottom of the first distribution valve 106 and the second branch port 104 from top to bottom of the second distribution valve 107, and so on.

For example, the first distribution valve 106 and the second distribution valve 107 are respectively provided with three branch openings 104, which are respectively called the first branch opening, the second branch opening and the third branch opening 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 connected to both ends of the first heat exchange passage 410 respectively.

For example, under a splitting requirement, as shown in Figure 6, the electromagnetic part of the first distribution valve 106 is controlled to drive the partition to move, so that the partition is located between the first splitting port and the second splitting port, that is, the first chamber 101 Corresponding to the first shunt port, the second compartment 102 corresponds to the second shunt port and the third shunt port; the electromagnetic part of the second distribution valve 107 is controlled to drive the partition to move, so that the partition is located between the second shunt port and the third shunt port. room, that is, the first chamber 101 corresponds to the first branch opening and the second branch opening, and the second chamber 102 corresponds to the third branch opening. 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-connected refrigerant flow path. For another example, under a splitting requirement, as shown in Figure 8, the electromagnetic part of the first distribution valve 106 is controlled to drive the partition to move, so that the partition is located below the third splitting port, that is, the first chamber 101 corresponds to all the splitting ports 104. ; Control the electromagnetic part of the second distribution valve 107 to drive the partition to move, so that the partition is located above the first branch opening, that is, the second chamber 102 corresponds to all the branch openings 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.

Optionally, when the electromagnetic part is used to drive the partition part to move between adjacent branch openings 104, the temperature of the first chamber 101 of the valve body 100 can be adjusted without changing the refrigerant flow path composed of multiple heat exchange passages.

In this embodiment, the partition does not move across the branch opening 104, so the branch openings 104 corresponding to the first compartment 101 and the second compartment 102 do not change. Therefore, the refrigerant circulation path composed of multiple heat exchange passages does not change. Change. At the same time, the partition moves between adjacent branch openings 104, so the volumes of the first compartment 101 and the second compartment 102 change, so the liquid storage volume of the first compartment 101 changes. Here, the valve body 100 of the electromagnetic distribution valve is arranged vertically, and the first chamber 101 can play a certain liquid storage role.

Optionally, as shown in FIGS. 1 and 2 , the partition part includes a partition 200 , and the electromagnetic part includes a first electromagnetic device 300 and a second electromagnetic device 302 .

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 . Moreover, a sealing ring is set on the side of the partition plate 200, and the sealing performance between the first compartment 101 and the second compartment 102 is improved through the sealing ring. The first electromagnetic device 300 is arranged at the upper end of the vertical electromagnetic distribution valve, and the second electromagnetic device 302 is arranged at the lower end of the vertical electromagnetic distribution 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, thereby pulling the partition 200 to move toward the upper end of the valve body 100; when the second electromagnetic device 302 is powered on When the first electromagnetic device 300 is powered off, the second electromagnetic coil 303 contracts under the action of electromagnetic force, thereby pulling the partition plate 200 to move toward the lower end of the valve body 100 . Furthermore, by controlling the current size of the first electromagnetic device 300 or the second electromagnetic device 302 in the energized state, the contraction degree of the first electromagnetic coil 301 or the second electromagnetic coil 303 can be adjusted, thereby adjusting the moving position of the partition 200.

However, The liquid storage amount of the first chamber 101 changes, thereby adjusting the refrigerant circulation amount of the system without changing the refrigerant circulation path. And through the plurality of flexible protrusions 105 between adjacent branch openings 104, the partition 200 can be positioned between adjacent branch openings 104.

For example, the flexible protrusion 105 can be a positioning bead. The body of the positioning bead is embedded in the inner wall of the valve body 100 , and its spring ball extends toward the inside of the valve body 100 . When the partition plate 200 moves within 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 separator 200 is positively related to the magnitude of the energizing current of the first electromagnetic device 300 or the second electromagnetic device 302 .

The first electromagnetic coil 301 and the second electromagnetic coil 303 do not interfere with the inner wall of the slide rail 210. At the same time, the inside of the slide rail 210 can play a limiting role to avoid large accidents when the first electromagnetic coil 301 and the second electromagnetic coil 303 shrink. radial movement.

For example, when the heat exchanger 400 serves 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 200 is located between the second branch opening and the third branch opening. between. Moreover, three flexible protrusions 105 are provided from top to bottom between the second branch port and the third branch port of the second distribution valve 107, as shown in Figure 7.

Obtain the frequency F of the compressor. When the frequency of the compressor F>F2 (50Hz≤F2≤70Hz), the current of the second electromagnetic device 302 controlling the second distribution valve 107 is a. At this time, the second electromagnetic coil 303 is energized and contracts. Pull the partition 200 to the uppermost flexible protrusion 105. At this time, the refrigerant circulation amount is maximum, ensuring the cooling capacity of the air conditioner under high load.

When F1<F≤F2 (30Hz≤F1≤50Hz), the current of the second electromagnetic device 302 controlling the second distribution valve 107 increases to 2a. At this time, the second electromagnetic coil 303 is energized and contracts to pull the partition 200 to the middle. At the flexible protrusion 105, the space between the uppermost and middle flexible protrusions 105 of the first chamber 101 serves to store liquid, and the refrigerant circulation amount of the system is reduced.

When F≤F1, the current of the second electromagnetic device 302 controlling the second distribution valve 107 increases to 3a. At this time, the second electromagnetic coil 303 is energized and contracts to pull the partition 200 to the lowermost flexible protrusion 105. The first The space between the uppermost and lowermost flexible protrusions 105 of the compartment 101 serves to store liquid. At this time, the liquid storage amount of the first compartment 101 is the largest and the refrigerant circulation amount of the system is the smallest. This effectively reduces the operating power of the air conditioner and improves energy efficiency without affecting the cooling capacity of the air conditioner.
