Description

Technical Field

[0001] The invention relates to the technical field of high-efficiency heat exchangers, and in particular to a high-efficiency heat exchanger for a water source heat pump unit. Background Art

[0002] Water source heat pump is a technology that utilizes low-grade thermal energy resources formed by solar energy and geothermal energy absorbed in shallow water sources on the earth's surface, such as groundwater, rivers and lakes. It adopts the principle of heat pump and realizes the transfer of low-grade thermal energy to high-grade thermal energy through the input of a small amount of high-grade electric energy.

[0003] In the prior art, water source heat pumps must be used in conjunction with heat exchangers. When in use, the heat exchanger can better absorb the heat energy in the water source (groundwater) for the evaporator part, and transfer the heat energy extracted from the groundwater to the medium that needs to be replaced for the condenser part.

[0004] However, such heat exchangers in the prior art have the following problems when used:

[0005] 1. The heat exchanger can only exchange heat with one medium. It cannot solve the following problems. When it is necessary to blow hot air indoors for heating, it is generally necessary to use air as the medium for heat exchange to extract heat from the condenser. If hot water is needed for bathing, washing dishes, and floor heating, water is needed as the exchange medium to extract heat from the condenser. If you simply pass different media into the heat exchanger and then ventilate it, it will inevitably bring a lot of moisture, which will have a poor effect. In addition, it is necessary to ensure that the moisture inside the heat exchanger is drained. This operation is more troublesome.

[0006] 2. The heat exchanger pipe length of this type of heat exchanger in the prior art is fixed, so the optimal heat exchange efficiency may not be achieved due to the limitation of the pipe length.

[0007] Therefore, a high-efficiency heat exchanger for a water source heat pump unit is needed to solve the above problems. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention can be used to cope with different heat exchange sources. When the device is used as a condenser heat exchanger of a water source heat pump unit, water can be introduced into the heat exchange fluid inlet pipe at the lower end of the first insulation tube as a heat exchange source; and air can be introduced into the heat exchange fluid inlet pipe at the lower end of the second insulation tube as a heat exchange source, and then the refrigerant that has completed heat absorption is introduced from the refrigerant inlet port, and the refrigerant enters the diversion bin, and the diversion bin can respectively enter the first heat exchange tube and the second heat exchange tube, and condense and release heat in the first heat exchange tube and the second heat exchange tube. At this time, the heat can be exchanged with the water in the first insulation tube and the air in the second insulation tube, so that hot water is generated for bathing, and hot air is generated for heating the air, and the air and water will not pollute each other.

[0020] 2. When only hot water is needed, the present invention can drive the screw to rotate by the motor, so that the movable plate and the sealing plate can be driven by the screw to move toward the second heat exchange tube, so that the sealing plate is completely covered on the outer surface of the second heat exchange tube and contacts with the first sealing ring, so that one end of the second heat exchange tube is blocked and the refrigerant cannot pass through, so that all the refrigerant will only flow through the first heat exchange tube, so that all the heat is exchanged with the water heat exchange source, thereby improving the hot water effect; similarly, only the first sealing plate needs to be covered on the outer surface of the first heat exchange tube, so that all the heat of the refrigerant can be provided to the wind heat exchange source, so as to improve the effect of blowing out hot air; at the same time, according to the different left and right movement degrees of the sealing plate, a part of the first heat exchange tube or the second heat exchange tube can be sealed, so that the refrigerant can pass through different heat exchange tubes in proportion, so that the water heat exchange source and the wind heat exchange source obtain different refrigerant heat.

[0021] 3. When the present invention is used, the refrigerant can expand the flow process as needed, and a longer path can be used for heat exchange to improve the heat exchange efficiency; by extending the right electric push rod, the semicircular sealing cover on one side of the first heat exchange tube can be tightly fitted on the lower half of the first heat exchange tube, so that the sealing cover is in contact with the second sealing ring. At this time, all the pipes in the lower half of the first heat exchange tube and the second heat exchange tube will no longer be connected to the inside of the diversion bin, but will be connected to the inside of the merging bin and the sealing cover; then the first control valve is closed and the second control valve is opened, and then When the refrigerant flows, it will flow in from the refrigerant inlet, then flow from the upper part of the first heat exchange tube and the second heat exchange tube to the merging bin, and then after merging in the merging bin, it will flow from the lower part of the first heat exchange tube and the second heat exchange tube through the first heat exchange tube, and finally enter the sealing cover, and then be discharged from the second refrigerant discharge port; in this way, the hot refrigerant will pass through the first heat exchange tube and the second heat exchange tube twice, so that the refrigerant can expand the process as needed, and can use a longer path for heat exchange to improve the heat exchange efficiency.

[0034] The distribution mechanism 6 includes a screw 601, a slide bar 602, a movable plate 603, a sealing plate 604, a first sealing ring 605, a first refrigerant discharge port 606, and a first control valve 607. The screw 601 is movably provided at the middle of the inner side of the merging chamber 4 through a bearing. The slide bar 602 is fixedly provided at the upper and lower ends of the screw 601 inside the merging chamber 4. The outer surface of the slide bar 602 is movably sleeved with a movable plate 603. The middle of the outer surface of the movable plate 603 is movably sleeved on the outer surface of the screw 601 through a thread. The movable plate 603 has a sealing plate 604 on one side thereof, and a first sealing ring 605 is fixedly provided on the outside of the first heat exchange tube 303 and the second heat exchange tube 304 inside the merging chamber 4; a first refrigerant outlet 606 is fixedly provided in the middle of the lower end of the merging chamber 4, and a first control valve 607 is fixedly provided on the outer surface of the first refrigerant outlet 606; through the distribution mechanism 6, it is possible to control whether the first heat exchange tube 303 and the second heat exchange tube 304 in the first insulation tube 1 and the second insulation tube 2 participate in the heat exchange work;

[0035] The principle is as follows: when the device is used as a condenser heat exchanger of a water source heat pump unit, water can be introduced into the heat exchange fluid inlet pipe 301 at the lower end of the first insulation tube 1 as a heat exchange source; and air can be introduced into the heat exchange fluid inlet pipe 301 at the lower end of the second insulation tube 2 as a heat exchange source, and then the refrigerant that has completed heat absorption is introduced from the refrigerant inlet port 706, and the refrigerant enters the diversion chamber 5, and is distributed by the diversion chamber 5 to enter the first heat exchange tube 303 and the second heat exchange tube 304 respectively, and in the first The heat in the first heat exchange tube 303 and the second heat exchange tube 304 is condensed and released, and the heat can be exchanged with the water in the first insulation tube 1 and the air in the second insulation tube 2, so that hot water is generated for bathing and hot air is generated for heating the air. However, the heat in the refrigerant is fixed at this time, and after the heat is distributed to the first heat exchange tube 303 and the second heat exchange tube 304 at the same time, the heat exchange effect of water and air will be reduced, but it can be used at the same time; if only hot water is needed at this time, the motor 608 can be used to drive the screw 601 Rotate, so that the movable plate 603 and the sealing plate 604 can be driven by the screw 601 to move toward the second heat exchange tube 304, so that the sealing plate 604 is completely covered on the outer surface of the second heat exchange tube 304 and contacts with the first sealing ring 605, so that one end of the second heat exchange tube 304 is blocked and the refrigerant cannot pass through, so that all the refrigerant will only flow through the first heat exchange tube 303, so that all the heat is exchanged with the water heat exchange source, thereby improving the hot water effect; similarly, only the first sealing plate 604 needs to be covered on the outer surface of the first heat exchange tube 303, so that all the heat of the refrigerant can be provided to the wind heat exchange source; so as to improve the effect of blowing out hot air; at the same time, according to the different movement degrees of the sealing plate 604, a part of the first heat exchange tube 303 or the second heat exchange tube 304 can be sealed, so that the refrigerant can pass through different heat exchange tubes in proportion, so that the water heat exchange source and the wind heat exchange source obtain different refrigerant heat; finally, the refrigerant that has completed the heat exchange is discharged from the first refrigerant discharge port 606;

[0036] Correspondingly, when the device is used as an evaporator heat exchanger, two sets of heat exchange are also provided, one set can be connected to groundwater, so that groundwater enters from the heat exchange fluid inlet pipe 301, and the other set can be connected to some high-temperature wastewater. In this way, when there is high-temperature wastewater, the high-temperature wastewater and the refrigerant are contacted for heat exchange. At this time, the refrigerant expands and evaporates in the first heat exchange tube 303 or the second heat exchange tube 304, and the evaporation absorbs heat, so heat can be obtained from these heat exchange sources. If there is no high-temperature wastewater, heat can be drawn from the constant temperature of the groundwater. The two sets of heat exchange paths of the device are independent of each other and will not pollute the groundwater. In this way, as an evaporator heat exchanger, the present invention can still meet the heat exchange needs of various fluids.

[0037] A motor 608 is fixedly arranged on one side of the merging chamber 4, and the output shaft end of the motor 608 is connected to the screw 601 through a coupling, so that the screw 601 can be driven to rotate by the motor 608;

[0038] A telescopic rod 609 is fixedly arranged between the movable plate 603 and the sealing plate 604, and a spring 610 is sleeved on the outer surface of the telescopic rod 609. The spring 610 pushes the telescopic rod 609 to extend so that the sealing plate 604 can be closely attached to the inner side wall of the merging chamber 4, thereby improving the sealing performance of the sealing plate 604 in sealing the first heat exchange tube 303 and the second heat exchange tube 304;

[0039] The regulating mechanism 7 includes an electric push rod 701, a sealing cover 702, a connecting hose 703, a second refrigerant discharge port 704, a second control valve 705, and a refrigerant inlet 706. The electric push rods 701 are fixedly arranged on both sides of the inside of the diverter bin 5, and the movable end of the electric push rod 701 is fixedly arranged with a sealing cover 702, and the middle part of the surface of the sealing cover 702 is fixedly arranged with a connecting hose 703. The second refrigerant discharge port 704 is fixedly arranged on both sides of the outer surface of the diverter bin 5. The inside of the sealing cover 702 is mutually connected with the inside of the second refrigerant discharge port 704 through the connecting hose 703, and the middle part of the lower end of the diverter bin 5 is fixedly arranged with a refrigerant inlet 706; the pipe paths of the first heat exchange tube 303 and the second heat exchange tube 304 can be adjusted by the regulating mechanism 7, so that the refrigerant can expand the process as needed, and can use a longer path for heat exchange to improve the heat exchange efficiency;

[0040] The principle is as follows; Figure 3 As shown, at this time, by extending the right electric push rod 701, the semicircular sealing cover 702 on one side of the first heat exchange tube 303 can be tightly fitted on the lower half of the first heat exchange tube 303, so that the sealing cover 702 is in contact with the second sealing ring 707. At this time, all the pipes in the lower half of the first heat exchange tube 303 and the second heat exchange tube 304 will no longer be connected to the inside of the diversion chamber 5, but will be connected to the inside of the merging chamber 4 and the sealing cover 702; then the first control valve 607 is closed and the second control valve 705 is opened, and then the refrigerant will flow from the refrigerant inlet 706, then flows from the first heat exchange tube 303 and the upper part of the second heat exchange tube 304 to the merging chamber 4, and then flows from the lower part of the first heat exchange tube 303 and the second heat exchange tube 304 through the primary heat exchange tube after merging in the merging chamber 4, and finally enters the sealing cover 702, and then is discharged from the second refrigerant discharge port 704; in this way, the hot refrigerant will pass through the first heat exchange tube 303 and the second heat exchange tube 304 twice, so that the refrigerant can expand the process as needed, and can use a longer path for heat exchange to improve the heat exchange efficiency;

[0041] And continue with Figure 3 As shown, at this time, by shortening the left electric push rod 701, the left sealing cover 702 can be driven to separate from the second heat exchange tube 304, so that the lower half of the second heat exchange tube 304 is connected to the inside of the diversion chamber 5; then the second control valve 705 is closed and the third control valve is opened, and then the refrigerant will flow in from the refrigerant inlet 706, and then pass through all the first heat exchange tubes 303 and the second heat exchange tubes 304, and enter the merging chamber 4, and then be discharged from the first refrigerant outlet 606 after merging inside the merging chamber 4;

[0042] A second sealing ring 707 is fixedly arranged on the outside of the first heat exchange tube 303 and the second heat exchange tube 304 inside the diverter bin 5. The second sealing ring 707 can ensure the sealing between the first heat exchange tube 303, the second heat exchange tube 304 and the sealing cover 702. The sealing cover 702 is a hollow semicircular cover. When the sealing cover 702 is sleeved on the lower half of the first heat exchange tube 303 or the second heat exchange tube 304, all the pipes in the lower half of the first heat exchange tube 303 and the second heat exchange tube 304 will no longer be connected to the inside of the diverter bin 5, but will be connected to the inside of the merging bin 4 and the sealing cover 702.

[0043] A second connecting flange 708 is fixedly provided at the lower end of the refrigerant inlet 706 , and the refrigerant inlet 706 can be conveniently connected to other pipelines through the second connecting flange 708 .

[0044] Working principle: When using this device, the heat exchange principle is consistent with the working principle of the water source heat pump unit heat exchanger in the prior art. The heat exchange fluid can be injected into the gap between the first insulation tube 1, the second insulation tube 2 and the first heat exchange tube 303, the second heat exchange tube 304 through the heat exchange fluid inlet pipe 301 in the heat exchange mechanism 3. Then, under the action of the baffle 305, the heat exchange fluid meanders through the first heat exchange tube 303 and the second heat exchange tube 304 and fully contacts the heat exchange tubes for heat exchange, and finally is discharged from the heat exchange fluid discharge pipe 302; while the refrigerant can enter the diversion bin 5 through the refrigerant inlet port 706, and after being diverted inside the diversion bin 5, it passes through multiple first heat exchange tubes 303 and second heat exchange tubes 304, and then merges inside the merging bin 4, and finally is discharged from the first refrigerant discharge port 606 or the second refrigerant discharge port 704;

[0045] However, when the device is used, two groups of heat exchange places are designed, which can be used to cope with different heat exchange sources. When the device is used as a condenser heat exchanger of a water source heat pump unit, water can be introduced into the heat exchange fluid inlet pipe 301 at the lower end of the first insulation tube 1 as a heat exchange source; and air can be introduced into the heat exchange fluid inlet pipe 301 at the lower end of the second insulation tube 2 as a heat exchange source, and then the refrigerant that has completed heat absorption is introduced from the refrigerant inlet port 706, and the refrigerant enters the diversion bin 5, and the diversion from the diversion bin 5 can enter the first heat exchange tube 303 and the second heat exchange tube 304 respectively, and condense and release heat in the first heat exchange tube 303 and the second heat exchange tube 304. At this time, the heat can be exchanged with the water in the first insulation tube 1 and the air in the second insulation tube 2, so that hot water is generated for bathing, and hot air is generated for heating the air, and the air and water will not pollute each other.

[0046] However, at this time, the heat in the refrigerant is certain, and it is distributed to the first heat exchange tube 303 and the second heat exchange tube 304. After the heat exchange is carried out simultaneously, the heat exchange effects of water and air will be reduced, but they can be carried out at the same time; and if there is only a demand for hot water at this time, the motor 608 can be used to drive the screw 601 to rotate, so that the movable plate 603 and the sealing plate 604 can be driven by the screw 601 to move toward the second heat exchange tube 304, so that the sealing plate 604 is completely covered on the outer surface of the second heat exchange tube 304 and contacts with the first sealing ring 605, so that one end of the second heat exchange tube 304 is blocked and the refrigerant cannot pass through, so that all the refrigerant will only pass through the first The heat exchange tube 303 flows, so that all the heat is exchanged with the water heat exchange source, thereby improving the effect of hot water; similarly, only the first sealing plate 604 is required to be covered on the outer surface of the first heat exchange tube 303, so that all the heat of the refrigerant can be provided to the wind heat exchange source; so as to improve the effect of blowing out hot air; at the same time, according to the different degrees of left and right movement of the sealing plate 604, a part of the first heat exchange tube 303 or the second heat exchange tube 304 can be sealed, so that the refrigerant can pass through different heat exchange tubes in proportion, so that the water heat exchange source and the wind heat exchange source obtain different refrigerant heat; finally, the refrigerant that has completed the heat exchange is discharged from the first refrigerant discharge port 606;

[0047] Correspondingly, when the device is used as an evaporator heat exchanger, two sets of heat exchange are also provided, one set can be connected to groundwater, so that groundwater enters from the heat exchange fluid inlet pipe 301, and the other set can be connected to some high-temperature wastewater. In this way, when there is high-temperature wastewater, the high-temperature wastewater and the refrigerant are contacted for heat exchange. At this time, the refrigerant expands and evaporates in the first heat exchange tube 303 or the second heat exchange tube 304, and the evaporation absorbs heat, so heat can be obtained from these heat exchange sources. If there is no high-temperature wastewater, heat can be drawn from the constant temperature of the groundwater. The two sets of heat exchange paths of the device are independent of each other and will not pollute the groundwater. In this way, as an evaporator heat exchanger, the present invention can still meet the heat exchange needs of various fluids.

[0048] Furthermore, when the present invention is used, the refrigerant can expand the process as needed, and can use a longer path for heat exchange to improve the heat exchange efficiency;

[0049] The principle is as follows; Figure 3 As shown, at this time, by extending the right electric push rod 701, the semicircular sealing cover 702 on one side of the first heat exchange tube 303 can be tightly fitted on the lower half of the first heat exchange tube 303, so that the sealing cover 702 is in contact with the second sealing ring 707. At this time, all the pipes in the lower half of the first heat exchange tube 303 and the second heat exchange tube 304 will no longer be connected to the inside of the diversion chamber 5, but will be connected to the inside of the merging chamber 4 and the sealing cover 702; then the first control valve 607 is closed and the second control valve 705 is opened, and then the refrigerant will flow from the refrigerant inlet 706, then flows from the first heat exchange tube 303 and the upper part of the second heat exchange tube 304 to the merging chamber 4, and then flows from the lower part of the first heat exchange tube 303 and the second heat exchange tube 304 through the primary heat exchange tube after merging in the merging chamber 4, and finally enters the sealing cover 702, and then is discharged from the second refrigerant discharge port 704; in this way, the hot refrigerant will pass through the first heat exchange tube 303 and the second heat exchange tube 304 twice, so that the refrigerant can expand the process as needed, and can use a longer path for heat exchange to improve the heat exchange efficiency;

[0050] And continue with Figure 3 As shown, by shortening the left electric push rod 701, the left sealing cover 702 can be driven to separate from the second heat exchange tube 304, so that the lower half of the second heat exchange tube 304 is connected to the inside of the diversion chamber 5; then close the second control valve 705 and open the third control valve, and then the refrigerant will flow in from the refrigerant inlet 706, and then pass through all the first heat exchange tubes 303 and the second heat exchange tubes 304, and enter the merging chamber 4, and after merging inside the merging chamber 4, it will be discharged from the first refrigerant outlet 606. At this time, the refrigerant will only flow once in the first heat exchange tube 303 and the second heat exchange tube 304.
