[0039] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application.

[0040] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0041] See also Figure 1 The present application provides a heat exchange unit 100. The heat exchange unit 100 includes a heat exchange component 10, a network supply and return pipeline 20, and a first straight pipe 21. A heat exchange medium is stored in the network supply and return pipeline 20. The first straight pipe 21 connects the network supply and return pipeline 20 and the heat exchange medium side of the heat exchange component 10.

[0042] Specifically, one end of the first straight pipe 21 can be connected to the heat exchange medium side of the heat exchange component 10 by screwing or welding, and the other end of the first straight pipe 21 can be connected to a network supply and return pipeline 20 by screwing or welding, so that the heat exchange medium flowing from the network supply and return pipeline 20 through the first straight pipe 21 and entering the heat medium side of the heat exchange component 10 is subject to an operating resistance not higher than 50 kPa. The overall transmission, heat transfer, heat exchange and energy-saving efficiency of the heat exchange unit 100 is high, the operating energy consumption is low, and the energy-saving efficiency of the heat exchange unit 100 can be improved by 10% to 20%.

[0043] When the heat exchange unit 100 is working, the heat exchange medium stored in a network supply and return pipeline 20 can flow from the network supply and return pipeline 20 through the first straight pipe 21 into the heat exchange medium side of the heat exchange component 10, and exchange heat with the water in the heat exchange component 10 to realize the vaporization of water into warm air.

[0044] It should be noted that the heat exchange medium may be water, etc. The first straight tube 21 may be made of metal. That is, the first straight tube 21 may be made of, for example, aluminum alloy, so as to reduce the overall weight of the heat exchange unit 100 while increasing the rigidity of the first straight tube 21 and extending its service life.

[0045] In this way, since the volume and internal resistance of the first straight pipe 21 are relatively small, the supply and return pipeline 20 of the heat exchanger unit 100 of the present application is connected to the heat exchange medium side of the heat exchange component 10 through the first straight pipe 21, which can reduce the space occupied by the heat exchanger unit 100, increase the flow rate of the heat exchange medium flowing into the heat exchange component 10, and will not occupy too much maintenance space of the heat exchanger unit 100. The maintenance space is relatively large, which is convenient for users to perform subsequent maintenance on the heat exchanger unit 100.

[0046] Please combine Figure 1 , Figure 2 and Figure 3 In some embodiments, the heat exchange unit 100 further includes a heat source (not shown in the figure). A network supply and return pipeline 20 includes a network supply pipeline 23 and a network return pipeline 25. One end of the network supply pipeline 23 is connected to the heat source, and the other end of the network supply pipeline 23 is connected to the inlet end of the heat medium side of the heat exchange component 10 through the first straight pipe 21. One end of a network return pipeline 25 is connected to the heat source. The other end of a network return pipeline 25 is connected to the outlet end of the heat exchange medium side of the heat exchange component 10 through the first straight pipe 21.

[0047] Specifically, one end of a network supply pipeline 23 can be connected to the heat source by screwing or welding, and the other end of a network supply pipeline 23 can be connected to the inlet end of the heat medium side of the heat exchange component 10 by screwing or welding through the first straight pipe 21, and one end of a network return pipeline 25 can be connected to the heat source by screwing or welding, and the other end of a network return pipeline 25 can be connected to the outlet end of the heat exchange medium side of the heat exchange component 10 by screwing or welding through the first straight pipe 21 to form a closed circulation pipeline, so that the heat exchange medium can flow and circulate between the network supply pipeline 23, the network return pipeline 25, the heat source and the heat exchange component 10. It should be noted that the heat source can be a solar collector or a heating device, etc.

[0048] When the heat exchange unit 100 is working, the heat source can heat the heat exchange medium. The heated heat source can enter the heat exchange medium side of the heat exchange component 10 from the inlet end of the heat exchange medium side of the heat exchange component 10 through a network supply pipeline 23 and a first straight pipe 21 connected to the network supply pipeline 23, and exchange heat with the water in the heat exchange component 10 to achieve the vaporization of water into warm air. Then, the heat exchange medium after heat exchange can flow out from the outlet end of the heat exchange medium side of the heat exchange component 10, and flow back to the heat source through the first straight pipe 21 connected to a network return pipeline 25 and a network return pipeline 25. At this time, the heat source can heat the heat exchange medium after heat exchange. This cycle is repeated, so that the heated heat exchange medium continuously flows into the heat exchange medium side of the heat exchange component 10, exchanges heat with the water in the heat exchange component 10, and then realizes the continuous circulation heat exchange between the heat exchange medium and the water.

[0049] See also Figure 2 and Figure 3 In some embodiments, a first disconnect switch 231 is provided on a network supply pipeline 23. A second disconnect switch 251 is provided on a network return pipeline 25. The first disconnect switch 231 is used to control the opening or closing of a network supply pipeline 23. The second disconnect switch 251 is used to control the opening or closing of a network return pipeline 25.

[0050] Specifically, the first shutoff switch 231 can be set on a network supply pipeline 23 by screwing or welding, so as to control the opening or closing of a network supply pipeline 23 by the first shutoff switch 231, thereby ensuring the safe operation of the heat exchange unit 100. The second shutoff switch 251 can be set on a network return pipeline 25 by screwing or welding, so as to control the opening or closing of a network return pipeline 25 by the second shutoff switch 251, thereby ensuring the safe operation of the heat exchange unit 100. It should be noted that both the first shutoff switch 231 and the second shutoff switch 251 can be shutoff ball valves.

[0051] In one embodiment, when the heat exchanger unit 100 is working, the first shut-off switch 231 and the second shut-off switch 251 can be changed from open to closed, so that a network supply pipeline 23 and a network return pipeline 25 are opened. At this time, the heat exchange medium can circulate between a network supply pipeline 23, a network return pipeline 25, the heat source and the heat exchange medium side of the heat exchange component 10, thereby realizing circulating heat exchange between the heat exchange medium and water.

[0052] In another embodiment, when it is necessary to stop the heat exchange between the heat exchange medium and water, the first shut-off switch 231 and the second shut-off switch 251 can be changed from closed to open, so that a network supply pipeline 23 and a network return pipeline 25 are closed. At this time, the heat exchange medium stops circulating between a network supply pipeline 23, a network return pipeline 25, the heat source and the heat exchange medium side of the heat exchange component 10, so that the heat exchange medium stops exchanging heat with water.

[0053] Please combine Figure 1 and Figure 2 In some embodiments, the heat exchange unit 100 further includes a sewage main pipe 30. A first horizontal expansion and decontamination device 232 and a first sewage valve 233 are also provided on the network supply pipeline 23. One end of the first sewage valve 233 is connected to the first horizontal expansion and decontamination device 232. The other end of the first sewage valve 233 is connected to the sewage main pipe 30. The first horizontal expansion and decontamination device 232 is used to filter the debris in the heat exchange medium. The first sewage valve 233 is used to discharge the debris to the sewage main pipe 30.

[0054] Specifically, the first horizontal expansion filter 232 can be set on a network supply pipeline 23 by screwing or welding, and is located between the first shut-off switch 231 and the first drain valve 233, so as to filter the debris in the heat exchange medium through the first horizontal expansion filter 232 to prevent the debris in the heat exchange medium from flowing into the heat exchange medium side of the heat exchange component 10 along with the heat exchange medium.

[0055] One end of the first sewage valve 233 can be connected to the first horizontal expansion and decontamination device 232 by screwing or welding, and the other end of the first sewage valve 233 can be connected to the sewage main pipe 30 by screwing or welding, so that after the first horizontal expansion and decontamination device 232 filters out the debris in the heat exchange medium, the first sewage valve 233 is opened to discharge the debris from the network supply pipeline 23 into the sewage main pipe 30.

[0056] It should be noted that the first drain valve 233 can be a clamp-type thin ball valve. The first horizontal expansion decontaminant 232 has a good filtering effect, and the filter screen built into the first horizontal expansion decontaminant 232 is convenient to disassemble and wash, so the maintenance cost of the first horizontal expansion decontaminant 232 is low when the present application maintains it in the later stage.

[0057] Before leaving the factory, a network supply and return pipeline 20 can be directly connected to the heat exchange component 10 through the first straight pipe 21, and then the heat exchanger unit 100 can be transported as a whole. Therefore, there is no need to assemble the heat exchanger unit 100 on site, the construction difficulty is relatively small, the efficiency is relatively high, the cost is relatively low, and the ability requirements for the construction team are relatively low, and it can be supplied in batches as a complete set.

[0058] When the heat exchange unit 100 is working, the heat exchange medium heated by the heat source flows into a return supply pipeline through the first shut-off switch 231, and then can pass through the first horizontal expansion filter 232 to filter the impurities in the heat exchange medium. At this time, the first sewage valve 233 can be opened to discharge the impurities from the network supply pipeline 23 to the sewage main pipe 30. Then, the filtered heat exchange medium can pass through the network supply pipeline 23 and the first straight pipe 21, and enter the heat exchange medium side of the heat exchange component 10 from the inlet end of the heat exchange medium side of the heat exchange component 10 to exchange heat with the water of the heat exchange component 10.

[0059] See also Figure 3 In some embodiments, a second drain valve 253 is provided on a network return pipeline 25, and the second drain valve 253 is connected to the drain main pipe 30. That is, the second drain valve 253 can be provided on the network return pipeline 25 by screwing or welding, and one end of the second drain valve 253 can be connected to the drain main pipe 30 by screwing or welding. When there are foreign matters in the heat exchange medium in the network return pipeline 25, the second drain valve 253 can be opened to discharge the foreign matters from the network return pipeline 25 to the drain main pipe 30. It should be noted that the second drain valve 253 can be a sandwiched thin ball valve.

[0060] See also Figure 2 In some embodiments, first pressure detectors 234 are provided at both ends of the first horizontal expansion and decontamination device 232. The first pressure detector 234 is used to detect the pressure change at both ends of the first horizontal expansion and decontamination device 232.

[0061] Specifically, Figure 2As shown, the number of the first pressure detectors 234 can be two, one of which can be set at one end of the first horizontal expansion and decontamination device 232, and the other first pressure detector 234 can be set at the other end of the first horizontal expansion and decontamination device 232, so as to observe the pressure value change between the heat exchange medium before filtration and the heat exchange medium after filtration through the two first pressure detectors 234, that is, if the pressure value change between the heat exchange medium before filtration and the heat exchange medium after filtration observed by the two first pressure detectors 234 is within the predetermined pressure range, it means that there is no abnormality in the first horizontal expansion and decontamination device 232; if the pressure value change between the heat exchange medium before filtration and the heat exchange medium after filtration observed by the two first pressure detectors 234 is not within the predetermined pressure range, it means that the first horizontal expansion and decontamination device 232 has an abnormality, and the user can be reminded to perform maintenance inspection on the first horizontal expansion and decontamination device 232 in time.

[0062] It should be noted that Figure 2 The two first pressure detectors 234 provided on the first horizontal expansion and decontamination device 232 are shown for illustration only. The number of the first pressure detectors 234 provided on the first horizontal expansion and decontamination device 232 may be, for example, 3, 4, 5, 6, 7 or 8, which is not limited here. The predetermined pressure range may be, for example, 0.03Mpa to 1.6Mpa. The first pressure detector 234 may be a pressure gauge and a pressure transmitter.

[0063] In some embodiments, a first bypass switch 235 and a temperature control valve 236 are further provided on the network supply pipeline 23. The bypass switch and the temperature control valve 236 are used to regulate the flow of the heat exchange medium flowing in the network supply pipeline 23. That is, when the heat exchange unit 100 is working, the flow of the heat exchange medium flowing in the network supply pipeline 23 can be regulated by controlling the opening and closing degree of the first bypass switch 235 and the temperature control valve 236. It should be noted that the first bypass switch 235 can be a bypass ball valve.

[0064] In some embodiments, a heat meter 255 is provided on a network return pipe 25. The heat meter 255 is used to analyze the heat exchange efficiency of the heat exchange medium flowing through the heat exchange medium side of the heat exchange component 10. That is, the heat meter 255 may include two heat meter probes. One heat meter probe is built into the heat meter 255 to detect the heat of the heat exchange medium flowing through a network return pipe 25, and the other is inserted into a network supply pipe 23 to detect the heat of the heat exchange medium flowing through a network supply pipe 23, so as to analyze the heat exchange efficiency of the heat exchange medium in the heat exchange component 10 with water through the heat meter 255, that is, if the heat exchange efficiency of the heat exchange medium in the heat exchange component 10 with water changes little through the heat meter 255, it is considered that the heat exchange unit 100 is abnormal, and the user can be reminded to perform maintenance and inspection on the heat exchange unit 100 in time; if the heat exchange efficiency of the heat exchange medium in the heat exchange component 10 with water is large through the heat meter 255, then the heat exchange unit 100 is not abnormal. It should be noted that the heat meter 255 can be an ultrasonic heat meter 255, etc.

[0065] Please combine Figure 2 and Figure 3 In some embodiments, a second pressure detector 257 is provided on a network return pipeline 25. The second pressure detector 257 is used to detect the pressure in a network return pipeline 25. That is, the second pressure detector 257 provided on a network return pipeline 25 can detect the pressure in a network return pipeline 25 in real time, and the second pressure detector 257 compares the real-time detected pressure in a network return pipeline 25 with the real-time detected pressure in a network supply pipeline 23 by the first pressure detector 234, that is, if the pressure in a network return pipeline 25 is slightly different from the pressure in a network supply pipeline 23, it means that the heat exchange component 10 is abnormal and needs to be repaired; if the pressure in a network return pipeline 25 is significantly different from the pressure in a network supply pipeline 23, it means that the heat exchange component 10 is not abnormal. It should be noted that the second pressure detector 257 can be a pressure gauge, a pressure transmitter, etc.

[0066] Please combine Figure 2 and Figure 3 In some embodiments, a first temperature detector 27 is disposed on a network supply and return pipeline 20. The first temperature detector 27 is used to detect the temperature in a network supply and return pipeline 20.

[0067] Specifically, the first temperature detector 27 can be respectively arranged on a network supply pipeline 23 and a network return pipeline 25. The first temperature detector 27 arranged on a network supply pipeline 23 can detect the temperature of the heat exchange medium flowing through the network supply pipeline 23 in real time, and the first temperature detector 27 arranged on a network return pipeline 25 can detect the temperature of the heat exchange medium flowing through the network return pipeline 25 in real time, so as to compare and analyze the temperature of the heat exchange medium flowing through the network supply pipeline 23 with the temperature of the heat exchange medium flowing through the network return pipeline 25, that is, if the temperature of the heat exchange medium flowing through the network supply pipeline 23 is slightly different from the temperature of the heat exchange medium flowing through the network return pipeline 25, it means that the heat exchange component 10 is abnormal and needs to be repaired; if the temperature of the heat exchange medium flowing through the network supply pipeline 23 is significantly different from the temperature of the heat exchange medium flowing through the network return pipeline 25, it means that the heat exchange component 10 is not abnormal.

[0068] In some embodiments, a first temperature gauge 29 is disposed on a network supply and return pipeline 20 , and the first temperature gauge 29 is used to display the temperature in the network supply and return pipeline 20 .

[0069] Specifically, the first thermometer 29 can be respectively arranged on a network supply pipeline 23 and a network return pipeline 25. The first thermometer 29 arranged on the network supply pipeline 23 can display the temperature of the heat exchange medium flowing through the network supply pipeline 23 in real time, and the first thermometer 29 arranged on the network return pipeline 25 can display the temperature of the heat exchange medium flowing through the network return pipeline 25 in real time, so that the user can compare and analyze the temperature of the heat exchange medium flowing through the network supply pipeline 23 and the temperature of the heat exchange medium flowing through the network return pipeline 25 through the first thermometer 29, that is, if the temperature of the heat exchange medium flowing through the network supply pipeline 23 is slightly different from the temperature of the heat exchange medium flowing through the network return pipeline 25, it means that the heat exchange component 10 is abnormal and needs to be repaired; if the temperature of the heat exchange medium flowing through the network supply pipeline 23 is significantly different from the temperature of the heat exchange medium flowing through the network return pipeline 25, it means that the heat exchange component 10 is not abnormal.

[0070] See also Figure 4 In some embodiments, the heat exchange unit 100 further includes a second straight pipe 40 and a second network supply and return pipeline 50. The heat exchange component 10 further includes a water side. Water is stored in the second network supply and return pipeline 50. The second straight pipe 40 connects the second network supply and return pipeline 50 and the water side of the heat exchange component 10.

[0071] Specifically, one end of the second straight pipe 40 can be connected to the water side of the heat exchange component 10 by screwing or welding, and the other end of the second straight pipe 40 can be connected to the second network supply and return pipeline 50 by screwing or welding, so that the water flowing from the second network supply and return pipeline 50 through the second straight pipe 40 and entering the water side of the heat exchange component 10 is subject to an operating resistance not higher than 50 kPa. The overall transmission, heat transfer, heat exchange and energy-saving efficiency of the heat exchanger unit 100 is high, the operating energy consumption is low, and the energy-saving efficiency of the heat exchanger unit 100 can be improved by 10% to 20%.

[0072] When the heat exchange unit 100 is working, water can flow from the second network supply and return pipeline 50 through the second straight pipe 40 into the water side of the heat exchange component 10, and exchange heat with the heat exchange medium in the heat exchange medium side of the heat exchange component 10 to vaporize water into warm air.

[0073] It should be noted that the second straight tube 40 can be made of metal, that is, the second straight tube 40 can be made of, for example, aluminum alloy, so as to reduce the overall weight of the heat exchange unit 100 while increasing the rigidity of the second straight tube 40 and extending its service life.

[0074] In this way, since the volume and internal resistance of the second straight pipe 40 are relatively small, the second network supply and return pipeline 50 of the heat exchanger unit 100 of the present application is connected to the heat exchange medium side of the heat exchange component 10 through the second straight pipe 40, which can reduce the floor space of the heat exchanger unit 100, increase the flow rate of the heat exchange medium flowing into the heat exchange component 10, and will not occupy too much maintenance space of the heat exchanger unit 100. The maintenance space is relatively large, which is convenient for users to perform subsequent maintenance on the heat exchanger unit 100.

[0075] Please combine Figure 4 , Figure 5 and Figure 6 In some embodiments, the second network supply and return pipeline 50 includes a second network supply pipeline 51 and a second network return pipeline 52, the second network supply pipeline 51 is connected to the outlet end of the water side of the heat exchange component 10, and the second network return pipeline 52 is connected to the inlet end of the water side of the heat exchange component 10.

[0076] Specifically, one end of the second network supply pipeline 51 can be connected to the outlet end of the water side of the heat exchange component 10 through the second straight pipe 40 by screwing or welding, and the other end of the second network supply pipeline 51 can be connected to the user end so that the second network supply pipeline 51 supplies heating to the user end.

[0077] One end of the second network return pipeline 52 can be connected to the water supply end, and the other end of the second network return pipeline 52 can be connected to the inlet end of the water side of the heat exchange component 10 through the second straight pipe 40 by screwing or welding, so as to supply water to the heat exchange component 10 through the second network return pipeline 52 and the second straight pipe 40.

[0078] When the heat exchange unit 100 is working, water can enter the water side of the heat exchange component 10 from the inlet end of the water side of the heat exchange component 10 after passing through the second network return pipe 52 and the second straight pipe 40, and exchange heat with the heat exchange medium on the heat exchange medium side of the heat exchange component 10 to vaporize the water into warm air. Then, the warm air can flow out from the outlet end of the water side of the heat exchange component 10, and be supplied to the user end through the second straight pipe 40 connected to the second network supply pipe 51 and the second network supply pipe 51 in turn, and the cycle is repeated to continuously supply warm air to the user end.

[0079] Please combine Figure 5 and Figure 6 In some embodiments, a third shutoff switch 511 is provided on the second network supply pipeline 51. A fourth shutoff switch 521 is provided on the second network return pipeline 52. The third shutoff switch 511 is used to control the opening or closing of the second network supply pipeline 51, and the fourth shutoff switch 521 is used to control the opening or closing of the second network return pipeline 52.

[0080] Specifically, the third shutoff switch 511 can be arranged on the second network supply pipeline 51 by screwing or welding, so as to control the opening or closing of the second network supply pipeline 51 by the third shutoff switch 511, thereby ensuring the safe operation of the heat exchange unit 100. The fourth shutoff switch 521 can be arranged on the second network return pipeline 52 by screwing or welding, so as to control the opening or closing of the second network return pipeline 52 by the fourth shutoff switch 521, thereby ensuring the safe operation of the heat exchange unit 100. It should be noted that both the third shutoff switch 511 and the fourth shutoff switch 521 can be shutoff ball valves.

[0081] In one embodiment, when the heat exchanger unit 100 is working, the third shut-off switch 511 and the fourth shut-off switch 521 can be changed from open to closed, so that the second network supply pipeline 51 and the second network return pipeline 52 are opened. At this time, water can flow from the first network return pipeline 25 into the water side of the heat exchange component 10 to exchange heat with the heat exchange medium and vaporize into warm air. After that, it flows from the outlet end of the water side of the heat exchange component 10 through the second network supply pipeline 51 and is supplied to the user end for use.

[0082] In another embodiment, when it is necessary to stop supplying heating to the user end, the third shut-off switch 511 and the fourth shut-off switch 521 can be changed from closed to open to close the second network supply pipeline 51 and the second network return pipeline 52. At this time, water stops entering the water side of the heat exchange component 10 from the second network return pipeline 52, so that the heat exchange unit 100 stops supplying heating to the user end.

[0083] In some embodiments, a water meter 53 is provided on the secondary network supply and return pipeline 50, and the water meter 53 is used to display the flow rate in the secondary network supply and return pipeline 50. That is, the water meter 53 can be respectively provided on the secondary network supply pipeline 51 and the secondary network return pipeline 52. The water meter 53 provided on the secondary network supply pipeline 51 can be used to display the flow rate in the secondary network supply pipeline 51, so that the user can know the flow rate flowing into the client in time. The water meter 53 provided on the secondary network return pipeline 52 can be used to display the flow rate in the secondary network return pipeline 52, so that the user can know the water flow rate flowing into the water side of the heat exchange component 10 in time. It should be noted that the water meter 53 can be an ultrasonic water meter 53, etc.

[0084] See also Figure 6 In some embodiments, an electromagnetic wave water quality manager 526 and a plate-side ball valve 527 are also provided on the second network return pipeline 52. The electromagnetic wave water quality manager 526 is connected to the inlet end of the water side of the heat exchange component 10 through the plate-side ball valve 527. The electromagnetic wave water quality manager 526 is used to optimize the water quality of the water flowing through the second network return pipeline 52. The plate-side ball valve 527 is used to control the water flow rate flowing into the water side of the heat exchange component 10. That is, when the heat exchange unit 100 is working, the plate-side ball valve 527 can be opened. At this time, the water can be optimized by the electromagnetic wave water quality manager 526, and then flow out of the electromagnetic wave water quality manager 526 through the plate-side ball valve 527, and enter the water side of the heat exchange component 10 from the inlet end of the water side of the heat exchange component 10 to exchange heat with the heat exchange medium. It should be noted that the user can also control the opening and closing degree of the plate-side ball valve 527 according to actual application needs, thereby controlling the water flow rate flowing into the water side of the heat exchange component 10.

[0085] It can be understood that since the electromagnetic wave water quality manager 526 can effectively inhibit calcium and magnesium crystallization, sterilize and kill algae, physically flocculate, and prevent and remove scale, and the special pulse technology can generate a protective film of a metal salt layer, so that it adheres to the surface of the metal, it can slow down the surface corrosion time of the second network supply and return pipeline 50. Therefore, the present application can use electromagnetic pulse technology to generate a molecular force dynamic interference field on the pipeline of the second network supply and return pipeline 50, change the crystallization process of calcium and magnesium ions in the fluid, so that the scale loses its adhesion and is washed away by the water flow, thereby achieving the effect of preventing and removing scale, improving the heat exchange efficiency of the heat exchanger unit 100, and at the same time, a metal salt layer protective film can be formed on the pipeline of the second network supply and return pipeline 50 to slow down the pipeline corrosion of the second network supply and return pipeline 50.

[0086] Please combine Figure 1 , Figure 4 and Figure 6In some embodiments, the heat exchange unit 100 further includes a sewage main pipe 30. A second horizontal expansion and decontamination device 523 and a third sewage valve 524 are also provided on the second network return pipeline 52. One end of the third sewage valve 524 is connected to the second horizontal expansion and decontamination device 523, and the other end of the third sewage valve 524 is connected to the sewage main pipe 30. The second horizontal expansion and decontamination device 523 is used to filter the impurities in the water. The third sewage valve 524 is used to discharge the impurities to the sewage main pipe 30.

[0087] Specifically, the second horizontal expansion filter 523 can be set on the second network loop pipeline 52 by screwing or welding, and is located between the fourth shut-off switch 521 and the third drain valve 524, so as to filter out debris in the water through the second horizontal expansion filter 523 to prevent the debris in the water from flowing into the water side of the heat exchange component 10 with the water.

[0088] One end of the third sewage valve 524 can be connected to the second horizontal expansion sewage separator 523 by screwing or welding, and the other end of the third sewage valve 524 can be connected to the sewage main pipe 30 by screwing or welding, so that after the second horizontal expansion sewage separator 523 filters out the debris in the water, the third sewage valve 524 is opened to discharge the debris from the second network return pipeline 52 into the sewage main pipe 30.

[0089] It should be noted that the third drain valve 524 can be a wafer-type thin ball valve. The second horizontal expansion decontaminant 523 has a good filtering effect, and the built-in filter screen of the second horizontal expansion decontaminant 523 is convenient to disassemble and wash, so the maintenance cost of the second horizontal expansion decontaminant 523 is low when the application is maintained later.

[0090] The secondary network supply and return pipeline 50 can be directly connected to the heat exchange component 10 through the second straight pipe 40 before leaving the factory, and then the heat exchanger unit 100 can be transported as a whole. Therefore, there is no need to assemble the heat exchanger unit 100 on site, the construction difficulty is relatively small, the efficiency is relatively high, the cost is relatively low, and the ability requirements for the construction team are relatively low, and it can be supplied in batches as a whole set.

[0091] When the heat exchange unit 100 is working, the water can pass through the second horizontal expansion filter 523 to filter the impurities in the heat exchange medium. At this time, the third drain valve 524 can be opened to discharge the impurities from the second network return pipeline 52 to the main drain pipe 30. Then, the filtered water can pass through the second network return pipeline 52 and the second straight pipe 40, and enter the water side of the heat exchange component 10 from the inlet end of the water side of the heat exchange component 10 to exchange heat with the heat exchange medium on the heat exchange medium side of the heat exchange component 10.

[0092] See also Figure 6In some embodiments, a third pressure detector 525 is provided at both ends of the second horizontal expansion and decontamination device 523 , and the third pressure detector 525 is used to detect the pressure change at both ends of the second horizontal expansion and decontamination device 523 .

[0093] Specifically, Figure 6 As shown, the number of the third pressure detectors 525 can be two, one of the third pressure detectors 525 can be set at one end of the second horizontal expansion and decontamination device 523, and the other third pressure detector 525 can be set at the other end of the second horizontal expansion and decontamination device 523, so as to observe the pressure value change between the water before filtration and the water after filtration through the two second pressure detectors 257, that is, if the pressure value change between the water before filtration and the water after filtration observed by the two third pressure detectors 525 is within the predetermined pressure range, it means that there is no abnormality in the second horizontal expansion and decontamination device 523; if the pressure value change between the water before filtration and the water after filtration observed by the two third pressure detectors 525 is not within the predetermined pressure range, it means that the second horizontal expansion and decontamination device 523 has an abnormality, and the user can be reminded to perform maintenance and inspection on the second horizontal expansion and decontamination device 523 in time.

[0094] It should be noted that Figure 6 The two second pressure detectors 257 provided on the second horizontal expansion and decontamination device 523 are shown in the figure for illustration only. The number of the second pressure detectors 257 provided on the second horizontal expansion and decontamination device 523 may be, for example, 3, 4, 5, 6, 7 or 8, which is not limited here. The predetermined pressure range may be, for example, 0.03Mpa to 1.6Mpa. The third pressure detector 525 may be a pressure gauge and a pressure transmitter.

[0095] See also Figure 6 In some embodiments, the secondary network supply and return pipeline 50 further includes a circulating water pump 54 and a rubber hose 55. The circulating water pump 54 is arranged on the secondary network return pipeline 52 through the rubber hose 55.

[0096] Specifically, the rubber hose 55 can be arranged at both ends of the circulating water pump 54 by means of a snap-fitting manner. One end of the circulating water pump 54 can be connected to the second horizontal expansion and decontamination device 523 through the rubber hose 55, and the other end of the circulating water pump 54 can be connected to the main pipeline of the second network return pipeline 52 through the rubber hose 55. It should be noted that, since the rubber hose 55 has the ability of shock reduction and noise reduction, and has a strong vibration absorption ability, therefore, the circulating water pump 54 of the present application is arranged on the second network return pipeline 52 through the rubber hose 55, which can reduce the noise of the circulating water pump 54 when it is working.

[0097] When the heat exchanger unit 100 is working, the circulating water pump 54 can drive water to circulate repeatedly between the water supply end, the secondary network return pipeline 52, the water side of the heat exchange component 10, the secondary network supply pipeline 51 and the user end, overcoming the resistance loss of the secondary network supply and return pipeline 50, so that the heat exchanger unit 100 can operate stably.

[0098] See also Figure 5 and Figure 6 In some embodiments, a bypass pipe 513 is further provided on the second network supply pipeline 51, and a second bypass switch 522 is provided on the second network return pipeline 52. The bypass pipe 513 is connected to the second bypass switch 522.

[0099] Specifically, one end of the bypass pipe 513 can be connected to the main pipe of the second network supply pipeline 51 by screwing or welding, and the other end of the bypass pipe 513 can be connected to one end of the second bypass switch 522 by welding or screwing, and the other end of the second bypass switch 522 can be set on the main pipe of the second network return pipeline 52 by screwing or welding.

[0100] When the heat exchanger 100 operates normally, the second bypass switch 522 can be always in the closed state. Before the heat exchanger 100 stops working, the second bypass switch 522 can be changed from closed to open, and the plate-side ball valve 527 can be closed to allow the heat exchanger 100 to enter the cold cycle. After the heat exchanger 100 stops working, the second bypass switch 522 can be changed from closed to open, and the plate-side ball valve 527 can be closed, and the water flow can flush the secondary network supply and return pipeline 50.

[0101] See also Figure 5 In some embodiments, a fourth pressure detector 515 is provided on the second network supply pipeline 51. The fourth pressure detector 515 is used to detect the pressure in the second network supply pipeline 51. That is, the fourth pressure detector 515 provided on the second network supply pipeline 51 can detect the pressure in the second network supply pipeline 51 in real time, so as to compare the real-time detected pressure in the second network supply pipeline 51 through the fourth pressure detector 515 with the real-time detected pressure in the second network return pipeline 52 by the third pressure detector 525, that is, if the pressure in the second network supply pipeline 51 is slightly different from the pressure in the second network return pipeline 52, it means that the heat exchange component 10 is abnormal and needs to be repaired; if the pressure in the second network supply pipeline 51 is significantly different from the pressure in the second network return pipeline 52, it means that the heat exchange component 10 is not abnormal. It should be noted that the fourth pressure detector 515 can be a pressure gauge, a pressure transmitter, etc.

[0102] Please combine Figure 4 and Figure 6In some embodiments, the heat exchanger unit 100 further includes a water replenishment component 60. The water replenishment component 60 is connected to the second network return pipeline 52, and the water replenishment component 60 is used to replenish water for the second network return pipeline 52 when the water flow rate flowing through the second network return pipeline 52 is insufficient. That is, one end of the water replenishment component 60 can be connected to the second network return pipeline 52 by screwing or welding, and the other end of the water replenishment component 60 can be connected to an external water tank or a municipal tap water system. When the water flow rate of the main pipeline of the second network return pipeline 52 is insufficient, the water in the external water tank or the municipal tap water system can flow into the main pipeline of the second network return pipeline 52 through the water replenishment component 60 to replenish the second network return pipeline 52 with water.

[0103] Please combine Figure 5 and Figure 6 In some embodiments, a second temperature detector 56 is provided on the secondary network supply and return pipeline 50 , and the second temperature detector 56 is used to detect the temperature in the secondary network supply and return pipeline 50 .

[0104] Specifically, the second temperature detector 56 can be respectively arranged on the second network supply pipeline 51 and the second network return pipeline 52. The second temperature detector 56 arranged on the second network supply pipeline 51 can detect the temperature in the second network supply pipeline 51 in real time, and the second temperature detector 56 arranged on the second network return pipeline 52 can detect the temperature in the second network return pipeline 52 in real time, so as to compare and analyze the temperature in the second network supply pipeline 51 with the temperature in the second network return pipeline 52, that is, if the temperature in the second network supply pipeline 51 is slightly different from the temperature in the second network return pipeline 52, it means that the heat exchange component 10 is abnormal and needs to be repaired; if the temperature in the second network supply pipeline 51 is significantly different from the temperature flowing through the second network return pipeline 52, it means that the heat exchange component 10 is not abnormal. It should be noted that the second temperature detector 56 can be a temperature sensor, etc.

[0105] In some embodiments, a second temperature gauge 57 is disposed on the secondary network supply and return pipeline 50 , and the second temperature gauge 57 is used to display the temperature in the secondary network supply and return pipeline 50 .

[0106] Specifically, the second thermometer 57 can be respectively arranged on the second network supply pipeline 51 and the second network return pipeline 52. The second thermometer 57 arranged on the second network supply pipeline 51 can display the temperature flowing through the second network supply pipeline 51 in real time, and the second thermometer 57 arranged on the second network return pipeline 52 can display the temperature flowing through the first network return pipeline 25 in real time, so that the user can compare and analyze the temperature in the second network supply pipeline 51 and the temperature in the second network return pipeline 52 through the second thermometer 57, that is, if the temperature in the second network supply pipeline 51 is slightly different from the temperature in the second network return pipeline 52, it means that the heat exchange component 10 is abnormal and needs to be repaired; if the temperature in the second network supply pipeline 51 is significantly different from the temperature in the second network return pipeline 52, it means that the heat exchange component 10 is not abnormal.

[0107] Please combine Figure 6 and Figure 7 In some embodiments, the water replenishment assembly 60 includes a shutoff reducer 61 and a check valve 63. A water replenishment switch 528, a drainage switch 529, a right-angle elbow 5281 and a water meter 53 are also provided on the second network return pipeline 52. One end of the water replenishment switch 528 is connected to the second horizontal expansion and decontamination device 523. The other end of the water replenishment switch 528 is connected to the first end of the right-angle elbow 5281. The drainage switch 529 is connected to the second end of the right-angle elbow 5281. One end of the water meter 53 is connected to the third end of the right-angle elbow 5281. The other end of the water meter 53 is connected to one end of the check valve 63. The other end of the check valve 63 is connected to the shutoff reducer 61.

[0108] Specifically, one end of the water replenishment switch 528 can be connected to the second horizontal expansion decontaminant 523 by welding or screw connection. The other end of the water replenishment switch 528 can be connected to the first end 52811 of the right-angle elbow 5281 by welding or screw connection. The drainage switch 529 can be connected to the second end 52812 of the right-angle elbow 5281 by welding or screw connection. One end of the water meter 53 can be connected to the third end 52813 of the right-angle elbow 5281 by welding or screw connection. One end of the check valve 63 can be connected to the other end of the water meter 53 by welding or screw connection through a steel pipe 631. The other end of the check valve 63 can be connected to one end of the shut-off reducer 61 by welding or screw connection. The other end of the shut-off reducer 61 can be connected to an external water tank or a municipal tap water system.

[0109] When the water flow in the main pipeline of the second network return pipeline 52 is insufficient, the shut-off reducer 61 and the water replenishment switch 528 can be opened, so that the water from the external water tank or the municipal tap water system can flow into the second horizontal expansion and decontamination device 523 through the shut-off reducer 61, the check valve 63, the steel pipe 631 of the check valve 63, the water meter 53, the right-angle elbow 5281 and the water replenishment switch 528 in sequence to replenish the main pipeline of the second network return pipeline 52.

[0110] It should be noted that when the water flow in the main pipeline of the second network return pipeline 52 is saturated, the drain switch 529 can be turned on, and the excess water can be discharged through the drain switch 529. The water meter 53 can display the water flow flowing into the right-angle elbow 5281 in real time, so that the user can know the water flow added to the main pipeline of the second network loop in real time. Since the check valve 63 has the function of limiting the direction of water flow, the present application can prevent water from flowing back from the second network return pipeline 52 to the external water tank or the municipal tap water system by setting a check valve 63 between the water meter 53 and the shut-off reducer 61. The water replenishment switch 528 can be a water replenishment ball valve. The drain switch 529 can be a small drain ball valve.

[0111] It can be understood that compared with connecting the water supply switch 528, the drainage switch 529 and the water meter 53 through a bend pipe with a larger bending angle, the present application connects the water supply switch 528, the drainage switch 529 and the water meter 53 through a right-angle bend pipe 5281, which occupies less space and has a more beautiful overall appearance.

[0112] In addition, in actual applications, if any one of the shut-off reducer switch 61 and the water replenishment switch 528 is damaged, the other one can also control the opening and closing of the water replenishment component 60, and can also ensure the normal operation of the water replenishment component 60 to replenish the main pipeline of the second network return pipeline 52 with water. Therefore, the water replenishment component 60 of the present application operates more stably.

[0113] Please combine Figure 6 and Figure 7 In some embodiments, the water replenishment assembly 60 further includes a water replenishment rubber hose 65 and a water replenishment pump 67, one end of the water replenishment pump 67 is connected to the shutoff variable diameter switch 61, and the other end of the water replenishment pump 67 is connected to the check valve 63 through the water replenishment rubber hose 65. That is, one end of the water replenishment pump 67 can be connected to the shutoff variable diameter switch 61 by welding or screw connection, and the other end of the water replenishment pump 67 can be connected to the check valve 63 by screw connection or clamping through the water replenishment rubber hose 65.

[0114] In one embodiment, when the water flow in the main pipeline of the second network loop pipeline 52 is insufficient and the shut-off reducer 61 and the water replenishment switch 528 are turned on, the water replenishment pump 67 can drive water from an external water tank or a municipal tap water system, through the shut-off reducer 61, the check valve 63, the steel pipe 631 of the check valve 63, the water meter 53, the right-angle elbow 5281 and the water replenishment switch 528 in sequence, and flow into the second horizontal expansion and decontamination device 523 to replenish water in the main pipeline of the second network loop pipeline 52.

[0115] It should be noted that the water replenishment pump 67 can also be used to drive the water replenishment component 60 to replenish water to the second network supply and return pipeline 50 for constant pressure when the heat exchanger unit 100 is working, and before the initial operation of the heat exchanger unit 100, the water replenishment pump 67 can drive the water replenishment component 60 to inject water into the second network supply and return pipeline 50 to pressurize it and observe whether there is damage or leakage in the second network supply and return pipeline 50, that is, if there is damage or leakage in the second network supply and return pipeline 50, the user can be reminded to perform maintenance in time. The water replenishment pump 67 can also drive the water replenishment component 60 to replenish the second network supply and return pipeline 50 when the water is lost due to system leakage or maintenance during the operation of the heat exchanger unit 100.

[0116] Since the water supply rubber hose 65 has the ability to reduce shock and noise and has strong vibration absorption ability, the other end of the water supply pump 67 of the present application is connected to the check valve 63 through the water supply rubber hose 65, which can reduce the noise of the circulating water pump 54 when it is working.

[0117] In addition, the other end of the water replenishment pump 67 of the present application is connected to the check valve 63 through the water replenishment rubber hose 65, and the check valve 63 can prevent high-pressure water from flowing back into the water pump, causing the water pump impeller or other components to loosen or be damaged due to the impact of hydraulic force.

[0118] Please combine Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 In some embodiments, the heat exchange unit 100 further includes a sewage discharge component 70, and the sewage main pipe 30 is connected to the first sewage valve 233, the second sewage valve 253 and the third sewage valve 524 respectively through the sewage discharge component 70.

[0119] Specifically, Figure 8 As shown, the sewage discharge assembly 70 may include a network supply sewage discharge member 71, a network return sewage discharge member 73 and a second network return sewage discharge member 75. One end of the network supply sewage discharge member 71 may be connected to the first sewage discharge valve 233 by welding or screwing, and the other end of the network supply sewage discharge member 71 may be connected to the sewage main pipe 30 by welding or screwing, so as to integrate the sewage discharge connection point of the network supply pipeline 23 on the sewage main pipe 30.

[0120] One end of a network return sewage discharge part 73 can be connected to the second sewage valve 253 by welding or screwing, and the other end of a network return sewage discharge part 73 can be connected to the sewage main pipe 30 by welding or screwing, so as to integrate the drainage connection point of a network return pipeline 25 on the sewage main pipe 30.

[0121] One end of the second-network sewage discharge component 75 can be connected to the third sewage valve 524 by welding or screwing, and the other end of the second-network sewage discharge component 75 can be connected to the sewage main pipe 30 by welding or screwing, so as to integrate the sewage connection point of the second-network return pipeline 52 on the sewage main pipe 30.

[0122] When it is necessary to discharge the debris and accumulated water, the first drain valve 233, the second drain valve 253 and the third drain valve 524 can be opened respectively, so that the debris in the first network supply pipeline 23 is discharged into the sewage main pipe 30 through the first drain valve 233 and the first network supply sewage discharge component 71, the accumulated water in the first network return pipeline 25 is discharged into the sewage main pipe 30 through the second drain valve 253 and the first network return sewage discharge component 73, and the debris in the second network return pipeline 52 is discharged into the sewage main pipe 30 through the third drain valve 524 and the second network return sewage discharge component 75, and then the debris is discharged to the municipal pipeline network through the sewage main pipe 30.

[0123] It should be noted that the pipe material of the sewage assembly 70 can be made of PPr material. That is, since the production cost of PPr material is low, the pipe material of the sewage assembly 70 of the present application is made of PPr material, the production cost is low, and it is convenient to disassemble and assemble. The outlet end of the sewage main pipe 30 can be connected to a sewage trench dug in advance and lead to the outdoors or the municipal pipe network, which is not limited here.

[0124] In this way, the sewage main pipe 30 of the heat exchanger unit 100 of the present application is connected to the first sewage valve 233, the second sewage valve 253 and the third sewage valve 524 respectively through the sewage assembly 70, and the sewage connection point of the first network supply pipeline 23, the drainage connection point of the first network return pipeline 25 and the sewage connection point of the second network return pipeline 52 are integrated into the sewage main pipe 30, the production cost is low, and the pipeline layout design is relatively simple and reasonable.

[0125] See also Figure 8 In some embodiments, the heat exchange unit 100 further includes a pressure relief component 80 , which is disposed on the sewage discharge component 70 , and is used to relieve pressure on the sewage discharge component 70 .

[0126] Specifically, the pressure relief assembly 80 may include a solenoid valve 81, a filter ball valve 83, and a pressure relief pipe 85. One end of the pressure relief pipe 85 may be disposed on the sewage discharge assembly 70 by welding or screwing. The other end of the pressure relief pipe 85 may be connected to the filter ball valve 83 by welding or screwing. The solenoid valve 81 may be disposed on the pressure relief pipe 85 by screwing or snapping.

[0127] When the pressure in the sewage discharge assembly 70 is too high, the electromagnetic valve 81 and the filter ball valve 83 can be remotely controlled to open by communication, and the pressure in the sewage discharge assembly 70 can be relieved through the pressure relief pipe 85. It should be noted that since the pressure relief assembly 80 has the characteristics of small size, low power and high upper limit of the pressure range, the user can install the pressure relief assembly 80 at any pipeline position of the heat exchange unit 100 according to the needs of actual application.

[0128] See also Figure 4 In some embodiments, the heat exchange assembly 10 includes a heat exchanger 11 and a detachable split insulation shell 13. The detachable split insulation shell 13 is covered on the heat exchanger 11. That is, the detachable split insulation shell 13 can be composed of a plurality of sheet metals with built-in insulation materials. The detachable split insulation shell 13 can be detachably covered on the heat exchanger 11 by snapping or screwing to insulate the heat exchanger 11.

[0129] It can be understood that since the detachable split insulation shell 13 of the present application is composed of a plurality of sheet metals with built-in insulation materials, when transporting the heat exchanger unit 100, the detachable split insulation shell 13 can be removed from the heat exchanger 11 in sections, which is convenient for disassembly and transportation, and has a better insulation effect.

[0130] In some embodiments, the heat exchange unit 100 further includes a data terminal box 90. The data terminal box 90 is electrically connected to the first pressure detector 234, the first temperature detector 27, the second pressure detector 257, the third pressure detector 525, the fourth pressure detector 515 and the second temperature detector 56 respectively. That is, the present application can collect the pressure in the first network supply pipeline 23 detected by the first pressure detector 234, the temperature of the first network supply return pipeline 20 detected by the first temperature detector 27, the pressure in the first network return pipeline 25 detected by the second pressure detector 257, the pressure in the second network return pipeline 52 detected by the third pressure detector 525, the pressure in the second network supply pipeline 51 detected by the fourth pressure detector 515, and the temperature in the second network supply return pipeline 50 detected by the second temperature detector 56 through the data terminal box 90, and then the data terminal box 90 centrally uploads the pressure data and temperature data to the system software platform, so as to realize the centralized and accurate collection of the operation data of the heat exchanger unit 100, ensure the uniformity of the equipment protocol standard, and the system software platform can be seamlessly connected with the heat exchanger unit 100 and controlled in real time, without the need for personnel on duty, saving manpower. It should be noted that the data terminal box 90 can be an intelligent IoT data terminal box 90.

[0131] In addition, the heat exchanger unit 100 of the present application can respond quickly according to actual user needs and replace parts in the heat exchanger unit 100 to meet user needs.

[0132] The present application also provides a heating system. The heating system includes the heat exchange unit 100 of any of the above embodiments. The specific structure of the heat exchange unit 100 is as described above, and for the sake of brevity, it will not be repeated here.

[0133] In this way, since the volume and internal resistance of the first straight pipe 21 are relatively small, the supply and return pipeline 20 of the heating system of the present application is connected to the heat exchange medium side of the heat exchange component 10 through the first straight pipe 21, which can reduce the space occupied by the heat exchange unit 100, increase the flow rate of the heat exchange medium flowing into the heat exchange component 10, and will not occupy too much maintenance space of the heat exchange unit 100. The maintenance space is relatively large, which is convenient for users to perform subsequent maintenance on the heat exchange unit 100.

[0134] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
