Description

Technical Field

[0001] This application relates to the field of emission cooling, and in particular to an emission device with a cooling function. Background Technology

[0002] In the operation of a heating network, hot water discharge is an indispensable part. After completing heat transfer and supplying the required heat energy to users, the hot water in the heating network is discharged at a certain temperature. This process relies on a carefully designed pipeline network and precise control devices to ensure that the discharge is carried out in an orderly manner. The smoothness of hot water discharge directly affects the continuous and stable operation of the heating network. A scientific discharge design can effectively maintain the pressure balance and thermal circulation of the network system, ensuring the efficient operation of the entire heating system.

[0003] In the operation of heating pipe networks, the discharge of hot water is a critical aspect that needs to be handled properly. Although the temperature of hot water in the heating pipe network decreases after heat exchange, it still carries a high level of residual heat. If discharged directly, its high temperature will cause damage to the soil and the surrounding environment, and the generated hot air can easily injure nearby people. Summary of the Invention

[0004] To address the technical problem of thermal pollution caused by hot water discharge from heating pipe networks, this application provides a discharge device with a cooling function.

[0005] The emission device with cooling function provided in this application adopts the following technical solution:

[0006] A cooling discharge device includes a heat exchange cylinder. Both ends of the heat exchange cylinder are provided with sealing plates. A water inlet pipe is connected to the top of one sealing plate, and a water outlet pipe is connected to the bottom of the other sealing plate. Several heat dissipation fins are provided on the outer side of the heat exchange cylinder at equal intervals. Several hollow tubes are fixedly connected between the two sealing plates, and both ends of the hollow tubes are open. A support frame for supporting the heat exchange cylinder is provided at the bottom of the heat exchange cylinder.

[0007] By adopting the above technical solution, hot water flows into the heat exchange cylinder from the inlet pipe and flows to the bottom of the heat exchange cylinder, and finally is discharged along the outlet pipe. When the hot water flows in the heat exchange cylinder, the external heat dissipation fins can fully absorb heat and dissipate it, thereby achieving the effect of reducing the temperature. Moreover, the hollow tube can achieve the effect of cooling through airflow, further improving the heat dissipation capacity of the middle part of the heat exchange cylinder.

[0008] Preferably, the heat dissipation fins are provided with crests and troughs, and the crests and troughs of adjacent heat dissipation fins are staggered.

[0009] By adopting the above technical solution, the crests and troughs of the heat dissipation fins are staggered between adjacent heat dissipation fins. When the airflow in the external environment is not in the same direction as the heat dissipation fins, the airflow blowing effect on the crest of each heat dissipation fin can be improved, the heat accumulation caused by the crowding of heat dissipation fins can be reduced, thereby improving the cooling effect.

[0010] Preferably, a guide cover is fixed on the sealing plate, and the guide cover is opened to one side of the sealing plate. One end of the guide cover is located at the end of one of the hollow tubes. A sliding hole is opened on the sealing plate, and a moving tube is slidably arranged in the sliding hole. A baffle is fixed to the outer end of the moving tube, and a pressure spring is arranged on the side of the baffle away from the moving tube. The other end of the pressure spring abuts against the inner wall of the guide cover. An air outlet is opened on the side wall of the moving tube near the baffle, and a through hole is opened on the side wall of the moving tube away from the baffle.

[0011] By adopting the above technical solution, when hot water passes through the heat exchange cylinder, water vapor will inevitably be generated. When the water vapor occupies the upper part of the heat exchange cylinder, the hot water cannot contact the upper inner wall of the heat exchange cylinder, and the heat dissipation effect of the corresponding heat dissipation fins in this part is not fully utilized. When the water vapor increases, the internal air pressure of the heat exchange cylinder increases. At this time, the moving tube is pushed outward and overcomes the elastic force of the pressure spring. Then the moving tube moves outward. When the vent moves to the outside of the sealing plate, the water vapor can be discharged into one of the hollow tubes through the through hole, the moving tube, the vent, and the guide cover, thereby preventing the accumulation of too much gas inside the heat exchange cylinder and allowing the upper heat dissipation fins to fully exert their heat dissipation effect.

[0012] Preferably, a sliding sleeve is fixed to the inner side of the sealing plate, and the sliding sleeve is located directly below the moving tube. A limit pin is slidably arranged in the sliding sleeve, and a float plate is fixed on the limit pin. An insertion hole is opened on the lower side wall of the moving tube, and the insertion hole is located directly above the limit pin.

[0013] By adopting the above technical solution, when the heat exchange cylinder is filled with hot water, the buoyancy of the float plate will drive the limit pin to move upward and insert into the insertion hole, preventing the moving pipe from moving outward under water pressure, thereby maintaining the seal of the heat exchange cylinder and preventing hot water from flowing out.

[0014] Preferably, the guide cover has two symmetrically distributed connecting ear plates on both sides, and the connecting ear plates are detachably fixed to the sealing plate by bolts, and a safety plate is fixed at the end of the moving tube away from the baffle.

[0015] By adopting the above technical solution, when the guide cover is removed, the moving tube will move outward under the pressure of gas or hot water. At this time, the safety plate will directly adhere to the inner wall of the sealing plate to block the sliding hole and prevent hot water or hot steam from spraying out and injuring people when the guide cover is accidentally removed.

[0016] Preferably, both the baffle and the safety plate are provided with sealing gaskets on the side near the sealing plate.

[0017] By adopting the above technical solution, the sealing gasket can improve the sealing effect between the baffle and the safety plate and the sealing plate, and prevent water leakage.

[0018] Preferably, the water inlet pipe is connected to a thin tube that is sealed at one end. The thin tube is located inside the heat exchange cylinder, and several water spray holes are provided on the upper side wall of the thin tube.

[0019] By adopting the above technical solution, when hot water enters the thin tube from the inlet pipe, the pressure increases. At this time, the hot water will be sprayed upward through the spray hole, so that the hot water can contact the top of the heat exchange cylinder. This allows the heat dissipation fins at the top to fully exert their heat dissipation function even when there is less hot water inside the heat exchange cylinder.

[0020] Preferably, the spray holes are evenly spaced, and the diameter of the spray holes gradually increases along the direction away from the water inlet pipe.

[0021] By adopting the above technical solution, the change in orifice diameter can limit the excessive discharge of hot water into the spray holes near the inlet pipe, which would result in excessively low pressure in the subsequent spray holes and prevent them from contacting the top inner wall of the heat exchange cylinder. This ensures the uniformity of contact between the hot water and the inner wall of the heat exchange cylinder, thereby improving the cooling effect.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When hot water passes through the heat exchange cylinder, it flows from top to bottom and makes good contact with the cylinder wall. It can make full use of the heat dissipation fins on the outside for heat dissipation and cooling. Moreover, when there is a lot of hot water, the airflow inside the hollow tube can directly dissipate heat to the hot water inside, increasing the heat dissipation area of ​​the hot water, thereby improving the heat dissipation effect and cooling effect, reducing the temperature during discharge, and improving safety.

[0031] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0032] This application discloses an exhaust device with a cooling function.

[0033] Example 1:

[0034] Reference Figure 1 and Figure 2 A cooling discharge device includes a heat exchange cylinder 1, with sealing plates 2 installed at both ends of the heat exchange cylinder 1. A water inlet pipe 3 is connected above one of the sealing plates 2, and a water outlet pipe 4 is connected below the other sealing plate 2. Several heat dissipation fins 5 are evenly and equally spaced on the outer side of the heat exchange cylinder 1. Several hollow pipes 6 with open ends are fixedly connected between the two sealing plates 2. In addition, a support frame 7 is provided below the heat exchange cylinder 1 to support the heat exchange cylinder 1.

[0035] With the above configuration, when hot water flows into the heat exchange cylinder 1 from the inlet pipe 3, it flows along the inside of the cylinder to the bottom and then exits through the outlet pipe 4. During the flow of hot water within the heat exchange cylinder 1, the heat dissipation fins 5 on the outside of the cylinder can fully absorb the heat transferred from the hot water and dissipate it into the surrounding environment, thereby reducing the temperature of the hot water. Simultaneously, the hollow pipe 6 fixed between the two sealing plates 2 inside the heat exchange cylinder 1 allows airflow to pass through, further carrying away heat and effectively improving the heat dissipation capacity of the middle section of the heat exchange cylinder 1.

[0036] The implementation principle of this embodiment is as follows: through the hollow tube 6, a channel for airflow is formed inside the heat exchange cylinder 1. When there is a lot of hot water, heat can be dissipated from inside the hot water, thereby improving the heat dissipation and cooling effect.

[0037] Example 2:

[0038] refer to Figure 5 Two connecting lugs 22 are symmetrically arranged on both sides of the guide cover 10. The connecting lugs 22 can be detachably fixed to the sealing plate 2 using bolts. The guide cover 10 is open on the side facing the sealing plate 2, and its end corresponds to the end of one of the hollow tubes 6. A sliding hole 11 is provided on the sealing plate 2, and a moving tube 12 is slidably installed in the sliding hole 11. A baffle 13 is fixedly connected to the outer end of the moving tube 12, and a safety plate 21 is fixed to the other end. Sealing gaskets are installed on the side of the baffle 13 and the safety plate 21 near the sealing plate 2. A pressure spring 14 is provided on the side of the baffle 13 away from the moving tube 12, and the other end of the pressure spring 14 abuts against the inner wall of the guide cover 10. An air vent 15 is provided on the side wall of the moving tube 12 near the baffle 13, and a through hole 16 is provided on the side wall away from the baffle 13.

[0039] With the above setup, water vapor is inevitably generated when hot water flows through the heat exchange cylinder 1. As the water vapor gradually occupies the upper part of the heat exchange cylinder 1, the hot water cannot contact the inner wall of that part, resulting in the heat dissipation efficiency of the corresponding heat dissipation fins 5 not being fully utilized. As the water vapor continues to increase, the internal air pressure of the heat exchange cylinder 1 rises accordingly. At this time, the moving tube 12 will be pushed outward and move outward against the elastic force of the pressure spring 14. When the vent 15 on the moving tube 12 moves to the outside of the sealing plate 2, the water vapor can enter the moving tube 12 through the through hole 16, and then be discharged into one of the hollow tubes 6 through the vent 15 and the guide cover 10, thereby preventing excessive gas accumulation inside the heat exchange cylinder 1 and ensuring that the upper heat dissipation fins 5 can also effectively dissipate heat. In addition, if the guide cover 10 is removed, the moving tube 12 will continue to move outward due to the pressure of gas or hot water. At this time, the safety plate 21 will fit tightly against the inner wall of the sealing plate 2, blocking the sliding hole 11 and preventing hot water or hot steam from spraying out and injuring people when the guide cover 10 is accidentally removed.

[0040] Reference Figure 5 A sliding sleeve 17 is fixedly installed on the inner side of the sealing plate 2, and the sliding sleeve 17 is positioned directly below the moving tube 12. A limit pin 18 is slidably installed inside the sliding sleeve 17, and a float plate 19 is fixedly connected to the limit pin 18. At the same time, an insertion hole 20 is opened on the lower side wall of the moving tube 12, and the insertion hole 20 is positioned directly above the limit pin 18.

[0041] With the above settings, when the heat exchange cylinder 1 is filled with hot water, the buoyancy of the float plate 19 will drive the limit pin 18 to move upward and insert into the insertion hole 20, preventing the moving pipe 12 from moving outward under water pressure, thereby maintaining the seal of the heat exchange cylinder 1 and preventing hot water from flowing out.

[0042] refer to Figure 3 and Figure 4 The heat dissipation fins 5 are provided with crests 9 and troughs 8, and the crests 9 and troughs 8 of adjacent heat dissipation fins 5 are staggered.

[0043] With the above arrangement, the crests 9 and troughs 8 are staggered, increasing the distance between the crests 9. When the airflow direction in the external environment is not consistent with the arrangement direction of the heat dissipation fins 5, the airflow force on the crests 9 of each heat dissipation fin 5 can be enhanced, effectively avoiding the problem of heat accumulation caused by the heat dissipation fins 5 being too dense and crowded, thereby improving the cooling effect of the entire device.

[0044] The implementation principle of this embodiment is as follows: As the amount of water vapor increases, the moving tube 12 will move outward. When the vent 15 on the moving tube 12 moves to the outside of the sealing plate 2, the water vapor can enter the moving tube 12 through the through hole 16, and then be discharged into one of the hollow tubes 6 through the vent 15 and the guide cover 10, thereby preventing excessive gas accumulation in the heat exchange cylinder 1 and ensuring that the heat dissipation fins 5 located at the top can also effectively dissipate heat. Moreover, if the guide cover 10 is accidentally removed, the moving tube 12 will continue to move outward due to the pressure of gas or hot water. At this time, the safety plate 21 will be tightly attached to the inner wall of the sealing plate 2, sealing the sliding hole 11 and preventing hot water or hot steam from spraying out and injuring people when the guide cover 10 is accidentally removed. In addition, when the heat exchange cylinder 1 is filled with hot water, the buoyancy of the float plate 19 will drive the limit pin 18 to move upward and insert into the insertion hole 20, preventing the moving tube 12 from moving outward due to water pressure, thereby maintaining the seal of the heat exchange cylinder 1 and preventing hot water from flowing out.

[0045] Example 3:

[0046] refer to Figure 6 A thin tube 23 with one end sealed is connected to the water inlet pipe 3. The thin tube 23 is located inside the heat exchange cylinder 1. Several equally spaced water spray holes 24 are opened on the upper side wall of the thin tube 23, and the diameter of the water spray holes 24 gradually increases along the direction away from the water inlet pipe 3.

[0047] With the above setup, when hot water enters the thin tube 23 from the inlet pipe 3, the pressure of the hot water increases due to factors such as the change in pipe diameter. Subsequently, the hot water will be sprayed upward through the spray hole 24, allowing the hot water to contact the top of the heat exchange cylinder 1. In this way, even if the amount of hot water inside the heat exchange cylinder 1 is small, the heat dissipation fins 5 at the top can fully exert their heat dissipation function. Moreover, the diameter of the spray hole 24 is reasonably designed. This diameter variation can limit the discharge of too much hot water from the spray hole 24 near the inlet pipe 3, preventing the subsequent spray hole 24 from failing to spray hot water to the top inner wall of the heat exchange cylinder 1 due to insufficient pressure. This ensures the uniformity of contact between the hot water and the inner wall of the heat exchange cylinder 1, thereby effectively improving the cooling effect.

[0048] The implementation principle of this embodiment is as follows: by reducing the pipe diameter and increasing the pressure of the hot water, the hot water is sprayed upwards and contacts the upper cylinder wall, thereby utilizing the heat dissipation fins 5 at the upper end to improve the cooling and heat dissipation effect.

[0049] In summary, this device can fully utilize all the heat dissipation fins 5 to cool and dissipate heat when a small amount of hot water passes through, and form an air channel inside the hot water to dissipate heat when a large amount of hot water passes through, resulting in excellent overall heat dissipation performance.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
