Description

Technical Field

[0001] The utility model relates to the technical field of air heat exchange equipment, in particular to an air energy heat exchange device. Background Technique

[0002] A heat exchanger is a device that transfers part of the heat of a high-temperature fluid to a low-temperature fluid, also known as a heat exchanger. Heat exchangers play an important role in many industrial productions such as chemical industry, petroleum, power, food and others. The working principle of an air energy heat exchanger is to absorb the low-temperature medium in the air through an evaporator, vaporize it through a fluorine medium, increase the temperature by pressurization through a compressor, and then heat the water after conversion through the heat exchanger. Since the air energy heat exchanger exchanges heat through a medium, there is no need for a heating element to directly contact the water, avoiding the risk of electric shock in an electric water heater. A prior art air energy heat exchanger disclosed in the patent publication No. CN211651304U includes a water tank body and a heating coil. The heating coil is located outside the water tank body. The heating coil includes a first heating pipe and a second heating pipe. The first heating pipe rotates clockwise along the circumferential direction of the water tank body, and the second heating pipe rotates counterclockwise along the circumferential direction of the water tank body. The first heating pipe and the second heating pipe are arranged in an alternating manner. The bottom of the first heating pipe is connected to a first intake pipe, the top of the first heating pipe is connected to a first outlet pipe, the top of the second heating pipe is connected to a second intake pipe, and the bottom of the second heating pipe is connected to a second outlet pipe. However, the current structure design of the air energy heat exchanger is relatively single. When the air energy heat exchanger is working, its heat conversion effect is not ideal, and the heat of the air cannot be fully transferred to the liquid. During the flow of the liquid, due to the relatively fast speed, the contact time with the heat of the high-temperature air is relatively short. Content of the Utility Model

A plurality of heat exchange tubes 5 are axially and evenly connected to the top of the water distribution tray 3. The heat exchange tubes 5 are in an inverted U shape. The bottom output end of the heat exchange tubes 5 is connected with a liquid collection tray 6. The liquid collection tray 6 is located above the water distribution tray 3. The output end of the liquid collection tray 6 is connected with a liquid outlet pipe 7. The liquid outlet pipe 7 passes through the right side wall of the cylinder body 1 and extends to the outside. The air inlet pipe 8 is installed on the lower side wall of the cylinder body 1. The input end of the air inlet pipe 8 is located inside the cylinder body 1 and is connected with an annular pipe 9. A plurality of gas transmission pipes 10 are evenly connected to the annular pipe 9. A plurality of air outlet holes are opened on the gas transmission pipes 10. The air outlet pipe 13 is fixedly connected to the air outlet hole at the top of the cylinder body 1. A plurality of support rods 14 are axially and evenly installed at the top end inside the cylinder body 1 with respect to the air outlet hole. A bearing 15 is installed in the middle of the plurality of support rods 14. A rotating shaft 16 is rotatably installed in the middle of the bearing 15. A turbine 17 is installed on the upper part of the rotating shaft 16. The turbine 17 is located inside the air outlet pipe 13. A plurality of rotating rods 18 are connected to the lower part of the rotating shaft 16. A push plate 19 is installed at the bottom of the rotating rods 18;

[0021] The liquid is input into the water distribution tray 3 through the liquid inlet pipe 2, and then respectively input into a plurality of heat exchange tubes 5. The U-shaped heat exchange tubes 5 can increase the residence time of the liquid inside the cylinder body 1, increase the heat exchange time, enable the liquid to fully contact and exchange heat with the high-temperature gas. Then the liquid is input into the liquid collection tray 6 for collection and discharged through the liquid outlet pipe 7. The high-temperature gas is input into the annular pipe 9 from the gas inlet pipe 8, and evenly distributed and flows into the gas transmission pipe 10 through the annular pipe 9, so that the high-temperature gas is evenly ejected from the air outlet holes of the gas transmission pipe 10, sprayed towards the heat exchange tubes 5 to exchange heat with the liquid. After the heat exchange is completed, the gas moves upward. When discharging towards the air outlet pipe 13 through the air outlet holes, it drives the turbine 17 to rotate.

The rotating shaft 16 drives the pushing plate 19 to rotate through the rotating rod 18, pushes and mixes the lower high-temperature gas, enables the high-temperature gas to be evenly distributed, ensures the temperature uniformity, and improves the heat exchange effect.

[0022] Embodiment 2

A plurality of support legs 24 are axially and evenly installed on the support ring 23, and the bottom of the support legs 24 is fixedly installed with a bottom plate 25;

[0024] When the liquid flows in the heat exchange tubes 5, the baffles 11 block the liquid, and the liquid velocity is reduced through the water permeable holes, enabling the liquid to fully contact the high-temperature gas. At the same time, the fin plates 12 increase the contact area between the outer wall of the heat exchange tubes 5 and the high-temperature gas, improving the heat conversion effect. When the gas moves upward, it is blocked by the retaining rings 20, and the gas flows upward through the air permeable holes, slowing down the gas velocity, increasing the contact time, improving the heat exchange effect, and maximizing the utilization of the gas temperature. The cylinder body 1 is supported by the support legs 24 and the bottom plate 25, and the rear part of the cylinder body 1 can be fixed through the two fixing seats 21 and the fixing plates 22, facilitating the selection of different fixing methods according to different use environments and improving the practicability.

[0025] As Figures 1 to 5As shown, in a working process of an air energy heat exchange device of the present utility model, a liquid is input into a water distribution tray 3 through a liquid inlet pipe 2, and then respectively input into a plurality of heat exchange tubes 5. The U-shaped heat exchange tubes 5 can increase the residence time of the liquid inside a cylinder body 1. High-temperature gas is input into an annular tube 9 from an air inlet pipe 8, and uniformly distributed and flows into a gas transmission pipe 10 through the annular tube 9, so that the high-temperature gas is uniformly ejected from air outlet holes of the gas transmission pipe 10 and sprayed towards the heat exchange tubes 5 to exchange heat with the liquid. When the liquid flows inside the heat exchange tubes 5, a baffle 11 is used to block the liquid, and the liquid flow rate is reduced through water permeable holes, so that the liquid and the high-temperature gas are in full contact. Meanwhile, fin plates 12 increase the contact area between the outer wall of the heat exchange tubes 5 and the high-temperature gas, so that the liquid and the high-temperature gas are in full contact for heat exchange. Then the liquid is input into a liquid collecting tray 6 for collection and discharged through a liquid outlet pipe 7. After heat exchange, the gas moves upward. When the gas is discharged towards an air outlet pipe 13 through an air outlet hole, a turbine 17 is driven to rotate. The turbine 17 drives a rotating shaft 16 to rotate, and the rotating shaft 16 drives a pushing plate 19 to rotate through a rotating rod 18 to push and mix the lower high-temperature gas, so that the high-temperature gas is uniformly distributed to ensure temperature uniformity. When the gas moves upward, it is blocked by a retaining ring 20, and the gas flows upward through air permeable holes, so that the gas flow rate is slowed down, the contact time is increased, and the temperature of the gas is utilized to the maximum extent.
