Description

Technical Field

[0001] This utility model relates to the technical field of heat exchange devices, specifically an active rotary heat exchange device. Background Technology

[0002] Most existing heat exchange devices use coiled copper tubing in conjunction with a fan to rapidly exchange heat between the refrigerant inside the copper tubing and the external medium. In daily life, the most common example is an air conditioning system. Figure 1 As shown, the working principle of the existing air conditioning system is as follows: The compressor compresses the gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant, which is then sent to the condenser (outdoor unit) to dissipate heat and become a room-temperature, high-pressure liquid refrigerant (so the outdoor unit blows out hot air). It then enters the evaporator (indoor unit) through the expansion valve. Because the space suddenly increases and the pressure decreases after the refrigerant reaches the evaporator from the expansion valve, the liquid refrigerant vaporizes and becomes a low-temperature gaseous refrigerant, thereby absorbing a large amount of heat. The evaporator becomes cold, and at this time, the indoor unit's fan blows indoor air through the evaporator, so the indoor unit blows out cold air. Water vapor in the air condenses into water droplets when it encounters the cold evaporator and flows out along the drain pipe. This is why the air conditioner produces water when cooling in the summer.

[0003] However, in the existing technology, the copper tubes of the evaporator (or condenser) are fixed statically inside the indoor or outdoor unit in a coiled form, and the fan is fixed on one side of the copper tubes, while the other side of the copper tubes does not have sufficient contact with the air, resulting in energy waste. Utility Model Content

[0004] The purpose of this invention is to provide an active rotary heat exchange device to solve the problem in the prior art where the copper tubes of existing heat exchange devices are fixed inside the device in a coiled manner, and the fan is fixed on one side of the copper tubes, while the other side of the copper tubes does not have sufficient contact with the air, resulting in energy waste.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an active rotary heat exchange device, including a support base, universal joints installed at both ends of the top of the support base, and a rotatable main shaft installed between adjacent universal joints via bearings, a plurality of fan blades being provided on the surface of the main shaft, and a copper tube passing through the fan blades being wound around the surface of the main shaft, and the main shaft, fan blades and copper tube being integrally formed, and a drive mechanism being installed on the surface of the support base, the drive mechanism being used to drive the main shaft to rotate.

[0006] Preferably, the drive mechanism includes a drive motor, a main synchronous pulley, a synchronous belt, and a drive mechanism, wherein the drive motor is mounted on the surface of the support base.

[0007] Preferably, the output end of the drive motor is equipped with a main synchronous pulley, and the slave synchronous pulley is mounted on the surface of the main shaft via a spline.

[0008] Preferably, a timing belt is wound between the slave timing pulley and the master timing pulley, and the timing belt is used to drive the slave timing pulley to rotate when the master timing pulley rotates.

[0009] Preferably, one end of the spindle is provided with an air inlet for air intake, and the air inlet is connected to an external air intake copper pipe, and the air inlet is connected to the air intake end of the copper pipe.

[0010] Preferably, the other end of the main shaft is provided with an air outlet for air discharge, and the air outlet is connected to an external air outlet copper pipe, and the air outlet is connected to the air outlet end of the copper pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the overall system remains unchanged, only the arrangement of the copper tubes in the heat exchange device is altered. The copper tubes and fan are integrated into one unit, and a drive motor rotates the main shaft. The copper tubes are wound around the main shaft, allowing the heat exchange device to change from passive to active rotation. The rotation of the main shaft propels the refrigerant inside the copper tubes forward, acting like a water pump, and also agitates the refrigerant, ensuring more thorough contact with the copper tube walls. Furthermore, the fan blades are arranged around the main shaft, ensuring full contact between the air and all sides of the copper tubes, solving the problem in existing technologies where only half of the copper tubes are in full contact with the air. Because the copper tubes are in circular motion, any mist film adhering to the tubes is directly flung out and atomized by the fan blades, providing humidification without the discharge of condensate.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. In addition, the terms "first", "second", "third", "upper", "lower", "left", "right", etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance. At the same time, in the description of the present utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0020] The structure of the active rotary heat exchange device provided by this utility model is as follows: Figure 2 as well as Figure 4 As shown, the device includes a support base 1. Both ends of the top of the support base 1 are equipped with universal joints 11 for connecting external copper pipes. The universal joints 11 are rotatably connected to the external copper pipes. A rotatable main shaft 2 is installed between adjacent universal joints 11 via bearings. One end of the main shaft 2 is provided with an air inlet 22 for air intake and is connected to an external air intake copper pipe and the air inlet end of the copper pipe 4. The other end of the main shaft 2 is provided with an air outlet 21 for air exhaust and is connected to an external air exhaust copper pipe and the air outlet end of the copper pipe 4. The surface of the main shaft 2 is provided with several fan blades 3. A copper pipe 4 passing through the fan blades 3 is wound around the surface of the main shaft 2. The main shaft 2, fan blades 3, and copper pipe 4 are integrally formed.

[0021] During implementation, the intake copper pipe is installed on the universal joint 11 and connected to the intake port 22 of the main shaft 2. The exhaust pipe is then installed on the other end of the universal joint 11 and connected to the exhaust port 21 of the main shaft 2.

[0022] Furthermore, such as Figure 3 as well as Figure 5As shown, a drive mechanism 5 is mounted on the surface of the support base 1. The drive mechanism 5 is used to drive the main shaft 2 to rotate. The drive mechanism 5 includes a drive motor 51, a main synchronous pulley 52, a synchronous belt 53, and the drive mechanism 5. The drive motor 51 is mounted on the surface of the support base 1. The main synchronous pulley 52 is mounted on the output end of the drive motor 51. The slave synchronous pulley 54 is mounted on the surface of the main shaft 2 through a keyway and spline. A synchronous belt 53 is wound between the slave synchronous pulley 54 and the main synchronous pulley 52. ​​The synchronous belt 53 is used to drive the slave synchronous pulley 54 to rotate when the main synchronous pulley 52 rotates.

[0023] During implementation, the drive motor 51 drives the main synchronous pulley 52 to rotate. When the main synchronous pulley 52 rotates, it will drive the secondary synchronous pulley 54 to rotate from the left and right sides of the synchronous belt 53, thereby causing the main shaft 2 to rotate. Since the copper tube 4 is wound on the main shaft 2, the heat exchange device can be changed from passive to active rotation. The rotation of the main shaft 2 can push the refrigerant in the copper tube 4 forward.

[0024] For example, the heat exchange device of this embodiment can be applied to an air conditioning system as the evaporator and condenser. In operation, the air conditioning system's compressor compresses the gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant, which is then sent to the condenser (outdoor unit) to dissipate heat and becomes a room-temperature, high-pressure liquid refrigerant (hence the hot air blown out by the outdoor unit). It then enters the evaporator (indoor unit) through the expansion valve. Because the space suddenly increases and the pressure decreases after the refrigerant reaches the evaporator from the expansion valve, the liquid refrigerant vaporizes, becoming a low-temperature gaseous refrigerant, thus absorbing a large amount of heat. The evaporator then cools down. At this time, the indoor unit's fan blows indoor air through the evaporator, so the indoor unit blows out cold air. In this invention, the overall air conditioning system remains unchanged; only the arrangement of the evaporator copper pipes and condenser copper pipes is changed, that is, the copper pipes and fan are integrated into one unit.

[0025] When in use, the drive motor 51 drives the main shaft 2 to rotate, and the copper tube 4 is wound around the main shaft 2, which can change the evaporator (or condenser) from passive to active rotation. The rotation of the main shaft 2 can push the refrigerant in the copper tube 4 forward, which can act like a water pump. It can also agitate the refrigerant in the copper tube 4, so that it can make more full contact with the wall of the copper tube 4.

[0026] Moreover, the fan blades 3 are also arranged around the main shaft 2, bringing the air into full contact with the copper tube 4, solving the problem that only half of the copper tube 4 is in full contact with the air in the existing technology. Furthermore, since the copper tube 4 is making circular motion, the mist film attached to the copper tube 4 will be directly thrown out and atomized under the blowing action of the fan blades 3, which not only plays a humidifying role, but also prevents condensate from being discharged.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
