Description

Technical Field

[0001] This utility model relates to the field of air conditioning heat exchange technology, specifically to an evaporation and condensation mechanism. Background Technology

[0002] In modern industrial production, refrigeration systems, and many other fields requiring heat exchange, evaporation-condensation mechanisms play a crucial role as key equipment for achieving efficient heat conversion and transfer. Their core function is to transfer heat from one area to another through the processes of evaporation and condensation, thereby meeting diverse process requirements and environmental constraints.

[0003] For example, Chinese patent document CN210035709U discloses an integrated air conditioner, which includes a housing. Inside the housing, from top to bottom, are arranged an evaporator, an upper water tray, a spray pipe, and a condenser. The evaporator is connected to the condenser. One end of the spray pipe is connected to the upper water tray, and the other end extends to the condenser. Condensate collected in the upper water tray flows downwards through the spray pipe and drips onto the condenser, thus cooling the condenser. However, this structural design is relatively complex, requiring the upper water tray to receive condensate and the spray pipe to cool the condenser. This complex structure not only increases the manufacturing cost and installation difficulty of the equipment but also makes it prone to malfunctions and leaks during long-term operation, significantly reducing the reliability and stability of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide an evaporation and condensation mechanism that has a simple structure and high heat exchange efficiency.

[0005] The technical solution adopted by the evaporation and condensation mechanism disclosed in this utility model is:

[0006] An evaporation-condensation mechanism includes several vertically parallel heat exchange fins, evaporation straight tubes, and condensation straight tubes. The heat exchange fins, evaporation straight tubes, and condensation straight tubes form an evaporation zone, a transition zone, and a condensation zone. The evaporation zone is located at the top, the condensation zone is located at the bottom, and the transition zone is located between the evaporation zone and the condensation zone. The portion of the heat exchange fins located in the evaporation zone has several evaporation tube holes, and the portion of the heat exchange fins located in the condensation zone has several condensation tube holes. The evaporation straight tubes pass through the evaporation tube holes of the heat exchange fins, and the condensation straight tubes pass through the condensation tube holes of the heat exchange fins.

[0007] As a preferred embodiment, several vertically arranged evaporation tubes are staggered laterally, and at least one condensation tube in the condensation zone is located directly below the evaporation tube.

[0008] As a preferred embodiment, the spacing between the heat exchange fins is 1mm-5mm.

[0009] As a preferred embodiment, the heat exchange fins are provided with a transition section, and the evaporator tube holes and condenser tube holes are respectively located at both ends of the transition section.

[0010] As a preferred embodiment, the height of the transition zone is 5cm-15cm, and the height of the transition portion corresponds to the height of the transition zone.

[0011] Its characteristic is that the windward surfaces of the evaporation zone and the condensation zone are both located on the same vertical plane.

[0012] As a preferred embodiment, the system also includes a mounting bracket, which includes mounting side plates spaced apart on the left and right sides. The mounting side plates are provided with mounting holes, and the two ends of the evaporator straight tube and the condenser straight tube pass through the mounting holes of the mounting side plates to form a fixed structure.

[0013] As a preferred embodiment, an evaporation U-shaped tube is connected to the end of adjacent evaporation straight tubes, and a condensation U-shaped tube is connected to the end of adjacent condensation straight tubes.

[0014] As a preferred embodiment, the mounting side plate is provided with a baffle, the length of which extends to both ends of the baffle is greater than the length of which both ends of the evaporator straight tube and the condenser straight tube extend.

[0015] The beneficial effects of the evaporation and condensation mechanism disclosed in this utility model are as follows: the condensate generated by the heat exchange between the evaporation straight tube in the evaporation zone and the air flows along the side of the heat exchange plates to the condensation straight tube in the condensation zone under the action of gravity. Some of the condensate drips directly onto the condensation straight tube under the action of gravity, thus cooling the condensation straight tube in the condensation zone. The condensate evaporates and absorbs heat on the condensation straight tube, further reducing the temperature of the condensation straight tube and improving the heat exchange efficiency of the condensation zone. Moreover, the condensate that falls into the condensation zone will not cause air pollution when it evaporates into the air, and can also maintain the humidity of the air, which is conducive to the recycling of moisture in the air.

[0021] An evaporation-condensation mechanism includes several vertically parallel heat exchange fins, evaporation straight tubes, and condensation straight tubes. The heat exchange fins, evaporation straight tubes, and condensation straight tubes form an evaporation zone, a transition zone, and a condensation zone. The evaporation zone is located at the top, the condensation zone is located at the bottom, and the transition zone is located between the evaporation zone and the condensation zone. The portion of the heat exchange fins located in the evaporation zone has several evaporation tube holes, and the portion of the heat exchange fins located in the condensation zone has several condensation tube holes. The evaporation straight tubes pass through the evaporation tube holes of the heat exchange fins, and the condensation straight tubes pass through the condensation tube holes of the heat exchange fins.

[0022] The condensate produced by heat exchange between the evaporator tubes in the evaporation zone and the air flows along the side of the heat exchange plates under the influence of gravity onto the condenser tubes in the condensation zone. Some of the condensate drips directly onto the condenser tubes under the influence of gravity, thus cooling the condenser tubes. The condensate evaporates and absorbs heat on the condenser tubes, further reducing their temperature and improving the heat exchange efficiency of the condensation zone. Moreover, the condensate that falls into the condensation zone evaporates into the air without causing air pollution and can maintain air humidity, which is beneficial for the recycling of moisture in the air.

[0023] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0024] Please refer to Figures 1 to 5 An evaporation and condensation mechanism includes several vertically parallel heat exchange fins 10, an evaporation straight tube 20, and a condensation straight tube 30, wherein the evaporation straight tube 20 and the heat exchange fins 10 are arranged perpendicularly.

[0025] The vertically arranged evaporator tubes 20 are arranged in a horizontally staggered manner, so that there is a certain horizontal distance between adjacent upper and lower evaporator tubes 20. This avoids water droplets generated by the upper evaporator tube 20 from directly colliding with the lower evaporator tube 20. The condenser tubes 30 are arranged horizontally staggered from top to bottom to correspond to the evaporator tubes 20. This allows water droplets generated by each evaporator tube 20 to fall directly onto the corresponding condenser tube 30 below under the action of gravity. This effectively prevents water droplets generated by the evaporator tubes 20 from only acting on the uppermost condenser tube 30, thereby improving the condensation efficiency and heat exchange performance of the entire evaporation and condensation mechanism.

[0026] The heat exchange fins 10 are parallel to each other and are all perpendicular to the horizontal plane. The distance between adjacent heat exchange fins 10 is 1mm-5mm.

[0027] The compact spacing between the heat exchange fins 10 significantly increases the heat exchange area and improves heat exchange efficiency. The smaller spacing helps reduce thermal resistance, allowing heat to be transferred more efficiently between the heat exchange fins 10, thereby enhancing the performance of the entire evaporation-condensation mechanism. Simultaneously, it also makes the entire mechanism more space-saving, facilitating installation and use.

[0028] The heat exchange plate 10, the evaporation straight tube 20, and the condensation straight tube 30 form an evaporation zone 40, a transition zone 60, and a condensation zone 50. The evaporation zone 40 is located at the top, the condensation zone 50 is located at the bottom, and the transition zone 60 is located between the evaporation zone 40 and the condensation zone 50. The transition zone 60 allows the evaporation zone 40 and the condensation zone 50 to operate independently without affecting each other.

[0029] In the evaporation zone 40, the evaporation straight tube 20 exchanges heat with the air, producing condensate. This condensate flows along the side of the heat exchange fins 10 through the transition zone 60 or drips directly under the action of gravity, eventually reaching the condensation zone 50.

[0030] In the condensation zone 50, the condensing straight tube 30 utilizes the condensate generated in the evaporation zone 40, taking advantage of its low-temperature characteristics for cooling and the heat absorption properties of condensate evaporation, further improving condensation efficiency. This not only improves the heat exchange efficiency of the condensation zone 50 but also fully utilizes the low-temperature characteristics of the condensate, eliminating the need for additional cooling equipment or energy consumption, achieving energy recycling, and improving energy utilization efficiency.

[0031] The heat exchange fins 10 are provided with multiple evaporation tube holes 11 and condensation tube holes 12 arranged along their length. The evaporation tube holes 11 and condensation tube holes 12 can be arranged alternately or in separate areas on the heat exchange fins 10 to optimize liquid flow and heat exchange efficiency. The evaporation straight tube 20 passes through the evaporation tube holes 11 of the heat exchange fins 10, and the condensation straight tube 30 passes through the condensation tube holes 12 of the heat exchange fins 10. The diameter of each evaporation tube hole 11 and the second liquid hole can be designed according to actual needs, ranging from 1cm to 3cm, to ensure smooth flow of the refrigerant in the evaporation straight tube 20 and the condensation straight tube 30.

[0032] The heat exchange fins 10 are also provided with a transition section 13, and the evaporation tube hole 11 and the condensation tube hole 12 are respectively provided at both ends of the transition section 13.

[0033] The height of the transition zone 60 is 5cm-15cm, corresponding to the height of the transition section 13 on the heat exchange fins 10. The transition zone 60 sets the evaporation zone 40 and the condensation zone 50 alternately, which can significantly improve the heat exchange efficiency and the overall performance of the mechanism. The height of the transition zone 60 can be flexibly adjusted according to the size and power requirements of the specific mechanism to achieve the best heat exchange effect.

[0034] The evaporation zone 40 and the condensation zone 50 are both located on the same vertical plane, that is, they are located on the same plane perpendicular to the airflow direction. This ensures that the airflow can flow evenly through the entire evaporation and condensation mechanism, maximizing the heat exchange efficiency of each area. Furthermore, because the airflow can act on both the evaporation zone 40 and the condensation zone 50 simultaneously, the heat transfer is more uniform.

[0035] The evaporation-condensation mechanism further includes a mounting bracket 70, which includes a mounting side plate 71, a top plate, and a bottom plate spaced apart on the left and right. The mounting side plate 71 is provided with mounting holes 711. The two ends of the evaporation straight tube 20 and the condensation straight tube 30 pass through the mounting holes 711 of the mounting side plate 71 to form a fixation. The top plate is positioned above a plurality of heat exchange fins, and the bottom plate is positioned below a plurality of heat exchange fins. The top plate and the bottom plate not only provide additional support for the heat exchange fins, but also play a certain protective role, effectively extending the service life of the evaporation-condensation mechanism.

[0036] The evaporator straight tube 20 and the condenser straight tube 30 can be fixed to both sides of the mounting side plate 71 through the mounting holes 711 by a fixing device. The fixing device can be used by nuts, snap rings or welding to ensure the stability and reliability of the evaporator straight tube 20 and the condenser straight tube 30 during operation, while facilitating installation and maintenance. More preferably, the mounting side plate 71 can be made of metal material, such as aluminum alloy or stainless steel, which has sufficient strength and corrosion resistance to extend the service life of the mechanism.

[0037] An evaporation U-shaped tube 21 is connected to the end of each adjacent evaporation straight tube 20, and a condensation U-shaped tube 31 is connected to the end of each adjacent condensation straight tube 30.

[0038] In this embodiment, both the evaporator U-tube 21 and the condenser U-tube 31 are made of corrosion-resistant materials, such as stainless steel or copper alloy, to ensure long-term stable operation. The evaporator U-tube 21 and the condenser U-tube 31 increase the flow path of the refrigerant, allowing the refrigerant to be distributed more evenly between the evaporation zone 40 and the condensation zone 50, thereby improving heat exchange efficiency. Furthermore, the two ends of the evaporator U-tube 21 and the condenser U-tube 31 can be fixed to the evaporator straight tube 20 and the condenser straight tube 30 by welding or threaded connection, ensuring a firm and airtight connection.

[0039] The mounting side plate 71 is provided with a baffle 712. The length of the baffle 712 extending to both ends is greater than the length of the evaporator straight tube 20 and the condenser straight tube 30 extending to both ends. The baffle 712 can play a certain protective role, preventing external objects from damaging the evaporator straight tube 20 and the condenser straight tube 30, while improving the overall aesthetics of the mechanism.

[0040] The evaporation and condensation mechanism further includes a compressor, a liquid receiver, an expansion valve, and a centrifugal fan. The compressor provides power to transport the refrigerant from the low-pressure zone to the high-pressure zone, while simultaneously increasing the temperature and pressure of the refrigerant. The liquid receiver can regulate the refrigerant flow rate to ensure stable operation of the system under different operating conditions. The expansion valve can throttle and reduce the pressure of the low-temperature, high-pressure liquid refrigerant, transforming it into a low-temperature, low-pressure liquid refrigerant. The centrifugal fan enhances airflow and improves heat exchange efficiency.

[0041] In this application, the evaporation and condensation mechanism further includes a housing with two centrifugal fans. One centrifugal fan is located in the evaporation zone 40 and works in conjunction with the evaporation straight pipe 20, while the other centrifugal fan is located in the condensation zone 50 and works in conjunction with the condensation straight pipe 30. The centrifugal fans can act on the airflow in the evaporation zone 40 or the condensation zone 50 respectively, promoting airflow through forced convection, ensuring rapid condensate generation and effective cooling of the condensation straight pipe 30, and effectively improving the heat exchange efficiency of the mechanism.

[0042] The shell is equipped with a heat insulation board and sound-absorbing cotton inside, which isolates the evaporation zone 40 from the condensation zone 50 to prevent heat from being directly transferred between the two zones and affecting the heat exchange efficiency; the sound-absorbing cotton can absorb the noise generated by the equipment.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
