Description

Technical Field

[0001] This utility model relates to the field of heat exchanger structure, and in particular to a high-efficiency heat exchanger structure for dehumidifiers. Background Technology

[0002] The heat exchanger in a dehumidifier is the core functional component that enables air cooling and dehumidification. It works by exchanging heat between the air and the refrigerant, causing water vapor in the air to condense and separate, thereby reducing air humidity. As the "heart" of the dehumidifier, its heat exchange efficiency, operational stability, and structural rationality directly determine the dehumidifier's dehumidification capacity, energy consumption level, and service life. It is widely used in household, commercial, and industrial dehumidification scenarios.

[0003] Currently, most heat exchangers have parallel and uniformly distributed fins, resulting in limited contact area with air. Furthermore, the assembly gap between the copper tubes and fins is relatively large, leading to increased heat loss during heat transfer and low heat exchange efficiency. In addition, there is no dedicated flow guiding and drainage structure inside the chamber, causing condensate to accumulate at the bottom. This not only hinders air circulation but may also cause corrosion of the fins and copper tubes due to long-term water accumulation, affecting the lifespan of the equipment. To address this technical problem, this application proposes a high-efficiency heat exchanger structure for dehumidifiers. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency heat exchanger structure for dehumidifiers. Through staggered fins and tightly fitted copper tubes, the air contact area is increased and heat loss is reduced, significantly improving heat exchange efficiency. The drainage structure composed of a funnel and a drain pipe can quickly discharge condensate, preventing water accumulation and corrosion of components. At the same time, the fan blades accelerate air circulation, optimizing the overall dehumidification performance and service life of the equipment.

[0006] Furthermore, a mounting plate is fixedly connected to the center of the right side of the housing. Mounting holes are provided at the four corners of the mounting plate. Bolts are threaded to the right side of the mounting holes. A protective cover is fixedly connected to the right side of the mounting plate. A ventilation opening is provided on the right side of the protective cover. A rotating rod is rotatably connected to the left side of the ventilation opening. Six fan blades are fixedly connected to the outer wall of the rotating rod.

[0007] Furthermore, side plates are fixedly connected to the left and right sides of the connecting plate, and baffles are fixedly connected to the upper and lower sides of the connecting plate.

[0008] Furthermore, fins are fixedly connected to the inner wall of the box, and the fins are distributed alternately inside the box.

[0009] Furthermore, the fins have holes, and the diameter of the copper tube is the same as the diameter of the inner wall of the hole.

[0010] Furthermore, a connecting block is fixedly connected to the lower side of the side plate away from the connecting plate, and a support plate is fixedly connected to the right side of the connecting block.

[0011] Furthermore, a base plate is fixedly connected to the bottom of the support plate, and a positioning hole is provided on the side of the base plate away from the support plate.

A connecting pipe 9 is fixedly connected to the upper right side of the housing 1, and a base plate 20 is fixedly connected to the right end of the connecting pipe 9. An air outlet 2 is fixedly connected to the lower left side of the housing 1, and the base plate 20 is fixedly connected to the left side of the air outlet 2. A funnel 3 is fixedly connected to the bottom of the housing 1. The funnel 3 at the bottom of the housing 1 can collect the condensate water condensed on the inner wall of the housing 1 and the fins 14, and then quickly discharge it outside the equipment through the drain pipe 21 at the bottom, preventing the accumulation of condensate water from corroding internal components or affecting the heat exchange effect. Connecting plates 10 are fixedly connected to the front and rear sides of the housing 1. Several copper pipes 4 are fixedly connected to the side of the connecting plates 10 away from the housing 1. The copper pipes 4 are stably fixed by the connecting plates 10. Refrigerant flows inside the copper pipes 4 and can exchange heat with the outside air.

[0019] Reference Figure 2-5A mounting plate 5 is fixedly connected to the center of the right side of the housing 1. Mounting holes 11 are provided at the four corners of the mounting plate 5. Bolts 6 are threaded to the right side of the mounting holes 11. A protective cover 8 is fixedly connected to the right side of the mounting plate 5. A ventilation opening 7 is provided on the right side of the protective cover 8. A rotating rod 13 is rotatably connected to the left side of the ventilation opening 7. Six fan blades 12 are fixedly connected to the outer wall of the rotating rod 13. Side plates 19 are fixedly connected to the left and right sides of the connecting plate 10. Baffles 18 are fixedly connected to the top and bottom sides of the connecting plate 10. The side plates 19 and baffles 18 together form a protective structure to prevent the copper pipe 4 from being damaged by external impact. The inner wall of the housing 1... Fins 14 are fixedly connected and are staggered inside the housing 1. The staggered fins 14 increase the contact area and improve the working efficiency of the heat exchanger. Holes are opened on the fins 14. The diameter of the copper tube 4 is the same as the inner wall diameter of the hole. A connecting block 17 is fixedly connected to the lower side of the side plate 19 away from the connecting plate 10. A support plate 16 is fixedly connected to the right side of the connecting block 17. A bottom plate 20 is fixedly connected to the bottom of the support plate 16. A positioning hole 15 is opened on the side of the bottom plate 20 away from the support plate 16. A drain pipe 21 is provided at the bottom of the funnel 3. A sealing ring is provided at the connection between the funnel 3 and the housing 1.

[0020] Working Principle: During the equipment installation phase, the heat exchanger is first aligned with the preset installation position inside the dehumidifier using the positioning holes 15 on the base plate 20. The positioning holes 15 guide the connection between the equipment and the internal air ducts and pipes of the dehumidifier, preventing airflow obstruction or pipe connection problems due to positional misalignment during subsequent operation. Then, bolts 6 are passed through the mounting holes 11 at the four corners of the mounting plate 5 to firmly fix the protective cover 8 to the mounting plate 5. The bolts 6 are equipped with buffer pads to prevent the protective cover 8 from loosening due to vibrations generated during equipment operation. The protective cover 8 protects internal rotating parts such as the fan blades 12 from external impact damage. After the equipment starts, the rotating rod 13 drives the fan blades 12 to rotate synchronously. The rotation of the fan blades 12 generates directional airflow, forming a stable wind pressure, guiding clean external air into the housing 1 at a uniform speed through the vent 7 on the right side of the protective cover 8, providing an air source for subsequent heat exchange. Meanwhile, the humid and hot air to be treated inside the dehumidifier flows smoothly into the housing 1 through the connecting pipe 9 on the upper right side of the housing 1 under the action of the internal air pressure difference. The two airflows flow along the preset path inside the housing 1, forming orderly convection and avoiding heat exchange dead zones caused by airflow turbulence. At this time, the staggered structure of the fins 14 distributed on the inner wall of the housing 1 increases the contact area with the air, allowing the humid and hot air to come into more full contact with the surface of the fins 14. The copper tube 4 is perfectly matched with the holes on the fins 14, and the two fit tightly without gaps. This design reduces the loss in the heat transfer process. The refrigerant flowing inside the copper tube 4 continuously absorbs the heat transferred by the fins 14, thereby reducing the temperature of the humid and hot air. As the temperature drops, the water vapor in the humid and hot air quickly condenses into tiny water droplets. These water droplets adhere to the fins 14 and the inner wall of the housing 1, and gradually gather into larger water droplets under the action of gravity. They slowly slide down the surface of the fins 14 and the inner wall of the housing 1, and finally drip into the funnel 3 at the bottom of the housing 1. The sealing ring at the connection between the funnel 3 and the housing 1 tightly seals the gaps, completely blocking the leakage path of condensate water and preventing it from seeping into other areas of the equipment. This avoids corrosion of the fins 14 and copper pipes 4 due to water accumulation, and also prevents water accumulation from obstructing airflow within the housing 1. The condensate water collected in the funnel 3 is quickly discharged to the outside of the equipment through the drain pipe 21 at the bottom, without affecting the subsequent heat exchange process. The dry air after heat exchange is continuously propelled by the airflow generated by the fan blades 12 and smoothly discharged from the air outlet 2 on the lower left side of the housing 1, smoothly entering the subsequent air duct of the dehumidifier and finally being delivered to the target space requiring dehumidification. During this process, the side plates 19 on both sides of the connecting plate 10 and the baffles 18 on the upper and lower sides always surround the outside of the copper pipes 4, resisting minor vibrations or minor external collisions that may occur during equipment operation, preventing refrigerant leakage due to external damage to the copper pipes 4, ensuring stable refrigerant flow, and thus ensuring continuous and efficient heat exchange throughout the entire process, extending the service life of the equipment.

[0021] It is worth noting that the protection and sealing involved in the above embodiments are all based on the corresponding existing technologies according to the actual situation, and therefore will not be described in detail in the embodiments of this application.
