Description

Technical Field

[0001] This utility model relates to the technical field of dehumidification equipment, specifically to a U-shaped heat pipe dehumidification heat recovery device. Background Technology

[0002] High humidity environments often cause numerous problems in industrial production, warehousing and logistics, underground buildings, and many other locations with specific humidity requirements. For example, in electronics manufacturing workshops, high humidity can cause electronic components to become damp and short-circuit, affecting product quality and production efficiency; in food warehouses, excessive humidity can accelerate food mold and spoilage, resulting in economic losses; and in underground parking lots and similar locations, high humidity can not only cause discomfort but also potentially damage the building structure. Therefore, effective dehumidification measures are crucial in these environments.

[0003] Currently, traditional dehumidification methods mainly include refrigeration dehumidification and rotary dehumidification. Refrigeration dehumidification uses a refrigeration system to cool the air below its dew point temperature, causing water vapor in the air to condense into liquid water and be discharged, thus achieving dehumidification. However, refrigeration dehumidification consumes a large amount of electricity to drive the compressor and other refrigeration equipment, resulting in high energy consumption. Moreover, the temperature of the dehumidified air drops significantly, and to meet indoor temperature requirements, it is usually necessary to reheat the air using electricity, further increasing energy consumption and wasting resources.

[0004] Rotary dehumidifiers work by adsorbing water vapor from the air with an adsorbent and then regenerating the adsorbent through heating to achieve continuous dehumidification. While rotary dehumidifiers have certain advantages in low-humidity environments, their complex structure, high operating costs, and the significant energy consumption required for regeneration also contribute to their high energy consumption. Utility Model Content

[0005] This invention provides a U-shaped heat pipe dehumidification and heat recovery device, which can solve the problems of high energy consumption and low air temperature after dehumidification in high humidity environments, which require reheating with electricity and waste resources.

[0006] A U-shaped heat pipe dehumidification and heat recovery device includes a base, an evaporation mechanism, a condensation mechanism, and a refrigeration dehumidification mechanism. The evaporation mechanism includes a first support and heat-absorbing copper pipes. The first support is fixedly connected to the base, and the heat-absorbing copper pipes are fixedly connected to the first support. Several heat-absorbing copper pipes are arranged in multiple staggered rows in an inclined state. The condensation mechanism includes a second support and heat-dissipating copper pipes. The second support is fixedly connected to the base, and the heat-dissipating copper pipes are fixedly connected to the second support. Several heat-dissipating copper pipes are arranged in multiple staggered rows in an inclined state. The heat-absorbing copper pipes and heat-dissipating copper pipes are connected to form a closed loop, and both the heat-absorbing and heat-dissipating copper pipes are filled with an environmentally friendly phase change working fluid. The refrigeration dehumidification mechanism is fixedly connected to the base and located between the heat-absorbing and heat-dissipating copper pipes. The environmentally friendly phase change working fluid includes water, and both the heat-absorbing and heat-dissipating copper pipes are filled with water.

[0007] According to one embodiment of this utility model, the refrigeration dehumidification mechanism includes a refrigeration dehumidification component, which is fixedly connected to a base. The refrigeration dehumidification component has an air inlet side and an air outlet side. The evaporation mechanism is located on the air inlet side of the refrigeration dehumidification mechanism, and the condensation mechanism is located on the air outlet side of the refrigeration dehumidification mechanism. The refrigeration dehumidification component is a surface cooler, an evaporator, or other refrigeration device. When the refrigeration dehumidification component is a surface cooler, the surface cooler is fixedly connected to the base and located between the evaporation mechanism and the condensation mechanism; when the refrigeration dehumidification component is an evaporator, the evaporator is fixedly connected to the base and located between the evaporation mechanism and the condensation mechanism.

[0008] According to one embodiment of the present invention, the evaporation mechanism further includes heat-absorbing aluminum fins, a plurality of which are arranged in a rectangular array on the side of the heat-absorbing copper tube, the inclination angle of the heat-absorbing copper tube being 10–25°. The spacing between adjacent heat-absorbing aluminum fins is 1.8–2.3 mm, and the surface of the heat-absorbing aluminum fins is hydrophilic.

[0009] According to one embodiment of the present invention, the condensation mechanism further includes heat dissipation aluminum fins, which are arranged in a rectangular array on the side of the heat dissipation copper tube. The inclination angle of the heat dissipation copper tube is 10-25°. The spacing between adjacent heat dissipation aluminum fins is 1.3-1.8 mm, and the surface of the heat dissipation aluminum fins is treated with a hydrophobic coating.

[0010] According to one embodiment of the present invention, the top of the base is provided with a V-shaped water guide groove, the evaporation mechanism, the condensation mechanism and the refrigeration dehumidification mechanism are all arranged in the water guide groove, and the bottom of the base is provided with a drain hole that communicates with the water guide groove.

[0011] The advantages of this utility model compared to the prior art are:

During dehumidification, no additional power is required to drive heat transfer, reducing energy consumption. Simultaneously, it avoids the need for reheating the air after traditional dehumidification, significantly improving energy efficiency. Furthermore, the multiple rows of staggered, inclined heat-absorbing and heat-dissipating copper pipes increase the contact area with the air, enhancing heat exchange efficiency.

Detailed Implementation

[0021] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0022] First Embodiment

[0023] Please see Figures 1 to 4As shown, a U-shaped heat pipe dehumidification and heat recovery device includes a base 1, an evaporation mechanism 2, a condensation mechanism 3, and a refrigeration dehumidification mechanism 4. The evaporation mechanism 2 includes a first support 5 and heat-absorbing copper pipes 6. The first support 5 is fixedly connected to the base 1, and the heat-absorbing copper pipes 6 are fixedly connected to the first support 5. Several heat-absorbing copper pipes 6 are arranged in an inclined, staggered pattern. The condensation mechanism 3 includes a second support 7 and heat-dissipating copper pipes 8. The second support 7 is fixedly connected to the base 1, and the heat-dissipating copper pipes 8 are fixedly connected to the second support 7. Several heat-dissipating copper pipes 8 are arranged in an inclined, staggered pattern. The heat-absorbing copper pipes 6 and 8 are connected to form a closed loop, and both heat-absorbing and heat-dissipating copper pipes 6 and 8 are filled with an environmentally friendly phase change working fluid. The refrigeration dehumidification mechanism 4 is fixedly connected to the base 1 and located between the heat-absorbing and heat-dissipating copper pipes 6 and 8. The environmentally friendly phase change working fluid includes water, and both heat-absorbing and heat-dissipating copper pipes 6 and 8 are filled with water.

[0024] The high-temperature and high-humidity air first flows through the evaporation mechanism 2 and comes into contact with the heat-absorbing copper tube 6 in the evaporation mechanism 2. This causes the working fluid in the heat-absorbing copper tube 6 to absorb heat and its temperature to rise. When the temperature reaches the boiling point of the liquid working fluid, the liquid working fluid begins to vaporize and evaporate, absorbing a large amount of latent heat (latent heat of vaporization), thereby carrying the heat away from the air. The vaporized gaseous working fluid moves along the upwardly inclined heat-absorbing copper tube 6 into the heat-dissipating copper tube 8.

[0025] The air pre-cooled by the evaporation unit 2 enters the refrigeration dehumidification unit 4 for deep dehumidification. The resulting low-temperature dry air serves as a cold source and flows through the condensation unit 3, coming into contact with the heat dissipation copper pipe 8. At this time, the working fluid in the heat dissipation copper pipe 8 is the gaseous working fluid that evaporates after the heat absorption copper pipe 6 absorbs heat. It releases latent heat in the low-temperature environment, re-condenses into a liquid working fluid, and moves along the downward-sloping heat dissipation copper pipe 8 towards the heat absorption copper pipe 6, thus achieving non-powered heat recovery.

[0026] Heat transfer and recovery are achieved through heat-absorbing copper pipes 6 and heat-dissipating copper pipes 8. During dehumidification, no additional power is required to drive heat transfer, reducing energy consumption. Simultaneously, it avoids the need for reheating the air after traditional dehumidification, significantly improving energy efficiency. Furthermore, the multiple rows of staggered and inclined heat-absorbing copper pipes 6 and 8 increase the contact area with the air, enhancing heat exchange efficiency.

[0027] Second Embodiment

[0028] Based on the first embodiment, the refrigeration dehumidification mechanism 4 includes a refrigeration dehumidification component 9, which is fixedly connected to the base 1. The refrigeration dehumidification component 9 is provided with an air inlet side and an air outlet side. The evaporation mechanism 2 is located on the air inlet side of the refrigeration dehumidification mechanism 4, and the condensation mechanism 3 is located on the air outlet side of the refrigeration dehumidification mechanism 4. The refrigeration dehumidification component 9 is a surface cooler, an evaporator, or other refrigeration device. When the refrigeration dehumidification component 9 is a surface cooler, the surface cooler is fixedly connected to the base 1 and located between the evaporation mechanism 2 and the condensation mechanism 3; when the refrigeration dehumidification component 9 is an evaporator, the evaporator is fixedly connected to the base 1 and located between the evaporation mechanism 2 and the condensation mechanism 3.

[0029] High-temperature, high-humidity air first passes through the evaporator 2 located on the air inlet side of the refrigeration dehumidification unit 4, where it comes into contact with the heat-absorbing copper tube 6. The water working fluid absorbs heat and vaporizes, carrying away the heat from the air. The pre-cooled air then enters the refrigeration dehumidification assembly 9 for deep dehumidification, forming low-temperature, dry air. This low-temperature, dry air, acting as a cold source, flows through the condenser 3 located on the air outlet side of the refrigeration dehumidification unit 4, where it comes into contact with the heat dissipation copper tube 8. The water vapor in the heat dissipation copper tube 8 releases latent heat and condenses into liquid water, flowing back to the heat-absorbing copper tube 6, completing the heat recovery and dehumidification process. The refrigeration dehumidification assembly can be equipped with different refrigeration devices such as surface coolers and evaporators according to actual needs, enhancing the applicability and flexibility of the device. This better meets the dehumidification and heat recovery requirements of different locations and improves the device's operating performance in various environments.

[0030] Third Embodiment

[0031] Based on the first embodiment, the evaporation mechanism 2 further includes heat-absorbing aluminum fins 10. Several heat-absorbing aluminum fins 10 are arranged in a rectangular array on the side of the heat-absorbing copper tube 6, and the inclination angle of the heat-absorbing copper tube 6 is 10–25°. The spacing between adjacent heat-absorbing aluminum fins 10 is 1.8–2.3 mm, and the surface of the heat-absorbing aluminum fins 10 is hydrophilic.

[0032] When high-temperature, high-humidity air flows through the evaporation unit 2, it comes into contact not only with the heat-absorbing copper tube 6 but also with the heat-absorbing aluminum fins 10 arranged in a rectangular array on the side of the heat-absorbing copper tube 6. The heat-absorbing aluminum fins 10 increase the contact area with the air, accelerating the heat absorption and vaporization process of water inside the heat-absorbing copper tube 6. The heat-absorbing copper tube 6, with an inclination angle of 10–25°, helps the gaseous working fluid move to the heat dissipation copper tube 8. The air, pre-cooled by the evaporation unit 2 and dehumidified with the assistance of the heat-absorbing aluminum fins 10, enters the refrigeration dehumidification unit 4 for deep dehumidification. The hydrophilic treatment on the surface of the heat-absorbing aluminum fins 10 helps the rapid discharge of condensate, preventing water accumulation from affecting the dehumidification performance.

[0033] Fourth embodiment

[0034] Based on the first embodiment, the condensation mechanism 3 further includes heat dissipation aluminum fins 11. Several heat dissipation aluminum fins 11 are arranged in a rectangular array on the side of the heat dissipation copper tube 8, increasing the contact area between the condensation mechanism 3 and the low-temperature dry air, improving heat dissipation efficiency, accelerating the condensation rate of the gaseous working fluid, and enhancing heat recovery. The inclination angle of the heat dissipation copper tube 8 is 10–25°, which facilitates the movement of the liquid working fluid within the heat dissipation copper tube 8. The spacing between adjacent heat dissipation aluminum fins 11 is 1.3–1.8 mm, and the surface of the heat dissipation aluminum fins 11 is hydrophobic, which facilitates the drainage of condensate and ensures stable operation of the device.

[0035] Fifth embodiment

[0036] Based on the first embodiment, the top of the base 1 is provided with a V-shaped water guide groove 12, the evaporation mechanism 2, the condensation mechanism 3 and the refrigeration dehumidification mechanism 4 are all arranged in the water guide groove 12, and the bottom of the base 1 is provided with a drain hole 13 that communicates with the water guide groove 12.

[0037] High-temperature, high-humidity air flows sequentially through the evaporation unit 2, the refrigeration dehumidification unit 4, and the condensation unit 3. The condensate generated during dehumidification and heat recovery in each unit collects in a V-shaped water guide trough 12 at the top of the base 1. Because the V-shaped water guide trough 12 has a guiding function, the condensate flows along the trough 12 to the drain hole 13 at the bottom of the base 1, and is eventually discharged outside the device, ensuring the interior of the device remains dry and not affecting the normal operation of the dehumidification and heat recovery processes.

[0038] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
