Description

Technical Field

[0001] This utility model relates to the field of air dehumidification system technology, and in particular to an air dehumidification system based on heat pipes. Background Technology

[0002] Special environments such as laboratories and high-precision manufacturing workshops often require controlled air humidity. Current technology typically uses cooling dehumidification to reduce humidity. While effective, this method also lowers air temperature, which can become too low and fail to meet temperature requirements. To address this, existing technology incorporates a temperature compensation device after the cooling dehumidification unit to heat the dehumidified air, bringing it back to the desired level. This method requires the temperature compensation device to operate at high power, resulting in high energy consumption. Utility Model Content

[0003] This invention provides an air dehumidification system based on heat pipes, which can use heat pipes to heat and cool the dehumidified air, thereby reducing energy consumption.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] This utility model provides an air dehumidification system based on heat pipes, including an air inlet channel, a heating channel, a heat pipe device, a cooling dehumidification device, and a temperature compensation device. The heating channel is located above the air inlet channel, and the tail end of the air inlet channel is connected to the heating channel. The heat pipe device includes multiple vertically arranged heat pipes, each heat pipe having a heat-releasing part and a heat-absorbing part. The heat-releasing part is located at the upper end of the heat pipe, and the heat-absorbing part is located at the lower end of the heat pipe. The heat pipe device passes through the top wall of the air inlet channel. The heat-releasing part and the temperature compensation device are located in the heating channel and are distributed sequentially along the airflow direction. The heat-absorbing part and the cooling dehumidification device are both located in the air inlet channel and are distributed along the airflow direction.

[0006] In some embodiments, the surface of the heat pipe is provided with heat exchange fins.

[0007] In some embodiments, the heat exchange fins are annular and surround the circumference of the heat pipe, and all heat exchange fins are distributed along the length of the heat pipe.

[0008] In some embodiments, the device further includes a compressor, the cooling and dehumidifying device is a dehumidifying evaporator, the temperature compensation device is a condenser, and the dehumidifying evaporator, compressor and condenser are connected in sequence.

[0009] In some embodiments, the system further includes a proportional valve and a radiator disposed outside the intake passage and the heating passage. The proportional valve has an inlet, a first outlet, and a second outlet. The compressor is connected to the inlet, the first outlet is connected to the condenser, and the second outlet is connected to the radiator.

[0010] In some embodiments, the cooling and dehumidifying device includes a cooling tank filled with ice water.

[0011] In some embodiments, the heat pipe device further includes an outer frame, the heat pipe is located inside the outer frame, and the top and bottom of the heat pipe are connected to the outer frame. The top wall of the air intake channel is provided with an opening communicating with the heating channel, and the heat pipe device passes through the opening.

[0012] In some embodiments, the heating channel has an air outlet, and a fan is provided inside the heating channel for blowing air towards the air outlet.

[0013] This invention has at least the following beneficial effects: Utilizing the characteristic of refrigerant in a heat pipe absorbing heat and rising, and releasing heat and descending, after dehumidified air enters the intake channel, the refrigerant in the heat-absorbing section is first heated, and then flows to the heat-releasing section. Next, the cooling and dehumidifying device cools and dehumidifies the air. The cooled and dehumidified air enters the heating channel, where the heat-releasing section releases heat, thereby heating the cooled air. The refrigerant, after releasing heat, flows back to the heat-absorbing section, where the temperature compensation device heats the air a second time. Thus, this invention can utilize the heat pipe to heat and cool the dehumidified air, reducing the power of the temperature compensation device and thereby reducing energy consumption.

[0024] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0025] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0027] An embodiment of this utility model provides an air dehumidification system based on a heat pipe, such as... Figure 1 As shown, it includes an air intake channel 110, a heating channel 120, a heat pipe device 200, a cooling and dehumidification device 300, and a temperature compensation device 400. The heating channel 120 is located above the air intake channel 110 to facilitate the arrangement of the heat pipe device 200. An air inlet is provided at the beginning of the air intake channel 110 to allow air to enter, and the end of the air intake channel 110 is connected to the heating channel 120, allowing air in the air intake channel 110 to flow into the heating channel 120.

[0028] The heat pipe device 200 includes multiple heat pipes 210, each containing a refrigerant that can flow along it. The heat pipes 210 can be vertically oriented and each has a heat-dissipating section 212 and a heat-absorbing section 211. The heat-dissipating section 212 is located at the upper end of the heat pipe 210, and the heat-absorbing section 211 is located at the lower end. The heat pipe device 200 passes through the top wall of the air intake channel 110. The heat-dissipating section 212 and the temperature compensation device 400 are located in the heating channel 120, sequentially distributed along the airflow direction. The heat-absorbing section 211 and the cooling and dehumidifying device 300 are both located in the air intake channel 110, and are also distributed along the airflow direction.

[0029] The refrigerant inside the heat pipe 210 can flow upwards after being heated and downwards after being released from heat; this is an inherent characteristic of heat pipes. After indoor air enters the intake channel 110, it first comes into contact with the heat absorption section 211. Indoor air is generally 23-25°C, which heats the heat absorption section 211. The refrigerant in the heat absorption section 211 flows upwards along the heat pipe 210 to the heat release section 212. After absorbing heat in the heat absorption section 211, the air temperature generally drops to 15-18°C. Then, the air continues to flow along the intake channel 110 to the cooling and dehumidifying device 300, which cools and dehumidifies the air, further reducing its temperature to 3-12°C. The cooled air then flows to the heating channel 120 and first comes into contact with the heat release section 212. Because the refrigerant in the heat release section 212 is at a higher temperature, it can exchange heat with the cooled air, thus heating the air to a temperature generally of 15-20°C. Then, the temperature compensation device 400 can reheat the air, typically to 23-25°C. The cooled refrigerant then flows downward to the heat absorption section 211, thus allowing the refrigerant to be recycled to heat the dehumidified air. This effectively utilizes the characteristics of the heat pipe, reducing the power consumption of the temperature compensation device 400 compared to existing technologies, thereby lowering energy consumption.

[0030] Meanwhile, after the indoor air enters the air intake channel 110, it first exchanges heat with the heat absorption section 211, which can initially reduce the air temperature. The cooling and dehumidifying device 300 can then condense and dehumidify the air from a lower temperature, which also reduces the power of the cooling and dehumidifying device 300 and reduces the overall energy consumption of the entire air dehumidification system.

[0031] It should be noted that heat pipe 210 is existing technology, and its internal structure will not be described in detail. For example, heat pipe 210 can be a four-dimensional heat pipe, which is an existing technology.

[0032] In some embodiments, such as Figure 1 and Figure 3As shown, heat exchange fins 240 are provided on the surface of heat pipe 210 to increase the heat exchange area and improve heat exchange efficiency.

[0033] Furthermore, the heat exchange fins 240 are annular and surround the circumference of the heat pipe 210, with all heat exchange fins 240 distributed along the length of the heat pipe 210. This distribution of heat exchange fins 240 is more rational and can further improve the heat exchange effect. Specifically, all heat exchange fins 240 can be evenly distributed along the length of the heat pipe 210.

[0034] In some embodiments, such as Figure 1 and Figure 2 As shown, the air dehumidification system with heat pipe in this embodiment also includes a compressor 430, a cooling dehumidification device 300 which is a dehumidifying evaporator, and a temperature compensation device 400 which is a condenser 410. The dehumidifying evaporator, compressor 430 and condenser 410 are connected in sequence.

[0035] The dehumidifying evaporator, compressor 430, and condenser 410 form an air conditioning-like system. The dehumidifying evaporator dehumidifies the air by cooling and condensing, while the condenser 410 heats the air by dissipating heat. This allows the dehumidifying evaporator to continuously cool and dehumidify the air. Furthermore, since the temperature compensation device 400 is part of the same system as the dehumidifying evaporator, no additional energy supply is required for it, further reducing system energy consumption.

[0036] Furthermore, the air dehumidification system with heat pipes in this embodiment also includes a proportional valve 450 and a radiator 420 disposed outside the air intake channel 110 and the heating channel 120. The radiator 420 is neither located in the air intake channel 110 nor in the heating channel 120, effectively dissipating heat externally. The proportional valve 450 has an inlet, a first outlet, and a second outlet. The flow rates of the first outlet and the second outlet can be adjusted through the proportional valve 450. The compressor 430 is connected to the inlet, the first outlet is connected to the condenser 410, and the second outlet is connected to the radiator 420.

[0037] The proportional valve 450 can adjust the flow rates of the first and second outlets. When the flow rate at the first outlet is higher, more high-temperature refrigerant can flow to the condenser 410, thus providing more heat to the dehumidified air, increasing the heating effect, and significantly raising the air temperature. Conversely, when the flow rate at the first outlet is lower, less high-temperature refrigerant can flow to the condenser 410, thus providing less heat to the dehumidified air, reducing the heating effect, and slightly lowering the air temperature. Therefore, in this embodiment, the proportional valve 450 can be used to adjust the air temperature to meet the needs of different scenarios.

[0038] In other embodiments, the cooling and dehumidifying device includes a cooling tank filled with ice water. Refrigerant can be used directly to achieve condensation dehumidification; once the ice water is produced, no further electricity is needed, thus reducing energy consumption.

[0039] In some embodiments, such as Figure 1 and Figure 3 As shown, the heat pipe device 200 also includes an outer frame 220. The heat pipe 210 is located inside the outer frame 220, and the top and bottom of the heat pipe 210 are connected to the outer frame 220. The outer frame 220 is used to fix the heat pipe 210. Air can flow through the gap between adjacent heat pipes 210. The top wall of the air inlet channel 110 is provided with an opening communicating with the heating channel 120. The heat pipe device 200 passes through the opening, so that the heat-releasing part 212 can be arranged in the heating channel 120, and the heat-absorbing part 211 can be arranged in the air inlet channel 110.

[0040] Furthermore, a heat insulation plate 230 is fitted onto the outside of the heat pipe 210. The heat insulation plate 230 seals the opening to prevent air in the air intake channel 110 from flowing directly into the heating channel 120 through the opening, thus improving the sealing performance. At the same time, the heat insulation plate 230 positions the heat pipe 210, making it less prone to bending or deformation, and ensuring its heat exchange effect.

[0041] Furthermore, both ends of the heat insulation plate 230 can be connected to the outer frame 220 to stably fix the heat insulation plate 230.

[0042] In some embodiments, such as Figure 1 As shown, the heating channel 120 has an air outlet 121, and a fan 500 is installed inside the heating channel 120 to blow air towards the air outlet 121. The heated and dehumidified air can then be blown into the room from the air outlet 121. At the same time, under the action of airflow, the air can pass more smoothly through the air inlet channel 110 and the heating channel 120 in sequence.

[0043] Furthermore, the fan 500, the heat dissipation section 212, and the temperature compensation device 400 are distributed along the airflow direction to guide the airflow to flow rapidly.

[0044] In some embodiments, such as Figure 1 As shown, the heat pipe-based air dehumidification system also includes a housing 10, in which an air intake channel 110 and a heating channel 120 are formed as described in the above embodiment. An air outlet 121 may be provided on the top surface of the housing 10, and an air inlet communicating with the air intake channel 110 may be provided on the side surface of the housing 10.

[0045] Furthermore, a filter screen can be installed at the air inlet to filter the air, reduce impurities entering the air intake channel 110, and improve the cleanliness of the air.

Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
