A multi-channel duct dehumidifier

Abstract

This utility model discloses a multi-channel duct dehumidifier, which includes a support frame, a cover plate, an exchange chamber, an inlet pipe, an outlet pipe, and a drain pipe. This multi-channel duct dehumidifier uses metal pipes directly welded to the exchange chamber. Due to the good thermal conductivity of the metal pipes, they can also maintain a low temperature like the exchange chamber, thereby increasing the cooling path of the gas flow and improving the dehumidification effect. A spiral rod is added at the air inlet, so that the inflowing gas does not flow out directly through the flow channel, but rather flows out through the rotation of the spiral rod. This design increases the residence time and flow path of the gas in the exchange chamber, allowing for more thorough contact between the gas and the low-temperature components, thus improving the dehumidification effect. Furthermore, increasing the number of pipes allows for handling different gas flow rates when used individually, and when used in series, it further increases the cooling path and contact time of the gas, greatly enhancing the dehumidification effect.

Description

Technical Field

[0001] This utility model relates to the field of dehumidification equipment technology, and in particular to a multi-channel duct dehumidifier. Background Technology

[0002] In industrial production, warehousing and logistics, and certain indoor environments, controlling air humidity is crucial. Excessive humidity can lead to equipment damage, product spoilage, and mold growth. Duct dehumidifiers, as an effective dehumidification device, are widely used in these scenarios.

[0003] Existing ducted dehumidifiers often suffer from poor dehumidification performance. The main reason for this is the short cooling path the gas travels through, resulting in insufficient heat exchange between the gas and the cooling components, thus hindering the effective condensation of moisture from the air. Furthermore, some ducted dehumidifiers use rubber hoses connecting to the exchange chamber. These hoses have poor thermal conductivity and cannot maintain the same low temperature as the exchange chamber, further impacting dehumidification efficiency. Moreover, existing ducted dehumidifiers have a limited and fixed channel configuration, restricting flexibility to adapt to specific needs and limiting improvements in dehumidification performance.

[0007] The exchange chamber is provided with an air inlet, an air outlet, and a drain outlet. The bracket is equipped with an air inlet pipe connector, an air outlet pipe connector, and a drain pipe connector.

Furthermore, the increased number of pipes allows for both individual and series use. Individual pipes can handle different gas flow rates as needed, while series use further increases the cooling path and contact time of the gas, significantly enhancing the dehumidification effect.

[0027] Reference Figures 1 to 5This invention relates to a multi-channel duct dehumidifier, as described in some embodiments of the present invention. The dehumidifier includes a support 1, a cover plate 2, an exchange chamber 3, an air inlet pipe 4, an air outlet pipe 5, and a drain pipe 6. The support 1 has a receiving cavity, and the cover plate 2 covers the top of the support 1. The exchange chamber 3, air inlet pipe 4, air outlet pipe 5, and drain pipe 6 are all disposed within the receiving cavity. All three pipes are metal. The exchange chamber 3 has an air inlet 31, an air outlet 32, and a drain outlet 33. The support 1 is equipped with an air inlet pipe connector 11, an air outlet pipe connector 12, and a drain pipe connector 13. The two ends of the air inlet pipe 4 are connected to the air inlet 31 and the air inlet pipe connector 11, respectively. The two ends of the air outlet pipe 5 are connected to the air outlet 32 ​​and the air outlet pipe connector 12, respectively. The two ends of the drain pipe 6 are connected to the drain outlet 33 and the drain pipe connector 13, respectively. A spiral rod 7 is also installed at the air inlet 31. The number of air intake pipe 4, air outlet pipe 5, and drain pipe 6 is at least two.

[0028] Specifically, the support 1 is a hollow shell structure with a receiving cavity. A cover plate 2 is placed on top of the support 1, and the exchange chamber 3 is located within the receiving cavity. This structural design provides a stable installation space for the exchange chamber 3, while the cover plate 2 seals and protects the receiving cavity, preventing external impurities from entering. The inlet pipe 4, outlet pipe 5, and drain pipe 6 are all metal pipes. Metal pipes have excellent thermal conductivity and, compared to traditional rubber hoses, can better transfer cold energy, thus improving dehumidification. Replacing the previous rubber hoses with metal pipes allows the metal pipes to maintain a low temperature, similar to the exchange chamber, thereby increasing the cooling path for gas flow and improving dehumidification. More specifically, the inlet pipe connector 11, outlet pipe connector 12, and drain pipe connector 13 are located on the outside of the support 1, while the inlet pipe 4, outlet pipe 5, and drain pipe 6 are located within the receiving cavity. The arrangement of the air inlets and connectors, through this connection method, forms a complete gas flow and drainage path, ensuring the smooth operation of the dehumidification process. Figure 5 As shown, a spiral rod 7 is also installed at the air inlet 31. Part of the spiral rod 7 is located inside the air inlet pipe 4 and part is located inside the exchange chamber 3. The spiral rod 7 can change the flow state of the gas, causing the gas to rotate and flow in, increasing the cooling path through which the gas flows, thereby improving the dehumidification effect.

[0029] In this embodiment, as Figures 3 to 5As shown, there are two inlet pipes 4, two outlet pipes 5, and two drain pipes 6. Correspondingly, there are also two inlet ports 31, two outlet ports 32, and two drain ports 33. Inlet ports 31 and 32 are located on the same side of the exchange chamber 3, while drain ports 33 are located on the other side. Each inlet pipe 4, outlet pipe 5, and drain pipe 6 forms a single pipe structure. The arrangement of two inlet ports 31, two outlet ports 32, and two drain ports 33, along with the corresponding pipes, forms two sets of "H"-shaped pipe structures. These two sets of pipes can be used individually or in series. When used individually, they can dehumidify different areas or different flow rates of gas as needed. When used in series, the gas can pass through a longer cooling path, further improving the dehumidification effect and greatly enhancing the flexibility and dehumidification capacity of the equipment. In other embodiments, the number of pipes can be adjusted according to actual conditions, and there can be three or more sets.

[0030] In addition, the air inlet pipe 4, air outlet pipe 5, and drain pipe 6 are all welded to the heat exchange chamber 3. The welding connection method has the advantages of strong connection and good sealing, which can ensure the connection strength and sealing between the pipe and the heat exchange chamber 3, avoid gas or liquid leakage, and also facilitate heat transfer, ensuring that the metal pipe can be kept at a low temperature like the heat exchange chamber 3, thereby improving heat exchange efficiency.

[0031] The inlet pipe connector 11, the outlet pipe connector 12, and the drain pipe connector 13 are all quick-connect couplings. The use of quick-connect couplings makes the connection and disassembly of pipes more convenient and faster, which is beneficial to the installation, maintenance, and repair of equipment.

[0032] The gaps in the receiving cavity are filled with foamed material. Specifically, the gaps between the aforementioned pipes, the exchange chamber 3, and the receiving cavity are filled with foamed material. This foamed material has excellent thermal insulation properties, reducing heat exchange between the exchange chamber 3 and the external environment, ensuring that the exchange chamber 3 and the metal pipes maintain a lower temperature, thereby improving dehumidification efficiency and reducing energy consumption. The cover plate 2 is equipped with a foamed material injection port 21. Foamed material can be easily injected into the gaps in the receiving cavity through the injection port 21, making the operation simple and convenient, and beneficial for equipment production and maintenance.

[0033] The multi-channel duct dehumidifier also includes a cooling plate 81 located at the bottom of the exchange chamber 3. The cooling plate 81 provides cooling to the exchange chamber 3, maintaining it at a low temperature, thereby cooling and dehumidifying the gas entering the exchange chamber 3. The multi-channel duct dehumidifier also includes a radiator 82 located at the bottom of the cooling plate 81. During operation, the cooling plate 81 generates heat, which the radiator 82 dissipates promptly, ensuring the normal operation of the cooling plate 81 and improving cooling efficiency. The multi-channel duct dehumidifier also includes a DC fan 83 located at the bottom of the radiator 82. The DC fan 83 accelerates airflow, enhancing the heat dissipation effect of the radiator 82 and ensuring the cooling plate 81 remains in good working condition. The multi-channel duct dehumidifier also includes a fan guard 84 covering the DC fan 83. The fan guard 84 prevents external dust and debris from entering the DC fan 83, protecting the equipment components and extending its service life.

[0034] The multi-channel duct dehumidifier provided in this application adopts several improvement schemes to enhance the dehumidification effect:

[0035] 1. Metal pipes are directly welded to the heat exchange chamber, replacing the previous rubber hoses. Because metal pipes have excellent thermal conductivity, they can also maintain a low temperature, similar to the heat exchange chamber, thus increasing the cooling path for the gas flow and improving dehumidification efficiency.

[0036] 2. A spiral rod 7 is added at the air inlet 31, so that the inflowing gas does not flow out directly through the flow channel, but flows out through the rotation of the spiral rod 7. This design increases the residence time and flow path of the gas in the exchange chamber 3, making the gas contact with the low-temperature components more sufficient, thereby improving the dehumidification effect;

[0037] 3. Increase the number of pipes; multiple sets of pipes can be used individually or in series. When used individually, they can handle different gas flow rates as needed. When used in series, they can further increase the gas cooling path and contact time, greatly improving the dehumidification effect.

[0038] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
