Abstract
Description
Technical Field
[0001] This application relates to the field of heat exchanger technology, and more specifically, to a dehumidification structure for a plate heat exchanger unit. Background Technology
[0002] Plate heat exchanger units are a common type of heat exchange equipment, mainly composed of plate heat exchangers, circulating pumps, control valves, instruments, and other auxiliary equipment. They are used to achieve heat exchange between two or more fluids. Plate heat exchanger units have advantages such as compact structure, high heat transfer efficiency, easy cleaning, energy saving, and environmental protection. They are widely used in heat exchange applications in petroleum, chemical, food, pharmaceutical, heating, and air conditioning industries.
[0003] In related technologies, to achieve dehumidification in heat exchange units, for example, patent CN221948628U provides a dehumidification device for water-cooled units. This device, by assembling heat sinks, simultaneously performs heat exchange while a condenser fan is turned on. Air enters from the intake pipe and exits from the exhaust pipe, forming a circulation. Simultaneously, the heat sinks cool the humid air. After the fan cools the air near the plate heat exchanger, the water vapor in the humid air accumulates as condensate and flows out from the drain pipe. It features low cost, high heat exchange efficiency, low heat loss, compact and lightweight structure, compact space, and long service life.
[0004] Although the existing technical solutions mentioned above can achieve the effect of cooling humid air by setting up a condenser fan, after the condenser fan cools down the air near the heat exchanger, the condensate on the surface of the heat exchanger needs to accumulate for a period of time before it flows down. Before the condensate flows down, a water film will form on the surface of the heat exchanger, which will affect the heat exchange efficiency of the heat exchanger.
[0005] In view of this, we propose a dehumidification structure for plate heat exchanger units. Utility Model Content

[0032] The present application will be further described in detail below with reference to the accompanying drawings.
[0033] Reference Figure 2 and Figure 3 This application discloses a dehumidification structure for a plate heat exchanger unit, including a unit box 1. A condenser fan 12 is fixedly installed on the outside of the unit box 1. Multiple heat exchange plates 2 are fixedly installed on the outside of the unit box 1. The multiple heat exchange plates 2 are used to achieve the heat exchange effect of the gas. A cleaning component 3 is installed on the outside of the multiple heat exchange plates 2. The cleaning component 3 includes multiple cleaning discs 31. Cleaning rods 32 are fixedly installed on both sides of the multiple cleaning discs 31. The multiple cleaning rods 32 are used to clean the surface of the multiple heat exchange plates 2.
[0034] During use, air enters the equipment and passes through the condenser fan 12 and multiple heat exchange plates 2. The air is condensed by the condenser fan 12 and multiple heat exchange plates 2, and the multiple heat exchange plates 2 complete the heat exchange effect. The air after heat exchange is discharged. After a period of use, the condensate formed on the outside of the heat exchange plates 2. The multiple cleaning discs 31 are rotated periodically, and the cleaning rods 32 on both sides of the multiple cleaning discs 31 clean the condensate film on the outside of the heat exchange plates 2 to ensure the heat exchange efficiency of the multiple heat exchange plates 2.
[0035] Reference Figure 2 - Figure 7 Multiple cleaning discs 31 are fixedly mounted on the inner side of a drive rod 34. The outer side of the drive rod 34 is fixedly mounted to the output end of the drive motor 33. Multiple heat exchange plates 2 are provided with a protective cover 4 on the top and multiple liner plates 5 are fixedly mounted on the bottom. An air inlet pipe 11 is provided on the inner side of the unit box plate 1. One end of the air inlet pipe 11 is fixedly mounted to the input end of the condenser fan 12. A condenser cover 13 is fixedly mounted on the output end of the condenser fan 12. The condenser cover 13 is fixedly mounted to the outer side of the protective cover 4. An exhaust pipe 14 is fixedly mounted on the end of the condenser cover 13 away from the condenser fan 12. Multiple heat exchange plates 2 are provided with a liquid inlet pipe 21 and a liquid outlet pipe 22 on the inner side. The liquid inlet pipe 21 and the liquid outlet pipe 22 are used to ensure the circulation of coolant inside the multiple heat exchange plates 2. Multiple heat exchange plates 2 are provided with grooves 23 on the inner side and support grooves 24 on the bottom.
[0036] Air is introduced into the equipment through the air inlet pipe 11. The air passes through the condenser fan 12 and then goes to multiple heat exchange plates 2 for heat exchange. The air is then discharged through the exhaust pipe 14. The condenser shroud 13 ensures that the air does not leak to the outside and that the air is in full contact with the multiple heat exchange plates 2. The multiple heat exchange plates 2 are connected together through the liquid inlet pipe 21 and the liquid outlet pipe 22. The liquid inlet pipe 21 is connected to an external liquid supply device that can supply coolant to the inside of the multiple heat exchange plates 2. The liquid supply device is a prior art structure and will not be described in detail. The coolant is fed into the liquid outlet pipe 22 through the groove 23 and discharged through the liquid outlet pipe 22, completing the circulation of the coolant.
[0037] After a period of use, a layer of water film will be attached to the outside of the heat exchange plate 2. Periodically, the drive rod 34 is driven by the drive motor 33 to rotate once, so that the drive rod 34 drives multiple cleaning discs 31 to rotate once, thereby allowing multiple cleaning rods 32 to clean the water film on the outside of multiple heat exchange plates 2.
[0038] At the same time, the multiple cleaning rods 32 rotate once to reset, so that the multiple cleaning rods 32 cooperate with the cleaning disc 31 to fill the gaps between the multiple liners 5, ensuring that air can only enter and exit from the part of the multiple heat exchange plates 2 located at the bottom of the protective cover 4 and the top of the liners 5. The inner side of the protective cover 4 is provided with multiple baffles that match the multiple heat exchange plates 2 to prevent air from entering the interior of the protective cover 4 and affecting the heat exchange effect of the multiple heat exchange plates 2.
[0039] Reference Figure 1 and Figure 2 Multiple liner plates 5 are detachably mounted on the inner side by several connecting bolts 51. Multiple liner plates 5 are detachably mounted on the outer side of the unit box plate 1 by several fixing bolts E52. The outermost liner plate 5 is fixedly mounted on the outer side with a fixing seat 53. The drive motor 33 is detachably mounted on the fixing seat 53. The inner side of the condenser fan 12 is detachably mounted on the outer side of the unit box plate 1 by several fixing bolts A121. Both ends of the condenser cover 13 are detachably mounted on the output end of the condenser fan 12 and one end of the exhaust pipe 14 by several fixing bolts B131, respectively. The outer side of the unit box plate 1 is detachably mounted on the outer side with several fixing bolts C151. The protective cover 4 is detachably mounted on the outer side of the unit box plate 1 by several fixing bolts D41.
[0040] The unit housing 15 can be disassembled using several fixing bolts C151 to facilitate maintenance of the internal structure of the unit housing 15. The drive motor 33 can be disassembled from the mounting base 53. Several fixing bolts E52 can be used to remove multiple liner plates 5 from the outside of the unit housing 1. Several connecting bolts 51 can be used to remove multiple liner plates 5 for maintenance. Several fixing bolts A121 and several fixing bolts B131 can be used to remove the condenser fan 12 from the outside of the unit housing 1 for maintenance. Several fixing bolts B131 on both sides can be used to remove the condenser cover 13 for maintenance of the internal structure of the condenser cover 13.
[0041] In summary, the dehumidification structure of the plate heat exchanger unit disclosed in this application allows air to be introduced into the equipment through the air inlet pipe 11 during use. The air passes through the condenser fan 12 and then reaches multiple heat exchange plates 2 for heat exchange. Subsequently, the air is discharged through the exhaust pipe 14. The condenser shroud 13 ensures that the air does not leak to the outside, allowing the air to fully contact the multiple heat exchange plates 2. The multiple heat exchange plates 2 are connected together through the liquid inlet pipe 21 and the liquid outlet pipe 22. The liquid inlet pipe 21 is connected to an external liquid supply device, which can input coolant into the inside of the multiple heat exchange plates 2. The liquid supply device is a prior art structure and will not be described in detail. The coolant is input into the liquid outlet pipe 22 through the groove 23 and discharged through the liquid outlet pipe 22, completing the circulation of the coolant.
[0042] After a period of use, a layer of water film will adhere to the outside of the heat exchange plate 2. Periodically, the drive rod 34 is driven by the drive motor 33 to rotate once, so that the drive rod 34 drives multiple cleaning discs 31 to rotate once, thereby allowing multiple cleaning rods 32 to clean the water film on the outside of multiple heat exchange plates 2.
