Embodiment 1

[0045] This embodiment is based on the vertical heat exchanger equipment and system of the dry section of the water-saving and fog-eliminating cooling tower based on the micro heat pipe array. The heat exchange unit of the vertical heat exchanger is as follows figure 1 As shown, the air-cooled finned air duct 2 is pasted on the outer wall of the micro heat pipe array 1. The thickness of the micro heat pipe array is 5mm and the width is 30mm. According to the application requirements, the thickness of the micro heat pipe array is 0.3-15mm and the width is 10mm. -120mm can also be adjusted. The single hole size of the finned air duct is above 5mm, which reduces the flow resistance on the air side and reduces the risk of blockage. The bonded parts are pasted and tightly compacted with thermally conductive silica gel with high thermal conductivity. According to the process requirements, they can also be directly welded together by brazing. The above-mentioned one micro heat pipe ...

Embodiment 2

[0050] This embodiment is based on the horizontal heat exchanger equipment and system of the dry section of the water-saving and fog-eliminating cooling tower based on the micro heat pipe array. The heat exchange unit of the horizontal heat exchanger is as follows Figure 5 As shown, the air-cooled finned air ducts 2 are attached to the two side walls of the vertically placed micro heat pipe array 1. According to the use requirements, the thickness of the micro heat pipe array can be adjusted between 0.3-15mm and the width between 10mm-120mm. The single hole size of the finned air duct is above 5mm, which reduces the flow resistance on the air side and reduces the risk of blockage. The bonded parts are pasted and tightly compacted with thermally conductive silica gel with high thermal conductivity, and can also be directly welded together by brazing process according to process requirements. The heat exchange unit 13 is composed of one micro heat pipe array 1 and multiple air-...

Abstract

The invention provides a water-saving fog dissipation cooling tower device and system based on micro heat pipe arrays. The water-saving fog dissipation cooling tower device comprises a plurality of sets of air-water type air cooler modules, wherein each module comprises heat exchange units and porous channel parallel flow water pipes, each heat exchange unit comprises a micro heat pipe array and an air cooling fin air pipe attached to the outer side wall face of the micro heat pipe array, the direction of the porous channel parallel flow water pipes intersects with the direction of the micro heat pipe arrays, the micro heat pipe arrays are attached to the wall faces of the porous channel parallel flow water pipes, the part, attached to the corresponding porous channel parallel flow water pipe, of each micro heat pipe array is an evaporation section, the other part is a condensation section, and the air cooling fin air pipes lead to a dry section of the cooling tower. The characteristics of small thermal resistance and high heat exchange efficiency of the flat plate micro heat pipe arrays are utilized to effectively combine efficient micro heat pipe array assemblies with porous channel parallel flow pipe assemblies, so that the heat exchange area is increased, and the effect of enhancing heat transfer is achieved. Dry air and wet air are mixed to reduce the unsaturation degree, so that the purposes of saving water resources, saving energy and dissipating fog are achieved.

Description

technical field [0001] The invention relates to a water-saving and fog-eliminating cooling tower heat exchange equipment and system, belonging to the field of enhanced heat exchange and energy saving. Background technique [0002] my country's water resources are scarce, and water conservation has become a problem that social development must face. However, industrial water intake is huge, accounting for about a quarter of the total water intake of the whole society, and industrial cooling water exceeds 80% of the total industrial water consumption. The cooling tower is a key device in the industrial cooling water circulation process. During the circulation process, the cooling water transfers heat and mass with the air in the tower, but physical processes such as evaporation, wind blowing, and sewage discharge inevitably occur, which results in the formation of a large amount of cooling water. main factor of the loss. At the same time, the water mist pollution at the outle...
