Description

TECHNICAL FIELD

[0001] The present application relates to the field of air treatment, in particular to a heat pipe type direct evaporative cooling water unit based on solution dehumidification. BACKGROUND

[0002] In the field of air treatment, especially in industrial production, commercial buildings and precision environments, the demand for air dehumidification and cooling is increasingly stringent. The traditional air treatment equipment often has the problems of separation of dehumidification and cooling links and low integration, resulting in large equipment size, high space occupancy rate, and the need for additional pipeline connection between each functional module, increasing the installation complexity and leakage risk.

[0003] The existing solution dehumidification equipment has limited solution and air contact area, low dehumidification efficiency, and solution backflow phenomenon due to pressure fluctuation during solution transportation, affecting the stability of the spray, resulting in unstable dehumidification effect. At the same time, the solution recycling rate is low, and a large amount of solution not involved in dehumidification is directly discharged, which not only wastes resources but also increases operating costs.

[0004] In the cooling link, the traditional air-cooled or water-cooled method has the defects of low heat exchange efficiency and high energy consumption. Although some equipment uses heat pipe technology to achieve cooling, the combination of heat pipe and dehumidification system is not close enough, and the heat exchange is not sufficient, resulting in poor cooling effect. In addition, there is a lack of effective heat dissipation structure, which is prone to problems such as high equipment operating temperature and instability.

[0005] Therefore, it has become a technical problem to be solved in the field to develop an air treatment equipment with high integration, good dehumidification and cooling effect, high solution utilization rate, stable operation and strong adaptability. SUMMARY
