Problems solved by technology

[0007] Among these four methods of defogging, the first and second methods are relatively simple to implement, but the effect of defogging is not ideal; The investment is higher, and the bearing capacity of the tower foundation is greatly increased
The fourth anti-fog method has relatively low investment and less increase in the bearing capacity of the tower foundation. The ideal installation and design of the partition wall heat exchanger can achieve the ideal effect of fog elimination and water saving, but the design of the partition wall heat exchanger is more difficult. High, the current market is less used, and the effect of fog elimination and water saving is not ideal

Abstract

The invention relates to the technical field of counter-flow cooling towers, in particular to a graphene cross-flow air cooler. The graphene cross-flow air cooler is designed according to the working principle of a cross-flow plate heat exchanger. Heat exchange plates are formed by compression molding of modified PVC sheets with good hydrophilicity, and welding between the plates is completed by a unique high-frequency welding technology, so that leakage of cold and hot air is avoided. The graphene cross-flow air cooler has good fog dissipation and water saving effects, and is fast in heat conduction, high in heat exchange efficiency, resistant to corrosion, light in weight and long in service life. The graphene cross-flow air cooler comprises a plurality of graphene modified heat exchange layers, each graphene modified heat exchange layer comprises two graphene modified PVC heat exchange plates, an epitaxial wafer is arranged in the edge area of each graphene modified PVC heat exchange plate, the two graphene modified PVC heat exchange plates are fixedly connected through the epitaxial wafers opposite in position to form a first passage, and the graphene modified heat exchange layers are fixedly connected through the epitaxial wafers between the two adjacent graphene modified PVC heat exchange plates to form a plurality of second passages.

Description

technical field [0001] The invention relates to the technical field of counter-flow cooling towers, in particular to a graphene cross-flow air cooler. Background technique [0002] As we all know, in the cold northern region, when the mechanical ventilation cooling tower operates in winter, the hot and humid saturated air coming out of the tower mixes with the cold air outside the tower, and due to cooling and condensation, a fog group containing a large number of fine liquid particles is formed. The traditional mechanical ventilation cooling tower During operation, the cold air exchanges heat with water inside the cooling tower to generate nearly saturated hot and humid air. After leaving the tower, the hot and humid air mixes with the cold air, cools and condenses into a mist containing many tiny droplets, causing water At the same time, due to the low height of the mechanical ventilation cooling tower, the drift of fog will affect the life of surrounding residential areas...
