Spring tube evaporation type cold exchange device

Abstract

The present invention relates to a elastic distortion tube evaporation type heat exchange device comprising heat exchange coiled tube, case, blower, intake grille, water blocking grate, spraying unit, water pump and water collecting sump. It features that the coiled tube consists of straight tube and bent tube, the straight tube is elastic distortion tube and in an angle of 0-15 deg to the horizontal plane; and the bent tube is circular tube. The present invention has more heat transferring coiled tubes and great heat capacity in unit, high water film forming capacity in heat transferring tube, high water film covering rate, fast water film updating course, powerful heat exchange capacity and less flow resistance.

Description

technical field [0001] The invention belongs to the field of refrigeration and air-conditioning equipment, and relates to evaporative heat exchange equipment, in particular to an elastic tube evaporative cold exchange equipment. Background technique [0002] In the evaporative cooling equipment, the heat exchange coil is the key component. Inside the coil is the cooled (condensed) fluid, and outside the coil is water and air flow and heat and mass transfer. The distribution of water and air, especially the water film The state directly determines the heat exchange efficiency, and the distribution state of water and air has a great relationship with the type, shape and arrangement of the coil. Existing evaporative cooling equipment, the heat exchange coil adopts circular tube, oval tube, alternating surface corrugated tube, different drop-shaped tube, tapered arc tube, etc., the heat capacity of the circular tube is limited, and the heat exchange ef...

AI Technical Summary

Problems solved by technology

Existing evaporative cooling equipment, the heat exchange coil adopts circular tube, oval tube, alternating surface corrugated tube, different drop-shaped tube, tapered arc tube, etc., the heat capacity of the circular tube is limited, and the heat exchange efficiency is not high. High, large flow resistance, other tube types can improve the heat capacity and heat transfer efficiency of the coil to a certain extent, and reduce the air flow resistance

However, due to the inherent shape of the existing coils, the arrangement of the coils is relatively loose, and the improvement of the heat capacity is limited; The surface renewal process is slow, resulting in a rapid rise in water temperature, and the continuous heat exchange capacity of the cooling equipment is not strong; the water film is difficult to fall off from the bottom surface of the tube after the heat exchange is completed on the surface of the coil, and the water redistribution ability is not strong; the coils are not Completely streamlined design, according to the principle of fluid dynamics, its resistance has not yet reached the minimum, the air is easy to form a vortex in the cooling equipment, which not only increases energy consumption, but also causes the local temperature of the air flow to be too high, affecting the heat exchange efficiency
