Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of heat exchange, in particular to a water cooling machine evaporator. BACKGROUND

[0002] Because western countries are keen on taking cold water bath, so often need to install water cooling machine for bath bucket, to make a large amount of cold water.

[0003] The evaporator is one of the core components of the water cooling machine, and plays a crucial role in the entire refrigeration cycle. It exchanges heat with the refrigerant and water through the internal copper pipe, so that the refrigerant absorbs the heat in the water to achieve water cooling.

[0004] However, in actual use, the evaporator faces a serious problem, that is, the internal copper pipe surface is prone to scale accumulation. Because the water usually contains various minerals and impurities, when the water flows in the internal copper pipe surface of the evaporator and exchanges heat, with the change of water temperature and evaporation of water, the minerals in the water will gradually precipitate and adhere to the surface of the copper pipe, forming scale. Moreover, the internal structure of the evaporator of the water cooling machine is usually designed to be non-detachable. Although this non-detachable design ensures the sealing and structural stability of the evaporator to a certain extent, it brings great difficulty to the subsequent maintenance and cleaning work.

[0005] With the increase of use time, the scale will continue to accumulate and thicken, which will seriously hinder the heat transfer, resulting in a significant reduction in the heat exchange efficiency of the evaporator. In order to achieve the same refrigeration effect, the water cooling machine has to consume more energy to run, which not only increases the energy consumption and operating cost, but also may cause the refrigeration capacity of the water cooling machine to decline, unable to meet the actual production or use demand. Long-term operation in this high-load state will also accelerate the wear of other components of the water cooling machine, shorten the service life of the equipment, increase the maintenance frequency and maintenance cost of the equipment.

[0006] At present, for the cleaning of the scale inside the evaporator, chemical cleaning or high-pressure water flushing method is usually adopted. But due to the complex and non-detachable internal structure of the evaporator, these cleaning methods are often difficult to completely remove the scale on the surface of the copper pipe, especially the scale in some dead corners and gaps, and the cleaning effect is limited. Moreover, the chemical reagent used in the chemical cleaning process may cause corrosion to the copper pipe, affecting the performance and service life of the evaporator; high-pressure water flushing may damage the internal structure of the evaporator due to improper pressure control.

[0007] Therefore, in view of the problems existing in the prior art water cooling machine evaporator, the water cooling machine evaporator of the present application is proposed. UTILITY MODEL CONTENTS
