Description

Technical Field

[0001] The utility model relates to the field of heat exchange devices, and more specifically, to a heat exchange device for spray-type enhanced heat exchange. Background Technique

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid. Also known as... This heat exchanger fixes the heat exchange tubes in rows on a steel frame. The hot fluid flows inside the tubes, and cooling water is evenly sprayed down from the upper spraying device above, so it is also called a spray cooler. Most of these heat exchangers are placed in places with air circulation, and the evaporation of the cooling water also takes away part of the heat, which can play a role in reducing the temperature of the cooling water and increasing the heat transfer driving force. Therefore, the heat transfer effect of the spray heat exchanger has been greatly improved.

[0003] During the operation of the spray heat exchange device, the inside of the heat exchange tubes is in long-term contact with water flow, and scale deposits are likely to accumulate inside. Excessive accumulation of scale deposits in the heat exchange tubes will cause a risk of blockage inside, making the penetration of the water flow not smooth enough, which is not conducive to ensuring the heat exchange intensity of the heat exchange tubes as a heat exchange mechanism. Therefore, it is necessary to design a heat exchange device for spray-type enhanced heat exchange to solve the above problems. Summary of the Utility Model

[0004] 1. Technical Problems to be Solved

The wire ropes that are flexibly wound outside the electric winding shafts can make the inner ring sliding circle between the two scrape and fit inside the heat exchange tubes, which is beneficial to making the penetration of the water flow smoother, and further ensuring the heat exchange efficiency of the heat exchange tubes as a heat exchange mechanism.
