Efficient heat exchange tube fin for filler coupling coil evaporative condenser

Abstract

A high-efficient heat exchange tube piece for a filler coupling coil evaporative condenser comprises a coil (1) formed of heat exchange tubes coiled into an S shape. The coil (1) is provided with at least one layer of filler (2) for guiding spraying cooling water to flow from an upper layer heat exchange tube to a lower layer heat exchange tube. The filler (2) is arranged between adjacent heat exchange tubes (11), and connects the heat exchange tubes (11) to form a continuous water flow surface. The heat exchange tube is capable of lowering the temperature of cooling water in a cooling coil, and improving water distribution coverage of cooling water sprayed from the cooling coil and the heat exchange efficiency.

Description

technical field [0001] The invention relates to the field of heat exchange equipment, in particular to a high-efficiency heat exchange tube sheet for a coil evaporative condenser. Background technique [0002] At this stage, evaporative condensers on the market usually use coiled heat exchange tubes to form a heat exchanger. The outer surface of the heat exchanger is cooled by spraying water, and the circulating spraying water is used to evaporate the air and take away the heat. Since there is no medium between the upper and lower tubes of the coil to guide the cooling water flow, when the cooling water falls from top to bottom, under the traction of the vertical wind direction, the cooling water flutters disorderly and easily produces flying water, and the water distribution on the coil is uneven. It is easy to store dry spots, reduces heat exchange capacity and has the risk of fouling, and also has the disadvantages of low heat exchange efficiency, more heat exchanger con...

AI Technical Summary

Problems solved by technology

In a traditional evaporative condenser, the length and spacing of the heat exchange tubes are the same, and there is no downward slope along the flow direction of the liquid in the tube; due to the temperature and gas-liquid state changes of the liquid in the heat exchange tube from the inlet to the outlet The change in the heat transfer per unit coil area caused by the coil area in different process positions has different requirements for factors such as the flow rate of cooling air, the length of heat exchange tubes, the heat dissipation of cooling water, and the slope of heat exchange tubes. The traditional form of coils cannot meet the above requirements, resulting in a decrease in heat exchange efficiency
