Description

Cooling tower with spiral packing structure

Technical Field

The utility model relates to the field of mechanical equipment, specific cooling tower with spiral filler structure that says so.

Background

The cooling tower is a device which uses water as a circulating coolant, absorbs heat from a system and discharges the heat to the atmosphere so as to reduce the water temperature, and the working principle is that the water is in flowing contact with air and then carries out heat exchange to generate steam, and the steam volatilizes and takes away the heat, thereby achieving the purpose of evaporation and heat dissipation.

Research shows that the main reason influencing the heat dissipation of the cooling tower is that the air resistance is large, and the air which has already exchanged heat with water cannot be discharged to equipment in time, so that the heat exchange efficiency is low.

The reason for this phenomenon is that the heat dissipation of the cooling tower depends on air to take away the heat, and water passes through the gaps of the filler in the process of passing through the filler, and the purpose of passing through the filler is to disperse the water flow so as to achieve the purpose of fully contacting with the air, so the smaller the gap processing of the filler is, the more the heat exchange between the water and the air is facilitated, but the air also passes through the gaps of the filler, the larger the gap processing of the filler is, the more the air flows, and thus the two phenomena are contradictory,

the traditional coping method is to increase the power of a heat exchange fan at the top of the cooling tower, the effect brought by the method is not obvious, the power consumption of equipment is increased unnecessarily, and the flow of air in the tower body is not improved obviously.
