Aluminum fin tube radiator structure

2021-08-11
Industrial radiators (abbreviated as radiators, also known as radiator pipes) are the main equipment in heat exchange devices, such as cooling air with refrigerant, heating air with heat medium, or recovering air waste heat with cold water. Pass in high temperature water, steam or high temperature heat transfer oil to heat the air, pass in salt water or low temperature water to cool the air. Industrial radiators can be widely used in light industry, construction, machinery, textiles, printing and dyeing, electronics, food, starch, medicine, metallurgy, coating and other industries in hot air heating, air conditioning, cooling, condensation, dehumidification, drying, etc. .

The structural features of this equipment are: (1) The inner and outer channels of the tube are both finned tube-type involute hydrodynamic channels, which can maintain the opposite direction and rotational fluidity of the primary medium and the secondary medium for heat transfer. Compared with the finned tube plate heat exchanger, this product has high heat exchange efficiency, low raw material consumption, compact structure, light weight, lighter weight, and high pressure capacity. Because it does not require the length of the riser, the total heat exchange is The area is greatly increased and the wall thickness is thinner. (2) It is suitable for the situation where the pressure difference between the two safety channels is very large. Because of the high pressure bearing capacity of the finned tube magnetic ring, the high pressure medium is introduced into the tube, and the bottom pressure medium is introduced outside the tube. (3) The machine equipment changes the spacing column in the finned tube sheet into a spacing piece, which saves raw materials and has a stronger actual effect of heat conduction.

Item 1. One-way heating or cooling
1. The name, temperature and pressure of the heat source or cold source;
2. Air volume, inlet temperature, required outlet temperature;
3. Air inlet pressure, allowable pressure loss after air passes through the radiator;

4. Others.


Item 2: Circulating heating or cooling (such as drying room)
1. The name, temperature and pressure of the heat source or cold source;
2. Drying room size, heat preservation measures, name of the material to be dried, moisture content, drying weight per hour, material conveying form;
3. Setting the temperature that the air in the drying room needs to maintain, and the time for the initial heating of the drying room to reach the required temperature;

4. Air circulation volume, pressure, drying room moisture volume, internal circulation or external circulation, and whether the circulation point is single point or multiple points;
