(1) The inner and outer channels of the tube are both finned tube-type involute hydrodynamic channels, which can maintain the reverse direction and rotational fluidity of the primary and secondary media 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.
Finned tube heat exchangers are currently widely used in steel-aluminum finned tubes (winding finned steel-aluminum composite finned tubes, rolled finned steel-aluminum composite finned tubes), which take advantage of the pressure resistance of steel pipes and the strength of aluminum. Efficient thermal conductivity, compounded on a dedicated machine tool. Its contact resistance is almost zero at 210°C. Finned tube heat exchangers are generally used to heat or cool air, and have the characteristics of compact structure and large lamps per unit heating area. It is widely used in textile, printing and dyeing, petroleum, chemical industry, drying, electric power and other fields.
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.
