Structural principle of engineering radiator

- Mar 09, 2020-

Engineering radiator can be widely used in light industry, construction, machinery, electronics, metallurgy and other industries to play the role of hot air heating, air conditioning, cooling, dehumidification, which is closely related to its structural principles.

The structure of the industrial radiator is composed of a heat dissipation pipe, an inlet and outlet manifold, and a frame.
Among them, the heat radiation pipe is composed of a heat radiation tube bundle, and the heat radiation tube is composed of a base pipe and a fin. The quality of the heat pipe determines the heat exchange effect, the way the heat pipe is arranged affects the air resistance, and the way the heat pipe is installed determines the ability to withstand temperature differences (thermal expansion and contraction).

Common cooling pipe installation methods: fixed frame (SRZ, SRL, S), frame support (GL, U).
Among them, the frame is fixed, and the heat pipe is directly welded to the frame box. The result is simple, and it is generally used for heat or refrigerant below 180 ° C. The frame is supported, the heat pipe passes through the frame perforated plate and is welded to the connecting pipe (or elbow). , Generally used for heat medium above 180 ℃.

Common types of heat pipes: steel heat pipes (steel pipe around steel fins, hot-dip galvanized), steel and aluminum composite heat pipes (pipe rolled aluminum fins), copper heat pipes (copper pipes around copper fins, tinned ), Copper-aluminum compound heat pipe (copper pipe rolled aluminum fins), stainless steel heat pipe (stainless steel pipe around stainless steel fins, high frequency welding).
Among them, the steel heat pipe, hot-dip galvanizing is the key, which can fill the gap, stabilize the fins, efficient heat transfer, and efficient anticorrosion; the copper heat pipe, tin lining is the key.

Different structures create different specifications and models of industrial radiators, which can be widely used in multiple industrial fields and give full play to the use of effects.
