In fact, industrial radiators are often used in various fields of work, then what is the principle of industrial radiators, many people may not be very clear, and then Xiao Bian will give you about the knowledge of industrial radiators.
What is an industrial radiator
Industrial radiators (abbreviated as heat sinks, also known as heat-dissipating tubes), are the main equipment in the heat exchangers such as cooling air for cooling air, heating air with a heat medium, or recovering air waste heat with cold water. The introduction of high-temperature water, steam or high-temperature heat transfer oil can heat the air, cooling water into the salt water or low-temperature water.
What is the use of industrial radiators?
Industrial radiator can be widely used in light industry, construction, machinery, textile, printing and dyeing, electronics, food, starch, medicine, metallurgy, painting and other industries in the hot air heating, air conditioning, cooling, condensation, dehumidification, drying, etc. .
Industrial radiator structure principle introduction
The structure of an industrial radiator is a heat-dissipating tube, an inlet and outlet manifold, and a frame. Among them, the heat pipe is composed of a heat pipe bundle, and the heat pipe is composed of a base pipe and a fin. The quality of the heat pipe determines the effect of heat transfer. The heat pipe arrangement affects the air resistance. The heat pipe installation method determines the ability to withstand temperature differences (thermal expansion and contraction). Commonly used cooling pipe installation methods: frame fixed (SRZ type, SRL type, S type), frame support type (GL type, U type). Among them, the frame is fixed type, the heat pipe is directly welded to the frame box, the result is simple, generally used for the heat medium or refrigerant below 180°C; the frame is supported, the heat pipe passes through the frame porous plate, and the connecting pipe (or elbow) is welded It is generally used for heat media above 180°C. Common heat pipe types: steel heat pipe (steel pipe around the fins, hot-dip galvanizing), steel-aluminum composite heat pipe (steel pipe rolled aluminum fins), copper heat pipe (copper copper fins around, antimony tin treatment ), copper-aluminum composite heat pipe (copper 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, can fill the gap, stabilize the fins, efficient heat transfer, high-efficiency anti-corrosion; copper heat pipe, antimony tin is the key.
The layout of industrial radiators consists of heat-dissipating tubes, inlet and outlet manifolds, and layout. This is a standardized type of radiator. The standard layout is composed of a steel layout and a heat-dissipating pipe (steel heat pipe). It is produced according to the national specifications. The heat-dissipating pipe adopts the U-shaped elbow connection and the porous plate support, which can eliminate the stress caused by the thermal expansion and other reasons, and has high temperature resistance, good corrosion resistance, and durability. This type of radiator is now widely used in dehumidification, air heating in drying systems, large and medium heating ventilation systems, or air cooling in cooling air conditioning systems.
Industrial Radiator Specifications
Radiating area, ventilation net cross-sectional area, heat transfer coefficient. Among them, the heat dissipation area affects the heat dissipation, which is also the main cost parameter of the radiator; the net cross-sectional area of ​​ventilation affects the ventilation resistance; the heat transfer coefficient affects the heat transfer effect.
Summary: The above is an introduction to industrial radiators and I hope to be helpful to everyone. For more details, please continue to pay attention to this site information.
