A steam radiator generally refers to a heating device that uses steam as a carrier. Generally, a wall-mounted heat exchanger is used, which is divided into a shell-and-tube heat exchanger and a fin-and-tube heat exchanger according to the fluid to be heated. Both are widely used. The latter is generally only used to heat the gas. It can also be widely used in light industry, construction, chemical, machinery, textile, printing and dyeing, electronics, food, medicine, metallurgy coating and other industries in the hot air heating, air conditioning, cooling, condensation, dehumidification, drying and other projects.
The steam radiator type is a heat-dissipating pipe that is suitable for both the steam heating system and the hot water heating system. The inlet and outlet joints are all on the same side, and the inlet and outlet water pipes are connected by U-shaped elbows. Some special requirements on the installation, that is, one end of the heat dissipation pipe must be against the wall or other obstacles. The finned tubes are made of Φ16×lmm copper tubes and wound with 10 × 0.2mm wrinkled copper strips. They are spiral, with 3.2mm-“R”, 4.2mm-“M”, 6.5mm-“T "Three different chip spacings, "R" film spacing, small film spacing and heat dissipation area with maximum heat dissipation; "M" film spacing, large chip spacing, heat dissipation and air resistance are small; "T "The distance between the seeds and the film is the largest. It is suitable for the case where the steam pressure is high and the air temperature rises low.
The steam radiator uses a seamless steel tube (carbon steel, copper or stainless steel) finned tube. The advantage of using a finned tube is that when the heat source or the cold source is in a liquid state, such as steam, water, and heat transfer oil. When heating or cooling with a gas is required, a larger heat exchange area is required. The area of the steam radiator fin tube is several times or even 10 times the area of the ordinary light pipe. At this time, not only the heat exchange efficiency of the equipment is increased, but also the heat exchange cost is greatly reduced.
The steam heat-dissipating pipe has various combinations of different pipe lengths, number of pipes, number of rows and fin pitch, and there are 765 sizes and sizes. After the finned tube is wound, the surface is immersed in a tin-plated tin alloy to ensure that the fins are in close contact with the tube and achieve an aesthetic and anti-corrosion effect. The connection between the finned tube and the inlet and outlet return main pipe is brazed. The other process details are strictly required, and careful consideration is made to ensure that the heat sink has good performance, durability, convenient installation and economical cost.
Steam radiator fin types are: corrugated or flat. 2. The copper tube adopts high-purity seamless copper tube, which has long service life and is not easy to be cracked and corroded. 3. The outer end plate of the coil tube is made of high-quality steel plate with high strength, corrosion resistance and easy assembly. Features: 1. The unique cross-tube method can ensure uniform distribution of the windward area of the entire coil. 2. The fins and copper tubes are mechanically expanded or super-high pressure hydraulic tubes to ensure tight contact and optimal heat transfer. 3. The spacing of the sleeves is large, which reduces the influence of coils in the low temperature system. 4. The internal circuit of the coil is required according to the design flow rate. It adopts single and double reflux systems, with small water resistance and good heat exchange performance. 5. The refrigerant coil is heated by vacuum drying at a high temperature to ensure that there is no impurity in the chamber.
