Customized Heating Element Oven Finned Tubular Heater

Short Description:

Finned tubular heaters are used to improve the heat exchange efficiency. They are usually used to increase the external surface area (or internal surface area) of the heat exchange by adding fins on the surface of the heat exchange tube in order to achieve the purpose of improving the heat exchange efficiency. It is the most widely used heat exchanger in gasliquid heat exchangers, which enhances heat transfer by adding fins on the ordinary base tube.

Performance characteristics

Fin tubular heaters have many excellent properties, including anti-corrosion performance, wear resistance, low contact thermal resistance and anti-dust performance. Anti-corrosion performance is achieved by spraying anti-corrosion liquid on the inner wall of the raw material and treating the outer wall with anti-rust paint, silver powder or hot-dip galvanizing. Wear resistance is due to its thick wall thickness (usually more than 3.5mm). Low contact thermal resistance is achieved by increasing the contact area with air by spiral processing. Excellent anti-dust performance and easy to clean.

Working Principle

Finned tubular heaters increase the outer or inner surface area of the heat exchange tube by adding fins to the surface of the heat exchange tube, thereby improving the heat exchange efficiency. This design not only improves the heat transfer efficiency, but also increases the heat dissipation area. Finned tubes are easy to install, reduce the number of connection points, reduce the chance of water leakage, are easy to maintain, and have a long service life.

Product use instructions

★Do not in outdoor environments with high humidity.

★When the dry burning electric heating tube heats the air, the components should be arranged evenly and crisscrossed to ensure that components have good heat dissipation conditions and that the air passing through can be fully heated.

★The default material for stock items is stainless steel 201, the recommended operating temperature is <250°C. Other temperatures and materials can be customized, with stainless steel 304 selected for temperatures below 00°C and stainless steel 310S selected for temperatures below 800°C.

Application fields

Heating and cooling equipment: It is widely used in equipment such as hot air furnaces, radiators, and air conditioners. Inators and air conditioners, it can quickly dissipate the heat inside the equipment, ensuring the normal operation of the equipment.

Industrial field: It is also widely used petrochemical, electric power, metallurgical and other fields, such as heat recovery of economizer, air preheater and waste heat boiler.

Drying and ventilation system: SRQ finned tube radiator is composed of steel porous plate frame and steel finned tube radiator, which is widely used in air heating of drying system and heating ventilation exchange system of large and medium sized.
