Radiator is the main equipment for winter heating in our modern home, and finned tube radiator is the most widely used type of heat transfer equipment in gas and liquid heat exchanger. It achieves the purpose of enhanced heat transfer by adding fins to the common base tube. Here we will introduce: the use of finned tube radiator and the standard.
Finned tube radiator structural principle
Where the heat exchanger tube is equipped with fins to increase the area of heat dissipation of the cold heat exchanger, can be summarized as "finned tube radiator".
Finned tube radiator according to the structure of the fins can be divided into winding type, string type, welding type, rolling type. Commonly used materials are steel, stainless steel, copper, aluminum and so on.
Use of finned radiator
The most widely used finned radiator is the steel and aluminum finned tube (winding type steel-aluminum composite finned tube, rolled type steel-aluminum composite finned tube), which makes use of the pressure-resistant steel tubes and aluminum's efficient thermal conductivity, and is compounded on a special machine tool. Its contact thermal resistance is almost zero under the working condition of 210℃.
Finned tube radiator is generally used for heating or cooling air, has a compact structure,
large unit heat exchange area and so on. It is widely used in textile, printing and dyeing, petroleum, chemical, drying, electric power and other fields.Finned tube radiator price
Finned condenser evaporator radiator ￥188.00.
Air-cooled 60-module finned heat exchanger radiator ￥2500.00.
Finned tube radiator specifications
Finned tube radiator specifications: 4 minutes 6 minutes 1 inch, inch and a half, two inches, two and a half inches, three inches, 4 inch, etc., can also be customized.
Finned tube radiator standard
According to the wall thickness standard: civil building energy-saving design (using the residential building part) JGJ25-95 standard clearly stipulates that the industry standard for household finned tube radiator requires a wall thickness of 15mm plus or minus the lower difference of 0.05mm. mm, another for the special requirements of the wall thickness of 1.5mm or more. Finned tube radiator wall thickness is a decisive factor in determining the service life of household finned tube radiators, but is by no means the only factor.
According to the internal anticorrosion coating standards: the same civil building energy-saving design (using the residential building part) JGJ25-95 standard clearly stipulates that the internal anticorrosive coating of household finned-tube radiators must be used in the 6-step process such as acid selection - phosphating - passivation - neutralization - surface conditioning, and so on, and the current internal treatment of finned-tube radiators in the industry in the 4-8 step process.
