The fin-type heat sink is currently the most widely used steel-aluminum finned tube (coiled steel-aluminum composite finned tube, rolled steel-aluminum composite finned tube). It utilizes the pressure resistance of the steel tube and aluminum. High-efficiency thermal conductivity is compounded on dedicated machine tools. Its contact thermal resistance is almost zero at 210°C. Everybody may be a little strange to this standard for household finned tube radiators, but don't worry. Today I took this opportunity to explain to you the standards of domestic finned tube radiators , friends for the majority of people in need, and friends in the future. We provide a platform to let you know the specifics of the standard for household finned tube radiators . Finned Tube Radiator Finned tube radiators are the most widely used heat exchange equipment in gas and liquid heat exchangers. It achieves the purpose of enhancing heat transfer by adding fins to a common base pipe. Base pipe can use steel pipe; stainless steel pipe; copper pipe and so on. The fins can also be used with steel strips; stainless steel strips, copper strips, aluminum strips, etc. Finned tube radiator works The principle of a finned tube radiator is to cool the air with a refrigerant, or heat the air with a heat medium, or recover the residual heat of the air with cold water. The main equipment in the heat exchange device, such as high temperature water, steam or high temperature heat transfer oil, can heat the air. Into the brine or low-temperature water to cool the air. Fin tube radiator type If divided according to the structure of the fins, finned tube heat sinks can be divided into the following types: coil-type, string-type, solder-type and roll-type. Finned tube radiator specifications Finned tube radiator specifications are: 4 points 6 points 1 inch, inch half, two inches, two and a half inches, three inches, 4 inches, etc., can also be customized. Finned tube radiator use The fin-type heat sink is currently the most widely used steel-aluminum finned tube (coiled steel-aluminum composite finned tube, rolled steel-aluminum composite finned tube). It utilizes the pressure resistance of the steel tube and aluminum. The efficient thermal conductivity is compounded on a dedicated machine tool and its contact thermal resistance is virtually zero at 210°C. The finned tube radiator is generally used to heat or cool air, has a compact structure, a large unit heat transfer area and other characteristics, widely used in textile, printing and dyeing, petroleum, chemical, drying, electricity and other fields. Finned tube radiator standard 1. According to the standard of wall thickness: The energy-saving design of civil buildings adopts the residential building part, and the standard of JGJ25-95 clearly stipulates that the industry standard for household finned tube radiators requires a wall thickness of 15mm plus or minus 0.05mm, which is currently available on the market. There are three kinds of wall thickness, one is the ultra-thin 1.0mm, one is the national standard 1.5mm, and the other one is the special requirements of the wall thickness of more than 1.5mm, the fin tube radiator wall thickness is determined that the household finned tube radiator The decisive factor in service life, but by no means the only factor. 2, according to the internal anti-corrosion coating standard: the same civil building energy-efficient design using residential building part, JGJ25-95 standard clearly stipulates that domestic finned tube radiator internal anti-corrosion coating must use acid selection - "phosphorus - Passivation - "and" - "table tones and other six-step process, the current internal treatment of the fin tube radiator industry are in 4-8 steps. 3, according to spray technology standards: The spraying technology of domestic finned tube radiator is relatively strict. The heating surface of the household heating is exposed in the air and is prone to oxidation. The fin tube radiator spraying technology is not strict, and it easily causes the surface of the finned tube radiator to oxidize, forming a yellow water stain. Fin tube radiator purchase considerations 1. Whether the working pressure of the radiator can meet the working pressure of the system and whether it meets the requirements of the product standard. 2. If it is used in civil buildings, then you should choose a finned tube radiator that is beautiful in appearance and easy to clean. If it is used in industrial buildings and the dustproof requirements are relatively high, you should choose the fins that can be easily cleaned. Tube radiator. 3. In industrial buildings containing corrosive gases or in environments with relatively high relative humidity, finned tube radiators with corrosion resistance should be used. 4, steel finned tube radiator, it should adopt a closed system, and to meet the water quality requirements. 5, aluminum finned tube radiator, should be internal anti-corrosion type, and to meet the water quality requirements. 6, should choose the formal manufacturer, so that in the quality, after-sales service and other aspects can be guaranteed. Editor's summary: If everyone is choosing a household finned tube radiator, but the standards for household finned tube radiators are unclear, this article can be very helpful in helping everyone understand the standard of household finned tube radiators and eliminate them. Problems in the selection, avoid unnecessary trouble.
