1. Thermal performance requirements finned radiator heat transfer coefficient K higher the value, the better description of its thermal performance. Improve the heat dissipation of the radiator, radiator fins increase the heat transfer coefficient method that can be used to increase the area of ??the outer wall of the cooling fins to improve air flow around the radiator to increase the speed and intensity of other ways to radiate heat sink. 2. Economic requirements, finned radiator is a unit of heat required to pass the room, the less metal consumption, lower cost, and its economy is better. Metal finned radiator heat intensity is a measure of a sign radiator economy. Metal heat intensity is defined as the average medium heat sink temperature and the indoor air temperature difference of 1 ℃ time. Per kilogram quality radiator heat generated per unit time. 3. Installation and process requirements finned radiator should have a certain mechanical strength and bearing capacity; structure should be easy to mix into the desired area of ??the air heating coil cooling radiator, structure size to small, accounting for less room area and space drying equipment radiators, finned radiator production process should meet the requirements of mass production. 4. Health and aesthetic requirements, smooth appearance finned tube radiators Which is good, not fouling and easy to clean, finned radiator installation should not affect the perception of the room. 5. Requirements of life, finned radiator corrosion and should not be easily broken, long service life. Finned radiator is currently the most widely used steel and aluminum finned tube (around the chip composite steel-aluminum finned tubes, Rolled Steel Aluminium composite fin tube) which uses a pressure-resistant steel and aluminum Efficient thermal performance of the radiator, on a dedicated machine composite. Contact resistance under working conditions, 210 ℃ almost zero. Aluminium composite pipe radiator having other types of finned tube radiators irreplaceable advantages. Finned tube radiators are generally used for heating or cooling air, with a compact structure, large unit heat transfer area and so on. Widely used in various fields such as textile, printing and dyeing, petroleum, chemical, dry, and electric power. Where the installation of the fin tubes to achieve the increase in the cooling area of ??the cold heat exchanger, can be summed up as "finned tube radiators." Finned tube heat sink fins in the form structure can be divided into slices around; string piece; lug type; Rolled. Commonly used materials for steel; stainless steel; copper; aluminum.
