1. Thermal performance requirements finned radiator heat transfer coefficient K higher the value, the better description of its thermal performance. Increase the amount of heat sink, increasing the heat transfer coefficient of the finned radiator heater method can be used to increase the outer wall of the finned radiator cooling area to improve the speed and increase the flow of air around the radiator radiates strength and other means. 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 required cooling area, structure size smaller srz heaters, room size and occupy less space, wings piece radiator production process should meet the requirements of mass production. 4. Health and aesthetic requirements of wind heaters, smooth appearance, 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. SRL-type radiator total of 37 kinds of specifications, the radiator is the application bundle composed of steel aluminum fins. So close contact with aluminum and steel duct good electric heaters, thermal performance, use and reliable. SRL-type radiator with steam or hot water as heat medium, steam pressure up to 16Kg / cm2, temperature of warm water over 130 ° C, applied to an air conditioning system and the air in the drying chamber is heated. SRL-type radiator points along the flow direction in the second row of tubes and pipes are arranged in three rows, the models for example as follows: SRL-5 * 5 / 2-- airflow direction along two rows of staggered tube. SRL-5 * 5 / 3-- along the direction of airflow in three rows of staggered tube. Heater air heater _ _ Watson Watson air conditioning provided by the Texas air-conditioning plant.
