Finned radiator is a gas and a liquid heat exchanger, the most widely used kind of heat transfer equipment. It is through the installation of the fins on the general purpose of the base tube to achieve enhanced heat transfer. Based steel pipe can be used; stainless steel tube; brass and so on. Fins can also use steel; stainless steel, copper, aluminum and so on. Finned radiator fin structure can be divided into chip form around; string-piece; lug type; Rolled. Is currently the most widely used steel and aluminum composite fin tube, which uses the pressure resistance and thermal conductivity of aluminum, steel and efficient performance of soda mixed heater, composite made on a dedicated machine. Contact resistance under working conditions, 210 ℃ almost zero. Aluminium composite pipe has another class finned tube radiators irreplaceable advantages. Flow and Heat Transfer in the radiator features: (1) when the three-hole probe measurements of flow field radiator airflow passing between two fins, study the flow characteristics of the radiator; (2) study the local heat sink case Under the heat transfer characteristics; and (3) to establish a three-dimensional flow and heat sink calculation model wind heater, the test conditions were simulated; (4) comparing the effects of intake mode radiator heat transfer performance ; (5) compared the effects of the heat sink fins in the form of flow and heat transfer characteristics; (6) to establish a model for optimal design of the radiator heater, radiator optimized design. The test results are given between the two radiator fins flow field velocity vector, observed around the flow of gas to flow through the radiator when the phenomenon, and to verify the situation of local heat flux and average heat flow is a big difference. srl heater, air conditioner Watson (certified), provided by the Texas Watson heater air-conditioning plant.
