Finned tube structure of the radiator ZGL 1. ZGL finned tube radiator with steel double loop (second row), or loops (four-row, six-row) structure, cold rolled steel and aluminum finned tube with composite molding process, the substrate tube Ф18 * 2mm, chip high 10mm, slice thickness 0.3mm, films from 3mm, high pressure, corrosion resistance; 2. Fin-tube heat exchanger exhaust pipe full staggered arrangement, and with a separate pipe connecting elbow; 3. Good Radiator ZGL finned tube heat exchange performance, can replace the use of steel pipe radiator fins; 4. Heat pipe Features: cooling area: 0.64m2 / m rib coefficient: 14.56 rib pass coefficients: 15.8 net surface ratio: 0.53 air heat sink fan start before I prepare an air radiator when steam is used as heating medium, before ten minutes before steaming, preheating radiator, avoid sudden steam into the cold radiator and produce large amounts of condensate, the impact of equipment; 2, the radiator air inlet pipe directly connected with the outdoor, should It is provided at the inlet of the occlusion device to prevent the radiator to stop working when were frozen; 3, before indoor installation should look to take over the side for the inlet end of the finned tube shrinkage; 4, should return to take over the terminal installation trap, trap displacement should not exceed 3 to 4 times cooler condensate water; 5, the air cooler to be equipped with the appropriate heat medium pipe system according to architectural design. Note steam or hot water piping and the water on the road should return valve means; with steam heating, condensation water on the road for a device condensate removal device. Inside the radiator flow and heat transfer characteristics: (1) when the three-hole probe measurements of flow field radiator airflow passing between two fins, study flow characteristics of the radiator; (2) The heat sink in the local situation Heat Transfer Characteristics; and (3) to establish a three-dimensional model of flow and heat sink, the test conditions were simulated; (4) compared the effects of Inlet radiator heat transfer performance; and (5 ) compared the effects of the heat sink fins in the form of flow and heat transfer characteristics; (6) to establish optimal design model of the radiator, radiator was optimized. The test results are given between two fin radiator flow field velocity vector, observed the phenomenon of gas flow through the flow around the radiator when verify the situation of local heat flux and average heat flow is very different.
