How to calculate the heat transfer area of the finned tube?
- Jan 24, 2018 -

1. how to calculate the heat transfer area of the finned tube?

The formula for calculating the heat transfer area of the finned tube is the effective surface area of the base tube plus the whole surface area of the fin.

2. What are the common materials of the finned tube?

The commonly used material of the finned tube usually includes copper, aluminum, steel and cast iron.

3.What are the requirements for the processing of the fin type heat exchanger used in the Freon refrigerating unit?

The processing requirements for the fin type heat exchanger used in the freon refrigeration unit are mainly:

(1) if the heat transfer tube is a flat tube, then there can be no rupture at the edge of the tube.

(2) its end plate should be smooth and can not have the phenomenon of warping or skewing.

(3) the spacing between the fins should be uniform, and the contact between the fins should be tightened. After the mechanical expansion of the tube, there should be no scratches on the inner wall.

(4) the surface of the fin heat exchanger should be treated as a necessary antirust treatment.
