열교환기 Flux 면적 계산법

• Header

   cylindrical (condenser) header 가정:

 

- SA (m2) = (2 x 3.14 x R(반경) header(m)) x length of header (m) x 2 headers

   Assuming it is a radiator header

 

- SA (m2) =header length (m) x header width (m) x 2 (sides/header) x 2 (headers)

 

Header

• Tubes

 

-SA(m2) = tube width (m) xtube length (m) x 2 (sides/tube) x total number of tubes

 

 

Tubes

• Fins

 

- Ignore the louvers (방열공) in the fins

 

- SA (m2) = fin width (m) x (fin height (m) x number of fin legs/tube) x 2 (sides/fin) x total number of fins

 

 

Fins

 

= Total Surface area in m2 = SA headers + SA tubes + SA fins
