Title: Finned tube
Inventor: KURUSU SHINGO
IPC: F28F1/32
Filed: 1980-05-22
Abstract: PURPOSE: To raise the coefft. of the heat transfer in the rear portion of fins by attaching resistors to the fins in such a way as to enable the fluid outside a pipe to flow along the rear portion of the fins while going round the pipe.  
     CONSTITUTION: Fins 2 are wholly attached to a core pipe 1 provided at a right angle to the main flows 5 of a fluid outside a pipe to make up a finned tube 3. Then, a thin plate 4 is provided by welding, etc., to the peripheral edge of the fins 2 situated at the position of 45° to the main flow 5 of the fluid outside the pipe on the back flow side of the fins 2. When the main flow 5 passes by, the thin plate 4 serves as a resistor against the main flow 5 of the fluid outside the pipe, and the air flow which passes through the fin 2a on the frontal side of the core pipe 1 is changed its direction by the thin plate 4 to enable it to pass through the fin 2b on the back side of the core pipe 1. Thus, the thermal transmission property on the back side of the core pipe 1 can be increased up to the same level as that on the fin 2a on the frontal side of the core pipe 1, whereby increasing the average coefft. of  the heat transfer on the fin 2a.
