Air-Cooling Effects of Fins on a Motorcycle Engine : 5th Report, Effects of Baffle Plate Installed between the Fins

Abstract

An air coded engine with a firmed cylinder may have reeidiial heat between the fins. In oader to rediioe the residiid heat, the baffle plates were installed between the fins. The teinperature in the cylinder and on the surface of the fins was measured at various air speeds in the wind tunnel The eflects of positions of the baffle plate to the cylinder on fin temperature were examined. Results indicated that when the position of the baffle plate was set so that it was easy for the air to flow between the fins, the heat transfer from the fin was higher and the fin temperature was more uniform in circumference.
