The present invention relates to a radiation fin with a bent radiating portion including a main body having a groove for introducing oil formed therein and connection sleeves horizontally extending from both ends of upper and lower ends thereof, and an electrical oil heater using the same. The main body includes a bent radiation portion formed in an area from an edge of one end thereof to a center portion. Both the upper and lower ends of the bent radiation portion are positioned in different vertical planes or in the vertical plane, but at least one portion of the center of the upper and lower ends is curved and protrudes from a side of the main body. The radiation fin with a bent radiation portion of the present invention has an advantage over the conventional art. The radiation fin with a bent radiation portion can perform a radiation method in which a radiation and convection are combined when a plurality of radiation fins are connected and can improve radiation of a radiation object in horizontal and vertical directions by including bent radiation fins in a predetermined area from an edge of one end of the radiation fin to the center. |
