Abstract: A radiating fin with a bent radiating portion and an electrothermal oil heater using the same are provided. The radiating fin comprises a main body with an oil guide groove formed therein, connecting sleeves extending in a horizontal direction being provided at an upper end and a lower end of the main body; a bent radiating portion is formed within a region, a certain distance away from the middle, of an edge of at least one end of the main body; and an upper end and a lower end of the bent radiating portion are located in different vertical planes, or the upper end and the lower end of the bent radiating portion are located in a same vertical plane, and at least one portion between the upper end and the lower end is bent to form a side-raised structure.

Abstract: Disclosed are various thermoelectric heaters. A thermal transfer component has a first plate attached to a second plate. A heating channel is formed by at least one of the first plate or the second plate of the thermal transfer component. The heating channel is between the first plate and the second plate of the thermal transfer component. A heating element is within the heating channel.

Abstract: An electrothermal oil radiator includes a radiating body (1), an electric-control box (2) mounted on the radiating body (1) and a heating body (3) located inside the radiating body (1). The radiating body (1) includes a plurality of radiating fins (11) linked in turn. Each radiating fin (11) is hollow and sheet-like and has at least two oil leading grooves (12) inside thereof. Hollow connecting sleeves (13) extending horizontally are formed or mounted on upper and lower ends of each radiating fin (11). An oil leading hole in communication with the oil leading grooves (12) is formed in each connecting sleeve (13). The sleeves (13) on each radiating fin (11) are connected together to form a sealed oil cavity in which heat conducting oil is filled. A reinforcing radiating fin (4) is mounted between two adjacent radiating fins (11).

Abstract: An improved electric radiator filled with oil includes a plurality of radiating fins, an electric-control box and a heater. Within the electric-control box, a switch, a temperature controller, a heat protector and a wire are provided. The radiating fin is hollow and sheet-like with at least two grooves therein for leading oil. The upper and lower ends of the fins are provided with hollow connecting-sleeves, oil-inflow holes are formed inside the connecting-sleeves. Each of the radiating fins is communicated with the oil-inflow hole and is filled with oil. Either the upper and the lower ends of each radiating fin are in different vertical planes, or the upper and the lower ends of each radiating fin are in a same vertical plane, but at least a part of the middle of each radiating fin is curved to form a convex configuration towards the side. Each of the radiating fins has the same shape and dimensions.
