DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

As shown inFIG. 1-6, the present invention provides a preferred embodiment of an electrothermal oil radiator which comprises a radiating body1, an electric-control box2mounted on said radiating body1and a heating body3located inside of said radiating body1, said radiating body1comprises a plurality of radiating fins11connected in turn, each of radiating fin11is hollow and sheet-like and at least two oil leading grooves12are formed inside each of the radiating fin11, hollow connecting sleeves13extending horizontally are formed on upper and lower ends of each radiating fin11, an oil leading hole, in communication with the oil leading grooves12, is formed in each connecting sleeve13, a sealed oil cavity in which heat conducting oil filled is formed by the connecting sleeves13connected together and the oil leading grooves12. As shown inFIG. 11, the heating body3is mounted in the connecting sleeves. A temperature controller24and an overheating protector25are installed inside the electric-control box2which front end is provided with a front panel22, a switch23and a turn button are mounted on the front panel22. The temperature controller24can control the heating temperature, and the overheating protector25can prevent the radiator from overheating. There is a back cover5adapted to be mounted on rear end of the radiator, and a handle51is disposed on the back cover5in order to conveniently move the radiator. A base6is mounted on bottom of the radiator, so as to easily place the radiator.

The connecting sleeves13in accordance with the present invention are also adapted to be mounted on the radiating fin11. Each of the radiating fin11is manufactured by two sheets and has uniform figure and dimension. A reinforcing radiating fin4is mounted between every tow adjacent radiating fins, which distinguishes with the prior art design. The reinforcing radiating fin4may further increase the radiating effect, but without increasing the volume of the electrothermal oil radiator. Therefore, the radiator of the present invention has less dimension than other radiator of the prior art design having same power, and easily to be arranged in house.

As shown inFIG. 7-9, the reinforcing radiating fin4is a single sheet structure, and comprises a radiating plate41and a radiating wall42connected with the radiating plate41. The radiating plate41is not filled with oil and is connected to one side edge of the radiating wall42by a skew plate47. Particularly as shown inFIG. 10, this structure not only ensures the position of the radiating plate41in middle of the width of the radiating wall42, but also allows the reinforcing radiating fin4to be manufactured by punching. Meanwhile, this structure is advantageous for raise of heating air.

As shown inFIG. 8andFIG. 10, the reinforcing radiating fin4is clamped in a connection portion of said connecting sleeves13between the adjacent radiating fins11. Because the heating body3is mounted inside of the connecting sleeves13, the connecting sleeves13obtain the highest temperature, consequently the arrangement of fixing the reinforcing radiating fin4on the connecting sleeve13is not only advantageous for installation, but also reaches a best radiating effect.

As shown inFIGS. 7-10, a protruding ring131formed on one end of a connecting sleeve13is inserted into another end of the adjacent connecting sleeve13through a hole46of the reinforcing radiating fin4. Therefore, said reinforcing radiating fin4is clamped between adjacent connecting sleeves13, easy to install. Each of the connecting sleeve13are hermetically connected together, in installing practice, the protruding ring131is inserted into another end of the adjacent connecting sleeve13, then welding them together, therefore, the reinforcing radiating fin4is tightly fixed between end walls of the adjacent connecting sleeves13.
