In order to achieve the above object, the present invention provides a heat dissipation plate and an electric oil heater, which comprises:

a heat sink comprises a main body and an auxiliary body, wherein the edge of the main body extends to one side of the auxiliary body to form an outer edge, and the main body forms a sinking platform at the inner side of the outer edge; vice lamellar body and main lamellar body mirror image setting are established at heavy platform department main lamellar body and vice lamellar body cover to vice lamellar body and main lamellar body butt joint form the sealed chamber that supplies heat-conducting medium to flow.

Further, the main sheet body is provided with the inner edge at the bottom of the sinking platform, the auxiliary sheet body is provided with the edge arranged along the mirror image, and the edge is inserted into the sinking platform along the outer edge and is attached to the inner edge.

Further, the main sheet body and the auxiliary sheet body are welded and fixed.

Furthermore, the outer walls of the main sheet body and the auxiliary sheet body after butt joint are sprayed with paint layers together.

Furthermore, the caliber of the sinking platform is gradually reduced from the outer side to the inner side of the outer edge.

Furthermore, the main piece body expands outwards along the outer edge to form a skirt.

Further, the skirt is protruded to a side close to the sub-sheet body with respect to the sinking platform.

Furthermore, the main sheet body is bent at the edge of the skirt edge to form a flange arranged along the normal direction.

An electric oil heater comprises the radiating fin.

Furthermore, a plurality of radiating fins are arranged, and convex hulls connected with adjacent radiating fins in series are arranged at the upper end and the lower end of each radiating fin.

The utility model discloses a fin and electric oil spit of fland have following advantage:

1) through setting up heavy platform, solved the not enough problem of fin stress structural strength, prevent to appear after the assembly that the clearance is big and uneven problem, simultaneously because the location is accurate, fault and crack are difficult to appear in the fin spraying.

2) The whole processing technology is simple, the production and the assembly are easy to position, and the production and the assembly efficiency are improved; and meanwhile, the appearance grade and the user experience of the product are also improved.

Detailed Description

In order to better understand the purpose, structure and function of the present invention, the following description will be made in detail with reference to the accompanying drawings.

As shown in FIG. 1, the electric oil-filled radiator of the present invention comprises a plurality of heat dissipation fins. Convex hulls 5 connected with adjacent radiating fins in series are arranged at the upper end and the lower end of each radiating fin, and oil passages are arranged in the radiating fins. When the power supply is connected, the heat conducting oil around the electric heating tube is heated, and then the heat conducting oil serving as a heat conducting medium circulates among the radiating fins along the oil way to radiate heat.

Referring to fig. 2, the heat sink includes a main body 1 and a sub-body 2, an outer edge 11 is formed by extending the edge of the main body 1 to one side of the sub-body 2, and a sinking platform 3 is formed on the inner side of the outer edge 11 of the main body 1; vice lamellar body 2 sets up with main lamellar body 1 mirror image, establishes in 3 places of heavy platform main lamellar body 1 and vice lamellar body 2 covers to vice lamellar body 2 and main lamellar body 1 butt joint form supply heat-conducting medium mobile seal chamber 4.

The main sheet body 1 is provided with an inner edge 12 at the bottom of the sinking platform 3, the auxiliary sheet body 2 is provided with an edge 21 arranged in a mirror image with the inner edge 12, and the edge 21 is inserted into the sinking platform 3 along the outer edge 11 and is attached to the inner edge 12. Thereby through setting up 3 structures of heavy platform, main lamellar body 1 and the 2 clearances of vice lamellar body are less, and the assembly can be directly spacing, does benefit to main lamellar body 1 and the welding of vice lamellar body 2, has improved fin production welding efficiency.

Main lamellar body 1 and the 2 outer walls of vice lamellar body after the butt joint have the paint layer of spraying jointly, moreover because cooperation position between them is located heavy platform 3, the less clearance of cooperation position can be covered by paint, and broken line or fault problem after the spraying can not appear in the outward appearance, has thoroughly solved fin spraying outward appearance problem. Meanwhile, the problems of positioning dislocation and welding dislocation of the main sheet body 1 and the auxiliary sheet body 2 are solved, and the attractiveness of the product is guaranteed.

In order to facilitate the insertion of the sub-sheet body 2, the caliber of the sinking platform 3 is gradually reduced from the outer side to the inner side of the outer edge 11.

Main lamellar body 1 expands to the outside along outer edge 11 edge and is formed with shirt rim 13, and shirt rim 13 is for sinking platform 3 to being close to vice lamellar body 2 one side protrusion, and the area of contact of increase main lamellar body 1 and air guarantees the radiating effect of main lamellar body 1.

Main lamellar body 1 is formed with along the turn-ups 14 of normal direction setting at 13 marginal bendings of shirt rim, strengthens main lamellar body 1's intensity, and vice lamellar body 2 lock is in heavy platform 3 simultaneously to make whole fin have better intensity.

It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes or equivalents may be substituted for elements thereof by those skilled in the art without departing from the spirit and scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof.
