Description

Technical Field

[0001] The utility model belongs to the technical field of valve cover heat dissipation, in particular to a valve cover with an inlaid heat dissipation type. Background Art

[0002] There are two types of existing high-temperature valve heat dissipation bonnets. One type is a fin type with heat sinks arranged parallel to the center axis of the bonnet. This type is usually 4 fins symmetrically distributed and is mostly a casting structure. However, this structure has a small heat dissipation area per fin, so the heat dissipation effect is relatively poor.

[0003] The other is a vertical valve cover center axis, with a ring sleeve on the valve cover middle neck. Due to the difficulty in casting and the easy occurrence of defects, most of them are welded structures. This welding structure can increase the heat dissipation area, but because the existing heat sink needs to be welded on the middle neck, it is difficult to process, and there is a large gap between the multiple heat sinks and the middle neck, which is not conducive to heat conduction and heat dissipation. Moreover, there is no reference positioning during welding, and the spacing and relative parallelism of the heat sinks are inconsistent, affecting the appearance. At the same time, welding is performed at the bottom of the connection between the heat sink and the valve cover, which is difficult to weld and has low operating efficiency. Therefore, it is urgently necessary to design a valve cover with an inlaid heat dissipation to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a valve cover with an inlaid heat dissipation type, which solves the problem that the heat dissipation area of ​​the heat dissipation mechanism proposed above is small, resulting in poor heat dissipation effect, the problem that the spacing distance and parallelism cannot be controlled due to the lack of reference for the heat sink welding, and the problem that the existing heat sink connection and welding methods cannot stabilize the heat sink.

[0006] Furthermore, a groove depth of the positioning groove is greater than one times the thickness of the embedded portion, and is less than or equal to twice the thickness of the embedded portion.

[0007] Furthermore, the width of the positioning groove is equal to the thickness of the embedding portion.

[0008] Furthermore, the heat dissipation mechanism includes the positioning groove and a pair of heat sinks, the positioning groove is an annular groove, the pair of heat sinks are arranged opposite to each other, and the embedded parts of the pair of heat sinks are respectively inserted into the positioning groove.

[0009] Furthermore, a pair of the heat sinks are arranged opposite to each other and together form a heat sink ring, and the inner ring side surface of the heat sink ring is in contact with the bottom surface of the ring groove.

[0010] Furthermore, the sheet body and the embedded portion are integrally formed to form the heat sink.

[0011] Furthermore, the embedded parts of a pair of the heat sinks are respectively embedded in the positioning grooves of the valve cover body, the opposite sides of the pair of heat sinks are abutted, and the abutting parts of the pair of heat sinks are fixed by welding to fix the pair of heat sinks on the valve cover body.

[0012] Furthermore, there are at least two welding points, and the welding points are both located at the outer edges of a pair of heat sinks.

[0013] Furthermore, the outer contour of the heat dissipation ring sheet is circular.

[0014] Furthermore, the valve cover body includes a base, a middle neck and a flange plate which are arranged in sequence from bottom to top, and the base, the middle neck and the flange plate are an integrally formed structure.

The width of the positioning groove 21 is equal to the thickness of the embedded portion 222. The size of the positioning groove 21 is set to effectively improve the tightness of the fit between the embedded portion 222 and the positioning groove 21, so as to improve the heat conduction and heat dissipation function of the heat dissipation mechanism 2, and solve the problem of poor heat dissipation performance caused by a large gap between the existing heat sink and the middle neck. Preferably, the depth of the positioning groove 21 is equal to twice the thickness of the embedded portion 222.

[0027] The heat dissipation mechanism 2 includes a positioning groove 21 and a pair of heat sinks 22. The positioning groove 21 is an annular groove. The pair of heat sinks 22 are arranged opposite to each other, and the embedded parts 222 of the pair of heat sinks 22 are respectively inserted into the positioning groove 21. The pair of heat sinks 22 are arranged opposite to each other and together form a heat sink ring. The outer contour of the heat sink ring is circular, and the inner ring side surface of the heat sink ring is a cylindrical surface that fits the bottom surface of the annular groove.

[0028] The embedding portions 222 of a pair of heat sinks 22 are respectively embedded in the positioning grooves 21 of the valve cover body 1 , and the opposite sides of the pair of heat sinks 22 abut against each other.
