The utility model adopts the technical proposal that: the utility model provides a heat dissipation type toper gasket, includes the toper gasket body, toper gasket body middle part be equipped with the through-hole that supplies the bolt to pass, the hammer-shaped lateral wall of toper gasket body on be equipped with the radiating groove, be equipped with the louvre that communicates to the through-hole in the radiating groove, follow the fin has been arranged to the bottom outer lane circumference of toper gasket body, evenly arranged on the up end of toper gasket body and the lower terminal surface hemisphere arch.

Furthermore, the radiating fin is of a T-shaped structure.

Furthermore, the bottom of the through hole of the tapered gasket body is inwardly contracted, so that the thickness of the upper end face of the tapered gasket body is smaller than that of the lower end face.

Furthermore, a heat dissipation layer is compounded on the outer surface of the conical gasket body through a compounding process.

Furthermore, the heat dissipation layer is a polyimide layer, and the thickness of the polyimide layer is 0.1-0.3 mm.

Furthermore, the number of the hemispherical bulges is at least 4, and the hemispherical bulges are circumferentially arranged along the upper end surface or the lower end surface of the conical gasket body.

The utility model has the advantages that: the utility model discloses a set up louvre and fin, make the gasket have fine heat-sinking capability, can be applicable to in the radiating environment of needs, improve the application scope of gasket, have simple structure, low cost's advantage.

In addition to the objects, features and advantages described above, other objects, features and advantages of the present invention are also provided.

The present invention will be described in further detail below with reference to the drawings.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic cross-sectional view of the present invention.

In the figure: 1. a tapered gasket body; 2. a through hole; 3. a heat sink; 4. heat dissipation holes; 5. a heat sink; 6. a hemispherical protrusion; 7. and a heat dissipation layer.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.

The utility model provides a heat dissipation type toper gasket.

In this embodiment, referring to fig. 1 and 2, the heat dissipation type conical gasket includes a conical gasket body 1, a through hole 2 for a bolt to pass through is formed in the middle of the conical gasket body 1, a heat dissipation groove 3 is formed in a hammer-shaped side wall of the conical gasket body 1, a heat dissipation hole 4 communicated with the through hole is formed in the heat dissipation groove 3, and a gap (as shown in fig. 2) is reserved between the bottom of the through hole of the conical gasket and a screw due to the characteristic of the conical gasket, so that the heat dissipation hole communicated with the through hole is formed in the conical side wall of the conical gasket body, and therefore, the inner space and the outer space of the conical gasket are communicated, and compared with a common gasket, the heat dissipation capability of the conical gasket is obviously;

radiating fins 5 are arranged along the circumference of the outer ring at the bottom of the conical gasket body 1, and hemispherical protrusions 6 are uniformly arranged on the upper end face and the lower end face of the conical gasket body. Wherein the setting of fin, further improvement the heat-sinking capability of conical pad, the protruding compressive wear resistance who mainly is used the gasket of hemisphere of the up end of conical pad body, and service life is prolonged, the hemisphere of the lower terminal surface of conical pad body is protruding, have above effect, and simultaneously, protruding through the hemisphere, make the lower terminal surface of conical pad body and by leave the clearance between the mounting surface, thereby switched on the louvre, through-hole and clearance, improve gas mobility, and has good air permeability, and excellent heat-sinking capability is realized.

Specifically, the radiating fins 5 are of a T-shaped structure;

the bottom of the through hole 2 of the conical gasket body 1 is inwardly contracted, so that the thickness of the upper end face of the conical gasket body is smaller than that of the lower end face, the conical gasket body with the structure has better pressure resistance, and the service life of the gasket is prolonged.

In order to further improve the heat dissipation capacity, a heat dissipation layer 7 is compounded on the outer surface of the conical gasket body through a compounding process; the heat dissipation layer 7 is a polyimide layer, and the thickness of the polyimide layer is 0.1-0.3 mm.

The number of the hemispherical bulges is at least 4, and the hemispherical bulges are circumferentially arranged along the upper end surface or the lower end surface of the conical gasket body.

The utility model discloses a set up louvre and fin, make the gasket have fine heat-sinking capability, can be applicable to in the radiating environment of needs, improve the application scope of gasket, have simple structure, low cost's advantage.

The skilled person should understand that: although the present invention has been described in terms of the above embodiments, the inventive concepts are not limited to the embodiments, and any modifications that utilize the inventive concepts are intended to be included within the scope of the appended claims.
