In the figure: 1. the heat dissipation device comprises an upper backing ring, 11, a clamping groove, 2, a lower backing ring, 21, a clamping column, 3, a sealing ring, 31, a groove, 32, a mounting hole, 33, a high-temperature-resistant glass fiber wire, 4 and a heat dissipation opening.
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 work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: a metal gasket without steel belt seal comprises an upper backing ring 1, a lower backing ring 2 and a sealing ring 3, wherein the lower surface of the upper backing ring 1 is provided with a clamping groove 11, the upper surface of the lower backing ring 2 is fixedly provided with a clamping column 21, the upper surface of the sealing ring 3 is provided with a mounting hole 32 in a penetrating way, the clamping column 21 is arranged in the clamping groove 11 in a penetrating way through the mounting hole 32 in a clamping way, the lower surface of the sealing ring 3 is provided with a groove 31, the inner surface of the groove 31 is attached to the outer surface of the lower backing ring 2, and the upper surface of the upper backing ring 1 is provided with a heat radiation port 4 in a penetrating way, when the combination is carried out, the clamping column 21 of the lower backing ring 2 firstly penetrates through the mounting hole 32 of the sealing ring 3, then with lower backing ring 2 whole card in the recess 31 of sealing ring 3, then the draw-in groove 11 position of backing ring 1 is seen visually, will block that the post 21 card goes into in the draw-in groove 11 with sealing ring 3 centre gripping between last backing ring 1 and lower backing ring 2 can, during the use with normal gasket the same use can.
Specifically, the high temperature resistant glass fiber threads 33 are arranged inside the sealing ring 3 in a vertical and horizontal crossing manner, and the durability of the sealing ring 3 in a high temperature environment can be increased by arranging the high temperature resistant glass fiber threads 33 inside the sealing ring 3.
Specifically, the height of the groove 31 is 1.2 times the height of the lower backing ring 2, so that the sealing ring 3 can contact the surface of the conductor to seal when the gasket is used.
