Abstract

The utility model discloses a heat dispassion air ring which is one of the internal combustion engine piston rings. The air ring consists of a ring body and a heat dispassion ring; according to the structure of the ring body, the air ring can be divided into two types; one is an integral heat dispassion air ring, which is one or a plurality of ring grooves arranged in the middle of the external side of the ring body and the heat dispassion rings are inlayed in the ring grooves; the other is a split-type heat dispassion air ring, which is the ring body divided into two or a plurality of parts that are called an upper ring body and a lower ring body; the heat dispassion ring is jacketed between the upper and the lower ring bodies; a cross section of the ring body can be shaped in a rectangular or an L-shape, etc. The ring body and the heat dispassion ring are connected and fixed by a connecting part. The heat dispassion ring can be made by using metal materials with good thermal conductivity such as silver, copper or aluminum, etc. The heat dispassion air ring can not only ensure the sealing performance but also have good heat dispassion performances, which improves the defect of the original air rings that only emphasizes on the sealing performance but ignores the heat dispassion performances.

Description

The heat radiation compression ring

1, technical field

The utility model belongs to the compression ring in the internal-combustion engine piston ring, especially a kind of heat radiation compression ring.

2, background technique

Piston ring is the important part in addition of internal-combustion engine, and it is made of compression ring and oil ring; The main effect of compression ring is to ensure sealing between cylinder and piston, prevent gas leakage, it and a large amount of heats that piston head is absorbed conduct to cylinder wall. and compression ring is operated under the pernicious condition of high temperature, high pressure, high-speed motion and lubricated difficulty, and existing compression ring is only paid attention to the one side of its sealing, so only adopt single whole ferrous materials manufacturing.This is not enough to requiring a large amount of heat of compression ring conduction.

3, goal of the invention

Purpose of the present invention is exactly under the prerequisite that can ensure sealing, and the heat radiation compression ring of high efficiency and heat radiation function is arranged again.

4, summary of the invention

For reaching above-mentioned purpose, the utility model proposes a kind of knockdown heat radiation compression ring, its technological scheme is: this heat radiation compression ring is a constituent element in the piston ring, and it is made of ring body and heat dissipating ring, and its ring body structurc can be divided into integrated type and split type two kinds of structural types; And its heat dissipating ring can be with the good nonferrous materials manufacturing of heat-conducting property.

Above-mentioned integrated type heat radiation compression ring is to open one or more annular grooves at the outer middle side part of ring body, inlays heat dissipating ring in this annular groove, and ring body is connected with heat dissipating ring and fixes with link.

Above-mentioned split type heat radiation compression ring is that ring body is decomposed into two or more parts: be called upper ring body, lower ring body; And the shape of cross section of upper and lower ring body can be rectangle, multiple shape such as L shaped; Between upper and lower ring body, clamp heat dissipating ring, and upper ring body, lower ring body and heat dissipating ring are connected and fixing with link.

Above-mentioned heat dissipating ring is to make with multiple nonferrous materialss such as the good silver of heat-conducting property, copper or aluminium.

5, beneficial effect

The utility model heat radiation compression ring is that edge has pressed from both sides the good heat dissipating ring of heat dispersion on the compression ring body, so it can ensure sealability, can ensure good performance of heat dissipation again; Improve only the paying attention to sealing of existing compression ring and thinked little of the problem of thermal diffusivity.

6, description of drawings

Fig. 1 is: integrated type heat radiation compression ring elevation cross-sectional view.

Fig. 2 is: integrated type heat radiation compression ring plan view.

Fig. 3 is: integrated type heat transmission gas annulate shaft is to the link partial sectional view.

Fig. 4 is: integrated type heat radiation compression ring is the link partial sectional view radially.

Fig. 5 is: split type heat transmission gas annulate shaft is to the link partial sectional view.

Among the figure: the 1-heat dissipating ring, the axial link of 2-, the 3-ring body, 4-is link radially, the axial link of 5-, 6-upper ring body, 7-heat dissipating ring, 8-lower ring body.

7, embodiment

With reference to accompanying drawing 1-5, heat radiation compression ring structure of the present utility model is simple and easy, easily manufactured.The heat radiation compression ring is made up of ring body (3,6,8) and heat dissipating ring (1,7); Its ring body can be divided into integrated type and split type two kinds of structural types.

Integrated type heat radiation compression ring can be opened one or more annular grooves by middle side part outside ring body (3), in this annular groove, inlay heat dissipating ring (1), use again axial link (3) or radially link (4) ring body (3) is connected with heat dissipating ring (1) and is fixing, just become integrated type heat radiation compression ring.

Split type heat radiation compression ring is that ring body is decomposed into two or more parts; Be called upper ring body (6,7), lower ring body (8), between upper ring body (6) and lower ring body (8), clamp heat dissipating ring (7), and upper ring body (6), lower ring body (8) and heat dissipating ring (7) are connected and fixing with axial link (5).Just become split type heat radiation compression ring.

On the above-mentioned split type heat radiation compression ring, the shape of cross section of lower ring body (6,8) can be rectangle, multiple shape such as L shaped.

Above-mentioned heat dissipating ring (1,7) is to make with multiple nonferrous materialss such as the good silver of heat-conducting property, copper or aluminium.
