Description
Technical Field
The utility model relates to a turbo charger's seal structure specifically is a compound heat exchanger that separates for strengthening booster whirlpool end is sealed.
Background
The turbocharger heat shield is positioned at the joint of a turbine shell of the turbocharger and a supercharger intermediate body, is tightly matched with the turbine shell and the supercharger intermediate body, and has a certain compression amount during assembly. The heat shield has the functions of preventing excessive high heat of engine exhaust gas in the turbine shell from being conducted to an intermediate body containing high-speed rotating parts, preventing a plurality of important parts of the supercharger from being influenced by high temperature and optimizing the internal working environment of the supercharger. After the existing heat shield is used for a period of time, the heat shield is easy to generate plastic deformation, so that the heat shield cannot be in close contact with an upper fixed disk and an intermediate body of a turbine shell, the heat-insulating sealing capacity of the heat shield is reduced, when an engine has higher vibration strength, high-temperature waste gas in the turbine shell flows to the intermediate body and a moving mechanism assembly through a gap generated by deformation of the heat shield, and heat and carbon deposition of the high-temperature waste gas can quickly deform and clamp moving parts of the moving mechanism assembly, so that the service life of a supercharger is reduced and the supercharger is damaged.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a compound heat exchanger that separates for strengthening booster whirlpool end is sealed, this.
In order to solve the technical problem, the provided composite heat shield for strengthening the sealing of the vortex end of the supercharger comprises a heat shield body located between a supercharger intermediate body and a turbine shell, wherein a through hole is formed in the middle of the heat shield body, and an outwards bent sealing ring edge is arranged on the outer periphery of the heat shield body.
The outer ring section of the sealing spacer ring is fixedly connected to the sealing ring edge, and a gap is formed between the inner ring section of the sealing spacer ring and the sealing ring edge.
The width of the gap is 1-3 times of the thickness of the sealing spacer ring.
The outer diameter of the sealing spacer ring is not larger than that of the sealing ring edge.
The sealing spacer ring is fixedly connected to the edge of the sealing ring in a welding or bonding mode.
The outer surface of the packing spacer ring has a plurality of corrugated protrusions or ridges.
After adopting above-mentioned structure, because the interior external surface along the sealing ring has all set up elastic sealed spacer ring, therefore during the assembly, turbine shell and midbody close coupling can extrude elastic sealed spacer ring, the bellying of sealed spacer ring receives extrusion deformation, thereby carried out the sealed of great area, the sealed requirement under bigger heat altered shape and the higher vibration intensity, seal reliability greatly increased between heat exchanger and turbine shell and the midbody, avoid appearing the condition of gas leakage, turbo charger's power has been guaranteed.
To sum up, the utility model has the advantages of strengthen the sealed reliability between heat exchanger and turbine shell and the midbody, avoid appearing the condition of gas leakage and guarantee turbocharger power.

Detailed Description
Referring to fig. 1 to 4, the present invention provides a composite heat shield for enhancing the vortex end seal of a supercharger, and the connection structure of each component is only illustrated in fig. 1, and is not limited to the specific structure. The composite heat shield comprises a heat shield body 10 located between a supercharger intermediate 20 and a turbine shell 30, wherein a through hole is formed in the middle of the heat shield body 10, an outwards bent sealing ring edge 11 is arranged on the outer periphery of the heat shield body 10, the outer surface and the inner surface of the sealing ring edge 11 are respectively connected with an elastic sealing spacer ring 1, the left side in the figure 1 is used as the inner surface of the sealing spacer ring 1, a protruding portion 2 is arranged on the sealing spacer ring 1, the protruding portion on the inner side of the sealing spacer ring 1 protrudes inwards, and the protruding portion on the outer side of the sealing spacer ring 1 protrudes outwards.
Referring to fig. 1 to 4, an outer ring section of the seal spacer ring 1 is fixedly connected to the seal ring edge 11, and a gap is formed between the inner ring section of the seal spacer ring 1 and the seal ring edge 11; in this embodiment, the inner ring section with a gap of 1-3 times the thickness of the sealing spacer 1 constitutes the projection 2.
Referring to fig. 1 to 4, the external diameter of sealed spacer ring is not more than the external diameter that the sealing ring was followed, and above-mentioned structure can guarantee that sealed spacer ring 1 when receiving extrusion back elastic deformation, can not produce interference and crooked scheduling problem, sealed spacer ring 1 adopts the mode rigid coupling of welding or bonding on sealing ring edge 11 the utility model discloses in, because sealed spacer ring adopts the elastic steel piece, can adopt the welded mode to realize above-mentioned rigid coupling. The outer surface of the sealing spacer ring has a plurality of corrugated ridges or ridges, which are not shown, but may, of course, be closely spaced in the transverse or longitudinal direction, in order to further enhance the sealing of the heat shield against vibration.
The utility model discloses do not receive the restriction of above-mentioned embodiment, at this technical field personnel, based on the utility model discloses the simple replacement of the equivalent change of concrete structure and method step is all in the protection scope of the utility model.
