The utility model discloses simple structure realizes the optimization of drainage through adjusting to separate the heat exchanger structure, and is actually also obvious to the promotion of turbine efficiency.
Description
Technical Field
The utility model relates to an automobile turbocharger field especially relates to a turbo charger's heat exchanger is separated to water conservancy diversion.
Background
In the structure of the turbocharger of the automobile, a heat shield is required to be installed, the heat shield is assembled between a volute and a middle body, the heat shield is directly contacted with exhaust gas discharged by an engine, and the top surface of the heat shield replaces a part of the bottom surface of a flow passage and plays a certain role in guiding the flow. The heat shield is usually used for a mixed flow turbocharger, the mixed flow turbine is sensitive to the incident direction and stability of airflow, the conventional design adjusts the flow guide by adjusting the inclination angle of the bottom surface of a volute flow passage or adds a small-angle inclination to the top surface of the heat shield, the change is difficult, and the volute flow passage is a blank surface, so that the manufacturing tolerance is large, the size is unstable, the actual efficiency improvement effect on the turbine is not obvious, but the heat shield structure is not changed fundamentally, so the flow guide effect is still to be improved, namely the acting efficiency of the mixed flow turbine also has a space for improving.
Disclosure of Invention
The utility model aims to solve the technical problem that a turbo charger's water conservancy diversion separates heat exchanger is provided, simple structure separates the optimization that the heat exchanger structure realized the drainage through the adjustment, and is actually also obvious to the promotion of turbine efficiency.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a turbo charger's water conservancy diversion separates heat exchanger, including separating the heat exchanger body, the front end middle part that separates the heat exchanger body be provided with circular shape concave part, the terminal surface of separating the heat exchanger body on be provided with the protruding muscle of round with the position that the lateral wall of concave part is connected, the surface of protruding muscle be circular-arcly.
The exhaust gas flow comes to touch the convex rib along the radial direction of the end face of the heat shield body and then deflects towards the direction of the turbine part in the direction shown in the figure, and the inclined blowing-in gas flow can blow the mixed flow turbine to do work more efficiently.
The surface of the convex rib is arc-shaped, so that the function of flow guiding can be well played.
The height of the convex rib is 0.2mm, the processing is convenient, and the height can meet the requirement.
Additionally, the bottom of the heat shield body is provided with a fixing extension part extending in the radial direction, the fixing extension part is installed between the volute and the middle body, and the heat shield body can be fixed by clamping the fixing extension part.
Has the advantages that: the utility model relates to a turbo charger's water conservancy diversion separates heat exchanger, simple structure separates the optimization that heat exchanger end face structure realized the drainage through the adjustment, because of separating heat exchanger itself to be the stamping workpiece, and the structural change is simple, and the size is stable, realizes easily and with low costs on making, actually also obvious to the promotion of turbine efficiency, and through the test, it is about 2% to improve waste gas work efficiency.

As shown in fig. 1-4. The utility model discloses embodiment relates to a turbo charger's heat exchanger that separates by water conservancy diversion, including separating heat exchanger body 1, the front end middle part that separates heat exchanger body 1 be provided with circular shape interior concave part 4, the terminal surface of separating heat exchanger body 1 on be provided with the protruding muscle 3 of round with the position that the lateral wall of interior concave part 4 is connected, the surface of protruding muscle 3 be circular-arcly.
As shown in fig. 4, the exhaust gas flow comes along the radial direction of the end face of the heat shield body 1 and hits the rib 3, and then deflects towards the direction of the turbine component in the direction shown in the figure, and the inclined blowing gas flow can blow the mixed flow turbine to do work more efficiently.
The surface of the convex rib 3 is arc-shaped, so that the diversion effect can be well played, the height of the convex rib 3 is 0.2mm, the processing is convenient, and the height can meet the requirement.
Additionally, the bottom of the heat shield body 1 is provided with a fixed extension part 2 extending in the radial direction, the fixed extension part 2 is installed between the volute and the middle body, and the heat shield body 1 can be fixed by clamping the fixed extension part 2.
It is not difficult to discover, the utility model discloses simple structure realizes the optimization of drainage through adjusting heat shield end face structure, because of heat shield itself is the stamping workpiece, the structural change is simple, and the size is stable, realizes easily and with low costs on making, actually also obvious to the promotion of turbine efficiency, through the test, improves waste gas and does work efficiency about 2%.
