Abstract
The utility model discloses the cooler for recycled exhaust gas of a kind of band corrugated tube, belong to the cooler for recycled exhaust gas used in Exhaust Control of Engine, including cooler for recycled exhaust gas and EGR corrugated tube, also include cooler for recycled exhaust gas flange, described cooler for recycled exhaust gas flange one end is cast as cooler for recycled exhaust gas external diameter size, the other end is cast as EGR outside diameter of bel size, is linked together with cooler for recycled exhaust gas by EGR corrugated tube with cooler for recycled exhaust gas flange.May insure that cooler for recycled exhaust gas in use cooling effectiveness does not declines, and simple in construction, volume is little, conveniently disassembles, and saves space.
Description
Technical field
This utility model belongs to engine emission field, the internal combustion engine cooler for recycled exhaust gas of a kind of band corrugated tube.
Background technology
At present, electromotor uses EGR rate control burning and reduces discharge, arrange that installing space constrains the layout of EGR,
Reduce EGR volume, the efficiency of cooler for recycled exhaust gas, impact discharge can be reduced.
Summary of the invention
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, it is provided that the EGR of a kind of band corrugated tube
Cooler.A corrugated tube is increased in cooler for recycled exhaust gas, easy for installation；Its simple in construction, volume are little, can make space more
Reasonable Arrangement, overcomes existing installing space not enough, and improves inlet end pressure, reduce pressure drop, and favourable EGR rate controls.
This utility model is achieved by following technical solution: the cooler for recycled exhaust gas of a kind of band corrugated tube, cold including EGR
But device and EGR corrugated tube, also includes that cooler for recycled exhaust gas flange, described cooler for recycled exhaust gas flange one end are cast as outside cooler for recycled exhaust gas
Footpath size, the other end is cast as EGR outside diameter of bel size, with cooler for recycled exhaust gas flange by EGR corrugated tube and cooler for recycled exhaust gas
Link together.
Preferably: be welding as one with EGR corrugated tube and cooler for recycled exhaust gas with cooler for recycled exhaust gas flange.
Advantage of the present utility model and providing the benefit that:
1. simple in construction, volume are little, save space, the layout of cooler for recycled exhaust gas easy to maintenance, favourable.
2. improve the reliability of engine EGR system.
3. maintain cooler for recycled exhaust gas cooling effectiveness, reduce discharge.
Accompanying drawing explanation
Fig. 1 is the structural representation of the cooler that this utility model provides.
In figure: 1 be EGR corrugated tube, 2 be cooler for recycled exhaust gas flange, 3 for cooler for recycled exhaust gas cooler.
Detailed description of the invention
Below in conjunction with the accompanying drawings 1 and specific embodiment the utility model is described in further detail.
Connected mode between cooler for recycled exhaust gas 3 and EGR corrugated tube 1 being optimized, flange uses forging type, flange
One end is cast as cooler for recycled exhaust gas 3 external diameter size, and one end is cast as EGR corrugated tube 1 external diameter size, obtains EGR cooling after processing
Device flange 2, links together EGR corrugated tube 1 with cooler for recycled exhaust gas 3 with cooler for recycled exhaust gas flange 2, and using soldering to be welded is one
Body, it is also possible to EGR corrugated tube 1 any direction is adjusted.
As can be seen from the above technical solutions, by EGR corrugated tube 1 and cooler for recycled exhaust gas 3 integrator, compact conformation,
It is artistically decorated, is conducive to installing, reduces cost of labor, save the time.
Claims (2)
1. a cooler for recycled exhaust gas for band corrugated tube, including cooler for recycled exhaust gas (3) and EGR corrugated tube (1), it is characterised in that: also wrap
Including cooler for recycled exhaust gas flange (2), described cooler for recycled exhaust gas flange (2) one end is cast as cooler for recycled exhaust gas (3) external diameter size, another
End is cast as EGR corrugated tube (1) external diameter size, with cooler for recycled exhaust gas flange (2) by EGR corrugated tube (1) and cooler for recycled exhaust gas (3)
Link together.
The cooler for recycled exhaust gas of a kind of band corrugated tube the most according to claim 1, it is characterised in that described cooler for recycled exhaust gas flange
(2) it is welding as one with cooler for recycled exhaust gas (3) and EGR corrugated tube (1).
