Description
Technical field
The utility model is related to a kind of cooler for recycled exhaust gas structure, specifically a kind of EGR suitable for 4V serial diesel engines
Cooler construction, belongs to cooler field.
Background technology
Requirement with ring both at home and abroad to engine emission is more and more stricter, how to reduce Engine Emissions thing, special
It is not the discharge of NOx and PM, it has also become the important topic of current internal combustion engine industry research.EGR（exhaust gas
Recirculation, waste gas recycling）Technology is to reduce NOx gases to discharge effective means.Cooler for recycled exhaust gas is used as egr system
Critical piece a pair of control discharge play highly important effect.
Before the utility model is made, in prior art, because engine actual operating mode scope is wider, in difference
Operating mode under, there is larger difference in the exhaust gas flow for flowing through cooler for recycled exhaust gas, cause conventional water-cooled cooler for recycled exhaust gas to occur as soon as
Cooling is not enough or excess coolant problem, and this uncontrollable factor can cause engine performance and deterioration of emission, in cooler for recycled exhaust gas
Portion's gum deposit, cooling effectiveness decline even blocking.
The content of the invention
The purpose of this utility model is to overcome above-mentioned weak point, so as to provide a kind of EGR cooler for diesel structure；
The structure makes EGT controllable by controlling by-passing valve, so as to optimize the performance under each operating mode of engine and discharge, it is to avoid EGR
Occur gum deposit, cooling effectiveness inside cooler and decline the problems such as even blocking, the reliability of engine can be improved.
According to the technical scheme that the utility model is provided, a kind of cooler for recycled exhaust gas structure includes gas inlet end, cylinder, gives up
Gas outlet side, be characterized in：Cylinder two ends are connected with gas inlet end, waste gas outlet side by bolt respectively；Waste gas outlet side fills
There are vacuum actor and by-passing valve；The by-passing valve is arranged in waste gas outlet side.
As further improvement of the utility model, the rectangular cross-section of the cylinder, it is by two, cooling chamber, waste gas chamber
Independent inner chamber composition；More than two tracheaes excessively being evenly arranged are provided with the cooling chamber, the gap crossed between tracheae is formed
Hydroecium, hydroecium is connected with water inlet, delivery port respectively.
Used as further improvement of the utility model, the section of the by-passing valve is sector, and fan-shaped angle is：70 ° -76 °,
Fan-shaped radius is：11-12mm.
Used as further improvement of the utility model, the vacuum controller can control by-passing valve to rotate, and the anglec of rotation is：
0°-90°。
Compared with the prior art the utility model has advantages below：
It is the utility model simple structure, compact, reasonable, make EGT controllable by controlling by-passing valve, so as to optimize hair
Performance and discharge under each operating mode of motivation, it is to avoid occur gum deposit, cooling effectiveness decline even blocking etc. inside cooler for recycled exhaust gas and ask
Topic, improves the reliability of engine.

Specific embodiment
The utility model will be further described with reference to the embodiment in accompanying drawing below：
As shown in Fig. 1 ~ 3, a kind of cooler for recycled exhaust gas structure includes gas inlet end 1, cylinder 4, waste gas outlet side 5, cylinder 4
Two ends are connected with gas inlet end 1, waste gas outlet side 5 by bolt respectively；Waste gas outlet side 5 is equipped with vacuum actor 9 and side
Port valve 6；The by-passing valve 6 is arranged in waste gas outlet side 5.
The rectangular cross-section of the cylinder 4, it is made up of cooling chamber 3, the independent inner chamber in 2 two, waste gas chamber；The cooling chamber 3
Inside be provided with more than two be evenly arranged cross tracheaes 10, cross tracheae 10 between gap formed hydroecium 11, hydroecium 11 respectively with
It is connected with water inlet 8, delivery port 7.
Vacuum actor 9 includes that vacuum actor housing 12, barrier film 13, return spring 14, execution bar 15 are constituted, described true
Barrier film 13, return spring 14 are provided with empty actuator housing 12；Perform in the insertion vacuum actor of bar 15 housing 12, described
Vacuum port and atmosphere entry are offered on vacuum actor housing 12.
The section of the by-passing valve 6 is sector, and fan-shaped angle is：70 ° -76 °, fan-shaped radius is：11-12mm.
The vacuum actor 9 receives extraneous input and starts action, and control by-passing valve 6 rotates in direction, rotates as shown in Figure 3
Angle is：0°-90°.So as to control the exhausted air quantity by cooling chamber 3 to change from 0-100%, realize that waste gas air outlet temperature is controllable.
It is the utility model simple structure, compact, reasonable, make EGT controllable by controlling by-passing valve, so that starting
Performance and discharge under each operating mode of machine are optimized, and improve the reliability of engine.
