Abstract
The utility model relates to an EGR (exhaust gas recirculation) cooler for a diesel engine. The EGR cooler comprises a cooler body 1 integrating an EGR cooler valve seat 2 and a bypass switch valve 3, wherein the cooler body 1 adopts a U-shaped pipe structure capable of favorably improving the cooling efficiency, the EGR cooler valve seat 2 and the bypass switch valve 3 are arranged at the same end of the cooler body 1, and the installing hole position a of the EGR cooler valve, the EGR waste gas outlet hole position b, the EGR waste gas inlet hole position c and the installing hole position d of the bypass switch valve 3 are integrated by the EGR cooler valve seat. The EGR cooler for the diesel engine has the advantages that cooler body adopts a U-shaped pipe, the cooling efficiency is improved, and meanwhile, the arrangement space is saved. The EGR cooler valve seat realizes the high integration, and the size of an EGR cooler assembly is greatly reduced. An EGR cooler support body with a cooling water inlet passage e is welded with the cooler body, the fixed supporting effect can be realized, the space can also be saved, the cooler can be directly connected with a cylinder cover, and the additional addition of a cooling water inlet pipeline is not needed.
Description
Technical field
The utility model relates to a kind of cooler for recycled exhaust gas of diesel engine.
Background technique
Along with the continuous reinforcement to environmental consciousness, the improving constantly of motor emission level, EGR is playing the part of indispensable role in the process that promotes emission level, traditional EGR is connected design with cooler unreasonable, and cooling effect is lower, and loosely organized, volume is larger, is not easy to install.
Summary of the invention
For effectively improving the cooling effectiveness to EGR waste gas, the utility model provides a kind of cooler for recycled exhaust gas for diesel engine, to make up the deficiencies in the prior art.The cooler for recycled exhaust gas that the application provides can reach higher cooling effectiveness under identical condition than traditional cooler for recycled exhaust gas, be especially applicable to being arranged on the diesel engine of limited space.
The technical solution of the utility model is as follows:
A kind of cooler for recycled exhaust gas of diesel engine, the cooling body that has comprised cooler for recycled exhaust gas valve seat and bypass cock valve integrated, described cooling body adopts the U-shaped tubular construction that is conducive to improve cooling effectiveness, cooler for recycled exhaust gas valve seat and bypass cock valve are arranged on same one end of cooling body, described cooler for recycled exhaust gas valve seat the is integrated mounting hole site a of cooler for recycled exhaust gas valve, the air outlet hole position b of EGR waste gas and the mounting hole site d of inlet hole position c and bypass cock valve.
On the external wall of described cooler, welding is with the support of cooling water intake tunnel e.
Between described cooler for recycled exhaust gas valve seat and support, increased the auxiliary support plate of reinforcement effect.
Advantage of the present utility model and good effect are:
This EGR cooler for diesel that the application provides, cooling body adopts U-shaped pipe, when increasing cooling effectiveness, has saved arrangement space.The integrated volume that significantly dwindles cooler for recycled exhaust gas assembly of cooler for recycled exhaust gas valve seat height.With the cooler for recycled exhaust gas support of cooling water inlet channel e, together with cooling body seam, can play the effect of fixed support, save again space.Cooler can directly be connected with cylinder cap, without additional cooling water inlet pipe road.
accompanying drawing explanation:
Fig. 1 is example structure schematic diagram of the present utility model.
Fig. 2 Shi Tu1Zhong back side shaft side figure.
Fig. 3 is the cut-away view of cooling body (1).
Fig. 4 is support (4) the assembling schematic diagram of looking up reflection.
Number in the figure is: cooling body 1, cooler for recycled exhaust gas valve seat 2, bypass cock valve 3, support 4, auxiliary support plate 5.
embodiment:
Below in conjunction with embodiment and accompanying drawing, be described further.
As Figure 1-4, this EGR cooler for diesel that the utility model provides, by the cooling body 1 of U-shaped tubular construction, cooler for recycled exhaust gas valve seat 2, bypass cock valve 3 and with the parts such as support 4 of cooler for recycled exhaust gas inlet pipeline, form, for high efficiency cooling EGR waste gas.Cooling body adopts U-shaped pipe, when increasing cooling effectiveness, has saved arrangement space.The mounting hole site d of the air outlet hole position b of cooler for recycled exhaust gas valve seat the is integrated mounting hole site a of EGR valve, EGR waste gas and inlet hole position c, bypass cock valve, the highly integrated volume that significantly dwindles cooler for recycled exhaust gas assembly.With the cooler for recycled exhaust gas support of cooling water inlet channel e, together with the seam of cooler for recycled exhaust gas body, can play the effect of fixed support, save again space.Cooler can directly be connected with cylinder cap, without additional cooling water inlet pipe road.Between cooler for recycled exhaust gas valve seat and support, increase auxiliary support plate 5 and reinforce valve seat.
