Abstract
The invention relates to an EGR (exhaust gas recirculation) cooler, which is characterized by comprising a rectangular shell, a front cover, a tail cover, a partition sheet, a front main plate, a rear main plate and a gas guide pipe. The EGR cooler has the advantage of fast reducing the temperature of vehicle exhaust gas.
Description
Technical field
The present invention relates to a kind of cooler, relate in particular to a kind of cooler for recycled exhaust gas.
Background technique
Contain multiple harmful gas in vehicle exhaust, major pollutants are hydrocarbon, oxynitrides, carbon monoxide, sulfur dioxide, lead-containing compounds, Benzpyrene and solid particulate matter, can cause photochemical smog etc.For reducing the tail gas noxious gas emission, make it meet the up-to-date emission standard in various countries.Lead-containing compounds can be used without lead oil, other pollutants also can improve oil quality and reduce its content, but the NOx discharge can't change by oil product, therefore automobile vendor researches and develops EGR (EGR) system that can reduce the NOx discharge in succession, it can effectively reduce the discharge of NOx, and cooler for recycled exhaust gas is one of egr system important spare part.
Summary of the invention
For above shortcoming, the object of the present invention is to provide a kind of cooler for recycled exhaust gas of energy fast reducing vehicle exhaust temperature.
Technology contents of the present invention is: a kind of cooler for recycled exhaust gas is characterized in that it comprises long column shape shell, protecgulum, tail-hood, shim, front mainboard, rear mainboard and air pipe; Be provided with the water intake that communicates with the inner chamber of long column shape shell on the sidewall of long column shape outer casing back, be provided with the water outlet that communicates with the inner chamber of long column shape shell on the sidewall of long column shape shell front end, front mainboard sealing is fixed on long column shape shell front end, and rear mainboard sealing is fixed on long column shape outer casing back; Some row's air pipes are arranged in long column shape shell from top to bottom, and the air pipe front end stretches out front mainboard, and rear mainboard is stretched out in the air pipe rear end; Protecgulum is connected with long column shape shell forward end seal, laterally is provided with a shim in the inner chamber of protecgulum, and shim is divided into upper inner chamber and lower inner cavity by the inner chamber of protecgulum, and shim in the protecgulum air pipe that some rows stretch out front mainboard from top to bottom is divided into two-layer up and down; The some row's air pipes in upper strata communicate with upper inner chamber, the some row's air pipes of lower floor communicate with lower inner cavity, be provided with an air outlet hole identical with upper inner chamber at the protecgulum upside, at the protecgulum downside, be provided with an inlet hole identical with lower inner cavity, tail-hood and long column shape outer casing back are tightly connected.
In above-mentioned cooler for recycled exhaust gas, for strengthening the support to air pipe in long column shape shell, in long column shape shell, be provided with some support plates.
In above-mentioned cooler for recycled exhaust gas, for making gas, can from inlet hole, disperse to enter the air pipe lower inner cavity uniformly, the air inlet position in lower inner cavity is provided with two air-guide pieces, and two air-guide pieces become splayed shape from outside to inside.
The advantage that the present invention compared with prior art had is: energy fast reducing exhaust temperature of the present invention can import mixed gas in cylinder dilution cylinder, CO in cooling tail gas
2can not burn but can absorb heat, the exhaust temperature of discharge is reduced, thereby reducing the generation of NOx.

The structural representation that Fig. 3 is protecgulum.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, a kind of cooler for recycled exhaust gas, is characterized in that it comprises long column shape shell 1, protecgulum 2, tail-hood 3, shim 4, front mainboard 5, rear mainboard 6, air pipe 7, support plate 8 and air-guide piece 9; Be provided with the water intake 1.1 that communicates with the inner chamber of long column shape shell 1 on the sidewall of long column shape shell 1 rear end, be provided with the water outlet 1.2 that communicates with the inner chamber of long column shape shell 1 on the sidewall of long column shape shell 1 front end, front mainboard 5 sealings are fixed on long column shape shell 1 front end, and rear mainboard 6 sealings are fixed on long column shape shell 1 rear end; Some row's air pipes 7 are arranged in long column shape shell 1 from top to bottom, and air pipe 7 front ends stretch out front mainboard 5, and rear mainboard 6 is stretched out in air pipe 7 rear ends; Protecgulum 2 is connected with long column shape shell 1 forward end seal, laterally be provided with a shim 4 in the inner chamber of protecgulum 2, shim 4 is divided into upper inner chamber 2.1 and lower inner cavity 2.2 by the inner chamber of protecgulum 2, and shim in protecgulum 24 air pipe 7 that some rows stretch out front mainboard 5 from top to bottom is divided into two-layer up and down; The some row's air pipes 7 in upper strata communicate with upper inner chamber 2.1, the some row's air pipes 7 of lower floor communicate with lower inner cavity 2.2, be provided with an air outlet hole 2.3 identical with upper inner chamber 2.1 at protecgulum 2 upsides, be provided with an inlet hole 2.4 identical with lower inner cavity 2.2 at protecgulum 2 downsides, tail-hood 3 is connected with long column shape shell 1 back-end sealing; Be provided with some support plates 8 in long column shape shell 1; Inlet hole 2.4 places in lower inner cavity 2.2 are provided with two air-guide piece 9, two air-guide pieces 9 and become from outside to inside splayed shape.
Working principle of the present invention is: need cooling tail gas from inlet hole 2.4 through the dispersed lower inner cavity 2.2 that enters of two air-guide pieces 9, then from upper strata, some row's air pipes 7 enter inner chamber 2.1 again to enter tail-hood 3 through the some row's air pipes 7 of lower floor; Meanwhile cooling water enters after long column shape shell 1 inner chamber tail gas with air pipe 7 by water intake 1.1 and carries out heat exchange and flow out from water outlet 1.2, cooled tail gas from the air outlet hole 2.3 of inner chamber 2.1 flow out.
