Description

A kind of engine exhaust cooler
Technical field
The present invention relates to a kind of cooler, especially relate to a kind of engine exhaust cooler.
Background technique
At present, along with the application prospect of supercharging gasoline engine more and more widely, row's warm water of motor is flat to be had significantly than naturally aspirated engine in the past and improves, under the real engine operating mode, consider the restriction of pressurized machine and after-treatment system, and unrestrictedly the row's of making temperature increases to temperature.Delivery temperature is the very important parameter of car load front deck, also very crucial concerning the layout of other parts of front deck, generally, motor will spraying into by too much cooling fuel oil, control motor row temperature, but this also brings the unfavorable of all many-sides, the oil consumption level of for example being brought increases, the ternary conversion efficiency is not in optimal working point or the like, at such problem, in the industry a kind of coolant exhaust Manifold technology is arranged at present, mainly be to carry out cylinder head cooling water and gas exhaust manifold integrated, but also be faced with the development cost height simultaneously, complex structure, technical risk is big, problems such as the part property continued to use difference.
Summary of the invention
The purpose of this invention is to provide engine exhaust cooler a kind of simple in structure, practical, solve the cooling problem of enmgine exhaust.
The technical solution adopted for the present invention to solve the technical problems is: a kind of engine exhaust cooler, it comprises the cooler body, be arranged side by side the exhaust passage in the cooler body, be symmetricly set on the water inlet and the weep hole at cooler body two ends, on the cooler body, have the bolt hole adaptive, also comprise the water cavity that forms between exhaust passage and the cooler body with motor.
When guaranteeing to reduce delivery temperature, do not influence the warming-up process of motor yet, before described water inlet, be provided with the cooling water control valve that is connected by the fill cycle pipeline.
Further, be provided with the temperature transducer that control cooling water control opening of valves is closed in described exhaust passage and engine exhaust road connecting end.
In order to make water circulation pipe be convenient to be connected, be connected by flange between described water inlet and weep hole and water inlet, the backwater circulation pipeline with water inlet, weep hole.
Further, described water inlet and weep hole are to protrude to be arranged on the cooler body.
In the present invention, described exhaust passage is four exhaust passages arranged side by side.
For convenience of the casting problem of engine exhaust cooler ironcasting and the sealing of the whole water cavity of assurance, described cooler adopts one-sided sealing, and opening side compresses by gasket seal and motor end face and is tightly connected.
Further, to be provided with the bolt hole that is used for vent gas cooler and gas exhaust manifold one are fixed on the exhaust side of engine be nine to described cooler body.
Beneficial effect of the present invention: owing in the cooler body, be arranged side by side the exhaust passage, be symmetrically arranged with water inlet and weep hole at cooler body two ends, the water cavity that between exhaust passage and cooler body, forms, also be provided with cooling water control valve by temperature transducer control open and close, make it simple in structure, be convenient to make, practicability is good, can solve the cooling problem of enmgine exhaust.
Below with reference to drawings and Examples, the present invention is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is for using the cooling system schematic representation of vent gas cooler.
Fig. 2 is an engine exhaust chiller configuration schematic representation of the present invention.
Fig. 3 is flange arrangement schematic representation among the present invention.
Among the figure: 1. cooler body, 2. exhaust passage, 3. water inlet, 4. weep hole, 5. water cavity, 6. bolt hole, 7. cooling water control valve, 8. temperature transducer, 9. fill cycle pipeline, 10. motor, 11. gas exhaust manifolds, 12. backwater circulation pipelines, 13. vent gas coolers, 14. flanges.
Embodiment
Embodiment 1, shown in Fig. 1,2 and 3, a kind of engine exhaust cooler, it comprises cooler body 1, be arranged side by side the exhaust passage 2 in the cooler body, be symmetricly set on the water inlet 3 and the weep hole 4 at cooler body 1 two ends, on the cooler body, have the bolt hole 6 adaptive, also comprise the water cavity 5 that forms between exhaust passage 2 and the cooler body 1 with motor 10.
Embodiment 2, when guaranteeing to reduce delivery temperature, also do not influence the warming-up process of motor, are provided with the cooling water control valve 7 that is connected by fill cycle pipeline 9 before described water inlet 3.Further, be provided with the temperature transducer 8 of controlling 7 open and close of cooling water control valve in described exhaust passage and engine exhaust road connecting end.Remaining is with embodiment 1.
Embodiment 3, are convenient to be connected with water inlet, weep hole in order to make water circulation pipe, are connected by flange 14 between described water inlet and weep hole and water inlet, the backwater circulation pipeline.
Further, described water inlet and weep hole are to protrude to be arranged on the cooler body 1.
In the present invention, described exhaust passage is four exhaust passages arranged side by side.
For convenience of the casting problem of engine exhaust cooler 13 ironcastings and the sealing of the whole water cavity of assurance, described cooler adopts one-sided sealing, and opening side compresses by gasket seal and motor end face and is tightly connected.
Further, to be provided with the bolt hole that is used for vent gas cooler and gas exhaust manifold one are fixed on the exhaust side of engine be nine to described cooler body.Remaining is with embodiment 1 or 2.
Utilize the vent gas cooler among the present invention, realize that the method for exhaust cooling is as follows:
(1) this vent gas cooler is connected between the air outlet flue and gas exhaust manifold of motor, reduces motor row temperature by engine cooling water.
(2) the vent gas cooler two ends are respectively the water inlet and the osculum of cooling water, guarantee the circulation of whole water circulating system.
(3) before the water inlet of vent gas cooler, a cooling water control valve is installed, this cooling water control valve will control cutting out and flow of cooling water according to the operating mode (promptly controlling according to the temperature transducer that is arranged on the engine exhaust road) of motor, when guaranteeing to reduce delivery temperature, do not influence the warming-up process of motor yet.
Specifically, when motor is in the warming-up operating mode, system will close the water circulation system of whole exhaust cooling by the cooling water control valve, and the delivery temperature of motor is not controlled, and guarantee the quick ignition of catalyzer.
When motor operates in the operating mode of middle high load even external characteristics, because row's temperature of this moment will be near 1000 degrees centigrade, temperature transducer will be controlled the cooling water control valve makes it be in opening state,---cooling water control valve 7---vent gas cooler 13---backwater circulation pipeline 12 is back to engine-cooling system at last by fill cycle pipeline 9 to make the cooling water that comes from motor 10.
As shown in Figure 2, the water cavity 5 that can be deflated in the cooler during through exhaust passage 2 when hot exhaust centers on, and this cooling water about about 95 degree, can exchange to the part exhaust gas heat cooling water greatly well, thereby reduces delivery temperature.
