Description
Technical field
A kind of exhaust gas recirculation device is the utility model is related to, more particularly to a kind of exhaust gas used on automobile is again
Circulator.
Background technology
The exhaust gas of general automobile includes the harmful substances such as carbon monoxide, oxynitrides, hydrocarbon, these nuisances
Matter causes emission performance not according to various item differences such as the braking condition of engine, air ratio, ignition timing, mixer apparatus
Together, produced when especially oxynitrides is mainly the big temperature high pressure in combustion chamber and air excess.In cylinder combustion
Oxynitrides yield significantly reduces when Indoor Combustion temperature reduces, in order to be produced when reducing mixer burning using this point
Oxynitrides, occur exhaust gas recirculation device on the market.So current discarded recycling device enters heat exchange by discarded
Heat exchange is carried out with coolant in pipe, so, current this cooling device structure is simultaneously unreasonable, and exhaust gas is flowed in heat exchanger tube
When dynamic, exhaust gas is big in heat exchange pipe internal surface flow resistance, and exhaust gas flowing velocity is substantially reduced, therefore can realize quick cooling, and
Exhaust gas positioned at the tube hub that exchanges heat is because resistance is small, and cooling velocity is poor, and cooling effectiveness is low, so as to lead to not reach exhaust gas recycling
The function of device.And when long-time is used since exhaust gas flow velocity is low, heat exchanger tube interior surface absorption soot, therefore cause
The diameter of heat exchanger tube diminishes, and exhaust gas smooth can not provide, the various problems such as cooling capacity is low.

Outlet mouth of pipe, the air inlet mouth of pipe are connected by exhaust gas isocon with the exhaust manifold of automobile engine, and the outlet mouth of pipe is led to
Cross exhaust gas recirculation pipe to connect with the inlet manifold of engine, coolant inlet is provided with the cooling chamber and coolant goes out
Mouthful, the coolant inlet and cooling liquid outlet are connected with coolant circulation unit, if being both provided with the pipe of every heat exchanger tube
The turbulator rod of dry root radial direction, and in each turbulator rod in same root heat exchanger tube at least two turbulator rods extending direction it is different.
As a preferred solution, the quantity of the heat exchanger tube is seven, and wherein six roots of sensation heat exchanger tube cloth is distributed in positive six
On six vertex of side shape, a remaining heat exchanger tube is arranged at the center of the regular hexagon.
As a preferred solution, the turbulator rod on each heat exchanger tube on the vertex of regular hexagon includes the
A kind of turbulator rod, the second class turbulator rod and three classes turbulator rod, first kind turbulator rod and the second class flow-disturbing on each heat exchanger tube
Bar extends through the heat exchanger tube on two vertex adjacent thereto, first kind turbulator rod and the second class turbulator rod constitute it is described just
The side of hexagon, the three classes turbulator rod on each heat exchanger tube run through the heat exchanger tube at the center in regular hexagon and opposite top
The heat exchanger tube of point, the three classes turbulator rod constitute the diagonal of the regular hexagon.
As a preferred solution, the quantity of the three classes turbulator rod on each heat exchanger tube on regular hexagon vertex
To be multiple and be equally spaced.
As a preferred solution, the turbulator rod is cylindrical turbulator rod.
After employing above-mentioned technical proposal, the effect of the utility model is：Due to being both provided with the pipe of every heat exchanger tube
The turbulator rod of some radial directions, and in each turbulator rod in same root heat exchanger tube at least two turbulator rods extending direction not
Together, therefore, by exhaust gas, sinuous flow state flows at a uniform rate in heat exchanger tube, and fully heat is realized between exhaust gas and heat exchanger tube
Exchange, exhaust gas temperature enters back into the inlet manifold of engine after reducing, make the exhaust gas temperature of supply combustion chamber reduce, so as to improve
Efficiency of combustion, reduces the generation of oxynitrides, and exhaust gas is sinuous flow state in heat exchanger tube, therefore the uniformity higher that exchanges heat, no
Heat transfer tube wall temperature easily occur reduces too fast and carbon deposition phenomenon occurs.
Again since the turbulator rod on each heat exchanger tube on the vertex of regular hexagon includes first kind turbulator rod, the
Two class turbulator rods and three classes turbulator rod, first kind turbulator rod on each heat exchanger tube and the second class turbulator rod extends through and it
Heat exchanger tube on two adjacent vertex, first kind turbulator rod and the second class turbulator rod constitute the side of the regular hexagon, often
Three classes turbulator rod on a heat exchanger tube runs through the heat exchanger tube at center and the heat exchanger tube of opposed apexes in regular hexagon, should
Three classes turbulator rod constitutes the diagonal of the regular hexagon, and so each heat exchanger tube just constitutes a combination heat exchange core body,
Fixation is more firm between heat exchanger tube, and mutually with certain involve power, the comparison of heat exchanger tube is simple, and turbulator rod is easy for installation.
Again since the turbulator rod is cylindrical turbulator rod, so not only facilitate exhaust gas to bypass turbulator rod, reduce turbulator rod
The resistance brought.
