Abstract
The invention discloses a radiating tube of an EGR cooler, which comprises a radiating tube body with a straight through hole inside, wherein a plurality of supporting salient points are arranged on the upper side and the lower side of the radiating tube body, the supporting salient points on the upper side and the lower side are staggered in position, and the supporting salient points on adjacent radiating tubes are mutually supported on the outer wall of the radiating tube body after assembly. According to the radiating pipe of the EGR cooler, the plurality of supporting salient points are arranged on the upper side and the lower side of the radiating pipe, so that multi-point support is formed between the adjacent radiating pipes, the phenomenon that the radiating pipes are cracked due to overlarge internal pressure can be effectively avoided, and meanwhile, the cooling efficiency of the cooler can be improved to a certain degree.
Description
Technical Field
The invention relates to an EGR cooler, in particular to a radiating pipe of the EGR cooler.
Background
The flat radiating pipe of the EGR cooler is generally formed by bending and winding a plane plate, a straight through hole is formed in the finished radiating pipe after winding, waste gas for circulation is used in the straight through hole in use, a water flow channel of cooling water is formed in a gap between adjacent radiating pipes, and the cooling water cools the waste gas through heat exchange of the radiating pipes.
In above structure, the cooling tube both ends after the assembly are through carrying out the location with EGR refrigerated both ends flange and being connected, and do not set up corresponding bearing structure between the adjacent cooling tube, use through many years discovers, this structural setting has certain not enough, it is little to the little petrol engine influence of exhaust pressure, nevertheless to the great diesel engine of exhaust pressure ratio, can have very big potential safety hazard, in-service use, the condition that the cooling tube is propped up because of inside atmospheric pressure is too big occasionally can appear, and this will lead to the serious consequence that the engine intake.
Disclosure of Invention
In order to solve the above problems, the present invention provides a heat dissipation tube of an EGR cooler, wherein a plurality of support protrusions are disposed on upper and lower sides of the heat dissipation tube, so as to form a multi-point support between adjacent heat dissipation tubes, thereby effectively preventing the heat dissipation tube from cracking due to an excessive internal pressure, and simultaneously increasing the cooling efficiency of the cooler to a certain extent.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides a cooling tube of EGR cooler, includes the cooling tube body of the straight through hole of an inside area, its characterized in that: the last downside of cooling tube body all is provided with a plurality of support bumps, and the support bump of going up the downside staggers each other in the position, supports the bump on the adjacent cooling tube of assembly back and props up each other and hold on the outer wall of cooling tube body.
More specifically, the supporting salient points are arranged in a spherical crown shape, and the top of the supporting salient points is provided with a connecting plane.
More specifically, each of the support protrusions forms an inner groove in an inner wall of the through hole.
More specifically, the radiating pipe body is densely provided with inner convex points on the inner side wall of the through hole.
More specifically, the shape of the inner salient point is one or more of a circle, a square or a long strip.
The upper side and the lower side of the radiating pipe body are provided with the plurality of supporting salient points which are staggered mutually, and the supporting salient points can be propped against the surfaces of the adjacent radiating pipes after the radiating pipes are assembled, so that multi-point support is formed between the adjacent radiating pipes, and the radiating pipe structure has the characteristics of wide supporting range, uniform stress and high supporting strength.
Above cooling tube that has the support bump can not only effectively promote the self intensity of cooling tube to can promote the bulk rigidity of cooler, can stop the burst phenomenon that takes place because of inside exhaust gas pressure is too big in the use.
In addition, corresponding inner grooves can be formed on the inner side walls of the through holes due to the arrangement of the supporting salient points, the inner grooves can improve the turbulence effect of airflow, slow down the flow velocity of the airflow and improve the cooling efficiency of waste gas; on the other hand, the supporting salient points form partition columns between the adjacent radiating pipes so as to have turbulence effect on the cooling water, slow down the flow velocity of the cooling water, provide more time for the heat exchange of the cooling water and further improve the cooling efficiency of the cooler.

Detailed Description
As shown in fig. 1-3, a heat pipe of an EGR cooler comprises a heat pipe body 1 having a through hole 11 therein, wherein a plurality of supporting protrusions 12 are disposed on the upper and lower sides of the heat pipe body 1, and the supporting protrusions 12 on each side may be arranged in one or more rows. The supporting salient points 12 on the upper side and the lower side are staggered in position, and the supporting salient points 12 on the adjacent radiating pipes are mutually propped against the outer wall of the radiating pipe body after assembly.
The support protrusions 12 are shaped in a spherical crown shape so that the outer wall thereof minimizes the obstruction of the flow of the cooling water. Meanwhile, the connection plane 121 is provided at the top of the support protrusion 12, and the connection plane 121 can make a large-area contact with the surface of the radiating pipe body 1 of the adjacent radiating pipe, thereby obtaining a better support effect.
The support bump 12 that sets up more than, can be at the cooling tube assembly back top and hold 1 surfaces of cooling tube body at adjacent cooling tube to make and form the multiple spot between the adjacent cooling tube and support, have the characteristics that the support range is wide, the atress is even, support intensity is high, its self intensity that can not only effectively promote the cooling tube, and can promote the bulk rigidity of cooler, can stop the cooling tube and use because of inside exhaust gas pressure too big emergence strut the split phenomenon.
Here, the processing of the above supporting convex points 12 is generally performed by stamping a planar plate, so that each supporting convex point 12 correspondingly forms a corresponding inner groove 122 on the inner side wall of the through hole 11, and the inner groove 122 forms a turbulent flow effect on the air flow in the through hole 11, so as to slow down the flow velocity of the air flow and improve the cooling efficiency of the exhaust gas; on the other hand, the supporting convex points 12 form a separating column effect between adjacent radiating pipes to form a turbulent flow effect on the cooling water, so as to slow down the flow rate of the cooling water, provide more time for the heat exchange of the cooling water, and further improve the cooling efficiency of the cooler.
Furthermore, for the cooling effect that can further strengthen the cooling tube, the inside wall of through hole 11 is covered densely at cooling tube body 1 and is provided with interior bump 13, the shape of interior bump 13 is one or more in circular, square or rectangular shape, and this interior bump 13 can form the vortex effect to the air current that flows through in the through hole 11, and then slows down the air current velocity of flow, provides more time for the heat exchange of air current, can promote the cooling efficiency of waste gas at to a great extent.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any simple modification, equivalent change or modification made to the above embodiments according to the technical principle of the present invention still falls within the scope of the technical solution of the present invention.
