Abstract
The utility model discloses a kind of structure-improved of Diesel engine cooler radiating tube, comprise the radiating tube body of inner hollow, the inwall of described body is provided with some groups of choked flows spaced apart protruding, spaced apart vertically with each choked flow projection in group, the choked flow raised position in adjacent sets staggers mutually.The structure-improved of the Diesel engine cooler radiating tube of the utility model design, it carries out redesign transformation to the reducing-flow structure on radiating tube, can effectively reduce radiating tube inwall carbon distribution and point corrosion, extends the service life of cooler.
Description
Technical field
The utility model relates to Diesel engine cooler, is specially a kind of structure-improved of Diesel engine cooler radiating tube.
Background technology
The Diesel engine of current domestic engine manufacturer production, in the design for promoting the cooling effectiveness of cooler for recycled exhaust gas, radiating tube 2 ' in cooler 1 ' is all arranged to spiral tube structure, as illustrated in fig. 1 and 2, the vibrational power flow of this helix tube, the cooling stroke of radiating tube 2 ' can be extended to a certain extent, simultaneously because of the choked flow effect of helicla flute 21 ' in helix tube, effectively can slow down the cooling flow velocity of tail gas, extend heat exchanger time, the lifting of cooler 1 ' cooling effectiveness is realized with this, but because the continuous concave inward structure of helicla flute 21 ' exists very large dead space, along with the reduction of tail gas cooling flow velocity, the carbon deposition phenomenon in helicla flute 21 ' can be caused very serious, not only have impact on the cooling effectiveness of radiating tube 2 ', the blocking of radiating tube 2 ' even can be caused time serious.
In addition, because the quality of domestic oil product is bad, containing a certain amount of chlorine, sulphur composition, when fuel oil is through imperfect combustion, the chloride of steam and some is contained in the high-temperature gas discharged, sulfide, these steam are under the effect of radiating tube 2 ' external refrigeration water, radiating tube 2 ' internal chamber wall forms the globule and chloride, sulfide reaction forms acidic materials and is deposited in the helicla flute 21 ' of spiral tube structure, directly cannot discharge because of it and cause acidic materials constantly concentrated concentrating and Pulvis Causticus heat pipe 2 ' inwall, cause cooler in use for some time, there is point corrosion in radiating tube 2 ' inwall, cooler 1 ' is made to leak and damage engine.
Utility model content
For the problems referred to above, the utility model devises a kind of structure-improved of Diesel engine cooler radiating tube, it carries out redesign transformation to the reducing-flow structure on radiating tube, can effectively reduce radiating tube inwall carbon distribution and point corrosion, extends the service life of cooler.
For achieving the above object, the utility model is by the following technical solutions:
A kind of structure-improved of Diesel engine cooler radiating tube, comprise the radiating tube body of inner hollow, it is characterized in that: the inwall of described body is provided with some groups of choked flows spaced apart protruding, spaced apart vertically with each choked flow projection in group, the choked flow raised position in adjacent sets staggers mutually.
Further, the shape of above-mentioned choked flow projection is that spherical projection or the yi word pattern that radially distributes are protruding.
Further, each choked flow projection is spacedly distributed setting in above-mentioned same group.
The topmost advantage of the utility model radiating tube is the choked flow projection that its inboard wall of tube body arranges convex, and each choked flow is protruding with the setting spaced apart of multiple spot shape, each choked flow projection can form certain resistance to the air-flow of process on the one hand, air-flow is advanced in the mode of wave, for the heat exchange of air-flow provides enough time, the multiple spot shape of each choked flow projection is spaced apart on the other hand can not produce dead space at inboard wall of tube body, effectively can reduce the carbon deposition phenomenon of tube wall, the water droplet simultaneously produced in radiating tube or acid hydrops also can be washed away very soon, acid solution is there will not be to deposit concentrated phenomenon, effectively can avoid the radiating tube point corrosion caused because oil product is bad.
Accompanying drawing explanation
The structural representation of Fig. 1, existing cooler;
The radiating tube partial enlargement cross-sectional schematic of Fig. 2, spiral tube structure;
Fig. 3, perspective view of the present utility model;
The perspective view of Fig. 4, the utility model the second embodiment.
Detailed description of the invention
As a kind of in Fig. 3 structure-improved of Diesel engine cooler radiating tube, comprises the radiating tube body 1 of inner hollow, the inwall of described body 1 is provided with some groups of choked flow projections 11 spaced apart.With the equi-spaced apart distribution vertically of each choked flow projection 11 in group, stagger mutually in protruding 11 positions of the choked flow in adjacent sets.At this, the choked flow projection 11 in the present embodiment is arranged to spherical projection, and the yi word pattern also can being arranged to as required in practice radially distribute is protruding, and its structure as shown in Figure 4.In addition also can be arranged to other similar bulge-structures as required, be not repeated at this.
The topmost advantage of the utility model radiating tube is the choked flow projection 11 that its inboard wall of tube body arranges convex, and each choked flow projection 11 is with the setting spaced apart of multiple spot shape, each choked flow projection 11 can form certain resistance to the air-flow of process on the one hand, air-flow is advanced in the mode of wave, for the heat exchange of air-flow provides enough time, the multiple spot shape of each choked flow projection 11 is spaced apart on the other hand can not produce dead space at inboard wall of tube body, effectively can reduce the carbon deposition phenomenon of tube wall, the water droplet simultaneously produced in radiating tube or acid hydrops also can be washed away very soon, acid solution is there will not be to deposit concentrated phenomenon, effectively can avoid the radiating tube point corrosion caused because oil product is bad.
The above, it is only better embodiment of the present utility model, not any pro forma restriction is done to utility model, every according to know-why of the present utility model to any simple modification made for any of the above embodiments, equivalent variations or modification, still belong in the scope of technical solutions of the utility model.
