Abstract
The utility model discloses a double stage supercharger uses but ware core of level intercooling, include the tube bank of compriseing a plurality of body, wherein, body middle part surface evenly is provided with the strip fin of outside salient, and the fin is parallel with the body axis, in the middle part of the body internal surface transversal personally submit quincunx. The beneficial effects of the utility model are that: reasonable in design, simple structure describes the body through the fin and cools off the pressure boost air, has the characteristics that heat radiating area is big, the cooling effect is good, simultaneously the utility model discloses import of the coolant liquid of cooler core and the structure of cooling liquid exit in one end are convenient for like this arrange that the coolant liquid of connecting the cooler passes in and out the body.
Description
Technical field
The utility model relates to a kind of cooler core, particularly relates to a kind of double-stage supercharger interstage cooler core.
Background technique
Two-step supercharging motor is while raising mixed gas density, the rising of mixture temperature certainly will be brought, the lifting of temperature is conversely to improving intake efficiency, reducing motor detonation pressure, reducing the oxynitrides in discharge and improve low engine speed performance and play reaction, and therefore the structure of cascade EDFA especially cooler core just seems particularly important.
Model utility content
For solving the deficiency of above-mentioned prior art, the purpose of this utility model is to provide the technological scheme of the diesel engine double-stage supercharger interstage cooler core of the large and good cooling results of a kind of heat diffusion area.
Invention thinking of the present utility model shows as: cooled pressurized air by finned tube bank, and the inner and outer wall of this pipe all have passed through the long-pending process of enlarged surface, adds the area that fluid thermal exchanges.
A kind of double-stage supercharger interstage cooler core, comprise the tube bank be made up of several bodys, described body center outer surface is evenly provided with strip fin outwardly, described fin and described body axis being parallel, and in the middle part of described body, internal surface cross section is quincunx;
Described tube bank front end is connected with cooling liquid inlet joint and cooling liquid outlet joint, and described tube bank rear end is welded with the pad be enclosed within described body, and the described pad being positioned at described tube bank rear end has end cap by an end cap Flange joint.
Described fin is provided with lines.
Described lines is ripple or screw thread.
Described cooling liquid inlet joint and be provided with O RunddichtringO between described cooling liquid outlet joint and described body.
Described pad is provided with the through hole that several are corresponding with described body, between described through hole, described pad is provided with groove.
The beneficial effects of the utility model are: reasonable in design, structure is simple, evenly be provided with fin body by outer surface to cool pressurized air, have that heat diffusion area is large, the advantage of good cooling results, and inner surface of tube body is quincunx, increases heat diffusion area further, better improves cooling effect, thus improve diesel engine charge density and pressurization system efficiency, improve the reliability of pressurized machine and the performance of diesel engine.Fin structure is not easy to be corroded and damaged, and service life is long, and the cooling liquid inlet of the utility model cooler core and cooling liquid outlet structure at one end, be convenient to arrange that the cooling liquid connecting cooler passes in and out body so simultaneously.Pad arranging groove, after welding, cuts off pad along groove, the impact of concentrating because welding the stress that causes can being eliminated.
Accompanying drawing explanation
Fig. 1 is the pipe structure schematic diagram of the utility model embodiment.
Fig. 2 is the body schematic cross-section of the utility model embodiment.
Fig. 3 is that the tube bank of the utility model embodiment uses schematic diagram.
Wherein, reference character is: 1, body; 2, O RunddichtringO; 4, internal surface; 5, outer surface; 6, joint; 7, pad; 8, end cap flange; 9, end cap.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Certainly, specific embodiment described herein only in order to explain the utility model, and is not used in restriction the utility model.
Embodiment 1
See Fig. 1, Fig. 2 and Fig. 3, the utility model provides a kind of double-stage supercharger interstage cooler core, comprise the tube bank be made up of five bodys 1, wherein, body 1 center outer surface 5 is evenly provided with strip fin outwardly, fin and body 1 axis being parallel, in the middle part of body 1, internal surface 4 cross section is quincunx.
Wherein, fin is provided with lines, lines is preferably ripple or screw thread.Tube bank one end is connected with cooling liquid inlet joint and cooling liquid outlet joint (joint 6 namely in Fig. 3), the tube bank the other end is welded with the pad 7 be enclosed within body 1, pad 7 is provided with the through hole corresponding with five bodys 1, pad 7 is welded on body 1, and pad 7 is connected with end cap 9 by an end cap flange 8.Pad 7 is provided with the through hole that several are corresponding with described body 1, between through hole, pad 7 is provided with groove.
Cooling liquid inlet joint and be provided with O RunddichtringO 2 between cooling liquid outlet joint and body 1.
Body 1 course of working is as follows: first pass through cold-extrusion technology, body 1 outer surface 5 is squeezed into fin, internal surface 4 is rolled into quincunx, each fin is arranged corrugated lines, add the quincuncial combination of upper inner surface 4 to increase inside and outside exterior heat exchange area, then the fin at body 1 two ends is carried out cutting and be rolled into cylindrical shape, make air effectively can pass in and out whole tube bank like this and form cooled region, the flowing of air can not be had influence on, reduce flow resistance, ensure charging efficiency.
The utility model is that bunchy uses.Tube bank front tab 6 adds two O RunddichtringOs 2, can meet sealability after mounting, ensure that the sealing between two media.Front end pad 7 forms tube bank through welding by fixing for fin tube relative position, pad 7 has the groove of about 3mm, cuts off pad 7 after welding along groove, eliminates the impact of concentrating because welding the stress that causes.Rear end pad 7 is welded direct on end cap flange 8, forms with end cap 9 the cooling sap cavity closed, and cooling sap cavity makes cooling liquid in cooler core form U-shaped circulation.
Cooled pressurized air by tube bank, the internal surface of body and outer surface all have passed through the long-pending process of enlarged surface, add the area that fluid thermal exchanges.Tube cavity is cooling liquid, and outside is high-temperature gas, and the pipeline inner and outer surface by increasing surface area in the process of flowing carries out effective exchange heat.Fin body is compared with light pipe, and have larger surface area in the situation consuming metallic material identical, thicker wall thickness, improves heat-transfer coefficient, and heat-transfer effect is improved.And fin structure is not easy to be corroded and breakage, service life is long.The cooling liquid inlet of the utility model cooler core and cooling liquid outlet structure at one end, is convenient to arrange the cooling liquid turnover body connecting cooler like this.
The utility model can pass through without the technical characteristics described or adopt existing techniques in realizing; do not repeat them here; certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing; the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
