Embodiment

For the purpose, technological scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

The utility model embodiment's main technical schemes is, mainly the heat dissipating pipe to intercooler partly improves, and in the inside of this heat dissipating pipe spoiler is set, and the tube wall of described spoiler and described heat dissipating pipe is welded to connect.This spoiler can be changed the form of air ventilation better with respect to the sheet stiffening rib in the prior art drawn tube, and air-flow is changed to flow-disturbing, has increased the exposure level of hot gas and radiating pipe wall, has improved the efficient of heat exchange, and then has improved radiating effect.Below by the drawings and specific embodiments, the technical solution of the utility model is described in further detail.

Fig. 2 is the utility model intercooler embodiment's a plan view, and Fig. 3 is the utility model intercooler embodiment's a plan view, and Fig. 4 is the utility model intercooler embodiment's a left view.Shown in Fig. 2～4, present embodiment is that the intercooler with left and right sides air chamber structure form is that example describes, and is applicable to the improvement structure of present embodiment too for other forms of intercoolers such as air chamber structure forms up and down.

This intercooler can comprise first air chamber 12, second air chamber 13, main leaf 14, core body 15 and fixed support 16.Wherein, first air chamber 12 can be communicated with pressurized machine, is used to receive the air after the pressurized machine supercharging; Second air chamber 13 can be communicated with engine intake, is used for the pressurized air after the cooling is delivered to motor.Be provided with main leaf 14 and core body 15 between first air chamber 12 and second air chamber 13, wherein, the quantity of main leaf 14 can be two, and these two main leaves 14 lay respectively at the connecting part of the core body 15 and first air chamber 12, and the connecting part of the core body 15 and second air chamber 13.Core body 15 can be combined by a plurality of heat dissipating pipes 17 and a plurality of heat-radiation belt 18, and heat-radiation belt 18 is between two adjacent heat dissipating pipes 17, and the air heat that is used for heat dissipating pipe 17 is absorbed is to external diffusion.Main leaf 14 is provided with a plurality of spliced eyes, be used for pegging graft and connect with a plurality of heat dissipating pipes 17 of core body 15, make to be communicated with between air chamber and the heat dissipating pipe that pressurized air can directly enter heat dissipating pipe after entering first air chamber 12, can directly enter second air chamber 13 after coming out from heat dissipating pipe.Fixed support 16 can be used for this intercooler is connected with the miscellaneous part of automobile.

The main distinction point of the intercooler structure of present embodiment and the intercooler structure of prior art is, heat dissipating pipe 17 is improved.In the heat dissipating pipe 17 of present embodiment the sheet stiffening rib can also be set, but be set to spoiler, for example, can be the waveform spoiler.Fig. 5 is the structural representation of the heat dissipating pipe among the utility model intercooler embodiment, as shown in Figure 5, spoiler in this heat dissipating pipe is an example with the waveform spoiler, built-in waveform spoiler 21 is arranged in this heat dissipating pipe, and this waveform spoiler 21 can adopt welding manner and radiating pipe wall 19 to be connected as one.This waveform spoiler 21 is with respect to the sheet stiffening rib in the prior art drawn tube, can change the form of air ventilation better, air-flow is changed to flow-disturbing, increase the exposure level of hot gas and radiating pipe wall 19, improve the efficient of heat exchange, and then improved radiating effect.

On this basis, can also do further optimization to waveform spoiler 21.Because according to practical experience,, generally have step-down and limit, for example 10KPa owing to when cool off, can reduce air pressure inevitably for pressurized air.Fig. 6 is the structural representation of the waveform spoiler embodiment among Fig. 5, as shown in Figure 6, can on this waveform spoiler 21 a plurality of windowing be set, and this is windowed and be a plurality of openings 20 that are provided with on waveform spoiler 21.The flow-disturbing effect is strengthened in this further cutting steam of opening 20, increases the area of contact of hot gas and waveform spoiler 21, improves radiating efficiency; And these a plurality of openings 20 are crisscross arranged on waveform spoiler 21, and effects such as the flow-disturbing in the time of can increasing hot air and flow, exchange cutting improve radiating effect to greatest extent.The form of windowing of these a plurality of openings 20 can also make that air-flow is unimpeded, reduces the resistance for air.Sheet reinforcing rib structure in the drawn tube of the prior art is to such an extent as to because the restriction stiffening rib of technology can not too carefully cause the increase of heat dissipating pipe internal resistance, the above-mentioned fenestration of present embodiment can play the effect that reduces and regulate the heat dissipating pipe internal resistance with respect to this.

In concrete the enforcement, can adjust that to optimize windowing on the waveform spoiler 21 be the angle of opening 20, enable cutting steam better, in heat radiation with reduce all to reach optimum aspect the resistance.For example, this angle of windowing can be set to 40 degree or 45 degree.

Further, the intercooler structure of present embodiment has also been carried out improvement on the other hand to heat dissipating pipe 17.Concrete, drawn tube of the prior art is that aluminium bar processes through cold-drawing technology, the too thin words of wall thickness of Cold Drawing Process control, in the process that can occur extend tube wall portal or pipe wall thickness inhomogeneous, and owing to be subjected to mould and processing technology influence, drawn tube is prone to the phenomenon of wall unevenness; And the heat dissipating pipe 17 in the present embodiment is a ratio-frequency welded tube, be with material to be welded through the high frequency tube producer uniformly by very thin, thickness, with respect to drawn tube of the prior art, its wall thickness is even, no subsurface defect, and can continue to bear the above pressure of 4.0MPa and can not destroy.In addition, the wall thickness of this heat dissipating pipe for example can be 0.45mm, can be so that the in light weight and weight of heat dissipating pipe be stable, and the weight of corresponding core body 15 also can reduce, and the core body of same ratio-frequency welded tube is lighter by about 1/3 than the core body of drawn tube; And the weight of corresponding whole intercooler assembly also can correspondingly reduce, and is more conducive to the lightweight of car load under the prerequisite of guaranteed performance.

The intercooler of present embodiment is taken over by heat dissipating pipe being made highfrequency welding, makes that the wall thickness of pipe is even, does not have subsurface defect; And, strengthened radiating effect by built-in waveform spoiler in this pipe.

It should be noted that at last: above embodiment only in order to the explanation the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technological scheme that aforementioned each embodiment put down in writing, and perhaps part technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment's technological scheme of the utility model.
