Description

The parallel stream oil cooler

Technical field

The utility model relates to a kind of motorcycle cooling unit, especially cools off the parallel stream oil cooler of motorcycle engine oil.

Background technique

In automobile, the motorcycle working procedure, the part heat that inflammable gas work done burning back produces is delivered on motor and other parts, cause the temperature of motor and other parts to raise, the harm of this kind temperature rising phenomenon is a lot, except the output power that reduces motor, also can quicken the wearing and tearing of part, even make between the part because of thermal expansion stuckly mutually etc., have a strong impact on the proper functioning of motorcycle engine.In the prior art, the method that solves motor and other part temperatures rising phenomenon mainly contains two kinds, a kind of is the mode that adopts natural heat dissipation, radiating fin is set on positions such as cylinder head, housing, the heat of cylinder head etc. is dispersed in the air, another is the mode that adopts cooler, recycles after the cooling water of high temperature in the cylinder head or the machine oil in the casing are passed into the cooling of lowering the temperature in water cooler or the oil cooler.The motorcycle cooler of prior art, initial structure is serpentine cooler (or claiming to crawl cooler), the cooling water of high temperature or machine oil feed (cooler inlet) from an end of cooler, through the cooling heat dissipation of serpentine cooling pipe, cooling water that temperature has been reduced or machine oil flow out (cooler outlet) from the other end of cooler at last; The advantage of this kind serpentine cooler is that cooling heat dissipation is effective, can bear big pressure, and its shortcoming is that flow is little, and the high-temperature cooling water that the unit time handles or the volume of machine oil are less, can not adapt to the needs of big discharge capacity, the demanding motorcycle of cooling effect.Another motorcycle cooler, it is stacked cooler, as name be called " a kind of water-cooling type radiator ", the patent No. is the disclosed radiator structure of Chinese utility model patent of ZL200420105201.X, to be that the lamination of one is overlapping form for hydroecium and heat dissipating pipe, and form with a lead welding of radiating fin, the multilayer inner blade is set in heat dissipating pipe, forms stacked cooler.The shortcoming of this kind structure is to bear big pressure difficulty, is easy to generate seepage under elevated pressures; And welding is difficult, welding job amount scrappage very big, product is high; The needs that can not adapt to big discharge capacity, the demanding motorcycle of cooling effect equally; The needs that especially can not adapt to the motorcycles such as the oil cooled sport car of employing high-pressure unit of big discharge capacity.

Summary of the invention

The utility model is at the above-mentioned deficiency of the motorcycle cooler of prior art, the parallel stream oil cooler that the high-temperature cooling water of provide a kind of good cooling results, can bear high pressure very, handling the unit time or the volume of machine oil be more, be fit to big discharge capacity high-pressure oil sport car needs.

The technical solution of the utility model: parallel stream oil cooler, comprise intake pipe, outlet pipe and radiating fin, it is characterized in that: between intake pipe and outlet pipe, be provided with the above harmonica-shaped tube of a row, inner chamber between intake pipe, harmonica-shaped tube and the outlet pipe is interconnected, and forms the fluid passage;

Further feature is: harmonica-shaped tube is one-time formed section bar, is provided with inner blade in it, and the fluid passage in the harmonica-shaped tube is separated;

Intake pipe and outlet pipe are the aluminium pipes.

Parallel stream oil cooler of the present utility model with respect to prior art, has following characteristics:

1, adopts harmonica-shaped tube and circular aluminium matter intake pipe, the structure that outlet pipe is welded to each other, make it can bear very high pressure, reach 80KG, can satisfy the needs of the motorcycle of various models fully through testing its " bursting pressure ".

2, the many harmonica-shaped tubes that be arranged in parallel cool to high-temperature cooling water or the machine oil that flows through simultaneously, and the high-temperature cooling water that the unit time handles or the volume of machine oil are several a lot.

3, be provided with inner blade in the harmonica-shaped tube, high-temperature cooling water or the machine oil that flows through is cooled, and heat transfer is arrived the outside, make it have better heat radiating effect; Be particularly suitable for the cooling heat dissipation needs of big discharge capacity oil injection type motor sport car.

4, significantly reduce the welding job amount, product percent of pass height, high working efficiency; Can effectively reduce the cost of cooler.

Embodiment

In Fig. 1,1-feed-water end, 2-waterexit end, 3-cooling pipe, 4-radiating fin;

Serpentine cooler shown in Figure 1, it is a kind of cooler of prior art, comprise feed-water end 1 and waterexit end 2, cooling pipe 3 is connected between feed-water end 1 and the waterexit end 2, cooling pipe 3 is the serpentine of many folding shapes and arranges, radiating fin 4 is distributed in the side of cooling pipe 3, plays the effect that increases heat diffusion area.The serpentine cooler of prior art, flow is little, and the high-temperature cooling water that the unit time handles or the volume of machine oil are less, can not adapt to the needs of big discharge capacity, the demanding motorcycle of cooling effect.

In Fig. 2,5-hydroecium, 7-heat dissipating pipe, 8-radiating fin; Wherein hydroecium 5 is overlapping the forming of lamination of one with heat dissipating pipe 7, and forms with 8 lead weldings of radiating fin; Multilayer inner blade etc. is set in heat dissipating pipe 7; Bear big pressure difficulty, under elevated pressures, be easy to generate seepage; And the welding job amount is very big, the welding difficult, the scrappage height of product.

In Fig. 3,10-intake pipe, 11-outlet pipe, 12-harmonica-shaped tube, 13-fluid passage, 14 1 radiating fin, 15-assembling set, 16-inner blade;

Parallel stream oil cooler of the present utility model comprises intake pipe 10 and outlet pipe 11, and intake pipe 10 enters the pipeline of cooler as fluid to be cooled, and outlet pipe 11 flows out the pipeline of cooler as the fluid that has cooled off.Between intake pipe 10 and outlet pipe 11, be provided with the above many rows harmonica-shaped tube 12 of a row, weld mutually with intake pipe 10 and outlet pipe 11 respectively at the two ends of harmonica-shaped tube 12, harmonica-shaped tube 12 is connected between intake pipe 10 and the outlet pipe 11 securely, hermetically, inner chamber between intake pipe 10, harmonica-shaped tube 12 and the outlet pipe 11 is interconnected, form fluid passage 13, flow for fluid to be cooled.At the side of harmonica-shaped tube 12, be provided with radiating fin 14, play the effect that increases heat diffusion area.Assembling set 15 is as parallel stream oil cooler of the present utility model being installed, is connected the assembly on other associated components.Harmonica-shaped tube 12 is a kind of one-time formed section bars, is provided with multilayer inner blade 16 in it, and the fluid passage 13 in the harmonica-shaped tube 12 is separated into multilayer, strengthens radiating effect.

Intake pipe 10 and outlet pipe 11 are selected aluminium for use, can weight reduction and reduce cost.Intake pipe 10 and outlet pipe 11 are pipes, can bear very high pressure.Inner blade 16 is except cooling to high-temperature cooling water or the machine oil that flows through, and heat transfer is arrived outside, have beyond the better heat radiating effect, 16 whiles of inner blade are as the reinforcement fin of harmonica-shaped tube 12, prevent that harmonica-shaped tube 12 is out of shape or ftractures, and makes harmonica-shaped tube 12 can bear very high pressure under very high pressure.

Because the inner blade 16 in the harmonica-shaped tube 12 is one-time formed, do not need welding, significantly reduce the welding job amount, product percent of pass height, product are made easily.
