Abstract

The utility model discloses a radiating tube with two foldable sides. The radiating tube with two foldable sides comprises a flat tube body which is provided with an upper radiating sheet and a lower radiating sheet. The flat tube is provided with continuous folding segments arranged vertically at two sides along the width direction. The continuous folding segments and upper and lower radiating sheets form surface contact so that the thicknesses of different portions of the radiating tube are different. The radiating effect is good and the strength is greatly improved.

Description

The collapsible radiating tube in both sides

Technical field

The utility model belongs to and changes the interchanger technical field, especially relates to the collapsible radiating tube in a kind of both sides.

Background technology

Internal combustion engine is widely used in fields such as heavy truck, heavy engineering machinery, bus or general-utility cars as a kind of dynamical power source.Internal combustion engine at work because the contacts fuel gas of the parts such as cylinder, cylinder head, piston and valve and high temperature is subject to strong heating, mechanical temperature is very high, not only can cause the parts strength decreased, and may produce very large thermal stress, makes the parts damage.High temperature also can destroy the lubricating oil film on the cylinder wall, makes oil ageing rotten, so that piston, piston ring and cylinder jacket heavy wear, bites and adhere.In addition, too high temperature also can make the atmospheric density that enters cylinder reduce, and causes pinking, the malcombustion of pre-ignition equation etc.In order to guarantee normal, the reliably operation of internal combustion engine, must by cooler to these high temperature parts coolings, work under the temperature of the best to keep internal combustion engine.Cooler is by air-cooled two kinds of type of cooling separatory cold-peace, and the employing air is air-cooled or air-cooled type cooler as being called of cooling medium.Adopt liquid as medium be called the liquid-cooled cooler, general liquid-cooled cooler adopts water as cooling medium.The parts of the cooling down high-temperature that the water-cooled cooler utilization circulates, more effective than wind cooling, when particularly being applied to the powerful internal combustion engine such as general-utility car, heavy truck, heavy-duty machinery or bus.The core component of cooler is radiator core body, and radiating tube is the critical piece of radiator core body, and it is determining the quality index such as structural strength, sealing property, heat dispersion of radiator.The radiating tube that present traditional water-cooling type radiator uses generally is single channel or multi-channel cooling pipe, and the radiating tube cross section is circular, oval or square rounding, is spaced between the radiating tube and forms a row or multi-row composition radiator core body.Following situation can appear in radiator working environment very severe: produce high-intensity vibration when 1, working; Produce very large pulling force when 2, jolting, to particularly connecting portion compression or the stretching energetically of each position of product; 3, high temperature and each several part temperature are different, and the each several part that causes expands different and stress difference that produce.The radiator that existing market is used has a large amount of because the leakage that this class situation causes, particularly in the place of the abominable working environment such as truck, engineering machinery and agricultural machinery, easier the problems such as resistance to shock is not high, impact resistance is poor, reliability is not high, service life is short appear.

Summary of the invention

In order to overcome defects, the purpose of this utility model is: a kind of not only good heat dissipation effect is provided, and the collapsible radiating tube in both sides that is largely increased of intensity.

The technical solution of the utility model is: comprise flat body, flat body has upper heat radiation thin slice and lower heat radiation thin slice, the both sides of flat body broad ways have continuous folded section setting up and down, continuously folded section with dispel the heat up and down that formation face contacts between the thin slice.

Has along its length relative depression reinforcement on described upper heat radiation thin slice and the lower heat radiation thin slice.

The beneficial effects of the utility model are: the utility model is by changing the shape of body both sides, both sides cause by the variable thickness that folding mode obtains the radiating tube different parts, Formation cross-section thickness does not wait, that is to say by change section thickness obtain high strength and with the unification of high heat dispersion, the area thickness of middle heat radiation is constant, so that radiating tube keeps good heat dispersion, simultaneously requiring the higher both sides of mechanical performance, formed larger wall thickness, thereby obtain the significantly lifting of every mechanical performance, anti-shaking, tension, high pressure resistant, the performance such as shock-resistant has significantly and improves, and when increasing various mechanical performances, the part that middle wall thickness is thinner still keeps good heat dispersion.The utility model can be widely used in the cooling systems such as motor vehicle, engineering machinery and farm machinery, change exchange system.

The specific embodiment

Can find out from the section of structure of the collapsible radiating tube in the utility model shown in Figure 1 both sides, the utility model is flat body, flat body has upper heat radiation thin slice 2 and lower heat radiation thin slice 3, the both sides of flat body broad ways have continuous folded section I 1 setting up and down, continuous folded section II 4, collapsible 3 to 5 sections of each continuous folded section, the hop count of the continuous folded section in both sides is identical.Continuously between the folded section and continuously folded section contact by flattening formation face between the thin slice with dispelling the heat up and down so that the channel seal of inside and form body, thereby make the thickness increase of flat body both sides.The utility model by change section thickness obtain high strength and with the unification of high heat dispersion, the area thickness of middle heat radiation is constant, so that radiating tube keeps good heat dispersion, simultaneously requiring the higher both sides of mechanical performance, and formed larger wall thickness, make anti-ly shake, tension, the performance such as high pressure resistant, shock-resistant increase substantially.The utility model can adopt the heat-transfer matcrials such as aluminium sheet, copper coin, corrosion resistant plate, can adopt the modes such as soldering or ratio-frequency welding during welding.The utility model and fins set are fitted together, and form heat exchanger after welding through soldering, vacuum welding, ratio-frequency welding or other modes.

Fig. 2 is the schematic diagram of the another kind of embodiment of the collapsible radiating tube in the utility model both sides, the version of both sides is identical with Fig. 1, simultaneously on upper heat radiation thin slice and lower heat radiation thin slice, have along its length relative depression reinforcement 5, depression reinforcement 5 up and down lays respectively at the centre position of the sheet width direction of dispelling the heat up and down.Certainly, the depression reinforcement also can be arranged on other position of width, can be a reinforcement, also can be two reinforcements or three reinforcements, and reinforcement can have certain width.

Should be pointed out that the utility model can also carry out some improvement, all those skilled in the art are without the resulting improvement of creative work, all within claim protection domain of the present utility model.
