Internal combustion engine is widely-used in fields such as heavy truck, heavy engineering machinery, big bus car or general-utility cars as a kind of dynamical power source.Internal combustion engine at work because the contacts fuel gas of parts such as cylinder, cylinder head, piston and valve and high temperature receives strong heating, mechanical temperature is very high, not only can cause parts intensity to reduce, and possibly produce very big 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 gets into cylinder reduce, and causes pinking, the malcombustion of pre-ignition equality etc.In order to guarantee normal, the operation reliably of internal combustion engine, must work under best temperature to keep internal combustion engine through cooler to these high temperature parts coolings.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 utilization of water-cooled cooler circulates, more effective than air cooling, when particularly being applied to powerful internal combustion engine such as general-utility car, heavy truck, heavy-duty machinery or big bus car.The core component of cooler is a 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 formation one row or many rows between the radiating tube and forms radiator core body.Following situation can appear in radiator working environment very severe: produce high-intensity vibration when 1, working; Produce very big 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 type situation causes; In the place of abominable working environment such as truck, engineering machinery and agricultural machinery, problems such as resistance to shock is not high, impact resistance is poor, reliability is not high, service life is short appear more easily particularly.

Summary of the invention

In order to overcome above-mentioned defective, the objective of the invention is: a kind of not only good heat dissipation effect is provided, and radiating tube is made up in the one-sided bending that intensity is largely increased.

Technical scheme of the present invention is: comprise the body that the heat radiation thin slice and the thin slice that dispels the heat are down combined; Has inside continuous bending under the A side direction of last heat radiation thin slice broad ways; Form the bending place I, the bending place I contacts with last heat radiation thin slice formation face, has inside continuous bending on the B side direction of following heat radiation thin slice broad ways; Form the bending place II; Bending place I and bending place II have the same number bending segment, and the bending place II contact with following heat radiation thin slice formation face, on dispel the heat B lateral buckling place's II and going up of the A lateral buckling place's I of thin slice and the thin slice that dispels the heat down between the heat radiation thin slice, down dispel the heat that soldering group lumps together the formation body between the thin slice.

Said going up on heat radiation thin slice and the following heat radiation thin slice has relative depression reinforcement along its length, and reinforcement links together up and down.

The invention has the beneficial effects as follows: the present invention is through changing the shape of body both sides; Both sides cause through the variable thickness that folding mode obtains the radiating tube different parts, form section thickness and do not wait, that is to say through change section thickness obtain high strength and with the unification of high heat dispersion; The area thickness of middle heat radiation is constant; Make radiating tube keep good performance of heat dissipation,, formed bigger wall thickness simultaneously requiring the higher both sides of mechanical performance; Thereby obtain the significantly lifting of each item mechanical performance; Anti-ly shake, tension, performance such as high pressure resistant, shock-resistant all have and significantly improve, and when increasing various mechanical performances, the part that middle wall thickness is thin still keeps good heat dispersion.The present invention can be widely used in cooling systems such as motor vehicle, engineering machinery and farm machinery, change exchange system.
