Abstract
The invention discloses a double-mainboard assembly provided with provided with a reversely punched and flanged upper mainboard and a punched and flanged lower mainboard for an automobile heat exchanger. The upper mainboard protrudes after being punched and flanged, so that short pipes I are formed. The lower mainboard protrudes after being punched and flanged, so that short pipes II are formed. A reinforcing rib which protrudes upwards is arranged between every two adjacent short pipes I of the upper mainboard, wherein the cross section of the reinforcing rib is semicircular. A communication pipe is formed through the short pipes I and the short pipes II after the upper mainboard and the lower mainboard are combined. According to the double-mainboard assembly provided with provided with the reversely punched and flanged upper mainboard and the punched and flanged lower mainboard for the automobile heat exchanger, the welding area of the mainboards and a heat dissipation pipe is increased, the portions, close to the mainboards, of the heat dissipation pipe are locally reinforced, and structural strength is improved.
Description
Technical field
The present invention relates to a kind of heat-exchanger rig, particularly relate to a kind of two mainboard structure automotive heat exchanger.
Background technique
In automobile normal course of operation, be unable to do without various heat exchanger, be ensure that the engine long time is stabilized in certain temperature range to the radiator of engine water jacket heat radiation, continue normal work continuously, keep the working efficiency of motor the highest.Along with the development of automotive industry, the continuous lifting of HP, hp/litre, the working pressure of engine-cooling system improves constantly, the generally use of turbosupercharger, with the continuous lifting of turbo charge system performance, also there is the trend doubled in this system pressure and temperature, for adapting to the requirement of higher temperature, more high pressure, usual heat exchanger can not meet the demand of more high-engine.All there is a same problem in present heat exchanger mostly, that is exactly that the material wall thickness of mainboard or collector plate and heat dissipating pipe differs greatly, cause due to vibration, thermal shock, pressure change impacts and produce heat exchanger failure, cause motor car engine powerless in work, discharge exceeds standard, oil consumption rising, braking effect are poor, cannot switch situations such as driving in time more, thus impact normally works.Usually can there is the phenomenons such as mainboard distortion, cracking in existing routine techniques, be improve constantly due to intercooler internal system pressure, cause main board material intensity sharply decline and lost efficacy under high temperature, high-pressure situations.
Summary of the invention
The object of the invention is: avoid prior art Problems existing, provide the high automotive heat exchanger of a kind of structural strength to use the two mainboard of piercing and flanging formula under reverse piercing and flanging.
Technological scheme of the present invention is: a kind of automotive heat exchanger uses the two mainboard of piercing and flanging formula under reverse piercing and flanging, comprise the composite structure that mainboard and lower mainboard are combined, lower mainboard has piercing and flanging, upper mainboard has reverse piercing and flanging, short tube I is convexed to form after upper mainboard piercing and flanging, short tube II is convexed to form after lower mainboard piercing and flanging, the stiffening rib of the cross section semicircular in shape that raises up is provided with between the short tube I that upper mainboard two is adjacent, gap is formed between the flange of semicircular stiffening rib and lower mainboard, upper mainboard and the rear short tube I and short tube II of lower mainboard combination form a phase siphunculus.
Further, upper mainboard and the rear short tube II of lower mainboard combination insert a short tube I inside composition phase siphunculus.
Further, upper mainboard and the rear short tube I of lower mainboard combination insert a short tube II inside composition phase siphunculus.Chamfering is provided with inside the lower end mouth of short tube I.
The invention has the beneficial effects as follows: owing to present invention employs the composite structure that upper mainboard and lower mainboard are combined, the structural strength of mainboard self is improved, simultaneously, the surface of contact of mainboard and heat dissipating pipe is increased, improve mainboard and heat dissipating pipe seam area, make local weld strength strengthened, mainboard to heat dissipating pipe carry out part coated after, local strengthening has been carried out to the nearly mainboard position of heat dissipating pipe.While meeting requirements at the higher level motor, owing to there is gap between upper and lower mainboard, decrease materials, reduce cost.Heat exchanger of the present invention the most weakness carries out local strengthening, is optimized design to mainboard local, strengthens key position partial structurtes intensity, heat exchanger overall construction intensity is got a promotion.For intercooler, use the intercooler of structure of the present invention, high temperature resistantly reach more than 260 DEG C, compression resistance can reach more than 2.0MPa, and (mill run is high temperature resistant is 160 DEG C, compression resistance is 1.1MPa), drastically increase resistance to temperature shock and the compression shock of product, the working life of product is enhanced about more than once, use the product of structure of the present invention can be applicable to the applying working condition of multiple harshness.
