Abstract
The utility model discloses the two mainboard of a kind of automotive heat exchanger piercing and flanging formula reverse under punching, comprise the composite structure that mainboard and lower mainboard are combined, upper mainboard is plate stamping hole structure, upper mainboard has upper mainboard punching, lower mainboard has reverse piercing and flanging, convex to form short tube after lower mainboard piercing and flanging, the exterior edge face of upper mainboard and the inner side surface of lower mainboard closely cooperate.The utility model improves mainboard and heat dissipating pipe seam area, has carried out local strengthening, improve structural strength to the nearly mainboard position of heat dissipating pipe.
Description
Technical field
The utility model relates to a kind of heat-exchanger rig, particularly relates 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 purpose of this utility model is: avoid prior art Problems existing, provides the automotive heat exchanger piercing and flanging formula reverse under punching that a kind of structural strength is high two mainboard.
The technical solution of the utility model is: a kind of automotive heat exchanger two mainboard of piercing and flanging formula reverse under punching, comprise the composite structure that mainboard and lower mainboard are combined, upper mainboard is plate stamping hole structure, upper mainboard has upper mainboard punching, lower mainboard has reverse piercing and flanging, convex to form short tube after lower mainboard piercing and flanging, the exterior edge face of upper mainboard and the inner side surface of lower mainboard closely cooperate.
Further, chamfering is provided with inside the lower end mouth of short tube.
The beneficial effects of the utility model are: because the utility model have employed the composite structure that upper mainboard and lower mainboard combine, 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, decrease materials, reduce cost.The utility model heat exchanger 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 the utility model structure, 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 the utility model structure can be applicable to the applying working condition of multiple harshness.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the B-B sectional view of Fig. 1.
Embodiment
As can be seen from the B-B sectional view of the A-A sectional view of structural representation of the present utility model shown in Fig. 1, Fig. 2, Fig. 3, the utility model comprises the composite structure that mainboard and lower mainboard are combined, upper mainboard 511 is plate stamping hole structure, upper mainboard 511 has upper mainboard punching 512, lower mainboard 510 has reverse piercing and flanging, convex to form short tube 513 after lower mainboard piercing and flanging, inside the lower end mouth of short tube 513, be provided with chamfering 514.The exterior edge face of upper mainboard 511 and the inner side surface of lower mainboard 510 closely cooperate, and improve intensity.
The utility model is optimized design to mainboard, enhance the structural strength of key position, improve mainboard and heat dissipating pipe seam area, the heat dissipating pipe of automotive heat exchanger inserts after in short tube 513, it is coated that mainboard carries out part to heat dissipating pipe, local strengthening is carried out to the nearly mainboard position of heat dissipating pipe, heat exchanger overall construction intensity is got a promotion.
Above-described embodiment is also specific implementation form provided by the utility model; the utility model is not limited to above-mentioned embodiment; the improvement that all those skilled in the art carry out without creative work and distortion, all belong to protection domain of the present utility model.
