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 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, comprise the composite structure that mainboard and lower mainboard are combined, upper mainboard has reverse piercing and flanging, the mainboard hole that the short tube convexed to form after upper mainboard piercing and flanging inserts lower mainboard is inner, the short tube that upper mainboard piercing and flanging is formed coordinates with lower mainboard hole, is provided with the plane to lower convexity between the short tube that upper mainboard two is adjacent
, between the mainboard hole that lower mainboard two is adjacent, be provided with the plane raised up
, lower mainboard and upper mainboard combine back plane
with plane
close contact, two ends, lower mainboard hole have plane
, short tube two short two ends have plane
, lower mainboard and upper mainboard combine back plane
with plane
between there is gap.
Further, lower mainboard and upper mainboard combine back plane
with plane
between there is distance for the gap of 1mm ~ 10mm.
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, owing to there is gap between upper and lower mainboard, 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.
