Abstract
The invention discloses upper punching turnup type double main boards used for an automobile heat exchanger. The upper punching turnup type double main boards comprise a combined structure composed of the upper main board and the lower main board. The upper main board is provided with reverse punching turnups. Short pipes formed by the upper main board which is punched, flanged and protruded are inserted into main board holes of the lower main board. A plane I is in close contact with a plane II, wherein the plane I and the plane II are formed after the lower main board and the upper main board are combined. A gap is formed between a plane III and a plane IV. According to the upper punching turnup type double main boards, the welding area between the main boards and heat dissipation pipes is increased, local reinforcement is conducted on the portions, close to the main boards, of the heat dissipation pipes, and the 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 automotive heat exchanger piercing and flanging formula that a kind of structural strength is high two mainboard.
Technological scheme of the present invention 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 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;

Embodiment
As can be seen from the B-B sectional view of the A-A sectional view of structural representation of the present invention shown in Fig. 1, Fig. 2, Fig. 3, the present invention includes the composite structure that mainboard and lower mainboard are combined, upper mainboard 211 has reverse piercing and flanging, the mainboard hole 213 that the short tube 212 convexed to form after upper mainboard piercing and flanging inserts lower mainboard is inner, is provided with chamfering 214 inside the lower end mouth of short tube 212.The short tube 212 that upper mainboard 211 piercing and flanging is formed coordinates with lower mainboard hole 213, is provided with the plane to lower convexity between the short tube 212 that upper mainboard 211 liang is adjacent
215, be provided with the plane raised up between the mainboard hole 213 that lower mainboard 216 liang is adjacent
217, lower mainboard 216 combines back plane with upper mainboard 211
215 and plane
217 close contacts, improve structural strength.Two ends, lower mainboard hole 213 have plane
218, short tube 212 liang of short two ends have plane
219, lower mainboard 216 combines back plane with upper mainboard 211
218 and plane
there is between 219 the gap of distance for 1mm ~ 10mm, both saved material, and turn improved intensity.
The present invention 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 212, 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.
