Description
Technical field
The present invention relates to a kind of heat-exchanger rig more particularly to a kind of double mainboard structure automotive heat exchangers.
Background technology
In automobile normal course of operation, various heat exchangers are be unable to do without, the radiator to engine water jacket heat dissipation is to ensure hair
Motivation long-time stable is in certain temperature range, continuous lasting normal work, keeps the working efficiency highest of engine.With
The development of auto industry, the continuous promotion of HP, hp/litre, the operating pressure of engine-cooling system are continuously improved, and turbine increases
Also there is the trend to double in the generally use of depressor and the continuous promotion of turbo charge system performance, the system pressure and temperature,
To adapt to the requirement of higher temperature, higher pressure, usual heat exchanger cannot meet the needs of higher engine.Heat exchange mostly now
Device there are one it is similary the problem of, that is, the material wall thickness of mainboard or collector plate and heat-dissipating pipe differs greatly, and is caused by
Vibration, thermal shock, pressure alternation impact and generate heat exchanger failure, cause automobile engine powerless in work, discharge exceeded, oily
Consumption rises, braking effect is poor, can not switch situations such as driving in time more, so as to influence to work normally.Existing conventional techniques can be usually
There is phenomena such as mainboard deformation, cracking, be since charge air cooler internal system pressure is continuously improved, made under high temperature, high-pressure situations
Drastically decline into main board material intensity and fail.
Invention content
The purpose of the present invention is：Problem of the existing technology is avoided, provides a kind of structural strength high automotive heat exchanger
Use the double mainboards of reversed punched holes type under reversed piercing and flanging.
The technical scheme is that：A kind of automotive heat exchanger uses the double mainboards of reversed punched holes type under reversed piercing and flanging,
Including the composite construction that upper mainboard and lower mainboard are combined, upper mainboard has reversed piercing and flanging, and lower mainboard has reversed
Punching, the short tube that upper mainboard piercing and flanging rear projection is formed are inserted into inside the mainboard hole of lower mainboard, and short tube coordinates with lower mainboard hole,
Downwardly convex plane is equipped between the adjacent short tube of upper mainboard two, it is equipped with what is raised up between the adjacent mainboard hole of lower mainboard two
Plane, plane after lower mainboard is combined with upper mainboardWith planeIt is in close contact, lower mainboard hole both ends have plane, short tube
Two short face both ends have plane, plane after lower mainboard is combined with upper mainboardWith planeBetween have gap.
Further, plane after lower mainboard is combined with upper mainboardWith planeBetween there is distance for 1mm~10mm
Gap.
Further, it is equipped with chamfering on the inside of the lower port of short tube.
The beneficial effects of the invention are as follows：Since present invention employs the composite junctions that upper mainboard and lower mainboard are combined
Structure, the structural strength of mainboard itself are improved, meanwhile, increase the contact surface of mainboard and heat-dissipating pipe, improve mainboard with dissipating
Heat pipe soldering area, makes local weld strength be strengthened, and mainboard is closely main to heat-dissipating pipe after heat-dissipating pipe carries out part cladding
Plate portion position has carried out local strengthening.While requirements at the higher level engine is met, since there are gaps between upper and lower mainboard, reduce
Materials, reduce cost.Heat exchanging device of the present invention weakness the most carries out local strengthening, and mainboard is locally optimized and is set
Meter strengthens key position partial structurtes intensity, heat exchanger overall construction intensity is made to get a promotion.By taking charge air cooler as an example, this is used
The charge air cooler of inventive structure, high temperature resistant can reach 260 DEG C or more, and compression resistance can reach more than 2.0MPa（Mill run high temperature resistant
It is 160 DEG C, compression resistance 1.1MPa）, the resistance to temperature shock and compression shock of product are greatly improved, make product uses the longevity
Life is enhanced about more than once, and can be suitable for the applying working condition of a variety of harshnesses using the product of structure of the present invention.

Specific embodiment
This is can be seen that from the B-B sectional views of structure diagram of the invention shown in Fig. 1, the A-A sectional views of Fig. 2, Fig. 3
Invention includes the composite construction that mainboard and lower mainboard are combined, and upper mainboard 311 has reversed piercing and flanging, lower mainboard
310 have reversed punching, and the short tube 312 that upper mainboard piercing and flanging rear projection is formed is inserted into inside the mainboard hole 313 of lower mainboard, short
Chamfering 314 is equipped on the inside of the lower port of pipe 312.Short tube 312 coordinates with lower mainboard hole 313, upper 311 liang of adjacent short tubes of mainboard
Downwardly convex plane is equipped between 312315, the plane to raise up is equipped between the adjacent mainboard hole 313 of lower 316 liang of mainboard
317, plane after lower mainboard 316 is combined with upper mainboard 311315 and plane317 are in close contact, and improve structural strength.Lower master
313 both ends of plate hole have plane318,312 liang of short face both ends of short tube have plane319, lower mainboard 316 and upper mainboard 311
Plane after combination318 and planeThe gap that there is distance to be 1mm~10mm between 319, has saved material, and improve
Intensity.
