Description
Technical field
The present invention relates to a kind of radiator, more particularly, to a kind of double wave inner fin structure charge air cooler.
Background technology
With the development of auto industry, in order to improve power per liter, reaching, which reduces oil consumption, reduces discharge, and turbocharger is wide
General application due to the configuration of turbocharger, just be unable to do without charger-air cooler, i.e. charge air cooler（CAC）, turbocharger with
Charge air cooler matches.There is the material wall thickness that the problem of maximum is mainboard and heat-dissipating pipe for the conventional structure of existing charge air cooler
Differ greatly, be caused by vibration, thermal shock, pressure alternation impact and generate heat exchanger failure, cause automobile engine work
Make that powerless, discharge is exceeded, oil consumption rising, braking effect is poor, can not switch situations such as driving in time more, so as to influence to work normally.
Mainboard may usually occur in existing conventional techniques or the special phenomenon of rupture of transverse breakage occurs in collector plate nearside heat-dissipating pipe, should
Kind of failure is caused since pressure stresses or thermal stress can not discharge in time, and main board material thickness is big more than heat dissipation tube thickness,
The very big position of rigid and the engaging portion of the relatively low heat-dissipating pipe of rigid is caused low-intensity component failure occur.With automobile
Industrial expansion, the continuous promotion of engine power, the operating pressure of engine-cooling system are continuously improved, turbocharger
The continuous promotion with turbo charge system performance is generally used, the trend to double also occur in 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, this requires heat exchanger into
Upgrading, the structure updating of row material are sent out although the application of high-strength material and the increase of material thickness can extend with high-performance
The matching usage time of motivation, but can change existing production technology, increase new tooling, mold and new equipment, from
And it increases input, increase cost.
Invention content
The purpose of the present invention is：There is provided a kind of structural strength high double wave inner fin structure charge air cooler.
The technical scheme is that：A kind of double wave inner fin structure charge air cooler, including first end cooling medium storage room,
It is scattered between second end cooling medium storage room corresponding with first end cooling medium storage room, both ends cooling medium storage room
Hot core；Radiating core by both ends mainboard, connect both ends mainboard heat-dissipating pipe, with the spaced apart radiating fin of heat-dissipating pipe and
Side plate positioned at both sides forms, and is equipped with double wave structure inner fin inside heat-dissipating pipe, double wave structure inner fin include upper inner fin, under
Inner fin and the plain film at intermediate position are connect at plain film and the wave crest of upper inner fin and lower inner fin, upper inner fin and lower interior wing
The outmost wave in piece both ends matches to form two-layer composite with R in heat-dissipating pipe quadrangle, the outer end of outmost wave to
Inside tilts, and the both ends of plain film have unilateral or both sides flange, and flange matches to form two-layer compound with the short side of heat-dissipating pipe
Structure, the outer end of flange internally tilt.
Further, the left and right of upper inner fin and lower inner fin is in unsymmetric structure.
Further, lower inner fin is to rotate to obtain through 180 degree by upper inner fin.
Further, the height that the outer end of the outmost wave I of upper inner fin and lower inner fin both ends internally tilts
The minimum I thickness t1 of 0.5mm+ waves of H10.
Further, the minimum 0.5mm+ flange thickness t2 of height H13, H14 that the outer end of flange internally tilts.
Further, upper inner fin and lower inner fin are equipped with shutter.
Further, upper inner fin and one kind that lower inner fin is rectangle wave structure, sinusoidal configuration or triangle wave structure.
The beneficial effects of the invention are as follows：The present invention inside heat-dissipating pipe due to being equipped with double wave structure inner fin, to charge air cooler
Weakness carries out local strengthening the most, and charge air cooler overall structure is caused to be strengthened, and is effectively improved charge air cooler and height is warmed
The endurance quality of stress, high pressure stress.1st, since double wave structure inner fin includes upper inner fin, lower inner fin and intermediate position
Plain film, effectively reduces the wave height of inner fin, and the wave height of inner fin is reduced to originally（Thin inner fin）The half of height, support
Intensity and tension intensity are than original（Thin inner fin）Structure is enhanced about more than once so that the structural strength of inner fin is carried
It is high.2nd, double wave structure inner fin is effectively strengthened at position-heat-dissipating pipe quadrangle R that heat-dissipating pipe is weaker and stress is concentrated the most,
It is double-walled construction that inside, which is equipped at the heat-dissipating pipe quadrangle R of double wave structure inner fin, after weld formation as an entirety, is equivalent to
Material thickness at the R of heat-dissipating pipe quadrangle is increased, is significantly reduced with thickness disparity of the mainboard at this, obtains the Weld strength at this
Greatly improve.3rd, since the plain film both ends at intermediate position have unilateral or both sides flange, the short side phase of flange and heat-dissipating pipe
Two-layer composite is cooperatively formed, also greatly improves the structural strength of heat-dissipating pipe.The present invention is not changing existing processing work
On the basis of skill, associated components are locally optimized, strengthen critical component partial structurtes intensity or make local welding
Intensity strengthen, material cost it is constant or slightly reduce under the premise of so that charge air cooler overall construction intensity improve a grade.
Charge air cooler high temperature resistant of the present invention can reach 260 DEG C or more, and compression resistance can reach more than 2.0MPa（Mill run high temperature resistant is 160
DEG C, compression resistance 1.1MPa）, the resistance to temperature shock and compression shock of product are greatly improved, puies forward the service life of product
More than doubling, the applying working condition of a variety of harshnesses can be suitable for using the product of structure of the present invention.
