Description

Two-stage cooling intercooler

Technical field

The utility model relates to a kind of pressurized air heat-exchange device, and the heat exchanger that specifically a kind of water and cooling air carry out the two-stage cooling to pressurized air is called for short two-stage cooling intercooler.

Background technique

At present, the intercooler that we use always has two kinds: a kind of is that water comes charge air cooling, and another kind is to come charge air cooling with cooling air.

On marine engine, because the source of cooling water is not a problem, water comes charge air cooling to obtain extensive use on marine engine; Equally, owing to there is not the source of low-temperature cooling water on the automobile, and the engine cycles coolant-temperature gage is higher, can only be cooled to 80～90 ℃ to pressurized air, therefore water comes the application of charge air cooling on automobile to be subjected to great restriction, and opposite air-to-air intercooled aluminum intercooler obtains application more and more widely on automobile.

In order to reduce the discharging of motor, improve the specific efficiency of motor, motor high pressure-charging The Application of Technology will be day by day extensive.Along with increasing of engine booster ratio, the outlet temperature of pressurized machine, promptly the inlet temperature of intercooler can be more and more higher, and when the inlet temperature of intercooler during greater than a threshold value, high temperature creep will take place in aluminium, and the reliability of the absolutely empty intercooler of aluminum will be subjected to severe challenge; On the other hand, more and more higher along with the engine booster ratio, the heat radiation load of absolutely empty intercooler will more and more higher also, and the volume of absolutely empty intercooler is also with increasing, and is very unfavorable to the car load layout.

Summary of the invention

The purpose of this utility model provides a kind of two-stage cooling intercooler, comes the pressurized air of cooling down high-temperature with it, has improved the shortcoming of above-mentioned existing intercooler.

The technological scheme that the utility model adopted is to achieve the above object of the invention: a kind of two-stage cooling intercooler, comprise secondary coolers, and near the suction tude of secondary coolers, set up the one-level cooler.

Described one-level cooler is installed in the suction chamber of secondary coolers.

Described one-level cooler is the fine-type stainless steel plate structure, and secondary coolers is aluminium plate-fin structure or aluminum pipe belt structure.

Described one-level cooler comprises fuse two, and intake pipe and outlet pipe are housed on the fuse two; Described secondary coolers comprises fuse one, and fuse is held one by one discharge chamber is housed, and steam outlet pipe is arranged on the discharge chamber, and fuse one the other end is equipped with air flue, suction chamber, is installed into tracheae on the suction chamber.

Described one-level cooler is spirally connected by bolt, plain cushion, spring washer and sealing gasket, or is linked together by press seal structure and secondary coolers, and perhaps two-stage cooler directly welds together.

The utility model principle is exactly that circulating water (or other water sources) with motor and cooling air carry out the two-stage cooling to pressurized air: with the circulating water (or other water sources) of motor the pressurized air one-level is cooled to below the temperature (200 ℃) that aluminium can bear earlier, pressurized air is cooled in the temperature range of motor regulation with cooling air again, the advantage of two-stage cooling intercooler: the one-level cooler has adopted the fine-type stainless steel plate structure, improved the temperature applicable range of intercooler, guarantee intercooler and high-temperature gas Long contact time and creep does not take place, because the one-level cooler adopts water to be used as cooling medium, perfect heat-dissipating, dwindled the volume of product greatly, and the one-level cooler is to be arranged in dexterously in the suction chamber of secondary coolers, improve the compactedness of product, made things convenient for car load to arrange; Secondary coolers adopts aluminium plate-fin structure or aluminum pipe belt structure, guarantees the bearing capacity of intercooler, guarantees that product is unlikely to lose efficacy under the high pressure condition.

Embodiment

Embodiment one:

With reference to Fig. 1-3, two-stage cooling intercooler mainly is made up of secondary coolers and one-level coolers of being loaded in its suction chamber 10.The one-level cooler adopts the fine-type stainless steel plate structure, and it mainly comprises fuse 24, is installed into water pipe 9 and outlet pipe 8 on the fuse 24, connects sealing by welding between them, and wherein fuse 24 is to weld together by high temperature brazing; Secondary coolers adopts aluminium plate-fin structure or aluminum pipe belt structure, it mainly comprises fuse 1, fuse one 2 one ends are equipped with discharge chamber 1, steam outlet pipe is arranged on the discharge chamber, fuse one 2 the other ends are equipped with air flue 3, suction chamber 10, be installed into tracheae 7 on the suction chamber 10, the material of discharge chamber 10 and air flue 3 all is a cast aluminium, connect sealing by welding between them, because the one-level cooler has adopted different materials with secondary coolers, can not be linked together by welding mutually, they connect sealing (referring to Fig. 3) by bolt 5 press seal structures.
