Description

The composite engine radiator

Technical field

The present invention relates to the heat radiation cooling system of automobile, two engineering machinery, generator set, particularly the structure of engine-cooling system specifically is a kind of thin box-like engine radiator.

Background technique

Radiator and intercooler are indispensable vitals in the engine-cooling system in the modern engine work, and for fear of engine overheat, the component (cylinder sleeve, cylinder cap, valve etc.) around the firing chamber must carry out suitable cooling.In order to guarantee cooling effect, engine-cooling system generally is made up of radiator, thermostat, water pump, cylinder block passage, cylinder cap water channel, fan etc.Radiator is responsible for the cooling of circulating water, and its water pipe and radiating fin are many to be processed with aluminium, and the aluminum water pipe is made flat pattern; Radiating fin band corrugated is paid attention to heat dispersion, and installation direction is perpendicular to the direction of air flow; Accomplish that as far as possible windage is little, it is high that cooling effectiveness is wanted.

Intercooler a: part that is pressurization system.When air can be produced very high livings heat after the compression at high proportion, thereby air expansion density is reduced, engine temperature is too high to cause damage and the while also can make.In order to obtain higher volumetric efficiency, need before injecting cylinder, cool off high temperature air.This just need install a radiator additional; Principle is similar to radiator of water tank; The HTHP air dispersion is arrived in many tiny pipelines, and pipeline there is normal temperature air high speed flow mistake outward, thereby reaches cooling purpose (can gas temperature be dropped to 50 deg.c from 150 degrees centigrade).Because this radiator between motor and turbosupercharger, so be called central cooler again, is called for short intercooler.

Air-cooled intercoopler can be installed in front, the next door of engine water tank or be installed in one in addition and independently (all can have more a people air port on a lot of diesel commercial car protecgulums on the position; That generally all is to supply intercooler to use). its waveform aluminum thermal fin and pipeline and engine water tank structural similarity, heat conduction efficiency is high.On the other hand; Middle cooling technology needs complicated control mechanism again; Air is overheated to no effect wastes one's time, and crosses the cold condensed water that in suction tude, forms and can try to be clever only to end up with a blunder, and therefore will intercooler and turbosupercharger be mated accurately. and make pressurized air meet the requirements of chilling temperature.

Yet at present engine radiator and intercooler generally all is to be two parts products, and stack was installed before and after they distinguished, and volume is big, installs loaded down with trivial details.Radiating effect poor (hot blast that produces through intercooler influence the normal radiating effect of radiator), next door perhaps are installed in one independently on the position in addition, and wind-force less (not in fan center) cooling-down effect is bad.

Said intercooler is pressed into steam chest to the HTHP air through pressure; The air that gets into gets in the lower chamber process through the core body assembly; Through itself and the contacting with heat-shift and be installed in that air-flow that the fan of rear end forms quickens and the heat exchange of ambient air of ambient air, cold effect in obtaining.

Said radiator is through said upper tank and intake pipe and lower header and outlet pipe forms the heat that circulates reduction heat radiation core body of cooling water in core body and the air-flow that forms through the fan that is installed in the rear end quickens and ambient air, reaches the effect of heat radiation.

Between said suction port and the air outlet between connected part and intake pipe and the outlet pipe connected part be to constitute by cooling tube and heat-radiation belt, heat-radiation belt is between adjacent cooling tube, said heat-radiation belt closely is close together with cooling tube, frame fixation is passed through in the outside.

Said cooling tube and heat-radiation belt are processed by aluminum material, disposable welding fabrication.

Lower chamber and lower header that described intercooler and radiator upper end has upper gas chamber that its dividing plate separates and upper tank and lower end to have its dividing plate to separate; The heat of heat dissipation and water that the cooling tube and the heat-radiation belt of the core body assembly that intermediate portion is shared and the air-flow that forms when adding fan two work that is installed in the rear end quicken gas is diffusing; Complement each other, thus the effect of cold-peace heat radiation in obtaining.

The invention has the beneficial effects as follows that the radiator and the intercooler that have solved motor of the prior art are two parts products; Two functions that had that possessed engine radiator and intercooler; Thereby the reduction manufacture cost reduces installation volume, improves radiator performance; Having improved the efficient of motor simultaneously, is the upgrading products of energy-saving and environmental protection, safety.
