Description
Technical field
The utility model relates to a kind of device for internal-combustion engine heat radiation, belongs to internal-combustion engine technical field of heat dissipation.
Background technique
Internal-combustion engine is since appearance, and the radiator of internal-combustion engine experienced by the pipe rock radiator three phases be developed so far from tubular type, pipe type, and corrugated tube type is the mode generally adopted now.The radiating mode of pipe rock radiator is that the heat of cooling liquid is delivered to heat-radiation belt by heat dissipating pipe, and air-flow is taken away heat by heat-radiation belt, and cooling liquid and air-flow do not contact and mix.The thermal resistance of being detained bottom in thermal conduction study is the maximum difficult point that heat transfer need be captured always.
Along with the increasing of power of IC engine and increasing of peripheral parts, the radiating efficiency of radiator requires more and more higher, installation dimension is more and more narrower, pipe rock radiator must move towards light-weight design and manufacture, heat dissipating pipe is developed to 0.09MM from 0.25MM, heat-radiation belt is developed to 0.05MM from 0.20, and heat-radiation belt is from flat rubber belting structural development to design of windowing.
Single from material thickness, pipe rock radiator is ultimate attainment close to being developed to.And internal-combustion engine is quite different, along with the demand that technology constantly promotes and environmental requirement continues to increase, motor fuel will burn more and more abundant, and power continues to increase, and urgently the structure generation essence change of radiator carrys out the performance of heat radiation device.
Radiator in use for some time performance degradation is the insurmountable problem of industry, the degree that the working environment difference of internal-combustion engine directly causes radiator performance to be decayed is different, at dust and the many environment heat sink of foreign material because the cancellated reason in front adhesive dust and foreign material can have a strong impact on the performance of radiator between surface and fin, internal-combustion engine damage case caused because of it is innumerable, and this is the crux that cannot overcome for corrugated tube type structure.
Pipe rock radiator is constantly thinning more and more higher for technological requirement along with material, and processing technology is complicated, and weld bond is many, and yield rate is on the low side, and manufacture cost is high, and manufacturing mechanism drops into and strengthens.
Summary of the invention
For the deficiency that existing internal-combustion engine heat dissipation technology exists, the utility model provides a kind of thermal chocking without being detained bottom, the direct-cooled open type internal combustion engine sink of good heat dissipation effect.
Direct-cooled open type internal combustion engine sink of the present utility model, by the following technical solutions:
This heat radiator of internal-combustion engine, comprise combination cooling room, condensation chamber and liquid storage room, condensation chamber is connected with liquid storage room by reflow pipe, combination cooling room is connected with condensation chamber by connecting tube, combination cooling room is connected with liquid storage room by lower liquid pipe, liquid storage room is provided with liquid outlet, combination cooling indoor are provided with feed liquor injection pipe and air inlet injection pipe, combination cooling room is stretched out in one end of feed liquor injection pipe and one end of air inlet injection pipe, one end that air inlet injection pipe stretches out combination cooling room is provided with blower fan, and condensation chamber is provided with air outlet and filling opening.
Combination cooling indoor are provided with pulverizer plate, and the joint of combination cooling room and condensation chamber is positioned at the top of the indoor pulverizer plate of combination cooling.
Room is provided with overflow hole to combination cooling, can overflow in hole thus during coolant injection excess.
The running of above-mentioned direct-cooled open type internal combustion engine radiator is as described below:
The feed liquor injection pipe of direct-cooled open radiator is connected with the water outlet of internal-combustion engine, and air inlet injection pipe is connected in the air outlet of blower fan, and water chamber liquid outlet is connected in internal-combustion engine water intake.The cooling liquid heated by internal-combustion engine enters feed liquor injection pipe injection pipe by internal-combustion engine water outlet and sprays into after pulverizer plate is clashed in mixed air vessel and become vaporific, and cold airflow delivers into air inlet injection pipe by blower fan and sprays into mixed air vessel.Two fluids directly carry out heat exchange in combination cooling room, and cooled liquid flows into lower liquid pipe and enters water chamber and enter internal-combustion engine water intake by water chamber liquid outlet and enter internal-combustion engine circulation cooling again.Entered by outside the air outlet discharge system of condensation chamber after condensation chamber condensation by the air-flow heated, condensed liquid is back to water chamber by reflow pipe and participates in circulation cooling.
The difference that the utility model and existing corrugated tube type dispel the heat is:
The heat exchange mode of corrugated tube type internal-combustion engine heat radiation is that fluid (cooling liquid) heat is delivered to outer wall by radiating pipe wall inwall, and most of heat is delivered to heat-radiation belt by outer wall, takes away heat, reach heat radiation object by cold airflow through during heat-radiation belt.The heat transmission of being detained bottom in heat transfer process is a difficult problem always, being detained bottom is the fluid being attached to the wall bottom, this layer is state of rest, heat transmission just can must be transmitted on radiating pipe wall by this layer fluid, the heat-transfer coefficient of fluid is far smaller than the heat-transfer coefficient of metallic material, which forms thermal resistance, corrugated tube type heat radiation fundamentally cannot remove the thermal chocking of being detained bottom.
And the utility model adopts Open architecture, cooling liquid after participation internal-combustion engine is dispelled the heat directly contacts mixing with outside cold airflow, fundamentally remove the thermal chocking of being detained bottom, make the fluid in hot junction (cooling liquid) rapidly and carry out thermoconvection with cold junction (cold airflow) to greatest extent and reach thermal equilibrium, make cooling liquid reduce temperature fast, greatly can improve radiating effect like this.
