Abstract
The utility model relates to a gasoline engine cooling system. The utility model is capable to settle the relevant problems such as that the temperature of the water flow into/out of the existing engines is too high, the heat-balance performance of the cooling system is poor, etc. A left baffle is arranged at the gap between the left supporting beam and the radiator, and a right baffle is arranged at the gap between the right supporting beam and the radiator; a crossband-shape air inlet is arranged at the lower part of the front bumper, the upper part of the front bumper is in a grille shape, and the total air-intake area is 0.073392 aquare meter. By adding the left and right baffles, the air originally escaped from the gap is led to the surface of the radiator, the air intake coefficient and air intake quantity are increased, the wind which is not used originally is sufficiently used. The utility model cancels one of the two cross slabs under the original bumper, and as a result, the air intake effect is greatly increased and the heat-balance capacity of the cooling system is improved. The total air intake area of the front bumper and the grille on the bumper is 0.073392 aquare meter after being optimized.
Description
Technical field
The utility model relates to the cooling system of spark ignition engine.
Background technology
During engine operation, produce a large amount of heats, temperature can reach 1800～2000 ℃ in the cylinder of spark ignition engine, for make correlated parts can be under high temperature, high pressure stable operation, driving engine must distribute heat in the machine with refrigerant fluid.In general, 30% of the heat after the oil inflame is discharged through freeing pipe by exhaust valve, and 10% left and right sides heat is distributed by Engine Surface, and 30% need be dispelled the heat by cooling system.The cooling system ability is crossed low or too high all unfavorable to engine operation, crosses low meeting and produces detonation, and material does not satisfy thermal stress and damages; The too high formation that then can worsen miscellaneous gas influences rational oil clearance and produces premature wear.The water temperature requirement of general cooling system, when driving engine was worked for a long time, normal working temperature was 90～105 ℃.
Summary of the invention
Too high in order to solve present driving engine Inlet and outlet water temperature, relevant issues such as cooling system heat balance poor performance, the utility model provides a kind of the air of escaping is guided the into cooling system of the spark ignition engine of radiator, enhancing cooling performance.
The concrete structure improvement project is such:
The cooling system of spark ignition engine comprises radiator, radiator fan, expansion tank, condenser and circulating line, and condenser is positioned at the radiator front portion, and radiator is on the cross member of frame between left support beam and the right support beam, and radiator the place ahead is a front bumper.The utility model has adopted the baffle plate of two fast PP materials, be right baffle-plate and right baffle plate, be installed in the both sides of radiator respectively, right baffle-plate one side and left support beam are fixed, the other end leans against on the radiator face, right baffle plate one side and right support beam are fixed, the other end leans against on the radiator face, not only make the layout of radiator periphery more compact, the more important thing is the gap between sealed heat-dissipating device and the vehicle body, avoid a large amount of air from the gap, to escape, influence intake, the air of escaping from the space originally is directed to spreader surface, has enlarged air intake coefficient and intake, will the air quantity that does not utilize to utilize fully originally.
Right baffle-plate becomes 50 °～60 ° and plays the wind-guiding effect with the radiator plane, the wind of escaping originally is directed to spreader surface; Right baffle plate becomes 90 ° with the radiator face, seals.
Right baffle-plate and right baffle plate adopt thermoplastic material to have intensity and non-deformability preferably, the generation of the unfavorable conditions such as breaking of avoiding deforming, and certain optimization function also can be played to the noise that air intake produces in the position that baffle plate is placed.
The radiator front face area is 0.264 sq m, and through calculating, the direct incoming air area ratio of radiator is 16.7%.Requiring on the automobile design the direct incoming air area of radiator is required is 30%, so, need to revise the moulding of front bumper and preceding barrier to meet design requirement.
For making heat balance reach requirement, be that the incoming air area ratio reaches 30%, area must reach 30% * 0.264=0.0792 sq m on the radiator so preceding grid and the total incoming air area of bumper/spoiler project to, grid and the total incoming air area of front bumper were 0.115057 sq m before this can obtain, and grid modification total amount is 0.051097 sq m before bumper/spoiler and its top.Because preceding barrier relates to outward appearance, do not make big modification again, only front bumper is optimized.
The front bumper bottom is provided with horizontal stripe shape ventilation inlet, and front bumper top is the barrier shape, and the total incoming air area percentum after the optimization is 27.8%, is 0.073392 sq m after total incoming air area optimization of barrier before front bumper and its top.

Fig. 2 is the birds-eye view of Fig. 1,
Fig. 3 is the front bumper arrangement scheme drawing.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1 and Fig. 2, the cooling system of spark ignition engine comprises radiator 7, radiator fan, expansion tank, condenser 6 and circulating line, condenser 6 is positioned at radiator 7 front portions, and radiator 7 is installed on the cross member of frame between left support beam 2 and the right support beam 9 by entablatrance 1, cross sill 3 and central support 5.
Gap location between left support beam 2 and radiator 7 is installed with right baffle-plate 4, and the gap location between right support beam 9 and radiator 7 is installed with right baffle plate 8.
Be 50 °～60 ° angles between right baffle-plate 4 and the radiator 7, be 90 ° of angles between right baffle plate 8 and the radiator 7.
Right baffle-plate 4 and right baffle plate 9 materials are thermoplastic plastic.
The radiator front face area is 0.264 sq m, and through calculating, the direct incoming air area ratio of radiator is 16.7%.Requiring on the automobile design the direct incoming air area of radiator is required is 30%, so, need to revise the moulding of front bumper and preceding barrier to meet design requirement.
For making heat balance reach requirement, be that the incoming air area ratio reaches 30%, area must reach 30% * 0.264=0.0792 sq m on the radiator so preceding grid and the total incoming air area of bumper/spoiler project to, grid and the total incoming air area of front bumper were 0.115057 sq m before this can obtain, and grid modification total amount is 0.051097 sq m before bumper/spoiler and its top.Because preceding barrier relates to outward appearance, do not make big modification again, only front bumper is optimized.
