Abstract
The utility model relates to a rear engine cooling system which can be used for cooling engine, and can be used for water cooling system and air cooling system. The utility model is composed of a radiator, a fan, an air channel, etc. The front wall of a passenger vehicle is provided with the air inlet of the air channel which can lead the wind stream in the radiator of the engine for cooling in the course of running. The lower part of the floor of the passenger vehicle is provided with the air channel which is composed of an air inlet segment, an air outlet segment and a middle segment. The air outlet is arranged towards the front of the radiator, and an air regulating device is arranged in the air channel. The utility model has the advantages of good effect, and simple and novel structure; the air inlet is arranged on the front wall of the passenger vehicle, which can cool the radiator of the engine with the wind stream which is led in from the air channel.
Description
The utility model provides a kind of bus aic cooling system for rearmounted engine, and it is used for motor is cooled off, and both can be used for engine water-cooling system, can be used for the air-cooled system of motor again.
Existing bus aic cooling system for rearmounted engine is made of radiator, fan, air channel etc., and the intake grill in air channel is located at passenger vehicle gusset rear portion near the engine radiator place, and exhaust outlet is located on the back wall of passenger vehicle, the close together of intake grill and exhaust outlet.When its deficiency is that bus driving advances, the air-flow at gusset rear portion is turbulent condition, and be negative pressure, the air-flow of back wall portion is the eddy current state, so just influence entering (cooling air) and discharging (hot air behind radiator) of air-flow, thereby cooling effect is not good, when serious, has to stop to travel.
The purpose of this utility model is to overcome above-mentioned deficiency, and provides a kind of cooling effect good bus aic cooling system for rearmounted engine.
The purpose of this utility model is achieved in that bus aic cooling system for rearmounted engine is made of radiator, fan, air channel etc., the air channel is arranged on the bus deck bottom, the intake grill in air channel is placed before being located at passenger vehicle, and the windstream during bus driving is introduced by the air channel radiator is cooled off.The air channel is made up of wind inlet section, intermediate section, wind outlet section, the intake grill of wind inlet section is placed before being connected in passenger vehicle, the exhaust outlet of wind outlet section is facing to the front of radiator, connect to advance wind outlet section before and after the intermediate section, the air channel is installed in the bus deck bottom by made such as metallic material, plastics, glass fibre reinforced plastics, rubber product, timber, fabrics.The air channel intermediate section can be made of the flute profile floor and the gang way floor of passenger vehicle, also can be made of the level land plate and the shaping board of passenger vehicle.The shape in air channel: intake grill, exhaust outlet are tubaeform, and remaining part is geometrical shapies such as semicircle or rectangle, polygonal, V-arrangement.Be provided with volume damper in the middle of the air channel.The front of radiator is facing to the exhaust outlet in air channel, and the back is mounted with fan.Hot air behind the fan suction cooling radiator is discharged from the back wall exhaust port.
Advantage of the present utility model is to place before intake grill is arranged on, by introducing air-flow, cooling effect to engine radiator is good, cooling unit is simple and practical, but also be mounted with volume adjusting apparatus, no matter be that the temperature in the time of all making engine operation remains in the standard-required scope in the spring, summer, autumn and winter or the north, south.
Fig. 1 is the bus aic cooling system for rearmounted engine layout plan.
Fig. 2 is the bus aic cooling system for rearmounted engine plan view.
Fig. 3 is an air channel intermediate section sectional drawing (I).
Fig. 4 is an air channel intermediate section sectional drawing (II).
In conjunction with the accompanying drawings embodiment of the present utility model is further described.Bus aic cooling system for rearmounted engine is made up of radiator, fan, air channel etc., the air channel is arranged on the bus deck bottom, present embodiment is a water-cooled system, and the intake grill in air channel is placed before being arranged on passenger vehicle, and the windstream during bus driving is introduced by the air channel radiator (5) is cooled off.The air channel is by wind inlet section (1), intermediate section (3), wind outlet section (4) is formed, the air channel manufactures the enclosed shape pipeline by metallic material, be installed in the bus deck bottom, before being connected in, encloses on (10) intake grill of the wind inlet section in air channel (1), the exhaust outlet of wind outlet section (4) is facing to the front of radiator (5), the back of radiator (5) also is equipped with fan (6), hot air behind the suction cooling radiator is discharged from passenger vehicle back wall exhaust port, connect to advance wind outlet section before and after the air channel intermediate section (3), constitute as the flute profile floor (9) and the gang way floor (8) of Fig. 3 intermediate section (3) by passenger vehicle.Gang way floor (8) is connected on the trough slab (9).As Fig. 4, second embodiment, air channel intermediate section (3) is made of the level land plate (11) and the shaping board (12) of passenger vehicle, and shaping board (12) is connected on the level land plate (11).The shape in air channel: intake grill, exhaust outlet are tubaeform, and remaining part is a rectangle.Volume damper (2) is installed in the air channel.
