Abstract
The utility model discloses a cooling system for a passenger car. The cooling system for the passenger car comprises air-inlet grilles mounted on a car rack, a cooling air duct, a heat radiator and a cooling fan, wherein an air inlet is arranged at the bottom of the cooling air duct; a guide plate capable of opening or closing the air inlet is hinged on the car rack, and comprises a guide part for preventing hot air at one end of the cooling fan from reflowing into the air-inlet grilles at a state of closing the air inlet; the cooling system in two different travelling working conditions including a high speed and a low speed of the passenger car can be improved through the guide plate; aiming at a condition of insufficient cooling air in a high-speed travelling process of the passenger car, the guide plate is opened, and the cooling effect of the heat radiator of an engine can be enhanced by introducing air flow; and aiming at a condition of reflowing the hot air in a low-speed travelling process of the passenger car, the hot air is prevented from reflowing through the guide part of the guide plate, and a temperature of the cooling air at the air-inlet grilles is prevented from being improved, so that the cooling effect is ensured, simple and practical structure is realized, and the applicability is strong.
Description
Technical field
The utility model relates to a kind of automobile cooling system.
Background technology
Automobile cooling system is the important component part of automobile, and the cooling system of engine at extreme rear passenger vehicle is made of air inlet barrier, cooling air channel, intercooler, radiator, cooling fan etc.During bus driving, cooling-air enters cooling air channel by air-inlet grille, to radiator and intercooler carry out cooling after, via cooling fan to air outlet, due to the impact that is subject to complete vehicle structure, the passenger vehicle cooling recirculation system can produce the problem of local flow stagnation and hot reflux, cooling performance is caused seriously influence, specifically, when the passenger vehicle low speed driving, cooling-air after being heated is after air outlet is discharged, and can reflux enters air-inlet grille, causes cooling air temperature higher; When passenger vehicle is run at high speed, can form large-area stagnant area in cooling air channel, cause the cooling-air charge not enough, above two kinds of situations all can cause cooling effectiveness low.
Summary of the invention
Technical problem to be solved in the utility model is: the automobile cooling system that a kind of good cooling results is provided.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of bus cooling-system system, comprise the air-inlet grille, the cooling air channel that are installed on vehicle frame, radiator and cooling fan, the bottom of described cooling air channel offers admission port, be hinged with the deflecting plate of opening or closing described admission port on described vehicle frame, described deflecting plate is included in the hot air reflow that prevents cooling fan one end under the state of closing admission port and arrives the drainage section of air-inlet grille.
As a kind of preferred, described drainage section is an end of arc and the hinged place far away that is installed on deflecting plate.
owing to having adopted technique scheme, when passenger vehicle is run at high speed, open deflecting plate, windstream during with bus driving is introduced cooling air channel and is carried out cooling to radiator, when the passenger vehicle low speed driving, closed deflecting plate, drainage section stops hot air reflow to the air-inlet grille of discharging to be located, thereby prevent the hot air temperature raising that air-inlet grille is refluxed, reduce cooling performance, therefore can improve for the cooling system under passenger vehicle high speed and two kinds of different driving cycles of low speed by deflecting plate, the situation of cooling-air charge deficiency when running at high speed for passenger vehicle, by introducing air-flow, reinforcement is cooling to engine radiator, the situation of hot air reflow during for the passenger vehicle low speed driving, the drainage section by deflecting plate stops hot air reflow, prevents the temperature increase of the cooling-air at air-inlet grille place, has guaranteed cooling performance, and simple and practical, applicability is strong.
Section is an end of arc and the hinged place far away that is installed on deflecting plate due to described drainage, hot air out flows to air-inlet grille by cooling fan, when flowing to drainage section, flows to the passenger vehicle afterbody under the guiding of arcwall face, prevent from being mixed into air-inlet grille with automobile windstream, improve cooling air temperature.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation of the deflecting plate of the utility model embodiment;
1, air-inlet grille; 2, radiator; 3, cooling fan; 4, vehicle frame; 5, cooling air channel; 6, deflecting plate; 61, drainage section.
The specific embodiment
As shown in Fig. 1 and Fig. 2 are common, a kind of bus cooling-system system, comprise the air-inlet grille 1, the cooling air channel 5 that are installed on vehicle frame 4, radiator 2 and cooling fan 3, the bottom of described cooling air channel 5 offers admission port, be hinged with the deflecting plate 6 of opening or closing described admission port on described vehicle frame 4, described deflecting plate 6 is included in the hot air reflow that prevents cooling fan 3 one ends under the state of closing admission port to the drainage section 61 of air-inlet grille 1, and described drainage section 61 is for arc and be installed on an end of the hinged place far away of deflecting plate 6.
When passenger vehicle is run at high speed, open deflecting plate 6, windstream when deflecting plate 6 will be bus driving is introduced 5 pairs of radiatores of cooling air channel 2 and is carried out cooling, when the passenger vehicle low speed driving, closed deflecting plate 6 sealing admission ports, into the passenger vehicle afterbody is guided the hot air that refluxes by drainage section 61, and the hot air reflow heel windstream of avoiding refluxing is mixed into the temperature increase that air-inlet grille 1 is caused cooling-air, thereby improves the cooling performance of cooling system.
Claims (2)
1. bus cooling-system is united, comprise the air-inlet grille, the cooling air channel that are installed on vehicle frame, radiator and cooling fan, it is characterized in that: the bottom of described cooling air channel offers admission port, be hinged with the deflecting plate of opening or closing described admission port on described vehicle frame, described deflecting plate is included in the hot air reflow that prevents cooling fan one end under the state of closing admission port and arrives the drainage section of air-inlet grille.
2. bus cooling-system as claimed in claim 1 system is characterized in that: described drainage section is an end of arc and the hinged place far away that is installed on deflecting plate.
