Rear-mounted bus engine compartment heat radiation device and mounting mode thereof

Abstract

The invention discloses a rear-mounted bus engine compartment heat radiation device. The rear-mounted bus engine compartment heat radiation device is mounted at the tail end of the top of a bus body,the width of the rear-mounted bus engine compartment heat radiation device is equal to that of a bus, and the rear-mounted bus engine compartment heat radiation device mainly comprises an air inlet grille, a ventilating pipeline, a bus body tail spoiler, a mounting plate, an air outlet and an air inlet. The air inlet grille is arranged at the front end of the ventilating pipeline and connected with the ventilating pipeline, part of airflow enters the ventilating pipeline through the air inlet grille from a bus roof, then external airflow is blown to a high-temperature component in a rear-mounted engine compartment of the bus from the air outlet, and enhanced heat radiation is carried out. The bus body tail spoiler is connected with the ventilating pipeline and used for achieving flow guideand increasing the flowing speed of bus tail airflow. According to the rear-mounted bus engine compartment heat radiation device, head-on wind outside the bus can be supplied into the engine compartment, enhanced heat radiation in the engine compartment is achieved, the heat radiation performance of the rear-mounted bus engine compartment is improved, and the work efficiency of an engine is improved.

Description

technical field [0001] The invention relates to thermal management of an engine compartment of an automobile, in particular to a rear-mounted radiator for an engine compartment of a passenger car and an installation method thereof. Background technique [0002] At present, due to the control of the number of passengers and ground clearance, the engines of large buses are mostly installed at the rear of the vehicle body, that is, the rear-mounted engine compartment. The cooling of the engine mainly includes the water cooling system in the engine combustion chamber, the high temperature components in the engine room such as the radiator and the air cooling system of the exhaust manifold. The cooling fan is the main part of the air cooling system. When the fan rotates, it sucks in air and makes it pass through the radiator to enhance the heat dissipation capacity, accelerate the cooling of the coolant, and achieve the purpose of heat dissipation. [0003] The heat dissipation ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the deficiencies of the background technology, the technical problem to be solved by the present invention is: how to increase the air inlet and outlet speeds by increasing the area of ​​the air vents, so as to solve the demand for ventilation and heat dissipation, avoid the heat damage phenomenon of the rear-engine passenger car, and at the same time not affect the vehicle Security protection, boundary, appearance and other issues, and solve the problem of its installation method
