Embodiment Construction

[0021] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0022] The automobile includes a body 100 and an engine compartment 200, and the engine compartment 200 is provided with parts 210 such as a heat exchanger, a fan, and an engine. A recirculation zone 300 is formed in the engine compartment 200, and the high-temperature gas in the recirculation zone 300 is difficult to discharge from the engine compartment 200, and the high-temperature airflow in the recirculation zone 300 can be discharged through the cooling device of the present invention, thereby improving the heat dissipation effect in the engine compartment 200 .

[0023] like figure 1 As shown, the heat dissipation device includes a heat dissipation channel 1 having an inlet 11 and an outlet 12 , the inlet 11 is located in the engine compartment 200 near the recirculation area 300 , and the outlet 12 is located at the rear of the vehicl...

Abstract

The invention discloses a radiator of an engine compartment of an automobile. The automobile comprises a body and the engine compartment. When the outside airflow flows through the engine compartment,a recirculation zone is formed in the engine compartment. The radiator comprises a radiating channel. The radiating channel is provided with inlets and outlets. The inlets are located in the engine compartment and are close to the recirculation zone. The outlets are located at the tail of the body. The radiator further comprises a radiating fan arranged at the inlets. The radiator of the engine compartment of the automobile has a simple structure, through the radiating fan in the radiating channel, the hot air which is not easy to be exhausted in the engine compartment can be sucked out in time, thereby improving the radiating performance of the engine compartment; the hot air sucked out passes through the radiating channel and is exhausted from the outlets in the tail of the body, whichcan delay the separation phenomenon of the airflow at the tail of the body, thereby weakening the tailing vortex strength and size of the tail of the body, and further reducing the wind resistance ofthe vehicle.

Description

technical field [0001] The invention relates to the technical field of automobile aerodynamics, in particular to a cooling device for an automobile engine compartment. Background technique [0002] The aerodynamic characteristics will have a great impact on the performance of the car: the external spoiler characteristics affect the wind resistance of the vehicle; the air flow characteristics inside the engine compartment affect the heat dissipation of the components in the cabin. [0003] In 2015, the Ministry of Industry and Information Technology issued the newly revised "Passenger Car Fuel Consumption Limits" and "Passenger Car Fuel Consumption Evaluation Methods and Indicators", stipulating that the average fuel consumption of passenger cars should be reduced to 5.0 liters per 100 kilometers by 2020. In order to achieve this arduous goal, domestic car companies have carried out technical research on energy saving and fuel consumption reduction in multiple ways, among w...
