A low-wind-resistance automobile engine compartment cover capable of rapid heat dissipation

Abstract

The present invention proposes a low-wind resistance automobile cabin cover that can dissipate heat quickly. A heat dissipation box is arranged at the bottom of the cabin cover to extract hot air in the cabin. The heat dissipation port is discharged, and the heat dissipation port faces the rear of the vehicle and is close to the upper surface of the cabin cover, so that the heat dissipation device can not only realize the auxiliary heat dissipation of the cabin, but also reduce the air resistance caused by the laminar flow separation phenomenon; the heat dissipation of the cabin cover The box can be communicated with the heat dissipation box through the inner tube of the reinforcing rib, so that the heat dissipation box can adjust the installation position of the heat dissipation box, so as to carry out adaptive installation and use according to different cabin sizes of different models, and has a wide range of applications; the invention has a simple structure, easy installation and It is very easy to disassemble and adjust; the cooling port can also integrate the defogging function; the operation of the cooling box and the cooling box can also be controlled by the car controller to meet the cooling needs of the car at different speeds, which is very practical.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and relates to an automobile cabin cover. Background technique [0002] The engine and other equipment in the car cabin will generate a lot of heat when the car is running, especially in summer when a large amount of hot air gathers in the cabin, relying on natural volatilization for heat dissipation, it is obviously impossible to achieve fast and efficient heat dissipation, so it is necessary Design the car engine compartment cover that can quickly dissipate heat, and it is used for auxiliary heat dissipation of the heat in the engine compartment. At the same time, when the vehicle is running at high speed, due to the viscous friction between the air and the cabin cover, boundary layer separation is formed on the upper surface of the rear of the cabin cover, and even turbulent flow is generated in reverse. This laminar flow separation phenomenon is caused by the vehicle One of the main cause...

[0003] The Chinese invention patent with the publication number CN106627782A provides a cooling type automobile engine cover, wherein a plurality of cooling fans are installed in the center of the lower end surface of the engine cover body, and a plurality of ventilation holes are provided on the engine cover body at the upper end of the cooling fan, and the ventilation holes There is a flip-type ventilation flap on the top, and the lower end of the flip-type ventilation flap is connected to the pneumatic rod device. One end of the pneumatic rod device is fixed on the lower end surface of the hood body, and the other end is connected to the flip-type ventilation cover. The opening direction of the heat dissipation holes in the technical solution is perpendicular to the driving direction of the car. When the car is running at high speed, the external air will enter the heat dissipation box through the heat dissipation holes, which will affect the heat dissipation effect.

The utility model patent with the authorized notification number CN207579958U provides a car with a heat dissipation hood. A heat dissipation chamber is arranged in the hood body. An air inlet and an air outlet connected to the heat dissipation chamber are provided on the hood body. The air inlet It is arranged along the forward direction of the car, and the air outlet is arranged on the rear side of the engine cover body. The air outlet of the air outlet is provided with a wind guide cover, and the air guide cover can guide the hot air at the air outlet to the front windshield. Although this technical scheme It can play a certain auxiliary effect on the heat dissipation of the car, and use the hot air to heat and dry the rainwater on the windshield, but it cannot reduce the wind resistance during the driving of the car
