What is the role of the car ventilation cover plate? Where is the car air conditioning vent entrance?
The role of the car ventilation cover plate is: 1, to provide the installation environment of the ventilation pipe for the air conditioning air intake system of the car. 2, cover the decoration, provide protection for the wiper shaft mechanism. 3, provide enough air intake for the air conditioning compressor.
The function of the ventilation cover plate is to provide the air intake required by the air conditioner, prevent the external water of the car from entering the air conditioning intake system, and prevent the entry of external debris of the vehicle. In the daily process of using the car, such as parking for a long time or stopping under the tree, the vent on the ventilation cover plate is easy to be blocked by other debris such as leaves, thus affecting the normal operation of the Longtuner system.
As an important part of the vehicle, the ventilation cover plate plays an indispensable role in integrating the functions of the exhaust intake wiper nozzle assembly. In the previous model, the sink sheet metal is installed under the ventilation cover plate, and the rain can flow directly into the sink through the wiper mounting hole or drainage hole, and then discharge out of the car along the sink, effectively preventing the water from flowing into the body and the body sheet metal structure, which can provide a comfortable internal riding space, and prevent the body sheet metal from being corroded by rain.
In order to solve the above technical problems, the utility model provides a drainage structure of a ventilation cover plate, which comprises a water retaining wall of a ventilation cover plate body, a diversion channel and an air intake surface; The water retaining wall, flow guide trough and air inlet surface are arranged on the ventilation cover plate body, the air inlet surface is connected with the flow guide trough, and the water retaining wall is located between the air inlet surface and the flow guide trough. The two ends of the ventilation cover plate body are provided with connecting plates, and the connecting plates are inclined to one side. The connecting plate avoids interference with the head brace. The diversion channel and the air intake surface are connected on both sides near the body of the ventilation cover plate to form a water outlet.
The drainage structure of the ventilation cover plate also includes a head cover split drainage box and a water outlet connected to a splice of the head cover. The hood seam is the upward seam. The diversion groove is a curved groove. The diversion groove has a Z drop from the middle to both ends, which can ensure the smooth discharge of water and will not cause water accumulation on the ventilation cover body. Because there is no runner sheet metal in the layout requirements, it can not meet the requirements of its drainage performance, and can only drain through the two sides of the ventilation cover plate to improve the market of the new car.
The inlet surface has a step difference from the middle to both sides. The step difference prevents a large amount of water from flowing into the inlet. The inlet surface has a convex part. The convex part has multiple air intakes. The water flowing to the air intake side can be discharged along both sides, reducing the amount of water entering the air intake and avoiding air conditioning failures caused by water intake. The utility model also provides a vehicle which comprises a ventilation cover plate drainage structure mentioned in any of the above. The drainage structure of the ventilation cover plate also includes a drainage box; The drainage box is connected to the water outlet. There are two drainage boxes, two drainage boxes can make the water flow to the front wheel cover side to strengthen the outside of the beam to avoid backflow.
Automobile air conditioning vent entrance under the windshield, automobile air conditioning refers to: installed on the car air conditioning device, its role is: 1, the air in the car for cooling, heating, ventilation and air purification; 2, to provide a comfortable driving environment for passengers, reduce the fatigue strength of the driver, improve driving safety. The reasons why car air conditioning is not refrigerated are: 1, the lack of refrigerant fluorine; 2, evaporation box is too dirty; 3, the air-conditioning system failure; 4, refrigerant and freezer oil contain excessive impurities, blockage; 5, the condenser is too dirty, resulting in reduced heat dissipation capacity; 6, the air conditioning filter element will appear stolen goods, odor or blockage.
