Description
Technical Field
The invention relates to a functional heat-insulating plate for a vehicle and a processing method thereof, belonging to the technical field of heat-insulating plate processing.
Background
Automotive body panels, also known as heat shields, are thin metal sheets placed between adjacent surfaces in heat transfer engineering to reduce the damage of the radiation heat exchange surfaces to other parts. The vehicle body heat insulation plates are arranged on two sides of the engine and above the exhaust pipe channel at the bottom of the vehicle body. The heat shield mainly utilizes the reflection heat insulation principle of the heat shield to separate the heat transfer, and has certain local noise separation function.
At high speeds, its effect is substantially limited to reducing the transmission of radiant heat flow, since the air flow is faster at the bottom of the car body, which has a cooling effect on the heat generating components, i.e. the convective heat transfer will be beneficial for the heat dissipation of the bottom parts of the car. If the bottom structure design is unreasonable, serious turbulence occurs in the air flow, the convective heat transfer coefficient can be rapidly increased, and poor heat transfer with the automobile body can also be generated, so that the condition needs to be avoided during design. When some vehicles run at high speed, the floor of the vehicle body is locally hot, and at the moment, the heat radiation is stronger due to the higher temperature of an engine and an exhaust pipe, and the heat radiation is also in a certain relation with the poor flow of high-speed hot air at the bottom of the vehicle. The existing heat insulation plate for the automobile mostly adopts a single-layer structure, has poor functionality and cannot meet the requirements.
