Material: low carbon steel, stainless steel, copper, aluminum and other non-ferrous metals
Surface treatment: dusting
Process: blanking - bending - pressing riveting - dusting
Tolerance: ±0.1 mm
Expansion: top cover heat dissipation structure and vehicle. The roof heat dissipation structure includes a ventilation duct extending from the engine compartment toward a top of the vehicle, the ventilation duct having a lower opening communicating with the engine compartment, and an upper opening at an upper portion of the ventilation duct, the roof heat dissipation structure further including a heat shield The heat dissipation cover is located above the opening of the ventilation duct and is disposed above the top skin of the vehicle, and a gap is provided between the bottom of the heat dissipation cover and the roof skin of the vehicle. The top cover heat dissipation structure of the utility model delivers high temperature air in the engine compartment to the roof by installing a ventilation duct communicating with the engine compartment, thereby greatly reducing the temperature in the engine compartment and effectively ensuring the engine performance. Therefore, when manufacturing the chassis heat sink, it is necessary to open the hole.
