The invention relates to the technical field of vehicles, and particularly discloses a commercial vehicle chassis and a commercial vehicle. The commercial vehicle chassis comprises a frame, a front wall grille and a cooling module arranged between the front wall grille and an engine; the cooling module comprises an intercooler, a radiator, a shroud and an engine fan; a flow guide part is arranged on the radiator in a surrounding mode and comprises a flow guide part body connected with the radiator and a flow guide cover arranged on the side, close to the intercooler, of the flow guide part body, and the cross sectional area of the flow guide cover is gradually reduced in the direction from the front wall grille to the engine so that hot air around the engine can be prevented from flowing back to the front of the intercooler. A backflow prevention structure is arranged on the surface, facing the engine fan, of the air protection ring and used for limiting hot air around the engine fan from entering the engine fan. According to the commercial vehicle chassis, a front cross beam between the radiator and the front wall grille is removed, the ventilation performance is improved, the flow guide part and the backflow prevention structure are arranged, hot backflow of an engine is blocked, and the cooling performance is greatly improved.

    本发明涉及车辆技术领域,具体公开了一种商用车底盘及商用车,该商用车底盘包括车架、前围格栅和设置在前围格栅和发动机之间的冷却模块;冷却模块包括中冷器、散热器、护风圈和发动机风扇;散热器上围设有导流件,其包括与散热器相连的导流件本体和设置在导流件本体靠近中冷器一侧的导流罩,由前围格栅到发动机方向,导流罩的横截面积逐渐减小,以阻挡发动机周围的热风回流至中冷器的前方;护风圈朝向发动机风扇的表面上设有防回流结构,用于限制发动机风扇四周的热风进入发动机风扇。该商用车底盘去掉了散热器与前围格栅之间的前横梁,改善了通风性能,并且通过设置导流件和防回流结构,阻隔了发动机的热回流,冷却性能大大提高。
