The invention discloses a flow guide structure for improving the local high temperature on the exhaust side of a longitudinal engine assembly, comprising an engine assembly and a particle trap assembly arranged on the exhaust side of the engine assembly, and further comprising: a flow guide member disposed between the engine assembly and the particle trap assembly, the flow guide member comprising a baffle body and a mounting assembly, the baffle body and the particle trap The assembly is connected through the mounting assembly, the main body of the deflector includes a front section of the deflector, a middle section of the deflector and a rear section of the deflector connected in sequence from front to rear, the front section of the deflector, the engine assembly and a heat source air flow inlet is formed between the particle trap assemblies. The invention solves the local high temperature problem on the exhaust side of the vertical engine assembly, does not need to modify the structure of the engine assembly and the particle trap assembly, has low cost, small modification of the whole vehicle, and short modification period.
Description
technical field [0001] The invention relates to an engine assembly, in particular to a flow guide structure for improving the local high temperature on the exhaust side of a longitudinal engine assembly. Background technique [0002] With the growing demand for pickup trucks in the automotive market, customers' requirements for the use of pickup trucks have gradually increased. From the past to only meet the needs of pulling goods, to the current high-quality multi-purpose family vehicles. With the improvement of the quality of pickup trucks, the requirements for thermal management of the cabin are also more stringent, especially the thermal aging and thermal failure of electrical components in the engine assembly compartment. Limited by the layout of the vehicle engine assembly cabin, the engine assembly of most pickup trucks is longitudinally arranged. When the exhaust side of the engine assembly is outside the fan wake (that is, away from the fan outlet area), it means ...
