Abstract

A single-layer exhaust pipe heat shield comprises a shield body, the shield body is suitable for being fixedly arranged below a vehicle chassis, and an exhaust pipe is suitable for penetrating throughthe shield body; and a heat conduction pipeline is arranged in the shield body, a heat supply pipeline is arranged above the vehicle chassis, the heat supply pipeline forms a pipe network and spreadsall over the vehicle chassis, a water inlet valve is arranged at one end of the heat supply pipeline, a water outlet valve is arranged at the other end of the heat supply pipeline, the two ends of the heat conduction pipeline are connected with the water inlet valve and the water outlet valve respectively, the heat conduction pipeline and the heat supply pipeline are filled with a circulating medium, a circulating pump is further arranged on the heat supply pipeline, and the circulating pump drives the circulating medium to flow in the heat conduction pipeline and the heat supply pipeline andconduct heat exchange. The single-layer exhaust pipe heat shield has the advantages of multiple functions and high energy utilization rate.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an exhaust pipe heat shield. Background technique [0002] Whether it is a diesel engine or a gasoline engine, when the engine is running, the high-temperature exhaust gas produced by the combustion of the cylinder will be discharged through the exhaust pipe. The temperature of the gas is quite high, so the temperature of the heat radiation of the exhaust pipe is also very high. Considering various safety factors, in order to prevent the hidden dangers caused by the heat radiation of the exhaust pipe, it is necessary to install a heat shield to reduce its heat radiation. The structure of the heat shield is mostly welded by stainless steel or a splint inlaid with heat-resistant and high-temperature fiber material in the middle. [0003] However, the heat produced by the exhaust pipe on the current automobile is all dissipated naturally, and is not utilized, so there is a certain waste o...
