Heat conduction effect and heat radiation effect combining type cascading automobile exhaust heat exchange device

Abstract

The invention discloses a heat conduction effect and heat radiation effect combining type cascading automobile exhaust heat exchange device and belongs to the technical field of automotive energy-saving devices. The heat conduction effect and heat radiation effect combining type cascading automobile exhaust heat exchange device comprises a catalytic purifier, a set of heat exchange units, a corrugated pipe, an auxiliary silencer, a main silencer, a set of cascading pipes, a first exhaust pipe, a second exhaust pipe, a third exhaust pipe, an exhaust tail pipe, a heat exchange device input pipe and a heat exchange device output pipe. The catalytic purifier, the first exhaust pipe, the corrugated pipe, the second exhaust pipe, the auxiliary silencer, the third exhaust pipe, the main silencer and the exhaust tail pipe are connected in sequence. Every two adjacent heat exchange units are communicated through the corresponding cascading pipe. The heat exchange device input pipe is connected to the heat exchange unit outside the main silencer. The heat exchange device output pipe is connected to the heat exchange unit outside the catalytic purifier. According to the heat conduction effect and heat radiation effect combining type cascading automobile exhaust heat exchange device, the manufacturing cost is reduced, and the recovery rate of heat energy is increased; heat energy is conducted to fluid heat-conducting media for the second time through the heat radiation effect, and thus the recovery rate of the exhaust heat energy is further increased.

Description

technical field [0001] The invention belongs to the technical field of automobile energy-saving devices, and in particular relates to a cascaded automobile exhaust heat exchange device with superimposed heat conduction and heat radiation effects. Background technique [0002] More than half of the total energy of automobile fuel is converted into heat energy, which is mainly discharged into the atmosphere in the form of exhaust heat. Recycling and utilization of automobile exhaust heat has attracted people's attention and has become one of the development directions of energy-saving vehicles. The recovery and utilization of waste heat from automobile exhaust mainly includes two links: one is the recovery method, the main form of which is the heat conduction and heat radiation between the solid heat transfer medium and the automobile exhaust pipe, and the heat transfer between the fluid heat transfer medium and the automobile exhaust pipe. The second is the way of utilization...

Problems solved by technology

The disadvantage of this technical solution is: since the evaporation end is located in the exhaust pipe, this not only increases the manufacturing cost of the exhaust pipe, but also affects the smoothness of the exhaust of the car, thereby reducing the output effect of the engine
