Flange plate heat exchange type automobile tail gas power generation device

Abstract

The invention discloses a flange plate heat exchange type automobile tail gas power generation device, and belongs to the field of automobile tail gas power generation. The flange plate heat exchange type automobile tail gas power generation device comprises a tail gas pipe, the tail gas pipe is divided into a high temperature section, a power generation and heat dissipation section and an exhaust section, and a first power generation module is arranged on the periphery of the high temperature section; the power generation and heat dissipation section is provided with at least two flange plates in the circumferential direction, the flange plates are respectively of a shell structure, internal cavities of the flange plates communicate with the tail gas pipe, included corners formed by the two sides of each flange plate and the tail gas pipe communicate with the exterior, and second power generation modules are arranged on the flange plates; and through the flange plates, the surfaces making contact with air are expanded, and the power generation modules can be fixed more easily. According to the device, through improved design of the structure of the tail gas pipe, the heat dissipation performance of the tail gas pipe is not influenced on the premise of thermoelectric power generation, power generation and heat dissipation are effectively combined, and the development of the tail gas power generation technology is greatly promoted.

Description

technical field [0001] The invention relates to the technical field of tail gas power generation, and more specifically relates to a wing plate heat exchange type automobile tail gas power generation device. Background technique [0002] With the development of my country's automobile industry, the energy-saving issues of vehicles are getting more and more attention. More than 60% of the energy in the fuel consumed by the internal combustion engine has not been effectively utilized, and most of it is discharged into the atmosphere in the form of waste heat from automobile exhaust, and the temperature of the exhaust gas can reach above 600°C. [0003] The use of semiconductor thermoelectric power generation technology can effectively recover the exhaust heat of the car in progress, and install it on the exhaust pipe of the internal combustion engine, which can directly convert the waste heat of the internal combustion engine into electrical energy for the use of electrical eq...

AI Technical Summary

Problems solved by technology

The patented solution is distributed around the exhaust pipe and has a closed shell on the outside. Although it is equipped with a cooling fan, it cannot form convection with the low-temperature air outside, and it is difficult to reduce the temperature, resulting in low power generation efficiency and high exhaust gas temperature.
