A highly integrated cylindrical thermoelectric power generation noise reduction device

Abstract

A highly integrated cylinder-type thermoelectric generation noise-abatement device comprises cylinder-type high temperature gas tanks, cylinder-type cooling water tanks, thermoelectric modules, a thermal insulating layer, and a clamp device. The number of the cylinder-type high temperature gas tanks is n, the cylinder-type high temperature gas tanks are same, independent and hollow, and the cross section of the middle portion is of a sector shape. The number of the cylinder-type cooling water tanks is n, the cylinder-type cooling water tanks are same, independent and hollow, and the cross section of the middle portion is of a sector shape. Temperature gas tanks and cooling water tanks are combined to form a cylinder body, and the cross section of the cylinder body is similar to a ring form. The outer surface of the cylinder body is fastened by the clamp device. The temperature gas tanks and the cooling water tanks are wrapped inside the noise-abatement device. A guide plate and a spoiler are arranged inside the high temperature gas tank. Compared with the traditional box-type thermoelectric generation device, the highly integrated cylinder-type thermoelectric generation noise-abatement device is compact in structure and capable of generating more electric power by installing more thermoelectric modules in the tail space of a car, and therefore more electric power of the car is generated, and fuel economy of the car is improved. The guide plate and the spoiler guide the flowing of tail gas and reduce tail gas pressure. The cooling water tanks and the thermoelectric modules can effectively lower temperature of the tail gas and reduce energy of the tail gas. The function of noise-reduction and noise-abatement of the car is performed through clamping of the clamp device and the structure of abrupt change of the cross sections.

Description

technical field [0001] The invention relates to a highly integrated cylindrical thermoelectric power generation and muffler device, in particular to a device integrating a thermoelectric power generation device and a muffler which utilizes exhaust waste heat of an engine to generate power at high temperature, and belongs to the technical field of automobile manufacturing. Background technique [0002] According to relevant statistics, about 30% of the total energy of the car engine is used to drive the car, about 30% of the total energy is consumed by the cooling system, and the remaining about 40% of the total energy is discharged from the car exhaust system in the form of high-temperature exhaust gas. If this part of exhaust gas waste heat is recycled, it will effectively reduce the energy consumption of automobiles and reduce the pollution to the environment. However, the size of the traditional box-type thermoelectric power generation device is large in the width directi...

AI Technical Summary

Problems solved by technology

However, the size of the traditional box-type thermoelectric power generation device is large in the width direction, and it is inconvenient to install and arrange in the limited rear space of the car; the thermoelectric module and the cooling water tank are exposed, and additional devices are required for protection, so the overall device volume is too large and the energy utilization rate is low. Low; and because the thermoelectric modules are clamped separately, the clamping force may be uneven, so the working conditions of the thermoelectric modules are uncontrollable
