High-efficiency automobile exhaust heat and electricity recovery device

Abstract

The invention relates to an efficient automobile exhaust thermoelectricity recovery device to achieve the purpose of improving of automobile fuel economy. The device is characterized in that a stainless steel tube is arranged between a catalytic cracker and a silencer of an exhaust tube system. A thermoelectricity recovery unit is added on the stainless steel tube, and heat at the cold end of a circular thermoelectricity chip is conducted to a cold end circular aluminum alloy heat plate to be cooled through an ultra-thin high-temperature graphite washer between the circular thermoelectricity chip and the cold end circular aluminum alloy heat plate. The device is assembled through a plurality of heat exchanger minimum units which are not affected mutually. A system thermoelectricity conversion unit which is controllable in energy transmission, that is, extendable in size and power through heat tube own heat transmission characteristics, is formed by the combination of the heat tube technology and shape improved thermoelectric materials. The device can be integrated with the silencer in limited automobile bottom space to form a multifunctional substitution product.

Description

technical field [0001] The invention relates to a high-efficiency automobile exhaust heat and electricity recovery device, which is applied to the exhaust pipe system of a car and is suitable for commercial passenger cars with poor fuel economy, urban off-road vehicles and small pickups and other mid-to-high-end vehicles. Background technique [0002] Since the global energy crisis occurred in the 1970s, energy issues have been widely valued by all countries in the world. While all major economic countries are striving to seize the energy market, they have also greatly increased their emphasis on energy-saving technologies. With the improvement of people's living standards, the number of automobiles is increasing, and the proportion of automobile energy consumption in the total energy consumption is getting higher and higher. The issue of automobile energy saving has attracted more and more attention from all countries. With the rapid development of my country's automobile i...

Problems solved by technology

Although all the above-mentioned designs claim to have relatively high power output in the thermoelectric power generation system, they have not actually considered the characteristics and stability of the heat transfer of the exhaust gas to the heat exchanger structure in the radial direction, and the long-term life cannot be guaranteed.

It can only be used as an experimental product and cannot enter the actual production and practical stage
