Tail gas waste heat recovery power generation device of internal combustion engine

Abstract

The invention discloses a tail gas waste heat recovery power generation device of an internal combustion engine. The device comprises a heat exchanger, a thermoelectricity power generation assembly, a water cooling board, fastening hoops, a high temperature board, an air inlet cone, an air outlet cone, connection flanges and an outer shell. Tail gas of the internal combustion engine is input through the air inlet cone connected with one flange via an exhaust pipe, part of heat in the tail gas is collected by a heat collection device when the tail gas passes through the heat collection device inside the heat exchanger and is conducted to the high temperature board installed at one end of the thermoelectricity power generation assembly through heat transfer media inside the heat collection device, the other face of the thermoelectricity power generation assembly is cooled through the water cooling board filled with cooling water, a temperature difference is generated between the high temperature board and the water cooling board, and the thermoelectricity power generation assembly can generate electricity for charging under the condition that the temperature difference exits. The tail gas waste heat recovery power generation device of the internal combustion engine has the advantages of being simple in structure, convenient to manufacture and assemble and high in power generation efficiency.

Description

technical field [0001] The invention relates to a thermoelectric power generation device, in particular to an internal combustion engine exhaust waste heat recycling device. Background technique [0002] Waste heat thermoelectric power generation is an effective way to convert low-grade energy such as waste heat from internal combustion engine exhaust into electrical energy. At present, there are many ways to recycle waste heat from automobile exhaust, which are divided according to their usage, generally including refrigeration and air conditioning, waste heat power generation, waste heat heating, and improvement Fuel, exhaust gas turbocharging, etc. In recent years, developed countries such as the United States, Japan and the European Union have gradually increased their investment in the use of thermoelectric generators to recover waste heat from automobile exhaust. In 2004, Clarkson University in the United States also invented a thermoelectric generator prototype. Amo...

Problems solved by technology

The power conversion efficiency of a car is only about 40%, and as many as 60% of the energy in the fuel has not been effectively utilized. If 10% of this energy is utilized, it will definitely bring good social benefits and considerable economic benefits. However, judging from the reported research results, the current technology is still immature and there is still a long way to go
