Abstract

The invention provides an automobile tail gas waste heat recovery fused salt heat transfer and heat storage heat exchanger. The heat exchanger comprises a plurality of pipes for automobile tail gas to flow, a spiral coiler for cooling agents to flow, a front end cover, a rear end cover and a barrel wall. Case layers used for containing fused salt of phase-change materials are further arranged. The plurality of pipes for the automobile tail gas to flow are mutually parallel and fixed in space formed by enclosure of the front end cover, the rear end cover and the barrel wall. The spiral coiler for the cooling agents to flow is wound around outer sides of the plurality of pipes for the automobile tail gas to flow. The case layers used for containing the fused salt of the phase-change materials are respectively arranged between the plurality of pipes for the automobile tail gas to flow, between the pipes for the automobile tail gas to flow and the spiral coiler for the cooling agents to flow, and between the spiral coiler for the cooling agents to flow and the barrel wall. The front end cover is connected with an automobile exhaust pipe. The tail gas after waste heat recovery is exhausted into atmosphere directly through the rear end cover. The heat exchanger solves the problem of heat exchange medium circulation interruption caused by indirectness and randomness of automobile tail gas exhaust, and has the advantages of being strong in heat storage capacity and the like.

Description

technical field [0001] The invention relates to the field of energy saving and environmental protection, in particular to a molten salt heat transfer heat storage heat exchanger for recovering waste heat from automobile exhaust, belonging to the field of waste heat recovery. Background technique [0002] With the rapid development of my country's economy, automobiles are used more and more widely, most of which are ordinary fuel internal combustion locomotives, and a large part of the calorific value of automobile fuel is discharged into the atmosphere along with the exhaust gas. While the automobile satisfies people's travel convenience, the recovery of waste heat from automobile exhaust has been paid more and more attention by people. Moreover, people have higher and higher requirements on the heat exchange performance, high efficiency, energy saving, and environmental protection of waste heat recovery heat exchangers. [0003] At present, most of the waste heat recovery ...
