Automobile tail gas waste heat absorption device based on phase change energy storage

Abstract

The invention relates to an automobile tail gas waste heat absorption device based on phase change energy storage. The automobile tail gas waste heat absorption device based on phase change energy storage is mainly composed of a heat insulation shell, a tail gas pipe component, an oil guiding pipe and composite phase change materials. The tail gas pipe component comprises a tail gas inlet pipe, tail gas guiding pipes and a tail gas outlet pipe. The two ends of each tail gas guiding pipe penetrate through the side walls of the heat insulation shell correspondingly and are collected to the tail gas inlet pipe and the tail gas outlet pipe. The tail gas guiding pipes and the oil guiding pipe are fixed to the two side walls of the heat insulation shell in a thread mode. The composite phase change materials are used for filling the heat insulation shell and make direct contact with the tail gas guiding pipes and the oil guiding pipe. According to the automobile tail gas waste heat absorption device based on phase change energy storage, the exhaust guiding direction and the tail gas exhausting performance of an original exhaust system are not changed; and the waste heat of high-temperature tail gas is absorbed through the physical state change of the composite phase change materials, the utilization rate of the automobile tail gas is increased, and energy is saved.

Description

technical field [0001] The invention relates to the field of automobile parts, in particular to a device for collecting waste heat from automobile exhaust by utilizing the property of absorbing a large amount of heat energy when the state of the phase-change energy storage material changes. Background technique [0002] With the continuous development of industry, the problem of energy shortage cannot be ignored. In recent years, new energy vehicles have been put on the market and started to be used on a small scale. New energy vehicles have the advantages of low cost of use and effective reduction of oil resource consumption. However, due to the immaturity of new energy technologies such as electric energy and solar energy, the use experience of corresponding new energy vehicles is poor, the overall cost is high, and the anti-collision performance is lower than the general level, which cannot replace traditional fuel vehicles in a short time. [0003] At present, the effi...
