A heat storage device based on automobile engine exhaust

Abstract

The invention relates to the technical field of thermal energy storage, and discloses a thermal storage device based on automobile engine exhaust. The thermal storage device based on automobile engine exhaust comprises an outer barrel and an inner barrel arranged in the outer barrel. The outer barrel and the inner barrel are arranged coaxially. An end cover is arranged at the right end of the outer barrel. The right end of the inner barrel penetrates through the end cover and extends to form a gas inlet pipe. A gas outlet pipe is arranged in the center of the left end of the outer barrel. The space between the outer barrel and the inner barrel is filled with a plurality of thermal storage balls. Connectors are arranged at the outer end of the gas inlet pipe and the outer end of the gas outlet pipe. The gas inlet pipe and the gas outlet pipe are each provided with a connecting ring, the two connecting rings are connected through a wire rope, and a thermal insulation handle is arranged in the middle of the wire rope. The thermal storage device based on automobile engine exhaust has the beneficial effects of being capable of collecting and storing the thermal energy in automobile exhaust for use as residential energy resources, and high in efficiency of heat absorption and heat release.

Description

technical field [0001] The invention relates to the technical field of heat energy storage, in particular to a heat storage device based on automobile engine exhaust. Background technique [0002] With the improvement of people's living standards, there are more and more automobiles, and the proportion of automobile energy consumption in the total energy consumption is getting higher and higher, and the issue of automobile energy saving has attracted more and more attention. At present, the energy utilization efficiency of automobile engines is generally relatively low. The main reason is that the efficiency of internal combustion engines of automobile engines is not high. Under different working conditions, a large part of the energy of fuel combustion is dissipated with exhaust gas and cooling water. According to a forecast report by a German auto market research organization, although environmental protection has become a global hot topic, the global car ownership will co...
