Auxiliary power system of automobile

Abstract

The invention provides an auxiliary power system of an automobile. The auxiliary power system of the automobile comprises a thermal energy recovery module, a thermal energy conversion module and a control module, wherein the thermal energy recovery module is used for collecting thermal energy in an exhaust pipe of an internal combustion engine of the automobile; the thermal energy conversion module is used for converting the thermal energy into auxiliary power; and the control module is connected with the thermal energy recovery module and the thermal energy conversion module separately. According to the auxiliary power system of the automobile, the thermal energy in the exhaust pipe of the internal combustion engine of the automobile is absorbed by the thermal energy recovery module, andthen the thermal energy is converted by the thermal energy conversion module into the auxiliary power needed by the automobile, so that the problem of plenty of energy waste caused by low efficiency of conversion from internal combustion oil of the internal combustion engine of the automobile into kinetic energy through combustion is solved, resources are saved, and the reasonability of system arrangement is improved.

Description

technical field [0001] The invention relates to the technical field of automobile design, in particular to an automobile auxiliary power system. Background technique [0002] At present, automobile internal combustion engines generally use fuel combustion as a power source to convert the chemical energy of fuel combustion into kinetic energy; however, when fuel is burned, only about 30% of the chemical energy is converted into kinetic energy, and the conversion efficiency is low. Chemical energy is converted into other forms of energy, such as heat; heat is dissipated directly into the air, resulting in a huge waste of energy. Contents of the invention [0003] One of the objectives of the present invention is to provide an auxiliary power system for a vehicle. [0004] An embodiment of the present invention provides a vehicle auxiliary power system, including: [0005] Heat energy recovery module, used to collect heat energy in the exhaust pipe of automobile internal co...
