Vehicle energy saving system combining temperature difference power generation and vortex tube principle

Abstract

The invention discloses a vehicle energy saving system combining temperature difference power generation and a vortex tube principle. The vehicle energy saving system comprises a gas supply device, a gas storage tank, a vortex tube, a first heat exchanger, a second gas pump, a second heat exchanger and a temperature difference power generation system. The gas supply device supplies gas to the gas storage tank. The input end of the vortex tube is connected with the gas storage tank. A cold gas output pipe of the vortex tube is divided into two branches to be connected with the first heat exchanger and the second gas pump correspondingly. A hot gas output pipe of the vortex tube is divided into two branches to be connected with the first heat exchanger and the second gas pump correspondingly. A stop valve is arranged on each branch. An output pipe of the first heat exchanger and an output pipe of the second gas pump are connected with the input end of the second heat exchanger together. The output end of the second heat exchanger is connected with the gas storage tank. A temperature difference power generation system supplies power to the gas supply device and the second gas pump. According to the vehicle energy saving system, heat in vehicle tail gas is converted into electric energy through the temperature difference power generation system, and noise and temperature of vehicle tail gas emission can be lowered, and because an air conditioner system based on the vortex tube principle is simple in structure, low in power consumption and can be completely self-sufficient, the oil consumption is lowered, and energy conservation and environment protection are achieved.

Description

technical field [0001] The invention relates to an automobile energy-saving system combining thermoelectric power generation and the principle of vortex tubes. The automobile refrigeration system is improved to increase energy utilization and reduce exhaust heat displacement, and belongs to the technical field of automobile energy conservation and emission reduction. Background technique [0002] Technical background of thermoelectric power generation——With the rapid increase of car ownership in today's world, technologies to improve fuel efficiency have become the focus of research, and safe and effective energy utilization methods have also been greatly developed. Nowadays, the technology of using the waste heat of automobile exhaust gas to generate electricity by temperature difference is becoming more and more mature. As early as 1988, Birkholz et al. had studied the thermoelectric power generation of waste heat from automobile exhaust, but the power generation effect wa...
