Description

A kind of combination thermo-electric generation and the vehicle energy saving system of vortex tube principle
Technical field
The present invention relates to the vehicle energy saving system of a kind of combination thermo-electric generation and vortex tube principle, by improving automobile refrigerating System, to improve energy utilization rate and to reduce tail gas heat quantity discharge capacity, belongs to energy-saving and emission-reduction technology of vehicles field.
Background technology
Thermoelectric generation background increases sharply along with the automobile pollution of the world today, uses for improving fuel oil The technology of efficiency has become research emphasis, and the most safely and effectively energy utilizing method have also been obtained and develops on a large scale very much.Nowadays, profit The technology carrying out thermo-electric generation with residual heat of tail gas of automobile reaches its maturity.As far back as 1988, Birkholz et al. was the most to automobile The waste heat of tail gas carries out thermo-electric generation and is studied, but is limited by thermo-electric generation material so that generating effect is unsatisfactory.Day This Nissan Corporation utilizes the multistage temperature difference device oneself developed, cold end use water-cooled cooling to improve hot cold-end temperature difference, Significantly improve generating efficiency.Hi-z company of the U.S. develops a kind of temperature-difference power generation module with Tellurobismuthite. as material, this module It is divided into 4 series, the generated output of 2.5W~19W can be obtained when two ends temperature is 230 DEG C/30 DEG C.Calendar year 2001, Xi'an traffic University proposes method for solving and the analytical formula of thermo-electric generation.General Motors Corporation have developed a kind of utilize vehicle exhaust send out Electric installation, after tested, output, can respectively up to 350W and 600W in FTP operating mode and under highway operating mode for this device Improve fuel economy 5%.2010, South China Science & Engineering University devised a kind of Novel built-in type temperature difference for raising heat transfer efficiency and sends out Electrical equipment, this structure uses separate type recirculated water cooling, and cold end is directly accessed engine water-cooling system for water, and hot junction is directly entered with vehicle exhaust Row convection current/radiant heat transfer, enhances flow field, and temperature field couples with electric field.
The technical background eddy current effect of vortex tube is to be found Lang Geyu nineteen thirty by French physician George, he The eddy current cooling effect being found that in experiment in cyclone separator, the i.e. central temperature of air-flow and each layer of periphery in cyclone separator Temperature be different, center has relatively low temperature, and outer rim has this phenomenon of higher temperature.Nineteen forty-six, Germany's thing Neo-confucian Rudolf Hilsch, about in the experimental papers of vortex tube device, uses detailed information to confirm that vortex temperature is divided From effect, and the problem such as the definition of design, application and temperature effects with regard to vortex tube device proposes a series of achievement in research With valuable suggestion, make vortex tube refrigerator become the refrigeration machine of a kind of practicality, and have adverse current and two kinds of fundamental types of following current, But do not obtain due attention owing to its thermal efficiency is low.Energy exchange processes owing to occurring in pipe is extremely complex, to eddy current The explanation of tube effect is also that opinions vary, does not has a kind of explanation made us and being satisfied with very much.Therefore, being the most still difficult to be given can essence Really predict the mathematical model of vortex tube performance.
In recent years, through constantly research with improve, the adiabatic efficiency of vortex tube improves constantly, in addition its simple in construction, make Valency is cheap, movement-less part, the feature of employing low-pressure gas refrigeration working medium, therefore, is increasingly becoming the refrigeration that development prospect is wide Device.In the past few years, many countries such as France, India, Japan, the Soviet Union, the U.S., Denmark, Holland and Britain are all being engaged in vortex tube The research-and-development activity of refrigerator, and answered in fields such as gas liquefaction, natural gas and oil gas purification, instrument, aviations With.But China is because putting undue emphasis on the poor efficiency of vortex tube, and have ignored the superiority of its uniqueness so that the experiment of this respect and machine Reason research is carried out seldom, and applied research is the most almost nil.Along with natural gas and the development of liquefied natural gas industry and to peace Complete reliable Small Refrigerating Equipment and the demand of environmental protection, the application for vortex tube provides a huge chance.Believe along with section The progress of skill and the research to vortex tube, vortex tube will have the most wide application space.
Literature research shows, Chinese scholars has carried out substantial amounts of research to automotive energy-saving emission-reducing, and vehicle exhaust and vapour The focus that car air conditioning system is studied especially, but the rare report that vortex tube is used for automotive air-conditioning system.But vortex tube is at vapour In car, the superior function tool of auxiliary air conditioner refrigeration has great advantage, in some instances it may even be possible to replace air conditioner refrigerating completely.At existing automobile In tail gas research, being simply stored directly in automobile storage battery by the electric energy converted by thermo-electric generation sheet, electric energy is not yet It is used more effectively.
Therefore, the present invention attempts being used for vortex tube automotive air-conditioning system first, and utilizes the electric energy that thermo-electric generation obtains It is driven, to be greatly improved automotive energy-saving emission-reducing effect.
