Description
Technical field
The utility model belongs to technical field of solar, particularly a kind of a kind of incorporate solar generator coupling assembly relevant with building that utilizes focusing sunlight generating, thermal-arrest.
Background technology
World today's energy is day by day exhausted, and energy crisis will seriously influence the progress and the development of human society.Unremitting effort is all being done for the sustainable development of keeping the earth that taps a new source of energy in the whole world for this reason.Solar energy is the inexhaustible green energy resources of a kind of mankind, and how to effectively utilize and develop solar energy resources is the direction that scientific circles constantly make great efforts always.Early stage silicon photocell and hull cell, the cost of electricity-generating that causes owing to conversion efficiency is low is high; Seriously restricting the popularizing of solar energy generation technology, popularization and commercialization.Pass through scientist's continuous effort in recent years, the photocell technology is greatly improved.Present concentrating solar battery can absorb the sunlight that is equivalent to battery light-receiving area 500-1000 illuminating area doubly, so just greatly reduce battery cost, and conversion efficiency is greatly improved also.For road has been paved in the commercialization of solar power generation.
Yet, use this novel concentrator battery at first need sunlight be focused on the photocell chip through condenser system.Because the sun relatively ball position is changing all the time, this just requires concentrating generating system not fix, and it wants real-time translation-angle that the focus of condenser system is dropped on the photocell chip all the time.Such system is referred to as day by day system's (or being called as solar tracking or sunlight tracking system).Present existing solar energy concentration generating system day by day fixes the back to photocell and optical system to be installed on the big substrate with array way, substrate is installed in the function day by day of the system that realizes on the controlled travel(l)ing rest again.This mode has just produced a sail effect.There is following defective in such system;

2,The waste of drive system energy consumption: the velocity of rotation day by day of concentrating solar power generation system is extremely low; Large-scale drive system need be installed; But just must be equipped with powerful drive motors and powerful decelerator in order to resist huge wind load, to guarantee the rigidity of structure of drive system.
3,Radiating effect difference solar energy utilization ratio is low: because photocell can not convert the energy 100% of sunlight into electric energy; Most of solar energy after the focusing can accumulate in the mode of heat energy on the photocell; If this part heat energy can not consume effectively; Can make photronic temperature constantly raise, produce photic decay, to photoelectric conversion efficiency is reduced until burning.Therefore must dispel the heat with active or passive mode for the partial heat energy that can't change in the solar energy converting process.Existing focusing solar power generation system all is installed in outdoor, because of low can't therefore can only the heat radiation with the passive type air cooling system by the dress water-cooling system of outdoor temperature in winter.Not only the radiating effect difference has influenced photronic conversion efficiency, and the most of heat energy in the solar energy is wasted and can't realize the maximization of conversion of solar energy utilization ratio.
4, system maintenance and electric power transfer cost are high: for being installed in away from the focusing solar power generation system (overwhelming majority) on human settlement's the open-air high mountain; Owing to need erect power transmission lines institute's electricity is transferred to the electricity consumption city; Therefore not only the transmission cost investment is big, the transmission line loss waste is higher, brings very high cost expenditure also for simultaneously the maintenance of transmission system.
