Description

technical field [0001] 本发明是有关于一种热机装置及其双热源太阳能集热器,特别是指可以选择式地接收太阳热能或 / 及加热热能以驱动热机的装置。 Background technique [0002] 现有的太阳能热机发电装置只能单纯利用太阳能,因此只在有太阳时可以运转,无太阳时则停机,属于被动式(Passive)发电系统。且太阳能热机发电装置在白天运转时若太阳光的强度随时间改变,发电的能力也会随之改变,因此输出电功率欠缺稳定。 [0003] 因此有中国台湾省发明专利公告第I516732号「太阳能聚焦式史特林引擎发电装置」,其中史特林引擎又名史特灵引擎,该案是一种太阳能聚焦式发电装置,为了维持太阳能发电效率,该案设置追光系统,减少史特灵引擎因为太阳移动位置对聚焦温度的不足使史特灵引擎无所动作的问题,并维持输出的电功率。 [0004] 但是如果阴天、雨天及夜晚史特灵引擎就无法运作,在长时间的阴雨天气或在缺少阳光的地区,也有无法发电的问题,因此太阳能热机发电系统通常必须另附加能量储存系统(Energy storage system),以大型电池储存电能或以熔盐系统储存热能继续驱动热机,以维持发电系统供电。然而无论是以电能或热能方式储存,装置成本必须增加,且储存的时间相当有限,在长时间的阴雨天气或在缺少阳光的地区,便无法发电。 Contents of the invention [0005] 爰此,本发明提出一种双热源太阳能集热器,该双热源太阳能集热器用于对一热机加热,以驱动该热机,热机可以持续运作不受天气及时间所影响。 [0006] 为实现上述目的,该双热源太阳能集热器包含:一本体,包括有一太阳能聚热室及一热源室,该太阳能聚热室接受太阳光聚热而产生一太阳热能,该热源室产生或接受一加热热能,该太阳能聚热室与该热源室之间设有一高热传壁,使该太阳能聚热室与该热源室区隔为二空间,该加热热能可以通过该高热传壁传递至该太阳能聚热室。 [0007] 进一步,有一吸热组件,该吸热组件设置于该太阳能聚热室中且连接该热机,使该吸热组件可以接受该太阳热能或 / 及该加热热能。 [0008] 进一步,该太阳能聚热室设有石英玻璃的一透镜,太阳光通过该透镜使该太阳热能传递至该热机。 [0009] 进一步,有一产热单元,...

AI Technical Summary

Problems solved by technology

[0004] However, if it is cloudy, rainy or at night, the Stirling engine will not be able to operate. In long-term rainy weather or in areas lacking sunlight, there will also be a problem of not being able to generate electricity. Therefore, the solar thermal engine power generation system usually requires an additional energy storage system (Energy storage) system), using a large battery to store electrical energy or a molten salt system to store thermal energy to continue driving a heat engine to maintain the power supply of the power generation system

However, whether it is stored in the form of electric energy or thermal energy, the cost of the device must increase, and the storage time is quite limited. In long-term rainy weather or in areas lacking sunlight, power generation cannot be generated.
