    • All-plastic, sandwich solar collector designed as self-supporting and spatially flexible, comprising a body formed from a frame, two outer plates (2), a top plate and a bottom plate, between which a heat absorber plate (3) is placed parallel, whereby both outer plates (2) are designed as transparent plastic panels containing throughout the whole length at least one row of channels separated from one another, and the heat absorber plate (3) likewise contains throughout the whole length at least one row of flow channels separated from one another and at both ends throughout the whole width of the heat absorber plate (3) is fitted with a profile containing a connecting gutter (19), a distribution channel (20) and an end piece (21) of the distribution channel for inlet or outlet of the heat-bearing fluid, characterised in that the outer plates (2) are fixed in the frame (1), which is formed from straight parts and corner elements, and at least the straight parts of the two longer diametrically opposed sides from the internal side of the frame (1) are fitted with a guidance ledge (22), for seating the heat absorber plate (3), whereby the guidance ledge (22) is, in the middle area, as regards the length of the collector, is fitted with at least one fixing pin (10) for freely snapping into at least one slot (4) at the respective points of the edges of the heat absorber plate (3) for allowing dilation movement of the heat absorber plate (3) lengthwise and crosswise, whereby the frame (1) is fitted with lengthwise side openings (12), and each lengthwise side opening (12) is equipped with a flexible collar (13) for sealing the space between the end piece (21) of the distribution channel (20) and the frame (1), whereby the parallel position of the heat absorber plate (3) between the top plate (2) and the bottom plate is maintained by a system of spacers (5) fixed on the inner surfaces of the outer plates (2), and, between the said outer plates (2) and the heat absorber plate (3) an insulation layer is created in the form of an air gap given by the size of the spacers (5).
    • 设计为自支撑和空间柔性的全塑夹心太阳能收集器,包括由框架形成的主体,两个外板(2),顶板和底板,其间放置吸热板(3) 由此两个外板(2)都被设计成透明塑料板,其中整个长度上包含至少一排彼此分离的通道,并且吸热板(3)同样在整个长度上包含至少一行 在吸热板(3)的整个宽度处彼此分开并且在两端分开的流动通道装配有包含连接槽(19),分配通道(20)和端部件(21)的轮廓 用于所述承载流体的入口或出口的分配通道,其特征在于,所述外板(2)固定在框架(1)中,所述框架(1)由直的部分和角部元件形成,并且至少两个 更长的直径 框架(1)的内侧的相对的侧面装有引导凸缘(22),用于安置吸热板(3),由此导向凸缘(22)在中间区域中关于 收集器的长度装配有至少一个固定销(10),用于在吸热板(3)的边缘的相应点处自由地卡入至少一个槽(4)中,以允许吸热器 板(3)纵向和横向,由此框架(1)装配有纵向侧开口(12),并且每个纵向侧开口(12)配备有柔性套环(13),用于密封端部件 分配通道(20)和框架(1)的平面位置(21),由此顶板(2)和底板之间的吸热板(3)的平行位置由固定的间隔件(5) 在外板(2)的内表面上,并且在所述外板(2)和吸热板( 3)由间隔物(5)的尺寸给出的气隙形式产生绝缘层。
