Abstract

在真空太阳能收集器中，有一个深冲压的无缝收集槽(1)，其内部装有吸收板(9)和通有吸热介质的集热器(12)及(13)，槽(1)上边有突缘(4)，突缘(4)上装有辐照透明玻璃板(7)，玻璃板(7)盖住槽(1)，整个玻璃板盖用彼此分开一定距离的支撑件(17)支撑，支撑件下端固定在底槽上的支撑板上。槽底制成波纹形。

Description

本发明涉及一种太阳能收集器，其中有一个整体深冲压无缝薄板金属收集槽（1），内装吸收板（9）和通有介质的集热管（12）和（13），槽的突缘（4）上装有的玻璃板盖（7）盖住薄板金属收集槽，用支撑件（17）顶住玻璃板盖（7）朝底的一面，将支撑件（17）分开一定距离均匀地压在槽底（3）上。
在已知的这类太阳能收集器（DE-OS3101298）中，收集槽的底部是平面形的。因而，虽然收集槽采用了无缝深冲压结构而且是自撑式的，但在太阳能收集器抽真空时，收集槽也会出现变形，使玻璃板盖承受负荷，从而产生应力，使玻璃板盖可能破裂。
本发明要解决的问题是进一步改进上述那种太阳能收集器，以便在太阳能收集器抽真空时出现的薄板金属槽变形不致产生应力导致玻璃板盖的破裂。
本发明描述的太阳能收集器解决了这个问题。
与本发明有联系的另一种太阳能收集器是把吸收板完全放在两块玻璃板之间，由US-PS    4186723可知，在平面凸缘内的板盖上设有相互汇合的穹顶状的拱形结构，以保证板盖不发生任何变形，防止板盖破裂。
可是按本发明制成的薄金属板槽底中，槽底发生膜盒效应。膜盒效应可以防止收集槽的弯曲变形和扭曲变形通过槽的侧面传递到玻璃板盖上。
如果把槽底的波纹沿平行于波纹方向即波峰波谷相互接替的方向延伸式薄板金属槽的侧面，这种效应还会进一步改善。
本发明的其它有益研制成果，在平行波向的薄板金属槽（1）侧面（2）上延伸的波纹向另外侧面延伸;薄板金属槽（1）的各侧面（2）的外形是凸形曲面;集热管（13）穿过的位置的侧面上有腹板（14），因而集热管（13）的通道出口位于与收集槽平面垂直的平面内;支撑件（17）安装在一个或多个条形金属板（18）上，条形金属板（18）架在槽底（3）的波峰上，支撑件（17）位于谷波上方;支撑件（17）安装在条形金属板（18）的中央区，条形金属板（18）向下的弯曲边缘跨接在两个相邻波峰之上。
在下文中介绍本发明的最佳实施例，并给出有关的附图，其中：
图1是真空太阳能收集器的局部部件分解透视图;
图2是集热管穿过收集器侧面的部位示意图;
图3是槽底上有支撑件的薄板金属条的布局示意图。

透视图1所示是一个具有矩形水平截面的真空太阳能收集器的一角。该收集器包括：由平面金属板材经深冲压加工成形的整体无缝箱形的收集槽1，其侧面2的外形为凸圆形;波纹板状的波纹形槽底3;平行于槽底的平面突缘4，突缘4上有一个环形密封圈6和环形沟槽5。这里所说的波纹是指垂直于波峰或波谷的任何截面大体上都呈现出相同的粗略正弦波形。突缘4上面的密封圈6放在辐照透明玻璃板盖7的下面，再用放在玻璃板盖上面的边框8把突缘4与密封圈6压紧并与突缘4连接好。
板盖7下面的收集槽内有一个辐照吸收板9，它由条形金属板10组成。这些金属板连在一起覆盖着槽的整个有效辐照区。通过折角部分11把各个吸收板成对地连接通有介质的集热管12的各个通道。集热管弯弯曲曲地布设在收集槽的有效辐照区上。集热管12的末端沿槽壁平行并与矩形槽短侧面平行走向的两个集热器13（入口和出口）连通。集热管之一示于图1。
如图2所示，集热管13穿过收集槽腹板14引出，腹板14又连在颈板15上，形成通道的出口，这些出口的平面都垂直于集热管13。
支撑件17支撑住玻璃板盖7。吸收板10上的支座孔16与支撑件以相等的间距分布在板盖上，支撑件17的下端固定在条形金属板18上，条形金属板18沿槽底3的波峰方向排列，其纵边缘稍向下弯曲。条形金属板18跨接在相邻两个波峰之上。支撑件17在条形金属板18上的分布方式是使支撑件的连接点处在波谷上方。这样，支撑件下方就留出了一个自由空间，以防止支撑件损坏槽底。支撑件17由于收集器抽真空而承受玻璃板盖7的压力。
图3再一次给出了纵边缘向下弯曲的条形金属板18的结构布局，以及安装在槽底上的支撑件17。
对于面积为1米×2米的太阳能收集器，沿收集器纵向的两个连续波峰之间的间距通常约为5厘米量级。收集槽的金属板厚度为1～2毫米。
收集槽1的侧面2的弯曲面可以做成连续的曲面，也可以由几个平面合成一个曲面。
实施例中说明的一种修改设计中，槽底波纹能平行于波的方向（即波峰波谷相互接替的方向）延伸到槽的侧面，从而提高了收集槽在深冲压加工后的尺寸稳定性。上述侧面是指矩形收集槽的长侧面。两个长侧面方向的波纹可延伸到两个短侧面上。因此在四周方向上两个短侧面也制成连续的波纹形。这就进一步增加了尺寸稳定性。
