旋涡形太阳灶主要由螺旋形平板聚光器构成,这种聚光器结构简单,加工容易,成本较低,受到了广泛的重视。本文对它的原理和加工等问题进行一些讨论。 一、原理 螺旋形平板聚光器主要由反光螺旋带条和固定反光螺旋带条的平板刚架组成,后者可用等角度分布(例如30°)的辐射形架代替(图1)。它很象一块比较厚的“板”。设平板刚架的厚度为d,则聚光器的结构厚度D为
Whirlpool solar cookers mainly by the spiral plate condenser composition, this condenser structure is simple, easy processing, low cost, has received widespread attention. This article discusses some of its principles and processing issues. First, the principle of spiral plate concentrator mainly by the reflective spiral ribbon and fixed reflective spiral ribbon plate rigid frame, the latter can be used with the angular distribution (such as 30 °) radiating frame instead (Figure 1). It resembles a relatively thick “plate.” Let the thickness of the plate rigid frame d, then the structure thickness D condenser
