    • A high temperature electrical insulation system is provided by forming a winding in an electrical device from a conductor that is pre-coated with a first layer of at least partially cured inorganic material. A second layer of inorganic material is applied, either during or just prior to forming the winding, over the first layer in order to seal any cracks in the first layer. The resultant electrical insulative coating is cured following the forming process, essentially at room temperature. The insulation system provided is thus totally inorganic, and its manufacture does not require the use of organics, or heating to high temperatures to cure the coating or to cause pyrolysis and/or volatilization of organic elements, as did prior electrical insulation systems. Furthermore, because no organics are utilized in either the manufacture or operation of the insulation system, there is no residual carbon in the resultant coating. The problem of reduced dielectric strength--caused by residual carbon--which plagued some prior attempts to develop polymer based high temperature insulation systems, is thus eliminated. By utilizing only inorganic materials, the insulation system provided is capable of operating satisfactorily for extended periods of time at temperatures in excessof 500.degree. F.
    • 通过从预先涂覆有第一层至少部分固化的无机材料的导体在电气装置中形成绕组来提供高温电绝缘系统。 在形成绕组之前或之前,在第一层上施加第二层无机材料,以密封第一层中的任何裂纹。 所得的电绝缘涂层在形成过程之后固化,基本上在室温下固化。 因此,所提供的绝缘系统是完全无机的,并且其制造不需要使用有机物,或者加热到高温以固化涂层或者引起有机元件的热解和/或挥发,如现有的电绝缘系统。 此外,由于在绝缘系统的制造或操作中没有使用有机物,所以在所得的涂层中不存在残留的碳。 因此消除了由残留碳引起的降低的介电强度的问题,其困扰了先前尝试开发基于聚合物的高温绝缘系统。 通过仅使用无机材料,所提供的绝缘系统能够在超过500°F的温度下长时间工作。

    • A solar collector is provided that is formed from relatively thin polymer sheet(s). The sheet(s) are welded together to integrally define a storage tank, a plurality of fluid flow channel (e.g. risers), and other desired features within the collector. The storage tank is located at a first end of the panel and a heat exchanger is provided within the storage tank. The heat exchanger is arranged to transfer heat from the storage tank to a target fluid (such as water) that is to be heated or preheated by the collector. The collector is arranged so that when it is installed, the collector may be positioned with the storage tank located generally above the fluid flow channels. The storage tank and the fluid flow channels are arranged such that when the collector is installed and filled with a working fluid, a thermosiphon effect will cause the collection of hot water within the storage tank.
    • 提供由相对薄的聚合物片形成的太阳能收集器。 焊盘被焊接在一起,以一体地限定存储箱,多个流体流动通道(例如立管)和收集器内的其它期望的特征。 储罐位于面板的第一端,并且在储罐内设置热交换器。 热交换器被布置成将热量从储罐传递到由收集器加热或预热的目标流体(例如水)。 收集器布置成使得当其被安装时,收集器可以被定位成使得储存罐大致位于流体流动通道的上方。 存储罐和流体流动通道布置成使得当收集器被安装并填充有工作流体时,热虹吸效应将导致储存罐内的热水的收集。
