Closed loop system for maintaining constant temperature
专利汇可以提供Closed loop system for maintaining constant temperature专利检索，专利查询，专利分析的服务。并且The fluid-filled closed loop system maintains a temperature stable platform, having dynamically operated electronic devices such as power transistors secured thereto, at a constant predetermined temperature. In addition to the platform, the system comprises a heater positioned below the platform and a reservoir and associated heat exchanger positioned above the platform. A continuous multi-section conduit circuit couples the output of the heater to the reservoir and thence to an input of the heat exchanger, and is in thermal contact with a surface of the temperature stable platform. Vapor bubbles formed in the heater rise in the conduit circuit section contacting the platform, are released from the surface of the liquid in the reservoir, and are condensed by the continuously operated heat exchanger. The system also comprised a temperature controlled solenoid valve at the output of the heat exchanger, and a return conduit section coupled from the valve to an input of the heater. The valve which is responsive to the temperature of the platform, opens when the temperature exceeds a predetermined value thereby providing cooled liquid for the heater which in turn lowers the temperature of a liquid in the fluid conduit and platform. When a small temperature decrease occurs, the valve closes and the temperature of the platform increases. This cyclic operation continues and the temperature of the plat- form is controllable to within fractions of a centigrade degree.，下面是Closed loop system for maintaining constant temperature专利的具体信息内容。
