Experimental Investigation on Flow Characteristic of Inclined Evaporator of Separate Type Heat Pipe

The separate type heat pipe is featured its provision of evaporator arranged with slight lean. With this characteristic feature, the heat pipe provides several important advantages. In order to determine working characteristics of the inclined evaporator, a series of experiments were performed by making a unit with an evaporator. A flow visualization study of the inside flow phenomena of an inclined evaporator at several angles has been conducted. This paper describes the inclined angle, heat flux, the quantity of working fluid, and pressure. Water was charged as the fluid. Flow phenomena were recorded with a still camera.
