Heat pipe used for cooling applications - where pipe is bent to avoid negative slope, and contains baffles guiding flow of working liq. and its vapour, esp. water and steam

摘要

An outer pipe (a) is sealed at both ends and contains a coaxial pipe (b) which is open at both ends. The two pipes (a,b) are bent at one point along their length to form a pipe elbow with a hot end (a1) and a cold end (a2). End (a1) contains a wick receiving a working liq., e.g. water, which is evaporated at end (a1), so the vapour flows through the bore of pipe (b) to the cold end (a2) where condensn. occurs. End (a2) is surrounded by at least one reservoir for the condensate; and this reservoir is connected to the bore of pipe (b) by a hole, and pref. also by a vent at a higher level than the hole. - Efficient sepn. of the working liq. from its vapour, e.g. water from steam, esp. at start-up is obtd.
