Heat pipe and method of manufacturing the same
TLDR
In this paper, a wick layer is attached and fixed to one surface of a metal tape without forming a gap with the metal surface, and thereafter, the tape is rolled so that the surface having the wick layers serves as an inner surface, thus forming a pipe shape, then the pipe wall is corrugated.Abstract:
A wick layer is attached and fixed to one surface of a metal tape without forming a gap with the metal surface, and thereafter, the tape is rolled so that the surface having the wick layer serves as an inner surface, thus forming a pipe shape, then the pipe wall is corrugated. According to the above process, the wick layer is completely and uniformly attached to the inner surface of the heat pipe.read more

Flexible heat pipe
John H. Rosenfeld,Nelson J. Gernert,David B. Sarraf,Peter J. Wollen,Frank C. Surina,John E. Fale +5 more
TL;DR: In this article, a very flexible heat pipe is constructed of multiple layers of material laminated into the final structure, and the center of the symmetrical structure is a coarse screen which creates a vapor space.
Patent
Method of forming a phase change heat sink
TL;DR: In this paper, a phase change passive heat sink with a base member and heat dissipating members is presented, where the base member is hollow and defines an evaporation chamber therein.
Patent
Stacked low profile cooling system and method for making same
TL;DR: In this paper, a stacked array of low profile heat pipes with a plurality of micro tubes extended therethrough are placed into thermal connection with heat producing components, and a heat transfer fluid is contained in the micro tubes of the low-profile heat pipes and removes the heat from the heat producing component.
Patent
Toroidal low-profile extrusion cooling system and method thereof
TL;DR: In this article, a toroidally shaped LPE with a plurality of microtubes extending through the LPE is disclosed, and a heat transfer fluid is contained in the micro-tubes of LPEs and removes the heat from the heat producing components.
Patent
Turbulating heat exchange tube and system
Jerry M. Hougland,Lloyd F. Hay +1 more
TL;DR: In this paper, the turbulating structures are deformed into the tube and have smoothly sloping side walls which further inhibit the dimples from preventing full drainage of the tube, and the tubes are fixed to the apparatus at an angle which provides a drainage slope.

Advantageous configuration of tubing for internal boiling
J Withers,H Dean,S Ross +2 more
TL;DR: In this article, the axial pitch P of adjacent convolutions was not greater than 3/4 inch, the depth d of the ribbing being between 1/64 and 3/64 inch, and the ratio P/d being between 5 and 25.
Patent
Self-damping convoluted conduit
James M. Lalikos,Harold K. Waite +1 more
TL;DR: In this paper, the authors propose to construct a manifold of coaxially nesting tubes which cooperate to form a wall thickness variable variable wall thickness, which is achieved by wrapping tape in successive layers to form multiple layered wall.

Construction of a heat transfer wall and heat transfer pipe and method of producing heat transfer pipe
Yoshiyuki Satoh,Tomio Higo +1 more
TL;DR: In this article, a method of producing heat transfer pipes comprises the steps of rolling the outer surface of a pipe to form spiral fins integral with the pipe wall, and urging a sharp edged rolling tool against the inner surface of the pipe while rotating the tool on the outer surfaces of the pipeline along a spiral path having a lead angle which is in reverse relation to the lead angle of the fins so as to form breaks in the fins at predetermined intervals.
