Heat Pipes by Yuwen Zhang Pdf

"Heat pipes are efficient passive devices that can transfer large amounts of heat over long distances with small temperature differences between the heat sources and sinks by evaporation and condensation of the working fluid. Heat can be transferred without the use of any mechanically moving parts such as pumps and active controls in heat pipes. The vapor and liquid circulate in the conventional heat pipes, including thermosiphons, via evaporation/condensation and capillary or gravitational forces. For pulsating heat pipes, liquid slug and vapor plugs in the capillary tube oscillate due to evaporation and condensation. The effective thermal conductivity of a heat pipe can be three orders of magnitude higher than that of a copper rod with the same size. A heat pipe can find its applications in many sectors of industries, including electronics cooling, energy systems, spacecraft thermal control, permafrost cooling, and manufacturing. This book presents current research and development related to the design, applications and technology of various heat pipes, including conventional heat pipes and thermosyphon, pulsating heat pipes, loop heat pipes, and variable conductance heat pipes. Design tools based on computational fluid dynamics simulation and HSHPTM"--

Thermal Management Research Studies. Volume 2: Experimental Investigation of Oscillating Heat Pipes for Actuator Cooling by Anonim Pdf

Operation requirements of oscillating heat pipes (OHPs) were proposed. Based on the requirements, OHPs with acetone and nonflammable fluorocarbon fluids, FC-72 and FC-75, as the working fluid were developed. The OHPs had 40 tubing turns formed from a copper tubing with an inner diameter of 1.75 mm and a total length of 18.61 m. The OHPs were formed in the shape of a planer array that was 256-min wide and 446mm high. There were two condensers on both outer sides and one evaporator in the middle of the OHPs. Thermal performance tests were conducted at various operating temperatures and heat rates. The working fluid fill ratio was varied The OHPs with acetone and FC-72 exhibited their highest heat transport performance in excess of 2000 W without dryout. This is the first time that such a performance was demonstrated. The gravitational acceleration did not have noticeable influence on the performance of the OHPs. The thermal performances of the fluorocarbon OHPs were compared with the case of the acetone OHP.
