Cylindrical heat pipe
WebNov 12, 2024 · (1) I think the easiest way is to use a Pipe block. Attach the right amount of thermal mass to the H port to represent the thermal mass of the granules. At the same time, estimate the hydraulic diameter and cross section area of your "pipe" so you get about right area for heat transfer with the granules. WebThe principle of operation of a simple cylindrical heat pipe is shown schematically in Fig. 2.1. The wick is saturated with a wetting liquid. In the steady state the liquid temp-erature in the evaporator is maintained higher than in the condenser by an external heat source. The resulting difference

WebMany applications involving convective heat transfer take place within pipes, tubes, or some similar cylindrical device. In such circumstances, the surface area of heat transfer normally given in the convection equation ( … WebIn the present work, the use of cylindrical turbulators in a double pipe heat exchanger has been investigated. Cylindrical fin type of turbulators has been placed circumferentially separated by 90° on the outer side of an inner pipe at a regular pitch. Experimental studies were undertaken for different air flow rates in a turbulent regime ...
WebA heat pipe-based thermal management system is proposed for a battery module with cylindrical cells. Compared with the natural cooling, the temperature of the battery can be significantly reduced by about 14 degrees C in the 5 C discharge rate. A thermal equivalent circuit model (TECM) is developed to describe the thermal behavior of the ... WebThe surface area (A) for transferring heat through the pipe (neglecting the pipe ends) is directly proportional to the radius (r) of the pipe and the length (L) of the pipe. A = 2 π r L As the radius increases from the inner wall to …
WebThe pressure recovery in a cylindrical heat pipe has been investigated. The experiments cover average radial Reynolds numbers between 5 and 150 and average Mach numbers up to the velocity of sound. During preliminary experiments in a cylindrical, gravity-assisted heat pipe at high Mach numbers large condensate flow instabilities were observed.
