Method and theory of 3D micro heat pipe cooling

introduction: The traditional heat dissipation method has included different parts, such as Air cooling and Water cooling. When IC chip generate heat in working on a high level, there has to be some methods to reduce heat make sure that the chips will not be damaged. With some theory [Surface area of evaporator, Heat input in Watt act.] there are several advanced method and theory of 3D micro heat pipe cooling.

Key word: LPMHP, Tube transfer ,Moore's Law ,Heat-Pipe, Fluids, Cooling rate.

Method and theory in experimental

A experimental study has been performed to investigate the heat transfer characteristics of looped parallel micro heat pipes of circular geometry having inner diameter of 1.8mm and length of 150mm placed parallel, connected by two U tubes of same diameter at the top and bottom ends. The experimental parameters are condenser inclination angel, heat input and properties of the working fluids. Taking acetone and ethanol as working fluids, heat transfer characteristics are determined experimentally for different condenser inclination angels a different heat input. With the advancement of micro and nanotechnologies, the power densities in the electronic equipments are increasing rapidly. Overheating of integrated circuit(IC),microchip etc. It is very important to facilitate optimum cooling of electronic components in a smaller electronic device because integrated circuit lifetime depends on the cooling rate. A heat pipe is a heat transfer mechanism that can transport large quantities of heat with a very small difference in temperatures between the hot and cold interfaces. Heat pipes are pencil-sized metal tubes that move heat from one end of the tube to the other without the aid of a pump. Within the heat pipe, heat vaporizes a small amount of fluid at the pipe’s hot end;…...

"It exploits his sickness, has nothing to do with his present needs, and shows an utter contempt for his own wishes. He's retired; can't you people respect that? He doesn't want to be a star.

The Last Leaf

...them both harder and ripped them to ribbons on their own floor. 4 The next morning I woke up at oh eight oh oh hours, my brothers, and as I still felt shagged and fagged and fashed and bashed and my glazzies were stuck together real horrorshow with sleepglue, I thought I would not go to school. I thought how I would have a malenky bit longer in the bed, an hour or two say, and then get dressed nice and easy, perhaps even having a splosh about in the bath, make toast for myself and slooshy the radio or read the gazetta, all on my oddy knocky. And then in the afterlunch I might perhaps, if I still felt like it, itty off to the old skolliwoll and see what was vareeting in the great seat of gloopy useless learning, O my brothers. I heard my papapa grumbling and trampling and then ittying off to the dyeworks where he rabbited, and then my mum called in in a very respectful goloss as she did now I was growing up big and strong: "It's gone eight, son. You don't want to be late again." So I called back: "A bit of pain in my gulliver. Leave us be and I'll try to sleep it off and then I'll be right as dodgers for this after." I slooshied her give a sort of a sigh and she said: "I'll put your breakfast in the oven then, son. I've got to be off myself now." Which was true, there being this law for everybody not a child nor with child nor ill to go out rabbiting. My mum worked at one of the Statemarts, as they called them, filling up the shelves with tinned soup and beans and all......
