Abstract

The invention based on the following: Expansion /shrinkage that causing big force resulted from two phases of thermal effects; 1st is expansion, resulting when inject any hot fluid (HTF heat transfer fluid) inside a metal pipe, to do expansion; 2nd shrinking, when it is cool by inject any cooled HTF. When applied this alternatively heat/cool thermal process for these metal rods pipes as described in shown mechanism in Fig 1 this will producing alternated two linear kinds of forces. The designed Invention of Longitudinal Expansion /shrinkage Engine system (EGT1) that shown in Fig 4-1 based on applying heat/cooling process to a metal element that causing expansion/shrinkage process consequently to part no. (1) in Fig 1. Also Fig 1 had shown many TEs that can also install any numbers of it to gain any required power. The designed Invention of Longitudinal Expansion /shrinkage Engine system (EGT1) that shown in Fig 1 can be used by insert in any kind of thermal systems as shown in Fig 3-1 c such as:- Nuclear, fuel, coal, solar or any kind of thermal system.

Description

Technical Field: thermal expansion/shrinkage engines
Background Art: our previous invented system that was based on metal thermal expansion/shrinkage process due to effect from HTF heat transfer fluid Named (Expansion/Shrinkage Engine) was recorded in Cairo/Egypt patient office EGPO 11/June/2012 ref no. 1070/2012
Disclosure of invention
Most solids expand when heated. The reason of this is the heating gives the atoms more room heat bounce about the large amount of kinetic energy. Thermal expansion is a relatively small effect which is approximately linear.
Scientific backgrounds formulas.
Expansion length (AH :- Suppose an metal object see Fig 2 has an initial length Lo along some direction at some temperature changing= ΔΤ and that the length increase my an total amount AL
A L= a Lo AT
Lo: initial length, AL: length increase, AT: change in temperature, a proportionally constant is called the average coefficient of linear expansion for a given material and has units of (° C) "1.
Force:-. Two kinds of gained forces
*1S is expansion, resulting when inject any hot fluid (HTF heat transfer fluid) inside a metal pipe, to do expansion.
*2nd is shrinking, when it is cool by inject any cooled HTF.
When applied this alternatively heat/cool thermal process for these metal rods pipes as described in shown mechanism Fig 1 this will producing alternated two linear kinds of forces.
F=Fe=Fs=A.E. AL/I N
Fs: shrinkage force. Fe: expansion force, F: the gained force whatever shrinkage or expansion, E: Young's Modulus
Then Work done W :-Since we using both Fe, Fs the work done will be double and the efficiency too will become double that mean also costs and losses will decrease,
: W=2F. AI Watt or j/s
The designed Invention of Longitudinal Expansion /shrinkage Engine
system (EGT1) that shown in Fig 1 based on applying heat/cooling process to a metal element that causing expansion/shrinkage process consequently to part no. (1 ) In Fig 1
Also Fig 1 had shown many TEs that can also install any numbers of it to gain
any required power.
The designed Invention of Longitudinal Expansion /shrinkage Engine
system (EGT1) that shown in Fig 1 can be used by insert in any kind of thermal systems as shown in Fig 3-1c such as:- Nuclear, fuel, coal, solar or any kind of thermal system.
