In the present work a thermal pipe is modelled, designed by mathlab program 8.5 in order to use a heating mechanism through night or cloudy days in the cold climate. Heat transfer as geothermal energy from underground to the environment inside the greenhouse without loss any type of energy consumption but energy conservation. This technique is one of the latest applications of the heat transfer devices to transfer heat and energy. The heat transfer device is made of a sealed copper metal tube containing graphene oxide nanofluid as operation fluid. It is divided into three parts; the evaporator, adiabatic and condenser section. The active part of thermal device is the evaporator reign which transfers heat from the underground to the working fluid, which is in turn, transfers energy to the condenser part where it is dissipated to the surrounding of the greenhouse. This study was conducted on a greenhouse with an area of (12) m2. Mathematical model construct by applying the explicit technique when used the convergent values. Results show the heat transfer rates are increase, with stability, the environment temperature of the greenhouse when thermal heat transfer device is executed in the cold and cloudy period of the cold time. The temperature inside the greenhouse reached (25) ᵒC when thermal device inserted inside the soil to a level of (2.5) m with heat transfer rate of (500) W, while the outside temperature was about (15) ᵒC.
