BONDING SHEET AND MANUFACTURING METHOD THEREOF, AND HEAT DISSIPATION MECHANISM AND MANUFACTURING METHOD THEREOF is an invention by Akio KAWABATA, Kawasaki JAPAN. The heat-pipe has excellent heat conduction and temperature uniformity capabilities. Transfer of energy from a more concentrated form (Hotter) to less concentrated form (Colder) simply is heat dissipation. In residential heating, convection is the mechanism by which heat is lost by warm air leaking to the outside when the doors are opened, or cold air leaking into the house through the cracks or openings in walls, windows, or doors. The drive motor can better dissipate heat through the heat-pipe. The mechanisms of heat flow not only influence the heating and cooling systems we install but also inform how we build the “thermal separation” between indoors and outdoors. Heat generation is the thermal resistance times the power consumption, and so by dividing the allowable heat generation by the thermal resistance, the power consumption that can be allowed, that is, the power dissipation is obtained. opposite inlet and outlet cavity cold plate cooling systems with simple structure are established.
