Plastic injection molding is one of the widely used methods of forming plastic materials. The process of cooling the mold in injection molding has an important role in reducing the production costs and increasing the product quality. Thanks to the evolving add…

Refrigeration and air-conditioning systems consume about 15% of global electricity, and 46% of energy used in household and commercial buildings belongs to heating, ventilation and air-conditioning (HVAC) systems. Vapor-compression technologies dominate the HV…

In last years, the use of alternative energy sources such as solar energy has become even more important because of environmental problems, especially the rapid depletion of fossil energy resources. There are works done for this purpose and solar energy applic…

Elektronik kartlarda meydana gelen yüksek ısı üretimi, kart üzerindeki bileşenlerin çalışma performansını ve kullanım ömrünü etkileyen önemli bir parametredir. Bu nedenle cihazların mekanik tasarımları yapılırken soğutmayı sağlamaya yönelik çalışmalar yapılmal…

The cell temperature of a photovoltaic (PV) module increases with increasing irradiation rate, and this increment adversely affects the output power or the electrical efficiency of the PV module. Therefore, in the present study, a series of experiments are p…

Plastic injection molding is a manufacturing process of heating plastic granules and forcing melted plastic into a mold cavity and removing from the mold after cooling. One of the most important elements in the production of parts by plastic injection molding …

This study examines the failure mechanisms of a three-phase AC induction electric motor with a closed body design, intended to provide IP protection, due to insufficient cooling under high-temperature conditions. Overheating at elevated temperatures adversely …

In this study, a thermoelectric generator (TEG) system is designed for the generation of electricity from solar energy. A temperature difference between surfaces of TEG must be achieved for electricity generation. Heating is provided by a solar-powered two-p…

Cooling process applied to complete sintering cycle of aluminum composites produced by hot pressing method has a great effect on grain size, hardness and wear resistance. In order to obtain a fine-grained microstructure, increase hardness and reduce amount of …

In this study, the effect of still water cooling on electricity generation in a thermoelectric generator heated by solar energy heat pipe is experimentally investigated. For this purpose, a heat pipe with ethyl alcohol as the working fluid has been manufacture…

Beginning from the 20th. Century, Architectural designs and plans are became more complex because of the increasing of functional needs. This appeared an orientation problem for users of the big complex buildings like hospitals, airport, shopping mall, etc. …

For a successful thermal performance, the right choice and design of the thermal management materials used in LED die-moulding, cooler and soldered parts is a critical engineering problem. Because they are affected by heat emitted from the pn junction in the L…
