| dc.description.abstract | With the impact of global climate change being felt in recent years, efforts to transition to a green economy have started to gain momentum all over the world, especially in European countries. In this context, it is aimed to evaluate the production of energy in terms of sustainability; and to make its use economical and efficient. For this, first of all, especially in the energy-intensive industrial sector; Attention is paid to ensure that all kinds of devices and equipment produced are systems with high energy efficiency and long life. With the technological progress in the electronics industry sector in recent years; decrement in size and volume. However, although high-tech products in small volumes are advantageous for users; This creates a troublesome situation for producers, which means more heat is produced in unit volume. This situation necessitates the use of more effective cooling techniques in electronic devices. The cross-flow cooling method, which is used to increase heat transfer from electronic elements, is one of the most widely used methods. This method is based on the principle of sending the cold fluid over all the components with a fan, thereby cooling the entire electronic components. Another method of heat transfer is impinging jet cooling where cold fluid is locally sprayed onto an element with a high temperature with a nozzle. For this reason, it is difficult to reach the conditions that can keep the whole circuit safely with a single type of cooling method. Implementing the impinging jet and cross flow cooling method together can create a beneficial situation with high cooling capacity. Although Al2O3-Water nanofluid is a heat transfer fluid used extensively in heat transfer research; In the literature research reached, it has been determined that the number of jet flow studies in which cross flow and impinging jet flow are applied together is quite low. | tr |
