Abstract

Like other computer hardware components, the central processing unit (CPU) generates heat during operation and requires effective cooling to maintain optimal performance. One of the most efficient methods for cooling a CPU is the use of a liquid-based cooling system. This system typically consists of three main components: a fluid block that makes direct contact with the CPU, a pump, and a heat exchanger, which includes a fan and a radiator. The coolant circulates through the system via connecting pipes. In this study, the thermal and hydraulic performance of a CPU cooler was analyzed under various operating conditions. Water was used as the working fluid (coolant) in the system. A 100 W thermoelectric heater was employed to simulate the thermal load and to determine the cooling capacity of the system. The volumetric flow rates of the coolant were set to 1, 2, 3, and 4 L/min, respectively. It was observed that the heat transfer between the CPU surface and the cooler decreased with increasing fluid velocity. The fluid pressure was higher at the inlet of the cooler and decreased along the flow path, depending on both the geometry of the flow channels and the flow rate of the coolant. For effective heat dissipation in CPU cooling systems, it is crucial to maintain the coolant flow rate and velocity within an optimal range.

Özet

Diğer bilgisayar donanım bileşenlerinde olduğu gibi, merkezi işlem birimi (CPU) de çalışırken ısı üretir ve maksimum performansla çalışabilmesi için etkili bir şekilde soğutulması gerekir. CPU’yu soğutmanın en etkili yöntemlerinden biri sıvı bazlı bir soğutma sistemi kullanmaktır. Bu sistem genellikle üç ana bileşenden oluşur: CPU ile doğrudan temas halinde olan bir sıvı bloğu, bir pompa ve fan ile radyatörden oluşan bir ısı değiştirici. Soğutucu akışkan bu sistemde borular aracılığıyla dolaşır. Bu çalışmada, bir CPU soğutucusunun termal ve hidrolik performansı farklı çalışma koşulları altında analiz edilmiştir. Soğutucu akışkan olarak sistemde su kullanılmıştır. Soğutma kapasitesinin belirlenebilmesi amacıyla 100 W’lık bir termoelektrik ısıtıcı kullanılmıştır. Sıvının hacimsel debileri sırasıyla 1, 2, 3 ve 4 L/dk olarak ayarlanmıştır. Akışkan hızı arttıkça CPU yüzeyi ile soğutucu arasındaki ısı transferinin azaldığı gözlemlenmiştir. Farklı hacimsel debilerde, akışkan basıncı soğutucu girişinde daha yüksek olmuş; bu basınç, hem CPU soğutucusunun akış kanalı geometrisine hem de akışkan debisine bağlı olarak sistem boyunca azalmıştır. CPU soğutma sistemlerinde etkili bir ısı transferi sağlanabilmesi için soğutucu akışkanın debisinin ve hızının uygun bir aralıkta tutulması gerekmektedir.
