翅柱式水冷CPU芯片散热器冷却与流动性能
Experimental study on cooling and flow performance of water-cooling radiator with different pin-fins structures for CPU cooling
摘要
Abstract
Heat dissipation performance and flow resistance of the traditional circular pin-fins radiator, the cylindrical column fins radiator with fluid guide plates at four corners and hydrofoil pin-fins radiator were studied by changing heat flux and cooling water flow. The pressure drop,chip temperature and thermal resistance of three radiators were measured under the same conditions. The results showed that the chip temperature of the radiator with fluid guide plates at four corners and hydrofoil pin-fins radiator are 65.5℃ and 55.5℃,respectively. The thermal resistance are 0.19K/W and 0.14K/W,respectively at heat flux of 80W/cm2 and flow rate of 20mL/s. The heat dissipation performance is better than traditional circular pin-fins radiator. At 60mL/s,the pressure drop of the cylindrical column fins radiator with fluid guide plates at four corners and hydrofoil pin-fins are 34kPa and 32kPa,respectively,which is less than traditional circular pin-fins radiator. Compared with the traditional one,the cylindrical column fins radiator with fluid guide plates at four corners and hydrofoil pin-fins radiator have better heat dissipation performance and smaller pressure drop.关键词
