Abstract

The invention discloses a self-circulation efficient radiator, adopts a closed pipeline, does not need to be externally connected with cooling water for external circulation, facilitates reduction ofcooling cost and is convenient to operate. The radiator is characterized in that TiO2-water nanofluid is adopted as cooling agent, in the TiO2-water nanofluid, the concentration of TiO2 is optimal within the range of 0.2-0.5%, compared with tap water cooling agent adopted by a conventional radiator, a heat exchange coefficient can be increased by about 25%, moreover, a spiral rotating shaft capable of rotating automatically is arranged in a heat dissipation base plate, disturbance of the TiO2-water nanofluid in a pipeline is enhanced through continuous self-rotation of the spiral rotating shaft, the TiO2-water nanofluid is changed into turbulent flow from laminar flow, the heat dissipation capacity is improved to a large extent, and a heat exchange coefficient is increased by 50%.

Description

technical field [0001] The invention relates to a radiator, in particular to a self-circulating high-efficiency radiator. Background technique [0002] The power of the existing RF power supply is increasing continuously, ranging from thousands of watts to tens of kilowatts, but the size of the equipment is required to be more and more miniaturized, and the heat flux density of power devices has reached thousands of watts per square centimeter. The heating and heat dissipation of electronic components has become a major restrictive factor restricting the development of radio frequency power supplies and other high-power electrical equipment. Traditional water-cooled radiators are increasingly unable to meet the heat dissipation requirements of electronic components with higher heat flux. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] The purpose of the present invention is to provide a self-circulating high-e...
