引言已经报道过使用磁流体直接转换能量的想法,但由于转换效率很低,报道实际转换能量系统的论文不多。我们报道的自动冷却装置(ACD)可利用部分废热使流体循环从而消除机械废热。这种冷却装置的操作自动地受热源的热作用的控制。本文讨论利用磁化强度主要取决于温度的温度传感磁流体的冷却装置的性能。其冷却特性决定于磁流体的热性能和磁性能,最大冷却能力主要由外加磁场的强度来决定。
INTRODUCTION The idea of using magnetic fluids to directly convert energy has been reported but, due to the low conversion efficiency, there are few papers covering the actual conversion of energy systems. The automatic cooling unit (ACD) that we report can utilize some of the waste heat to circulate the fluid to eliminate mechanical waste heat. The operation of such a cooling device is automatically controlled by the thermal effect of the heat source. This article discusses the performance of a cooling device that utilizes a temperature-sensing magnetic fluid whose magnetization depends primarily on temperature. The cooling characteristics of the magnetic fluid depends on the thermal performance and magnetic properties, the maximum cooling capacity is mainly determined by the strength of the applied magnetic field.
