    • PURPOSE:To exchange heat by flowing both primary and secondary fluids by means of the driving of a pump on one fluid side by a method wherein an electromagnetic flow coupler is established between the primary and secondary fluids by applying magnetic field on the primary and secondary flow passages, the cross-sections of both of which are formed in an annular flow passage by arranging the primary flow passages and the secondary flow passages alternately. CONSTITUTION:An annular flow passage 42 is formed by arranging an inner tube 41 at the center of a cylindrical outer tube 40. A magnetic circuit is formed by axially arranging cylindrical magnets 43 onto the outer periphery of the outer tube 40 and by arranging a bar-shaped iron core 44 in the interior of the cylindrical tube 41. The flow passage 42 is divided by partition plates 45 into a plurality of primary and secondary flow passages 47 and 46 arranged alternately. When the secondary fluid forming ascending flows 52 is flowed in the secondary flow passages 46 by means of a secondary pump 8, the electric currents proportional to the flow speed of the secondary fluid are generated within the flow passage 46 portions in the annular flow passage, resulting in forming a loop electric current 63. Electrically conductive fluid in the flow passages 47 generates the fluidizing force, the direction of which is opposite to the moving direction of the secondary flow and which causes to form descending flows 60 by receiving the electric current 63 in the magnetic fluxes 62. The fluidizing forces generated in the flow passages 47 are compounded into the total pumping force of the primary fluid 61.
    • 目的:通过在一个流体侧驱动泵来流动主流体和次流体来交换热量,其方法是通过在主流体和次流之间施加磁场而在主流体和次流体之间建立电磁流耦合器 通道,通过交替设置一次流动通道和二次流动通道,两者的横截面形成在环形流动通道中。 构成:通过将内管41布置在圆筒形外管40的中心处形成环形流动通道42.磁路通过将圆柱形磁体43轴向布置到外管40的外周边上并且通过布置条 形状的铁心44在圆筒管41的内部。流动通道42被隔板45分成多个交替布置的一次和二次流动通道47和46。 当二次流体形成上升流52通过次级泵8在二次流动通道46中流动时,在环形流路中的流路46的部分内产生与二次流体的流速成比例的电流, 导致形成回路电流63.流路47中的导电流体产生与二次流的移动方向相反的流动力,并且通过接收电流63而形成下降流60 在流体通道47中产生的流化作用被复合到初级流体61的总泵送力中。
