摘　　要：本文针对余热利用中既需控制热源温度又需要对热量输入/输出进行管理的场合,提出了热管理器的概念。在运行过程中,热管理器可以实现对热源温度的控制,并根据各个用热对象的级别及工况,通过不凝性气体体积的变化,自动实现对热量输出的分配。为了验证热管理器的可行性,本文建立了实验样机及系统。实验结果表明,加热功率从6．0 kW上升至14．0kW,工质蒸汽温度的变化幅度仅为0．7℃。工质蒸汽/不凝性气体的交界面起到了良好的“热开关”作用。从热源回收的热量,按照优先级顺序依次分配给各个热用户。In the heat recovery process, temperature control of heat source is always required to ensure safety and high efficiency of the heat source equipment. In addition, thermal management is important for the proper use of waste heat. To this aim, the concept of Thermal Management Controller （TMC） was presented in this paper. Experimental prototype and the test system were established to validate its feasibility. The experimental results show that the prototype is effective in temperature control. The vapor temperature variation is only 0.7℃ when the heating power varies from 6.0 kW to 14.0 kW. In variable working conditions, the TMC can automatically adjust thermal＂ allocation to the heat consumer.
