Abstract

Oscillating heat pipe (OHP), as a heat transfer element, has a broad application prospect in the conversion and utilization of waste heat generated by mechanical equipment and thermal management of chip in intelligent manufacturing system. How to improve the heat capability of the OHP to enhance its applicability has always been a research hotspot. Liquid metal is used to improve the heat capability of the OHP in this paper. The evaporator, adiabatic and condenser lengths of the OHP are 40 mm, 51 mm and 64 mm, respectively. The effects of liquid metal volume fraction, heating power and angle on the start-up and heat capability of the OHP were studied experimentally. The results show that adding liquid metal will increase the start-up temperature and start-up time. When the heating power is greater than 100W, liquid metal can enhance the heat capability of the OHP, and the thermal resistance first decreases and then increases with the increase of the volume fraction of liquid metal. When the OHP is placed vertically and the heating power is 350W, compared with the pure ammonia OHP, the heat capability of the OHP with liquid metal volume fraction of 2.43% is enhanced by 10.45%.
