A working fluid for heat pipe includes a liquid and a plurality of nano-sized particles dispersed in the liquid. The liquid has a surface tension increasing with increasing temperature in a working temperature range of the heat pipe. The working fluid for heat pipe has a surface tension increasing with increasing temperature in a working temperature range of the heat pipe can avoid capillary limit of the heat pipe reducing at operating temperature range of the heat pipe. The nano-sized particles dispersed in the working fluid have high thermal conductivities, and the performance of the heat pipe can be enhanced.
