Abstract

A heat pipe engine, comprising a housing (1), a shaft sleeve (4) disposed in the middle of the housing and fixedly connected with the housing, a spindle (5) disposed in the shaft sleeve through a bearing, and a combustion chamber (6) disposed outside the shaft sleeve and fixedly connected with the housing. A vortex generator (8) is connected at the end of the spindle, the vortex generator being in a truncated cone shape, and a plurality of conical helix shaped working medium passages (9) being provided on the vortex generator. According to the heat pipe engine, as the cone of the working medium passages is helix-shaped, a working medium moves along the helix; and as the working medium passages are 0.2-4 mm in diameter, the working medium can be divided into a plurality of small working medium flows. Thus a fluid boundary layer effect is made full use of to convert the energy of the working medium into the rotating kinetic energy for the spindle to be output. The heat pipe engine therefore has the advantages of high energy conversion efficiency and low energy consumption.
