A slim type pressure-gradient-driven low-pressure thermosiphon plate includes a main body closed by a cover. The main body includes a central heat receiving zone, a pressure accumulating zone and a first flow passage unit separately located at two opposite sides of the heat receiving zone, a free zone communicating with the pressure accumulating zone, a first and a second condensing zone communicating with the free zone, a third and a fourth condensing zone communicating with the first flow passage unit, a second flow passage unit located between and communicating with the first and the third condensing zone, and a third flow passage unit located between and communicating with the second and the fourth condensing zone. In the thermosiphon plate, a low-pressure end is created through proper pressure-reduction design to form a pressure gradient for driving steam-water circulation, and the working fluid can transfer heat without any wick structure.
