Abstract:
1. A slim type pressure-gradient-driven low-pressure thermosiphon plate, comprising: a main body including a heat receiving zone arranged near a central area thereof, 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 condensing zone and a second condensing zone communicating with the free zone, a third condensing zone and a fourth condensing zone communicating with the first flow passage unit, a second flow passage unit located between the first and the third condensing zones to communicate the first condensing zone with the third condensing zone, and a third flow passage unit located between the second and the fourth condensing zone to communicate the second condensing zone with the fourth condensing zone; wherein the first flow passage unit includes a plurality of first flow passages and a plurality of first flow-guiding members, the first flow-guiding members being arrayed to space from one another, and the first flow passages being respectively formed between two adjacent first flow-guiding members; and wherein the second flow passage unit includes a plurality of second flow passages and a plurality of second flow-guiding members, the second flow-guiding members being arrayed to space from one another, and the second flow passages being respectively formed between two adjacent second flow-guiding members; and wherein the third flow passage unit includes a plurality of third flow passages and a plurality of third flow-guiding members, the third flow-guiding members being arrayed to space from one another, and the third flow passages being respectively formed between two adjacent third flow-guiding members; wherein the first flow-guiding members are respectively substantially V-shaped ribs configured to accumulate pressure without capillary pumping action and further to form three V-shaped rib sets; the three rib sets being located in a same plane and parallel with each other: a first gap being formed between the two adjacent V-shaped rib sets without any barriers therebetween; the V-shaped ribs respectively including a first vertex, a first edge and a second edge, and the first and the second edge of each of the V-shaped ribs meeting with each other at the first vertex; the first flow passages being respectively formed between two adjacent V-shaped ribs; and a cover being correspondingly closed onto the main body.
