Abstract:
1. A thermal siphon structure comprising: a main body; a chamber disposed in the main body; a lower layer comprising an evaporation section arranged in the chamber on one side thereof, the evaporation section having multiple spaced, continuous first flow guide sections, each of the first flow guide sections having multiple serially arranged first flow guide bodies, each of the first flow guide bodies being transversely arranged at spaced intervals to define between adjacent pairs of guide bodies a plurality of first flow ways, the first flow ways having a horizontal shape having a continuous series of sections, each having a first narrower end and a first wider end, the first wider end of each first flow way section corresponding to the first narrower end of another separate adjacent first flow way section, an end of each series of first flow ways communicating with at least one open area and a guide section comprising a pair of symmetrical opposed guide portions including a first guide portion and a second guide portion, wherein the first guide portion and the second guide portion are generally V-shaped structures, located between the first flow guide bodies and the at least one open area and extend from the two opposite walls of the chamber toward a center so as to form a narrowed necked opening between the evaporation sections and the open area, the guide portions containing a plurality of spaced members aligned parallel to the walls of the chamber; an upper layer comprising a condensation section arranged in the chamber on the other side thereof opposite to the evaporation section, the condensation section having multiple second flow guide sections, each of the second flow guide sections having multiple second flow guide bodies, the second flow guide bodies being transversely arranged at spaced intervals to define between adjacent pairs of guide bodies a plurality of second flow ways, the second flow ways having a series of sections each having a second narrower end and a second wider end, the second wider end of each second flow way section corresponding to the second narrower end of another adjacent second flow way section; and a connection section arranged between and separating said upper layer and said lower layer the evaporation section and the condensation section in the chamber, the connection section having a set of first communication holes and a set of second communication holes in communication with the evaporation section and the condensation section respectively.
