The present invention provides a loop thermosiphon including an evaporator and a condenser interconnected in flow communication by a vapor conduit and a condensate conduit. A wick is disposed in a portion of the evaporator and a portion of the at least one condensate conduit adjacent to the evaporator to facilitate capillary action to cycle a coolant fluid through the loop thermosiphon. Advantageously, a porous valve is lodged within the condensate conduit so that a first pressure on a condenser side of the porous valve is greater than a second pressure on an evaporator side of the porous valve. In this way, a portion of the liquid coolant fluid disposed within the loop thermosiphon is forced through the porous valve and a remaining portion is forced through the at least one condenser. In one embodiment, the porous valve comprises a plug of sintered material that is lodged within the condensate conduit so as to provide a seepage of coolant fluid during periods of low thermal energy transfer to the evaporator so as to avoid drying out of the system. om the first side of the rotor shell plate and a second pair of axially spaced tabs extending from the second side of the rotor shell plate, step (b)(ii) further comprising the step of inserting the first pair of tabs of the rotor shell plate into the first and fourth openings of the first diaphragm plate and inserting the second pair of tabs of the rotor shell plate into the second and third openings of the second diaphragm plate. 4. The method of claim 3 wherein the outboard end portion of each diaphragm plate further defines a fifth opening extending from the outboard and hot ends, the locating means of the hot end rotor angle comprises a tab extending from the first side and a tab extending from the second side, step (b)(ii) further comprising the step of inserting the tab extending from the first side of the hot end rotor angle into the fifth opening of the first diaphragm plate and inserting the tab extending from the second side of the hot end rotor angle into the fifth opening of the second diaphragm plate. 5. The method of claim 4 wherein the outboard end portion of each diaphragm plate further defines a sixth opening extending from the outboard and cold ends, the locating means of the cold end rotor angle comprises a tab extending from the first side and a tab extending from the second side, step (b)(ii) further comprising the step of inserting the tab extending from the first side of the cold end rotor angle into the sixth opening of the first diaphragm plate and inserting the tab extending from the second side of the cold end rotor angle into the sixth opening of the second diaphragm plate. 6. The method of claim 4 wherein each intermediate portion defines seventh, eighth, ninth, tenth, and eleventh axially spaced openings, the locating means of each stay plate comprises a trio of tabs extending from the first side of the stay plate and a pair of tabs extending from the second side of the stay plate, step (b)(ii) further comprising the step of inserting the trio of tabs into the seventh, eighth, and tenth openings of the first diaphragm plate and inserting the pair of tabs into the ninth and eleventh openings of the second diaphragm plate. 7.
