Abstract:
A thermosyphon using a working fluid therein, comprising:a) an evaporator having a front face, a back face, a top and a bottom, the evaporator comprising a plurality of cooling fins and at least one working fluid flow path having an inlet adjacent the bottom and an outlet adjacent the top, the at least one working fluid flow path spiraling throughout the fins of the evaporator from the inlet to the outlet such that first tubular sections of the flow path pass adjacent the front of the evaporator and second tubular sections of the flow path pass adjacent the back of the evaporator, the first and second tubular sections being interconnected by a plurality of hairpin turns on sides of the evaporator; b) a condenser disposed above the evaporator, the condenser having a front face, a back face, a top and a bottom, the condenser comprising a plurality of cooling fins and at least one working fluid flow path having an inlet adjacent the top and an outlet adjacent the bottom, the at least one working fluid flow path spiraling throughout the fins of the condenser from the inlet to the outlet such that first tubular sections of the flow path pass adjacent the front of the evaporator and second tubular sections of the flow path pass adjacent the back of the evaporator, the first and second tubular sections being interconnected by a plurality of hairpin turns on sides of the condenser; c) first piping connecting the outlet of the evaporator working fluid flow path to the inlet of the condenser working fluid flow path, whereby working fluid evaporated in the evaporator is communicated from the evaporator to the condenser; and d) second piping connecting the outlet of the condenser working fluid flow path to the inlet of the evaporator working fluid flow path, whereby working fluid condensed in the condenser is communicated from the condenser to the evaporator.
