Abstract:
1. A condenser for condensing a refrigerant gas by rejecting heat of said gas to a column-shaped heat absorption portion of an exterior cooling device, the condenser comprising: (a) a condensing portion formed of a flat plate shaped to surround and fixed to the entire periphery of said column-shaped heat absorption portion, said condensing portion having a plurality of parallel through holes formed along the circumferential direction and opening through opposite end faces of the plate; (b) an inlet portion formed by a first hollow tube having a closed end, an open end connected to a refrigerant inflow passage, and an opening trough the circumferential side wall of the first hollow tube, the first hollow tube being connected at the side wall opening to a first one of the opposite end faces of said condensing portion and communicating with the parallel holes; and (c) an outlet portion formed by a second hollow tube having a closed end, an open end connected to a refrigerant outflow passage, and an opening through the circumferential side wall of the second hollow tube, the second hollow tube being connected at the side wall opening to a second one of the opposite end faces of said condensing portion and communicating with the parallel holes, the cross is sectional area of the outflow passage being smaller than the cross sectional area of the inflow passage.
