The invention relates to a bath condenser with a condenser block (1) that has evaporation passages (8) for a liquid and liquefaction passages (2) for a heating medium and at least two circulation sections (7) that are located vertically on top of one another. The evaporation passages (8) each have on the lower end of a circulation section (7) at least one entry opening (9) for the liquid and on the upper end of a circulation section (7) at least one exit opening (10), for each circulation section (7) there being a liquid storage tank (15) that is flow-connected to the entry opening (9) and the exit opening (10) of the circulation section (7) and that has a gas offtake (18). The inlet into the gas offtake (18) is not located in the area in front of the side (12) of the circulation section (7) in which the exit opening (10) of the circulation section (7) is located.
A bath condenser according to claim 1, wherein the inlet into the gas offtake (18) is located in the half-open volume next to the condenser block (1) that is bordered by the side (11) of the condenser block (1) that is adjacent to the side (12) of the circulation section in which the exit opening of the circulation section is located, and by two half-planes that each include one vertical edge of the adjacent side (11) and that are aligned perpendicular to the adjacent side (11).
A bath condenser according to claim 1, wherein the inlet into the gas offtake (18) is located in the half-open volume next to the condenser block (1) that is bordered by the side of the condenser block (1) opposite the side (12) of the circulation section (7) in which the exit opening (10) of the circulation section (7) is located, and by the two half-planes that each include one vertical edge of the opposite side and that are aligned perpendicular to the opposite side.
A bath condenser according to claim 1, wherein at most two sides (12) of the condenser block (1) are provided with entry (9) and/or exit openings (10).
A bath condenser as claimed in claim 1, wherein a collector (13) with a liquid feed line (22) and a gas offtake (18) that covers the sides of several circulation sections (7), preferably the entire side (12) of the condenser block (1), is attached to one side (12) of the condenser block (1) in which the entry (9) and/or exit openings (10) are located.
A bath condenser according to claim 1, wherein the condenser block has a rectangular cross-section and is located in a round tank.
A bath condenser according to claim 1, wherein the condenser block (1), liquid storage tanks (20) and separation spaces (21) that are connected to the liquid storage tanks (20) form in a plan view, a hexagon.
A bath condenser according to claim 1, wherein the condenser block (1), liquid storage tanks (20) and separation spaces (21) that are connected to the liquid storage tanks (20) form in a plan view, an octagon.
