Abstract

A condenser having improved condensation performance is provided. The condenser includes a plurality of cooling pipes, being disposed in a chassis to which the steam is introduced, through the interior of which cooling water used for heat exchange with steam flows; an inner channel that extends in a top-bottom direction and that is surrounded by the plurality of cooling pipes; a plurality of pipe-supporting plates disposed at a distance from one another in a direction in which the plurality of cooling pipes extend to support the plurality of cooling pipes; and a water receiving portion disposed between the plurality of pipe-supporting plates and being inclined downward from one pipe-supporting plate to the other pipe-supporting plate.

Claims (11)

1. A condenser comprising:

a plurality of cooling pipes, being disposed in a chassis to which a steam is introduced, through the interior of which cooling water used for heat exchange with the steam flows;

an inner channel that extends in a top-bottom direction and that is surrounded by the plurality of cooling pipes;

a plurality of pipe-supporting plates disposed at a distance from one another in a direction in which the plurality of cooling pipes extend to support the plurality of cooling pipes; and

a water receiving portion disposed between the plurality of pipe-supporting plates and being inclined downward from one pipe-supporting plate to the other pipe-supporting plate.

2. The condenser according to claim 1 , wherein the water receiving portion is provided inside the inner channel.

3. The condenser according to claim 1 , wherein the water receiving portion is a plate-like member that is bent in a substantially V shape in a sectional view substantially parallel to the pipe-supporting plates.

4. The condenser according to claim 3 , wherein the plate-like member of the water receiving portion has a through-hole penetrating in the top-bottom direction and a projection protruding upward from the circumference of the through-hole.

5. The condenser according to claim 1 , wherein the water receiving portion includes, in a sectional view substantially parallel to the pipe-supporting plates:

a plurality of corrugated portions, extending in a top-bottom direction and being bent in a corrugated form, which are disposed side by side in a left-right direction; and

branched portions that are provided near apexes of the corrugated portions and extend upward in a direction away from the corrugated portions.
