Abstract There is disclosed herein an improved multipass condenser construction having provisions therein which allow the condensate formed from each pass through the core portion thereof to by-pass substantially all of the remaining core portions thereby promoting maximum efficiency of the condenser. The condenser comprises a pair of vertically extending headers each having a plurality of baffles provided therein and an interconnecting core structure. The baffles are arranged so as to cause a gaseous fluid to flow through the core structure in alternating directions so as to be cooled and condensed to a liquid state. Each of the baffles is provided with a small aperture which allows condensate formed from each pass of the gaseous fluid through the core structure to by-pass the remaining portions of the core and flow directly to the lower end of the headers. Also, in that the volume of fluid to be passed through the core structure is constantly being reduced due to the separation of the condensate and the cooling of the gaseous fluid, successively fewer fluid conducting members are provided for successive flow paths while still maintaining the same overall flow capacity for the condenser unit.
A condenser comprising: a plurality of vertically disposed fin members each having a plurality of integral horizontal tubular projections, said fin members being arranged in a stacked substantially coplanar spaced relationship with said tubular projections being arranged in a telescopic nested relationship so as to define elongated fluid conducting conduit members; a first elongated tubular member extending generally perpendicular to said fluid conducting conduit members and having an interior connected in fluid communication with said conduit members; a plurality of baffle members secured within said tubular member in a parallel spaced apart relationship to define a series of chambers within said tubular member, said baffle members being spaced so as to have a first predetermined number of conduit members opening into a first chamber defined by a first and second baffle member and a second number of said conduit members opening into a second chamber defined by said second and a third baffle, said first predetermined number of fluid conduits comprising an inlet group for conducting fluid into said first chamber and an outlet group for conducting fluid out of said first chamber, said inlet group having a greater number of said fluid conduits than said outlet group; and each of said baffle members having a bore allowing direct communication between adjacent chambers, said bore being adapted to allow condensed fluid to pass therethrough and being further adapted to prevent passage of uncondensed fluid therethrough.
