1. A condenser, comprising:
a fan;
a fluid inlet in an upper manifold, wherein the fluid inlet is configured to render fluid entering;
a fluid outlet in a lower manifold, wherein the fluid outlet is configured to render fluid exiting;
a plurality of multiport tubes extending between the upper and lower manifold, wherein the multiport tubes are provided with a plurality of separate flow channels which are delimited by outer opposite side walls and internal intermediate walls extending between the outer opposite side walls of the tubes, the multiport tubes providing a flow path between the upper manifold and the lower manifold, wherein the multiport tubes define a channel space between the multiport tubes;
a plurality of cooling plates extending between the upper manifold and the lower manifold, wherein the cooling plates are in thermal contact with the multiport tubes to receive a heat load from fluid in the flow channels;
the cooling plates having outer edges which protrude out from the channel space and are directed away from the channel space;
the outer edges of the cooling plates extending outwardly beyond a periphery of a space defined between the upper manifold and the lower manifold;
the condenser having a perpendicular configuration with the plurality of cooling plates that have side surfaces which are perpendicular to the outer opposite side walls of the multiport tubes;
first ones of the plurality of cooling plates having their outer edges protruding out from the channel space in a first direction having a first inner edge attached to a first base attached to and extending along first outer side walls of the multiport tubes by brazing;
second ones of the plurality of cooling plates having their outer edges protruding out from the channel space in a second direction having a second inner edge attached to a second base attached to and extending along second outer side walls of the multiport tubes by brazing;
the first ones of the plurality of cooling plates and the second ones of the plurality of cooling plates being attached to each other via being attached to the multiport tubes by brazing without using any other fasteners to connect the first ones of the plurality of cooling plates and the second ones of the plurality of cooling plates;
each of the plurality of multiport tubes being sandwiched between the first ones of the plurality of cooling plates and the second ones of the plurality of cooling plates with a corresponding outermost multiport tube among the multiport tubes being exposed by a corresponding slit formed between a corresponding outermost cooling plate among the first ones of the plurality of cooling plates and a corresponding outermost cooling plate among the second ones of the plurality of cooling plates and extending between the upper manifold and the lower manifold; and
the fan being configured to generate a fan assisting airflow between the cooling plates along the flow path in a direction from the fluid outlet towards the fluid inlet.
