Panel-type counter-flow heat exchanger with fin structures formed from sheet metal

摘要: A heat exchanger capable of use as a counter-flow comprises series conduits for first fluid, the being arranged in panels that are spaced apart. The intervening spaces traversed by second and surface-extending elements located such spaces, each element comprising sheet from which portions have been pressed out to define number knuckles heat-transmitting contact with conduit panel on one side space. At least some may be secured panel.
