ABSTRACT:
The present invention relates to the structure of a pipe plate unit for heat exchangers which may be employed in condensers, etc. that is used in thermoelectric and nuclear power plants. The object of this invention is to provide a structure for heat exchanger pipe plate units which reduces the number of construction steps and the labor costs for replacement of the pipe plate units, and which results in a pipe plate unit for heat exchangers after the replacement process that maintains a good seal for the fluids and which is adequately strong. The pipe plate unit for heat exchangers in which a plurality of heat conducting pipes are attached by welding at both ends to two opposing pipe plates, each bounded on one side by a fluid chamber, wherein the structure of the pipe plate unit for heat exchangers comprises a plurality of subassembly units to be assembled vertically and attached together, the plurality of subassembly units divide the pipe plate unit on the horizontal plane in a direction perpendicular to the surfaces of the pipe plates.
