HEAT EXCHANGER Russian patent published in 2007 - IPC F28D15/02 

FIELD: power engineering.

SUBSTANCE: heat exchanger comprises housing that receives a bank of pipes arranged in horizontal rows. The pipes are mounted with a spaced relation one with respect to the other to form slot passages and are perpendicular to the direction of flow of heat-transfer fluids. The section of evaporation of heat pipes are mounted inside the housing to define common evaporation zone. The sections of condensation of the pipes are arranged outside of the housing. The heat pipes of the common evaporation zone are mutually perpendicular and arranged in rows in staggered order and are secured to the adjacent walls of the housing. The module is additionally provided with the same housing receiving identical pipe bank and common evaporation zone. Each row of the heat pipes of the additional housing is interposed between the rows of heat pipes of the main housing to define common condensation zones in the common housing of the module. The common evaporation zones and common condensation zones are positioned in the mutually perpendicular planes along the diagonals of the common housing of the module to define separated passages for flowing heat-transfer fluids.

EFFECT: enhanced efficiency of heat exchange.
