HEAT EXCHANGER AND DISPLACER USED IN IT Russian patent published in 2014 - IPC F28D7/00 

FIELD: heating.

SUBSTANCE: heat exchanger has vertical heat exchange tubes for the passage of a cooling heat carrier spreading along the whole heat exchange cavity. The heat exchange tubes are combined into separate groups of tubes and the separate groups of tubes are separated from each other by vertical channels. In a central zone of the heat exchange cavity there is a vertical header channel free from the heat exchange tubes. Each group of tubes is arranged in a separate zone of the housing, which has a shape of a circle sector in a cross section, which is spread from the wall of the cylindrical housing to its central zone. The heat exchanger has a displacer made in the form of a solid body containing a vertical rod and vertical radial partition walls connected to it. The displacer rod is located in the central channel, and each partition wall is located in the appropriate vertical channel dividing two adjacent groups of the heat exchange tubes.

EFFECT: equalisation of a heat load of the heat exchange tubes by redistribution of flows of a liquid-metal heating heat carrier in an inlet chamber, and reduction of vibration loads.
