HEAT-EXCHANGER OF FLOOR HEATING CONVECTOR (OPTIONS) Russian patent published in 2008 - IPC F24H3/00 

FIELD: heating.

SUBSTANCE: heat exchanger consists of a pipe with straight and rounded sections, heat exchange plates fixed on adjoining straight sections of pipe, which form line of heating heat exchange elements together with straight sections of pipe. Connecting adjacent heating elements - middle rounded pipe sections connecting straight sections of pipe of the end heating element, rounded pipe section and supply and discharge sections of pipe bended to the middle of end part of exchanger are located at one end side of heat exchanger. Rounded pipe sections, connecting straight section of middle heat exchanging elements are situated on the other end side of heat exchanger. Heat exchanger rests on vertical supports. Supply and discharge sections of pipe are located at the outer side of one support. The second line of heating elements may be installed above the first line of heating elements and the second line pipe is connected with the first heating elements line. Adjacent straight pipe sections of adjacent heating elements are located from each other at a distance which is less than the distance between straight sections of each heating element of each line. Straight pipe sections of adjacent heating elements of lines may be located from each other at a distance which is less the distance between rounded sections of heating elements in each line. Intermediate line of heating elements may be installed between the first and second lines of heating elements; intermediate line pipe will be connected with first and second lines pipes. Straight sections of adjacent heating elements may be installed between each other at distance, which is less than the distance between straight sections of each heating element pipe in each line. At least, one additional intermediate line of heating elements may be installed in heat exchanger. Intermediate line pipe will be connected with the pipe of second heating element line and with pipe of additional intermediate heating elements line. Adjacent straight sections of heating elements situated in adjacent lines may be placed to each other at distance, which is less than the distance between straight pipe sections of each heating element in each line.

EFFECT: increase of heat exchanger efficiency.
