HEAT-EXCHANGER Russian patent published in 2009 - IPC F28F27/02 

FIELD: heating.

SUBSTANCE: invention relates to heat exchange units and may be used in heat-exchangers with primary and secondary circuits containing valve for coolant flow control. For this purpose, the heat exchanger consisting of housing with primary circuit between inlet connection and return pipe connection, and the secondary circuit between feed line connection and drain connection, includes valve for coolant flow control through the primary circuit and actuator with the expanding element being affected by the secondary circuit temperature. The valve and expanding element are located from the opposite sides of heat transfer surface, wherethrough the heat from the primary side is transferred to the secondary side. So, the heat-exchanger is represented with plate heat-exchanger. If temperature in the secondary circuit is changed, the expanding element is extended or compressed. The expanding element is connected with the valve which controls coolant flow rate in the primary circuit.

EFFECT: development of compact heat exchanger.
