METHOD OF FIXING PLATES TO HEAT EXCHANGER PIPE Russian patent published in 2009 - IPC F28F1/00 

FIELD: heating.

SUBSTANCE: invention relates to heat engineering, namely to manufacturing procedures of connecting a heat exchanger pipe to many pipe ribbing plates or, for example, to one spiral plate made of a strip and having an axially directed opening for the pipe to enter the spiral, and is aimed mainly at using in the series-produced convectors for heating building rooms in the construction. It can also be used in other industry branches. The method of fixing plates to the heat exchanger pipes involves inserting the pipes into the plates' openings and increasing the pipe diametre up to the rigid fixation of the plates on the pipe, the pipe diametre is increased by sealing of its cavity, introducing working substance into the pipe cavity and increasing the working substance pressure up to the rigid fixation of the plates on the pipe. Air or liquid or explosive material or flammable explosive gas can be used as the working substance.

EFFECT: reducing power and labour demand for the connection of the pipe with the heat exchanger plates and improving the heat exchanger functionality.
