METHOD OF PRODUCTION OF HEAT EXCHANGERS OUT OF POLYMERS Russian patent published in 2005 - IPC

FIELD: agriculture: heat engineering equipment for poultry and stock-rearing.

SUBSTANCE: the invention is dealt with the field of agricultural heat engineering equipment ensuring a heat transfer from one heat-exchanger to another in presence of aggressive corrosion-influencing components in one of them. The equipment may be used in the gas-air ventilation facilities of heat recovery in poultry and stock-rearing farms. The method of production of a cross-running heat exchanger out of a polymeric material containing a package made out of polymeric cellular plates bound to each other and encased in a box ensuring an inlet and an outlet of warm and cool air streams. At that the cellular plates located in one direction in a package are bound to each other by a two-sided polymeric adhesive tape through gaskets made out of the same polymer and placed along the surface and perpendicularly to directions of cells in a plate, are kept till full polymerization of the joints with following formation of the package on all its corners with metal angle sections into a rigid metal framework. At that in one of the vertical sides of the angle section they drill some bores ensuring a free running of a liquid. Then using a sliding fit the package is inserted in the guides made out of the angle sections and mounted perpendicularly to the corners of the air-distributive box so, that the bores of the lower corner of the package meet the bores of a lateral wall of a guide. The package is fixed in the guides formed by the metal angle sections. The bores of the lower angle section of a guide should be located opposite to the bores drilled-in in the lower wall of the air channel of the box placed above a draining container. The invention ensures the necessary tightness of the channels linking the heat exchangers, possibility to use the heat exchangers at low temperatures and also to increase the cost efficiency of the polymeric material cutting.

EFFECT: the invention ensures the necessary tightness of the channels linking the heat exchangers, possibility to use the heat exchangers at low temperatures and increased the cost efficiency of the polymeric material cutting.
