HEATING RADIATOR-CONVECTOR AND ATTACHMENT METHOD OF REGISTER TUBE IN HOLE OF ITS TUBULAR HEADER Russian patent published in 2010 - IPC F24H3/08 F28F9/26 

FIELD: heating.

SUBSTANCE: inventions are intended for being used in heating equipment, and namely in heating radiators-convectors for water central heating systems and attachment methods of register tube in the hole of tubular header. Heating radiator-convector includes upper and lower tubular headers made of aluminium profile, connected with a number of vertical aluminium fin tubes of register by means of short tubular elements tightly sealed on one side by means of press fitting in register tubes, and on the other side - in holes of header by means of a sealing element located between the end of tubular element protruding to the header cavity and its inlet to header hole; at that, each tubular element is made in the form of a branch pipe having taper and cylindrical parts, on external surfaces of which there is at least one annular groove; at the point where cylindrical part is changed into taper one, there is a flange located between register tube edge and header, and sealing element is made in the form of inlet hole of an adapter sleeve pressed in the edge of inlet header hole and conjugated with annular flat surface of flange and cylindrical surface of branch pipe, the protruding end of which is flared by means of access on the side of taper part of branch pipe. Besides upper and lower headers at the attachment points of branch pipes have longitudinal flat sections the thickness of which is more than thickness of round walls, and finning of each aluminium register tube is made in the form of longitudinal radial plates located symmetrically relative to the tube axis, and front and rear planes of finning comprise at least with two plates adjacent to them the closed air channels interconnected with atmosphere at the level of upper and lower headers. Attachment method of register tube in the hole of tubular header of heating radiator-convector, which is implemented by means of intermediate element having taper surfaces with inverse taper by leading the end of intermediate element inside the header and its elastoplastic release; at that, intermediate element is made in the form of a branch pipe having taper and cylindrical parts; internal channel of branch pipe in the zone where its end is led into the header cavity is abruptly converging; plastic release is made by pushing the working puncheon via internal channel of branch pipe on the side of its taper part till the puncheon falls to the header cavity, and removal of working puncheon from the header cavity is performed by emptying.

EFFECT: inventions allow increasing strength of radiator-convector, simplifying manufacturing and assembly method thereof, increasing processibility and intensification of heat transfer.
