HEAT EXCHANGER FOR REFRIGERATOR AND METHOD FOR FABRICATING SAME Russian patent published in 2008 - IPC F25B39/00 F28F3/12 

FIELD: heating, refrigeration art.

SUBSTANCE: invention refers to a heat exchanger such as an evaporator, a condenser for a refrigerator, as well as to a method for fabricating the same. Said heat exchanger for refrigerators comprises a board and a refrigerant-carrying tubing that is in thermally conductive contact with said board and with a retaining material layer being attached to said tubing. The retaining material layer consists of a bitumen compound and it is bonded to the board by an adhesive layer. The tubing has a flattened cross-section. The adhesive layer consists of a heat-activated adhesive. The bitumen compound contains from 50% to 80% of a filler. Stone powder is used as said filler. A coat of varnish is applied to the retaining material layer face that is opposite the board. An average thickness of the retaining material layer is of 0.5 to 2 mm, and preferably of 1.0 to 1.5 mm. The method for fabricating such a heat exchanger, in particular its evaporator or condenser, includes the following steps: forming a package comprising board, refrigerant-carrying tubing and plate of bitumen compound, heating said plate and pressing said package together. The board, tubing and bitumen compound plate are laid up in the above said order.

EFFECT: providing an inexpensive heat exchanger with improved performance.
