Heat exchanger for household refrigerator, has elongated strips arranged in form of grill on ducts so that contact between them are made at length side of rectangle resulting in transversal section of strips, where ducts canalize coolant

摘要

The heat exchanger has ducts (1) soldered to auxiliary units to perform heat exchange. The ducts have elongated strips (2) similar to wires in a transversal section in the shape of a flat rectangle, where ducts canalize a coolant. The strips are arranged in the shape of a grill on the ducts in a manner that the contact between the strip and the ducts is made at the length side (m) of the rectangle resulting from a transversal section (A) of the strips.
