Abstract:
1. A condenser comprising a condensing section that includes: a plurality of tubes, which are stacked one after another in a stacking direction, wherein each of the plurality of tubes forms a refrigerant passage therein to conduct refrigerant and is adapted to exchange heat between the refrigerant, which is in gas phase and is conducted through the refrigerant passage, and external fluid, which flows outside of the tube, to cause condensation of the refrigerant in the gas phase into the refrigerant in liquid phase in the tube at the condensing section; and a plurality of fins, each of which is placed in an inside of a corresponding one of the plurality of tubes to divide the refrigerant passage of the tube into a plurality of sub-passages, which are arranged one after another in a row in a row direction, wherein: at least a surface of each corresponding one of the plurality of fins placed in the tube is covered with a brazing material; each of the plurality of tubes and each corresponding one of the plurality of fins satisfy all of the following relationships: the brazing material, which covers at least the surface of each corresponding one of the plurality of fins placed in the tube, satisfies a relationship of 0.005≦S/L<0.5, where: an amount of the brazing material, which is present in each of the plurality of sub-passages, is set to form:
