A method for surface treating a heat exchanger and an aluminum heat exchanger obtained from this method are provided that can effectively suppress the foul odor characteristic to flux that emanates following degradation of a hydrophilic coating film and a chemical conversion coating film in a non-corrosive flux brazed heat exchanger on which flux easily remains. The method for surface treating a non-corrosive flux brazed heat exchanger made of an aluminum material conducts a pickling treatment step, a chemical conversion treatment step, and a deodorizing treatment step on the heat exchanger, in which the acidic cleaning agent contains nitric acid and sulfuric acid as well as a predetermined amount of ferric salt, and the surface treatment agent contains silica grains coated by a vinyl alcohol polymer and polyallylamine resin such that the total content of the silica grains and the vinyl alcohol polymer is a predetermined amount.

A concave design forming unit with the desired form is formed on the surface of a molded component for use in injection molding using a low melting point metal material. An injecting molding cavity of the predetermined shape is formed from a metal mold, and after mold curing the molten metal, the molded goods are removed from the injection molding cavity. The injection molding cavity is formed by a first metal mold unit and a second metal mold unit, the metal mold having a trapezoidal concave design forming unit with the predetermined height formed on the metal mold inside surface of the first metal mold unit or the second metal mold unit forming said injection molding cavity. The metal mold is heated to a predetermined metal mold temperature, and the molten metal heated to the predetermined molten temperature will be injected into the injection molding cavity of the heated metal mold at the predetermined injection rate. After the injected molten metal injected it is chilled and solidified, the first metal mold unit and the second metal mold unit are separated and the molded component removed from the injection molding cavity.

Disclosed is a heat exchanger that can more efficiently transfer heat between a heat-exchange fluid and an object with which heat is to be exchanged. A heat exchanger (1) can transfer heat between a heat-exchange fluid flowing through flow paths (R1) and a fluid with which heat is to be exchanged flowing through other flow paths (R2) by means of the flow path structure member (10) (a first metal sheet (11) and a second metal sheet (12)) in which the flow paths (R1 and R2) are formed. The flow paths (R1 and R2) are formed so that the side surfaces thereof are not straight and so that the depths thereof change along the flow direction.
