    摘要： There is disclosed a rust prevention and hydrophilization treatment method for a flux-brazed aluminum-made heat exchanger which comprises subjecting the same to a rust prevention treatment by the use of a zirconium base compound and/or a titanium base compound, and thereafter subjecting the same to a hydrophilization treatment by means of a hydrophilization treatment agent composition containing the under-mentioned components: (1) 40 to 90% by mass of polyvinyl alcohol having a degree of saponification of at least 90%; (2) 3 to 40% by mass of polyoxyalkylene-modified polyvinyl alcohol in which 0.01 to 20% of pendant groups are polyoxyalkylene ether groups; (3) 1 to 30% by mass of an inorganic cross-linking agent which reacts with hydroxyl groups of the polyvinyl alcohol and modified polyvinyl alcohol; and (4) 1 to 20% by mass of a guanidine compound and/or a salt thereof. The above simplified method dispenses with a flux removal step without causing wastewater treatment problems, and thus assures favorable rust prevention and deodorization effects.

    摘要： A structural arrangement for an evaporator producing a uniform temperature gradient across its width. The structure is arranged so as to even out the flow of refrigerant within the evaporator. A first tank portion has a inlet and a second tank portion has a outlet. One end of each of plural tubes are connected thereto. A plurality of tubes allow refrigerant to flow from the first tank portion to the second. The tubes are arranged so as to provide equal flow distances for refrigerant across the evaporator, taking into account the directions of flow in the first and second tank portions. In a second embodiment, the inlet port and the outlet port are disposed at the first tank portion and the second tank portion respectively in such a manner that directions of the refrigerant flow within the first tank portion and the second tank portion are opposite to each other. In a third embodiment, one end of a first tube of the plurality is connected to the first tank portion closer to one end of the first tank portion, than where one end of a second tube is connected to the second tank portion closer to the other end of the second tank portion than the other end of the second tube. The inlet port is disposed close to one end of the first tank portion and the outlet port is disposed close to one end of the second tank portion.
