Abstract: A heat exchanger having a polyamine on at least part of a surface of the heat exchanger. The existence of polyamine on the surface of the heat exchanger allows the odor components to be temporality held by virtue of the action of polyamine, and the odor components are not released into an interior room or the like at once in conjunction with the evaporation of free water (such as condensed water). Thus, the release of odor components is made moderate, and changes in the concentration of odor components in the interior room are reduced, so that strong odors sensed by people are suppressed. A typical example of the polyamine is PEI, and a typical example of the heat exchanger is an evaporator used in a car air-conditioner.

Abstract: A cold storage heat exchanger includes a plurality of tubes, a coolant flowing in the tubes, a cold storage material container joined to the tubes, the cold storage material container defining a room that houses a cold storage material, and a distribution tank unit that distributes the coolant to the tubes. A coolant passage is formed in the tubes and the distribution tank unit. The distribution tank unit includes an aperture plate that reduces a passage cross-sectional area of the coolant passage. Among the plurality of tubes, the cold storage material container is joined to at least a tube disposed upstream in a coolant flow direction from the aperture plate in the coolant passage. Accordingly, cold storage performance may be improved.
