Abstract: A refrigerant heat exchanger has the passage defining member. The passage defining member is made of carbon fiber reinforced plastics. The passage defining member has a tube portion defining a refrigerant passage. The passage defining member has the plate portion which spreads from the tube portion. In the tube portion, carbon fibers are oriented to surround the tube portion. This orientation contributes to a pressure resisting performance in a radial direction of the tube portion. In the plate portion, the carbon fibers are oriented to protrude from the tube portion. This orientation contributes to improve mechanical strength in the plate portion. The carbon fibers are extended over both the tube portion and the plate portion. This orientation promotes thermal transfer over the tube portion and the plate portion.

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.
