The present invention provides a heat exchanger, an air conditioning apparatus, and a method for manufacturing the heat exchanger capable of reducing the scattering of condensate water from curved portions to the downstream side in the direction of airflow. An indoor heat exchanger includes lower fins and upper fins. The upper fins are inclined in the direction of the airflow at an angle formed between the longitudinal axis of the upper fins and the vertical direction, the range of the angle being equal to or greater than the range of an angle formed between the longitudinal axis of the lower fins and the vertical direction, and the upper fins are disposed adjacent to top ends of the lower fins. The upper fins have curved portions that are curved in proximity to the portions bordering the top ends of the lower fins on the downstream side in the airflow direction F.

Heat exchanger, air conditioning apparatus, and method for manufacturing heat exchanger

Hydrogen-rich reformed gas is produced by reaction including partial oxidation of feed gas in a reforming reaction section ( ). In this case, for the purpose of reducing temperature variations in the reforming reaction section ( ), improving the thermal efficiency thereof and providing a reformer (A) with a simple and compact construction, the reformer (A) is formed in a double-wall structure consisting of a housing ( ) and partitions ( ), ( ) inside of the housing ( ), the reforming reaction section ( ) is contained between the partitions ( ), ( ), and a feed gas passage ( ) is provided by the space between the housing ( ) and the partition ( ). In this manner, the feed gas passage ( ) is provided in the surrounding area of the reforming reaction section ( ). The reforming reaction section ( ) is thermally insulated by the feed gas passage ( ) so that temperature variations in the reforming reaction section ( ) can be reduced. The feed gas in the feed gas passage ( ) is preheated by heat of reaction in the reforming reaction section ( ) so that the self-recovery of heat can improve thermal efficiency of the reformer (A). In addition, a preheater for preheating the feed gas can be formed integrally between the feed gas passage ( ) and the reforming reaction section ( ) thereby compacting the construction of the reformer.
