Abstract: A condenser has a core part having tubes, a first modulator tank and a second modulator tank. The first modulator tank is provided along a side portion of a header tank. The second modulator tank communicates with an interior of the first modulator tank and is provided along a lower edge of the core part in a gravity direction. An interior of the header tank is provided with a communicating space that communicates with the interior of the first modulator tank and an interior of the second modulator tank. The header tank has an introduction passage that guides liquid-phase refrigerant in the communicating space to a supercooling portion of the core part. A first connection part between the communicating space and the introduction passage is disposed on a lower side, in the gravity direction, of a second connection part between the communicating space and the second modulator tank.

Abstract: An object of the invention is to provide an effective cooling-energy storing performance and a stable cooling-energy radiating performance and to realize a high productivity. An evaporator has a plurality of refrigerant tubes arranged at almost equal intervals to form therebetween accommodating spaces. A plurality of cooling-storage containers are arranged in some of the accommodating spaces and fins are arranged in the remaining accommodating spaces. A cooling-storage unit is formed by one cooling-storage container and two refrigerant tubes arranged at both sides of the cooling-storage container. Each of the cooling-storage container has projections extending from one wall portion to the other wall portion to form heat exchange portions. The cooling-storage container is connected to the refrigerant tubes by soldering material.

Abstract: A cold storage heat exchanger includes multiple refrigerant tubes, a cold storage container, an inner fin, a cooling air passage and an air-side fin. The inner fin is arranged inside of the cold storage container. The cooling air passage, in which air flows to cool a space, is provided to contact a surface of the refrigerant tube on a side opposite to the cold storage container. The air-side fin is arranged in the cooling air passage and thermally connected to the refrigerant tube. The cold storage container includes multiple recess portions bonded to the inner fin, and multiple protrusion portions located on an outer side of the recess portions. The protrusion portions of the cold storage container are bonded to an outer surface of the refrigerant tube.

Abstract: An outer surface of a cold-storage container (or a refrigerant tube) is provided with a plurality of protrusion portions or recess portions. A cooling air passage, in which air flows to cool a space to be cooled in a cold storage time and in a cold release time of the cold storage material, is provided to contact a surface of the refrigerant tube on a side opposite to the cold storage container bonded to the refrigerant tube. The refrigerant tubes and the cold storage container form therebetween a cold-storage side air passage by the protrusion portions or the recess portions, such that air flows in the cold-storage side air passage separated from the cooling air passage. For example, the cold-storage side air passage is provided with a slanting space that causes condensed water or ice generated in the cold storage time to be drained along the cold-storage side air passage.

The cold storage container has a portion that stops and fixes the inner fin, and the cold storage container has a space where air is sealed. The space of the cold storage container is located at an upper side of the member that stops and fixes the inner fin. Accordingly, a stress applied to the cold storage container in the expansion of the cold storage material can be reduced.
