| 20130086938 | THERMAL STORAGE MATERIAL CONTAINER AND HEAT EXCHANGER - A cool storage material container is formed by brazing together peripheral edge portions of two aluminum plates. A cool storage material for storing cool is charged into a cool storage material accommodation space. The cool storage material container has a seal portion provided by closing a thermal storage material charging inlet which is formed at the peripheral edge portions of the two aluminum plates and is used to charge the cool storage material into the cool storage material accommodation space. The seal portion includes two outward protrusions which are formed by pressing and collapsing the thermal storage material charging inlet such that they project outward from the two aluminum plates and are brought into close contact with each other. The outward protrusions are bonded together by an anaerobic adhesive and are bent in the thickness direction of the aluminum plates such that their bent portions have a V-shaped cross section. | 04-11-2013 |
| 20130074340 | METHOD OF MANUFACTURING HEAT EXCHANGER - A method of manufacturing a heat exchanger includes forming elongated holes in two connection walls among a plurality of connection walls to be laminated, and forming paired notches on a claw forming portion of the remaining connection wall facing the elongated holes. A longitudinally intermediate portion of the claw forming portion is pressed toward the other end to break the claw forming portion at the longitudinal center and bend the claw forming portion at the notches to thereby form two claws forming pieces and form bent portions at the distal ends of the claws forming pieces. The claws forming pieces are bent at the notches to form claws. Distal end portions of the claws are bent outward to form fold-back portions, which are engaged with the outer surface of the connection wall at the other end, whereby all the connection walls are provisionally fixed together. | 03-28-2013 |
| 20130067946 | COOLING UNIT OF AIR CONDITIONING APPARATUS FOR VEHICLE - A cooling unit includes an evaporator with a cool storage function, and a drain case disposed below the evaporator. Cool storage material containers and outer fins of the evaporator have respective outward projecting portions which project from the refrigerant flow tubes toward the leeward side. The drain case includes a condensed water drain portion which drains condensed water generated on the evaporator from at least one of the lower end of the outward projecting portion of each cool storage material container and the lower end of the outward projecting portion of each outer fin. The cooling unit is preferably used in a refrigeration cycle which constitutes an air conditioning apparatus for a vehicle in which an engine serving as a drive source for a compressor is temporarily stopped when the vehicle is stopped. | 03-21-2013 |
| 20120305228 | CONDENSER - A condenser includes first and second header tanks provided at one end thereof such that the latter is located on the outer side of the former. First heat exchange tubes forming a first heat exchange path provided in a condensation part are connected to the first header tank. Second heat exchange tubes forming a second heat exchange path provided in a super-cooling part are connected to the second header tank. The first header tank has one communication section which communicates with the second header tank through a communication part and to which all the heat exchange tubes forming the first heat exchange path are connected. The communication part is provided at a height below the uppermost heat exchange tube among all the heat exchange tubes connected to the communication section. The upper end of the first header tank is located above the lower end of the second header tank. | 12-06-2012 |
