20110258406 | STORAGE APPARATUS AND CONTROL METHOD OF STORAGE APPARATUS - A storage apparatus having a plurality of logical volumes, each providing a data storage area to an external device, comprises a storage device providing a physical storage area, and a storage controller creating a plurality of unit physical storage areas from the storage device, operating each of the logical volumes as a virtual volume in which, in response to a data TO request from the external device, the unit physical storage area is added to each of the logical volumes, selecting any one of the logical volumes as a primary volume, selecting any one of the rest of the logical volumes as a secondary volume, the primary volume and the secondary volume being configured as a copy pair in which data in the primary volume can be copied to the secondary volume, in the case that the primary volume receives a discarding request for the unit physical storage area from the external device, determining whether or not the unit physical storage are exists, the unit physical storage area configuring the secondary volume corresponding to the unit physical storage area being a target of the discarding request, and in the case that it is determined that the unit physical storage area configuring the secondary volume exists, transmitting to the secondary volume an instruction for discarding the unit physical storage area assigned to the secondary volume. | 10-20-2011 |
20140317367 | STORAGE APPARATUS AND DATA COPY CONTROL METHOD - A storage apparatus comprises a storage controller and multiple storage devices. The storage controller sends, to either a storage device which is a copy source of copy-target data, or a storage device which is a copy destination of the copy-target data, a copy indication showing areas of the copy source and the copy destination, and the storage device, which receives the copy indication, copies data of the copy-source area to the copy-destination area based on the copy indication without going through the storage controller. | 10-23-2014 |

20090146415 | Pipe-joint structure for heat exchanger - A pipe-joint structure according to the present invention is advantageously used in an air-conditioner system mounted on an automotive vehicle. A compressor including an expansion valve is connected to an evaporator through the pipe-joint structure. The pipe-joint structure includes an inserting portion of a pipe connected to the compressor and a socket connected to the evaporator. The inserting portion is inserted into a hole formed in the socket. A front end of the inserting portion is positioned not to extend into an enlarged portion of the socket to thereby avoid formation of a dead-end small space between the inserting portion of the pipe and the enlarged portion of the socket. Refrigerant entering the socket from the evaporator smoothly flows without stagnation, and thereby noises caused by the refrigerant flow are suppressed. | 06-11-2009 |
20100065244 | Cool-storage type heat exchanger - 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. | 03-18-2010 |
20100307180 | Cold-storage heat exchanger - 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. | 12-09-2010 |
20120285668 | COOLING-STORAGE TYPE HEAT EXCHANGER - Multiple cooling-storage containers are arranged in respective spaces formed between neighboring refrigerant tubes. The cooling-storage container is made of a pair of outer envelope portions, each forming a side wall. Multiple convex portions and concave portions are formed in the side walls so that air passages are formed between refrigerant tubes and the concave portions. A sectional area of the air passage formed in a lower portion of the cooling-storage container below a predetermined height is made larger than that of the air passage formed in an upper portion of the cooling-storage container above the predetermined height. | 11-15-2012 |
20140083662 | Cold-Storage Heat Exchanger - A cold storage heat exchanger includes multiple refrigerant tubes, a cold storage container that is bonded to the refrigerant tube and defines a compartment receiving a cold storage material, and an inner fin arranged inside of the cold storage container. 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. | 03-27-2014 |
20140083663 | Cold-Storage Heat Exchanger - 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. | 03-27-2014 |
20140090826 | Cold-Storage Heat Exchanger - A cold storage heat exchanger includes multiple refrigerant tubes having therein refrigerant passages. The refrigerant tubes are arranged to provide a clearance therebetween. The cold storage heat exchanger further includes a cold storage container that is brazed with the refrigerant tube and defines a compartment receiving a cold storage material. The cold storage container has an open-hole portion at a brazed part with the refrigerant tube. Accordingly, efficiency of heat exchange by the cold storage heat exchanger can be improved. | 04-03-2014 |
20150068718 | EVAPORATOR - An evaporator is provided with a refrigerant pipe, a cold storage case which has inner fins mounted therein, and air-side fins. The evaporator is characterized in that the cold storage case is provided with: a filling opening for filling the cold storage case with a cold storage material; a first flow passage connecting to the filling opening and extending in the same direction as the direction of inflow of the cold storage material; and a second flow passage connecting to the first flow passage and extending in the direction intersecting the first flow passage. | 03-12-2015 |
