摘要:
An analysis supporting apparatus that supports a product analyzing operation, includes a model-data generating unit that generates model data regarding an analysis model of an analysis target component in association with component hierarchy data representing a hierarchy of components forming an analysis target product; a model-data updating unit that reflects results of an analyzing process in the model data; and a simplified-model generating unit that generates, based on a rule registered in advance, simplified model data from the model data in which the results of the analyzing process have been reflected by the model-data updating unit.

In a cooling structure for cooling circuit element modules that are mounted on a circuit board and has heat sinks, there are provided a main duct to which the circuit element modules are connected, and a coolant supplying device which is connected to the main duct and supplies a coolant to the main duct.

A support member is designed to move in the longitudinal direction in a rack mount type disk array apparatus. A frame member is attached to the support member for relative rotation around the rotation axis located between the front and rear ends of the frame member in the longitudinal direction. Recording disk drives are held within the frame member in an upright attitude. The recording disk drives can be removed from and inserted into the frame member in a facilitated manner. This leads to a facilitated replacement of the recording disk drives. Moreover, the upper face of the frame member is allowed to face forward through the rotation around the rotation axis. Even if the disk array apparatus is placed at a higher level, the operator easily accesses the recording disk drives in the frame member.

In an electronic device that contains a cooling system in which the refrigerant circulates through both the base and the heat-radiator and the heat-radiator is installed away from and to the side of the heat-generator, the heat-generator is positioned on top of the base. This means that the height of the base in the electronic device becomes relatively low, and so the height of the heat-radiator—which must be installed above the height of the base—can be increased, meaning that the required heat-radiating region can be secured and high-performance cooling becomes possible.

An electronic apparatus includes a circuit board, a connector provided on the circuit board, an integrated circuit module attached to the connector, and a heat sink attached to the integrated circuit module. A heat transfer device is disposed at a position separate from the heat sink and arranged in a cooling air passageway. A heat conduction path thermally connects the heat sink with the heat transfer device. Since the heat transfer device can be arranged outside the frame of the apparatus, the heat transfer device can be constructed to have a sufficient cooling capacity, while the integrated circuit module and the heat sink can be constructed in a relatively compact design.
摘要:
A refrigeration system allows the refrigerant to circulate through a closed circulation channel. A dry evaporator is incorporated in the circulation channel. The dry evaporator is designed to keep a quality smaller than 1.0 in evaporating the refrigerant. The quantity of heat transfer per unit area, namely, a heat transfer coefficient depends on the quality. The heat transfer coefficient remarkably drops when the quality of the refrigerant exceeds a predetermined threshold level before the quality actually reaches 1.0. The quality of the refrigerant kept below the predetermined threshold level during vaporization of the refrigetant in the dry evaporator allows a reliable establishment of a higher performance of cooling. On the other hand, if a refrigerant completely evaporates in a dry evaporator in a conventional manner, the heat transfer coefficient of the refrigerant remarkably drops after the quality of the refrigerant exceeds the predetermined threshold level. Accordingly, the conventional dry evaporator is forced to absorb heat at a lower heat transfer coefficient, as compared with the present dry evaporator.
