Abstract: Provided is a cooling device capable of appropriately cooling a cold insulator and keeping the cold insulator at an appropriate temperature. The cooling device includes a cooling portion that has an inner space storing an object, a measurement means of measuring a temperature corresponding to a temperature of the object stored in the inner space, and a control means of controlling a temperature of the inner space based on a measurement result by the measurement means, in which, based on the measurement result, the control means performs control to change the temperature of the inner space from a first setting temperature that is lower than a temperature at which the object in a liquid phase starts to be solidified to a second setting temperature that is higher than the first setting temperature and lower than a melting temperature of the object.

Abstract: It is an object of the present invention to provide a thermal energy storage member having sufficient dissipation capabilities and a storage container using the same, and a refrigerator using the same.

Abstract: The present invention is intended to provide a storage container that includes a shelf member holding a heat storage material arranged optimally. In a storage container that preserves an object at predetermined temperature, the storage container includes a storage room in which the object is preserved, and a shelf member disposed within the storage room, the shelf member including a flat portion on which the object is placed, and a heat storage material arranged to the flat portion in a way distributed depending on a temperature distribution near the flat portion within the storage room during steady operation. The heat storage material is arranged to be localized to a region of the flat portion at a relatively low-temperature side depending on the temperature distribution within the storage room.

Abstract: An object of the present invention is to provide a readily produced and easily handled heat storage member. The heat storage member 1 has a rectangular plane surface of, for example, 15 (cm)×20 (cm), and has a thickness of, for example, 10 to 15 mm. The heat storage member 1 includes a gelatinous latent heat storage material 12, and a large number of highly heat conductive fillers 14 dispersed in the latent heat storage material 12. The highly heat conductive fillers 14 are mixed in the latent heat storage material 12 with a bias in dispersion density. In the rectangular plane surface of the heat storage member 1, a periodic pattern is formed in combination of cellular (cell-like) regions 10, which are demarcated by, for example, hexagonal contour lines 16 and which are periodically arrayed in the vertical and horizontal directions.
