    摘要： An object is to provide a two-stage expansion refrigerating device capable of performing control with low cost so that a pressure of a refrigerant which has flowed through a high-pressure-side expansion unit is an optimum pressure, the device comprises a control unit (a controller) which controls a compressor (a low-stage-side compression element and a high-stage-side compression element) and each expansion unit (a high-pressure-side expansion valve as a high-pressure-side expansion unit and a low-pressure-side expansion valve as a low-pressure-side expansion unit), and a temperature sensor (a temperature detection unit) which detects a temperature of the refrigerant which has flowed through the high-pressure-side expansion valve, and the controller estimates a pressure of the refrigerant which has flowed through the high-pressure-side expansion valve based on a temperature detected by the temperature sensor, and controls one of the high-pressure-side expansion valve and the low-pressure-side expansion valve based on the estimated pressure.

    摘要： A thermal diffuser includes a plurality of thermally-conductive plates, each of which has a strip-like shape. The plurality of thermally-conductive plates is laminated onto one another in a plate-thickness direction of the strip-like shape to form a laminated body. Each of the plurality of thermally-conductive plates has thermal conductivities in a longitudinal direction and in a width direction of the strip-like shape better than a thermal conductivity in the plate-thickness direction. The thermally-conductive plates has sides, each of which extends in the longitudinal direction. The laminated body is formed such that the sides of the thermally-conductive plates form a plate surface of the laminated body, which surface extends in the plate-thickness direction that serves as a lamination direction, in which the thermally-conductive plates of the laminated body are laminated. A direction perpendicular to the plate surface corresponds to a thickness direction of the laminated body.
