よい。Glycerin is a colorless, sweet-tasting (harmless to eat), viscous liquid that is soluble in water and hygroscopic. Glycerin has a specific gravity of 1.26, a melting point of 17.9°C, a boiling point of 290°C, and a specific heat of 0.540 at 0°C. Heat of fusion is 47.5 cal/
g, which is close to the maximum among organic compounds, and acts extremely advantageously as a cooling body. When this aqueous solution is frozen at about -10° C., it becomes a thin snow-like crystalline state and exhibits deformable flexibility. This flexibility increases as the concentration of glycerin increases and decreases as the concentration decreases. Therefore, the concentration of glycerin may be adjusted depending on the purpose of the cryocooler, and one with a relatively high concentration may be used if flexibility is required.

力性のある軟質発泡プラスチック製吸液体に、冷媒液を
残留空気を残して吸収させたものを防水容器に封入し、
冷凍すると共に、被冷却体と対向しない面を断熱体で覆
うことにより外部からの熱の浸入を遮断することを特徴
とする凍結冷媒液の長時間保存有効冷却法。 ２、連続気泡を含む弾力性のある軟質発泡プラスチック
製の吸液体に冷媒液を吸収させ、これらを防水容器中に
封入してなる凍結冷却体。[Scope of Claims] 1. A refrigerant liquid is absorbed into a flexible flexible foam plastic liquid absorbent molded into a shape suitable for cooling an object to be cooled, leaving residual air, and the liquid is placed in a waterproof container. Enclosed,
A method for effectively cooling a frozen refrigerant liquid for a long period of time, which is characterized by freezing and blocking the infiltration of heat from the outside by covering the surface that does not face the object to be cooled with a heat insulator. 2. A freezing cooling body made by absorbing a refrigerant liquid into a liquid-absorbing elastic plastic foam containing open cells and sealing the liquid in a waterproof container.
