Claims (2)

Almost all of the styrofoam is wound on the outside of the propane cylinder, leaving all or part of it, and the gas is evacuated. If the inside of the cylinder is evacuated with a vacuum device, there is nothing inside. There is no room for heat to enter because only radiation is provided and this is further insulated by styrofoam. Since there is no heat medium in the propane cylinder, the temperature is kept low and the thermal equilibrium with the outside world is small in the propane cylinder, and the heat exchange with the polystyrene foam outside the cylinder is also small, A cooling source with a low temperature that can be kept for several weeks can be created, and the surrounding temperature can be reduced by several degrees. Put ice in the inside of the thermos bottle according to the same principle, tighten the lid tightly, and wind the outside of the thermos bottle almost entirely except for all or a part of the styrene foam to obtain a cooling source having the same effect as the above-mentioned propane cylinder. It is. A wide aluminum wheel is tightly wrapped around the outside of the propane cylinder, wrapped around the whole so as not to let air in, stop with cellophane tape or cover it tightly with transparent vinyl tape. If the inside of the cylinder is evacuated with the device, there is nothing inside, so the only way for external heat to enter is to radiate heat rays. Becomes very cold and becomes a cooling source.
Also, a wide aluminum wheel can be tightly secured outside the thermos bottle by the same principle, wrapped around the whole so as not to allow air to enter, stop with cellophane tape or cover it tightly with transparent vinyl tape, And a valve at the outlet, from which a vacuum is created in the bottle by means of a vacuum device, providing a cooling source with the same effect as a propane cylinder, according to the same principle as a cylinder. In addition, both the cylinder and the thermos may be painted with mirror finish instead of aluminum wheels. 2. The cooling source according to claim 1, wherein the heat rays are reflected by the aluminum wheel.
