It is well known that heat storage materials are used to utilize latent heat. For example, when using dimethyl adipate (M.P8℃) as a heat storage material and freezing it to cool water at 30℃,
The dimethyl adipate usually does not freeze at 8°C, but freezes at lower temperatures, making it impossible to maintain the specified temperature when cooling the water.
It was easy to cause a supercooling phenomenon where it was cooled to ~6°C. In order to prevent this supercooling phenomenon, it is possible to coexist with different types of substances that act as crystal grains in the heat storage temperature range, such as fine powders that exhibit a suspended state in the heat storage material, such as barium-based hydroxide, borax, or by stirring or vibration. It performs mechanical actions such as

However, it has been extremely difficult to allow different substances to coexist, as it is necessary to use a material that has approximately the same specific gravity as the heat storage material and that does not show any reaction with the heat storage material. In addition, when mechanical means are used, the equipment must be large in scale and expensive.

The present invention was developed as a result of extensive research in view of the current situation and the discovery of a heat storage pipe that can prevent overcooling with extremely simple operation. That is, the present invention is characterized in that, in a heat storage pipe formed by filling the pipe with a latent heat storage material, a large number of metal linear bodies are inserted into the heat storage material.

In the present invention, the linear body may be any bundle of metal round wires, mesh, steel wool, etc. In short, there are 500 to 1000 metal wires such as copper wire, steel wire, iron wire, and aluminum wire inside the heat storage material. It suffices if a large number of them are installed. Moreover, the thickness is usually 0.1 mm to 0.5 mm. The reason is
If it is less than 0.1mm, it may be easily cut.
Moreover, if it exceeds 0.5 mm, the amount of heat storage material in the pipe will decrease and latent heat will not be fully utilized.

Further, as the metal wire, it is particularly preferable to use a wire that is partially flattened rather than a round wire, or a wire whose surface is etched to provide uneven portions. The reason for this is that freezing nuclei are generated on the surface of the wire, which promotes the supercooling prevention effect.

又蓄熱材としては潜熱が大きなものが望ましく

The heat storage material preferably has a large latent heat and is selected depending on the specified cooling temperature. For example, if you want to keep the liquid to be cooled at 7-8℃, use dimethyl adipate (M.P 8℃, 40kcal)
If you want to maintain the temperature at 27-28℃, methyl stearate (M.P 28℃, 40kcal) is used.

Also, the pipe is not particularly limited,
