In the configuration of the present invention, the portion that absorbs heat is set inside the latent heat storage material in the supercooled liquid state, and a voltage is applied to locally cool the latent heat storage material. As a result, at the same time when the latent heat storage material starts to solidify, the latent heat of the heat storage material is released and heat is transferred from the heat storage material to the target liquid, for example, cooling water. Since the heat transfer due to this latent heat occurs rapidly, the temperature of the cooling water rises rapidly.

As a result, latent heat is released in synchronization with the start of solidification of the latent heat storage material, causing heat transfer from the heat storage material to the target liquid. Since the heat transfer due to this latent heat occurs rapidly, the temperature of the heat medium rises rapidly. Therefore, for example, warm-up of the vehicle in the cold driving state can be promptly promoted.

さらに向上すことができる。In a preferred embodiment, the heat generating side of the thermoelectric element is arranged in the heat medium that receives heat from the heat storage material. For this reason, the temperature generated in the heat generating portion is taken by the low-temperature target liquid, and thus plays a role of assisting the operation of the thermoelectric element, and the reliability of the operation of the nucleating device can be improved. Also, when the enclosure member is provided, the heat storage material first
Further cooling by the thermoelectric element causes a phase change.
This phase change propagates to the outside of the enclosure through the communication hole that communicates the inside and outside of the enclosure member, and the phase change rapidly propagates throughout the heat storage material to release latent heat. In this case, since the heat storage material inside the enclosure member is intensively cooled, the cooling by the thermoelectric element can be effectively caused and the phase change can be surely caused. That is, the reliability of the nucleus producing apparatus 1 can be further improved.
