And.

Further, as shown in FIGS. 2 and 3, the cooling plate 10
A corrugated surface 11 having a wavy cross section for enhancing heat absorption (cooling) efficiency is formed on the upper surface of the device, and the surface 11 is exposed upward. The heat radiating plate 9 and the cooling plate 10 are both made of a metal having high thermal conductivity, and are formed of, for example, aluminum. Then, the head receiver 1 is placed on the cooling plate 10.

(Returning to FIGS. 1 and 2) A DC power plug 13 opening outward is attached to the side wall of the outer case 6. The plug 13 is electrically connected to a power supply device 14 for converting an alternating current such as a home power supply into a direct current having a predetermined voltage. The Peltier elements 3 and 3 are electrically connected to the plug 13. Here, the Peltier element 3 is an element made based on the Peltier effect in which heat is absorbed when two dissimilar metals are joined and current flows through the junction. It has a heat absorbing surface and a heat generating surface. In this cooling pillow, the Peltier element 3 has an upper surface as a heat absorbing surface and a lower surface as a heat generating surface.

Since the upper surface is an uneven surface 11, the surface area is increased and the heat absorption efficiency is increased. Therefore, the head receiving portion 1 can be efficiently cooled.

The lower surface of the Peltier element 3 generates heat, and the heat is transmitted to the radiator plate 9. Then, the radiator plate 9 is cooled by the cooling fan 7. That is, the cooling fan 7 rotates to allow the outside air to enter the exterior case 6 through the air inflow holes 12, and further pass through the air intake through hole 23 and the cooling fan 7 and between the tray-shaped member 22 and the radiator plate 9. Flows into. Then, the air deprives the heat radiating plate 9 of heat and is discharged to the outside from the heat radiating duct 15. Therefore, heat does not accumulate in the outer case 6, and the head receiving portion 1 can be kept at a stable low temperature.

[0015] As described above, according to the cooling pillow,
The human head can be cooled at a stable low temperature for a long time (while the current is flowing through the Peltier elements 3 and 3). In addition, since the head receiving portion 1 is provided on the cooling portion 2 so as to be able to be placed and removed, the head receiving portion 1 can be used upside down. In addition, the head receiving portion 1 can be removed for cleaning. Therefore, it is hygienic.

The ferromagnetic body 19 is made of a ferromagnetic substance having a Curie temperature near room temperature, and is formed of gadolinium, for example. The ferromagnetic material 19 undergoes spontaneous magnetization below the Curie temperature and becomes paramagnetic above the Curie temperature. Further, the ferromagnetic material 19 becomes ferromagnetic by generating heat when magnetized when it is paramagnetic, and thereafter becomes paramagnetic by absorbing heat when the magnetization is stopped.

The magnetizer 21 is configured to magnetize the ferromagnetic material 19 with a large magnetic flux density (for example, 6 to 7 Tesla). As such a magnetizer 21, for example,
Superconducting magnets. The upper surface of the magnetic cooler 20 is a heat absorbing surface, and the head receiving portion 1 is placed on the heat absorbing surface. Further, the magnetic cooler 20 has a heat radiating means (not shown) for releasing heat generated when the ferromagnetic material 19 is magnetized.

When the cooling pillow is turned on, the control means is operated, and the magnetizer 21 magnetizes the ferromagnetic material 19. The ferromagnet 19 generates heat due to the magnetization, and the heat is released to the outside by the heat radiating means. Thereafter, the magnetization is stopped. Thereby, the ferromagnetic material 19 absorbs heat, and the head receiving portion 1 placed on the upper surface of the magnetic cooler 20 is cooled. After the ferromagnetic material 19 becomes paramagnetic, the above-described ferromagnetic material
