Head cooling unit

Abstract

The neck cooling device 1 of this product is composed of two overlapping sheets 2 and 3. In the reference front view showing the welded portion, the yellow portion is the welded portion 4, and as shown in the reference cross-sectional view, the portion other than the welded portion 4 is a hollow portion 5. As shown in the reference front view showing the connected tubes, one end of the water supply tube 7 is connected to one tube connection portion 6, and one end of the water discharge tube 9 is connected to the other tube connection portion 8. The neck cooling device 1 is inserted through the insertion opening 11 shown in the reference front view showing the neck cover, and the neck cooling device 1 is attached to the neck cover 10 as shown in the reference front view showing the attached state to the neck cover. An elastically deformable curved shape-retaining plate is inserted through the insertion opening 11. Furthermore, the other ends of the water supply tube 7 and the water discharge tube 9 are each connected to a water cooling portion. The neck cover 10 is attached to the neck as shown in the reference oblique view showing the usage state. The neck cover 10 can be stably attached to the neck by the elastic force of the curved shape-retaining plate. Then, the water cooled in the water cooling section is sent by a pump from the water supply tube 7 to the cavity 5, and the water that passes through the cavity 5 is discharged from the water discharge tube 9, sent to the water cooling section where it is cooled again, and then sent to the cavity 5 via the water supply tube 7. In this way, the cooled water circulates inside the neck cooling device 1, cooling the neck.
