Cooling module and helmet having same

Abstract

A helmet includes a shell and a cooling module attached to the shell. The cooling module includes a heat pipe, a thermoelectric cooler, and a film type solar cell. The shell has an outer surface and an inner surface. The heat pipe is embedded in the shell and includes an evaporating section and a condensing section. The thermoelectric cooler includes a cold end brought into contact with the condensing section of the heat pipe, a hot end exposed to the exterior of the shell, and an array of N-type semiconductor elements and an P-type semiconductor elements electrically connected in serial sandwiched between the cold end and the hot end. The film type solar cell is provided on the outer surface of the shell and electrically connected with the thermoelectric cooler and used for supplying electric energy to the thermoelectric cooler. A cooling module is also included in the invention.
