-
FIGS. 1 to 2 illustrate ahelmet 100 in accordance with a preferred embodiment. Thehelmet 100 is useful for athletes, drivers, workers, etc. Thehelmet 100 includes ashell 102, avisor 104 and acooling module 12. - The
shell 102 has afront side 1022, arear side 1024 and atop side 1026 corresponding to a wearer's face, rear side of head and top side of head, respectively. Thefront side 1022 of theshell 102 has aview window 1028, which exposes at least a portion of the wearer's face. Thevisor 104 is attached to theshell 102 by at least ascrew 106 and configured for protecting eyes and face from blowing. - The
cooling module 12 includes aheat pipe 122, athermoelectric cooler 124, aheat sink 126 and asolar cell 128. Theheat pipe 122 is embedded in theshell 102. Theheat pipe 122 has acondensing section 1224 which extends from thetop side 1026 to therear side 1024 and anevaporating section 1222 which connects with theevaporating section 1222 at thetop side 1026 and extends throughout theshell 102. Theheat pipe 122 can be selected from the group consisting of tube-type heat pipe, flat heat pipe etc. Theheat pipe 122 has a hollow cavity 1226 formed therein and a work fluid 1228 is filled with the hollow cavity 1226. The hollow cavity 1226 extends from the evaporatingsection 1222 to thecondensing section 1224. - The
thermoelectric cooler 124 includes acold end 1242, ahot end 1246 andthermoelectric elements 1244 sandwiched therebetween. Thecold end 1242 is brought into contact with thecondensing section 1224 of theheat pipe 122. In the preferred embodiment, thecondensing section 1224 is inserted in thecold end 1242. Theheat sink 126 is fixed on thehot end 1246 and exposed to an exterior of theshell 102. Theheat sink 126 is configured for dissipating heat emitted from thehot end 1246. Thesolar cell 128 has two electrodes (seeanode 1282 andcathode 1284 inFIG. 3 ) and the two electrodes are electrically connected with thethermoelectric cooler 124 by twoconductors 130, and thus form an electric current loop. Thesolar cell 128 is configured for supplying electric energy to thethermoelectric cooler 124. Thesolar cell 128 is a semiconductor device that can transform light into electric energy. In the preferred embodiment, thesolar cell 128 is a film type solar cell, for example Amorphous Si solar cell, poly-Si solar cell, CuInSe2 solar cell, GeCd solar cell and TiO2 solar cell etc. The film type solar cell is light and bendable so that thesolar cell 128 can be fixed on the outer surface of theshell 102 by adhesive or with a bolt. - Referring to
FIGS. 1 to 3 , thethermoelectric cooler 124 is a solid-state heat pump that operates on the Peltier effect. Thethermoelectric elements 1244 include an array of N-type semiconductors element 1248 and an array of P-type semiconductor elements 1250 electrically connected in series byelectric bars 132 and thermally connected in parallel. The array of N-type semiconductor elements 1248 and the array of P-type semiconductor elements 1250 are then affixed to thecold end 1242 and thehot end 1246. Thesolar cell 128 is electrically connected with the two ends of the array of N-type semiconductor elements 1248 and the array of P-type semiconductor elements 1250 in series. Thus, a series circuit is achieved between thesolar cell 128, the array of N-type semiconductor elements 1248 and the array of P-type semiconductor elements 1250. The array of N-type semiconductor elements 1248 and the array of P-type semiconductor elements 1250 form a thermocouple. The thermocouple can transfer heat from thecold end 1242 to thehot end 1246, so that heat emitted from thecondensing section 1224 of theheat pipe 122 that is inserted in thecold end 1242 can be dissipated in time. Generally, a material of thecold end 1242 and thehot end 1246 can be ceramics. - The
helmet 100 can emit heat produced by the wearer's body efficiently so that make the wearer feel comfortable based on thecooling module 12 including theheat pipe 122, thethermoelectric cooler 124 and theheat sink 126. Also, the electric energy that thethermoelectric cooler 124 needed is supplied by the film typesolar cell 128, which is cheap and environmentally friendly. - It is to be understood that any number of the
heat pipe 122 can be present (e.g., two, three etc). Also, when theheat pipe 122 can be a tube-type heat pipe or a plurality of tube-type heat pipes arranged side by side. The number of thethermoelectric cooler 124 and theheat sink 126 can be more than one, and still be within the scope of the preferred embodiment. - It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
