Above-mentioned technical purpose of the present utility model is achieved by the following technical programs: novel temperature difference electricity generation device, comprise the thermo-electric generation unit, described thermo-electric generation unit comprises exhaust steam passage, thermo-electric generation lamella and heat dissipating layer, described exhaust steam passage arranged outside has heat dissipating layer, between described exhaust steam passage and described heat dissipating layer, the thermo-electric generation lamella is set, described exhaust steam passage comprises main exhaust and secondary blast pipe, and described secondary blast pipe has two and be evenly distributed on the described main exhaust outside at least.
As preferably, be provided with between described main exhaust and described secondary blast pipe waste gas is guided into the block plate of described main exhaust and described secondary blast pipe.
As preferably, the axle of described secondary blast pipe and the axle of described main exhaust in the same way, and the outer wall of described secondary blast pipe closely is connected with described thermo-electric generation sheet.
As preferably, rear and front end, described thermo-electric generation unit is respectively arranged with the taper aiutage in exhaust gas centralized in described main exhaust and described secondary blast pipe, the bottom surface of described taper aiutage is connected with described thermo-electric generation unit, and the upper bottom surface of described taper aiutage is identical with the cross section of described main exhaust.
As preferably, a plurality of fin of described heat dissipating layer arranged outside, described fin radially are the emission wire along described exhaust steam passage and evenly distribute.
As preferably, described fin described exhaust steam passage axially on curved setting, be the corrugated of rule.
As preferably, be provided with at least one reinforcement outside described heat dissipating layer, described reinforcement is connected with described a plurality of fin.
In sum, the utlity model has following beneficial effect: the contact area that increases blast pipe and waste gas, and make the temperature of blast pipe inside to rise faster, block plate can guide waste gas process in main exhaust and the secondary blast pipe, and secondary blast pipe is arranged on the main exhaust periphery uniformly; The radiation setting of the fin of heat dissipating layer, and fin is curved surface and can better the heat Quick diffusing be fallen; Because the exhaust gas inside pipe heats up than very fast, outside heat radiation is also than comparatively fast, so the thermo-electric generation sheet can form a larger temperature difference, because the front and back of secondary blast pipe are provided with the circulating rate that waste gas in secondary blast pipe suitably slows down in set section, can well increase waste gas and rest on time in secondary blast pipe.
