Description
Technical field
The present invention relates to the semiconductor thermoelectric technical field of power generation, the direct-fired thermoelectric semiconductor TRT of particularly a kind of high efficiency.
Background technology
Semiconductor mini thermoelectric heat body generator because its volume is little, easy to carry, simple to operate, only need have burning things which may cause a fire disaster provide heat just can the direct generation of electricity etc. characteristics, out of doors, remote districts and emergent etc. not have the power supply supply to be badly in need of again under the situation of electric power very popular.But; In order to practice thrift cost, be easy to carry, the electrothermal module that conventional semiconductor mini thermoelectric heat TRT uses is small-sized with respect to burning things which may cause a fire disaster usually; Directly thermoelectric generating device is placed the burning things which may cause a fire disaster top; The burning things which may cause a fire disaster heat that disperses can to around distribute, thermal-arrest is very difficult, causes the actual utilization ratio of heat low.Actual heat through electrothermal module reduces, and directly causes hot and cold the temperature difference of module to descend, and makes generating efficiency low.
CN101882899A discloses a kind of portable semiconductor thermal power generation device; The electrothermal module hot side that posts graphite paper in this device is close to the boss of step circle plate-like heat collector upper surface, and the electrothermal module huyashi-chuuka (cold chinese-style noodles) that posts graphite paper is close to the lower surface of band fan radiator, and the detachable buckle that is enclosed within on the radiator is buckled on the buckle base on the heat collector disk; With the firmly fastening of radiator, electrothermal module and heat collector; After directly over thermoelectric generating device places burning things which may cause a fire disaster, heat collector is with the heat transferred electrothermal module, and two faces of electrothermal module form the temperature difference; Promptly produce electric current, can supply power to portable electric appts.But the thermal-arrest mode of this structure, flame concentrate on the whole disc face, the burning things which may cause a fire disaster of dispersion can to around distribute, cause Btu utilization efficient low, thereby cause whole device generating efficiency low.
Therefore, it is little to invent a kind of used electrothermal module volume, but the collecting efficiency of device is high, and not only economy but also practical semiconductor mini thermoelectric heat device were effective solution.
Summary of the invention
The objective of the invention is; Small-sized with respect to burning things which may cause a fire disaster in order to overcome the employed electrothermal module of semiconductor mini thermoelectric heat TRT; Directly thermoelectric generating device is placed burning things which may cause a fire disaster top, the burning things which may cause a fire disaster heat of dispersion is difficult for concentrating, and causes that the electrothermal module hot-face temperature is unstable, the actual utilization ratio of heat is low; Cause hot and cold temperature difference deficiency to influence problems such as generating efficiency; Providing a kind of high efficiency direct-fired thermoelectric generating device, can be thermal source with the burning things which may cause a fire disaster, adopts the special heat collector that has collector mat and fin; So that the heat of efficient stable to be provided, utilize the radiator of a band fan to guarantee that hot and cold temperature difference of device improves power output and energy conversion efficiency simultaneously.
