The Unknown Semiconductor
It sits on the surface of a wood stove. When the stove heats up, a d.c.
fan blows hot air around your house. The temperature difference between the base and the heat sink and fan on the top generates enough current to power the d.c. fan. It is called an EcoFan and is made in Canada. Every time the unit is dropped, the glass like PN semiconductor device goes NFG. (Like breaking a piece of glass) The manufacturer wants $48.00 plus tax and shipping to fix a unit. This is a bit much when a new unit costs about $100.00. THEY WILL NOT SELL A SEMICONDUCTOR SEPARATE NOR WILL THEY PROVIDE A PART NUMBER. I suspect it is some kind of house unit manufactured in the Orient. It has no part number on it. This is a very Canadian way of running a business. Anyone know where to get a replacement part? I believe the device could be called a PN Thermoeletric Generator. VA3JQ |
