a thermoelectric fan

Abstract

The invention discloses a heat electric fan which comprises a flow guiding outer shell with an opening at the upper end. The bottom of the flow guiding outer shell is fixedly provided with a mounting base. A motor which is used for driving a vane to rotate is arranged on the mounting base. A counter bore is formed in the lower end face of the flow guiding outer shell. A thermoelectricity module is arranged in the counter bore. A hot end heat transfer plate which presses the thermoelectricity module tight is arranged at the opening of the counter bore. When the heat electric fan is used in cooperation with a heating stove, by arranging the thermoelectricity module and adopting the thermoelectric conversion technology, heat of a heating furnace is used for electricity generation, accordingly, the fan operates, upper-lower-layer cold-hot air in a camping tent in a heating state is subject to full convective mixing, accordingly, the air temperature gradient in the tent is lowered, the living comfort degree during heating of the tent is improved, the problem of insufficient effective heat is solved, and important effect on improving outdoor camping heating guaranteeing capacity in winter is achieved.

Description

technical field [0001] The invention belongs to the technical field of thermoelectric power generation, and in particular relates to a thermoelectric fan. Background technique [0002] At present, when camping in the wild in winter, stoves are generally used for heating inside tents, and stoves mainly rely on radiation and natural convection to release heat. The air temperature in the area is low; the air temperature on the top of the tent is high, and the air temperature near the ground is low, that is to say, the temperature gradient in each area inside the tent is relatively large. Taking a tent with a size of 5m×6m as an example, the stove is located in the center At this time, the measured value of the temperature difference inside the tent can reach up to 30°C, and the living comfort is very poor. In addition, the natural convection of the hot air is at the top of the tent, and the cold air is near the ground. It actually feels like the head is hot and the feet are co...

Problems solved by technology

[0002] At present, when camping in the wild in winter, stoves are generally used for heating inside tents, and stoves mainly rely on radiation and natural convection to release heat. The air temperature in the area is low; the air temperature on the top of the tent is high, and the air temperature near the ground is low, that is to say, the temperature gradient in each area inside the tent is relatively large. Taking a tent with a size of 5m×6m as an example, the stove is located in the center , the measured value of the temperature difference inside the tent can reach up to 30°C, and the living comfort is very poor.

In addition, the natural convection of the hot air is at the top of the tent, and the cold air is near the ground. It actually feels like the head is hot and the feet are cold. In addition to reducing the comfort, it also causes insufficient effective heat, which greatly affects the protection efficiency of the camping heating stove.
