Description

Thermal power ventilation device

Technical Field

The invention relates to a ventilation device, in particular to a thermal power ventilation device.

Background

With the development of the building industry, the building energy consumption is more and more concerned by the industry, and the reduction of the building energy consumption becomes a key point which must be considered by the industry at present. Wherein, the ventilation mode is an effective mode for reducing the energy consumption of the building. The current common mode is natural ventilation or forced ventilation. The natural ventilation mode is realized comparatively complicacy, and the effect is less than ideal, and mandatory ventilation mode needs additionally to provide power, needs electricity to drive the fan mostly, realizes the ventilation, extravagant electric energy. If the heat energy on the surface of the building can be utilized to generate electricity or power to realize ventilation, the effects of not using electricity and realizing forced ventilation can be achieved.

There is a need for an apparatus that can convert thermal energy into electricity or kinetic energy, the most ideal apparatus being a thermoelectric generator, which is an apparatus that can generate electrical energy in a temperature-differential environment, and there are two main types at present: a semiconductor generator typically manufactured in semiconductor thermoelectric generation modules; the other is a low temperature difference stirling engine. Both of these devices can operate at low temperature differentials and are ideal power plants.

If the energy-saving air conditioner can be combined with a temperature difference generator to realize forced ventilation of a building, a better energy-saving effect can be generated.

Disclosure of Invention

To achieve the above objects, the present invention provides a thermal power ventilating apparatus. The invention combines the temperature difference generator, and the temperature difference generator can generate electricity under the temperature difference to drive the fan of the motor to operate (or directly generate power to drive the fan to operate) to realize forced ventilation.

The scheme adopted by the invention for realizing the technical problems is as follows: the thermal power ventilation device comprises a heat conducting plate, a temperature difference generator and a ventilation cavity, wherein the heat conducting plate is connected with the hot end of the temperature difference generator, the temperature difference generator is connected with a fan, and the ventilation cavity is provided with a ventilation opening; the fan is arranged at the position of the ventilation opening.

The invention has the advantages that the collected heat on the surface of the building is directly utilized to drive the thermoelectric generator to operate, so that the fan is driven to operate, forced ventilation is realized, and the effect of energy conservation is achieved.
