Embodiment Construction
[0013] Such as figure 1 , the exhaust duct of the high-rise residential building of the present embodiment comprises: be located at the top of the exhaust duct 1, be a hollow transparent passage 3 (preferably made of glass or transparent plastic), be located at the non-powered air cap on the upper end of the transparent passage 3. power hood2. The transparent channel 3 includes a hollow, upper and lower symmetrical upper frustum 31 and lower frustum 32 . This product utilizes solar energy to heat the air in the transparent channel 3, and the hot air rises, increasing the effect of pulling wind. Wherein, sunlight can directly shoot into the transparent channel from the slope of the transparent channel to heat the air, and the surrounding slopes of the transparent channel 3 can absorb light at any time during the day. The exhaust channel 1, the transparent channel 3 and the unpowered hood 2 are coaxially arranged.

The invention provides an unpowered cowl for an exhaust channel. The unpowered cowl comprises a hollow transparent channel arranged on the top of the exhaust channel, and an unpowered cowl body arranged on the end opening of the top of the transparent channel. The bottom end opening of the transparent channel is arranged on the top end opening of the exhaust channel. The transparent channel comprises frustums which are hollow, symmetrical from top to bottom and integrally arranged. According to the unpowered cowl for the exhaust channel in a high-rise building, the hollow transparent channel is added on the basis of a conventional unpowered cowl. Therefore, sunlight can directly shine into the transparent channel through a bevel of an upper frustum of the transparent channel to heat air, and the wind drafting effect can be more remarkable due to a rising character of the hot air. The sidewall of a lower frustum is opposite to a roof, thermal radiation of the roof can enter the transparent channel from the sidewall of the lower frustum, and heating of the air in the transparent is further facilitated.
Description
technical field [0001] The invention relates to a non-powered air cap for an exhaust channel of a high-rise residence. Background technique [0002] The unpowered hood is to use the natural wind speed of nature to drive the turbine of the fan to rotate and the principle of indoor and outdoor air convection to accelerate and transform any parallel air flow into a vertical air flow from bottom to top to improve indoor ventilation. A kind of device, it does not need electricity, has no noise, can run for a long time, and removes indoor heat, moisture and foul air. It is rationally installed on the top of the roof according to the natural law of air and the principle of air flow, and can quickly discharge indoor heat. And dirty gas, improve the indoor environment. [0003] Due to the influence of the outdoor wind flow, the conventional unpowered hood located at the top of the exhaust duct sometimes has a less than ideal effect of pulling out the wind, so that the smell in the i...
