Tent capable of being rapidly cooled down

The utility model relates to a tent, in particular to a tent capable of feeding cold air or hot air and being rapidly heated or cooled down. The tent comprises a piece of tent cloth and a support, wherein the support comprises a plurality of vertical rods and a plurality of top transverse rods; one hollow vertical rod is used as an air inlet pipe, and the air inlet pipe is provided with an air inlet hole penetrating the wall of the air inlet pipe; and the tent also comprises an air distribution device which is arranged on the upper part of the support, the air distribution device is connected with the air inlet pipe, and the air inlet hole is communicated with a refrigeration device. By adopting the scheme, the support is used as the air inlet pipeline, and the traditional air conditioner window-type ventilation way is changed, so that the structure is simpler; and the air distribution device is arranged on the top of the support, thus realizing an effect for rapidly cooling and uniformly cooling.
