NOVELTY - The utility model claims an integrated simple assembled wind pipe, the integrated simple assembled wind pipe comprises a shell body with two ends opening and a graphene thin plate with full heat exchange effect set in the outer shell, graphene sheet divides the outer shell into an air inlet pipe and an exhaust pipe; The integrated simple assembled wind pipe of the utility model is combined together, the double-pipe installation is simplified into single pipeline installation, greatly reducing the time and labour cost, and not simply splicing the two wind pipes together, but using graphene thin plate, capable of increasing the heat efficiency, pre-heating the new wind entering the room in winter; pre-cooling the new wind entering the room in summer; reaching the effect of saving energy.
