Natural ventilation device for building

Abstract

The invention relates to a natural ventilation device for a building. The natural ventilation device for the building mainly comprises a top end exhaust system, an upper slope exhaust system and an upper plane exhaust system. According to the structural design of the three sets of exhaust systems, the three sets of exhaust systems are mainly erected at the joint of bevel edges of a roof, the slope of the roof or the plane of the roof, exhaust outlets are formed in the arranged positions, outer exhaust outlets are formed in the uppermost ends of the exhaust systems, and long and short baffles are additionally arranged among the outer exhaust outlets; a plurality of water guiding plates are arranged at the lower ends of the outer exhaust outlets, the water guiding plates can be single water guiding plates or double water guiding plates or the double water guiding plates are matched with a plurality of auxiliary guiding plates, and water outlet structures are formed in the positions, connected with an outer cover body, of the water guiding plates. Therefore, according to the natural ventilation device for the building, hot air in the building is naturally exhausted, more than half of rainwater can be effectively prevented from being directly sprayed into an exhaust device through the design of file plates of the exhaust systems, and a good waterproof effect can be achieved by matching with the drainage design of the guiding plates.

Description

technical field [0001] The invention relates to a natural ventilation device for buildings, specifically a device that can achieve the natural discharge of indoor hot air through design. Background technique [0002] Since the interior of the iron-clad buildings of factories or warehouses is stuffy and hot, which leads to poor working environment, most operators will install exhaust fans on the top of the buildings to allow the air in the buildings to circulate and achieve the effect of cooling. [0003] However, the fan needs to be driven by electricity, which will increase the operating cost, and if it rains, the fan device cannot effectively remove the rainwater, which may cause water to enter the building, so it should be solved and improved. Contents of the invention [0004] In view of this, one object of the present invention is to provide a kind of building natural ventilation device, mainly by the principle of air flow, when making gas flow, the air outlet inside ...
