Description
本發明與建築物結構有關,尤指一種建築物之通風降溫結構。The invention relates to a structure of a building, and more particularly to a ventilation and cooling structure of a building.
按,一般常見許多建築物使用鐵皮搭建屋頂,由於其金屬材質而有容易吸熱升溫的特性,連帶使室內溫度提高,若通風機制不夠完善,將導致室內環境非常悶熱。According to the general practice, many buildings use iron sheets to build roofs. Due to their metal materials, they have the characteristics of easy heat absorption and temperature rise. As a result, the indoor temperature is increased. If the ventilation mechanism is not perfect, the indoor environment will be very stuffy.
為了解決上述問題,一種習知的通風降溫結構如第4、5圖所示者,其於屋頂3沿屋脊延伸方向開設有一通風口31,且於屋頂3下方設有一隔板4,屋頂3與隔板4之間形成有一散熱通道41,藉此可令室內的熱空氣經由該散熱通道41流向該通風口31並排出,達到降溫之目的。更進一步地,上述習知結構更於該隔板4上設有複數個長排狀通孔42,以供室內熱空氣經各通孔42進入該散熱通道41。In order to solve the above problems, a conventional ventilation cooling structure, as shown in FIGS. 4 and 5, has a vent opening 31 in the direction in which the roof 3 extends along the ridge, and a partition 4 is provided below the roof 3, and the roof 3 is provided. A heat dissipating passage 41 is formed between the partitions 4, so that hot air in the room can flow to the vents 31 through the heat dissipating passages 41 and discharge, thereby achieving the purpose of cooling. Further, the above-mentioned conventional structure is provided with a plurality of long-row-shaped through holes 42 on the partition plate 4 for the indoor hot air to enter the heat dissipation passage 41 through the respective through holes 42.
惟如第5圖所示,上述習知結構中,各通孔42之孔徑自該隔板4之頂面43至底面44係為相同一致的寬度,如此一來,並不能有效幫助氣流穿過各通孔42而進入該散熱通道41,通風降溫的效率不彰,因而無法改善室內空間的悶熱情形。However, as shown in FIG. 5, in the above-mentioned conventional structure, the aperture of each of the through holes 42 has the same uniform width from the top surface 43 to the bottom surface 44 of the partition 4, so that the airflow cannot be effectively assisted. Each of the through holes 42 enters the heat dissipation passage 41, and the efficiency of ventilation and cooling is not good, so that the sultry situation of the indoor space cannot be improved.
有鑑於此,如何改進上述問題即為本發明所欲解決之首要課題。In view of this, how to improve the above problems is the primary problem to be solved by the present invention.
本發明之主要目的在於提供一種建築物通風降溫結構,其形成一可阻隔室外熱空氣往室內傳遞之空間,藉以減緩室內溫度上升;又該空間更可加強氣流的對流作用,使室內熱空氣得以向外排出,以維持室內的舒適度。The main object of the present invention is to provide a ventilation and cooling structure for a building, which forms a space for blocking outdoor hot air to be transmitted indoors, thereby mitigating the temperature rise of the room; and the space can further enhance the convection of the airflow, so that the indoor hot air can be Discharge outward to maintain indoor comfort.
為達前述之目的,本發明提供一種建築物通風降溫結構,其設於一建築物之屋頂,該屋頂呈尖脊狀,且沿屋脊延伸方向設有一通風口;該屋頂設有一位於該建築物內部之隔板,該隔板與該屋頂之間形成有一對流換氣空間,並具有一位置較低之進風口及一位置較高且對應該通風口之出風口;該隔板具有一頂面及一底面,且該隔板設有複數個貫穿該頂面及該底面之通孔,其特徵在於:各通孔形成自該底面朝該頂面漸縮之錐狀,其於該頂面形成有一小徑口,且於該底面形成有一大徑口。For the purpose of the foregoing, the present invention provides a building ventilation and cooling structure which is disposed on a roof of a building having a pointed ridge shape and a vent opening along the ridge extending direction; the roof is provided with a building An internal partition, a pair of flow ventilation spaces are formed between the partition and the roof, and has a lower air inlet and a higher air outlet corresponding to the air outlet; the partition has a top surface And a bottom surface, wherein the partition plate is provided with a plurality of through holes penetrating the top surface and the bottom surface, wherein each of the through holes is formed in a tapered shape which is tapered from the bottom surface toward the top surface, and is formed on the top surface There is a small diameter opening, and a large diameter opening is formed on the bottom surface.

而本發明之上述目的與優點,不難從下述所選用實施例之詳細說明與附圖中獲得深入了解。The above objects and advantages of the present invention will be readily understood from the following detailed description of the embodiments of the invention.
請參閱第1、2圖,所示者為本發明提供之建築物通風降溫結構,其與建築物之屋頂1搭配設置。於本實施例中,所述的屋頂1可呈尖脊狀,且沿屋脊延伸方向設有一通風口11,使建築物之室內空間12連通至室外。而該屋頂1於該通風口11之上方設有一遮雨蓋13,以防下雨時雨水經該通風口11潑入室內空間12。該遮雨蓋13沿屋脊延伸,且於兩側分別設有一開口14。Please refer to Figures 1 and 2 for the ventilation and cooling structure of the building provided by the present invention, which is arranged in combination with the roof 1 of the building. In the present embodiment, the roof 1 may have a ridge shape, and a vent 11 is provided along the ridge extending direction to connect the indoor space 12 of the building to the outside. The roof 1 is provided with a rain cover 13 above the vent opening 11 to prevent rainwater from splashing into the indoor space 12 through the vent 11 when it rains. The rain cover 13 extends along the ridge and is provided with an opening 14 on each side.
承上,該屋頂1於該建築物內部設有一隔板2,該隔板2以複數個連接塊21連接該屋頂1,並藉此與該屋頂1相隔而形成有一對流換氣空間22。於本實施例中,該隔板2依該屋頂1之斜度對應設置,且其一端延伸至該通風口11之下方,並形成一位置較高之出風口23,另一端則形成一位置較低之進風口24。The roof 1 is provided with a partition 2 inside the building, and the partition 2 is connected to the roof 1 by a plurality of connecting blocks 21, and thereby forms a pair of flow ventilation spaces 22 spaced apart from the roof 1. In this embodiment, the partition plate 2 is correspondingly disposed according to the inclination of the roof 1, and one end thereof extends below the venting opening 11 and forms a higher position air outlet 23, and the other end forms a position. Low air inlet 24
更進一步地,界定該隔板2具有一面對該對流換氣空間22之頂面25及一面對室內空間12之底面26,該隔板2上設有複數個貫穿該頂面25及該底面26之通孔27,其中各通孔27可為圓孔或方孔,且如第3圖所示,各通孔27於軸向上形成自該底面26朝該頂面25漸縮之錐狀,並於該頂面25形成有一小徑口271,於該底面26形成有一大徑口272。各通孔27於該隔板2上形成均勻的分布。Further, the partition 2 defines a top surface 25 of the convection ventilation space 22 and a bottom surface 26 facing the indoor space 12, and the partition 2 is provided with a plurality of through the top surface 25 and the The through hole 27 of the bottom surface 26, wherein each of the through holes 27 may be a circular hole or a square hole, and as shown in FIG. 3, each of the through holes 27 is formed in a tapered shape which is tapered from the bottom surface 26 toward the top surface 25 in the axial direction. A small diameter opening 271 is formed in the top surface 25, and a large diameter opening 272 is formed in the bottom surface 26. Each of the through holes 27 forms a uniform distribution on the separator 2.
藉由上述結構,當陽光照射於建築物的屋頂1時,首先由於空氣的導熱係數甚低,因而屋頂1的高溫會受阻於該對流換氣空間22,難以將熱能傳遞至室內空間12,藉此初步地減緩室內空間12溫度上升的幅度。接著,該對流換氣空間22內的空氣被屋頂1加熱後,因密度降低之故產生向上流動的現象,並經該出風口23及該通風口11流出室外;另一方面,室內空間12之空氣將經該進風口24遞補流入該對流換氣空間22,據此形成對流現象。上述對流現象可藉由排出熱空氣以促進室內空間12的通風,進而除去室內空間12的悶熱感。With the above structure, when sunlight is applied to the roof 1 of the building, firstly, since the thermal conductivity of the air is very low, the high temperature of the roof 1 is blocked by the convection ventilation space 22, and it is difficult to transfer the heat energy to the indoor space 12, This initially slows down the temperature rise of the indoor space 12. Then, after the air in the convection ventilation space 22 is heated by the roof 1, the phenomenon of upward flow occurs due to the decrease in density, and flows out through the air outlet 23 and the vent 11; on the other hand, the indoor space 12 Air will replenish through the air inlet 24 into the convection ventilation space 22, thereby forming a convection phenomenon. The convection phenomenon described above can promote the ventilation of the indoor space 12 by discharging hot air, thereby removing the sultry feeling of the indoor space 12.
此外,室內空間12的空氣更可經該隔板2之各通孔27進入該對流換氣空間22,以實施上述的對流現象,且各通孔27更可利用其形狀進一步地有效促進空氣的流動。細言之,由於各通孔27依氣流流動方向形成漸縮之錐狀,使氣流在流動過程中被加壓,而以較高的速度從該小徑口271排入該對流換氣空間22。此時該隔板2之兩側以該對流換氣空間22形成相對低壓區,而室內空間12則形成相對高壓區,如此將產生一自然的驅動力而可驅使空氣自高壓區往低壓區流動,進而有效促進流動,提升對流通風的降溫效果。In addition, the air in the indoor space 12 can enter the convection ventilation space 22 through the through holes 27 of the partition 2 to implement the convection phenomenon described above, and each of the through holes 27 can further effectively promote the air by using the shape thereof. flow. In detail, since each of the through holes 27 is formed into a tapered shape in the flow direction of the airflow, the airflow is pressurized during the flow, and is discharged from the small diameter port 271 into the convection ventilation space 22 at a relatively high speed. . At this time, the two sides of the partition 2 form a relatively low pressure zone with the convection ventilation space 22, and the indoor space 12 forms a relatively high pressure zone, which will generate a natural driving force to drive the air from the high pressure zone to the low pressure zone. , thereby effectively promoting the flow and improving the cooling effect of convection ventilation.
惟,以上實施例之揭示僅用以說明本發明,並非用以限制本發明,故舉凡等效元件之置換仍應隸屬本發明之範疇。However, the above description of the embodiments is merely illustrative of the invention and is not intended to limit the invention, and the replacement of equivalent elements is still within the scope of the invention.
綜上所述,可使熟知本項技藝者明瞭本發明確可達成前述目的,實已符合專利法之規定,爰依法提出申請。In summary, it will be apparent to those skilled in the art that the present invention can achieve the foregoing objectives and is in accordance with the provisions of the Patent Law.
