Description

Building ventilation cooling structure

The invention relates to a structure of a building, and more particularly to a ventilation and cooling structure of a building.

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.

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.

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.

In view of this, how to improve the above problems is the primary problem to be solved by the present invention.

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.

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.

In an embodiment, the roof is provided with a rain cover above the vent, and the rain cover is respectively provided with an opening on both sides of the ridge extending direction.

In an embodiment, each of the through holes is a circular hole or a square hole.

The above objects and advantages of the present invention will be readily understood from the following detailed description of the embodiments of the invention.

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.

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

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.

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.

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.

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.

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.
