Detailed Description
The present invention is further illustrated in the accompanying drawings and detailed description which are to be understood as being merely illustrative of the invention and not limiting of its scope, and various modifications of the invention, which are equivalent to those skilled in the art upon reading the invention, will fall within the scope of the invention as defined in the appended claims.
As shown in fig. 1 and 2, a wind energy double-gradually-tube passive cooling system comprises a first reducing tube 1 and a second reducing tube 2 which are oppositely arranged on the oblique opposite sides of a room. The first reducing pipe 1 is positioned at the bottom of a room, and the second reducing pipe 2 is positioned at the top of the room. One end of the first reducing pipe 1 with the larger diameter faces the sun and is opened to serve as a wind catching port, the other end of the first reducing pipe 1 faces the sun and is closed, and a water tank 3 is arranged in the first reducing pipe 1; one end of the second reducing pipe 2 with larger diameter is back-exposed and is opened to serve as an air outlet, and the other end of the second reducing pipe is exposed and is closed.
A plurality of shrinkage holes 4 are formed in the first shrinkage pipe 1 and the second shrinkage pipe 2; the diameter of the tapered hole 4 gradually decreases or increases from one end to the other end; the larger diameter end of the tapered hole 4 faces the inside of the room, and the other end faces the outside of the room.
The first reducer 1 and the second reducer 2 can concentrate the flow direction of the air flow, and when passing through the tapered hole 4, the cross-sectional area of the pipe gradually decreases due to the decrease in the aperture, and under the condition that the flow rate of the air is unchanged, the air flow rate increases, resulting in an increase in the speed of the air flow flowing into the room, and accelerating the ventilation efficiency.
The tapered hole 4 in the first reducer 1, with the larger diameter end facing the outside of the room, i.e. facing the sink 3, is advantageously designed to catch and concentrate the air flow in the pipe. By reducing the aperture, the air flow is guided to flow indoors, and the included angle between the guided air flow and the air flow direction in the reducing pipe is an acute angle, so that the loss of wind energy is reduced. Finally, a fresh air flow is introduced into the chamber through the smaller diameter end.
The larger diameter end of the tapered hole 4 on the second reducer 2 faces the inner side of the room, namely faces the ground, so that the rising hot air in the room can be captured and collected, and the hot air is guided to flow towards the air outlet along with the reduction of the aperture, finally flows through the smaller diameter end of the tapered hole 4, so that the hot air is converged into the second reducer 2, a larger air flow is formed in the pipe, and is discharged outdoors through the air outlet.
The other section of the first reducer 1 is closed so that the flow of cold, moist air can only flow indoors through the first reducer 1 along the tapered bore 4 under the influence of air pressure. One end of the second reducer 2 is closed, so that the indoor hot air flow can only pass through the second reducer 2 along the tapered hole 4 to be discharged outwards. Meanwhile, as the end with larger diameter of the tapered hole 4 of the first reducing pipe 1 faces outdoors, namely faces the ground, and the end with smaller diameter faces indoors and penetrates through the first reducing pipe 1, the possibility of air in the second reducing pipe 2 flowing backwards is greatly reduced.
The implementation process of the invention is as follows: the water tank 3 is a natural ventilation evaporation water tank, water is discharged in the water tank, wind enters from the wind catching port, and air flow is accelerated to evaporate water according to the air circulation principle. The diameter of the wind catching opening is larger and the sun faces, and the evaporation rate of water is also accelerated under the heating of sunlight. The air flows into the room through the tapered holes 4 under the action of wind pressure, and is mixed with the indoor hot air after reaching the room. According to the thermodynamic principle: the hot air with small density rises and is converged into the second reducing pipe 2 through the reducing hole 4 after rising, and finally the indoor hot air is discharged from the air outlet.
Further, the sections of the first reducing pipe 1 and the second reducing pipe 2 are right-angle sectors. The first reducing pipe 1 and the second reducing pipe 2 are matched with the right-angle corner. And does not occupy the middle space of the room. The hidden effect does not affect the visual appearance of the room.
Further, the cross section of the first reducing pipe 1 or the second reducing pipe 2 is a right-angle circular arc. The right-angle circular arc forms a right-angle fan shape by utilizing right-angle edges of the wall corners. Saving the material of the reducer 1 and reducing the production cost.
Furthermore, the water tank 3 is located at the bottom of the first reducing pipe 1 and is equal to the first reducing pipe 1 in length. So that the length of the cross section of the water tank 3 is longest, i.e. the cross section area is increased, which is advantageous for water evaporation.
Further, the distribution density of the tapered holes 3 gradually decreases as the diameter of the first reducer 1 or the second reducer 2 gradually decreases. Further, the distribution density of the tapered holes gradually decreases as the diameter of the first reducer 1 or the second reducer 2 gradually decreases. Under the condition that the wind pressure and the gas volume are certain, when the air flow passes through the first reducing pipe 1 and the second reducing pipe 2, the air outlet speed of the convergent holes 4 close to the air catching opening or the air outlet is high, the air outlet speed of the convergent holes 4 far away from the air catching opening or the air outlet is low, the purpose of reducing the speed of the air flow passing through the front end of the first reducing pipe 1 or the second reducing pipe 2 is achieved by increasing the total flow passing area of the air at the front end of the first reducing pipe 1 or the second reducing pipe 2, namely the number of the convergent holes 4, the air outlet speed of the front section and the rear section of the first reducing pipe 1 or the second reducing pipe 2 is average, and the air flow from bottom to top is easy to form indoors.
The invention utilizes wind energy and solar energy to cool and humidify the indoor air caused by the evaporation of water in the water tank; the indoor hot air is discharged out of the room by utilizing the principle that the cold air of the indoor air flow sinks and the hot air flow rises, so that the purposes of cooling and humidifying are achieved.
