Inside the condenser, there are three types of cooling elements in the form of air passage profiles, the main elements have a curvature against the target airflow and a vertex behind the stream to avoid tornadoes, which are arranged horizontally and crosswise and on both sides of the wall The condenser, angled cooling elements resemble a staircase, and in the funnel area of the condenser body, there are cubic cooling elements.

[0015] Evaporative cooling systems, due to their low cost and low consumption of electrical energy, are still used in the world for the required amount of cooling, and their indirect type has been reported to be more effective for them due to reducing the temperature without changing the amountof humidity compared to the direct model. Also, from an environmental point of view, these systems, if according to research reports, their market ratio in relation to other air conditioning systems, etc., in the coming years, they will lead to significant savings in fossil fuel consumption and reduce the carbon emissions associated with buildings.

[0016] Since the efficiency of these systems differs in the amount of cooling compared to other methods, it is still possible to achieve a structural model in its condenser that increases the efficiency and increases the cooling rate. Therefore, the purpose of this invention is to increase efficiency and reduce energy consumption in indirect evaporation cooling systems.Solution to Problem

[0017] In the illustration of the air-cooling device (100) presented, the inlet air of the condenser (101 ) is entered by the condenser fan in the upper area of the device (110) from the outside environment first enters the air and water diffuser section of the condenser (120). Then, after passing through the main body and the main cooling part of the condenser (130), through the lower area of the device called the tray section, the air of the condenser (140) is collected and the air from the exhaust area of the condenser (150) is exited to the outside environment as the exhaust air of the condenser (102).

[0018] In an illustration of the way the target air passes, it should be noted that the inlet air of the target (201 ) is blown into the inlet of the condenser (A130) with pressure to cool down, this air flows in two longitudinal directions in parallel and crosswise in the transverse direction, and in the form of the target outlet air (202) for transferable use Would be.

[0019] In this visualization, the incoming air of the target flows inside the condenser as follows:

[0020] First, they pass parallel through the cooling fins (20-130) which are located in a vertical direction with a slight distance from each other, and at the same time, all the main cooling elements (30-130) are surrounded by their small thickness and are covered to the side walls of the condenser body (A130-10 and B 130-10) on its sides, which are where the lateral cooling elements (40-130 and 50-130) are located, and then, due to the type of horizontal arrangement ofthe main cooling elements that are placed in a cross position, they will have their divergent and convergent movement from the side of these main elements in a cross manner.

[0021] In fact, the processed air inside the condenser is divided into parallel batches in a vertical direction by the fins, and each batch will move crosswise by moving through the main elements, and when passing around the flow axis, which is towards the sides, it will collide with the cooling lateral elements, and at the end of the target passage path in the condenser, all the lateral air currents will be ventured towards the center of the flow They are driven.

[0022] The material of the cooling fins as well as all the main and secondary cooling elements are made of highly conductive metals that can be used in the industry, such as copper, brass, aluminum, bronze, etc. The body of the condenser can also be made of plastic in different families.

[0023] In an embodiment of the cooling elements, it should be noted that there are actually profiles that are two soldiers and are located vertically in the condenser and have a purposeful cross-section and shape, in such a way that the main cooling element (30-130) has a cross-section of a circle at an angle of 30 degrees. In fact, this section has a sharp vertex with two equilateral sides (30-120 a), both sides of a Together, they form a vertex, and on the other side they are connected to the two ends of the outward curved curve (B 120-30).

[0024] In fact, the outward convex area is the area facing the incoming air flow of the target, which diverges to the sides while the air current collides with it, and the equilateral part creates a convergent current while preventing this tornado behind the mentioned profile. Since the horizontal arrangement of these elements is in the form of a cross, each convergent flow again collides with the convex curved section to the outside of the next cooling elements, and this divergence and convergence takes place sequentially, and in the meantime, some of the lateral currents are inclined towards the sides of the current, which in order to direct the part and cool the target passing current on both sides of the condenser, first the angled cooling elements (40-130) colliding with the angles of these elements in the position of the main cooling elements adjacent to them, the convergent and divergent current is re-established in thisregion of the condenser and the passivity of the side currents is reduced. Then, as the target flow passes through the middle part of the condenser's length, the air flow enters the condenser's target outlet, which has a curved shape inward, and in these two walls of this region of the condenser, the cubic cooling elements are located, so these elements tilt the lateral target air flow towards the open flow axis and have a cooling effect on these parts of the target air flow. In fact, in general, the lateral cooling elements affect each surface of the target airflow between the two cooling fins and direct them while cooling, and the main cooling elements affect each column of the target airflow between the two cooling fins (Figures 4 and 10).

[0025] In an embodiment of the air and water inlet diffuser section of the condenser, an air and water diffuser (120) are installed in the upper area of the condenser, which has dedicated air passage valves for each of the main (30- 120) and lateral (40-120 and 50-120) cooling elements (Fig. 8). This section of the device has a mesh structure and meshing, with each valve having sloped walls (C20-120) along the vertical in its upper region, all these walls meet each other in a close way and form an edge (120-20 and 120-20 A) (Fig. 7). Therefore, the inlet air flow of the condenser (101) or fan blow is directed to the vents by hitting the edges and the slopes below the ridges, thus preventing any tornadoes or reflected currents from colliding with the surfaces and edges of the vent that have been removed here, which will negatively affect the flow and speed of the airflow.

[0026] In another embodiment of the air and water inlet part of the condenser, at the top of each air vent of the main cooling elements and also on one side of the vents of the side cooling elements, there are water sprinkler nozzles (SO- SOO and 90-300) which are located in the inner tissue of the lower part of the diffuser and are located at the edge of the valves, and from the inside of the tissue, they are connected to the network water ducts ( 20-300, 30-300, 40-300, 50-300, 60-300, and 70-300) are (Figure 9).

[0027] In an illustration of the network water ducts, it should be noted that the ducts become smaller in diameter as they branch towards the nozzles, and the inlet duct to the condenser air and water inlet distributor (300) has three main branches (10-300) upon entering the mentioned section (Figure 7). The twomain lateral branches (20300 and 30-300) and the central main branch also form the two intermediate branches (40-300 and 50-300) that form the main division of the water supply channels (Fig. 9).

[0028] The two main lateral branches are each connected to all the nozzles of the main cooling element valves adjacent to the condenser wall, as well as to the nozzles of the cubic and angled cooling elements. The lateral cooling elements (cuboidal and angled) have several water spraying nozzles (80-300) along their cross-section at regular.

[0029] The important point is that the water that sprays water from the nozzles of the main element’s valves on the inner surface of the curved part of the profile of the mentioned elements, and the amount of water in the water tank (170) devices is such that with the power of the water pump (190) devices, it is more common in each nozzle than spraying and smoothly on the inner wall of the curved part of the main cooling elements and other surfaces. Internal in front of the nozzles in other cooling elements due to the adhesion of water, they form a dynamic water film (300A) and by being adjacent to the inlet air flow of the condenser inside the profile of the cooling elements, they make a vertical up-to-down traversal and enter the condenser’s climate collection tray from under the condenser (Fig. 11 ).

[0030] In an illustration of the condenser's air collection tray, it should be noted that this tray is installed in a sloping shape that as soon as the water and air passing through the condenser falls, it is directed and directed towards the exhaust part of the air and water with a separating surface (160) the width of the condenser (Fig. 2), the air is poured into the outside environment and the water is poured into the water tank.Advantageous Effects of Invention
