Description

Technical Field

[0001] This application relates to the field of air cooler technology, and specifically discloses an anti-condensation air collector with no internal dead zone. Background Technology

[0002] Air coolers are heat exchangers that use air to cool hot fluids. In the petrochemical and other fields, the demand for energy-saving and water-saving equipment such as dry air coolers and evaporative air coolers is gradually increasing. However, some equipment is used in very harsh environments, such as salt spray. When salt spray comes into contact with water, it produces an electrochemical reaction that can cause serious corrosion to the equipment.

[0003] The corrosion mechanism of salt spray upon contact with water is mainly due to chloride ions penetrating the oxide and protective layers of the metal surface and undergoing an electrochemical reaction with the internal metal. The main component of salt spray is sodium chloride (NaCl). When salt spray settles onto the metal surface, sodium chloride decomposes into Cl- ions and Na+ ions. These ions, under the influence of moisture, form a salt water film that surrounds the entire metal surface, causing the metal surface to form the two poles of a galvanic cell, thereby triggering an electrochemical reaction and resulting in corrosion.

[0004] Current conventional salt spray corrosion prevention measures include: forming a protective film through surface treatment technologies such as electroplating and spraying to isolate chloride ions from direct contact with metal, reduce humidity and salt content in the environment, prevent salt spray from directly contacting the metal surface, and prevent the formation of water droplets (water droplets formed by factors such as rain inside the air cooler are not considered at this time).

[0005] Traditional air cooler air collectors such as Figures 1 to 3 As shown, its overall structure consists of a connecting plate 1a, an air collector body 2a, and a base 3a. The connecting plate 1a is used to connect with the air duct of the air cooler, as shown in the figure. Figure 2 and Figure 3 As shown, the connecting plate 1a connecting the air collector and the air duct extends inward from the center line, resulting in a dead zone inside. Hot air circulates in the dead zone and cannot be discharged in time. External cold air comes into contact with the outer wall of the dead zone, causing the cold air and hot air to exchange heat. Prolonged heat exchange causes small water droplets to precipitate on the hot air side and adhere to the inner wall of the air collector or drip onto the heat exchange tube bundle and structural components. Combined with salt spray, this causes electrochemical corrosion on the inner wall of the air collector, heat exchange tube bundle, and structural components, affecting the overall service life of the air cooler. Therefore, in view of this, the inventor provides an anti-condensation air collector without an internal dead zone to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem that traditional air collectors have dead zones inside, where external cold air and internal hot air exchange heat in the dead zones, causing small water droplets to precipitate and adhere to the inner wall of the air collector or drip onto the heat exchange tube bundle and structural components. This makes the inner wall of the air collector, heat exchange tube bundle, and structural components prone to electrochemical corrosion, affecting the overall service life of the air cooler.

[0007] To achieve the above objectives, the basic solution of this utility model provides an anti-condensation fan with no internal dead zone, comprising:

[0008] The flange is connected to the air duct of the air cooler.

[0009] The air collector body includes several plates that are connected in sequence, and the top of each plate is smoothly and tightly connected to the inner wall of the flange.

[0010] The base is located at the bottom of the air collector body and is used to support the air collector body and the flange.

[0011] Furthermore, both the flange and the base are provided with several mounting holes.

[0012] Furthermore, the mounting hole is any one or more combinations of a through hole, a threaded hole, or a countersunk hole.

[0013] Furthermore, the base has an L-shaped cross-section, the top sidewall of the base is connected to the bottom of the air collector body, and the mounting hole is located at the bottom of the base.

[0014] Furthermore, the top of each sheet is provided with a straight edge that is smoothly and tightly connected to the inner wall of the flange, and adjacent straight edges are tightly connected.

[0015] Furthermore, the connection between the straight edge and the sheet body and the flange is smooth.

[0016] Furthermore, a protective layer is provided on the walls of the flange, the air collector body, and the base.

[0017] Furthermore, the protective layer is a hot-dip galvanized layer, a painted layer, or an electroplated layer.

[0018] Furthermore, the base includes several connectors that are connected end to end to form a polygonal shape, and the connectors are any one of angle steel, rectangular tube, I-beam or channel steel.

[0019] Furthermore, the coaxiality tolerance of the flange and the air collector body shall not exceed 0.03 mm;

[0020] The parallelism tolerance of the connection surface between the flange and the air duct of the air cooler shall not exceed 0.08 mm.

[0021] The principle and effect of this solution are as follows:

[0022] Compared with the prior art, this utility model designs the flange connecting the air collector and the air duct to extend outward from the center line to avoid the formation of dead zones inside the air collector. This allows hot air to be discharged from the air collector in a timely manner, preventing hot air from staying inside the air collector for too long, which would cause hot air to precipitate water droplets upon cooling, leading to electrochemical corrosion due to salt spray. This effectively solves the problem of traditional air collectors having dead zones inside, where external cold air and internal hot air exchange heat in the dead zones, causing small water droplets to precipitate and adhere to the inner wall of the air collector or drip onto the heat exchange tube bundle and structural components. This makes the inner wall of the air collector, heat exchange tube bundle, and structural components prone to electrochemical corrosion, affecting the overall service life of the air cooler.

[0030] Figure 7 It shows Figure 6 Enlarged diagram of part A in the middle. Detailed Implementation

[0031] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0032] The reference numerals in the accompanying drawings include: the connection plate 1a of the existing air collector, the air collector body 2a of the existing air collector, the base 3a of the existing air collector, the flange 1, the air collector body 2, and the base 3.

[0033] An anti-condensation fan with no internal dead zone, implementing, for example Figures 4 to 7 As shown: It consists of flange 1, air collector body 2 and base 3.

[0034] Flange 1 is used to connect with the air duct of the air cooler. Flange 1 is made by slowly processing angle steel into a ring shape using a special rolling bending machine, and then welding the ends together. The use of angle steel is similar to the bending of sheet metal parts, which can play a good structural reinforcement role. The flange 1 formed in this way is conducive to the overall structure of bearing the upper air duct and is less likely to deform the lower air collector body 2 due to the load above. Of course, in other embodiments, the forming steel of flange 1 can also be rectangular tube, I-beam, channel steel, and similar sheet metal parts, with the amount of steel used ranging from 1 to 100. Flange 1 is provided with mounting holes for mating with the air duct of the air cooler. The mounting holes are through holes and are fixed with bolts, nuts, and washers. Of course, in other embodiments, the mounting holes can also be threaded holes, countersunk holes, etc., with varying hole diameters. Quantity: 8 to 100 pieces; Parallelism tolerance of the connection surface between flange 1 and the air duct of the air cooler shall not exceed 0.08 mm.

[0035] The air collector body 2 comprises several tightly connected plates, ranging from 4 to 100. Each plate has a straight edge at its top that smoothly and tightly connects to the bottom of the inner wall of the flange 1, with adjacent straight edges tightly connected. Each plate is formed by a bending machine and then welded in sequence to form a lid-shaped air collector body 2. Each additional bending line enhances the load-bearing capacity and bending resistance of the entire air collector body 2. The straight edges also significantly strengthen the load-bearing capacity of the entire air collector. The lower part of the inner wall of the flange 1 is fully welded to the top of the air collector body 2, and the coaxiality tolerance between the flange 1 and the air collector does not exceed 0.03 mm.

[0036] The base 3 is formed by welding four angle steel bars connected end to end to form a rectangular shape. The use of angle steel makes the base 3 structurally more stable and less prone to bending deformation. In other embodiments, the steel used for the base 3 can also be rectangular tubing, I-beams, channel steel, or similar sheet metal parts, with the quantity of steel used ranging from 4 to 100. The base 3 also has mounting holes, which are through holes and secured with bolts, nuts, and washers. In other embodiments, the mounting holes can also be threaded holes, countersunk holes, etc., with varying diameters. The quantity is 8 to 100 pieces; the parallelism tolerance of the connection surface between flange 1 and the air duct of the air cooler does not exceed 0.08. The cross-section of the base 3 is L-shaped, so that the top side wall of the base 3 is fully welded to the bottom of the air collector body 2, ensuring that the center of the air collector coincides with the center of the base 3, and the mounting hole is located at the bottom of the base 3.

[0037] After the flange 1, the air collector body 2, and the base 3 are welded, they are ground to ensure a smooth transition at the joints between the straight edges and the plate, between the straight edges and the flange 1, and between the plate and the base 3. Following grinding, the entire assembly undergoes hot-dip galvanizing to form a protective layer, significantly improving its appearance and service life. Alternatively, in other embodiments, the protective layer can be formed by painting or electroplating.

[0038] In this embodiment, the flange 1 connecting the air collector and the air duct extends outward from the centerline to avoid creating a dead zone inside the air collector. This allows hot air to be discharged from the air collector in a timely manner, preventing hot air from staying inside the air collector body 2 for too long, which would cause hot air to precipitate water droplets upon cooling, leading to electrochemical corrosion due to salt spray. This effectively solves the problem of traditional air collectors having dead zones inside, where external cold air and internal hot air exchange heat in the dead zone, causing small water droplets to precipitate and adhere to the inner wall of the air collector or drip onto the heat exchange tube bundle and structural components. This makes the inner wall of the air collector, heat exchange tube bundle, and structural components prone to electrochemical corrosion, affecting the overall service life of the air cooler.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
