Description

Technical Field

[0001] This application relates to the technical field of air coolers, and in particular to an air cooler inlet water baffle structure and an air cooler. Background Technology

[0002] Evaporative air coolers are a type of refrigeration equipment widely used in cold storage facilities. Their refrigeration principle involves refrigerant circulating within heat exchange tubes. Indoor air, driven by a fan, passes through the heat exchange components, is cooled, and is then blown out from one side of the fan. Evaporative air coolers require defrosting after a period of operation. Common defrosting methods include water defrosting, electric defrosting, and heat transfer defrosting.

[0003] In the structure of water-based defrosting evaporative air coolers, an internal spray structure is used. Because water is prone to splashing during the spraying process, an inclined baffle is often installed on the side of the air inlet. For example, the utility model patent with authorization announcement number CN208952512U discloses an evaporative air cooler with a baffle. For this type of evaporative air cooler, since the temperature on the side near the air inlet is relatively low during operation, some air is prone to condensing into water droplets after contacting the baffle. The water droplets fall into the water collection tray at the bottom under the guidance of the baffle. The baffle can reduce the rapid frost formation on the surface of the heat exchange tube, but at the same time, the surface of the baffle is also prone to frost formation. During the defrosting process, since the baffle is placed externally, the spray water cannot effectively wash away the frost layer on the surface of the baffle, requiring manual defrosting operation, which reduces the defrosting efficiency. Utility Model Content

[0004] In order to achieve efficient defrosting of the baffle plate, the primary objective of this application is to provide a baffle structure for the air inlet of a cold air blower.

[0005] The air inlet water-blocking structure for an evaporative cooler provided in this application adopts the following technical solution: A water-blocking structure for an air cooler includes: Side panels are located on both sides of the air inlet of the cabinet. At least one baffle plate is connected between the two side plates; The heating element is installed on the end face of the baffle plate away from the air inlet; and At least one closed panel is connected between the two side panels; The sealing plate is placed on the side of the baffle plate away from the air inlet, and a heating cavity for accommodating the heating pipe is formed between the sealing plate and the baffle plate.

[0006] Preferably, the sealing plate is slidably connected to the two side plates.

[0007] Preferably, the side plate has a sliding opening, and the sealing plate is disposed in the sliding opening.

[0008] Preferably, the sealing plate includes a sealing section and a limiting section extending outward from one end of the sealing section; the side plate also has a limiting port that connects to the sliding port, and the limiting section is engaged in the limiting port.

[0009] Preferably, the baffle plate includes a baffle section and an upper extension section and a lower extension section connecting the baffle section, a portion of the limiting section abuts against the upper extension section, and the end face of the closing section abuts against the lower extension section.

[0010] Preferably, the water baffle further includes an installation section connected to both sides of the water baffle section, the installation section abutting against the side plate and connected to the side plate.

[0011] Preferably, the water baffle plate has a groove protruding towards the air inlet on one end face away from the air inlet, and the heating tube is disposed in the groove.

[0012] Preferably, the shape of the groove matches the shape of the heating tube.

[0013] Preferably, the heating element is a coil, and the heating element is connected to the baffle plate by a pipe clamp.

[0014] In order to achieve efficient defrosting of the water baffle, the second objective of this application is to provide a cold air blower.

[0015] The air cooler provided in this application adopts the following technical solution: A cold air blower includes the aforementioned air inlet and water baffle structure.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. By adding a heating tube to the back of the baffle plate, the heating tube can effectively defrost the frost layer condensed on the surface of the baffle plate during the defrosting operation, thereby improving the defrosting efficiency. 2. The enclosed plate reduces the exposure of the heating element, thus reducing safety hazards. Secondly, the two plates, when in contact with the baffle plate, form a heating chamber, which reduces heat loss from the heating element during defrosting and further improves the defrosting effect. 3. The sealing plate adopts a detachable sliding connection structure, which can quickly realize the assembly and disassembly between the sealing plate and the side plate. At the same time, the upper limit section and the limiting port of the sealing plate can quickly position the sealing plate. Furthermore, the limiting section abuts against the upper extension section of the baffle plate, and the lower edge of the sealing plate abuts against the lower extension section. This not only improves the sealing performance of the heating chamber, but also further improves the installation and limiting efficiency of the sealing plate. Attached Figure Description

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] Figure 1 and Figure 2 The diagram illustrates the structure of an air cooler, including a cabinet and a heat exchange assembly installed within the cabinet. One side of the cabinet has an open air inlet 11, and at least one fan 50 is installed on the other side. The fan 50 draws external air into the cabinet through the air inlet 11, flows through the heat exchange assembly, and is then blown out from the fan 50. In this embodiment, the heat exchange assembly includes multiple heat exchange tubes 40, through which refrigerant is circulated. The flow of the refrigerant removes heat from the air. The heat exchange structure is prior art and will not be described in detail here.

[0023] In addition to at least one air intake water deflector structure 20, the cabinet is provided with air intake 11. In this embodiment, there are three sets of air intake water deflectors, with a certain distance between adjacent sets to allow external air to enter. At the same time, the air intake water deflectors are arranged in an inclined installation manner to the horizontal plane, so that external air will be guided into the air intake 11 in the flow direction X.

[0024] A condensate tray 30 is installed at the bottom of the cabinet. The condensate tray 30 can collect condensate. The lowest point of the condensate tray 30 is connected to a drain pipe, which can drain the condensate accumulated in the condensate tray 30.

[0025] See also Figure 3 and Figure 4 The air intake and water baffle structure 20 includes side plates 21 connected to both sides of the air intake 11 of the cabinet, a water baffle 22 installed on the side plates 21, and a sealing plate 24.

[0026] Both the baffle plate 22 and the sealing plate 24 extend laterally along the air inlet 11. The baffle plate 22 includes an integrally bent baffle section 221, an upper extension section 222 and a lower extension section 223 connected to the upper and lower edges of the baffle section 221, and an installation section 224 connected to both sides of the baffle section 221. The installation section 224 is connected to the side plate 21 by fasteners.

[0027] A groove 225 is formed on the end face of the water-blocking section 221 away from the air inlet 11. The groove 225 protrudes towards the air inlet 11, and a heating tube 23 is disposed within the groove 225. In this embodiment, the heating tube 23 is a coil, and the shape of the groove 225 matches the shape of the heating tube 23. After the heating tube 23 is installed behind the groove 225, it is further fixed by multiple tube clamps 25. Specifically, the tube clamps 25 have a clamping section that fits against the outer contour of the heating tube 23 and connecting sections extending outward from both sides of the clamping section. The two connecting sections are connected to the water-blocking section 221 by fasteners to fix the heating tube 23.

[0028] The sealing plate 24 also includes an integrally bent sealing section 241 and a limiting section 242 extending outward from one side of the sealing section 241. The sealing plate 24 is connected to the side of the baffle plate 22 near the heating pipe 23. The sealing plate 24 and the baffle plate 22 are separately set. After they abut against each other, there is a certain gap between the sealing section 241 and the baffle section 221 to form a heating chamber 26. The heating pipe 23 extends out from the groove 225. The limiting section 242 abuts against the end face of the upper extension section 222. One end of the sealing section 241 abuts against the end face of the lower extension section 223. The heating chamber 26 is closed by the two side plates 21.

[0029] Combination Figure 5The side plate 21 has a sliding opening 211, the width of which is slightly larger than the thickness of the closed section 241, allowing the closed section 241 to slide smoothly into the sliding opening 211. The side plate 21 also has a limiting opening 212 connecting to the sliding opening 211, with the limiting section 242 engaging in the limiting opening 212. Because the closed section 241 is inclined, it can quickly slide into the sliding opening 211 under its own weight until the limiting section 242 is engaged in the limiting opening 212. The corresponding water-blocking section 221 is also arranged in an inclined manner, allowing condensed water droplets to slide down along the inclined direction Y and fall into the water receiving tray 30.

[0030] In another embodiment, the sealing plate 24 is also connected to the side plate 21 by fasteners, or by other detachable means. This detachable structure facilitates subsequent maintenance of the heating element 23.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
