Description

Technical Field

[0001] This invention relates to the field of cooling unit technology, and in particular to a descaling structure and an evaporative cooler unit. Background Technology

[0002] Evaporative cooler units are mainly used for environmental temperature control in data center computer rooms. They primarily consist of a casing, spray system, condenser, water collection tank, indoor fan, outdoor fan, and compressor refrigeration system. The spray system, water collection tank, and condenser are all housed within the casing. The spray system sprays liquid onto the condenser to achieve heat exchange and cooling. The water collection tank is located below the condenser to collect the liquid sprayed by the spray system.

[0003] Because the liquid contains calcium, magnesium, and other minerals, scale will form on the coils of the evaporative cooler unit after long-term use, which will reduce the heat dissipation efficiency of the condenser.

[0004] Therefore, how to remove scale from condensers is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the first objective of the present invention is to provide a descaling structure capable of removing scale from condensers.

[0006] A second objective of this invention is to provide an evaporative cooler unit.

[0009] The transducer head is installed inside the housing, and the vibration direction of the transducer head is parallel to the flow direction of the liquid sprayed onto the transducer head, so as to cavitate the liquid and remove scale from the condenser inside the housing.

[0010] In one specific implementation, the transducer head is positioned below the condenser and above the water collection tank of the evaporative cooler unit, the water collection tank being placed inside the outer casing and positioned below the condenser;

[0011] and / or

[0012] The transducer head is positioned above the condenser and below the spray device of the evaporative cooler unit. The spray device is located inside the outer casing and above the condenser.

[0013] and / or

[0014] The transducer head is placed in the gap between adjacent coils of the condenser.

[0015] and / or

[0016] The transducer head is installed at the outlet of the spray head of the spray device of the evaporative cooler unit;

[0017] and / or

[0018] The transducer head is placed inside the water collection tank.

[0019] In another specific implementation, the transducer head includes a transducer plate with multiple drainage holes.

[0020] In another specific embodiment, the transducer head further includes a plurality of protrusions disposed on the transducer plate, the protrusions being disposed on the end face of the transducer plate opposite to the flow direction of the liquid;

[0021] and / or

[0022] The transducer plate has multiple recesses, which are formed on the end face of the transducer plate opposite to the flow direction of the liquid.

[0023] In another specific embodiment, the protrusion is located directly below the flow channel of the liquid, and each protrusion corresponds to at least one flow channel;

[0024] and / or

[0025] The pit is located directly below the flow channel of the liquid, and each pit corresponds to at least one flow channel.

[0026] In another specific implementation, the protrusion includes a support rod and a ball;

[0027] The first end of the support rod is connected to the transducer plate, and the second end of the support rod is connected to the sphere.

[0028] In another specific embodiment, a rotating shaft is fixed to each side of the transducer plate, and the rotating shaft is rotatably mounted on the outer casing;

[0029] The transducer plate can be rotated to be perpendicular or parallel to the spray direction of the spray device of the evaporative cooler unit.

[0030] In another specific embodiment, the descaling structure further includes a locking device mounted on the housing for limiting the rotation of the shaft.

[0031] In another specific implementation, the locking device includes a telescopic rod and a telescopic drive member;

[0032] The rotating shaft has an insertion hole for inserting into the telescopic rod. The fixing part of the telescopic drive is fixed to the outer shell. The driving part of the telescopic drive is connected to the telescopic rod and is used to drive the telescopic rod to be inserted into or moved out of the insertion hole.

[0033] In another specific embodiment, the descaling structure further includes a rotary drive and a transmission assembly;

[0034] The output end of the rotary drive is connected to the input end of the transmission assembly, and the output end of the transmission assembly is transmissively connected to the rotating shaft.

[0039] The descaling structure disclosed in this invention involves installing a transducer head inside a housing and aligning the vibration direction of the transducer head with the flow direction of the liquid sprayed onto the transducer head. When the ultrasonic generator is activated, the liquid collides with the transducer head, cavitation generates tiny shock waves, and these shock waves break up the scale on the condenser, causing the scale to detach from the condenser.

[0040] Furthermore, since the vibration direction of the transducer head is parallel to the flow direction of the liquid sprayed onto the transducer head, the radial component in the direction perpendicular to the liquid flow is reduced by utilizing the directionality of the liquid, thus reducing energy loss. With the help of the continuity of liquid molecules, the energy is transmitted to a greater distance, thereby maximizing the effect of the transducer head vibration transmission collision.

Detailed Implementation

[0058] The following will refer to the appendices in the embodiments of the present invention. Figures 1-10 The technical solutions in the embodiments of the present invention will be clearly and completely described. The present invention can be implemented in many different forms and is not limited to the implementation methods described in this embodiment. The purpose of providing the following specific embodiments is to facilitate a clearer and more thorough understanding of the disclosure of the present invention, wherein the words indicating directions below refer only to the position of the shown structure in the corresponding drawings.

[0059] It is understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. When used herein, the singular forms “a” and “” are intended to include the plural forms as well, unless the context clearly indicates otherwise. Furthermore, when used in this specification, the terms “comprising” and / or “including” indicate the presence of features, integrals, steps, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, elements, components, and / or combinations thereof. The following description is a preferred embodiment for carrying out the invention; however, the description is for the purpose of illustrating the general principles of the invention and is not intended to limit the scope of the invention. The scope of protection of this invention is determined by the appended claims.

[0060] like Figures 1-7 As shown, the present invention provides a descaling structure 100, applied to an evaporative cooler unit 1000. The evaporative cooler unit 1000 includes a housing 200 and a condenser 300, the condenser 300 being housed within the housing 200, as shown... Figures 8-10 As shown.

[0061] The descaling structure 100 includes an ultrasonic generator 101 and a transducer head 102, with the ultrasonic generator 101 electrically connected to the transducer head 102. The ultrasonic generator 101 is disposed outside the housing 200.

[0062] The transducer head 102 is installed inside the housing 200, and the vibration direction of the transducer head 102 is parallel to the flow direction of the liquid sprayed onto the transducer head 102, so as to remove scale from the condenser 300 inside the housing 200 by cavitation liquid. Specifically, the vibration direction of the transducer head 102 is along the forward or reverse direction of the liquid.

[0063] It should be noted that the liquid can be the liquid sprayed by the spray device 500 above the condenser 300, or the liquid sprayed by a separate external water pipe, etc.

[0064] The descaling structure 100 disclosed in this invention is used by installing a transducer head 102 inside a housing 200, with the vibration direction of the transducer head 102 parallel to the flow direction of the liquid sprayed onto the transducer head 102. The ultrasonic generator 101 is then activated, and the liquid collides with the transducer head 102, generating cavitation and producing tiny shock waves that break up the scale on the condenser 300, causing the scale to fall off the condenser 300.

[0065] Furthermore, since the vibration direction of the transducer head 102 is parallel to the flow direction of the liquid sprayed onto the transducer head 102, the radial component of the transducer head 102 in the direction perpendicular to the liquid flow is reduced by utilizing the directionality of the liquid, thus reducing energy loss. With the help of the continuity of liquid molecules, the energy is transmitted to a greater distance to the maximum extent, thereby maximizing the effect of vibration transmission and collision of the transducer head 102.

[0066] In some embodiments, the transducer head 102 is positioned below the condenser 300 and above the water collection tank 400 of the evaporative cooler unit 1000. The potential energy of the falling water collides with the transducer head 102, accelerating its flow and cavitation, generating small shock waves that break up and remove scale. The water collection tank 400 is located inside the housing 200 and below the condenser 300. Figure 8 As shown; and / or, the transducer head 102 is positioned above the condenser 300 and below the spray device 500 of the evaporative cooler unit 1000. The pressure of the liquid sprayed from the nozzles of the spray device 500 causes collisions between liquid molecules with the transducer head 102, accelerating its flow and cavitation, generating fine shock waves that break up and remove scale. These cavitation shock waves not only remove scale from the condenser 300 but also from the spray heads of the spray device 500. The spray device 500 is housed within the casing 200 and positioned above the condenser 300. Figure 9 As shown; and / or the transducer 102 is placed in the gap between adjacent coils of the condenser 300, such as Figure 10 As shown; and / or the transducer head 102 is placed in the water collection tank 400, such as Figure 10As shown; and / or the transducer head 102 is installed at the outlet of the spray head of the spray device 500 of the evaporative cooler unit 1000. The mechanical energy of the water pump of the spray device 500 is converted into the potential energy of the liquid, which is accelerated to collide with the transducer head 102, promotes cavitation, and generates fine shock waves to break up and remove the scale.

[0067] It should be noted that the arrangement of the transducer head 102 disclosed above is only one specific embodiment of the present invention. In practical applications, the transducer head 102 can also be set in other locations.

[0068] In some embodiments, such as Figure 1 As shown, the transducer head 102 includes a transducer plate 102a, which has multiple drainage holes 102a-1, allowing liquid flow to pass through the drainage holes 102a-1 and enter the water collection tank 400 below.

[0069] It should be noted that the transducer plate 102a is a one-piece molded plate, and its shape is not limited. It can be a regular shape plate such as a square plate or a round plate, or an irregular shape plate such as an irregular shape plate, depending on the specific needs.

[0070] Furthermore, such as Figure 2 and Figure 3 As shown, the present invention discloses that the transducer head 102 further includes a plurality of protrusions 102a-2 disposed on the transducer plate 102a, the protrusions 102a-2 being disposed on the end face of the transducer plate 102a opposite to the flow direction of the liquid. The protrusions 102a-2 can cause the liquid to rebound or bounce, further increasing the impact force on the liquid and enhancing the energy of the shock wave generated after liquid cavitation.

[0071] Furthermore, the present invention discloses that the protrusion 102a-2 is located directly below the liquid flow channel 501, which further improves the impact force generated by the protrusion 102a-2 on the liquid. Specifically, each protrusion 102a-2 corresponds to at least one flow channel 501, and the protrusion 102a-2 and the flow channel 501 correspond one-to-one, or each protrusion 102a-2 corresponds to two or more flow channels 501.

[0072] It should be noted that flow channel 501 refers to the liquid flow channel on which the liquid is sprayed onto the transducer plate 102a. Taking the liquid sprayed by the spray device 500 as an example, flow channel 501 refers to the liquid flow sprayed by each spray head on the spray device 500. When the liquid is sprayed from the pipe, flow channel 501 refers to the liquid flow sprayed from the outlet of the pipe onto the transducer plate 102a.

[0073] Furthermore, such as Figure 3As shown, the present invention discloses that the protrusion 102a-2 includes a support rod 102a-2a and a sphere 102a-2b. The first end of the support rod 102a-2a is connected to the transducer plate 102a, and the second end of the support rod 102a-2a is connected to the sphere 102a-2b.

[0074] Specifically, the support rod 102a-2a and the sphere 102a-2b are integrally formed and connected or welded together. The specific connection method is not limited. The sphere 102a-2b can be a hollow sphere or a solid sphere. The diameter of the support rod 102a-2a is smaller than the diameter of the sphere 102a-2b to facilitate vibration of the sphere 102a-2b. It is understood that the above structure of the protrusion 102a-2 is only one specific embodiment of the present invention. In practical applications, the protrusion 102a-2 can also be a cylindrical protrusion 102a-2, an arc protrusion 102a-2, or a conical protrusion 102a-2, etc.

[0075] In some embodiments, such as Figure 4 and Figure 5 As shown, multiple recesses 102a-3 are formed on the transducer plate 102a, and the recesses 102a-3 are formed on the end face of the transducer plate 102a opposite to the flow direction of the liquid. It should be noted that the recesses 102a-3 or the protrusions 102a-2 can be formed on the transducer plate 102a alone, or the recesses 102a-3 can be formed on the transducer plate 102a simultaneously.

[0076] The design of the pit 102a-3 enables the energy of the flowing liquid to be concentrated and reflected, thereby increasing the impact force on the liquid and enhancing the energy of the shock wave generated after liquid cavitation.

[0077] Specifically, the shape of the pit 102a-3 is not limited; it can be an arc-shaped pit 102a-3 or a square pit 102a-3, etc.

[0078] Furthermore, the present invention discloses that the recess 102a-3 is located directly below the liquid flow channel 501, which further enhances the impact force generated by the recess 102a-3 on the liquid. Each recess 102a-3 corresponds to at least one flow channel 501, that is, there is a one-to-one correspondence between the recess 102a-3 and the flow channel 501, or each recess 102a-3 corresponds to two or more flow channels 501.

[0079] It should be noted that the structure of the transducer head 102 disclosed above is only one specific embodiment of the present invention. In practical applications, the transducer head 102 may also include a base frame, which is a frame body welded from multiple rods, allowing liquid to pass through the gaps in the base frame into the water collection tank 400. Alternatively, the transducer head 102 may also include multiple branch rods, which are vertically welded to the base frame. Specifically, each branch rod corresponds to at least one flow channel 501.

[0080] In some embodiments, a rotating shaft is fixed on each side of the transducer plate 102a. The rotating shaft is rotatably mounted on the housing 200. The transducer plate 102a can be rotated by the rotating shaft to be perpendicular or parallel to the spray direction of the spray device 500 of the evaporative cooler unit 1000. This allows the transducer plate 102a to be placed vertically when descaling is not required, thus avoiding affecting the efficiency of the liquid entering the water collection tank 400 from the spray condenser 300.

[0081] Furthermore, the present invention discloses that the descaling structure 100 also includes a locking device installed on the housing 200, the locking device being used to restrict the rotation of the shaft so that the transducer plate 102a can be stably maintained in a certain state.

[0082] Specifically, the present invention discloses a locking device comprising a telescopic rod and a telescopic drive component. A connecting hole for insertion with the telescopic rod is provided on the rotating shaft. Specifically, there are two connecting holes, and the angle between the two connecting holes is 90°, to achieve switching between vertical and horizontal states of the transducer plate 102a. It should be noted that the number of connecting holes is not limited and can be increased or decreased as needed.

[0083] The fixing part of the telescopic drive component is fixed on the outer shell 200, and the driving part of the telescopic drive component is connected to the telescopic rod to drive the telescopic rod to be inserted into or moved out of the insertion hole.

[0084] Specifically, the telescopic drive component can be a pneumatic cylinder, a hydraulic cylinder, or an electric push rod, etc.

[0085] To facilitate the angle adjustment of the transducer plate 102a, the present invention discloses that the descaling structure 100 also includes a rotary drive and a transmission assembly.

[0086] The output end of the rotary drive is connected to the input end of the transmission assembly, and the output end of the transmission assembly is driveably connected to the rotating shaft. The transmission assembly is drively connected to the rotating shaft when the transducer plate 102a needs to be adjusted, and is disengaged from the rotating shaft when the transducer plate 102a does not need to be adjusted.

[0087] Specifically, the rotary drive component can be a motor or a rotary cylinder, etc.

[0088] The transmission component is a sprocket and chain or a gear and rack structure. When the transmission component is a sprocket and chain structure, a driving sprocket is installed at the driving end of the rotating drive component, and a driven sprocket is installed on the rotating shaft. The chain meshes with the driving sprocket and the driven sprocket respectively for transmission, and the chain is tensioned by a tension sprocket. The tension sprocket is movably mounted on the housing 200 by a cylinder, or it can be fixed to the housing 200 by screws.

[0089] In other embodiments, there are multiple transducers 102, which are spaced apart along the direction perpendicular to the liquid flow, such as... Figure 6 and Figure 7 As shown, multiple transducers 102 can be installed individually using a mounting bracket, or they can be fixed on the same mounting bracket.

[0090] Furthermore, the present invention discloses that the transducer head 102 is a cylindrical head or a square head. It is understood that the transducer head 102 being a cylindrical head or a square head is only one specific embodiment of the present invention. In practical applications, the transducer head 102 may also be configured as a conical head or other shapes.

[0091] Furthermore, the present invention discloses that the transducer head 102 is located directly below the liquid flow channel 501, and each transducer head 102 corresponds to at least one flow channel 501. That is, the transducer head 102 and the flow channel 501 are arranged in a one-to-one correspondence, or each transducer head 102 corresponds to at least two flow channels 501, which can be increased or decreased as needed.

[0092] like Figures 8-10 As shown, a second aspect of the present invention provides an indirect evaporative cooler unit 1000, including a housing 200, a condenser 300, a spray device 500, a water collection tank 400, and a descaling structure 100 as described in any of the above embodiments.

[0093] The condenser 300, spray device 500, water collection tank 400 and descaling structure 100 are all installed inside the outer casing 200, with the spray device 500 located above the condenser 300 and the water collection tank 400 located below the condenser 300.

[0094] Since the evaporative cooler unit 1000 provided by the present invention includes the descaling structure 100 in any of the above embodiments, the beneficial effects contained in the descaling structure 100 are all contained in the evaporative cooler unit 1000 disclosed by the present invention.

[0095] It should be noted that the directional terms used in this article, such as "up" and "down," are from the instructions attached. Figure 1 The direction setting is for ease of expression only and does not have any other specific meaning.

[0096] It should also be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that an article or apparatus comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such an article or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the article or apparatus that includes the aforementioned element.

The descriptions of the above embodiments are only for the purpose of helping to understand the core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
