Description

A wind wall

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on January 24, 2024, with application number 202410102490.X and invention name “A Wind Wall”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present invention relates to the technical field of air cooling, and more particularly to a wind wall. Background Art

[0003] Air wall air conditioners offer the advantages of high air volume and cooling capacity. Their use in server rooms allows them to achieve higher heat flux density loads. However, while cooling the servers, the heat-generating components within the air wall itself are also important. If the temperature rise of these components during operation cannot be promptly controlled and resolved, the high operating temperatures can damage the components, compromising the reliability of the air conditioner. Therefore, research into the layout of these components within the air wall air conditioner is crucial.

[0004] Currently, more heat dissipation designs consider the targeted and separate setting of air cooling or water cooling. Although this can solve the heat dissipation problem, the additional components will undoubtedly make the equipment more powerful and more expensive. At the same time, new components that may fail will be added, reducing the operating reliability of the unit.

[0005] During the process of implementing the present invention, the inventors discovered that the prior art has at least the following problems: at least part of the electrical devices has difficulty in dissipating heat.

[0006] Summary of the Invention

[0007] In view of this, an object of the present invention is to provide a wind wall, which can effectively solve the problem of inconvenient heat dissipation of at least some electrical devices.

[0008] In order to achieve the above object, the present invention provides the following technical solutions:

[0009] A wind wall includes a fan assembly and an electrical device, at least one of the electrical devices is a front heat dissipation box arranged on one side of the air inlet of the fan assembly, the front heat dissipation box is provided with a power-consuming element that generates heat in a working state, and the front heat dissipation box is provided with a first opening and a second opening that pass through each other inside the box cavity. In the direction of the air inlet of the fan assembly, the first opening is closer to the air inlet than the second opening.

[0010] When the above-mentioned wind wall is applied, in the working state, the fan assembly is generally turned on accordingly. When the fan assembly is turned on, the air inlet of the fan assembly forms a strong suction force. Since the front heat dissipation box is arranged on the air inlet side, and the first opening on the front heat dissipation box is closer to the air inlet than the second opening, under the suction action of the air inlet of the fan assembly, the wind in the front heat dissipation box flows from the second opening to the first opening, and when flowing through the power-consuming components, it can absorb heat and then flow out from the first opening, and the second opening can be supplemented with fresh air from the outside to allow the power-consuming components to continuously absorb heat, thereby achieving heat dissipation of the power-consuming components. In the aforementioned wind wall, the front heat sink is positioned at the air inlet, and has corresponding first and second openings. The first opening is closer to the air inlet than the second opening, so that the strong suction force of the air inlet can be used to promote air flow within the front heat sink. External air can also be added to achieve air cooling of the electrical components within the front heat sink without the need for a separate fan. Furthermore, the air volume required for heat dissipation by the front heat sink is much smaller than the air volume generated by the fan assembly, thereby not affecting the operating efficiency of the fan assembly. In summary, the wind wall can effectively solve the problem of poor heat dissipation of at least some electrical components within the wind wall.

[0011] In some technical solutions, in the direction of the air inlet of the fan assembly, the first opening and the second opening are respectively formed at two ends of the front heat dissipation box that are away from each other.

[0012] In some technical solutions, the front heat dissipation box is arranged on the outside of the area where the air inlet of the fan assembly extends in the opposite direction of the air inlet.

[0013] In some technical solutions, an air guide surface is provided between the first opening and the air inlet of the fan assembly to guide the airflow of the first opening to the air inlet of the fan assembly.

[0014] In some technical solutions, a wind guide plate is also included, and one side of the wind guide plate is a wind guide surface; one side edge of the wind guide surface is connected to the side edge of the first opening away from the air inlet, and the other side edge is inclined in the direction away from the first opening and extends toward the air inlet.

[0015] In some technical solutions, a heat exchange component is included, at least one of the fan components is a centrifugal fan component, and the heat exchange component and the centrifugal fan component are arranged side by side along the air outlet direction; an air cavity is formed between the heat exchange component and the centrifugal fan component so that the air outlet of the centrifugal fan component is evenly blown toward the heat exchange component.

[0016] In some technical solutions, at least one of the electrical devices is a rear electrical device arranged in the wind cavity, and at least part of the wind thrown out from the air outlet of the centrifugal fan assembly can pass through the rear electrical device.

[0017] In some technical solutions, a fan mounting portion is further included, on which an inspection opening is provided that matches the size of at least one of the rear electrical components; a slide rail is provided at the bottom of the rear electrical component so that when the inspection opening is opened, the rear electrical component can slide out from the inspection opening.

[0018] In some technical solutions, at least one of the front heat dissipation boxes is an electric control box and / or at least one of the front heat dissipation boxes is an electrical component box.

[0019] In some technical solutions, a frame is included, the fan mounting portion is perpendicular to the air inlet direction of the fan assembly and is upright in the frame, at least one electrical control box is installed on a lateral side panel of the frame; at least one electrical component box is detachably installed on the lower side panel of the frame.

[0028] An embodiment of the present invention discloses a wind wall to effectively solve the problem of inconvenient heat dissipation of at least some electrical devices.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Please refer to Figures 1-2, Figure 1 is a structural diagram of a wind wall provided by an embodiment of the present invention; Figure 2 is a side structural diagram of a wind wall provided by an embodiment of the present invention.

[0031] In some embodiments, a wind wall is provided. Specifically, the wind wall primarily includes a fan assembly 1 and an electrical device 2. A base is generally provided to mount the fan assembly 1 and the electrical device 2 to form an integrated wind wall. The fan assembly 1 is generally used to introduce external air to a heat exchange assembly 3 or other components in an air conditioning system that require air cooling.

[0032] At least one electrical device 2 is a front heat sink disposed on one side of the air inlet 1-2 of the fan assembly 1. This means the front heat sink is located on the air inlet 1-2 side of the fan assembly 1, i.e., within the wind pressure region of the air inlet 1-2. The fan assembly 1 has an air inlet 1-2 and an air outlet. The fan assembly 1 is configured to pressurize air at the air inlet 1-2 and push it out of the outlet. Generally, the air inlet 1-2 is at a low pressure, allowing the outside world to continuously supply air to the air inlet 1-2.

[0033] The at least one electrical device 2 is intended to indicate that the wind wall may have only one electrical device 2, in which case this electrical device 2 is the front heat sink. Alternatively, multiple electrical devices 2 may be provided, and when multiple electrical devices 2 are provided, different electrical devices 2 may be installed in different ways, in which case at least one of the electrical devices 2 is the front heat sink. Alternatively, multiple or all electrical devices 2 may be front heat sinks. The term "front" in the term "front heat sink" is not intended to limit the connection relationship or structural shape, but is simply used for the convenience of description.

[0034] The front heat sink box houses power-consuming components that generate heat during operation. This requires a cavity, which can be formed around the substrate and other components of the power-consuming components, or it can be a separate housing. The power-consuming components are located within the cavity to exchange heat with the air within, thereby dissipating heat. While the power-consuming components generate heat during operation, this does not necessarily mean they are always generating heat, but rather that they generate heat during at least one operating state.

[0035] The front heat sink has a first opening 2-1 and a second opening 2-2 that extend through the interior of the housing. "Internal connection" means that air can enter through one opening and exit through the other. For example, after air enters the housing through the second opening 2-2, it can absorb heat from heat-generating electrical components within the housing before exiting through the first opening 2-1. This means that when the wind pressures at the first opening 2-1 and the second opening 2-2 differ, air can flow through the interior.

[0036] In the direction of the air inlet 1-2 of the fan assembly 1, the first opening 2-1 is closer to the air inlet 1-2 than the second opening 2-2. When the fan assembly 1 is turned on, the wind at the air inlet 1-2 flows toward the air inlet 1-2. Since the first opening 2-1 is closer to the air inlet 1-2 than the second opening 2-2, the wind between the first opening 2-1 and the second opening 2-2 will flow from the second opening 2-2 to the first opening 2-1. Since the second opening 2-2 exists, the second opening 2-2 can introduce wind from the outside, and then the wind passes through the box cavity and flows out from the first opening 2-1 to guide the air inlet 1-2 of the fan assembly 1. It should be noted that whether the first opening 2-1 is closer to the air inlet 1-2 than the second opening 2-2 can be determined by determining whether, when the fan assembly 1 is turned on, the air flows from the second opening 2-2 to the first opening 2-1 or from the first opening 2-1 to the second opening 2-2. The former indicates that the first opening 2-1 is closer to the air inlet 1-2 than the second opening 2-2. There are at least two ways to determine this: one method can be based on the air inlet direction of the fan assembly 1; the other method can be based on a direction perpendicular to the air inlet direction of the fan assembly 1.

[0037] In some embodiments, when the above-mentioned wind wall is applied, in the working state, the fan assembly 1 is generally turned on accordingly, and when the fan assembly 1 is turned on, the air inlet 1-2 of the fan assembly 1 forms a strong suction force. Since the front heat dissipation box is arranged on the side of the air inlet 1-2, and the first opening 2-1 on the front heat dissipation box is closer to the air inlet 1-2 than the second opening 2-2, the wind in the front heat dissipation box flows from the second opening 2-2 to the first opening 2-1 under the suction action of the air inlet 1-2 of the fan assembly 1, and when flowing through the power-consuming components, it can absorb heat and then flow out from the first opening 2-1, and the second opening 2-2 can be supplemented with fresh air from the outside to continuously absorb heat from the power-consuming components, thereby achieving heat dissipation of the power-consuming components. In the above-mentioned wind wall, the front heat dissipation box is arranged at the air inlet 1-2, and a first opening 2-1 and a second opening 2-2 are correspondingly provided. The first opening 2-1 is closer to the air inlet 1-2 than the second opening 2-2, so that the strong suction force of the air inlet 1-2 can be used to promote the flow of air inside the front heat dissipation box, and air can be added from the outside to achieve air cooling of the power-consuming components in the front heat dissipation box without the need for a separate fan. Moreover, the air volume required for heat dissipation by the front heat dissipation box is much smaller than the air volume generated by the fan assembly 1, thereby not affecting the working efficiency of the fan assembly 1. In summary, the wind wall can effectively solve the problem of poor heat dissipation effect of at least some power-consuming components in the wind wall.

[0038] In some embodiments, in order to better promote the circulation of air inside the front heat dissipation box, it is preferred here that a first opening 2-1 and a second opening 2-2 are respectively provided at two ends of the front heat dissipation box that are away from each other in the direction of the air inlet 1-2 of the fan assembly 1, that is, in the direction of the air inlet 1-2 of the fan assembly 1, the first opening 2-1 is closer to the air inlet 1-2 than the second opening 2-2.

[0039] Of course, the first opening 2-1 and the second opening 2-2 may be respectively provided at two ends of the front heat dissipation box that are away from each other in the direction perpendicular to the direction of the air inlet 1-2 of the fan assembly 1, so as to utilize the radial wind pressure change.

[0040] In some embodiments, it is preferred that the front heat dissipation box is disposed outside the area extending in the opposite direction of the air inlet of the fan assembly 1, including the first opening 2-1 and the second opening 2-2, both of which are disposed outside the area extending in the opposite direction of the air inlet of the fan assembly 1, so as to avoid the front heat dissipation box from blocking or interfering with the main air inlet area of ​​the air inlet 1-2 of the fan assembly 1. It should be noted that the area extending in the opposite direction of the air inlet of the fan assembly 1 refers to the area through which the air inlet 1-2 passes in a radial manner in the opposite direction of the air inlet. This is because the wind entering the air inlet 1-2 all enters the air inlet 1-2 from this area.

[0041] The front heat dissipation box is arranged on the outside of the area where the air inlet 1-2 of the fan assembly 1 extends in the opposite direction of the air inlet. From another perspective, in the vertical direction of the direction of the air inlet 1-2 of the fan assembly 1, the distance between each part of the front heat dissipation box and the central axis of the air inlet 1-2 is greater than the distance between the edge of the air inlet 1-2 and the center line of the air inlet 1-2.

[0042] In some embodiments, an air guide surface can be provided between the first opening 2-1 and the air inlet 1-2 of the fan assembly 1 to guide the airflow of the first opening 2-1 to the air inlet 1-2 of the fan assembly 1, so that the wind flowing out of the first opening 2-1 can be guided to the air inlet 1-2 of the fan assembly 1 as quickly as possible, and can be guided to the air inlet 1-2 of the fan assembly 1 more smoothly, so as to effectively ensure the air flow rate in the front heat dissipation box, and thus effectively ensure the heat dissipation efficiency.

[0043] It should be noted that the wind guide surface can be provided on the base, a side surface of the block, or a side surface of the plate. For ease of arrangement, a wind guide plate 5 is preferably further provided, with one side surface of the wind guide plate 5 serving as the wind guide surface, and one side surface of the wind guide plate 5 faces the first opening 2-1.

[0044] In some embodiments, to better guide air, one edge of the air guide surface is preferably connected to the edge of the first opening 2-1 away from the air inlet 1-2, while the other edge is inclined away from the first opening 2-1 and extends toward the air inlet 1-2. That is, the air guide surface is tilted relative to the direction of the air inlet 1-2, and the air guide surface is tilted toward the air outlet to better guide air to the air inlet 1-2 of the fan assembly 1. It should be noted that the air guide surface can be flat or curved, and can be specifically configured as needed to guide air toward the air inlet 1-2.

[0045] In some embodiments, at least one front heat dissipation box is an electrical control box 2-3, with a first opening 2-1 and a second opening 2-2 respectively opened at both ends of the electrical control box 2-3, so that under the action of the fan assembly 1, the wind enters through the second opening 2-2, dissipates the heat of the internal control element (a type of power-consuming element), and then flows out from the first opening 2-1.

[0046] In some embodiments, at least one front heat dissipation box is an electrical device box 2-4, so as to dissipate heat through the electrical devices inside the electrical device box 2-4. Specifically, at least one of the front heat dissipation boxes is an electric control box 2-3 and / or at least one front heat dissipation box is an electrical device box 2-4.

[0047] In some embodiments, a heat exchange assembly 3 may be further disposed within the wind wall. This heat exchange assembly 3 is typically a heat exchange coil, but other heat exchange assemblies 3 may also be employed. Air flowing perpendicular to the panel surface passes through the heat exchange assembly 3 to exchange heat with the heat exchange assembly 3. Generally, the air flow can be evenly distributed along the panel surface and pass through the heat exchange assembly 3 evenly. If the wind wall serves as a condenser, the heat exchange assembly 3 may be a condensing plate; if the wind wall serves as an evaporator, the heat exchange assembly 3 may be an evaporating plate.

[0048] In some embodiments, at least one fan assembly 1 can be a centrifugal fan assembly, that is, the fan has a centrifugal structure, and the airflow is centrifugally ejected by the fan. The heat exchange assembly 3 and the centrifugal fan assembly are arranged side by side along the air outlet direction, and the plate thickness direction of the heat exchange assembly 3 is consistent with the above-mentioned parallel direction. An air cavity 4 is formed between the heat exchange assembly 3 and the centrifugal fan assembly so that the air discharged from the centrifugal fan assembly outlet is evenly blown toward the heat exchange assembly 3. In actual applications, the ideal air supply distance of the fan assembly 1 can be achieved by controlling the distance between the heat exchange assembly 3 and the centrifugal fan, so as to ensure that the air body ejected by the centrifugal fan assembly enters the air cavity 4, is collected in the closed air cavity 4, and then evenly passes through the heat exchange assembly 3 for heat exchange and cooling, so as to avoid the occurrence of excessively high local wind speeds in the windward area of ​​the heat exchange assembly 3. At this time, the airflow organization can pass through the entire windward plate surface of the heat exchange assembly 3 more evenly, so that the heat exchange assembly 3 can more fully exchange heat and achieve the best performance of the unit.

[0049] In some embodiments, at least one electrical device 2 is a rear electrical device 2-5 disposed within the air cavity 4. At least a portion of the air ejected from the centrifugal fan assembly's air outlet passes through the rear electrical device 2-5. Generally, the rear electrical devices 2-5 require less maintenance than the electrical devices in the front heat sink. Therefore, disposing them within the air cavity 4 can meet usage requirements.

[0050] In some embodiments, further, to facilitate maintenance of the rear electrical components 2-5, a fan mounting portion 1-1 is preferably included. The fan mounting portion 1-1 is provided with an inspection port 1-3 that matches the size of at least one rear electrical component 2-5, and a slide rail 6 is provided at the bottom of the rear electrical component 2-5 so that when the inspection port 1-3 is opened, the rear electrical component 2-5 can slide out of the inspection port 1-3. Specifically, the direction of the inspection port 1-3 is preferably opposite to the air inlet direction of the fan assembly 1. When maintenance is required, the inspection port 1-3 can be opened, and due to the restraining effect of the slide rail 6, only the rear electrical component 2-5 needs to be pulled out.

[0051] In some embodiments, a frame 7 is preferably also included here to serve as the above-mentioned base, and the fan mounting portion 1-1 therein is perpendicular to the air inlet direction of the fan assembly 1 and is upright in the frame 7. The middle part of the fan mounting portion 1-1 is opened to place the fan of the fan assembly 1, and the wind body of the fan assembly 1 is generally cylindrical.

[0052] At least one front heat dissipation box can be mounted on a lateral side panel of the frame 7, such as the electric control box 2-3; at least one electrical component box 2-4 can be detachably mounted on the lower side panel of the frame 7, and the air guide plate 5 at the first opening 2-1 of the electrical component box 2-4 blocks the inspection port 1-3. Of course, the inspection port 1-3 can be further provided with a separate door. During use, when it is necessary to repair the above-mentioned rear electrical components 2-5, the above-mentioned electrical component box 2-4 and the corresponding air guide plate 5 can be first removed to expose the inspection port 1-3, and then the rear electrical components 2-5 can be pulled out through the inspection port 1-3 for repair or removed for repair. Alternatively, the air guide plate 5 can also be left unblocked on the inspection port 1-3. In this case, it is only necessary to stagger the electrical component box 2-4 and the rear electrical components 2-5.

[0053] As shown in the attached drawings, two fan assemblies 1 are arranged horizontally side by side, and the above-mentioned electrical control box 2-3 is provided on the side of at least one fan assembly 1 away from the other fan assembly 1. The fan mounting portion 1-1 is arranged perpendicular to the air inlet direction, and the inspection port 1-3 is arranged through along the air inlet direction. One side is provided with a rear electrical device 2-5, and the other side is provided with an electrical device box 2-4. It should be noted that the power-consuming components of the rear electrical device 2-5 can be exposed in the wind cavity 4. Of course, a compressor 8 can also be provided on the air inlet side, and the compressor 8 is arranged between the two fan assemblies 1, so that the compressor 8 will not block the wind from the air inlets of the two fan assemblies 1.

[0054] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0055] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
