Abstract
Description
Technical Field
[0001] The utility model relates to the field of data centers, and more specifically, to a centrifugal fan for a data center. Background Art
[0002] A data center is a physical location for storing computers and their related hardware devices, and is a physical room, building or facility that houses the IT infrastructure. It includes the computing infrastructure required by the IT system, such as servers, data storage drives, and network devices. Therefore, since there are many servers inside the data center, and the servers will generate heat during use, resulting in a relatively high temperature inside the entire data center, and the high temperature will affect the normal use of the servers.
[0003] Therefore, it is necessary to cool down the data center to improve the internal heat dissipation effect and ensure the normal operation of the servers. In the air conditioning system of the data center, a corresponding centrifugal fan is used to improve the air flow. The traditional centrifugal fan rotates the impeller through an electric motor to achieve its operation. However, in order to ensure the stability of the fan, the air outlet of the fan often adopts a fixed structure, that is, the relative position of the air outlet and the entire fan device is fixed. This leads to the need to adjust the entire device if the air outlet position needs to be adjusted, which is extremely inconvenient. The ventilation ducts in the data center are laid according to the size of the data center, so the positions of the ventilation ducts are also not fixed. Therefore, the fixed air outlet of the centrifugal fan has insufficient flexibility in use. Summary of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0022] Embodiment:
[0023] Please refer to Figure 1 and Figure 2 As shown, a centrifugal fan for a data center includes a base 1, a coupling 3, and a fan housing 5. A drive motor 2 is fixed on one side of the top of the base 1, and a support platform 4 is fixedly installed on the other side of the top of the base 1. The support platform 4 and the base 1 are fixed by bolts. The fan housing 5 is placed above the support platform 4. An impeller 51 is rotatably installed inside the fan housing 5. The rear end of the impeller 51 is power-connected to the output end of the drive motor 2 through the coupling 3. An air inlet 52 is provided on the side of the fan housing 5 facing away from the drive motor 2, and an air outlet 53 is provided on one side of the surface of the fan housing 5, so as to control the impeller 51 inside the fan housing 5 to rotate through the drive motor 2, so as to inhale gas through the air inlet 52 at the front end and discharge it through the air outlet 53 on one side.
[0024] Please refer to Figures 1-4As shown, a support plate A42 is vertically arranged on the front side of the upper surface of the support platform 4, and a support plate B43 is arranged on the rear side of the upper surface of the support platform 4, the support plate A42 and the support plate B43 are arranged in parallel, and the tops of the support plates A42 and B43 are both provided with arc-shaped concave surfaces, and the arc-shaped concave surfaces are adapted to the curvature of the surface of the fan housing 5, the fan housing 5 is placed above the support plates A42 and B43, and supported by the support plates A42 and B43 to ensure the stability of the fan housing 5, and the outer surface of the fan housing 5 is symmetrically provided with clamping strips 56, and the arc surfaces of the support plates A42 and B43 are both provided with grooves 44, and the clamping strips 56 slide inside the grooves 44 to prevent the fan housing 5 from axial movement after the initial installation. At this time, the fan housing 5 can only rotate to adjust the position of the air outlet 53. A convex strip 54 is welded on the outer surface of the fan housing 5. The convex strip 54 is placed between the two clamping strips 56. Positioning holes 55 are evenly opened on the surface of the convex strip 54 with the center of the fan housing 5 as the center of the circle. The convex strip 54 will rotate with the fan housing 5. Conversely, the fixing of the convex strip 54 can achieve the fixation of the fan housing 5. Slide rods 62 are slidably installed on both sides of the surface of the support plate A42. The slide rod 62 passes through the positioning hole 55. Through holes 45 corresponding to the ends of the slide rod 62 are opened on both sides of the surface of the support plate B43. When the air outlet angle is adjusted, the slide rod 62 is slid backward to pass through the corresponding positioning hole 55 and is fixed in cooperation with the through hole 45 on the rear side.
[0025] Please refer to Figures 2-4 As shown, a baffle 63 is provided on the surface of the slide rod 62, and the baffle 63 is placed between the convex strip 54 and the support plate A42. A spring 64 is sleeved on the surface of the slide rod 62, and the front end of the spring 64 contacts the surface of the support plate A42, and the rear end of the spring 64 contacts the surface of the baffle 63. The elastic force of the spring 64 is used to make the baffle 63 always receive a backward force to ensure the stability of the fixation of the fan housing 5, wherein the baffle 63 can increase the fulcrum of the rear end of the spring 64, and when the slide rod 62 moves forward during installation, it will not affect the installation of the fan housing 5.
[0026] Among them, a track 41 is symmetrically arranged on the front side of the upper surface of the support platform 4, and the cross-section of the track 41 is T-shaped. A slide seat 6 is slidably installed on the surface of the track 41. The track 41 can ensure the stability of the movement of the slide seat 6, so that the slide seat 6 and the slide rod 62 can only move forward and backward. A vertical plate 61 is vertically arranged on the upper surface of the slide seat 6, and the slide rod 62 penetrates the support plate A42. The front end of the slide rod 62 is fixed on the top of the vertical plate 61, and a connecting rod 7 is horizontally installed between the two slide seats 6. The connecting rod 7 is placed under the fan housing 5 so that the connecting rod 7 can be placed under the fan housing 5.
[0027] Working principle: During installation, first fix the base 1 on the ground surface, and keep the top drive motor 2 and the support platform 4 fixed to the base 1 by bolts. Then place the fan housing 5 above the support plate A42 and the support plate B43, with the air inlet 52 facing forward. At the same time, place the clamping strip 56 inside the groove 44 for step-by-step fixation. At this time, the impeller 51 is at the same height as the center line of the drive motor 2. At this time, the impeller 51 can be controlled through the coupling 3, and the fan housing 5 can rotate. During the rotation process, the convex strip 54 on its surface can rotate together with the fan housing 5. Due to the existence of the spring 64, the baffle 63 is always subjected to a backward force. During installation, pull the connecting rod 7 outward to control the sliding seats 6 on both sides to move forward, so that the sliding rod 62 moves forward, causing the spring 64 to be squeezed and store energy. Pull outward so that the rear end of the sliding rod 62 is placed in front of the convex strip 54, so that the fan housing 5 can be smoothly installed in place. After adjusting the direction of the air outlet 53, the sliding rod 62 can pass through the positioning hole 55 at the corresponding position and cooperate with the through hole 45 to fix the fan housing 5.
[0028] The above is only the preferred specific implementation mode of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
