Description

Technical Field

[0001] This utility model relates to the field of cabinet ventilation and heat dissipation technology, and in particular to a ventilation and heat dissipation cabinet. Background Technology

[0002] The primary purpose of ventilation and heat dissipation devices in outdoor server racks is to meet cooling needs. Electronic equipment installed inside outdoor racks generates a significant amount of heat during operation. If this heat cannot be dissipated in time, it can lead to overheating, affecting the equipment's performance and stability, and even causing hardware damage. Ventilation and heat dissipation devices effectively reduce the temperature inside the rack, ensuring the equipment operates within a suitable temperature range.

[0003] Chinese utility model patent CN206895043U discloses a perforated heat dissipation cabinet, including a cabinet body. The cabinet body includes a front panel, a rear cover, a top panel, a bottom panel, and two side panels. The front panel has a first louver group, which includes multiple first air outlet gaps and multiple first blades corresponding to the multiple first air outlet gaps. The multiple first blades are arranged in parallel and their outer ends are inclined downwards. The first blades can guide the air blown out of the first air outlet gaps downwards. The top panel has a second louver group, which includes multiple second air outlet gaps and multiple second blades corresponding to the multiple second air outlet gaps. The second blades are located above the second air outlet gaps and can guide the air blown out of the second air outlet gaps forward. When the equipment in the cabinet stops working, these fixed louvers on the cabinet cannot close themselves to protect the internal equipment, which poses a risk of equipment damage.

[0004] Therefore, existing technologies need to be improved and enhanced. Utility Model Content

[0005] The purpose of this utility model is to provide a ventilated heat dissipation cabinet to solve the technical problems existing in the prior art.

[0006] This utility model achieves the above objectives through the following technical means: A ventilation and heat dissipation cabinet includes a cabinet body. At least one rear door panel assembly is installed on the rear panel of the cabinet body. The rear door panel assembly includes at least one air outlet louver assembly. The air outlet louver assembly includes a louver frame and a plurality of louver blades. The louver frame is rotatably mounted with the plurality of louver blades in a vertical direction. The free ends of the upper louver blades rest on the side of the lower louver blades away from the airflow. Under the action of the airflow, the plurality of louver blades form an air outlet channel between adjacent louver blades. A Z-shaped baffle is provided on the bottom of the louver frame, which makes the lowermost louver blade cover at least half of the bottom area of ​​the louver frame.

[0007] As a further embodiment of this utility model, the cabinet body includes a front panel, a rear panel, a top panel, a bottom panel, and two side panels, with at least one of the rear door panel assemblies installed on the rear panel.

[0008] As a further embodiment of this utility model, the louver frame includes an upper baffle, a lower baffle, a left baffle, and a right baffle. The left baffle and the right baffle are each provided with a plurality of pivot holes, and the two ends of the plurality of louver blades are provided with pivots that are rotatably mounted in the pivot holes.

[0009] As a further embodiment of this utility model, the rear door panel assembly also includes a rear door panel located outside the air outlet louver assembly, and the rear door panel is provided with a plurality of ventilation and heat dissipation holes.

[0010] As a further embodiment of this utility model, the rear door panel assembly also includes a metal filter screen, which is located inside the air outlet louver assembly.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings: The embodiments described with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0018] In the description of this application, "several" or "more than" means two or more, unless otherwise explicitly specified.

Example

[0020] like Figure 1-4As shown, this application discloses a ventilation and heat dissipation cabinet, including a cabinet body 10. The cabinet body 10 includes a front panel, a rear panel, a top panel, a bottom panel, and two side panels. A rear door panel assembly 20 is installed on the rear panel of the cabinet body 10. The rear door panel assembly 20 includes an air outlet louver assembly 21. The air outlet louver assembly 21 includes a louver frame 211 and several louver blades 212. Several louver blades 212 are rotatably installed on the louver frame 211 in the vertical direction. The free ends of the upper louver blades rest on the side of the lower louver blades away from the airflow. Under the action of the airflow, the several louver blades 212 form an air outlet channel between adjacent louver blades 212. A Z-shaped baffle plate 213 is provided on the bottom of the louver frame 211, so that the lowermost louver blade covers half of the bottom area of ​​the louver frame. Through the above structural design, when the equipment is working, the air force generated by the equipment's built-in fan can effectively dissipate the heat. The multiple louvers of the louvered assembly create an air outlet channel between adjacent louvers. Heat generated during operation is dissipated through this channel for ventilation and heat dissipation. When the equipment stops, the fan ceases to generate airflow, and the louvers fall freely under gravity. The free ends of the upper louvers rest on the side of the lower louvers furthest from the airflow, achieving self-closing and protecting the internal equipment from damage. This balances the cabinet's ability to dissipate heat while maximizing protection for the internal equipment, achieving zero-energy operation. The Z-shaped baffle 213 covers half of the bottom area of ​​the louvered frame and also half of the bottom ventilation opening, allowing liquid entering the rear door assembly to flow out smoothly through the bottom ventilation opening, preventing water accumulation. Simultaneously, the bottommost louver is tilted, preventing all louvers from opening from the outside in, thus creating a seal and preventing foreign objects from entering.

[0021] Specifically, such as Figure 5-9 As shown, the louver frame 211 includes an upper baffle 2111, a lower baffle 2112, a left baffle 2113 and a right baffle 2114. The left baffle 2113 and the right baffle 2114 are each provided with a plurality of pivot holes, and both ends of the plurality of louver blades 212 are provided with pivots that are rotatably installed in the pivot holes.

[0022] Specifically, the rear door panel assembly 20 further includes a rear door panel 22, which is located outside the air outlet louver assembly 21. The rear door panel 22 is provided with a plurality of ventilation and heat dissipation holes. The air outlet louver assembly 21 is tightly attached to the inner side of the rear door panel 22 and then assembled onto the riveting screws of the rear door panel by nuts. The rear door panel assembly 20 also includes a metal filter 23, which is located inside the air outlet louver assembly 21. The metal filter is fixed to the louver frame of the air outlet louver assembly by screw fasteners or welding.

[0023] Specifically, such as Figure 11 As shown, an air guide hood 11 is provided inside the cabinet body 10 near the air outlet louver assembly 21. In specific implementation, the air guide hood is located between the equipment and the rear door panel assembly. The end of the air guide hood 11 away from the air outlet louver assembly 21 is a flared mouth, which is installed in close contact with the rear surface of the equipment by screw fasteners at the air outlet of the equipment to gather and guide the air outlet of the equipment, preventing backflow and crossflow. The opening size of the other end is slightly larger than the louver frame size of the air outlet louver assembly. Finally, it is installed in close contact with the rear end face and the inner side of the rear door to form a closed space.

[0024] Specifically, such as Figure 1 As shown, a partition 12 is provided inside the cabinet body 10, thereby dividing the cabinet body into two independent spaces; after the cabinet door is closed, the front end of the partition contacts and adheres tightly to the inner side of the front panel, thereby forming an independent and closed space area inside the cabinet body to prevent mutual interference between the independent spaces.

[0025] In summary, this utility model, through the above-described structural design, overcomes the shortcomings of the prior art and features a reasonable structure, high safety, and strong practicality.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
