Description

Technical Field

[0001] This utility model relates to the field of server rack technology, and more specifically to a heat dissipation structure for a server rack. Background Technology

[0002] A server rack is a freestanding or self-supporting enclosure used to house electrical or electronic equipment. Electronic equipment generates a lot of heat during operation inside the rack, so server racks are equipped with heat dissipation and ventilation structures to dissipate the heat generated inside the rack in a timely manner and ensure the safe use of the equipment.

[0003] The existing cabinet cooling structure has a relatively complete structure and function, which can basically meet the cooling needs of daily use. However, the following problems still exist: When cooling and ventilating the inside of the cabinet, dust filters are installed at the air inlet to prevent dust from the outside air from entering the cabinet. However, with long-term use, dust can clog the dust filters, thereby reducing the cooling and ventilation effect of the cabinet and affecting the safety of equipment use. Therefore, the dust filters need to be cleaned frequently by hand, which is cumbersome.

[0004] In view of this, the present invention proposes a heat dissipation structure for a server rack to solve this problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a heat dissipation structure for a server rack to solve the problems existing in the background art.

The end of the switching shaft away from the drive box is fixed to the center of the dust filter. A collection box is fixedly installed on the outer wall of the cabinet. An opening is opened on the top of the collection box corresponding to the dust filter. A cleaning plate is detachably installed on the side of the collection box away from the cabinet by bolts. Brush bristles are fixedly installed on the cleaning plate inside the collection box.

[0008] Furthermore, a control panel and a drawer lock are respectively provided on the front of the cabinet door, and the control panel is connected to an external control station via a wire.

[0009] Furthermore, a metal protective mesh is fixedly installed on the inner wall of the cabinet door at the air outlet, and the metal protective mesh is made of stainless steel.

[0010] As a further description of the above technical solution: by setting up a metal protective mesh, it is possible to prevent external foreign objects from entering the cabinet through the air outlet.

[0011] Furthermore, an air guide pipe is fixedly installed at the air outlet of the fan, and an air guide port is opened on the surface of the air guide pipe, with the air guide port facing the center section of the cabinet.

[0012] As a further description of the above technical solution: by setting up air ducts, airflow can be directed to the equipment surface on the surface of the stacking board, thereby achieving the purpose of heat dissipation and protection for the equipment.

[0013] Furthermore, a wind shield is slidably connected to the surface of the air duct via a vertical groove. The wind shield is positioned corresponding to the air duct opening. A first threaded set screw is threadedly connected to the surface of the wind shield. Several first positioning holes are equidistantly opened inside the vertical groove. The threaded end of the first threaded set screw is positioned corresponding to the first positioning hole.

[0014] As a further description of the above technical solution: by setting a wind shield, the wind shield can slide inside the vertical slide groove according to the specific position of the equipment, and then the first threaded set screw is used to lock into the first positioning hole for positioning. By using the wind shield to block the air outlet, the airflow can be gathered from the gap of the wind shield and guided to the surface of the equipment, thereby achieving the purpose of improving the heat dissipation effect.

[0015] Furthermore, the stacking plate is movably installed inside the cabinet, and a slide rail is fixedly installed on the inner rear wall of the cabinet.

A fan drives airflow into the cabinet through the air inlet and then exhausts it through the air outlet, achieving the purpose of heat dissipation and protection for the equipment. During use, a dust filter intercepts and filters dust in the airflow. An electric push rod periodically extends and retracts, and based on the meshing of the rack and pinion, it drives the switching shaft and dust filter to rotate. When the dust filter rotates, it comes into contact with the bristles, and a large amount of dust adheres to the surface of the bristles, achieving the effect of cleaning the dust filter. This ensures that the equipment can dissipate heat and ventilate smoothly. After long-term use, the surface of the bristles can be cleaned by opening the cleaning plate. This structure reduces the frequency of dust filter cleaning by the staff, thereby reducing the labor intensity of the staff.

[0027] Reference Figures 1 to 5 This utility model provides a heat dissipation structure for a cabinet, including a cabinet body 1, a cabinet door 2 hinged to the front of the cabinet body 1, a control panel 16 and a drawer lock respectively provided on the front of the cabinet door 2, and the control panel 16 is connected to an external control station via a wire.

[0028] The inner rear wall of the cabinet 1 is provided with a cable inlet 3, and the left and right sides of the cabinet 1 are provided with air inlets 4. The surface of the cabinet door 2 is provided with an air outlet. The cabinet 1 is provided with a stacking board 5.

[0030] A metal protective mesh 17 is fixedly installed on the inner wall of the air outlet of cabinet door 2. The metal protective mesh 17 is made of stainless steel.

[0031] By installing a metal protective mesh 17, external foreign objects can be prevented from entering the cabinet 1 through the air outlet and causing damage.

[0032] The air outlet of the fan 6 is fixedly installed with an air guide pipe 18, and an air guide port 19 is opened on the surface of the air guide pipe 18, with the air guide port 19 facing the center section of the cabinet 1.

[0033] By setting up the air duct 18, the airflow can be directed to the equipment surface on the surface of the stacking plate 5, thereby achieving the purpose of heat dissipation and protection for the equipment.

[0034] A wind shield 20 is slidably connected to the surface of the air duct 18 via a vertical groove. The wind shield 20 is positioned corresponding to the air duct 19. A first threaded set screw 21 is threadedly connected to the surface of the wind shield 20. Several first positioning holes are equidistantly opened inside the vertical groove. The threaded end of the first threaded set screw 21 is positioned corresponding to the first positioning hole.

[0035] It is worth noting that by setting the wind shield 20, the wind shield 20 can slide inside the vertical groove according to the specific position of the equipment, and then the first threaded set screw 21 is used to lock into the first positioning hole for positioning. By using the blocking effect of the wind shield 20 on the air outlet, the airflow can be gathered from the gap of the wind shield 20 and guided to the surface of the equipment, thereby achieving the purpose of improving the heat dissipation effect.
