Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat sinks, in particular to a server heat dissipation assembly with an adjustable air duct structure. BACKGROUND

[0002] In the prior art including the above-mentioned patent, the existing heat dissipation units are generally air-cooled, liquid-cooled or a combination of the two. The air-cooled heat dissipation method is still the mainstream method. Since the heat generation of a server is significantly affected by the room temperature, in winter, the room temperature is low and the heat generation of the server is less, so the air volume generated by air-cooled heat dissipation is less. In order to improve the heat dissipation effect of the server, the local air speed needs to be increased. In summer, the heat generation of the server is more, so the air volume generated by the heat dissipation unit is excessive. In order to improve the heat dissipation effect of the server, the air pressure needs to be stabilized.

DETAILED DESCRIPTION

[0021] To make the purposes, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some but not all of the embodiments of the present disclosure. Based on the described embodiments of the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present disclosure.

[0022] Referring to Figures 1-7 The present application provides a server heat dissipation assembly with adjustable air duct structure, which comprises a cabinet 1, and a plurality of heat dissipation units 1.1 are installed on the cabinet 1; further comprising: A main air duct and a plurality of branch air ducts 1.12 are arranged in the heat dissipation unit 1.1; An adjustable force receiving member 1.15 is slidingly connected in the main air duct; A sealing member is installed on each branch air duct 1.12 for adjusting the opening degree of each branch air duct 1.12; A transmission unit is connected at one end with the adjustable force receiving member 1.15 and at the other end with the sealing member; When the adjustable force receiving member 1.15 drives the transmission unit in the sliding stroke in the main air duct, the transmission drives the sealing member to move, adjusts the opening degree of each branch air duct 1.12, and further realizes the contraction to increase the local air speed in the main air duct when the air volume is insufficient, and opens the branch air duct 1.12 to shunt when the air volume is excessive or the noise is high, for stabilizing the pressure loss.

[0023] Specifically, as Figure 1 The cabinet 1 is fixedly connected with a plurality of heat dissipation units 1.1 at linear equidistant positions in the horizontal and vertical directions, each heat dissipation unit 1.1 comprises a main air duct arranged at the axial position and a branch air duct 1.12 arranged around the side of the main air duct, each branch air duct 1.12 is connected with the main air duct, a sealing member is installed on each branch air duct 1.12, the sealing member is installed on each branch air duct 1.12 in a rotating, sliding connection or a combination of rotating and sliding, and the opening degree of each branch air duct 1.12 is adjusted in a rotating, sliding connection or a combination of rotating and sliding of the sealing member.

[0024] The transmission unit is installed in the heat dissipation unit 1.1, one end of the transmission unit is connected with the sealing element, and the other end of the transmission unit is connected with the adjustable force receiving element 1.15. The transmission assembly converts the vertical movement into the linear movement of the sealing element or the rotation of the sealing element to adjust the opening of each branch air duct 1.12. In the embodiment, preferably, the sealing element adjusts the opening of each branch air duct 1.12 by sliding in the radial direction of each branch air duct 1.12. The distance of the adjustable force receiving element 1.15 sliding in the main air duct is related to the air pressure in the heat dissipation unit 1.1. The distance of the adjustable force receiving element 1.15 sliding downward in the main air duct is used to adjust the opening of the sealing element to each branch air duct. In the prior art, the mechanism capable of converting the linear movement into the linear movement includes a connecting rod transmission mechanism, a gear and rack transmission, a crank slider mechanism or a swing rod 1.20 / rocker mechanism, which will not be described in detail herein.

[0025] In the embodiment, as shown in Figure 8 The heat dissipation unit 1.1 is preferably cooled by combining air cooling and water cooling. A spiral condenser pipe is spirally wound outside each heat dissipation unit 1.1, i.e. outside the main air duct and the branch air duct 1.12. The spiral condenser pipes of the heat dissipation units 1.1 are connected in series. Cooling water or fluorinated liquid is circulated in the spiral condenser pipes for cooling. The inlet and outlet of the liquid cooling spiral pipe can be installed according to the installation and manufacturing requirements on site.

[0026] In use, when the heat dissipation fan 1.17 in each main air duct is started, the speed of the heat dissipation fan 1.17 is low due to the low room temperature in winter. At this time, the position of the adjustable force receiving element 1.15 in the heat dissipation unit 1.1 is slightly adjusted or kept stationary. At this time, the opening of the sealing element on the branch air duct 1.12 is small or closed, which is used to improve the local air speed in the main air duct. In summer, the room temperature is high, and the speed of the heat dissipation fan 1.17 is significantly increased. At this time, the air pressure of the main air duct of each heat dissipation unit 1.1 is large, which drives the adjustable force receiving element 1.15 to move in the axial direction of the main air duct. Then, the linear movement of the adjustable force receiving element 1.15 in the axial direction of the main air duct drives the transmission unit to move, and then the transmission unit drives each sealing element to slide in the radial direction of the branch air duct 1.12. The opening of the sealing element on each branch air duct 1.12 is adjusted to realize stable flow or stable pressure.

[0027] Referring to Figures 3-6 In another embodiment of the present application, the main air duct includes a micro neck 1.10 and a stable flow part 1.11. The cross section of the micro neck 1.10 gradually narrows, and the end of the micro neck 1.10 is connected with the stable flow part 1.11. The cross section of the stable flow part 1.11 is constant.

[0028] The main air duct is located at the axial position of the radiator, and each branch air duct 1.12 is connected around the main air duct. Each branch air duct 1.12 is connected to the flow stabilizing part 1.11.

[0029] The adjustable force-bearing component 1.15 slides axially in the main air duct, and the adjustable force-bearing component 1.15 is connected to the main air duct by a first spring 1.14.

[0030] The transmission unit includes multiple connecting rods, one end of which is hinged to the adjustable force-bearing member 1.15, and the other end of the connecting member is hinged to the corresponding sealing member.

[0031] Each linkage includes multiple swing rods 1.20 hinged in the main air duct. One end of each swing rod 1.20 is hinged to a first connecting rod 1.21, and the other end of each swing rod 1.20 is hinged to a second connecting rod 1.22. The other end of each first connecting rod 1.21 is hinged to a corresponding sealing element, and the other end of each second connecting rod 1.22 is hinged to an adjustable force-bearing element 1.15.

[0032] The sealing element includes a sealing cover 1.16 that is slidably connected to each branch duct 1.12, and each sealing cover 1.16 is hinged to its corresponding first connecting rod 1.21.

[0033] Specifically, such as Figure 3 As shown, the main air duct on each heat dissipation unit 1.1 is located at the axial center of the radiator, and branch air ducts 1.12 are arranged around the main air duct. The main air duct is divided into a narrowing neck 1.10 and a flow stabilizing section 1.11. The cross-section of the narrowing neck 1.10 gradually narrows, and its end connects to the flow stabilizing section 1.11. The cross-section of the flow stabilizing section 1.11 is constant. The main air duct is made of high-strength flame-retardant PC+GF20 material to ensure stability at high temperatures and prevent deformation during long-term high-load operation. The cross-section of the main air duct gradually narrows in the central part, with a diameter reduction ratio designed to be 0.75-0.8, ensuring the highest air velocity at this position. That is, the initial width of the air duct is 100 mm, and it narrows to about 75-80 mm at the end, with a total length of 150 mm for the entire narrowing section. This gradual narrowing and acceleration of the air duct increases the local airflow velocity and achieves the best heat dissipation effect. The ends of the branch air ducts 1.12 are parallel to the streamline direction of the air duct to avoid unnecessary eddies and flow resistance.

[0034] The adjustable force receiving piece 1.15 is slidably connected in the axial direction of the main air duct, and is connected with the main air duct through a first spring 1.14, one end of the first spring 1.14 is fixedly connected with the adjustable force receiving piece 1.15, and the other end of the first spring 1.14 is fixedly connected with the main air duct, a sliding groove 1.13 matched with the sealing cover 1.16 is arranged at the radial position of the air inlet of each branch air duct 1.12, a hinged seat is fixedly connected to each branch air duct 1.12, a swing rod 1.20 is hinged to each hinged seat, one end of each swing rod 1.20 is hinged to a first connecting rod 1.21, the end of each first connecting rod 1.21 is hinged to the corresponding sealing cover 1.16, and the other end of each swing rod 1.20 is hinged to a second connecting rod 1.22, and the end of each second connecting rod 1.22 is hinged to the adjustable force receiving piece 1.15.

[0035] In use, when the heat dissipation fan 1.17 in each main air duct is started, the rotational speed of the heat dissipation fan 1.17 is low in winter due to the low room temperature, at this time, the position of the adjustable force receiving piece 1.15 in the heat dissipation unit 1.1 is finely adjusted or kept stationary, at this time, the opening of the sealing element on the branch air duct 1.12 is small or in a closed state, at this time, the local wind speed in the main air duct is increased, when it is summer, at this time, the room temperature is high, the rotational speed of the heat dissipation fan 1.17 is significantly increased, at this time, the air pressure of the main air duct of each heat dissipation unit 1.1 is large, the air pressure drives the adjustable force receiving piece 1.15 to move in the axial direction of the main air duct, and then the adjustable force receiving piece 1.15 moves linearly in the axial direction of the main air duct, drives the second connecting rod 1.22 to rotate, drives the swing rod 1.20 hinged to the second connecting rod 1.22 to move, and then drives the first swing rod 1.20 hinged to the swing rod 1.20 to move, so that the sealing cover 1.16 slides in the radial direction of the branch air duct 1.12, so that the opening of the sealing cover 1.16 on each branch air duct 1.12 is adjusted to open each branch air duct 1.12, and stable flow or stable pressure is achieved.

[0036] Referring to Figures 5-7 In another embodiment of the present application, the heat dissipation fan 1.17 is fixedly installed at the position of the micro neck 1.10 of the main air duct.

[0037] The upper and lower sides of the heat dissipation fan 1.17 are respectively slidably connected with a cleaning brush 1.18, and the cleaning brush 1.18 and the heat dissipation fan 1.17 are connected through a second spring 1.19.

[0038] The transmission groove 1.171 is arranged on the circumferential side of the transmission shaft 1.170 fixedly connected to the two sides of the heat dissipation fan 1.17, and the transmission pin 1.180 matched with the transmission groove 1.171 is fixedly connected to the corresponding position of each cleaning brush 1.18.

[0039] Specifically, a heat dissipation fan 1.17 is fixedly connected at the first end position of the main air duct at the position of the micro neck 1.10, two ends of each heat dissipation fan 1.17 are fixedly connected with a connecting shaft, a cleaning brush 1.18 is sleeved on the circumferential side of the connecting shaft, the cleaning brush 1.18 is located on both sides of the fan blade, each cleaning brush 1.18 moves in the axial direction of the connecting shaft, a transmission groove 1.171 is formed on both sides of the fan blade, the transmission groove 1.171 is a plurality of V-shaped grooves connected in series, the number of each V-shaped groove is equal to the number of the fan blades, and the height of each V-shaped groove is matched with the top end or the tail end of each fan blade, a second spring 1.19 is arranged between each cleaning brush 1.18 and the fan blade, one end of each second spring 1.19 abuts against the heat dissipation fan 1.17, and the other end of the second spring 1.19 is fixedly connected with the corresponding cleaning brush 1.18.

[0040] In use, the connecting shaft is driven to move by the rotation of the fan blade, and then the transmission pin 1.180 on each cleaning brush 1.18 moves in each transmission groove 1.171, so that each cleaning brush 1.18 cleans the dust attached to the fan blade.

[0041] The above only describes some exemplary embodiments of the application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the application. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the application.
