Description

Technical Field

[0001] The present invention relates to the technical field of server terminals, and in particular to a low-noise server terminal. Background Art

[0002] A server terminal is a computer used to manage and control a server, or a software application that can be used to remotely connect to a server and perform various operations and management tasks. A server terminal allows administrators to remotely log in to a server over the network and execute commands, edit configuration files, execute programs, and so on, just like operating directly on the server locally.

[0003] After searching, the Chinese patent with publication number CN114779897B discloses a low-noise server terminal, including a server housing and a partition, the side wall of the server housing is provided with an air inlet and an exhaust hole, the partition is provided to divide the server housing into a first assembly chamber and a second assembly chamber, the partition is provided with an air vent connecting the first assembly chamber and the second assembly chamber, the air vent is a honeycomb structure, a host and a heat dissipation fan are arranged in the first assembly chamber, the host is arranged on the partition, and the heat dissipation fan is located on one side of the exhaust hole. The present invention can effectively reduce the noise generated by the host and the heat dissipation fan due to vibration, and at the same time, the installation is more stable and not easy to loosen, but when the scheme is actually used, there are still the following shortcomings:

[0004] In the process of using a cooling fan to dissipate heat from the host inside the server housing, although this method can effectively discharge the heat generated by the host during operation, the operating principle of the cooling fan is to generate airflow through rotation to exchange the heat inside the server with the cold air outside, which is actually equivalent to establishing a relatively direct connection channel between the server host and the outside environment. Under such a design, if there is even a trace amount of dust in the outside air, it is possible to be sucked into the server housing as the fan rotates. Over time, this accumulated dust will not only affect the heat dissipation efficiency of the server, because the dust layer will hinder the effective transfer of heat, causing the temperature inside the server to gradually increase, but it may also cause physical damage to the electronic components of the host.

[0005] Therefore, the present application provides a low-noise server terminal to meet the requirements for efficient and clean heat dissipation of the server terminal. Summary of the invention

[0058] 1. This low-noise server terminal, by setting up a valve structure and a cleaning structure, realizes effective filtration of the air entering the heat sink through the use of the valve structure, reduces the entry of impurities such as dust, and at the same time, the valve plate drives the rotation of the cleaning plate through the transmission of the driving bevel gear and the driven bevel gear during the rotation process, and uses flexible bristles to clean the filter screen in real time, avoiding dust accumulation and clogging of the filter screen, and ensuring the filtering effect and the cleanliness of the inside of the heat sink.

At the same time, the opening and closing of the valve structure ensures the sealing of the heat dissipation box and the chassis, and avoids the invasion of external dust. In addition, after flowing through the chassis, the gas re-enters the heat dissipation box through the spiral heat dissipation pipe for circulation, thereby realizing effective heat exchange and heat dissipation and improving the heat dissipation efficiency.

[0060] 3.

[0072] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0074] like Figures 1 to 8As shown, a low-noise server terminal includes a chassis 1 and a mounting frame 2, wherein the mounting frame 2 is fixedly mounted on the inner wall of the chassis 1, and a server host 3 is arranged on the top surface of the mounting frame 2, and further includes: a heat sink 4, which is fixedly mounted on the top surface of the chassis 1, and the bottom surface of the heat sink 4 is arranged as an opening; two communication ports 5, which are symmetrically opened on the top surface of the chassis 1; two cooling fans 6, which are respectively arranged on the inner sides of the two communication ports 5; a driving motor 7, which is fixedly mounted on the inner top surface of the cooling box 4; three driven wheels 8, which are respectively arranged on the top ends of the two cooling fans 6 and the top surface of the chassis 1, and the three driven wheels 8 are connected by synchronous belt transmission; four The spiral air inlet pipes 9 are symmetrically arranged in pairs on the inner side of the heat sink 4, and the top of the spiral air inlet pipes 9 passes through the top surface of the heat sink 4; four groups of valve structures are respectively arranged on the top inner walls of the four spiral air inlet pipes 9; four groups of cleaning structures are respectively arranged on the top outer walls of the four spiral air inlet pipes 9; two spiral heat sinks 12 are symmetrically arranged on the chassis 1, and the two ends of the spiral heat sinks 12 are respectively connected to the heat sink 4 and the chassis 1; two groups of flow structures are respectively arranged on the two spiral heat sinks 12; two sealing boxes 14 are symmetrically fixedly installed on the top surface of the chassis 1; two groups of circulation structures are respectively arranged on the two sealing boxes 14;

[0075] During use, when the server host 3 needs to dissipate heat during operation, the driving motor 7 is turned on to drive the two cooling fans 6 to run through the driven wheel 8 and the synchronous belt. In the initial stage of the operation of the cooling fan 6, air needs to be sucked from the outside of the heat sink 4 through the spiral air intake pipe 9, and the valve structure can filter the inhaled air. At this time, the valve structure is opened, and the valve structure is closed after the air intake is completed, ensuring the sealing of the heat sink 4 and the chassis 1 to avoid being affected by external dust. At the same time, the top of the spiral air intake pipe 9 can be cleaned through the cleaning structure during the opening and closing of the valve structure to avoid dust accumulation. When the gas flows through the chassis 1, the server host 3 can be cooled, and the gas after heat exchange can re-enter the heat sink 4 through the spiral heat pipe 12 for circulation. When the gas flows through the spiral heat pipe 12, the temperature can be effectively reduced under the coordinated use of the flow structure and the circulation structure, so as to continue the circulation heat dissipation.

[0076] like Figure 4 , Figure 5As shown, the valve structure includes: a filter screen plate 101, which is arranged at the top of the spiral air inlet pipe 9; a fixing plate 102, which is fixedly installed on the inner wall of the spiral air inlet pipe 9; a mounting groove 103, which is opened on the side of the fixing plate 102; a rotating shaft 104, which is rotatably installed on the inner wall of the mounting groove 103, and one end of the rotating shaft 104 passes through the spiral air inlet pipe 9; a valve plate 105, which is fixedly sleeved on the outer wall of the rotating shaft 104 located on the inner side of the mounting groove 103, and the outer wall of the valve plate 105 is fitted with the inner wall of the spiral air inlet pipe 9; a limiting block 106, which is fixedly installed on the inner wall of the spiral air inlet pipe 9 at a position above the valve plate 105, and the bottom surface of the limiting block 106 is fitted with the top surface of the valve plate 105; a torsion spring 107, which is sleeved on one end of the rotating shaft 104 located on the outer side of the spiral air inlet pipe 9;

[0077] When the driving motor 7 is turned on in the initial stage of heat dissipation, air needs to be inhaled from the outside. At this time, the valve plate 105 can be rotated through the shaft 104 under the action of the pressure difference between the inside of the heat dissipation box 4 and the outside, so that the valve plate 105 is rotated from a horizontal state to a vertical or inclined state. At this time, the spiral air inlet pipe 9 can be connected to the outside, and the gas can enter the heat dissipation box 4 through the spiral air inlet pipe 9. At the same time, when the gas enters the spiral air inlet pipe 9, it can be filtered through the filter plate 101 to reduce the dust entering the heat dissipation box 4. When the pressure inside the heat dissipation box 4 and the chassis 1 is balanced, the shaft 104 and the valve plate 105 rotate in the opposite direction under the action of the torsion spring 107, and the valve plate 105 is in a horizontal state again under the action of the limit block 106 to block the spiral air inlet pipe 9, thereby ensuring that dust cannot enter the heat dissipation box 4 and the chassis 1.

[0078] like Figure 5 As shown, the cleaning structure includes: a bracket 111, fixedly mounted on the outer wall of the top end of the spiral air inlet pipe 9; a rotating rod 112, rotatably mounted on the inner wall of the bracket 111; a driven bevel gear 113, fixedly mounted on the bottom end of the rotating rod 112; a driving bevel gear 114, fixedly mounted on the end of the rotating shaft 104 located outside the spiral air inlet pipe 9, and the driven bevel gear 113 is meshed with the driving bevel gear 114; a mounting seat 115, fixedly mounted on the top end of the rotating rod 112, and the mounting seat 115 is located at the side position of the top end of the spiral air inlet pipe 9; a plurality of cleaning plates 116, which are distributed in an annular array and fixedly mounted on the outer wall of the mounting seat 115, and the bottom surface of the cleaning plate 116 is provided with flexible bristles;

[0079] During the rotation of the valve plate 105 and the rotating shaft 104, the driving bevel gear 114 can be driven to rotate, and the driving bevel gear 114 can be engaged with the driven bevel gear 113, thereby driving the driven bevel gear 113 and the rotating rod 112 to rotate. During the rotation of the rotating rod 112, the cleaning plate 116 can be driven to rotate through the mounting seat 115. During the rotation of the cleaning plate 116, the filter screen plate 101 can be cleaned through the flexible bristles on the bottom surface to prevent dust from adhering to the filter screen plate 101.

[0080] like Figure 1 , Figure 6 , Figure 7 As shown, the circulation structure includes: a jacket 131, which is arranged on the outer wall of the spiral heat dissipation tube 12; two connecting seats 132, which are arranged at both ends of the spiral heat dissipation tube 12, and the connecting seats 132 are connected to both ends of the jacket 131; a liquid guide seat 133, which is respectively arranged on the two connecting seats 132, and the liquid guide seat 133 is connected to the connecting seat 132; two guide tubes 134, which are respectively arranged on the inner walls of the two liquid guide seats 133;

[0081] When the gas flows out along the chassis 1 and enters the spiral heat dissipation tube 12 and flows back into the heat dissipation box 4, the coolant can flow through the jacket 131 on the spiral heat dissipation tube 12 to effectively exchange heat with the gas in the spiral heat dissipation tube 12, so that the gas can continue to be circulated for heat dissipation, and with the coordinated use of the connecting seat 132 and the liquid guide seat 133, the coolant flows from the top end of the spiral heat dissipation tube 12 to the bottom end in the opposite direction of the gas flow direction, further improving the efficiency of heat exchange between the gas and the coolant.

[0082] like Figure 2 , Figure 3 , Figure 8 As shown, the circulation structure includes: a partition 151, which is fixedly mounted on the inner wall of the sealed box 14; a liquid storage chamber 152, which is arranged between the partition 151 and the inner wall of one side of the sealed box 14; a liquid pushing chamber 153, which is arranged between the partition 151 and the inner wall of the other side of the sealed box 14, a liquid inlet seat 16 connected to the liquid storage chamber 152 is arranged on one side of the top surface of the sealed box 14, and a liquid outlet seat 17 connected to the liquid pushing chamber 153 is arranged on the other side of the top surface of the sealed box 14, two conduits 134 are located at the bottom end of the spiral heat dissipation tube 12. One conduit 134 is connected to the liquid inlet seat 16, and the other conduit 134 is located at the top end of the spiral heat dissipation tube 12. Connected to the liquid outlet seat 17; a refrigerant plate 154 is fixedly mounted on the inner bottom wall of the liquid storage chamber 152; a liquid guide port 155 is opened at On the partition 151, the inner walls of the liquid outlet seat 17 and the liquid guide port 155 are installed with one-way valves with opposite flow directions; the piston plate 156 is slidably installed on the inner wall of the liquid pushing chamber 153; the linkage mechanism is arranged between the piston plate 156 and the driving motor 7; the linkage mechanism includes: a push rod 157, which is fixedly installed on the side of the piston plate 156, and the end of the push rod 157 passes through the sealing box 14; a telescopic rod 158, which is fixedly installed on the end of the push rod 157 located outside the sealing box 14; a crank 159, which is fixedly installed between the output end of the driving motor 7 and the top surface of the driven wheel 8; a collar 1510, which is rotatably sleeved on the outer wall of the crank 159, and the telescopic ends of the two telescopic rods 158 are slidably connected to the outer wall of the collar 1510 through a slide groove and a slider;

[0083] When the driving motor 7 is turned on, the crank 159 can be driven to rotate, and the crank 159 can be used to drive the driven wheel 8 to rotate, so as to drive the driven wheel 8. During the rotation of the crank 159, the sleeve 1510 is rotated and sleeved on the outer wall of the crank 159, and the telescopic end of the telescopic rod 158 is slidably connected to the outer wall of the sleeve 1510 through a slide groove and a slider. Therefore, during the rotation of the crank 159, the push rod 157 can be driven to slide back and forth through the telescopic rod 158, so that the piston plate 156 can slide back and forth in the liquid pushing chamber 153. Since a refrigerant plate 154 is installed in the liquid storage chamber 152, the coolant in the liquid storage chamber 152 can be cooled. Under the action of the one-way valve with opposite flow direction in the seat 17, when the piston plate 156 slides away from the partition 151, the coolant in the liquid storage chamber 152 can enter the liquid pushing chamber 153 through the liquid guide port 155, and when the piston plate 156 slides toward the partition 151, the coolant in the liquid pushing chamber 153 can enter the connecting seat 132 at the top through the liquid outlet seat 17 and the conduit 134, and move downward along the jacket 131, and then re-enter the liquid storage chamber 152 through the connecting seat 132, the conduit 134 and the liquid inlet seat 16 at the bottom to be cooled and form a circulation, wherein the working principle and connection method of the refrigerant plate 154 are existing mature technologies and will not be elaborated on here.
