Description

Technical Field

[0001] The utility model relates to the technical field of network servers, and particularly relates to a cabinet-type network server. Background Art

[0002] A network server is the core component of a computer local area network, and the efficiency of the network server directly affects the efficiency of the entire network; in some high-end enterprise servers, due to the complex internal structure and numerous internal devices, some also have many different device units or several servers placed in a single cabinet, and such a server is a cabinet-type server; however, when the above-mentioned device units or servers are powered on and working, they will generate high temperatures. Overheating of the power distribution cabinet will affect the service life of electrical components, and in severe cases, it may even cause accidents such as fires.

[0003] Currently, a general network server cabinet is mechanically cooled by multiple cooling fans, and the multiple cooling fans are arranged on the top of the network server cabinet to extract the high temperature generated inside the cabinet. However, there are also several partitions horizontally arranged inside the network server cabinet for installing device units or servers. These partitions will block the cooling fans from vertically extracting the high temperature generated when the device units or servers are working. That is to say, for a network server cabinet with cooling fans arranged on the top, it cannot specifically extract the high temperature generated between several partitions, and the cooling efficiency is relatively low. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that in the prior art, a network server cabinet with cooling fans arranged on the top cannot specifically extract the high temperature generated between several partitions, and the cooling efficiency is relatively low, and to propose a cabinet-type network server.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A cabinet-type network server, comprising a support frame, a first side plate, a top cover, and more than two cooling fans. The top cover is fixedly installed above the support frame, and several cooling fans are fixedly installed on the top cover. The first side plate is installed on one side of the support frame through several U-shaped connectors II. A guiding plate is fixedly installed between the bottom surface of the top cover and the support frame, and the guiding plate is arranged between several cooling fans. A second side plate is installed on the other side of the support frame, and several air intake holes are arranged on the outer plate of the second side plate, and the outer plate is parallel to the first side plate.

[0007] Preferably, an inner plate is installed in a lifting manner in a card slot on the inner side of the outer plate, and both sides of the card slot are communicated with sliding grooves, and both sides of the inner plate are respectively slidably installed in the sliding grooves.

[0008] Preferably, a number of polyethylene thin wires are bound to the top end of the inner plate and the inner top surface of the card slot.

[0009] Preferably, an electric push cylinder is fixedly installed at the upper end of the card slot. The end of the push rod in the electric push cylinder faces vertically downward and is in contact with the top end of the inner plate.

[0010] Preferably, a number of strip-shaped holes are provided on the inner plate, and the number of strip-shaped holes communicates with the number of air inlet holes correspondingly.

[0011] Preferably, a number of partition plates are fixedly installed inside the support frame, and a number of U-shaped connectors I are fixedly installed between the support frame and the outer plate.

[0012] Compared with the prior art, the utility model provides a cabinet-type network server, which has the following

[0013] Beneficial effects:

[0014] 1. For this cabinet-type network server, first, a number of cooling fans on the left directly extract air for heat dissipation inside the present application, which is the same as the mechanical heat dissipation principle of traditional network server cabinets. Then, the first side plate and the guide plate cooperate to well guide the two cooling fans on the right to extract the air in the right inner cavity of the present application, generating negative pressure on the right side of the number of partition plates. When the network server is working, the high temperature generated by the device unit or the server heats the air between the number of partition plates, reducing the air pressure, attracting and extracting a part of the air to supplement the air pressure, and the incoming gas absorbs the high temperature generated by the device unit or the server. Then, the two cooling fans on the right generate negative pressure on the right side of the number of partition plates, so that the high temperature generated between the number of partition plates can be discharged upward from the right inner cavity part of the present application, that is, the two cooling fans on the right are mainly used to extract the hot air generated between the number of partition plates. Compared with the mechanical heat dissipation of traditional network server cabinets, it can guide the gas flow between the number of partition plates, and can better dissipate heat for the device unit or the server between the number of partition plates, with targeted heat dissipation and better heat dissipation effect.

[0015] 2. When the cabinet - type network server detects high temperature through the temperature sensor and there is a risk of explosion and fire, the temperature sensor will transmit a signal for the push rod to extend to the electric push cylinder. After the push rod in the electric push cylinder is pushed downward, it is used to push the inner plate downward, break the polyethylene thin line on the inner plate, and cover a number of air inlets. As a result, there is a lack of oxygen entering the interior of this application. Coupled with the air extraction function of the cooling fan, the oxygen required for combustion inside this application can be lacking, effectively avoiding the spread of fire inside this application. If a short - circuit also occurs in the circuit where the temperature sensor or the electric push cylinder is located, and the high temperature generated by the accidental short - circuit inside this application is greater than the melting temperature of the polyethylene thin line, the high temperature can fuse the polyethylene thin line. Then, the polyethylene thin line will release the pull on the inner plate, and the inner plate will naturally fall to the lowest position by its own gravity, which can also make the outer plate cover a number of air inlets, effectively preventing the spread of fire.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0023] Referring to the attached Figures 1-4 , a cabinet - type network server, comprising a support frame 1. The support frame 1 is integrally in the shape of a cuboid. A plurality of horizontally - placed partitions 6 are fixedly installed inside the support frame 1. The partitions 6 are mainly used for installing different device units or servers. The left side of the support frame 1 is fixedly installed with a second side plate 3 through a plurality of U - shaped connectors one 8, and the right side of the support frame 1 is fixedly installed with a first side plate 2 through a plurality of U - shaped connectors two 7. The second side plate 3 and the first side plate 2 are parallel to each other. The plurality of U - shaped connectors two 7 and the plurality of U - shaped connectors one 8 are respectively used to reserve a heat - dissipation space between the support frame 1 and the first side plate 2 and the second side plate 3.

[0024] In this embodiment, the second side plate 3 is composed of an outer plate 301 and an inner plate 303. The inner plate 303 is installed in a lifting manner in a card slot 307 inside the outer plate 301. Both sides of the card slot 307 are communicated with sliding grooves 308. The two sides of the inner plate 303 are respectively vertically slidably installed in the two sliding grooves 308. A plurality of air inlet holes 306 are provided on the outer plate 301, and the plurality of air inlet holes 306 are arranged in a matrix - type dense arrangement. A plurality of strip - shaped holes 305 are provided on the inner plate 303, and the plurality of strip - shaped holes 305 are respectively in corresponding communication with the plurality of air inlet holes 306.

[0025] In this embodiment, it can be referred to Figure 3 , a plurality of polyethylene thin lines 304 are tension - bound between the upper top surface of the inner plate 303 and the inner top surface of the card slot 307. That is, the inner plate 303 is hung in the card slot 307 in the outer plate 301 through a plurality of polyethylene thin lines 304. The polyethylene thin lines 304 are made of linear low - density polyethylene material. An electric push cylinder 302 is also fixedly installed at the upper end of the card slot 307. The electric push cylinder 302 is connected to an external power supply through a wire. The push rod in the electric push cylinder 302 is vertically downward, and the push rod in the electric push cylinder 302 is in contact with the upper top surface of the inner plate 303.

[0026] It should be noted that the melting temperature of the linear low-density polyethylene material is approximately 115 - 135 °C. That is, when the high temperature generated by an accidental short circuit inside the present application is higher than the melting temperature of the polyethylene thin wire 304, the polyethylene thin wire 304 can be melted. After several polyethylene thin wires 304 are melted by the high temperature, the broken polyethylene thin wires 304 will release the pulling force on the inner plate 303. The inner plate 303 will naturally fall due to its own gravity. And when the inner plate 303 naturally and stably falls to the lowest position, several strip-shaped holes 305 in the inner plate 303 will be staggered with several air intake holes 306 in the outer plate 301, so that the outer plate 301 covers several air intake holes 306, thereby preventing the side plate two 3 from ventilating.

[0027] Furthermore, it should be noted that the temperature of the cabinet of a general network server is approximately 25 - 35 °C. And according to national standards, when the temperature inside the cabinet is higher than 60 °C, it is in a high-temperature state. Therefore, a temperature sensor is generally installed inside the cabinet, that is, the temperature sensor is fixedly installed on a partition 6 for detecting the temperature inside the present application. When the temperature detected by the temperature sensor is higher than 35 °C, the temperature sensor sends an opening signal to the cooling fan 5 for air extraction and heat dissipation. Information is transmitted between the temperature sensor and the cooling fan 5 and the electric push cylinder 302 through wires respectively. Under the air extraction action of multiple cooling fans 5 in the present application, the temperature inside the application can basically be maintained at 25 - 35 °C. When the temperature detected by the temperature sensor is higher than 60 °C or a higher temperature, which poses a risk of explosion and fire, the temperature sensor does two things: one is to cut off the power supply of the network server, and the other is to send a signal for the push rod of the electric push cylinder 302 to extend. After the push rod in the electric push cylinder 302 is pushed downward, it is used to push the inner plate 303 downward and break the polyethylene thin wire 304 on the inner plate 303 to cover several air intake holes 306, so that there is no oxygen entering the inside of the present application. Coupled with the air extraction action of the cooling fan 5, the oxygen required for combustion inside the present application can be lacking, effectively avoiding the spread of fire inside the present application.

[0028] In this embodiment, a top cover 4 is fixedly installed between the upper top surfaces of the outer plate 301 and the side plate one 2. Six cooling fans 5 are fixedly installed on the top cover 4. The cooling fans 5 are connected to an external power supply through wires, such as Figure 1 and Figure 4 , and the six cooling fans 5 are arranged in a matrix on the top cover 4. The air outlet of each of the six cooling fans 5 is vertically upward, mainly used for extracting the air inside the cavity of the present application. A guide plate 9 is arranged between the four cooling fans 5 on the left and the two cooling fans 5 on the right. The upper and lower ends of the guide plate 9 are respectively fixedly connected to the top cover 4 and the support frame 1.

[0029] It should be added that for network server cabinets of model KH604042JKA and most other existing network server cabinets, there are several small holes on the front and rear cabinet doors for heat dissipation. However, the several small holes on the cabinet doors in the prior art cannot, like the several air inlets 306 in the second side plate 3, close the holes when the temperature inside the cabinet is high. Therefore, a front cabinet door and a rear cabinet door are installed between the outer plate 301 and the front and rear sides of the first side plate 2 in this application, and both have the same structure as the second side plate 3. After the temperature inside the cabinet becomes high, the holes on them can be closed, so that there is a lack of oxygen for combustion support inside the cabinet, effectively avoiding the spread of internal fires in this application.

[0030] In this utility model, when the cabinet-type network server is working and running, multiple device units or servers between several partitions 6 will generate high temperatures, causing the temperature between several partitions 6 to rise rapidly. That is, the air between several partitions 6 is relatively more heated, the air expands and rises, resulting in a smaller air pressure in the low altitude, while the edges and the surrounding areas of several partitions 6 are less heated and the air pressure changes little. Thus, an air pressure difference is generated, and the air in the low altitude will flow from the place with less heat to the place with more heat, that is, the air entering from the second side plate 3, the front cabinet door and the rear cabinet door will flow to supplement the air pressure between several partitions 6 according to the air pressure difference, and the entering air will dissipate heat from the device units or servers between several partitions 6. However, the heat dissipation caused by the air pressure difference solely due to temperature is relatively slow, and generally there are many device units or servers installed in a network server. Therefore, when this application is working properly, it is extremely easy for high temperatures to accumulate inside the cabinet;

[0031] Reference Figure 4 , when the temperature detected by the temperature sensor is greater than 35 °C, the temperature sensor detects and transmits an opening signal to the cooling fans 5. The four cooling fans 5 on the left directly extract air for heat dissipation inside this application, which is the same as the mechanical heat dissipation principle of traditional network server cabinets. Therefore, there are no ventilation holes provided on the first side plate 2 on the right side of this application. Thus, the first side plate 2 cooperates with the guiding plate 9 to well guide the two cooling fans 5 on the right to extract the air in the right inner cavity of this application, creating a negative pressure on the right side of several partitions 6 and making it lower than the air pressure between several partitions 6. That is, after the temperature between several partitions 6 rises and the air pressure decreases, the generated air pressure difference will attract and extract a part of the air to supplement the air pressure, and the entering gas will absorb the high temperature generated by the device units or servers. Then, the two cooling fans 5 on the right create a negative pressure on the right side of several partitions 6, so that the high temperature generated between several partitions 6 can be discharged upward from the right inner cavity part of this application. That is, the two cooling fans 5 on the right are mainly used to extract the hot air generated between several partitions 6. Compared with the mechanical heat dissipation of traditional network server cabinets, it can guide the gas flow between several partitions 6.

[0032] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
