Description

Technical Field

[0001] The present invention relates to the field of network devices, and specifically to a network cabinet convenient for heat dissipation. Background Art

[0002] A network cabinet is a cabinet for installing various panels, plug-in boxes, electronic components, and electronic devices. The structural requirements of the network cabinet include good rigidity, strength, as well as good electromagnetic isolation, grounding, noise isolation, ventilation and heat dissipation performance.

[0003] The heat dissipation mechanisms of existing network cabinets basically install fixed fans on the top of the cabinet body to cool the inside of the cabinet body through the circulation of air. Once the local temperature inside the cabinet is too high, the existing network cabinets often increase the power of the fans. This coping method often cannot dissipate heat well from the local high-temperature area inside the cabinet, and increasing the power of the fans will additionally waste energy.

[0004] After patent retrieval, it is found that there are patents for dealing with the above situation. For example, a local hot spot elimination system and method for a data center server cabinet with the application number CN201910313434.X and a power distribution cabinet with dust removal and heat dissipation structures with the application number CN202010554298.6. The means for dealing with the local high temperature inside the cabinet in both patents are to install additional liftable fans inside the cabinet. However, this way of adding additional fans will hinder the internal components of the cabinet body, and additionally increase a large number of mechanical structures, which has a great impact on the internal space of the cabinet body. In addition, the form of the fan has a relatively dispersed air outlet, the cooling effect is not good, and the air inlet position where the fan is located is originally a position with a relatively high air temperature, and the heat dissipation effect is also very poor. Summary of the Invention

[0005] The purpose of the present invention is to provide a network cabinet convenient for heat dissipation to solve the above problems.

[0006] The above technical purpose of the present invention is achieved through the following technical solutions: A network cabinet convenient for heat dissipation, including a cabinet body, a glass door is installed on the cabinet body. The cabinet body includes a top cover and two side plates. A pair of columns are installed inside the cabinet body, and at least one mounting rack is erected between the columns. A plurality of heat dissipation fans are installed at the bottom of the top cover, and ventilation holes corresponding to the positions of the heat dissipation fans are opened at the top of the top cover;

[0007] A temperature sensor is fixedly installed on the mounting rack, and a ventilation hose is fixedly installed between the ventilation hole and the corresponding heat dissipation fan;

[0008] The heat dissipation fans are divided into two columns, left and right. Each column of heat dissipation fans is fixed to a rotating shaft through a connecting piece. The rotating shaft is fixed to the motor shaft of the first motor, and the first motor is fixedly installed inside the cabinet;

[0009] A wind guide box is fixedly installed on the inner side of each side plate. A wind guide groove is formed in the wind guide box. A wind guide pipe communicating with the wind guide groove is fixedly installed on the inner side of the wind guide box. Each wind guide pipe corresponds to one of the heat dissipation fans. Ventilation openings are formed in the wind guide box, and the number of the ventilation openings is the same as that of the mounting brackets. The ventilation openings are located at the positions corresponding to the mounting brackets, and an opening and closing assembly is installed in the ventilation openings;

[0010] A control terminal is also installed inside the cabinet.

[0011] Preferably, the opening and closing assembly includes a rotating rod rotatably arranged in the ventilation opening. The rotating rod is fixed to the motor shaft of the second motor. A first baffle and a second baffle are respectively fixed on both sides of the rotating rod. A first sealing plate is fixed to the inner wall of the upper side of the ventilation opening, and a second sealing plate is fixed to the inner wall of the lower side of the ventilation opening. The first sealing plate is in sealing fit with the first baffle, and the second baffle is in sealing fit with the second sealing plate.

[0012] Preferably, a bearing seat is fixedly installed at the bottom of the top cover, and the bearing seat is used to support the rotating shaft.

[0013] Preferably, the ventilation hose is a three-proof cloth with a steel ring or polyurethane with a steel ring.

[0014] Preferably, a sealing layer is installed at the position of the first sealing plate facing the first baffle; a sealing layer is also installed at the position of the second sealing plate facing the second baffle; a sealing strip is fixed to the inner wall of the wind guide groove corresponding to each first baffle, and there is also a sealing layer on the top of the sealing strip.

[0015] Preferably, the sealing layer is made of rubber or silica gel.

[0016] Preferably, a wind guide plate is fixedly installed at the top of the inner part of the wind guide groove. The wind guide plate is inclined and faces the wind guide pipe.

[0017] In summary, the present invention has the following beneficial effects:

[0018] The heat dissipation fans in the present application are divided into two columns, left and right. Each column of heat dissipation fans is fixed to a rotating shaft through a connecting piece, and the rotating shaft is fixed to the motor shaft of the first motor;

[0019] A wind guide box is fixedly installed on the inner side of each side plate. A wind guide groove is formed in the wind guide box. A wind guide pipe communicating with the wind guide groove is fixedly installed on the inner side of the wind guide box. The wind guide pipes respectively correspond to one of the heat dissipation fans. Ventilation openings equal in number to the mounting brackets are formed in the wind guide box. The ventilation openings are located at the positions corresponding to the mounting brackets. An opening and closing assembly is installed in the ventilation openings. The opening and closing assembly is used to close or open the ventilation openings; a control terminal is also installed in the cabinet. When the temperature sensor detects that the temperature is too high, it means that the area where the temperature sensor is located on the mounting bracket is locally overheated. After receiving the data, the control terminal controls two first motors to start; the left first motor drives the heat dissipation fans in the left row to be completely attached to the left wind guide pipe. The advantage of complete attachment is that all the air discharged by the heat dissipation fans will be converged at the wind guide pipe, optimizing the heat dissipation effect; the right first motor drives the right rotating shaft to rotate, so that the heat dissipation fans in the right row are completely attached to the right wind guide pipe; by controlling the opening and closing assembly, the ventilation opening at this place is opened; the control terminal controls the motor of the heat dissipation fans on one side to reverse, so that the heat dissipation fans on one side suck the air in the cabinet out;

[0020] Generally speaking, the heat dissipation fans on one side suck the air with lower temperature outside through the ventilation holes and ventilation hoses. The sucked air is completely converged through the wind guide pipes. The converged air enters the wind guide groove and is discharged from the opened ventilation opening to the mounting bracket with locally too high temperature for centralized heat dissipation. Moreover, the heat dissipation air is the air with lower temperature sucked from outside, and the heat dissipation effect is good. The opening at the ventilation opening is relatively small, which has the effect of accelerating the wind speed and can also blow out the cotton wool or dust that may exist at the mounting bracket. The heat dissipation fans on the other side suck the hot air at the mounting bracket with too high temperature through the ventilation holes, ventilation hoses, wind guide grooves and ventilation openings and discharge it to the outside, and will also take away the blown cotton wool or dust. It can not only achieve centralized heat dissipation for the position with locally too high temperature, but also take away the cotton wool or dust that may cause the too high temperature situation, fundamentally solving the situation of locally too high temperature, and strengthening the overall safety performance while enhancing the heat dissipation effect.

Detailed implementation manners

[0031] Combined with the attached Figures 1-8 A network cabinet convenient for heat dissipation, comprising a cabinet 11, a glass door 12 is installed on the cabinet 11, the cabinet 11 includes a top cover 13 and two side plates 15, a pair of columns 16 are installed in the cabinet 11, at least one mounting rack 17 is erected between the columns 16, various panels, plug-in boxes, electronic components and electronic devices are installed on the mounting rack 17, a temperature sensor 18 is fixedly installed on the mounting rack 17, and the temperature sensor 18 is used for the temperature at its location;

[0032] A number of cooling fans 21 are installed at the bottom of the top cover 13, and ventilation holes 14 corresponding to the positions of the cooling fans 21 are opened at the top of the top cover 13. Under normal circumstances, the cooling fans 21 are started, and the cold air from the outside is introduced into the cabinet 11 through the ventilation holes 14 for heat dissipation;

[0033] The heat dissipation fan 21 is divided into left and right columns. Each column of the heat dissipation fan 21 is fixed on a rotating shaft 29 through a connecting piece 30. The rotating shaft 29 is fixed to the motor shaft of the first motor 22. The first motor 22 is fixedly installed in the cabinet 11. A bearing seat 31 is fixedly installed at the bottom of the top cover 13. The bearing seat 31 is used to support the rotating shaft 29;

[0034] A wind guide box 19 is fixedly installed on the inner side of each side plate 15. A wind guide groove 32 is formed in the wind guide box 19. A wind guide pipe 20 communicating with the wind guide groove 32 is fixedly installed on the inner side of the wind guide box 19. Each wind guide pipe 20 corresponds to one of the heat dissipation fans 21. A ventilation opening 37 with the same number as the installation brackets 17 is formed in the wind guide box 19. The ventilation opening 37 is located at the position corresponding to the installation bracket 17. An opening and closing assembly 40 is installed in the ventilation opening 37. The opening and closing assembly 40 is used to close or open the ventilation opening 37. The opening and closing assembly 40 includes a rotating rod 24 rotatably arranged in the ventilation opening 37. The rotating rod 24 is fixed to the motor shaft of the second motor 27. A first baffle 25 and a second baffle 23 are respectively fixed on both sides of the rotating rod 24. A first sealing plate 26 is fixed to the upper inner wall of the ventilation opening 37. A second sealing plate 39 is fixed to the lower inner wall of the ventilation opening 37. When the first sealing plate 26 is in close contact and sealed with the first baffle 25, and the second baffle 23 is in close contact and sealed with the second sealing plate 39, a ventilation hose 28 is fixedly installed between the ventilation hole 14 and the corresponding heat dissipation fan 21;

[0035] A control terminal is also installed in the cabinet 11. The control terminal is used to receive the data fed back by the temperature sensor 18 and control the operation of each motor in the present application according to the data situation;

[0036] When the temperature sensor 18 detects that the temperature is too high, it means that the installation bracket 17 where the temperature sensor 18 is located is locally overheated. After receiving the data, the control terminal controls the two first motors 22 to start; the left first motor 22 drives the left rotating shaft 29 to rotate, so that the left row of the heat dissipation fans 21 is completely attached to the left air duct 20. The advantage of complete attachment is that all the air discharged by the heat dissipation fans 21 will be converged at the air duct 20, optimizing the heat dissipation effect; the right first motor 22 drives the right rotating shaft 29 to rotate, so that the right row of the heat dissipation fans 21 is completely attached to the right air duct 20; the second motor 27 in the ventilation opening 37 at the corresponding position of the installation bracket 17 where the temperature sensor 18 is located is controlled by the control terminal to start. The second motor 27 drives the rotating rod 24 to rotate, and the rotating rod 24 drives the first baffle 25 and the second baffle 23 to rotate to the horizontal, so that the ventilation opening 37 at this place is opened; the control terminal controls the motor of one side of the heat dissipation fans 21 to reverse, so that one side of the heat dissipation fans 21 sucks the air in the cabinet 11 out;

[0037] Generally speaking, one side of the heat dissipation fans 21 sucks the air with lower temperature outside through the ventilation holes 14 and the ventilation hoses 28. The sucked air is completely converged through the air duct 20. The converged air enters the air guide groove 32 and is discharged to the installation bracket 17 with locally too high temperature through the opened ventilation opening 37 for centralized heat dissipation. The opened opening at the ventilation opening 37 is relatively small, which can accelerate the wind speed and blow out the cotton wool or dust that may exist at the installation bracket 17. The heat dissipation fans 21 on the other side suck the hot air at the installation bracket 17 with too high temperature through the ventilation holes 14, the ventilation hoses 28, the air guide groove 32 and the ventilation opening 37 and discharge it to the outside, and also take away the blown cotton wool or dust. It can not only realize the centralized heat dissipation of the position with locally too high temperature, but also take away the cotton wool or dust that may cause the too high temperature situation, fundamentally solve the situation of locally too high temperature, and strengthen the overall safety performance while enhancing the heat dissipation effect.

[0038] It should be particularly noted that the ventilation hose 28 is a directly purchased product, and its main materials can be three-proof cloth with steel rings, polyurethane with steel rings, etc.

[0039] In addition, to enhance the sealing performance between the first baffle 25 and the first sealing plate 26, a sealing layer is installed at the position of the first sealing plate 26 facing the first baffle 25; to enhance the sealing performance between the second baffle 23 and the second sealing plate 39, a sealing layer is also installed at the position of the second sealing plate 39 facing the second baffle 23; to enhance the sealing performance inside the air guide groove 32 after the first baffle 25 rotates, a sealing strip 34 is fixed on the inner wall of the air guide groove 32 corresponding to each first baffle 25. After the first baffle 25 rotates, it will fit and seal with the sealing strip 34, and there is also a sealing layer on the top of the sealing strip 34.

[0040] The material of the sealing layer generally uses rubber or silica gel, and the method of applying sealant to the material can also be considered.

[0041] An air guide plate 33 is fixedly installed at the top inside the air guide groove 32. The air guide plate 33 is inclined and faces the air guide pipe 20. The air guide plate 33 is used to guide the air entering from the air guide pipe 20.

[0042] Usage method:

[0043] Under normal circumstances, the control terminal controls each heat dissipation fan 21 to start, and introduces the cold air from the outside into the cabinet 11 through the ventilation holes 14 for heat dissipation;

[0044] When the temperature sensor 18 detects that the temperature is too high, it means that the installation rack 17 where the temperature sensor 18 is located is locally overheated. After receiving the data, the control terminal controls the two first motors 22 and the second motor 27 corresponding to the installation rack 17 with local overheating to start;

[0045] The left first motor 22 drives the left rotating shaft 29 to rotate, so that the heat dissipation fans 21 in the left column are completely attached to the left air guide pipe 20;

[0046] The right first motor 22 drives the right rotating shaft 29 to rotate, so that the heat dissipation fans 21 in the right column are completely attached to the right air guide pipe 20;

[0047] The second motor 27 in the ventilation opening 37 corresponding to the installation rack 17 where the temperature sensor 18 is located is controlled by the control terminal to start. The second motor 27 drives the rotating rod 24 to rotate, and the rotating rod 24 drives the first baffle 25 and the second baffle 23 to rotate to the horizontal position, so that the ventilation opening 37 at that place is opened;

[0048] The control terminal controls the motor of the heat dissipation fan 21 on one side to reverse, so that the heat dissipation fan 21 on one side sucks out the air in the cabinet 11;

[0049] Generally speaking, the heat dissipation fan 21 on one side sucks in the air with a lower temperature from the outside through the ventilation hole 14 and the ventilation hose 28. The sucked air is completely converged through the air duct 20. The converged air enters the air guiding groove 32 and is discharged from the opened ventilation port 37 to the mounting bracket 17 with a locally excessive temperature for centralized heat dissipation. The opening of the ventilation port 37 is relatively small, which can accelerate the wind speed and also blow out the cotton wool or dust that may exist at the mounting bracket 17. The heat dissipation fan 21 on the other side sucks away the hot air at the mounting bracket 17 with an excessive temperature through the ventilation hole 14, the ventilation hose 28, the air guiding groove 32 and the ventilation port 37 and discharges it to the outside, and also takes away the blown cotton wool or dust. It can not only achieve centralized heat dissipation for the position with locally excessive temperature, but also take away the cotton wool or dust that may cause the excessive temperature situation.
