Description

Technical Field

[0001] The present invention relates to the field of network communication cabinet equipment, and more specifically, to a network communication cabinet heat exchange device. Background Art

[0002] Network communication equipment refers to various hardware devices used to support network data transmission.

[0003] Network communication equipment cabinets are very common in data centers, enterprise computer rooms, and the environments of network service providers. They are crucial for ensuring the safe operation of network equipment. For the speed of network equipment information transmission, the faster the better. The fundamental reason affecting the speed of network equipment information transmission is still the strength of the emitted signal. The stronger the signal, the faster the information transmission speed. Furthermore, the strength of the signal emitted by network communication equipment is affected by temperature. Firstly, high temperature will increase the loss on the signal path, resulting in signal attenuation, which will affect the signal strength and transmission quality, especially more obvious in high-speed signal transmission. Secondly, high temperature will also affect the electronic components inside the network communication equipment, and even damage the electronic components inside the network communication equipment, resulting in the network communication equipment being unable to work properly. Therefore, a heat exchange device for cooling and heat dissipation is often provided inside the existing network communication equipment to dissipate heat inside the network communication cabinet.

[0004] The heat exchange devices inside the existing network communication cabinets often adopt the methods of fans or refrigeration chips. For large network cabinets, due to the large number of lines inside the network cabinet and the influence of the self-gravity of the lines, it is inevitable that the lines will stick together and pile up. The heat generated by multiple lines together is extremely large. The above two common heat dissipation methods can only cool the overall temperature inside the cabinet. At the position where multiple lines are closely attached, the temperature between the lines is much higher than the overall temperature inside the cabinet. After long-term use, the leather wires on the surface of the lines will age and even be damaged, and short circuits may occur due to arcing between the lines. In order to ensure the safety of the network communication cabinet during use, it is necessary to optimize these two common heat exchange devices. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a network communication cabinet heat exchange device.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] A network communication cabinet heat exchange device, including a frame, inside which a cooling pipe is fixedly arranged. An installation plate is fixedly installed on the inner wall of the frame. The inside of the frame is divided into two parts, a cooling cavity and an installation cavity from the inside to the outside. The cooling cavity and the installation cavity are separated by the installation plate. Multiple groups of exhaust fans are arranged at the top and bottom of the frame, and each group of exhaust fans is arranged in the installation cavity. Each group of exhaust fans at the top of the frame exports the gas inside the installation cavity out of the frame. A dust discharge port communicating with the outside is opened at the bottom of the frame, and the exhaust fans at the bottom of the frame import the gas inside the installation cavity into the dust discharge port. Multiple groups of jacks for air intake are opened on the back of the frame, and multiple groups of cooling holes are opened on the cooling pipe.

[0008] Further, a blowing component is also arranged inside the frame. The blowing component includes a limiting rod fixedly installed on the inner wall of the cooling hole.

A reciprocating lead screw is rotatably and sealedly arranged on the cooling pipe. One end of the reciprocating lead screw extends into the cooling pipe and is fixedly connected to a gear. The gear meshes with the toothed plate. A fan blade is fixedly sleeved on the outer surface of the reciprocating lead screw at the end outside the cooling pipe. A blade cover is fixedly sleeved on the outer surface of the reciprocating lead screw. The fan blade is arranged in the blade cover. Multiple groups of short rods are fixedly installed on the outer surface of the blade cover. The blade cover is fixedly connected to the outer surface of the cooling pipe through multiple groups of short rods.

[0009] Further, a wire management component is arranged on the outer surface of the cooling pipe. The wire management component includes a double-arm rod fixedly sleeved on the reciprocating lead screw. Both ends of the double-arm rod are fixedly connected to wire management blocks. A guide rod is fixedly connected to the outer surface of the cooling pipe. One end of the guide rod away from the cooling pipe penetrates through the wire management block and is fixedly connected to the installation plate. The wire management block is slidably sleeved on the outer surface of the guide rod. A rectangular groove penetrating both ends of the wire management block is opened on the wire management block. Rotating columns are rotatably arranged at both ends of the rectangular groove. A reset spring is fixedly connected to the top of the inner wall of the rectangular groove. The bottom of the reset spring is fixedly connected to an upper pressure plate. A downward sliding cavity is opened at the bottom of the wire management block. A thrust spring is fixedly connected to the bottom of the inner wall of the downward sliding cavity. The top of the thrust spring is fixedly connected to a lower pressure plate. The lower pressure plate is slidably arranged in the downward sliding cavity.

[0010] Further, an upward sliding cavity is opened at the top of the wire management block. A sliding rod is slidably arranged in the upward sliding cavity. The bottom of the sliding rod is fixedly connected to the upper pressure plate. A steel wire rope is slidably arranged inside the wire management block. Multiple groups of stretching blocks are equidistantly arranged on one side of the outer surface of the guide rod. A stretching cavity for the stretching blocks to slide is opened inside the wire management block. The bottom end of the steel wire rope is fixedly connected to the bottom of the inner wall of the stretching cavity. The top end of the steel wire rope is fixedly connected to the top of the sliding rod. The reset spring is sleeved on the outer surface of the sliding rod.

[0011] Further, the cooling pipe is composed of a plurality of interconnected U-shaped elbows. The water inlet end of the cooling pipe opens downward, and the water outlet end of the cooling pipe opens upward. The cooling pipe pumps cooling water into the interior through an external water pump, and the water inlet end of the cooling pipe is communicated with an external cooling water pipe.

[0012] Further, the cooling pipe is not communicated with the outside through the cooling holes, and the upper and lower ends of the limiting rod are respectively fixedly connected to the inner walls of two adjacent cooling holes.

[0013] Further, both ends of the reciprocating lead screw have no threads, and the gear, the fan blade and the blade cover are all arranged at the threadless part of the reciprocating lead screw. The end of the reciprocating lead screw far from the cooling pipe is rotatably connected to the mounting plate.

[0014] Further, the size between two adjacent pipelines of the cooling pipe is the same as the pipe diameter of the cooling pipe.

[0015] Further, the upper pressing plate and the lower pressing plate are symmetrically arranged up and down, and both the upper pressing plate and the lower pressing plate are arc plates. The inner arc surfaces of the upper pressing plate and the lower pressing plate are smoothly designed. The rotating column is made of rubber, and the two groups of rotating columns can produce extrusion with the cable.

[0016] Further, the size of the stretching cavity is larger than that of the stretching block. The part of the steel cable located in the stretching cavity is in contact with the outer surface of the guide rod. The stretching block is made of rubber and its surface is not smooth. The stretching block is designed in a hemispherical shape.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] (1) By arranging the cooling pipe and the exhaust fan in the present invention, the cooling water in the cooling pipe will pass through the inner wall of the cooling hole to cool the surface of the circuit attached to the cooling hole, and can also isolate each circuit, reducing the situation that due to too many circuits, the circuits sag due to their own gravity and contact and pile up with each other. It can better cool the circuits, reduce the problem that the surface temperature of the circuits is much higher than the temperature inside the rack, resulting in overheating and short-circuiting of the circuits and causing fire, ensuring the safety of the network communication cabinet during use and improving the heat dissipation effect of the network communication cabinet.

[0019] (2) By arranging the cooling pipe, the installation cavity and the cooling cavity in the present invention, the heat is exchanged between the space between two adjacent pipelines and the cooling pipe, so that the external hot air is cooled and then blown into the interior of the rack, thereby achieving the effect of cooling the entire interior of the rack. The air entering the cooling cavity is pre-cooled, and the temperature of the air entering the installation cavity is reduced. It can make the temperature of the air in the cooling cavity lower than the temperature without the cooling pipe after the heat exchange of air at different temperatures, improving the heat exchange rate of the air in the installation cavity and further improving the heat dissipation effect.

[0020] (3) Through the blower assembly provided in the present invention, the flow of the coolant in the cooling pipe causes the turbine to rotate, and then the reciprocating lead screw rotates, driving the fan blade and the gear to rotate coaxially, thereby achieving the effect of accelerating the flow of cold air inside the rack, improving the heat exchange efficiency of the air inside the rack, further enhancing the heat dissipation effect of the network communication cabinet. At the same time, the design of the blade cover can prevent the fan blade from getting caught in the line during high-speed rotation, avoiding the situation of line damage and ensuring the safety of the line, further improving the safety during the use of the network communication cabinet.

[0021] (4) Through the wire management assembly provided in the present invention, during the movement of the wire management block along the surface of the guide rod, the dust on the surface of the line can be scraped off, reducing the dust accumulation on the surface of the line, preventing the line skin from exchanging heat with the air, and thus avoiding the situation that affects the heat dissipation effect of the line, so as to further improve the heat dissipation effect inside the rack.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 to 8 , a heat exchange device for a network communication cabinet, including a frame 1, a cooling pipe 2 is fixedly arranged inside the frame 1, a mounting plate 12 is fixedly installed on the inner wall of the frame 1, the inside of the frame 1 is provided with two parts, namely a cooling cavity 14 and an installation cavity 13 from the inside to the outside, the cooling cavity 14 and the installation cavity 13 are separated by the mounting plate 12, multiple groups of exhaust fans 15 are arranged on both the top and bottom of the frame 1, each group of exhaust fans 15 is arranged in the installation cavity 13, each group of exhaust fans 15 on the top of the frame 1 exports the gas inside the installation cavity 13 out of the frame 1, a dust discharge port 11 communicating with the outside is opened at the bottom of the frame 1, the exhaust fans 15 at the bottom of the frame 1 import the gas inside the installation cavity 13 into the dust discharge port 11, multiple groups of insertion holes 111 for air intake are opened on the back of the frame 1, and multiple groups of cooling holes 21 are opened on the cooling pipe 2.

[0034] The cooling pipe 2 is composed of multiple interconnected U-shaped bent pipes, the water inlet end of the cooling pipe 2 opens downward, and the water outlet end of the cooling pipe 2 opens upward. The cooling pipe 2 pumps cooling water into the inside through an external water pump, and the water inlet end of the cooling pipe 2 is communicated with an external cooling water pipe.

[0035] The cooling pipe 2 will not communicate with the outside through the cooling holes 21, and the upper and lower ends of the limit rod 33 are respectively fixedly connected to the inner walls of two adjacent cooling holes 21.

[0036] The dimension between two adjacent pipelines of the cooling pipe 2 is the same as the pipe diameter of the cooling pipe 2.

[0037] When installing network communication equipment inside a network communication cabinet, first insert the line through the jack 111 on the back of the rack 1 into the interior of the rack 1. Subsequently, pass the line passing through the rack 1 through the cooling holes 21 of the cooling pipe 2 and install it on the network communication equipment on the mounting plate 12, then the installation of the network communication equipment on the rack 1 can be completed. When the network communication equipment inside the network communication cabinet is working, first start the exhaust fan 15 to suck the air outside the rack 1 into the interior of the rack 1 through the jack 111 without inserting the line, and after exchanging heat inside the rack 1, leave the interior of the rack 1. Then start the water pump to send cooling water into the cooling pipe 2. At this time, the cooling water in the cooling pipe 2 will pass through the inner wall of the cooling hole 21 to cool the surface of the line fitting in the cooling hole 21. Since one cooling hole 21 corresponds to one line, it can isolate each line, reducing the situation where due to too many lines, the lines sag due to their own gravity and contact and pile up with each other, enabling better cooling of the lines, reducing the problem that the surface temperature of the lines is much higher than the temperature inside the rack 1, resulting in overheating and short - circuit of the lines and causing a fire, ensuring the safety of the network communication cabinet during use and improving the heat dissipation effect of the network communication cabinet;

[0038] Since the size between two adjacent pipelines of the cooling pipe 2 is the same as the pipe diameter of the cooling pipe 2, the air entering the interior of the rack 1 through other un - plugged jacks 111 has enough space to exchange heat with the cooling pipe 2 through the space between two adjacent pipelines, cooling the outside hot air and then blowing it into the interior of the rack 1, thus achieving the effect of cooling the entire interior of the rack 1. Cooling the air entering the cooling chamber in advance and reducing the temperature of the air entering the installation chamber 13 can make the temperature of the air in the cooling chamber lower than that without the cooling pipe 2 after the heat exchange of air at different temperatures, improving the heat exchange rate of the air in the installation chamber 13 and further enhancing the heat dissipation effect;

[0039] It should be specifically noted here that: the aperture of the cooling hole 21 can be designed according to the diameter of the line in use.

[0040] Such as Figures 1 to 7As shown in the figure, a blowing component 3 is further arranged inside the frame 1. The blowing component 3 includes a limiting rod 33 fixedly installed on the inner wall of the cooling hole 21. A turbine 31 is rotatably sleeved on the outer surface of the limiting rod 33. A ring of toothed plate 32 is fixedly installed on the outer ring of the turbine 31. A reciprocating lead screw 34 is rotatably and sealingly arranged on the cooling pipe 2. One end of the reciprocating lead screw 34 extends into the cooling pipe 2 and is fixedly connected to a gear 35. The gear 35 meshes with the toothed plate 32. A fan blade 36 is fixedly sleeved on the outer surface of the reciprocating lead screw 34 at the end outside the cooling pipe 2. A blade cover 37 is fixedly sleeved on the outer surface of the reciprocating lead screw 34. The fan blade 36 is arranged in the blade cover 37. A plurality of short rods 38 are fixedly installed on the outer surface of the blade cover 37. The blade cover 37 is fixedly connected to the outer surface of the cooling pipe 2 through the plurality of short rods 38.

[0041] Both ends of the reciprocating lead screw 34 have no threads, and the gear 35, the fan blade 36 and the blade cover 37 are all arranged at the threadless part of the reciprocating lead screw 34. One end of the reciprocating lead screw 34 far from the cooling pipe 2 is rotatably connected to the mounting plate 12.

[0042] When the water pump injects cooling water into the cooling pipe 2, the water flow of the cooling water will drive the turbine 31 to rotate, and then through the toothed plate 32 on the surface of the turbine 31, the gear 35 meshing with the toothed plate 32 will rotate. When the gear 35 rotates, through the action of the reciprocating lead screw 34, the fan blade 36 will rotate coaxially with the gear 35, thereby realizing the effect of the fan blade 36 accelerating the circulation of cold air inside the frame 1, improving the heat exchange efficiency of the air inside the frame 1, and further improving the heat dissipation effect of the network communication cabinet;

[0043] Due to the design of the blade cover 37, it can avoid the situation that the fan blade 36 gets caught in the circuit and damages the circuit during the high-speed rotation of the fan blade 36, ensuring the safety of the circuit and further improving the safety during the use of the network communication cabinet;

[0044] It should be particularly noted here that: the blowing direction of the fan blade 36 when rotating is towards the mounting plate 12, and at the same time, the number of toothed plates 32 is more than the number of tooth rows on the gear 35.

[0045] Such as Figures 1 to 5 、 Figure 7 and Figure 8As shown in the figure, a wire management component 4 is provided on the outer surface of the cooling pipe 2. The wire management component 4 includes a bidirectional arm rod 41 fixedly sleeved on the reciprocating lead screw 34. Both ends of the bidirectional arm rod 41 are fixedly connected with wire management blocks 43. A guide rod 42 is fixedly connected to the outer surface of the cooling pipe 2. One end of the guide rod 42 away from the cooling pipe 2 penetrates through the wire management block 43 and is fixedly connected to the mounting plate 12. The wire management block 43 is slidably sleeved on the outer surface of the guide rod 42. A rectangular groove 431 penetrating both ends of the wire management block 43 is provided on the wire management block 43. Rotating columns 44 are rotatably provided at both ends of the rectangular groove 431. A return spring 7 is fixedly connected to the top of the inner wall of the rectangular groove 431. The bottom of the return spring 7 is fixedly connected with an upper pressing plate 48. A lower sliding cavity 433 is provided at the bottom inside the wire management block 43. A thrust spring 45 is fixedly connected to the bottom of the inner wall of the lower sliding cavity 433. The top end of the thrust spring 45 is fixedly connected with a lower pressing plate 46. The lower pressing plate 46 is slidably arranged in the lower sliding cavity 433.

[0046] The upper pressing plate 48 and the lower pressing plate 46 are symmetrically arranged up and down, and both the upper pressing plate 48 and the lower pressing plate 46 are arc plates. The inner arc surfaces of the upper pressing plate 48 and the lower pressing plate 46 are smooth. The rotating columns 44 are made of rubber material, and the two groups of rotating columns 44 can generate extrusion with the cable.

[0047] When wiring, after the line passes through the jack 111 and the cooling hole 21, at this time, the edge of the wire head can be used to lift the upper pressing plate 48 upward, and the wire head is inserted into the rectangular groove 431. At this time, the return spring 7 contracts until the space between the upper pressing plate 48 and the lower pressing plate 46 is sufficient for the line to pass through, and the installation of the line on the wire management block 43 is completed. Then the line is released, so that the return spring 7 rebounds under its own elastic force, pushing the upper pressing plate 48 downward, and the line is fixed jointly by the upper pressing plate 48 and the lower pressing plate 46, completing the insertion action of the line. And the wire management component 4 cooperates with the cooling holes 21 on the cooling pipe 2, which can separate each line and reduce the occurrence of line accumulation;

[0048] During the wire threading process, the two rotating columns 44 clamp the line between the two rotating columns 44 through the contact with the line, realizing the guiding of the line during insertion, and at the same time realizing the rotating effect of the rotating columns 44, which can facilitate the insertion of the line into the rectangular groove 431;

[0049] Under the action of the guide rod 42, the rotating reciprocating lead screw 34 will make the wire management block 43 move to the right along the direction of the guide rod 42 as Figure 7 shown in the figure. Due to the smooth design of the inner arc surfaces of the upper pressing plate 48 and the lower pressing plate 46, when the upper pressing plate 48 and the lower pressing plate 46 move following the wire management block 43, the dust on the surface of the line will be scraped off, reducing the accumulation of dust on the surface of the line, blocking the heat exchange between the wire skin and the air, and further affecting the heat dissipation effect of the line. Therefore, the heat dissipation effect inside the rack 1 can be further improved;

[0050] When the cable management component 4 works, it scrapes the dust on the surface of the circuit. Due to the effect of the fan blade 36, the scraped dust will be blown from the cooling cavity 14 into the installation cavity 13, reducing the accumulation of dust in the cooling cavity 14 and affecting the heat dissipation of the circuit. Further, through the exhaust fan 15 in the installation cavity 13, the dust in the installation cavity 13 is blown out of the frame 1, reducing the accumulation of dust inside the frame 1;

[0051] It should be particularly noted here that when the dust inside the frame 1 adheres to the network communication device, if dust cleaning is required, the most difficult part to clean is the circuit, because there are many and complex circuits, while the dust on the shell of the network communication device can be wiped off with a gentle wipe.

[0052] As Figure 8 shown, a upper sliding cavity 432 is opened at the top inside the cable management block 43. A sliding rod 47 is slidably arranged in the upper sliding cavity 432. The bottom of the sliding rod 47 is fixedly connected to the upper pressing plate 48. A steel cable 5 is slidably arranged inside the cable management block 43. A plurality of stretching blocks 6 are equidistantly arranged on one side of the outer surface of the guiding rod 42. A stretching cavity 434 for the stretching blocks 6 to slide is opened inside the cable management block 43. The bottom end of the steel cable 5 is fixedly connected to the bottom of the inner wall of the stretching cavity 434. The top end of the steel cable 5 is fixedly connected to the top of the sliding rod 47. A return spring 7 is sleeved on the outer surface of the sliding rod 47.

[0053] The size of the stretching cavity 434 is larger than that of the stretching block 6. The part of the steel cable 5 located in the stretching cavity 434 contacts the outer surface of the guiding rod 42. The stretching block 6 is made of rubber and its surface is not smooth. The stretching block 6 is designed in a hemispherical shape.

[0054] Under the action of the reciprocating lead screw, when the cable management block 43 moves forward along the direction of the guiding rod 42 as Figure 8 shown, at this time, the stretching block 6 makes a relative movement with respect to the cable management block 43. At this time, for the steel cable 5 located between the two stretching blocks 6, the stretching block 6 will pull the steel cable 5 in the stretching cavity 434 during the movement. Thus, through the action of the steel cable 5, the sliding rod 47 is pulled to slide upward in the upper sliding cavity 432. The sliding rod 47 drives the upper pressing plate 48 to move upward, thereby loosening the circuit, making the circuit naturally placed on the lower pressing plate 46. At the same time, the return spring 7 contracts. And at this time, the steel cable 5 will also move along the front surface of the stretching block 6 and move to the rear surface of the stretching block 6. At this time, the return spring 7 rebounds, and the steel cable 5 in the stretching cavity 434 resets. The stretching block 6 has no pulling force on the steel cable 5, enabling the sliding rod 47 to quickly slide downward in the upper sliding cavity 432, quickly contacting the circuit through the upper pressing plate 48, realizing the function of shaking the circuit, which can cooperate with the cable management component 4 to shake the circuit while scraping the dust on the surface of the circuit, quickly removing the dust on the surface of the circuit, and improving the dust removal effect.

[0055] Usage method: When installing network communication devices inside a network communication cabinet, first insert the line through the jack 111 on the back of the rack 1 into the interior of the rack 1. Subsequently, pass the line passing through the rack 1 through the cooling holes 21 of the cooling pipe 2 and install it with the network communication device on the mounting plate 12, then the installation of the network communication device on the rack 1 can be completed. When the network communication devices inside the network communication cabinet are working, first start the exhaust fan 15 to suck the air outside the rack 1 into the interior of the rack 1 through the jack 111 where no line is inserted. After exchanging heat inside the rack 1, the air leaves the interior of the rack 1. Then start the water pump to send cooling water into the cooling pipe 2. At this time, the cooling water in the cooling pipe 2 will cool the surface of the line fitting in the cooling hole 21 through the inner wall of the cooling hole 21. Since one cooling hole 21 corresponds to one line, it can isolate each line, reducing the situation where due to too many lines, the lines sag due to their own gravity and contact and pile up with each other, enabling better cooling of the lines, reducing the problem that the surface temperature of the lines is much higher than the temperature inside the rack 1, resulting in overheating and short - circuit of the lines and causing a fire, ensuring the safety of the network communication cabinet during use and improving the heat dissipation effect of the network communication cabinet.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent replacements or changes, and all should be covered by the protection scope of the present invention.
