Description

Technical Field

[0001] This utility model relates to the field of heat dissipation device technology, and in particular to a heat dissipation device for a network switch. Background Technology

[0002] With the development of 5G network technology, the efficiency of information transmission and exchange is gradually improving. To ensure accurate interaction and recognition of all information, a large amount of power is often required for processing. Therefore, network switches often generate excess heat as power consumption increases. However, excessive heat can affect normal data transmission and reduce overall efficiency. To ensure the normal operation of network switches, cooling devices are needed to maintain the ambient temperature. However, currently available cooling devices are bulky and cannot be fitted to smaller network switches. Furthermore, their overall cooling efficiency is affected by ambient temperature, failing to adequately dissipate heat and thus not meeting practical usage requirements. Utility Model Content

[0003] The purpose of this utility model is to provide a heat dissipation device for network switches, which solves the technical problems of large device size, inconvenient installation, and low overall heat dissipation efficiency in the prior art, and achieves the technical effect of reducing device size for easy installation and improving overall heat dissipation efficiency.

[0004] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0005] A network switch heat dissipation device includes a mounting base, an air-cooled mounting plate, and a compressed air duct. Two sets of mounting plates for assembly are symmetrically fixed to the lower end of the mounting base. The air-cooled mounting plate is fixed to one side of the mounting base and between the mounting plates. A cooling fan is installed inside the air-cooled mounting plate. One side of the cooling fan has a mounting bracket fixedly connected to the mounting base. The lower end of the air-cooled mounting plate has an opening for cooperating with the cooling fan to deliver air downwards. The compressed air duct is located on the side of the mounting base away from the air-cooled mounting plate. A compressor for compressing cooling air is fixed inside the compressed air duct. One side of the compressed air duct has an air intake duct for supplying air into the compressed air duct. Another side of the compressed air duct has a diffuser duct. The mounting base has an air duct interface near the diffuser duct. The air duct interface passes through a cold air passage on one side of the mounting base. The cold air passage is located below the cooling fan and is used to cooperate with the diffuser duct to cool the air temperature and deliver it to the location requiring heat dissipation.

[0006] As an improvement, the internal air duct of the compression air duct has a spiral converging structure. The width of the air intake air duct is greater than the width of the compression air duct, and the thickness is less than the thickness of the compression air duct. The overall structure is a funnel-shaped structure that contracts towards the compression air duct. The outer shell of the compression air duct is made of thermally conductive metal for heat dissipation of the compressed air inside the compression air duct.

[0007] As an improvement, the compressed air duct is equipped with a compressor inside. The inner fan blades of the compressor cooperate with the compressed air duct to draw in outside air. The rotating shaft of the compressor extends out of the upper end of the compressed air duct. The outer side of the rotating shaft is fitted with fan blades to assist in air cooling of the compressed air duct surface. A fastening connecting ring is provided between the mounting base and the compressed air duct. The fastening connecting ring is fitted on the outer side of the air duct interface to tightly connect the diffuser air duct to the air duct interface. One side of the fastening connecting ring has an ear plate. The inner side of the ear plate has a through hole for detachable connection with the mounting base using bolts.

[0008] As an improvement, a water-cooled mounting plate is provided on the side of the mounting base away from the air-cooled mounting plate. The water-cooled mounting plate is located on the side of the fastening connecting ring away from the compression air duct. A circulation pump is fixed on the side of the water-cooled mounting plate away from the mounting base. A water-cooled motor is provided on one side of the circulation pump to drive the internal pump core of the circulation pump to rotate and promote the flow of coolant. A heat sink is provided on the side of the circulation pump away from the water-cooled mounting plate. A water-cooled fan is provided on the side of the heat sink away from the compression air duct. A guide plate is provided between the water-cooled fan and the heat sink to reduce the internal liquid temperature of the circulation pump.

[0009] As an improvement, the upper end of the water-cooled mounting plate has two sets of pipes connected to the circulating pump. The side of the mounting base away from the water-cooled mounting plate has a flexible hose. The flexible hose is fixedly connected to the mounting base and passes through the mounting base and connects to the pipes via a connector. The flexible hose contains cold water and hot water pipes that are connected to the pipes. The end of the flexible hose away from the mounting base has a heat exchange base. The heat exchange base is made of thermally conductive metal and has a one-way copper tube on its surface for exchanging heat between the coolant and the heat-generating location.

[0010] As an improvement, a connecting rod is fixed to the upper end of the mounting base, and a control module is fixed to the side of the connecting rod away from the air-cooled mounting plate. The control module has a terminal block on the side away from the compressed air duct, and a button is provided at the upper end of the control module. A circuit is provided on one side of the control module to control the cooling fan, compressor and water-cooled motor.

[0011] The beneficial effects of this utility model are as follows: by setting the mounting base and the air-cooled mounting plate, the fan can be installed conveniently, and the cold airflow can be fully directed to the position that needs to be cooled, so as to make full use of the cold airflow. By setting the flat compression air duct, the outside air can be fully drawn in and cooled, and the cold air channel is sent to the fan outlet to achieve cooling. By setting the circulating pump and heat exchange seat structure, the local position can be further cooled efficiently, improving the overall heat dissipation effect. Attached Figure Description

[0016] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0017] like Figures 1 to 3As shown, a network switch heat dissipation device includes a mounting base 1, an air-cooled mounting plate 4, and a compressed air duct 8. Two sets of mounting plates 2 for assembly are symmetrically fixed to the lower end of the mounting base 1. The air-cooled mounting plate 4 is fixed to one side of the mounting base 1 and between the mounting plates 2. A cooling fan 6 is provided inside the air-cooled mounting plate 4. One side of the cooling fan 6 has a mounting bracket 5 fixedly connected to the mounting base 1. The lower end of the air-cooled mounting plate 4 has an opening for downward airflow from the cooling fan 6. The compressed air duct 8 is located on the mounting base 1 away from the air-cooled mounting plate 1. On one side of the mounting plate 4, a compressor 9 for compressing cooling air is fixed inside the compressed air duct 8. An air inlet duct 12 is located on one side of the compressed air duct 8 to supply air into it. A diffuser duct 11 is also located on one side of the compressed air duct 8. An air duct interface 10 is located near the diffuser duct 11 on the mounting base 1. A cold air channel 7 extends through the air duct interface 10 to one side of the mounting base 1. The cold air channel 7 is located below the cooling fan 6 and works in conjunction with the diffuser duct 11 to cool the air and deliver it to the location requiring heat dissipation. The inner side of the mounting plate 2 has through holes for mounting bolts and related clamps to accommodate different network switch shapes and structures.

[0018] The internal air duct of the compression duct 8 has a spiral converging structure. The width of the intake air duct 12 is greater than the width of the compression duct 8, and the thickness is less than the thickness of the compression duct 8. It is also a funnel-shaped structure that tapers towards the compression duct 8. The outer shell of the compression duct 8 is made of thermally conductive metal for heat dissipation of the compressed air inside the compression duct 8. The compression duct 8 contains a compressor 9. The inner fan blades of the compressor 9 cooperate with the compression duct 8 to draw in outside air. The rotating shaft of the compressor 9 extends out of the upper end of the compression duct 8. The outer side of the rotating shaft is fitted with fan blades to assist in air cooling of the surface of the compression duct 8. A fastening connecting ring 3 is provided between the mounting base 1 and the compression duct 8. The fastening connecting ring 3 is fitted on the outer side of the air duct interface 10 to tightly connect the diffuser air duct 11 to the air duct interface 10. One side of the fastening connecting ring 3 has an ear plate with a through hole on the inner side for detachable connection with the mounting base 1 using bolts. The compression duct 8 can be replaced with different diameter models according to air volume requirements. The compression duct 8 has a double-layer spiral structure, with the upper layer connected to the air intake duct 12 and the lower layer connected to the diffuser duct 11.

[0019] When in use, the mounting plate 2 can be assembled and fixed to the network switch structure. At this time, it is necessary to ensure that the air-cooled mounting plate 4 is facing the location requiring cooling, while the air intake duct 12 is away from the heat source, and that there is adequate ventilation and heat exchange around the network switch. Then, connect the power line and start the system. The compressor 9 will continuously draw in outside air through the air intake duct 12, and the air will be cooled during compression through the heat dissipation structure of the compression duct 8. The air pressure will then be reduced through the diffusion duct 11, resulting in cooled air, which will be delivered to the area below the cooling fan 6 via the cold air channel 7. The cooling fan 6 will then blow both the outside air and the cooled air to the required cooling location, achieving efficient heat exchange and reducing the operating temperature of the network switch. In this process, the flat structure can be easily integrated with the network switch for assembly and is convenient for placement and use in confined spaces.

[0020] However, during use, the power connection area of ​​the network switch experiences localized high temperatures. The current air-cooling structure cannot adequately dissipate heat and cool this area, which still affects the operation of the equipment. To further ensure the normal operation of the equipment, the following improvements have been made:

[0021] A water-cooled mounting plate 13 is provided on the side of the mounting base 1 away from the air-cooled mounting plate 4. The water-cooled mounting plate 13 is located on the side of the fastening connecting ring 3 away from the compression air duct 8. A circulating pump 14 is fixed on the side of the water-cooled mounting plate 13 away from the mounting base 1. A water-cooled motor 17 is provided on one side of the circulating pump 14 to drive the internal pump core of the circulating pump 14 to rotate and promote the flow of coolant. A heat sink 15 is provided on the side of the circulating pump 14 away from the water-cooled mounting plate 13. A water-cooled fan 16 is provided on the side of the heat sink 15 away from the compression air duct 8. A guide plate is provided between the water-cooled fan 16 and the heat sink 15 to reduce the internal liquid temperature of the circulating pump 14. The upper end of the water-cooled mounting plate 13 has two sets of pipes connected to the circulating pump 14. The mounting base 1, on the side away from the water-cooled mounting plate 13, has a flexible hose 21. The flexible hose 21 is fixedly connected to the mounting base 1 and passes through the mounting base 1 via a connector to connect to the pipes. The flexible hose 21 contains cold and hot water pipes connected to the pipes. The end of the flexible hose 21 away from the mounting base 1 has a heat exchange seat 22. The heat exchange seat 22 is made of thermally conductive metal and has a unidirectional copper tube on its surface for heat exchange between the coolant and the heat-generating location. The heat exchange seat 22 can be fitted with corresponding fixtures according to the power supply location or connector shape, thereby ensuring a close fit to the structural surface for heat exchange, guaranteeing the stability of the structural installation, and improving heat dissipation and cooling efficiency.

[0022] When in use, the operator can inject coolant into the circulating pump 14 through the water injection hole at one end, and then start the water-cooled motor 17 to make it flow fully in the pipeline. During the process, the coolant will work with the water-cooled fan 16 and heat sink 15 at the circulating pump 14 to exchange heat with the outside, ensuring that the coolant is kept at a low temperature. Then it is sent to the heat exchange base 22 through the pipeline and hose. At this time, the heat exchange base 22, which is close to the heat source, will be continuously cooled by the coolant, thereby reducing the temperature of the heat source through heat exchange and realizing the stable operation of the equipment.

[0023] A connecting rod 20 is fixed to the upper end of the mounting base 1. A control module 18 is fixed to the side of the connecting rod 20 away from the air-cooled mounting plate 4. The control module 18 has a terminal block 19 on the side away from the compressed air duct 8. The upper end of the control module 18 has a button, and one side has wiring for control connection with the cooling fan 6, compressor 9, and water-cooled motor 17. The control module 18 can interact with a remote control device via a wireless signal transmission module, thereby facilitating remote control by the operator.

[0024] When in use, the operator can connect the lines to the terminal block 19. The terminal block 19 has limit protrusions on both sides, which can fully limit the offset of the connection joint and ensure the strength of the connection structure. At this time, the operator can start the device through the button on the control module 18, judge the overall working effect, and thus facilitate position debugging and control.

[0025] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
