Description

Technical Field

[0001] The invention relates to the field of switches, and in particular to a hotspot floating Ethernet switch. Background Art

[0002] An Ethernet switch is a network device used in a local area network (LAN) that works at the data link layer (layer 2). Its main function is to receive Ethernet frames from a port and then forward the frames to the corresponding ports based on the destination MAC (media access control) address in the frame, thereby enabling communication between devices connected to different ports.

[0003] At present, Ethernet switches generate a lot of heat when working. The heat generation locations mainly include three parts: the first part is the heat of the battery, the second part is the heat of the chip, and the third part is the heat of the interface. The existing Ethernet switch cooling adopts the built-in fan cooling, but this cooling method cools the entire interior or shell of the Ethernet switch, and cannot cool the heat of the interface in the third part. Therefore, the interface of the Ethernet switch still generates a high temperature. Summary of the invention

[0004] In order to make up for the above shortcomings, the present invention provides a hot spot floating Ethernet switch, which aims to improve the problem of heating of the Ethernet switch interface.

[0005] The present invention is achieved in that:

[0006] The present invention provides a hot spot floating Ethernet switch, comprising a body, an interface member is arranged in the body, both ends of the interface member are fixed with fixed edges, a cooling component is arranged between the two fixed edges, and the interface member is located in the cooling component;

[0007] The cooling component comprises:

[0008] A fixed ring structure, the two ends of which are respectively fixed on the two fixed edges; an air inlet and an air outlet are provided on the fixed ring structure;

[0009] A dynamic ring structure, which rotates on the outer wall of the fixed ring structure, and both ends of the dynamic ring structure are connected with sliding parts, the sliding parts are composed of an externally extending protrusion and an arc-shaped sealing slider, and an arc-shaped sliding cavity for sliding of the arc-shaped sealing slider is provided on the fixed edge, and a brake cavity is formed between the arc-shaped sealing slider and the bottom of the arc-shaped sliding cavity, and the brake cavity is filled with gas that is easily expanded when heated; the dynamic ring structure is also provided with an inlet air channel and an outlet air channel.

[0010] Preferably, the interface component is at least one of a USB interface and an RJ interface.

[0011] Preferably, the fixed edge is an annular structure, and the fixed edge is vertically arranged on the interface member, and a heat conduction member is fixed to the outer wall of the fixed edge, one end of the outer wall of the heat conduction member is in contact with the end of the interface member, and the other end is located in the brake cavity.

[0012] Preferably, the air inlet is located below the interface component, and the air outlet is located above the interface component.

[0013] Preferably, the air inlet is a raised structure arranged at the bottom center of the fixed ring structure, and a Y-shaped airflow channel is arranged in the raised structure, and air outlets at both ends of the airflow channel face the inner bottom wall of the fixed ring structure.

[0014] Preferably, two lower flow guides are fixed to the inner bottom wall of the fixed ring structure, and the lower flow guides are arranged in a U shape, and a flow guide port is formed between the lower flow guides and the inner bottom wall of the fixed ring structure.

[0015] Preferably, two upper flow guides are fixed to the inner top wall of the fixed ring structure, and the exhaust port is located between the two upper flow guides.

[0016] Preferably, the two lower flow guides point to the bottom center of the interface member, and the two upper flow guides point to the top center of the interface member.

[0017] Preferably, a coolant pipe is fixed between two adjacent fixed edges, and an end of the coolant pipe extends into the fixed ring structure.

[0018] Preferably, an airflow duct A and an airflow duct B are fixed between two adjacent fixed edges, the airflow duct A is communicated with the inlet air passage, and the airflow duct B is communicated with the outlet air passage.

[0019] The beneficial effects of the present invention are:

[0020] The present invention sets fixed edges at both ends of the interface part, and senses the temperature of a single interface part through a heat conduction part. When the temperature of the interface part is too high during operation, the dynamic ring structure rotates, causing the air inlet to align with the inlet flow channel, and the exhaust port to align with the outlet flow channel. The inner cavity of the fixed ring structure outside the interface part is connected with the common airflow delivery channel in the same row, and the temperature of the heated interface part is cooled by the circulating airflow. The present invention realizes the connection between a single interface and the overall heat dissipation flow channel through the heat transfer after the single interface part is heated, which is fed back to the single interface part, thereby realizing autonomous heat dissipation of the single interface part in the whole.

[0021] The present invention also realizes the opening or closing of the inner cavity of the fixed ring structure by switching the relative rotation state of the fixed ring structure and the dynamic ring structure, and further realizes the heat dissipation treatment of the outer wall around the interface member in cooperation with the lower guide member and the upper guide member.

[0022] Finally, the present invention also drives the coolant in the fixed ring structure to flow through the airflow. After the coolant absorbs the heat on the outer surface of the interface component, it is transferred to the airflow to accelerate the heat dissipation effect around the interface component.

[0023] In summary, the feedback of a single interface component of the present invention can realize autonomous heat dissipation of the interface component with itself as a "point", thereby alleviating the problem of poor heat dissipation effect of the interface end when the Ethernet switch is in working state in the prior art.

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example

[0038] Reference Figure 1-Figure 9 A hot spot floating Ethernet switch includes a body 1, wherein the body 1 is any Ethernet switch in the prior art, and the main innovation is to reduce the heat dissipation problem of a large number of interface parts in the body 1 of the Ethernet switch, thereby solving the heat dissipation problem of the Ethernet switch.

[0039] Furthermore, an interface component 2 is provided in the body 1. The interface component 2 in the prior art is mainly a USB interface and an RJ45 interface. The USB interface is mainly used to connect to external expansion or external storage of the Ethernet switch, while the RJ45 interface is the access end for connecting the network cable in the Ethernet switch.

[0040] Based on the setting of the interface part 2, in order to solve the heat dissipation problem, firstly, a fixed edge 3 is fixed at both ends of the interface part 2, wherein the fixing method between the interface part 2 and the fixed edge 3 can be screwed. Preferably, the screw passes through the fixed edge 3 and is connected to the interface part 2, so as to ensure the detachable connection between the fixed edge 3 and the interface part 2, which is helpful for the manufacture of the interface part 2 and the fixed edge 3 components, and is convenient for replacement. However, it should be noted that any detachable connection method between the interface part 2 and the fixed edge 3 is acceptable, not limited to screw connection. It should be supplemented that the fixed edge 3 is an annular structure, and the fixed edge 3 is vertically arranged on the interface part 2. In addition, a mounting screw is also installed on the fixed edge 3, and the fixed edge 3 is fixed to the body 1 by the mounting screw, but it is not limited to the fixing method of the mounting screw, and the mounting method such as clamping can also be adopted; finally, a sealing ring is provided on the inner wall of the fixed edge 3 to ensure the sealing of the connection between the fixed edge 3 and the interface part 2.

[0041] Furthermore, a cooling component is provided between the two fixed edges 3, and the interface member 2 is located in the cooling component. Therefore, the interface member 2 is cooled by cooling the outer wall of the interface member 2 through the provision of the cooling component.

[0042] Furthermore, the cooling assembly includes a fixed ring structure 4 and a moving ring structure 5, wherein the moving ring structure 5 rotates on the outer wall of the fixed ring structure 4, and the specific configuration is as follows:

[0043] Reference Figure 4 , Figure 6 and Fig. 9 The two ends of the dynamic ring structure 5 rotate on the two fixed edges 3 respectively, and the rotation method is as follows: both ends of the dynamic ring structure 5 are connected with sliding parts, and the sliding parts are composed of an outwardly extending protrusion 6 and an arc-shaped sealing slider 7. The outwardly extending protrusion 6 provides a spatial basis for the arc-shaped sealing slider 7 to protrude from the end of the dynamic ring structure 5, only to realize the connection structure of the arc-shaped sealing slider 7 and the end of the dynamic ring structure 5 in a staggered setting state; further, the arc-shaped sealing slider 7 has arc surfaces at both ends, and the two arc surfaces are coaxially arranged with the dynamic ring structure 5, that is, to ensure the coaxial rotation of the arc-shaped sealing slider 7 and the dynamic ring structure 5.

[0044] Reference Figure 6 and Figure 8 The fixed edge 3 is provided with an arc-shaped sliding cavity for the arc-shaped sealing slider 7 to slide stably in the fixed edge 3. At the same time, the end of the arc-shaped sliding cavity limits the maximum movement of the arc-shaped sealing slider 7 to ensure that the arc-shaped sealing slider 7 rotates within a specified range. In addition, the side wall of the arc-shaped sliding cavity is also provided with a sliding opening corresponding to the sliding of the externally extending protrusion 6.

[0045] Reference Figure 6 and Figure 8In the present invention, the arc-shaped sealing slider 7 is actuated to rotate, which is actuated by heat changes. Specifically, a brake chamber 8 is formed between the arc-shaped sealing slider 7 and the bottom of the arc-shaped sliding cavity, and the brake chamber 8 is filled with a heat-expandable gas, wherein the heat-expandable gas is any one of H2, O2, N2 and CO2, but not limited to these four gases. When the gas filled in the brake chamber expands after being heated, the arc-shaped sealing slider 7 pushes the dynamic ring structure 5 to rotate, thereby facilitating the subsequent cooling treatment after the airflow circulation. It should be added that: 1. In order to ensure air tightness, a sealing gasket is provided on the outer wall of the arc-shaped sealing slider 7 to prevent leakage of heat-expandable gas. 2. A heat-expandable gas flow channel is provided on the fixed edge 3, which is used to replenish the heat-expandable gas into the brake chamber 8, and a sealing plug is provided at the end of the heat-expandable gas flow channel to ensure sealing.

[0046] Furthermore, in order to ensure the rapidity of heat conduction between the interface member 2 and the heated and easily expanded gas, a heat conducting member 13 is fixed to the outer wall of the fixed edge 3. The outer wall of one end of the heat conducting member 13 fits the end of the interface member 2, and the other end is located in the brake chamber 8. When the interface member 2 is working, its two ends are the last to sense the heat. Therefore, in order to ensure the stability of cooling, the heated and easily expanded gas in the brake chamber 8 senses the temperature of the two ends of the interface member 2, thus ensuring the continuity and accuracy of cooling. The heat at the end of the interface member 2 can be quickly transferred to the brake chamber 8 through the heat conducting member 13, and heat exchange with the heated and easily expanded gas can be achieved. It should be added that the heat conducting member 13 can be made of a material with good heat conduction effect such as metal.

[0047] Based on the arrangement of the fixed ring structure 4 and the dynamic ring structure 5, the arrangement of the airflow channel in the present invention is as follows: the fixed ring structure 4 is provided with an air inlet 9 and an air outlet 10; and the dynamic ring structure 5 is also provided with an air inlet channel 11 and an air outlet channel 12. Specifically, in the initial state, the dynamic ring structure 5 does not rotate relative to the fixed ring structure 4. At this time, the outlet of the air inlet channel 11 is staggered with the inlet of the air inlet 9, and the inlet of the air outlet channel 12 is staggered with the outlet of the air outlet 10; on the contrary, when the dynamic ring structure 5 rotates relative to the fixed ring structure 4, the outlet of the air inlet channel 11 is aligned with the inlet of the air inlet 9, so that the airflow in the air inlet channel 11 flows to the air inlet 9, and then flows to the fixed ring structure 4. In addition, the inlet of the outlet flow duct 12 is arranged in alignment with the outlet of the exhaust port 10, so that the exhaust port 10 discharges the gas in the fixed ring structure 4 to the outlet flow duct 12, avoiding the problem of excessive air pressure in the fixed ring structure 4, and the heat on the outer wall surface of the interface part 2 in the fixed ring structure 4 is taken away by the flowing gas.

[0048] Based on the arrangement of the air inlet 9 and the exhaust port 10, in the present invention, the air inlet 9 is located below the interface member 2, and the exhaust port 10 is located above the interface member 2. Further, after the airflow flows into the air inlet 9, the bottom area of ​​the interface member 2 is cooled, and the flowing airflow passes through the annular guide of the inner wall of the fixed ring structure 4 and flows upward, and is discharged from the exhaust port 10. During the flow of the airflow, the surrounding outer walls of the interface member 2 are heat exchanged in turn, thereby taking away the heat of the surrounding outer walls of the interface member 2, thereby achieving cooling treatment.

[0049] Furthermore, corrugated strips are provided on both sides of the interface member 2, which facilitates airflow to flow from the depression of the corrugated strips to the top of the interface member 2, and the provision of the corrugated strips increases the heat exchange area of ​​the outer wall of the interface member 2, thereby facilitating heat dissipation of the outer wall of the interface member 2.

[0050] In some embodiments, the air inlet 9 is a protruding structure disposed at the bottom center of the fixed ring structure 4, and a Y-shaped air flow channel 14 is disposed in the protruding structure. The air outlets at both ends of the air flow channel 14 face the inner bottom wall of the fixed ring structure 4. The specific direction can be referred to Figure 4 and Fig. 9 .

[0051] Based on the arrangement of the Y-shaped airflow channel 14 , in order to achieve uniform action of the airflow on the outer wall of the interface member 2 , two lower flow guides 15 and two upper flow guides 17 are arranged on the inner wall of the fixed ring structure 4 .

[0052] The two lower guide members 15 are respectively located on both sides of the air inlet 9 and are fixed to the inner bottom wall of the fixed ring structure 4; in addition, the lower guide member 15 is U-shaped, and a guide port 16 is formed between the lower guide member 15 and the inner bottom wall of the fixed ring structure 4. After the airflow encounters the lower guide member 15, the airflow is divided into two parts. One part of the airflow passes through the guide port 16 and flows along the inner wall of the fixed ring structure 4 to the two sides of the interface member 2, and finally flows to the top of the interface member 2; the other part of the airflow is guided by the solid part of the lower guide member 15 and flows to the lower area of ​​the interface member 2.

[0053] The two upper guides 17 are fixed on the inner top wall of the fixed ring structure 4. Then, through the guidance of the upper guides 17, after being blocked by the upper guides 17, the air is guided to the upper surface of the interface member 2. In addition, the exhaust port 10 is located between the two upper guides 17, so that the exhaust port 10 is less affected by the airflow direction after being guided by the upper guides 17, and the smoothness of the exhaust is ensured.

[0054] It should be added that: in order to ensure the uniformity of the airflow on the outer surface of the interface part 2 after the lower guide members 15 and the upper guide members 17 are guided, the two lower guide members 15 point to the bottom center of the interface part 2, and the two upper guide members 17 point to the top center of the interface part 2.

[0055] In addition, to ensure that the air intake and air outlet of the fixed edges 3 in the same row share the same airflow delivery channel, an airflow duct A19 and an airflow duct B20 are fixed between two adjacent fixed edges 3, and the airflow duct A19 is connected to the inlet airflow channel 11. Specifically, the two ends of the airflow duct A19 are connected to the inlet airflow channels 11 on the two fixed edges 3, so the shared inlet airflow delivery channel is the airflow duct A19 and the inlet airflow channel 11 connected in series. The airflow duct B20 is connected to the outlet airflow channel 12. Specifically, the two ends of the airflow duct B20 are connected to the outlet airflow channels 12 on the two fixed edges 3, so the shared outlet airflow delivery channel is the airflow duct B20 and the outlet airflow channel 12 connected in series.

[0056] It should be added that: solenoid valves A are provided at both ends of the airflow duct A19 and the airflow duct B20 in the same row, which are used to control the flow or closure of the common airflow channel. The air inlet end of the airflow duct A19 in the same row is connected to the air outlet end of the Ethernet fan, and the air outlet end of the airflow duct B20 in the same row is connected to the outside world.

[0057] Finally, the present invention further reduces the temperature of the outer wall of the interface member 2, and assists the liquid cooling while cooling the airflow, and quickly cools the interface member 2 under the effect of double cooling. Preferably, the coolant is arranged in the fixed ring structure 4, and when the airflow flows, the coolant is driven to flow along the inner wall of the fixed ring structure 4, thereby contacting the outer wall of the interface member 2, and the temperature of the interface member 2 is transferred to the coolant, and the coolant that absorbs heat continues to flow in the fixed ring structure 4 with the airflow, and the heat in the coolant is transferred to the airflow, thereby realizing the cooling treatment of the coolant. In some embodiments, the structure of the coolant flowing into the fixed ring structure 4 is: a coolant pipe 18 is fixed between two adjacent fixed edges 3, and the end of the coolant pipe 18 extends into the fixed ring structure 4. It should be noted that: multiple interface members 2 in the same row are connected in series through the coolant pipe 18, and when the coolant is injected into one of the fixed ring structures 4, it is transferred to the fixed ring structure 4 in the same row through the coolant pipe 18. In addition, the inlet position of the coolant pipe 18 in the fixed ring structure 4 is at the same height as the outlet position of the coolant pipe 18, so as to ensure that the coolant is transported to the lower fixed ring structure 4 and the amount of coolant contained in each fixed ring structure 4 is the same. And the outlet end position of the air inlet 9 is higher than the liquid level of the coolant to prevent the air flow channel from entering the coolant.

[0058] It should be supplemented that solenoid valves B are provided at both ends of the coolant pipes 18 in the same row to control the flow or closure of the common coolant flow channel.

[0059] The working principle of the hot spot floating Ethernet switch disclosed in the present invention is as follows:

[0060] When the switch is working, after the plugged interface component 2 is heated, the heat conducting component 13 at the end of the interface component 2 transfers heat to the heated and easily expandable gas in the brake chamber 8, causing the heated and easily expandable gas to expand due to the heat. Under the action of air pressure, the sliding component brakes the movable ring structure 5 to rotate, and the movable ring structure 5 rotates, causing the air inlet 9 to align with the inlet flow channel 11, and the exhaust port 10 to align with the outlet flow channel 12. After the airflow is circulated through the common airflow duct A on the interface components 2 in the same row, the air inlet 9 and the exhaust port 10 of the heating interface are connected, thereby generating a flowing airflow in the fixed ring structure 4. Under the guidance of the lower guide member 15 and the upper guide member 17, the airflow cools down the outer wall of the interface component 2.

[0061] In addition, the coolant in the fixed ring structure can be further driven to flow by the airflow. After the coolant absorbs the heat on the outer surface of the interface component 2, it is transferred to the airflow to accelerate the heat dissipation of the interface component 2.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
