Abstract
Description
Technical Field
[0001] This utility model relates to the field of switch technology, specifically a multi-cavity circulating liquid-cooled switch. Background Technology
[0002] A switch contains many electronic components, such as chips (including CPUs, switching chips, etc.), capacitors, and resistors. These components consume electrical energy during operation, and heat is generated when current flows through resistive components. Taking the CPU in a switch as an example, when it handles a large number of data forwarding and control tasks, the internal transistors constantly switch on and off. During this process, current flows through the transistor channels, and heat is generated due to the resistance of the transistors themselves. Furthermore, as the data processing capacity and transmission speed of the switch increase, the number of transistors inside the chip increases, and the integration becomes more sophisticated, resulting in a corresponding increase in heat generation. When the internal temperature of the switch rises, the performance of the electronic components is affected. For example, the operating frequency of the chip may decrease. This is because the electrical characteristics of components such as transistors inside the chip change in high-temperature environments, leading to increased signal transmission delays. To ensure correct data transmission, the chip may automatically reduce its operating frequency. Just as people feel fatigued and experience decreased work efficiency in high-temperature environments, chips cannot perform at their optimal level under high temperatures.
[0003] Existing technology, such as publication number CN216291289U, provides a network management switch with heat dissipation function, relating to the field of network management switches. This utility model includes a main structure, comprising a housing, a heat dissipation mechanism including a transmission component disposed on one side of the housing and a ventilation component disposed on the other side of the housing. The transmission component is used to draw air into the housing, and the ventilation component is used to expel hot air from the housing. A protective mechanism is mounted on one side of the housing. The transmission component includes a fixed frame disposed inside the housing. A first square hole is provided on one side surface of the housing, and the fixed frame is connected to the first square hole. A support plate is disposed inside the fixed frame. This utility model provides a network management switch with heat dissipation function. A motor drives a rotating shaft to rotate, causing the fan blades to rotate, thereby drawing in surrounding air to create a negative pressure. Fresh air from the outside is drawn into the housing through the first square hole, while hot air from inside the housing is expelled through the mounting frame, thus promptly dissipating heat and cooling the interior of the housing.
[0004] In this solution, hot air is exhausted from the casing through a ventilation assembly. However, external dust and moisture can easily enter the network switch through the ventilation assembly, potentially damaging the internal electronic components. While some solutions use coolant for heat dissipation, the coolant temperature can become too high over time, leading to decreased cooling efficiency. Therefore, we propose a multi-cavity circulating liquid-cooled switch. Utility Model Content
[0005] The purpose of this utility model is to provide a multi-cavity circulating liquid-cooled switch, which solves the problem that when hot air is exhausted from the casing through the ventilation component, external dust and moisture can easily enter the interior of the network switch through the ventilation component, and dust and moisture can easily damage the internal electronic components.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A multi-cavity circulating liquid-cooled exchanger includes an exchanger body, wherein the exchanger body is provided with a cooling mechanism;
[0008] The cooling mechanism includes two hollow heat-absorbing plates, which are respectively embedded in the top and bottom of the switch body housing. A circulation chamber is provided on one side of the switch body, and a partition ring is fixedly connected to the inner wall of the circulation chamber to divide the circulation chamber into an inlet area and an outlet area. One side of each of the two hollow heat-absorbing plates is connected to the inlet area of the circulation chamber through an inlet pipe, and the other side of each of the two hollow heat-absorbing plates is connected to the outlet area of the circulation chamber through a return pipe. A rotating impeller is provided in the outlet area of the circulation chamber.
[0009] Preferably, a motor is embedded in the casing of the switch body at the location of the circulation chamber. The output shaft of the motor is fixedly connected to a first magnetic ring. A second magnetic ring corresponding to the first magnetic ring is rotatably arranged in the water inlet area of the inner wall of the circulation chamber, and the second magnetic ring is fixedly connected to the impeller through a shaft.
[0010] Preferably, the inner wall of the hollow heat absorption plate is provided with a plurality of first heat exchange plates.
[0011] Preferably, each of the first heat exchange plates has a notch, and the notches on adjacent first heat exchange plates are staggered, so that the hollow heat absorption plate has a serpentine water flow channel inside.
[0012] Preferably, a wind shroud is fixedly connected to the outer wall of the circulation chamber, and a third magnetic ring is rotatably connected to the outer wall of the circulation chamber inside the wind shroud. A magnetic block that is magnetically attracted to the third magnetic ring is provided inside the impeller, and a fan blade is fixedly connected to the third magnetic ring.
[0013] Preferably, guide pipes are fixedly connected to both sides of the wind shroud, and the guide pipes are fixedly connected to the return pipes.
[0014] Preferably, a number of second heat exchange plates are fixedly connected to the inner wall of the guide tube, dividing the interior of the guide tube into multiple airflow channels.
[0015] By employing the above technical solution, this utility model provides a multi-cavity circulating liquid-cooled exchanger. It possesses at least the following beneficial effects:
[0016] I. This utility model, through the setting of a cooling mechanism, allows the hollow heat-absorbing plates embedded at the top and bottom of the switch body shell to absorb the heat generated when the switch body generates heat during operation. The heat is then returned to the hollow heat-absorbing plate through the return pipe on the side of the circulation chamber by the centrifugal force generated by the impeller rotation. Due to the discharge of coolant from the outlet area of the circulation chamber, coolant from the inlet area of the circulation chamber flows into the outlet area of the circulation chamber. The inlet area of the circulation chamber draws coolant from the hollow heat-absorbing plate through a connected inlet pipe, thus forming a circulation of coolant. This avoids the problem of local overheating in a static cooling state, which leads to a decrease in heat dissipation efficiency. Furthermore, by setting a first heat exchange plate on the inner wall of the hollow heat-absorbing plate and creating staggered notches on the first heat exchange plate, the coolant flows in a serpentine, meandering trajectory when passing through the hollow heat-absorbing plate. This avoids areas with relatively slow water flow far from the inlet and outlet of the hollow heat-absorbing plate, which could lead to uneven temperature distribution of the coolant. In addition, the first heat exchange plate increases the contact area with the coolant, further improving the heat absorption efficiency of the coolant.
[0017] II. When the impeller of this utility model rotates, the magnetic attraction of the magnetic block inside the impeller pulls the fan blades on the third magnetic ring to rotate and blow air. The airflow blows through the guide pipe. Since the guide pipe is equipped with a second heat exchange plate that can absorb the heat of the coolant inside the return pipe, the airflow can carry away the heat dissipation on the second heat exchange plate when it passes through the guide pipe, so as to facilitate the cooling of the coolant and keep the coolant at a suitable temperature for circulation and heat dissipation.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] A multi-cavity circulating liquid-cooled exchanger, such as Figure 1 - Figure 5 As shown, the device includes a switch body 1, which is equipped with a cooling mechanism 2. The cooling mechanism 2 includes two hollow heat absorption plates 21, which are respectively embedded in the top and bottom of the switch body 1. A circulation chamber 22 is provided on one side of the switch body 1. A partition ring 221 is fixedly connected to the inner wall of the circulation chamber 22 to divide the circulation chamber 22 into an inlet water area and an outlet water area. One side of each of the two hollow heat absorption plates 21 is connected to the inlet water area of the circulation chamber 22 through an inlet water pipe 23. On the other side of the heat absorption plate 21, it is connected to the water outlet area of the circulation chamber 22 through the return pipe 24. A rotating impeller 222 is installed in the water outlet area of the circulation chamber 22. The switch body 1 housing is embedded with a motor 223 in the position of the circulation chamber 22. The output shaft of the motor 223 is fixedly connected to a first magnetic ring 224. The water inlet area of the inner wall of the circulation chamber 22 is rotatably provided with a second magnetic ring 225 corresponding to the first magnetic ring 224, and the second magnetic ring 225 is fixedly connected to the impeller 222 through the rotating shaft.
[0027] In this embodiment, by setting up a cooling mechanism 2, when the switch body 1 generates heat during operation, the hollow heat-absorbing plate 21 embedded at the top and bottom of the switch body 1 housing absorbs the generated heat. The starting motor 223 drives the first magnetic ring 224 to rotate, and the magnetic attraction of the first magnetic ring 224 pulls the impeller 222 on the second magnetic ring 225 to rotate. This causes the coolant in the outlet area of the circulation chamber 22 where the impeller 222 is located to flow back to the hollow heat-absorbing plate 21 from the return pipe 24 on the side of the circulation chamber 22 due to the centrifugal force generated by the rotation of the impeller 222. As the coolant in the outlet area of the circulation chamber 22 is discharged, the coolant in the inlet area of the circulation chamber 22 flows into the outlet area of the circulation chamber 22. The inlet area of the circulation chamber 22 draws the coolant in the hollow heat-absorbing plate 21 through the connected inlet pipe 23, thereby forming a circulation of coolant to avoid the problem of local overheating in the static cooling state leading to a decrease in heat dissipation effect.
[0028] like Figure 5 As shown, preferably, the inner wall of the hollow heat absorption plate 21 is provided with a number of first heat exchange plates 211. Each of the first heat exchange plates 211 has a notch, and the notches on adjacent first heat exchange plates 211 are staggered, so that the hollow heat absorption plate 21 has a serpentine water flow channel inside.
[0029] In this embodiment, by setting a first heat exchange plate 211 on the inner wall of the hollow heat absorption plate 21 and opening staggered notches on the first heat exchange plate 211, the coolant flows in a serpentine path when passing through the hollow heat absorption plate 21. This avoids the situation where there is a relatively slow water flow area far from the inlet and outlet of the hollow heat absorption plate 21, which would lead to uneven temperature distribution of the coolant. In addition, the first heat exchange plate 211 can increase the contact area with the coolant, which can further improve the heat absorption efficiency of the coolant.
[0030] like Figure 3 , Figure 4 As shown, preferably, a fan shroud 25 is fixedly connected to the outer wall of the circulation chamber 22, and a third magnetic ring 251 is rotatably connected to the outer wall of the circulation chamber 22 inside the fan shroud 25. A magnetic block that is magnetically attracted to the third magnetic ring 251 is provided inside the impeller 222. A fan blade 252 is fixedly connected to the third magnetic ring 251. A guide pipe 26 is fixedly connected to both sides of the fan shroud 25, and the guide pipe 26 is fixedly connected to the return pipe 24. Several second heat exchange plates 261 are fixedly connected to the inner wall of the guide pipe 26, dividing the interior of the guide pipe 26 into multiple airflow channels.
[0031] In this embodiment, when the impeller 222 rotates, the magnetic attraction of the magnetic block inside the impeller 222 pulls the fan blade 252 on the third magnetic ring 251 to rotate and blow air. The airflow blows through the guide pipe 26. Since the guide pipe 26 is equipped with a second heat exchange plate 261 that can absorb the heat of the coolant inside the return pipe 24, when the airflow passes through the guide pipe 26, it can carry away the heat dissipation on the second heat exchange plate 261 to facilitate the cooling of the coolant, so that the coolant is always at a suitable temperature for circulating heat dissipation.
[0032] In use, the multi-cavity circulating liquid-cooled exchanger of this utility model generates heat when the exchanger body 1 operates. Hollow heat-absorbing plates 21 embedded at the top and bottom of the exchanger body 1 absorb this heat. A starting motor 223 drives a first magnetic ring 224 to rotate. The magnetic force of the first magnetic ring 224 pulls the impeller 222 on the second magnetic ring 225 to rotate, causing the coolant in the outlet area of the circulation chamber 22 (where the impeller 222 is located) to flow back into the hollow heat-absorbing plate 21 through the return pipe 24 on the side of the circulation chamber 22 due to the centrifugal force generated by the rotation of the impeller 222. The discharge of coolant from the outlet area of the circulation chamber 22 causes coolant in the inlet area of the circulation chamber 22 to flow into the outlet area of the circulation chamber 22. The inlet area of the circulation chamber 22 draws coolant from the hollow heat-absorbing plate 21 through a connected inlet pipe 23, thus forming a coolant circulation. Furthermore, a first heat exchange fin 211 is installed on the inner wall of the hollow heat-absorbing plate 21. The staggered notches on the first heat exchange plate 211 allow the coolant to flow in a serpentine pattern through the hollow heat absorption plate 21. This avoids uneven temperature distribution of the coolant in areas far from the inlet and outlet of the hollow heat absorption plate 21 where the water flow is relatively slow. The first heat exchange plate 211 also increases the contact area with the cooling system, further improving the heat absorption efficiency of the coolant. When the impeller 222 rotates, the magnetic attraction of the magnetic block inside the impeller 222 pulls the fan blade 252 on the third magnetic ring 251 to rotate and blow air. The airflow passes through the guide pipe 26. Since the guide pipe 26 has a second heat exchange plate 261 that can absorb the heat of the coolant inside the return pipe 24, the airflow carries away the heat dissipation from the second heat exchange plate 261 as it passes through the guide pipe 26, facilitating the cooling of the coolant and ensuring that the coolant is always at a suitable temperature for circulation and heat dissipation.
