Description

Technical Field

[0001] This utility model relates to the field of switch technology, specifically a spray-cooled switch. Background Technology

[0002] A switch is a device in a communication system that performs information exchange functions, providing more connection ports in a network to connect more computers. Currently, with the rapid development of data center construction, the Ethernet switch market is showing a steady upward trend. In the past, data centers had relatively low power consumption for switches, and air cooling was the primary method for heat dissipation. However, with the development of high-performance computers, the power density of switches has gradually increased, and traditional air cooling can no longer meet current heat dissipation needs. Better heat exchange methods must be sought, and spray cooling is one such new approach.

[0003] Chinese utility model patent application number 202122782977.1 provides a spray-cooled exchanger, which cools the exchanger by combining spray cooling and heat-conducting air cooling, which can significantly improve the cooling efficiency and ensure the stable use of the exchanger. At the same time, the heat of the air in the fixed box is introduced into the branch duct by the heat-conducting plate, and then the fan drives the air to flow, thereby removing the heat on the heat-conducting plate.

[0004] However, during the use of the above equipment, it was found that the air inlet is the channel for outside air to enter the branch duct. Dust carried by the air during the flow will enter along with the air, which can easily cause it to adhere to the heat-conducting plate, hindering the heat exchange between the heat-conducting plate and the air. The heat-conducting plate cannot effectively transfer the heat generated by the switch to the air, resulting in poor air-cooling heat dissipation of the switch. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a spray-cooled exchanger, which solves the problem mentioned in the background technology that dust in the air easily adheres to the heat-conducting plate, hindering heat exchange between the heat-conducting plate and the air.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spray-cooled exchanger includes a storage box, a liquid storage tank on one side of the storage box, a fixed box inside the storage box, an exchanger body installed in the fixed box, a ventilation box on the top of the fixed box, the ventilation box being connected to a main air duct, a heat-conducting plate inside the ventilation box being connected to the exchanger body, a mounting groove at the end of the ventilation box away from the main air duct, a filter element inserted into the mounting groove, the filter element including a frame, a filter screen installed in the frame, the frame being adapted to the mounting groove, an opening at one end of the mounting groove, and a handle at the end of the frame near the opening, the handle being located on the outside of the ventilation box.

[0007] Preferably, a limiting frame is provided above one end of the mounting slot opening, and the inner side of the limiting frame is adapted to the frame.

[0008] Preferably, a limiting block is slidably disposed in the limiting frame, a pull rod is fixedly connected to the top of the limiting block, the pull rod slidably passes through the connecting frame, the connecting frame is fixedly installed above the limiting frame, and the limiting block is connected to the connecting frame by a spring.

[0009] Preferably, the side of the limiting block opposite to the mounting groove is provided with an inclined surface.

[0010] Preferably, the top of the liquid storage tank is equipped with an inlet pipe and a return pipe, the inlet pipe is connected to the nozzle inside the fixed box through an inlet branch pipe, the inlet branch pipe passes through the ventilation box, and the return pipe is connected to the bottom of the fixed box through a return branch pipe.

[0011] Preferably, observation slots are provided on both the front and rear sides of the liquid storage tank, and the observation slots on the front and rear sides of the liquid storage tank correspond to each other.

[0012] This utility model provides a spray-cooled exchanger. It has the following beneficial effects:

[0013] (1) By inserting a filter element into the mounting slot, the filter screen in the filter element can filter the outside air entering the ventilation box, preventing dust in the air from entering, thereby reducing the possibility of dust adhering to the heat-conducting plate.

[0014] (2) This utility model features a frame that fits into the mounting slot and has a handle for easy removal and insertion, facilitating cleaning or replacement of the filter element by staff and improving maintenance convenience and efficiency. The structure, consisting of a limiting frame, limiting block, pull rod, and spring, can limit and fix the filter element inserted into the mounting slot.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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. Example

[0027] Please see Figure 1-5This utility model provides a spray-cooled exchanger, including a storage box 1, a liquid storage tank 2 on one side of the storage box 1, a fixed box 4 inside the storage box 1, an exchanger body 41 installed in the fixed box 4, a ventilation box 31 installed on the top of the fixed box 4, the ventilation box 31 being connected to the main air duct 3, a heat-conducting plate inside the ventilation box 31 being connected to the exchanger body 41, an installation groove 311 at the end of the ventilation box 31 away from the main air duct 3, a filter element 5 inserted into the installation groove 311, the filter element 5 including a frame 51, a filter screen 53 installed in the frame 51, the frame 51 being adapted to the installation groove 311, an opening at one end of the installation groove 311, and a handle 52 on the end of the frame 51 near the opening, the handle 52 being located on the outside of the ventilation box 31;

[0028] A limiting frame 312 is provided above one end of the opening of the mounting slot 311, and the inner side of the limiting frame 312 is adapted to the frame 51.

[0029] A limiting block 316 is slidably installed in the limiting frame 312. A pull rod 314 is fixedly connected to the top of the limiting block 316. The pull rod 314 slidably passes through the connecting frame 313. The connecting frame 313 is fixedly installed above the limiting frame 312. The limiting block 316 is connected to the connecting frame 313 by a spring 315.

[0030] The side of the limiting block 316 that is away from the mounting groove 311 has an inclined surface.

[0031] Specifically, when outside air enters through one end of the ventilation box 31, the filter screen 53 can filter the dust in the air, reduce the amount of dust entering the ventilation box 31, and thus reduce the possibility of dust adhering to the heat-conducting plate.

[0032] The frame 51 is compatible with the mounting slot 311, and a handle 52 is provided on the end of the frame 51 near the opening. The handle 52 is located on the outside of the ventilation box 31, which makes it convenient for the staff to pull the filter element 5 out of the mounting slot 311 through the handle 52, so as to facilitate the regular cleaning or replacement of the filter screen 53 and ensure the filtration effect.

[0033] When the filter element 5 is inserted into the mounting slot 311, the frame 51 moves along the inclined surface of the limiting block 316 and presses the limiting block 316 through the inclined surface, causing the limiting block 316 to compress the spring 315. When the frame 51 is fully inserted into the mounting slot 311, the limiting block 316 loses the pressure of the frame 51, and then the limiting block 316 is stuck at one end of the frame 51 under the action of the spring 315, limiting the filter element 5 and preventing it from shaking or falling off during the ventilation process, ensuring that the filter element 5 can stably perform its filtering function.

[0034] When it is necessary to disassemble the filter element 5, the staff pulls the lever 314, which causes the lever 314 to move the limiting block 316 and compress the spring 315 at the same time, releasing the limitation block 316 from the frame 51, making it easier to remove the frame 51 from the mounting slot 311, and thus making it easier to clean or replace the filter screen 53 later.

[0035] Furthermore, for implementing spraying on the switch, please refer to [link / reference]. Figures 1-5 The top of the liquid storage tank 2 is equipped with an inlet pipe 22 and a return pipe 23. The inlet pipe 22 is connected to the nozzle inside the fixed box 4 through an inlet branch pipe 221. The inlet branch pipe 221 passes through the ventilation box 31. The return pipe 23 is connected to the bottom of the fixed box 4 through a return branch pipe 231.

[0036] The liquid storage tank 2 is provided with observation troughs 21 on both the front and rear sides, and the observation troughs 21 on the front and rear sides of the liquid storage tank 2 correspond to each other.

[0037] Specifically, the storage tank 2 is used to store the liquid for spraying. The inlet pipe 22 is installed on the top of the storage tank 2 and is connected to the nozzle inside the fixed box 4 through the inlet branch pipe 221. When spraying is required, the liquid in the storage tank 2 flows through the inlet pipe 22 and the inlet branch pipe 221 to the nozzle inside the fixed box 4 under the action of the pump. The liquid is evenly sprayed onto the switch body 41 inside the fixed box 4 through the nozzle, thereby achieving spray cooling of the switch body 41. After spraying, the liquid flows back to the storage tank 2 from the bottom of the fixed box 4 through the return branch pipe 231 and the return pipe 23, forming a cycle.

[0038] The front and rear sides of the liquid storage tank 2 are equipped with corresponding observation tanks 21. The staff can easily observe the liquid level, color and other conditions of the liquid in the liquid storage tank 2 through the observation tanks 21, and promptly detect problems such as insufficient liquid or contamination, so as to take corresponding measures in time to ensure the normal operation of the spray system.

[0039] Working principle: The filter element 5 is inserted into the mounting groove 311 of the ventilation box 31 through the handle 52. At this time, the frame 51 moves along the inclined surface of the limiting block 316 and squeezes the limiting block 316, so that the limiting block 316 compresses the spring 315. When the frame 51 is fully inserted into the mounting groove 311, the limiting block 316 is stuck at one end of the frame 51 under the action of the spring 315, thus completing the installation and fixing of the filter element 5.

[0040] Start the switch and simultaneously control the fan of the main air duct 3 to rotate, causing outside air to pass through the ventilation box 31. When outside air enters through one end of the ventilation box 31, the filter screen 53 filters the dust in the air, reducing the amount of dust entering the ventilation box 31 and reducing the possibility of dust adhering to the heat-conducting plate connected to the switch body 41, thereby ensuring the heat exchange effect between the heat-conducting plate and the air, and realizing ventilation and heat dissipation of the switch body 41.

[0041] When the switch body 41 needs to be spray-cooled, the pump is turned on. The liquid in the storage tank 2 flows through the inlet pipe 22 and the inlet branch pipe 221 to the nozzle in the fixed box 4 under the action of the pump. The liquid is evenly sprayed onto the switch body 41 through the nozzle to achieve spray-cooling of the switch body 41. After spraying, the liquid flows back to the storage tank 2 from the bottom of the fixed box 4 through the return branch pipe 231 and the return pipe 23 to form a circulating cooling.

[0042] Regularly observe the filtration effect of filter screen 53. When it is necessary to clean or replace filter screen 53, the staff pulls the lever 314, which moves the limit block 316 and compresses the spring 315, releasing the limit block 316 from the frame 51. Then, the filter element 5 is pulled out from the mounting slot 311 through the handle 52 for cleaning or replacement. After cleaning or replacement, the filter element 5 is inserted back into the mounting slot 311. The liquid level, color and other conditions of the liquid in the liquid storage tank 2 are observed through the observation slots 21 on the front and rear sides of the liquid storage tank 2. Problems such as insufficient liquid or contamination can be detected in time so as to replenish the liquid or treat the liquid in time to ensure the normal operation of the spray system.
