Description

Technical Field

[0001] This application relates to the field of chassis heat dissipation technology, and in particular to a liquid-cooled chassis structure. Background Technology

[0002] During the operation of electronic equipment, the electronic components inside the chassis generate a lot of heat. If the heat cannot be dissipated in a timely and effective manner, it will lead to a decline in the performance of the electronic components, a shortened lifespan, or even equipment failure.

[0003] In existing technologies, chassis heat dissipation has always been a critical factor affecting the stable operation of equipment. Traditional chassis mostly rely on air cooling, which uses fans inside the chassis to circulate air and remove heat. However, with the increasing integration of devices within the chassis, their heat generation has also increased dramatically, making simple air cooling insufficient for efficient heat dissipation. This limitation is particularly pronounced in applications with stringent temperature control requirements, easily leading to excessively high chassis temperatures, which in turn affects equipment performance and lifespan. Therefore, improving chassis heat dissipation efficiency and ensuring the stable operation of devices within the chassis has become an urgent technical problem to be solved. Utility Model Content

[0004] In order to improve the heat dissipation efficiency of the chassis and ensure the stable operation of the equipment inside the chassis, this application provides a liquid-cooled chassis structure.

[0005] The liquid-cooled chassis structure provided in this application adopts the following technical solution: A liquid-cooled chassis structure includes a chassis body, a base plate disposed on the chassis body, and a plurality of cooling plates disposed on the base plate at intervals. Each cooling plate has a first flow channel for flowing cooling water. The base plate has a second flow channel sequentially connecting the flow channels of each cooling plate. The base plate has an inlet end and an outlet end corresponding to the second flow channel. A chiller is disposed on the chassis body, connected to the inlet end and the outlet end, and drives the cooling water through the second flow channel and sequentially through the first flow channels of each cooling plate. A gap is left between each of the cooling plates to allow air circulation. A fan is installed on the housing to drive airflow through the gaps between the cooling plates and transfer heat to the cooling water flowing inside the cooling plates.

[0006] By adopting the above technical solution, spaced cooling plates are set on the chassis base plate, and a first flow channel is set inside the cooling plate. A second flow channel is set on the base plate to connect each first flow channel and is connected to a chiller, so that cooling water flows through each cooling plate in sequence to remove heat. The first flow channel is set inside the cooling plate, which increases the contact area with the hot airflow and improves the heat transfer efficiency between the hot airflow and the cooling water. A fan is set to drive the airflow between adjacent cooling plates, so that the hot airflow and the cooling water can fully contact each other and transfer heat to the cooling water, effectively improving the heat dissipation efficiency of the chassis and ensuring the stable operation of the equipment in the chassis.

[0007] Optionally, a cover plate is provided on one side of the substrate, and the cover plate and several cooling plates form several air guide channels. The fan is installed on the cover plate and is located at the air inlet of the air guide channel. The air outlet of the air guide channel is located inside the housing.

[0008] By adopting the above technical solution, a cover plate and a cooling plate are set on one side of the substrate to form an air guide channel. The fan is installed on the cover plate and is connected to the air inlet of the air guide channel. The air outlet is located inside the box, which can guide the airflow to flow in a specific direction, so that the airflow can contact the cooling plate more concentratedly, enhance the heat exchange effect, and further improve the heat dissipation efficiency.

[0009] Optionally, the housing is provided with a ventilation opening, and a baffle for closing the ventilation opening is rotatably connected to the housing. The baffle can be flipped to open the ventilation opening, and the air outlet of the air guide channel is connected to the ventilation opening through the baffle. The housing is provided with a limiting component for restricting the flipping of the baffle.

[0010] By adopting the above technical solution, the enclosure is equipped with ventilation openings and a flip-up baffle. The ventilation openings are opened by flipping the baffle and connecting to the air outlet of the air guide channel. At the same time, a limiting component is set up so that the opening and closing of the ventilation openings can be flexibly controlled according to actual needs, realizing the switching of different heat dissipation modes and meeting the heat dissipation requirements of the chassis under different operating conditions.

[0011] Optionally, the limiting component includes a limiting pin slidably disposed on the baffle, and the outer wall of the housing is provided with a first limiting groove and a second limiting groove for cooperating with the limiting pin. When the limiting pin is inserted into the first limiting groove, the vent is closed, and the air outlet of the air guide channel is connected to the housing; when the limiting pin is inserted into the second limiting groove, the vent is opened, and the air outlet of the air guide channel is connected to the vent.

[0012] By adopting the above technical solution, the limiting component slides on the baffle to set the limiting pin, and the outer wall and inner wall of the box are provided with the first limiting groove and the second limiting groove. When the limiting pin is inserted into different limiting grooves, different states of the ventilation opening and different connection methods of the air outlet of the air guide channel are realized, which can accurately control the opening and closing of the ventilation opening and the airflow direction, and ensure the stable and reliable operation of the heat dissipation system.

[0013] Optionally, a spring is connected between the baffle and the limiting pin, and the spring drives the limiting pin to tend to insert into the first limiting groove or the second limiting groove.

[0014] By adopting the above technical solution, a spring is connected between the baffle and the limiting pin. The spring drives the limiting pin to tend to insert into the first limiting groove or the second limiting groove, so that the limiting pin maintains a stable position when it is not subjected to external force, preventing the limiting pin from shifting due to vibration or other factors, ensuring the stability of the ventilation port status and the air outlet connection method of the air guide channel, and improving the reliability of the entire heat dissipation system.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. The chiller drives the cooling water to flow sequentially through each cooling plate. The first flow channel is set inside the cooling plate, which increases the contact area with the hot airflow and improves the heat transfer efficiency between the hot airflow and the cooling water. A fan is set to drive the airflow between adjacent cooling plates, so that the hot airflow and the cooling water can fully contact each other and transfer heat to the cooling water, effectively improving the heat dissipation efficiency of the chassis and ensuring the stable operation of the equipment inside the chassis. 2. The design of the vents and baffles, along with the coordination of the limiting components, allows users to flexibly adjust the opening and closing of the vents according to actual heat dissipation needs. When the water-cooling system is working normally, the vents are closed, allowing airflow to circulate inside the enclosure. The circulating cooling water absorbs heat from inside the enclosure, achieving a good cooling effect. When the water-cooling system is not working properly, the vents are opened, and the air outlet of the air guide channel is connected to the vents. The fan drives the airflow exchange between the inside and outside of the enclosure, ensuring basic heat dissipation and reducing the possibility of equipment malfunctioning due to excessive temperature inside the enclosure.

[0025] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0026] This application discloses a liquid-cooled chassis structure. For example... Figure 1 and Figure 2 The water-cooled chassis includes a chassis 10, and a base plate 11 is installed on one or more sides of the chassis wall of the chassis 10. The base plate 11 has a flat surface and a certain strength.

[0027] like Figure 3 and Figure 4 A number of cooling plates 12 are spaced apart on the substrate 11. The cooling plates 12 are rectangular flat plates, and their number can be set according to the actual heat dissipation requirements.

[0028] like Figure 4 , Figure 5 as well as Figure 6 Each cooling plate 12 is made of a high-efficiency thermally conductive material. A first flow channel 13 for cooling water flow is provided inside each cooling plate 12, and connectors 14 are provided at both ends of the first flow channel 13. By setting up the cooling plates 12, the contact area between the cooling water and the air is increased, thereby increasing the heat exchange efficiency and improving the heat absorption effect of the cooling water. A second flow channel 15 is provided on the substrate 11 between each cooling plate 12. The second flow channel 15 connects to the connectors 14 on the adjacent cooling plates 12, so that several first flow channels 13 are connected in series to form a complete cooling water circulation channel.

[0029] The second flow channels 15 at both ends of the cooling water circulation channel are respectively provided with an inlet end 16 and an outlet end 17. A chiller 18 is installed on the housing 10, and the chiller 18 is connected to the inlet end 16 and the outlet end 17 through pipes. When the chiller 18 is working, it drives the cooling water to enter the second flow channel 15 from the inlet end 16, then flows through the first flow channel 13 of each cooling plate 12 in sequence, and finally returns to the chiller 18 from the outlet end 17, realizing the circulation of cooling water.

[0030] The chiller 18 employs the principle of compression refrigeration. It mainly consists of a water pump, compressor, condenser, expansion valve, and evaporator (not shown in the diagram as prior art). The water pump drives the circulation of cooling water within the cooling water circulation channel. The compressor compresses the low-temperature, low-pressure refrigerant gas into a high-temperature, high-pressure gas, which is then sent to the condenser. In the condenser, the high-temperature, high-pressure refrigerant gas exchanges heat with the outside air, releasing heat and becoming a high-temperature, high-pressure refrigerant liquid. This high-temperature, high-pressure refrigerant liquid then passes through the expansion valve for throttling and pressure reduction, becoming a low-temperature, low-pressure refrigerant liquid, which enters the evaporator. In the evaporator, the low-temperature, low-pressure refrigerant liquid absorbs heat from the cooling water, evaporating into a low-temperature, low-pressure refrigerant gas, which is then drawn back into the compressor, completing one refrigeration cycle.

[0031] The chiller 18 is connected to the inlet 16 and outlet 17 of the base plate 11 via pipes. The water pump drives the cooling water through the second flow channel 15 and sequentially through the first flow channel 13 of each cooling plate 12, absorbing heat from the air in the housing 10. After absorbing heat, the cooling water exchanges heat with the low-temperature, low-pressure refrigerant liquid in the evaporator during its passage through the chiller 18, thereby cooling the cooling water. It is then pumped back into the cooling water circulation channel to achieve water-cooled cooling.

[0032] A gap is left between each cooling plate 12 to allow airflow, and the gap width is set according to the heat dissipation and airflow requirements. A cover plate 21 is provided on one side of the base plate 11, and the cover plate 21 is fixedly connected to the base plate 11 by bolts. The cover plate 21 and several cooling plates 12 form several air guide channels 22. The air guide channels 22 are elongated, and the two ends of the air guide channels 22 are air inlets 23 and air outlets 24, respectively.

[0033] like Figure 3 and Figure 7A fan 20 is installed on the housing 10, mounted on the cover plate 21, and connected to the air inlet 23 of the air guide channel 22. The air outlet 24 of the air guide channel 22 is located inside the housing 10. When the fan 20 is working, air enters from the air inlet 23 of the air guide channel 22, transferring the heat in the airflow to the cooling water in each cooling plate 12 through heat transfer, thus achieving a cooling effect on the airflow. After being cooled, the airflow returns to the housing 10 from the air outlet 24 after passing through the air guide channel 22, continuing to absorb the heat generated by the electrical components inside the housing 10. This process is repeated to achieve a circulating heat dissipation effect.

[0034] To mitigate the damage to the water cooling circulation effect, which caused the temperature inside the enclosure 10 to become too high.

[0035] like Figure 2 , Figure 3 as well as Figure 7 The enclosure 10 is provided with a rectangular vent 25, the size of which is set according to the heat dissipation requirements. A baffle 26 for closing the vent 25 is rotatably connected to the enclosure 10 at the vent 25 position. The baffle 26 is connected to the enclosure 10 via a hinge and can rotate around the hinge. When the baffle 26 closes the vent 25, the air outlet 24 of the air guide channel 22 connects to the interior of the enclosure 10; when the baffle 26 rotates to open the vent 25, it abuts against the cover plate 21, and under the guiding effect of the baffle 26, the air outlet 24 of the air guide channel 22 connects to the vent 25.

[0036] like Figure 1 and Figure 8 The housing 10 is equipped with a limiting component to restrict the rotation of the baffle 26. The limiting component includes a limiting pin 31 slidably mounted on the baffle 26. The limiting pin 31 is cylindrical and can slide within a groove on the baffle 26. The outer wall of the housing 10 is provided with a first limiting groove 32 and a second limiting groove 33 for engaging with the limiting pin 31. When the limiting pin 31 is inserted into the first limiting groove 32, the vent 25 is closed, and the air outlet 24 of the air guide channel 22 connects to the inside of the housing 10, allowing air to circulate and dissipate heat within the housing 10. When the limiting pin 31 is inserted into the second limiting groove 33, the vent 25 is opened, and the air outlet 24 of the air guide channel 22 connects to the vent 25, allowing air to exit the housing 10 through the vent 25, achieving external air exchange and heat dissipation.

[0037] The baffle 26 is provided with a spring 34 for pushing the limiting pin 31. When the spring 34 is in its natural state, it drives the limiting pin 31 to tend to insert into the first limiting groove 32 or the second limiting groove 33.

[0038] When the vent 25 needs to be closed, push the baffle 26 to align the limiting pin 31 with the first limiting groove 32. Under the action of the spring 34, the limiting pin 31 automatically inserts into the first limiting groove 32, thus reliably closing the vent 25. When the vent 25 needs to be opened, pull the baffle 26 to disengage the limiting pin 31 from the first limiting groove 32, and then flip the baffle 26 to align the limiting pin 31 with the second limiting groove 33. Under the action of the spring 34, the limiting pin 31 automatically inserts into the second limiting groove 33, thus opening and fixing the vent 25.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
