Description

Technical Field

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

[0002] In recent years, with the rapid development of internet technology and the rise of cloud services, cloud computing, and AI technologies, servers have become increasingly important. The increased computing and storage capabilities of servers have led to increased power consumption and heat generation, making the design of cooling systems particularly critical. Traditional server cooling solutions mainly include air cooling and liquid cooling. Air cooling relies on airflow to remove heat. While it is low-cost, easy to maintain, and technologically mature, it suffers from low cooling efficiency, high noise levels, and high power consumption. Furthermore, the noise can be harmful to human health and cause environmental complaints. Additionally, the open layout makes it easy for dust and moisture to enter, affecting the lifespan of components.

[0003] Liquid cooling, including immersion and cold plate types, offers quiet operation, high cooling efficiency, and low power consumption, but it also has drawbacks. In immersion liquid cooling, the liquid medium can cause swelling and other effects on connectors, printed circuit boards, and components, leading to device failure. It can also affect dielectrics, electrical signals, and electrical performance, and the initial construction and modification costs are high. Cold plate liquid cooling has a complex structure, requiring high design standards and incurring high costs. Its complex fluid piping also poses a risk of leakage, which can be fatal to servers. Furthermore, when traditional air-cooled and cold plate cooling systems operate in air environments, condensation can easily form if the ambient humidity is high and the equipment surface temperature is below the dew point. To prevent condensation from damaging the server, the temperature of the cool air or cooling water needs to be increased, thus affecting heat dissipation efficiency. Utility Model Content

[0031] Optionally, the refrigeration module includes two heat exchangers arranged in a V-shape.

[0032] Compared with the prior art, the technical solution of this utility model embodiment has the following beneficial effects:

[0033] The technical solution of this application divides the cabinet into independent first and second zones. The component to be cooled is located in the second zone, while a cooling module cools the gas in the first zone. An airflow regulation module circulates the gas between the two zones, keeping the entire cooling system relatively sealed. This design avoids the problem of dust and moisture entering the system, which can affect the lifespan of components, common with traditional air cooling. Compared to traditional liquid cooling, this solution provides a simpler cooling system structure, reducing costs and the risk of leakage. Furthermore, efficient heat dissipation through gas circulation reduces noise and power consumption, improving cooling efficiency. Isolating the cooling module from the component ensures that even if the cooling module's piping leaks, it will not affect the component, which will continue to operate normally. This improves the safety and reliability of the component, reduces downtime due to cooling system failures, and ensures continuous and stable operation.

[0034] Furthermore, the vents are located on the partition or formed between the partition and the cabinet wall. This flexible vent configuration can be adjusted according to the actual layout of the cabinet and the heat dissipation requirements, ensuring smooth airflow between the first and second zones. This is conducive to the stable operation of the heat dissipation system and improves the applicability and flexibility of the heat dissipation system.

[0035] Furthermore, the refrigeration module includes multiple layers of refrigeration units spaced apart along the third direction. Under the agitation of the airflow regulating module, the gas passes through the gap between adjacent layers of refrigeration units and enters the second zone. This arrangement of multiple refrigeration units increases the contact area between the gas and the refrigeration units, improves the heat exchange efficiency, and thus enhances the gas cooling effect, further improving the heat dissipation performance of the heat dissipation system.

[0036] Furthermore, the heat dissipation system may also include a compression module to keep the inside of the cabinet under positive pressure. The entire heat dissipation system is in a relatively sealed state, effectively preventing external moisture and dust from entering the cabinet and affecting the normal operation of the components to be cooled.

[0037] Furthermore, the heat dissipation system can also include a drying module. Compared to traditional air-cooled and plate-type cooling systems, the components to be cooled are in an air environment. When the heat dissipation system is running, if the ambient humidity is high and the surface temperature of the components is below the dew point, condensation is likely to form on the surface of the components. To avoid damage to the components from condensation, the temperature of the cold air or cooling water is usually higher than the dew point, which affects the heat dissipation efficiency. In this application, dry gas is continuously supplied into the cabinet, keeping the inside of the cabinet always dry. Since the components to be cooled are always kept in a dry medium atmosphere, there is no condensation problem. Therefore, the temperature of the cooling medium (cooling water and cooling air) can be set without restriction to achieve higher heat transfer efficiency.

[0038] Furthermore, since the components to be cooled are immersed in a dry gas environment, the air circulates back, carrying away the heat generated by the components. The gas has almost no impact on the integrity of high-speed signals, solving the compatibility and signal integrity problems of liquid media in traditional immersion liquid cooling. In addition, dry gas has better permeability than liquid media and can quickly enter the components to be cooled, especially the gaps between complex devices and components. Its excellent fluidity can quickly carry away heat. Moreover, in traditional immersion liquid cooling, if the liquid maintains a high-speed flow, the impact on the devices on the circuit board in the components to be cooled is large, affecting the stability of device operation. This application uses gas medium flow, which has a low density and can maintain a high flow rate, with little impact on the devices.

[0039] Furthermore, by adjusting the flow field of the gas medium inside the cabinet through the airflow regulation module, optimal temperature control can be achieved. This application can precisely control the gas flow field by optimizing the gas circuit design based on the heat generation status of each area of ​​the component to be cooled, ensuring that more cooling gas flows through areas of concentrated heat, guaranteeing a balanced temperature for the component, and comprehensively improving the operational stability and reliability of the component.

[0048] As mentioned in the background section, existing heat dissipation systems for cabinets are complex in structure and have low safety and heat dissipation efficiency.

[0049] To address the aforementioned technical problems, this application provides a heat dissipation system comprising: a cabinet containing a component to be cooled, the cabinet being divided into an independent first zone and a second zone, wherein the component to be cooled is located in the second zone, and the first zone and the second zone are connected via at least one vent; a cooling module disposed in the first zone, the cooling module being used to cool the gas in the first zone; and an airflow regulating module being used to drive the gas to circulate between the first zone and the second zone via the at least one vent.

[0050] The technical solution of this application divides the cabinet into independent first and second zones. The component to be cooled is located in the second zone, while the gas in the first zone is cooled by a cooling module. An airflow regulation module circulates the gas between the two zones. This partitioned design avoids the problem of dust and moisture easily introduced into traditional air-cooled systems, which can affect component lifespan. Compared to traditional liquid cooling, the air-cooled system provided by this implementation is simpler in structure, reduces cost and leakage risk, and achieves efficient heat dissipation through gas circulation, reducing noise and power consumption while improving heat dissipation efficiency. Isolating the cooling module from the component to be cooled ensures that even if there is a leak in the cooling module piping, it will not affect the component to be cooled, which can still operate normally. This improves the safety and reliability of the component, reduces downtime due to cooling system failures, and ensures continuous and stable operation of the component.

[0051] To make the above-mentioned objectives, features and beneficial effects of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0052] Figure 1 This is a schematic diagram of a heat dissipation system 10 according to an embodiment of the present invention.

[0053] refer to Figure 1 The heat dissipation system 10 may include a cabinet 100, in which a component 20 to be cooled may be placed. The cabinet 100 is divided into two independent zones: a first zone 101 and a second zone 102. The component 20 to be cooled is located in the second zone 102. The first zone 101 and the second zone 102 are connected via at least one vent 103. The partition 1 is used to form at least a partial boundary of the vent 103. A cooling module 2 is disposed in the first zone 101 and is used to cool the gas in the first zone 101. An airflow regulating module 3 is used to drive the gas to circulate between the first zone 101 and the second zone 102 via the at least one vent 103.

[0054] Specifically, in some embodiments, the component to be cooled 20 may be a server or a key component within a server, such as a central processing unit (CPU), a graphics processing unit (GPU), or a memory chip. These components generate a large amount of heat during operation. If the heat cannot be dissipated in time, it will cause the component temperature to rise, thereby affecting the server's performance and lifespan, and may even lead to equipment failure.

[0055] Furthermore, the interior of cabinet 100 is divided into two independent zones: a first zone 101 and a second zone 102. This allows the internal environment of cabinet 100 to be configured according to heat dissipation requirements, optimizing airflow and heat dissipation.

[0056] It should be understood that the above mutual independence refers to functional mutual independence, rather than absolute spatial independence.

[0057] Furthermore, the component to be cooled 20 is located in the second zone 102. After being cooled and de-temperatured in the first zone 101, the gas enters the second zone 102 to perform heat dissipation treatment on the component to be cooled 20.

[0058] Furthermore, the first zone 101 and the second zone 102 are connected via at least one vent 103, and the partition 1 is used to form at least a partial boundary of the vent 103. The vent 103 is a channel for gas to circulate between the first zone 101 and the second zone 102. In practical applications, the structural design of the partition 1 determines the position, size, and shape of the vent 103, thereby affecting the gas flow path and efficiency. Therefore, those skilled in the art can ensure smooth gas flow and achieve efficient heat exchange by reasonably setting the vent 103 according to the actual situation.

[0059] Furthermore, the refrigeration module 2 is located in the first zone 101, which can be used as a gas cooling area, providing suitable installation and operating space for the refrigeration module 2.

[0060] In some embodiments, the cooling module 2 is used to cool the gas in the first zone 101. When the airflow regulating module 3 drives the gas into the first zone 101, the cooling module 2 absorbs the heat of the gas through heat exchange, thereby lowering the gas temperature. The cooled gas then enters the second zone 102 to absorb the heat generated by the component 20 to be cooled, thereby achieving a heat dissipation effect.

[0061] Furthermore, the airflow regulating module 3 is used to drive the gas to circulate between the first zone 101 and the second zone 102 via at least one vent 103. The airflow regulating module 3 is the power source of the entire heat dissipation system 10, and by generating airflow, it promotes the orderly flow of gas between the first zone 101 and the second zone 102.

[0062] As described above, under the action of the airflow regulation module 3, gas is drawn from the second zone 102 (the area where the component 20 to be cooled is located) into the first zone 101, cooled by the cooling module 2, and then returns from the first zone 101 to the second zone 102, thus repeating the cycle. During this process, the gas continuously absorbs heat from the component 20 to be cooled and carries the heat to the first zone 101 for release, thereby achieving continuous heat dissipation from the component 20. Compared with traditional air cooling and liquid cooling methods, this gas circulation method has a simpler structure, reduces the risk of leakage, and also reduces noise and power consumption while improving heat dissipation efficiency.

[0063] In some embodiments, the heat dissipation system 10 may further include a partition 1 for dividing the interior of the cabinet 10 into a first zone 101 and a second zone 102, the partition 1 being adapted to form at least a portion of the boundary of the vent 103.

[0064] In some embodiments, the vent 103 may be formed in the partition 1 (e.g., Figure 2 and Figure 4 (Example shown).

[0065] In some embodiments, the ventilation opening 103 may be formed between the partition 1 and the wall of the cabinet 100.

[0066] In some embodiments, continue to refer to Figure 1 The at least one partition 1 includes a first partition 11 along a first direction D1, the opposite sides of the first partition 11 are connected to the two opposite walls of the cabinet 100, and there is a non-zero gap between the two sides of the first partition 11 along a second direction D2 and the wall of the cabinet 100 to form the vent 103, the second direction D2 being perpendicular to the first direction D1.

[0067] Furthermore, the gas flow direction and trajectory between Zone 101 and Zone 102 can be referenced. Figure 1 The direction of the arrow in the image.

[0068] Furthermore, along the third direction D3, the cooling module 2 and the heat dissipation component 20 are disposed on the same side of the first partition 11, and the first direction D1, the second direction D2 and the third direction D3 are perpendicular to each other.

[0069] exist Figure 1 In the illustrated embodiment, the partial boundaries of the first region 101 and the second region 102 may be non-solid. For example, the partial boundaries of the first region 101 and the second region 102 may be formed between the cooling module 2 and the component to be cooled 20.

[0070] In a typical application scenario, the relatively high-temperature gas in the area (second zone 102) where the heat-dissipating component 20 is located is driven by the airflow regulation module 3, enters the first zone 101 through the vent 103, and then reaches the cooling module 2 for cooling. The cooled gas, under the action of the airflow regulation module 3, then directly enters the second zone 102 to dissipate heat from the heat-dissipating component 20. This layout avoids unnecessary bends in the gas flow path within the cabinet 100, thereby reducing the gas flow path length and resistance, and improving the efficiency of gas circulation.

[0071] In some embodiments, the refrigeration module 2 includes multiple layers of refrigeration units 21 spaced apart along the third direction D3, and the gas in the first region 101 passes through the gap between two adjacent layers of the refrigeration units 21 under the drive of the airflow regulating module 3 to enter the second region 102.

[0072] Specifically, refer to Figure 1 The gaps between adjacent cooling units 21 provide channels for gas flow, allowing gas to pass smoothly between the multiple cooling units 21 and ensuring full contact between the gas and the cooling units 21. Furthermore, the arrangement of multiple cooling units 21 significantly increases the contact area between the gas and the cooling module 2. During the process of passing through the gaps between layers, the gas undergoes sufficient heat exchange with each cooling unit 21. Moreover, when the gas, after being cooled by multiple layers, enters the second zone 102, it can quickly absorb the heat emitted by the component 20 to be cooled, thereby significantly improving the cooling effect of the heat dissipation system 10, ensuring that the component 20 can operate in a lower temperature environment, extending its service life, and improving the stability of equipment operation.

[0073] Furthermore, within the first zone 101, the airflow regulating module 3 is used to drive the gas through the cooling module 2 along the second direction D2.

[0074] Figure 2 This is a schematic diagram of another heat dissipation system 10 according to an embodiment of the present invention. Figure 3 yes Figure 2 A schematic diagram of the heat dissipation system 10 from another perspective.

[0075] In some embodiments, combined with Figure 2 and Figure 3 Along the third direction D3, the cooling module 2 and the heat dissipation component 20 are disposed on opposite sides of the first partition 11, and the first direction D1, the second direction D2 and the third direction D3 are perpendicular to each other.

[0076] Specifically, in Figure 2 and Figure 3 In the illustrated embodiment, within the cabinet 100, a first partition 11 physically divides the space in a three-dimensional space constructed based on the first direction D1, the second direction D2, and the third direction D3. The cooling module 2 and the component to be cooled 20 are located on opposite sides of the first partition 11 in the third direction D3, forming two relatively independent yet interconnected regions. The first region 101 (the side where the cooling module 2 is located) mainly undertakes the gas cooling function, while the second region 102 (the side where the component to be cooled 20 is located) is the area for heat generation and initial absorption. This layout clearly delineates different stages of the heat dissipation process.

[0077] Furthermore, the layout on both sides allows the first zone 101 and the second zone 102 to be spatially independent, making the functional division of the two zones clearer. This independence helps reduce mutual interference between different zones. For example, the impact of vibrations, noise, or condensation generated by the cooling module 2 during operation on the heat dissipation component 20 can be minimized. At the same time, it also facilitates separate maintenance and management of different zones. For example, when repairing the cooling module 2, the normal operation of the heat dissipation component 20 will not be affected.

[0078] Furthermore, the refrigeration module 2 may also include multiple layers of refrigeration units 21 spaced apart along the second direction D2. Under the drive of the airflow regulating module 3, the gas in the first zone 101 passes through the gap between adjacent layers of refrigeration units 21. The at least one partition 1 further includes a second partition 12 and a third partition 13 arranged opposite each other along the second direction D2. The first partition 11, the second partition 12, the third partition 13, and the wall of the cabinet 100 together form the first zone 101. The second partition 12 and the third partition 13 are both parallel to the plane defined by the first direction D1 and the third direction D3. Thus, guided by the second partition 12 and the third partition 13, the gas entering the first zone 101 can follow a predetermined flow trajectory, pass through the gap between adjacent layers of refrigeration units 21, and then converge before flowing into the second zone 102.

[0079] In some embodiments, the vent 103 includes an air inlet and an air outlet located on both sides of the first partition 11 along the second direction D2, respectively. The second partition 12 is disposed on the side of the refrigeration module 2 near the air inlet. The second partition 12 is connected to the first partition 11 to guide the gas entering the first zone 101 via the air inlet into the refrigeration unit 21 from the side away from the first partition 11. The third partition 13 is disposed on the side of the refrigeration module 2 near the air outlet of the first zone 101. The third partition 13 is connected to the wall of the cabinet 100 along the third direction D3 to guide the gas into the gap between two adjacent layers of the refrigeration unit 21.

[0080] Specifically, refer to Figure 2The air inlet of the first zone 101 is located above the air outlet of the first zone 101. The second partition 12 is positioned close to the air inlet of the first zone 101, and the second partition 12 closes the opening of the gap between the refrigeration unit 2 and the first partition facing the second direction D2. Therefore, the gas entering the first zone 101 from the air inlet will flow in the opposite direction of the third direction D3 under the guidance of the second partition 12. Furthermore, when the gas flows to the wall of the cabinet 100 facing the opposite direction of the third direction D3, it will flow in the opposite direction of the second direction D2 along the gap between the refrigeration module 2 and the wall of the cabinet 100 under the guidance of the wall.

[0081] Furthermore, the third partition 13 is disposed on the side of the refrigeration module 2 facing the opposite direction of the second direction D2. The third partition 13 seals the gap between the walls of the refrigeration module 2 and the cabinet 100 on the side facing the third direction D3. Guided by the third partition 13, gas can pass through the gap between two adjacent refrigeration units 21 along the third direction D3. Thus, the arrangement and layout of the second partition 12 and the third partition 13 can guide gas to pass through the gap between two adjacent refrigeration units 21 along the third direction D3 for heat exchange, resulting in a simple structure and low cost.

[0082] In some embodiments, each of the cooling units 21 is plate-shaped and arranged parallel to the plane defined by the first direction D1 and the third direction D3.

[0083] In some embodiments, the vent 103 includes an outlet for gas to enter the second zone 102 from the first zone 101. The at least one partition 1 further includes a fourth partition 14, which, together with the wall of the cabinet 100, forms the second zone 102. The fourth partition 14 is disposed on the side of the heat-dissipating component 20 near the outlet. The fourth partition 14 is connected to the first partition 11. The fourth partition 14 is parallel to the plane defined by the first direction D1 and the third direction D3. The fourth partition 14 is used to guide gas from the side of the heat-dissipating component 20 away from the first zone 101 into the heat-dissipating component 20.

[0084] Specifically, the fourth partition 14 closes the opening between the heat-dissipating component 20 and the first partition 11, which faces the opposite direction of the second direction D2, so that the gas entering the second zone 102 flows along the third direction D3 under the guidance of the fourth partition 14. Then, under the combined action of the wall of the cabinet 100 facing the third direction D3, the guided gas blows across the heat-dissipating component 20 in the opposite direction of the third direction D3.

[0085] In some embodiments, a plurality of heat-dissipating components 20 may be placed in the second region 102. The plurality of heat-dissipating components 20 may be arranged at intervals along the second direction D2, and gas may pass through the gap between two adjacent heat-dissipating components 20 in the opposite direction of the third direction D3 to fully dissipate heat from the heat-dissipating components 20 and improve heat dissipation efficiency.

[0087] In some embodiments, combined with Figure 4 and Figure 5 The refrigeration module 2 includes multiple layers of refrigeration units 21 spaced apart along the first direction D1. The gas in the first region 101 passes through the gap between two adjacent layers of refrigeration units 21 under the drive of the airflow regulating module 3. Each layer of refrigeration unit 21 is plate-shaped and is arranged parallel to the plane defined by the second direction D2 and the third direction D3.

[0089] In some embodiments, reference Figure 6 The cabinet 100 includes a first wall 104 and a second wall 105 disposed opposite to each other, and a third wall 106 and a fourth wall 107 connecting the first wall 104 and the second wall 105 and disposed opposite to each other. The at least one partition 1 includes: a fifth partition 15 extending obliquely from the first wall 104 toward the second wall 105 and the fourth wall 107; and a sixth partition 16 connected to the side of the fifth partition 15 away from the first wall 104 and extending toward the fourth wall 107. The first wall 104, the fifth partition 15, the sixth partition 16, and the fourth wall 107 together enclose the first area 101. The vent 103 includes a first vent 1031 formed between the sixth partition 16 and the fourth wall 107, and a second vent 1032 opened on the fifth partition. The gas enters the first area 101 through the first vent 1031 and flows into the second area 102 through the second vent 1032.

[0090] Furthermore, the fifth partition 15 and the sixth partition 16 are joined together to form a V-shaped partition. This allows for a more rational allocation of space inside the cabinet 100 and also enables smoother gas circulation between the first zone 101 and the second zone 102.

[0091] In some embodiments, the airflow regulating module 3 may be disposed in at least one of the first vent 1031 and the second vent 1032. For example, in Figure 6 In the embodiment shown, the airflow regulating module 3 can be disposed at the second vent 1032.

[0092] In a preferred embodiment, within the first region 101, the refrigeration module 2 is perpendicular to the gas flow direction.

[0093] It should be understood that "vertical" in the above embodiments refers to vertical within the allowable error range, rather than absolute vertical.

[0094] In some embodiments, reference Figure 7 The cabinet 100 includes a first section 1001 and a second section 1002. The first section 1001 defines a first area 101, and the second section 1002 defines a second area 102. The first section 1001 and the second section 1002 are connected by a connecting channel 1003. Gas flows from the first area 101 into the second area 102 through the connecting channel 1003 to dissipate heat from the component 20 to be cooled. Thus, the first section 1001 and the second section 1002 further increase the independence of the first area 101 and the second area 102, ensuring that the cooling gas, after being cooled in the first area 101, dissipates heat from the component 20 to be cooled within the second area 102.

[0095] In some embodiments, the first split 1001 and the second split 1002 are respectively provided with openings connecting to the external environment. External gas enters the first zone 101 through the opening of the first split 1001, is cooled by the cooling module 2, and then enters the second zone 102 through the connecting channel 1003 to dissipate heat from the component 20 to be cooled. Furthermore, the gas that has absorbed heat from the component 20 to be cooled is discharged through the opening of the second split 1002.

[0096] In some embodiments, the heat dissipation system 10 may further include an air intake module 4, which is connected to the first zone 101. The air intake module 4 is used to introduce gas into the cabinet 100 to maintain a positive pressure state inside the cabinet 100. This prevents external gas from entering the internal space of the cabinet 100, ensuring that the gas inside the cabinet 100 is dry and clean.

[0097] In some embodiments, the air intake module 4 may include a drying module 41. The drying module 41 can dry the gas entering the cabinet 100 to prevent excessively humid gas from affecting the normal operation of the heat dissipation components 20.

[0098] For example, in Figure 7 and Figure 8 In the embodiment shown, the drying module 41 is disposed at the gas inlet of the first zone 101 and is used to dry the gas entering the first zone 101.

[0099] In some embodiments, the air intake module 4 may include a filter module 42. The filter module 42 is used to filter impurities such as dust in the gas.

[0100] In some embodiments, the air intake module 4 may further include a compression module 43 for compressing the gas entering the cabinet 100, thereby achieving a positive pressure environment inside the cabinet 100. The compression amount (or power) of the compression module 43 can be adapted to the exhaust efficiency of the exhaust port 5, thereby ensuring that the pressure inside the cabinet 100 is always maintained within a stable positive pressure range.

[0101] In practical applications, the compression module 43 can use an air compressor to provide stable compressed gas (with a certain pressure and flow rate). After being dried by the drying module 41 and the filter module 42 to remove impurities and moisture, clean, dry compressed gas with appropriate pressure (humidity less than 1-3%) is obtained. The pressure is adjusted by the pressure regulating valve, and the dried compressed gas is input into the cabinet 100. The compressed gas flows within the cabinet 100, dissipating heat for the heat-dissipating components 20 and carrying away heat to maintain the normal operating temperature.

[0102] In some embodiments, the filter module 42 may be a compressed gas gas-liquid separator. The compressed gas gas-liquid separator mainly utilizes the principles of gravity, centrifugal force, and filtration to separate impurities such as oil droplets and water droplets from the compressed gas, thereby purifying the compressed gas and providing a clean and dry gas source for downstream equipment, protecting the normal operation of the equipment, and improving production quality.

[0103] In some embodiments, the drying module 41 may be a refrigerated dryer, an adsorption dryer, etc., to dry the compressed gas and remove moisture from it. A refrigerated dryer uses a refrigeration system to cool the compressed gas below its dew point temperature, causing the water vapor in it to condense into liquid water and be discharged, thereby drying the compressed gas, reducing its moisture content, and meeting the dryness requirements of compressed gas in industrial production. An adsorption dryer mainly utilizes the moisture adsorption properties of an adsorbent to dry the compressed gas.

[0104] In some embodiments, a refrigerated dryer and an adsorption dryer can be used in series. The refrigerated dryer can be used for preliminary drying to remove most of the moisture and lower the dew point temperature of the compressed gas. Then, the gas can be further dried by the adsorption dryer to obtain a compressed gas with a lower dew point and higher dryness, which meets the process requirements for high gas dryness.

[0105] In some embodiments, continue to refer to Figure 6 The air intake module 4 includes an air storage tank 44 for storing and introducing the gas into the cabinet 100.

[0106] In some embodiments, the gas may be helium, neon, or hydrogen. Alternatively, the gas may be a gas with a high thermal conductivity similar to helium, neon, or hydrogen.

[0107] In some embodiments, such as Figure 6 The cabinet 100 can be in a fully enclosed state, and the gas circulates between the first zone 101 and the second zone 102 under the drive of the airflow regulating module 3.

[0108] In some embodiments, the cabinet 100 is also provided with an exhaust vent 5 on its wall.

[0109] In some embodiments, the vent 5 is equipped with a waterproof and breathable device. This prevents moisture from entering the cabinet 100 and affecting the normal operation of the heat dissipation components 20.

[0110] In some embodiments, the waterproof and breathable device can be made of a waterproof and breathable material treated with a waterproof coating, including sponge or wool felt. The cabinet 100 can be connected to the outside through the waterproof and breathable device. This effectively prevents external moisture or impurities from entering the cabinet 100 and affecting the normal operation of the heat dissipation components 20. Furthermore, the material itself has sound insulation properties, further improving the quietness of the heat dissipation system 10.

[0111] In some embodiments, reference Figure 3 and Figure 5 The cooling module 2 may also include an inlet 22 and an outlet 23. Thus, cooling water can flow through the inlet 22 and outlet 23 in the cooling module 2, quickly removing heat and thereby improving cooling efficiency.

[0112] In some embodiments, the refrigeration module 2 can be a phase change heat exchanger, wherein the cooling medium can be, for example, halogenated hydrocarbons, alkanes, etc.

[0113] In other embodiments, the refrigeration module 2 may also be a liquid-cooled heat exchanger (such as...). Figure 3 and Figure 5 The cooling medium can be water, alcohol, etc.

[0114] In some embodiments, the refrigeration module 2 may be a finned tube heat exchanger, a plate heat exchanger, a shell and tube heat exchanger, or a spiral plate heat exchanger, etc.

[0115] In some embodiments, reference Figure 7 and Figure 8The refrigeration module includes two heat exchangers arranged in a V-shape. This improves the space utilization and cooling effect inside the cabinet 100.

[0116] By adopting the technical solution of this application, the cabinet 100 is divided into an independent first zone 101 and a second zone 102. The component to be cooled 20 is located in the second zone 102. The cooling module 2 cools the gas in the first zone 101, and the airflow regulating module 3 circulates the gas between the two zones. The entire heat dissipation system 10 is in a relatively sealed state. This design avoids the problem of dust and moisture being easily introduced into traditional air-cooled heat dissipation, which affects the lifespan of the components. Compared with traditional liquid cooling methods, the air-cooled heat dissipation system 10 provided by this implementation scheme has a simpler structure, reduces cost and leakage risk, and achieves efficient heat dissipation through gas circulation, reducing noise and power consumption and improving heat dissipation efficiency. By isolating the cooling module 2 from the component to be cooled 20, even if there is a leakage problem in the cooling module 2 pipeline, it will not affect the component to be cooled 20. The component to be cooled 20 can still operate normally, improving the safety and reliability of the component to be cooled 20, reducing downtime caused by heat dissipation system 10 failure, and ensuring the continuous and stable operation of the component to be cooled 20.

[0117] Furthermore, the vent 103 is located on the partition 1 or formed between the partition 1 and the wall of the cabinet 100. This flexible vent 103 setting can be adjusted according to the actual layout of the cabinet 100 and the heat dissipation requirements, ensuring smooth airflow between the first zone 101 and the second zone 102, which is conducive to the stable operation of the heat dissipation system 10 and improves the applicability and flexibility of the heat dissipation system 10.

[0118] Furthermore, the refrigeration module 2 includes multiple layers of refrigeration units 21 spaced apart along the third direction D3. Under the agitation of the airflow regulating module 3, the gas passes through the gap between two adjacent layers of refrigeration units 21 and enters the second zone 102. This arrangement of multiple layers of refrigeration units 21 increases the contact area between the gas and the refrigeration units 21, improves the heat exchange efficiency, thereby making the gas cooling effect better and further enhancing the heat dissipation performance of the heat dissipation system 10.

[0119] Furthermore, the heat dissipation system 10 may also include a compression module 43 to keep the inside of the cabinet 100 under positive pressure. The entire heat dissipation system 10 is in a relatively sealed state, which effectively prevents external moisture and dust and other impurities from entering the cabinet 100 and affecting the normal operation of the components 20 to be dissipated.

[0120] Furthermore, the heat dissipation system 10 may also include a drying module 41. Compared to traditional air-cooled and plate-type cooling systems, the component to be cooled 20 is in an air environment. When the heat dissipation system 10 is running, if the ambient humidity is high and the surface temperature of the component to be cooled 20 is lower than the dew point temperature, condensation is likely to form on the surface of the component to be cooled 20. To avoid damage to the component to be cooled 20 from condensation, the temperature of the cold air or cooling water is usually higher than the dew point, which will affect the heat dissipation efficiency of the component to be cooled 20. In this application, dry gas is continuously supplied into the cabinet 100, keeping the inside of the cabinet 100 in a dry state. Since the component to be cooled 20 is always kept in a dry medium atmosphere, there is no condensation problem. Therefore, the temperature of the cooling medium (cooling water and cooling air) can be set without restriction to achieve a higher heat transfer efficiency.

[0121] Furthermore, since the component to be cooled 20 is immersed in a dry gas environment, the air circulates back, carrying away the heat generated by the component to be cooled 20. The gas has almost no impact on the integrity of high-speed signals, solving the compatibility and signal integrity problems of liquid media in traditional immersion liquid cooling. In addition, dry gas has better permeability than liquid media and can quickly enter the component to be cooled 20, especially in the gaps of complex devices and components. Its excellent fluidity can quickly carry away heat. Moreover, in traditional immersion liquid cooling, if the liquid maintains a high-speed flow, the impact on the devices on the circuit board in the component to be cooled 20 is large, affecting the stability of device operation. This application uses gas medium flow, which has a low density and can maintain a high flow rate, with little impact on the devices.

[0122] Furthermore, by adjusting the flow field of the gas medium inside the cabinet 100 through the airflow adjustment module 3, optimal temperature control can be achieved. This application can precisely control the gas flow field by optimizing the gas circuit design based on the heat generation status of each area of ​​the component 20 to be cooled, ensuring that more cooling gas flows through areas of concentrated heat, guaranteeing a balanced temperature for the component 20 to be cooled, and comprehensively improving the operational stability and reliability of the component 20 to be cooled.

[0123] Furthermore, the exhaust vent 5 is equipped with a waterproof and breathable device, which can effectively prevent external moisture or impurities from entering the cabinet 100 and affecting the normal operation of the heat dissipation component 20 while allowing air to pass through.

[0124] Furthermore, the cabinet 100 is in a relatively sealed state, which effectively reduces the noise transmitted outward when the heat dissipation system 10 is working. In addition, the waterproof and breathable device itself can also be made of sound-insulating material, which can further reduce the noise transmitted outward when the heat dissipation system 10 is working.
