Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment, and more specifically to a liquid cooling system for electronic equipment. Background Art

[0002] For servers, and even other electronic devices, it is generally necessary to dissipate heat from heat-generating components, such as GPUs, CPUs, switches, etc. However, the current air cooling system is too large to be suitable for some electronic devices. The current liquid cooling system is generally smaller in size, especially at the location where the heat-generating components are located, and occupies a smaller volume.

[0003] The utility model inventor has found through research that it is difficult to ensure that the liquid cooling system will not leak during long-term use. If leakage occurs, especially leakage to electronic equipment, it will cause huge losses.

[0008] When the above-mentioned electronic equipment liquid cooling system is applied, the heating surface of the liquid cooling body is placed against the heating element of the electronic equipment. Then the cooling liquid is transported to the liquid cooling body through the multi-pass structure and the liquid guide tube, and then transported out after absorbing heat to take away the heat. If leakage occurs at any of the multi-pass structure, the liquid guide tube and the liquid cooling body or at any of the connection points, it will be collected in advance by the liquid collection device, which can fully avoid the leakage phenomenon. In addition, a window is left at the heating surface, which not only allows the heating surface to be exposed to absorb heat, but also generally does not leak here due to the working requirements of the heating surface itself, so as a whole, leakage can be avoided. In the above-mentioned electronic equipment liquid cooling system, by continuously surrounding the liquid guide tube, the liquid cooling body and the multi-pass structure, the leaked liquid can be effectively collected in all directions, and the time for the electronic equipment to continue to work can be more fully extended after the liquid cooling system leaks. In addition, the window is set at the heating surface to take into account the working characteristics of the heating surface itself. Basically, no leakage will occur, and the heat exchange needs can be guaranteed, while meeting the need to surround possible leakage points. In summary, the electronic equipment liquid cooling system can effectively solve the problem of low safety of liquid leakage in the electronic equipment liquid cooling system.

[0036] In some embodiments, this embodiment provides an electronic device liquid cooling system, which is mainly used to dissipate heat for electronic components 10 of the electronic device. The electronic components 10 may be one or more of the following: GPU (graphics processor), CPU (central processing unit), switch, etc. Specifically, the electronic device liquid cooling system mainly includes a liquid guide tube 1, a liquid cooling body 2, a multi-pass structure 3, and a liquid collection device.

[0037] The liquid cooling body 2 is generally a liquid cooling plate, and of course, in some states, it can also be a block structure. At least one side of the liquid cooling body 2 is a heating surface, which is used to be close to the heat dissipation surface of the electronic component 10 to be dissipated. At this time, the heating surface of the liquid cooling body 2 and the heat dissipation surface of the electronic component 10 are in thermal contact. When the liquid cooling body 2 is a liquid cooling plate, generally one side of the plate surface is the heating surface, and generally the lower side of the liquid cooling plate is the heating surface, which is close to the upper side of the electronic component 10. A liquid cooling cavity 2-4 is formed inside the liquid cooling body 2, and the heat absorbed by the heating surface can be taken away by discharging the liquid in the liquid cooling cavity 2-4. In order to ensure the flow direction of the internal fluid, the liquid cooling cavity 2-4 is generally separated into a winding flow channel by structures such as partitions.

[0038] The multi-pass structure 3 is used for water distribution and / or water collection, and generally includes a water distributor and / or a water collector. In some applications, the multi-pass structure 3 is also called a water distributor and a water collector. The water distributor and the water collector are collectively referred to as water distributors and water collectors, and may include one of the two or both. The multi-pass structure 3 preferably includes both a water distributor and a water collector. It should be noted that, generally speaking, the liquid delivery main pipe for delivering liquid to the multi-pass structure 3, and the liquid return main pipe for returning liquid, are relatively strong, basically will not leak, and may not be completely surrounded by the liquid collection device. The liquid delivery main pipe and the liquid return main pipe are connected to the condensing equipment to cool the liquid returned from the liquid return main pipe, and then send it out to the multi-pass structure 3 through the liquid delivery main pipe. In order to accelerate the flow of the fluid, a pressure pump is generally provided.

[0039] The liquid-cooling body 2 and the multi-pass structure 3 are connected by a liquid guide tube 1, directly or indirectly, to guide liquid between the two. It should be noted that when multiple liquid-cooling bodies 2 are provided, there may be a liquid guide tube 1 with one end connected to a liquid-cooling body 2, and the other end connected to the multi-pass structure 3 through another liquid-cooling body 2. Generally speaking: at least one liquid guide tube 1 is used as a liquid supply tube, one end of which is connected to the water outlet port of the water distributor in the multi-pass structure 3, and the other end is connected to the inlet of the liquid cooling cavity 2-4 of the liquid cooling body 2; at least one liquid guide tube 1 is used as a liquid return tube, one end of which is connected to the water inlet port of the water collector in the multi-pass structure 3, and the other end is connected to the outlet of the liquid cooling cavity 2-4 of the liquid cooling body 2. Of course, in some cases, one or more of the liquid guide tubes 1 can be used for both infusion and liquid return, such as infusion and liquid return in different time periods.

[0040] The liquid collecting device continuously surrounds the multi-channel structure 3, the liquid conduit 1 and the liquid cooling body 2. The multi-channel structure 3, the liquid conduit 1 and the liquid cooling body 2 are all surrounded by the liquid collecting device, and because they are continuously surrounded, the connection between the multi-channel structure 3 and the liquid conduit 1, and the connection between the liquid conduit 1 and the liquid cooling body 2 are all surrounded by the liquid collecting device. The leaked liquid can be collected by the liquid collecting device and will not fall directly on the electronic component 10, so that after the leakage occurs, the electronic device can continue to be used safely for a period of time. The liquid collecting device refers to a device that constrains the corresponding liquid in a specific position, including but not limited to the following two types: one is a liquid storage cavity formed on a shell or other closed structure, which is constrained in the liquid storage cavity; the other is a water absorbent body, which is constrained in the water absorbent body, such as absorbent cotton.

[0041] In addition, the liquid collecting device also needs to have a window 4 to expose the heated surface of the liquid cooling body 2, so that the heated surface of the liquid body can be in close contact with the corresponding electronic component 10. It should be noted that the edge of the window 4 should be in sealed contact with the liquid cooling body 2, and preferably in sealed contact with the one-piece structure of the liquid cooling body 2 with the heated surface, so that the collecting part of the liquid collecting device can surround the connection between the split structures of the liquid cooling body 2 to collect the leaked liquid. The split in the split structure is a relative concept to the one-piece structure in the one-piece structure, and the splits can be welded, bonded, screwed, etc. The size of the window 4 is set according to the heated surface that needs to be exposed.

[0042] In some embodiments, when the above-mentioned electronic equipment liquid cooling system is applied, the heated surface of the liquid cooling body 2 is placed against the heating element of the electronic equipment. Then the cooling liquid is transported to the liquid cooling body through the multi-pass structure 3 and the liquid guide tube 1, and then transported out after absorbing heat to take away the heat. If leakage occurs at any of the multi-pass structure 3, the liquid guide tube 1 and the liquid cooling body 2 or at the connection, it will be collected in advance by the liquid collection device, which can fully avoid the leakage phenomenon. In addition, a window 4 is left at the heated surface, which can not only make the heated surface exposed to absorb heat, but also generally does not leak here due to the working requirements of the heated surface itself, so as a whole, leakage can be avoided. In the above-mentioned electronic equipment liquid cooling system, by continuously surrounding the liquid guide tube 1, the liquid cooling body 2 and the multi-pass structure 3, the leaked liquid can be effectively collected in all directions, and the time for the electronic equipment to continue to work can be more fully extended after the liquid cooling system leaks. In addition, the window 4 is set at the heated surface to take into account the working characteristics of the heated surface itself, which basically does not leak, and can ensure the heat exchange needs, while meeting the need to surround possible leakage points. In summary, the electronic equipment liquid cooling system can effectively solve the problem of low safety of liquid leakage in the electronic equipment liquid cooling system.

[0043] In some instances, generally speaking, it is necessary to notify the user that a leak has occurred before the liquid collection device is saturated, so that the user can handle some operations that are necessary for the upcoming shutdown as soon as possible before the collection is saturated, such as saving and / or backing up data, stopping some programs, etc. Collection saturation means that the liquid collection device can no longer collect, because the collection capacity of a general liquid collection device is limited.

[0044] As for whether the liquid cooling system is leaking, if the liquid collection device can be observed with the naked eye when collecting liquid, then monitoring can be carried out by naked eye observation to detect leakage before the liquid collection device is saturated. For example, if a liquid collection device uses a transparent bag for collection, leakage can be observed with the naked eye.

[0045] However, regardless of whether it can be observed with the naked eye, a detector can be provided to detect whether there is a leakage. Of course, the detector is used to obtain the leakage detection result before the liquid collecting device is saturated, and obtaining the leakage detection result means detecting the leakage. Before obtaining the leakage detection result and the liquid collecting device is saturated, there is still a certain amount of time to allow the user to take corresponding measures. The specific detector can be a liquid detector to detect whether there is liquid. The liquid detector can be laid in the liquid collecting device to indicate the presence of a leak when it is detected that there is liquid in the liquid collecting device. Of course, the detector can also be through the pressure changes in places such as the liquid guide tube 1, the liquid cooling body 2 and the multi-pass structure 3 to determine whether there is a leak. The specific detector detection method can be set accordingly according to specific needs.

[0046] Generally speaking, different detectors are arranged on the liquid guide tube 1, the liquid cooling body 2 and the multi-pass structure 3, respectively, so that the detection results can be obtained as soon as possible. After the liquid cooling system leaks, the user can operate the electronic equipment as long as possible, so as to detect whether the liquid cooling system leaks as early as possible, and / or increase the collection capacity of the liquid collection device. The former can make the detector as close to the leak point as possible, and the latter can increase the capacity of the liquid collection device.

[0047] In some examples, the liquid collection device can be a protective shell, which continuously surrounds the liquid guide tube 1, the liquid cooling body 2 and the multi-pass structure 3. At this time, a collection cavity is formed between the protective shell and the multi-pass structure 3, the liquid guide tube 1 and the liquid cooling body 2, so that when a leak occurs, whether it is spraying or leaking, it will be collected by the shell wall of the protective shell to be confined in the collection cavity, and the collection capacity is set corresponding to the size of the protective shell. It should be noted that the protective shell can be an integrated shell structure, a split shell structure, or a plurality of shell structures assembled together.

[0048] In some instances, a suction device may be provided, and the suction device is used to extract liquid from the collection chamber, and the extracted liquid is separately stored or discharged from the server as waste liquid. The number of suction ports of the suction device and the distribution position relationship may be set as needed, such as suction ports may be provided at each liquid cooling plate and the multi-pass structure 3, and the protective shell portion at the liquid guide tube 1 is connected to the protective shell portion at the liquid cooling plate, so that the leaked liquid can be introduced into the protective shell of the liquid cooling body and / or the protective shell of the multi-pass structure 3, so as to extract liquid from the protective shell of the liquid cooling body and the protective shell of the multi-pass structure 3. The suction device includes a suction pipe and a negative pressure device, and the inlet of the negative pressure device can be divided into a plurality of suction ports through a plurality of multi-pass joints, so as to be able to extend into the protective shells of each liquid cooling plate and the protective shell of the multi-pass structure 3.

[0049] By providing a suction device, when the volume of the collection cavity formed by the protective shell is limited, liquid can be continuously pumped out to avoid saturation of the collection cavity, thereby increasing the time between obtaining the leakage detection result and saturation of the liquid collection device.

[0050] In some embodiments, the liquid cooling body needs to form a liquid cooling cavity 2-4, and fins or other structures need to be arranged in the liquid cooling cavity 2-4 to form a curved flow channel. Although the above-mentioned liquid cooling body can be formed by 3D integrated printing, the cost is relatively high. A liquid cooling body mainly includes a heated plate 2-1 and a cover plate 2-2, and a sealed connection is formed between the cover plate 2-2 and the heated plate 2-1 to form a first sealed connection seam 2-3. The first sealed connection seam 2-3 seals the liquid cooling cavity 2-4 between the cover plate 2-2 and the heated plate 2-1, and the liquid inlet and outlet of the liquid cooling cavity 2-4 are generally opened on the cover plate 2-2. The sealed connection at the first sealed connection seam 2-3 is generally a welding connection, but a sealed connection can also be achieved by a sealing ring, adhesive, etc. Since there is high-pressure liquid in the liquid cooling plate, the first sealed connection seam 2-3 between the cover plate 2-2 and the heated plate 2-1 is likely to leak, that is, the possibility of the first sealed connection seam 2-3 rupturing is much greater than the possibility of the heated plate 2-1 rupturing.

[0051] Based on the above exploration, in some embodiments, the heated plate 2-1 and the window 4 can be sealed and connected to form a second sealed connection seam 5 around the first sealed connection seam 2-3, and the cavity between the first sealed connection seam 2-3 and the second sealed connection seam 5 is partially connected to the collection chamber, and the second sealed connection seam 5 is set so that the liquid leaked from the first sealed connection seam 2-3 can be blocked by the second sealed connection seam 5 to be retained in the collection chamber, effectively avoiding leakage from the window 4. It should be noted that because the first sealed connection seam 2-3 is in working condition for a long time, and the internal liquid is a high-pressure liquid, and the second sealed connection seam 5 is in working condition only when leakage occurs, and the pressure of the leaked liquid is much lower than the internal fluid pressure of the liquid cooling chamber 2-4, the possibility of rupture of the first sealed connection seam 2-3 is much greater than that of the second sealed connection seam 5, and the possibility of rupture of the second sealed connection seam 5 is very low.

[0052] The second sealing connection seam 5 can be sealed by welding, integral molding, sealing ring 9, gluing, etc., but it is not limited to the above methods. The first sealing connection seam 2-3 and the second sealing connection seam 5 can be the same or different. Specifically, they can be set accordingly as needed. In order to facilitate the installation of the protective shell, the second sealing connection seam 5 can be sealed with a sealing ring 9. For example, an annular groove can be provided on the heated plate 2-1 to place the annular sealing ring 9, and it can be placed against the edge of the window 4, and then fixed by screws or bolts facing the window 4 to compress the sealing ring 9 to ensure the reliability of the seal.

[0053] As shown in the attached drawings, the cover plate 2-2 is located inside the window 4, and a gap channel is formed between the edge and the side wall of the window 4, while the heated plate 2-1 is located outside the window 4, and the edges on all sides protrude from the edge of the cover plate 2-2, and are close to and sealed against the outer surface of the window 4, forming the above-mentioned second sealed connection seam 5. When leakage occurs, the fluid leaking from the first sealed connection seam 2-3 at the edge of the cover plate 2-2 flows horizontally, and when it flows to the area between the edge and the side wall of the window 4, because the second sealed connection seam 5 is formed along the edge of the window 4, the fluid is blocked and cannot flow out from here, and then the fluid flows from the gap channel into the collection chamber of the protective shell.

[0054] In some embodiments, the protective shell as described above can be a single structure, such as the protective shell adopts a relatively large box structure, a window 4 is opened at the bottom of the box structure, and a main pipe perforation and / or a suction pipe perforation are opened on the upper part or around the box structure, and the liquid cooling body 2, the liquid guide tube 1 and the multi-pass structure 3 are all located in the box structure. It should be noted that the liquid guide tube 1 and the multi-pass structure 3 can be completely surrounded by the box structure, that is, all are located in the box cavity of the box structure, and the liquid cooling body 2, the heating surface needs to be exposed from the window 4 to be close to the electronic component 10 to be dissipated, and the rest is located in the box structure. As shown in the accompanying drawings, the heated plate 2-1 can be located on the outside of the box structure and sealed and connected along the window 4 to avoid leakage. When a suction device is provided, the suction port can be set at each corner of the box structure, or at the center, to uniformly extract the liquid. By setting a large box structure, it is not only convenient to install, but also convenient for better protection, and more cavities can be formed.

[0055] In some embodiments, considering that a unified protective shell is not only large in size, but also has relatively large interference, it is affected by the actual scene and cannot be well uniformly configured. Based on this, it is considered here that the protective shell includes a first collection box body 6 arranged at the liquid cooling body 2, a protective outer tube 8 sleeved on the liquid guide tube 1, and a second collection box body 7 arranged at the multi-pass structure 3. When multiple liquid cooling bodies 2 are provided, multiple first collection box bodies 6 can be provided, and the first collection box body 6 can be provided with one or more windows 4 to place one or more liquid cooling bodies 2. Correspondingly, one or more liquid guide tubes 1 can be provided in the protective outer tube 8. Correspondingly, a window 4 needs to be provided on the first collection box body 6 to expose the heated surface of the leakage plate, and the second collection box body 7 generally wraps the entire manifold. Of course, in some embodiments, one or all of the first collection box body 6 and the second collection box body 7 can also be a collection bag.

[0056] In some embodiments, the two ends of the protective outer tube 8 are preferably extended into the first collection box body 6 and the second collection box body 7 to reduce the difficulty of setting the protective outer tube 8 between the first collection box body 6 and the second collection box body 7, so as to achieve full protection. In order to prevent the leaked liquid from the protective outer tube 8 from flowing outward along the tube wall, a baffle can be provided, or a sealing ring can be provided between the protective outer tube 8 and the corresponding perforations on the first collection box body 6 and the corresponding perforations on the second collection box body 7.

[0057] In some embodiments, a first collecting box body 6 is provided to collect leaked liquid at the liquid cooling plate, the first collecting box body 6 comprises a trough body 6-1 with an opening facing upward and a first cover 6-2 covering the trough body 6-1 trough mouth, wherein a window 4 is provided at the bottom of the trough body 6-1, and the edges of the heated plate 2-1 therein are sealed with the edges of the window 4, i.e., the above-mentioned second sealed connection seam 5 is formed, and a gap 6-3 is formed between the edges of the cover plate 2-2 and the inner wall of the trough body 6-1, so that liquid leaked at the sealed connection between the heated plate 2-1 and the cover plate 2-2 can pass through the gap 6-3 into the side of the cover plate 2-2 away from the heated plate 2-1, i.e., liquid leaked from the first sealed connection seam 2-3 will not flow out from the edge of the window 4 because it is blocked by the second sealed connection seam 5, but will flow upward into the cavity portion of the trough body 6-1 located on the side of the cover plate 2-2 away from the heated plate 2-1 under the guidance of the above-mentioned gap 6-3. The cavity portion of the trough body 6 - 1 , which is located on the side of the cover plate 2 - 2 away from the heated plate 2 - 1 , can be used as a collecting cavity or as a part of the collecting cavity.

[0058] In some embodiments, the cover plate 2-2 is on a side away from the heated plate 2-1, which is generally the upper side for practical application. On this side, a liquid inlet and outlet penetrating the cover plate 2-2 is generally provided to connect to the liquid cooling chamber 2-4, and a joint is generally provided on the side of the cover plate 2-2 away from the heated plate 2-1 to connect the liquid guide tube 1, and the joint is located in the groove cavity of the groove body 6-1 to be sealed by the first cover 6-2, so that liquid leaking at the joint will also be confined in the groove cavity of the groove body 6-1.

[0059] In some embodiments, considering that the slot of the slot body 6-1 is generally facing upward in actual applications, the first cover and the slot body 6-1 can be sealed and connected, or the first cover 6-2 can simply cover the slot of the slot body 6-1. The mouth wall of the first cover is preferably sleeved on the outside of the slot body 6-1, and of course it can also be inserted into the inside of the slot body 6-1 and sealed in contact with the inner wall of the slot body 6-1.

[0060] The inlet for the catheter 1 can be arranged on the groove body 6-1, or on the first cover 6-2, preferably on the mouth wall of the first cover 6-2. For example, a groove is provided on the mouth wall of the first cover 6-2, so that after the catheter 1 is installed, the first cover 6-2 can be covered on the groove body 6-1, and the groove is stuck on the catheter 1. The first cover 6-2 can be fixed to the groove body 6-1 by screws.

[0061] In some embodiments, a slot body 6-1 of a first collection box body 6 is provided, which can be used as a mounting structure of the liquid cooling body 2. Specifically, the liquid cooling body 2 is mounted on the slot body 6-1 through a connecting structure, and a laterally extending connecting plate is provided on the outside of the slot body 6-1, and a connecting portion for connecting to an electronic device housing is provided on the connecting plate to achieve fixation between the liquid cooling body 2 and the electronic device housing.

[0062] In some embodiments, the above-mentioned tank body 6-1 can be made of plastic parts to reduce the overall weight. Of course, the tank body 6-1 can also be made of metal parts or other high thermal conductivity plastic parts, and the above-mentioned connecting plate is arranged on the tank body 6-1, and the connecting plate covers other low-heat electronic components to dissipate heat from the low-heat electronic components. After the heat is transferred to the connecting plate, the heat is transferred to the liquid cooling body 2 through other structures of the tank body 6-1, thereby achieving heat dissipation.

[0063] In some embodiments, when a suction device is provided, the suction pipe of the suction device can extend into the groove cavity of the groove body 6-1 through the above-mentioned first cover 6-2 or the groove body 6-1. In order to facilitate fixation and ensure the suction effect, a fixed connector can be provided to be fixed on the cover plate 2-2. In order to achieve a better suction effect, the upper side of the cover plate 2-2 can be provided with a groove to better collect liquid for convenient suction. Further, the fixed connector can include a transverse plate, one end of which is located outside the groove and is installed on the cover plate 2-2 by screws, and the other end of the transverse plate is suspended on the groove, and the side of the transverse plate facing the bottom of the groove has a raised cylindrical portion, the raised cylindrical portion goes deep into the groove, and the side of the transverse plate away from the groove has a connecting column to match the suction pipe orifice. The hole in the connecting column runs through the transverse plate and the cylindrical portion to face the bottom of the groove. By extending the cylindrical portion into the groove, the gap between the cylindrical portion and the groove wall can be reduced, and the suction effect can be better guaranteed.

[0064] In some embodiments, one first collection box body 6 may correspond to one liquid-cooling body 2 so that each liquid-cooling body 2 is independently installed and independently fixed on the housing of the electronic device.

[0065] In some embodiments, in order to facilitate installation, a sheet-like detector may be laid on the cover plate 2 - 2 to detect whether there is leakage.

[0066] In some embodiments, a second collection box body 7 is provided to collect leaked liquid at the multi-channel structure 3. The liquid conduit 1 also needs to extend into the second collection box body 7, so the joint between the liquid conduit 1 and the multi-channel structure 3 needs to be located in the second collection box body 7, so that the leaked liquid at the joint is also constrained by the second collection box body 7 in the box cavity.

[0067] The second collecting box body 7 may include a liquid receiving tray 7-1 and a second cover 7-2 covering the upper side of the liquid receiving tray 7-1, and the second cover 7-2 is used to constrain the liquid moving away from the liquid receiving tray 7-1 to the lower side of the second cover 7-2 so as to be received by the liquid receiving tray 7-1. When a suction device is provided, at least one suction port of the suction device may be provided in the liquid receiving tray 7-1.

[0068] In some embodiments, the manifold as a multi-pass structure 3 is significantly larger than the liquid cooling body 2, so the corresponding second collection box 7 will also be relatively large. If the liquid receiving tray 7-1 is placed horizontally, it is difficult to ensure the flatness of the surface of the liquid receiving tray 7-1, and because of the liquid tension problem, it is difficult to pump out the liquid in the liquid receiving tray 7-1 as quickly as possible. Based on this, the surface of the liquid receiving tray 7-1 can be tilted, concave, etc. to collect the liquid, and then a suction port can be set at the collection point.

[0069] For the convenience of manufacturing, the liquid receiving tray 7-1 is preferably tilted so that the liquid on the liquid receiving tray 7-1 is collected at one place, and in order to better avoid the electronic components 10, the side of the liquid receiving tray 7-1 away from the liquid cooling body 2 is preferably tilted downward so that the liquid on the liquid receiving tray 7-1 flows away from the liquid cooling body 2 and then collects on the corresponding side. If a detector for detecting whether there is a liquid leakage is provided, the detector can be located on the side of the liquid receiving tray 7-1 away from the liquid cooling body 2 to detect whether there is liquid at the collection point, and then it can be determined whether there is a leakage.

[0070] In some embodiments, the second cover 7-2 may be provided with a transparent portion for observing the multi-pass structure 3. Of course, the second cover 7-2 may be partially transparent or entirely transparent. The amount of leakage can be better observed through the transparent portion to determine whether emergency treatment is required. The transparent portion may be a transparent glass portion or a transparent acrylic plate portion.

[0071] In some embodiments, the surface of the liquid receiving tray 7-1 may be tilted by gradually reducing the thickness of the liquid receiving tray 7-1 toward one side to achieve the tilted surface. Of course, the liquid receiving tray 7-1 may also be tilted as a whole to make the surface of the liquid receiving tray 7-1 tilted.

[0072] In order to facilitate the tilting of the liquid receiving tray 7-1, a tilting support foot 7-3 can be provided at the lower side of the liquid receiving tray 7-1. Specifically, in order to facilitate installation, support feet 7-3 can be installed on both sides of the liquid receiving tray 7-1, and the support feet 7-3 are used to connect the housing or body of the electronic device. Specifically, the liquid receiving tray 7-1 can have support feet 7-3 along the extension direction of the multi-channel structure 3, and both ends of the liquid receiving tray 7-1 can be tilted and installed on the support feet 7-3 at both ends.

[0073] The support foot 7-3 is preferably an L-shaped plate, the horizontal plate portion of the L-shaped plate is close to the inner side of the housing of the electronic device and can be connected by screws, and the vertical plate portion of the L-shaped plate is provided with a plurality of connecting through holes, which are arranged in a direction away from the liquid cooling body 2, and the distance between the connecting through holes and the horizontal plate portion gradually decreases in the direction away from the liquid cooling body 2, so as to be inclined downward. The L-shaped plates at both ends can be symmetrically arranged so that the inclination degree of both ends is consistent.

[0074] In some embodiments, for the convenience of setting, the liquid receiving plate 7-1 can include a first plate body and two side plates respectively located at the two ends of the first plate body, wherein the first plate body includes a liquid receiving panel portion, a first vertical plate portion and a second vertical plate portion connected in one piece, the first vertical plate portion is located on the side of the liquid receiving panel portion close to the liquid cooling body 2 and is connected in one piece, and the second vertical plate portion is located on the side of the liquid receiving panel portion away from the liquid cooling body 2 and is connected in one piece, and at both ends in the other direction, the side plates on both sides are sealed and connected to the liquid receiving panel portion, the first vertical plate portion and the second vertical plate portion, so that the first vertical plate portion and the second vertical plate portion and the side plates on both sides form a groove wall structure to constrain the liquid on the liquid receiving panel portion. The outer side of the side plate is connected to the above-mentioned support foot 7-3, that is, the vertical plate portion connected to the above-mentioned support foot 7-3. The second cover includes an upper panel portion and a baffle portion connected in one piece, and the upper panel portion is located on the upper side of the liquid receiving panel portion. Generally speaking, the upper panel portion can cover the upper opening portion. In the up and down directions, the projected area of ​​the liquid receiving panel portion is generally larger than the projected area of ​​the multi-pass structure 3 and its joints. The baffle part is connected to the side of the upper panel part close to the liquid cooling body 2, and the baffle part is provided with a slot to be clamped on the liquid guide tube 1 and the main pipe connected from the multi-channel structure 3. The upper panel part can be provided with an openable transparent part.

[0075] In some embodiments, the end of the protective outer tube 8 located in the first collection box body 6 can be arranged to be connected with the inner cavity of the first collection box body 6, so that the fluid in the protective outer tube 8 can flow out from the end of the protective outer tube 8, and after flowing out, it will enter the first collection box body 6 to extend the saturation time of the protective outer tube 8. Of course, when a suction device is provided, the above arrangement can facilitate the suction of the suction device.

[0076] In some embodiments, the protective outer tube 8 can be an integral tube to be directly sleeved on the catheter 1, but this will make the detection band in the protective outer tube 8 inconvenient to install. Based on this, it is preferred that the protective outer tube 8 includes a transparent band rolled into a tubular shape and a self-sealing strip connecting the lateral edges of the transparent band along the extension direction, so that the transparent band is constrained by the self-sealing strip to form a tubular structure. Of course, in addition to the above-mentioned self-sealing strip, the connection of the lateral edges of the transparent band can also be other ways, such as snap-fitting, gluing, etc. It should be noted that since the leaked liquid is generally in a low-pressure state after entering the protective outer tube 8, the connection strength of the above-mentioned connection method can meet the needs. It should be noted that the transparent band can also be a non-transparent band, but the transparent band is easier to observe. Correspondingly, the first cover 6-2 can also be a transparent structure or partially transparent.

[0077] When a detector is provided, a water leakage detection tape is attached to the inner side of the transparent tape along the extending direction of the transparent tape to serve as the above-mentioned detector. At this time, the water leakage detection tape can be provided at the lower side of the liquid guiding tube 1 .

[0078] When the end of the outer tube 8 located in the first collecting box body 6 needs to be protected, it is connected to the inner cavity of the first collecting box body 6. At this time, in the first collecting box body 6, the end of the outer tube 8 is loosely sleeved on the outside of the catheter 1.
