Description

Technical Field

[0001] This case relates to a cooling system, particularly a cooling cabinet and its fan. By using a modular design for the fan module structure, the maintenance or replacement procedure of the cooling cabinet or fan module is simplified. The necessary positioning, power connection and installation can be performed without tools, effectively reducing replacement time. Background Technology

[0002] Currently, due to the increasing heat generated by electronic components such as CPUs and GPUs within servers, traditional air cooling methods are no longer sufficient. Therefore, liquid cooling is gradually replacing air cooling systems. Cooling cabinets commonly used in data centers typically utilize liquid cooling systems in conjunction with cold plates within the servers for heat dissipation. These cold plates employ a channel structure for heat exchange. The heat generated by the liquid cooling still needs to be further dissipated over a large area through multiple fans and heat exchangers. Therefore, fans can be considered a crucial component in gas-assisted liquid cooling cabinets.

[0003] Generally, gas-assisted liquid cooling cabinets use a large number of fans, which increases the likelihood of failure, thus requiring frequent maintenance and replacement of fan modules. However, current products on the market require additional tools for fan module replacement, resulting in lengthy replacement times and significant labor costs.

[0004] In view of this, it is necessary to provide a cooling cabinet and its fan. By designing a modular fan module structure, the maintenance or replacement procedure of the cooling cabinet or fan module can be simplified. The necessary positioning, power connection and installation can be carried out without tools, which can effectively reduce the replacement time and solve the lack of known technologies. Utility Model Content

[0005] The purpose of this invention is to provide a cooling cabinet and its fan. By using a modular design for the fan module structure, the maintenance or replacement procedure of the cooling cabinet or the fan module can be simplified. The necessary positioning, power connection and installation can be performed without tools, effectively reducing the replacement time.

[0006] Another objective of this invention is to provide a cooling cabinet and its fans. A modular fan module structure allows for simple and quick installation onto multiple mounting bases on the rear panel of the cooling cabinet, relative to the heat exchanger within the cabinet, enabling gas-assisted liquid cooling applications. Each fan module has a pair of handles on the front of its square housing, allowing for easy lifting for installation or removal. Two diagonally opposite recesses on the square housing correspond spatially to the alignment bosses on the mounting bases, facilitating the insertion of the fan module into the corresponding mounting base. Furthermore, a quarter lock engagement element extends from the front housing to the alignment recesses and aligns with the engagement holes on the alignment bosses. When the operator inserts the fan module into the corresponding mounting base using the handles, the operator can then rotate the engagement element (e.g., 90 degrees) or press it down from the front of the square housing to engage or disengage the engagement element with the engagement holes, thereby securely locking the fan module onto or removing it from the mounting base. The alignment recess is formed by case trimming the square housing, allowing for arbitrary chamfer shapes to align with the alignment boss. This prevents damage to the fan module due to incorrect installation orientation when the operator places it into the mounting bracket. Furthermore, the mating of the alignment recess and alignment boss can be achieved through an embedded push-in installation method, making positioning easier. In addition, since the alignment of the alignment recess and alignment boss is completed through an embedded push-in operation, the electrical connection between the fan module and the rack mounting bracket can be designed using quick-connect (blind-mating) terminals. During installation, the operator pushes the fan module into the mounting bracket while holding the handle, and the quick-connect blind-mating connector simultaneously completes the electrical connection, eliminating the need for manual connection of power or signal lines. The male end of the quick-connect terminal is designed to allow for slight movement, preventing damage caused by tolerances. Therefore, multiple modular fan modules on the cooling rack can be installed and removed quickly and easily without the use of tools, making it highly practical for industrial applications.

[0007] To achieve the aforementioned objectives, this application provides a cooling cabinet comprising a cabinet, multiple fan modules, and a heat exchanger. The cabinet includes a rear panel and multiple mounting bases arranged on the rear panel and communicating from the outside of the cabinet to the internal space of the cabinet. Each of the multiple mounting bases includes a square opening, a positioning boss, and a meshing hole. The positioning boss is located at two diagonally opposite corners of the square opening, and the meshing hole is located on the positioning boss. Multiple fan modules are detachably mounted on multiple mounting bases. Each fan module includes a square housing, an alignment recess, and a meshing member. The square housing matches a square opening. The alignment recess is located at two diagonally opposite corners of the square housing, recessed forward from the rear of the housing, and spatially opposite an alignment boss on the mounting base. The meshing member extends through the front of the square housing into the alignment recess. When the alignment recess and alignment boss are aligned, any of the multiple fan modules can be received in a corresponding mounting base along the mating direction. When the alignment recess and alignment boss are engaged, the meshing member can be rotated to engage with a meshing hole to lock the fan module onto the corresponding mounting base. A heat exchanger is housed within a cabinet. When the multiple fan modules are operating, they allow gas to be drawn into the interior space of the cabinet from the rear panel to cool the heat exchanger.

[0008] In one embodiment, the cooling cabinet is a gas-assisted liquid cooling cabinet used in data centers.

[0009] In one embodiment, each of the plurality of fan modules includes a pair of handles, each disposed on the front of the square housing and parallel to the two sides of the square housing.

[0011] In one embodiment, the engaging member is a rotary torsion lock having an engaging tail end, wherein the length of the engaging tail end is less than the length of the engaging hole and greater than the width of the engaging hole.

[0012] In one embodiment, when the alignment recess and alignment boss are aligned and the fan module is accommodated in the corresponding mounting seat along the mating direction, the engaging member rotates to an unlocked position, and the engagement tail end allows the alignment recess and alignment boss to engage through the engagement hole.

[0013] In one embodiment, when the fan module is housed in the corresponding mounting base along the mating direction and the alignment recess engages with the alignment boss, the engaging member rotates from the unlocked position to a locked position, and the engagement tail end and the engagement hole interfere with each other to lock the fan module in the corresponding mounting base.

[0014] In one embodiment, the alignment recess is formed by two opposite chamfers of a square shell.

[0015] In one embodiment, each of the plurality of mounting bases includes a first connector disposed at one corner of a square opening, and each of the plurality of fan modules includes a second connector disposed at the rear of the square housing, the second connector being spatially opposite the first connector, wherein when the fan modules are received in the mounting base along the mating direction, the first connector and the second connector form an electrical connection.

[0016] In one embodiment, the first connector and the second connector are respectively a quick connector male terminal and a quick connector female terminal that are matched with each other.

[0017] To achieve the aforementioned objectives, this application also provides a fan module that can be detachably mounted on a mounting base. The mounting base includes a square opening, a aligning boss, and a meshing hole. The aligning boss is located at two diagonal corners of the square opening, and the meshing hole is located on the aligning boss. The fan module includes a square housing, an aligning recess, and a meshing member. The square housing matches the square opening. The aligning recess is located at two diagonal corners of the square housing, recessed forward from the rear of the square housing, and spatially opposite to the aligning boss of the mounting base. The meshing member extends through the front of the square housing into the aligning recess. When the aligning recess and the aligning boss are aligned, the fan module is allowed to be received within the mounting base along the mating direction. When the aligning recess and the aligning boss are engaged, the meshing member can be rotated to engage with the meshing hole to lock the fan module onto the mounting base.

[0018] In one embodiment, the fan module further includes a pair of handles, respectively disposed on the front of the square housing and parallel to the two sides of the square housing.

[0019] In one embodiment, the docking direction is perpendicular to the front of the square housing, wherein when the fan module is accommodated in the mounting base along the docking direction, the front of the square housing is flush with the square opening of the mounting base.

[0020] In one embodiment, the engaging member is a rotary torsion lock having an engaging tail end, wherein the length of the engaging tail end is less than the length of the engaging hole and greater than the width of the engaging hole.

[0021] In one embodiment, when the alignment recess and alignment boss are aligned, the fan module is allowed to be accommodated in the mounting seat along the docking direction. When the engagement member is rotated to an unlocked position, the engagement tail end allows the alignment recess and alignment boss to engage through the engagement hole.

[0022] In one embodiment, when the fan module is housed in the mounting base along the mating direction and the alignment recess engages with the alignment boss, the engaging member rotates from the unlocked position to the locked position, and the engagement tail end and the engagement hole interfere with each other to lock the fan module in the mounting base.

Figure 5 This is a front view showing the fan module of an embodiment of this case. Figure 6This is a front view showing the mounting base of an embodiment of this invention. This invention provides a gas-assisted liquid cooling cabinet 1 for use in a data center. The cooling cabinet 1 includes a cabinet 3, multiple fan modules 2, and a heat exchanger 4. The cabinet 3 includes a rear panel 30 and multiple mounting bases 31. The multiple mounting bases 31 are arranged on the rear panel 30 and communicate from the outside of the cabinet 3 to the internal space of the cabinet 3. In this embodiment, each of the multiple mounting bases 31 includes a square opening 32, a aligning boss 33, and a meshing hole 34. The aligning bosses 33 are arranged in pairs at the upper right and lower left diagonal corners of the square opening 32, and the meshing holes 34 are arranged in pairs on the aligning bosses 33. The multiple fan modules 2 are detachably disposed correspondingly on the multiple mounting bases 31, and each fan module 2 can be paired and connected with any mounting base 31. In this embodiment, each of the multiple fan modules 2 includes a square housing 21, an aligning recess 23, and a meshing member 24. The square housing 21 matches the square opening 32 of the mounting base 31, and their outlines are similar. Additionally, matching recesses 23 are arranged in pairs at opposite upper right and lower left diagonal corners of the square housing 21. In this embodiment, the matching recesses 23 are also formed by two opposite case trimmings of the square housing 21. The paired matching recesses 23 are recessed forward from the rear of the square housing 21, and spatially relative to the matching boss 33 of the mounting base 31. In this embodiment, the engaging members 24 are arranged in pairs, penetrating through the front face 210 of the square housing 21 into the matching recesses 23. When the alignment recess 23 and the alignment boss 33 are aligned, any one of the multiple fan modules 2 can be accommodated in the corresponding one of the multiple mounting seats 31 along the mating direction (e.g., the reverse X-axis direction). Furthermore, when the alignment recess 23 and the alignment boss 33 are engaged, the rotating engagement member 24 can engage with the engagement hole 34 to lock the fan module 2 onto the corresponding mounting seat 31. In this embodiment, the mating direction is perpendicular to the front face 210 of the square housing 21, and when the fan module 2 is accommodated in the mounting seat 31 along the mating direction, the front face 210 of the square housing 21 is also flush with the square opening 32 of the mounting seat 31. Of course, this embodiment is not limited to this.

[0060] In this embodiment, the heat exchanger 4 is disposed inside the cabinet 3, for example, as a heat exchanger in a gas-assisted liquid cooling system, configured to dissipate the heat generated by the coolant on the cold plate over a large area through multiple fan modules 2 in conjunction with the heat exchanger 4. In this embodiment, when the multiple fan modules 2 are operating, they allow gas to be drawn from the rear side panel 30 into the internal space of the cabinet 3 to cool the heat exchanger 4. Of course, this embodiment is not limited to this.

[0061] In this embodiment, multiple fan modules 2 are modularly designed and have the same structure. The fan body 25 of the fan module 2 is housed within a square housing 21 and is connected front to back. A grille 26 is provided on the front 210 of the square housing 21 to protect the internal fan body 25. Of course, the internal structure of the fan module 2 is not limited to the technical features of this invention and can be adjusted according to actual application needs, which will not be described in detail here. In this embodiment, each of the multiple fan modules 2 also includes a pair of handles 22, which are respectively provided on the front 210 of the square housing 21 and parallel to the two sides of the square housing 21, for example, parallel to the Z-axis direction. With the handles 22, the operator can easily operate the fan module 2 to insert or remove it from the mounting base 31. It should be noted that the multiple fan modules 2 are modular and have the same structure, and can be independently installed and connected to any mounting base 31 for use. In other words, by designing the fan modules 2 modularly, this invention simplifies the maintenance or replacement procedure of the cooling cabinet 1, allowing for tool-free assembly of the required positioning, power connection, and installation, effectively reducing replacement time.

[0062] For ease of explanation, the following describes the positioning, power connection and installation of the single fan module 2 and the mounting base 31, without limiting the scope of this invention. Figure 7 This is a front view showing the fan module of this embodiment housed in the mounting base and the engaging member rotated to the unlocked position. Figure 8 This is a rear view showing the fan module of this embodiment housed in the mounting base with the engaging member rotated to the unlocked position. Figure 9 This is a front view showing the fan module of this embodiment housed in the mounting base and the engaging member rotated to the locked position. Figure 10 This is a rear view showing the fan module of an embodiment of this case housed in the mounting bracket with the engaging member rotated to the locked position. (See reference) Figures 1 to 10 In this embodiment, the engaging member 24 of the fan module 2 is, for example, a quarter lock with an engaging tail end 241. The engaging hole 34 is, for example, a rectangular through hole. The length of the engaging tail end 241 is less than the length of the engaging hole 34, but greater than the width of the engaging hole 34. When the operator wants to install the fan module 2 onto the mounting base 31, the operator holds the handle 22 with both hands, aligning the alignment recess 23 of the fan module 2 with the alignment boss 33 of the mounting base 31. Then, the fan module 2 can be accommodated in the corresponding mounting base 31 along the mating direction (e.g., the reverse X-axis direction). At this time, the engaging member 24 of the fan module 2 needs to be rotated to an unlocked position (e.g., ...). Figure 7As shown), the length direction of the engagement tail end 241 is parallel to the length direction of the engagement hole 34. Since the length of the engagement tail end 241 is less than the length of the engagement hole 34, the fan module 2 can be inserted into the mounting base 31 along the mating direction (e.g., the reverse X-axis direction), while the engagement tail end 241 allows the alignment recess 23 of the fan module 2 to contact and engage with the alignment boss 33 of the mounting base 31 through the engagement hole 34 (e.g., ...). Figure 8 (As shown). Afterwards, the operator can rotate the engaging member 24, for example, 90 degrees, to rotate the engaging member 24 and the engaging tail end 241 from the unlocked position to a locked position (as shown). Figure 9 (As shown). At this time, the engagement tail end 241 of the engagement hole 34 will rotate its length direction to be perpendicular to the length direction of the engagement hole 34. The length of the engagement tail end 241 is greater than the width of the engagement hole 34, so the engagement tail end 241 in the locked position will interfere with the engagement hole 34 (as shown). Figure 10 (As shown) thus locking the fan module 2 into the corresponding mounting bracket 31.

[0063] Conversely, when the operator wants to remove the fan module 2 from the mounting base 31, the operator can rotate the engaging member 24 from the locked position (e.g., Figure 9 (As shown) Rotate to the unlock position (as shown) Figure 7 (As shown). Since the engaging tail end 241 in the unlocked position does not interfere with the engaging hole 34, the operator can hold the handle 22 with both hands and remove the fan module 2 from the mounting base 31 in the opposite direction of the mating (i.e., the X-axis direction). Thus, the operator can easily install multiple fan modules 2 onto multiple mounting bases 31 on the rear panel 30 without using tools to remove the fan modules 2 for replacement or repair, effectively reducing replacement time. It should be noted that the operator can, for example, not limited to, rotate the operating engagement member 24 to rotate the engaging tail end 241. In other embodiments, the operator can also press down on the operating engagement member 24 to change the engaging tail end 241 between the locked and unlocked positions. This application is not limited to this.

[0064] See again Figures 1 to 10 In this embodiment, each modular mounting base 31 further includes a first connector 35 disposed at one corner of the square opening 32 (e.g., Figure 6 As shown), for example, the lower right corner, differs from the two diagonally opposite corners where the alignment boss 33 is located. Each modular fan module 2 also includes a second connector 27 disposed at the rear oblique angle of the square housing 21, such as... Figure 4As shown. In this embodiment, the second connector 27 of the fan module 2 is spatially positioned relative to the first connector 35 of the mounting base 31. In this embodiment, the first connector 35 and the second connector 27 are respectively the male and female quick-connect terminals that mate with each other. When the operator holds the handle 22 and pushes the fan module 2 into the mounting base 31 along the mating direction (i.e., the reverse X-axis direction), the first connector 35 and the second connector 27 can be quickly connected (blindly plugged) to form an electrical connection, eliminating the need for manual connection of power or signal lines. In this embodiment, either the first connector 35 or the second connector 27 can be designed as the male terminal of a quick-connect terminal, allowing for slight movement to further avoid damage caused by tolerances. Thus, multiple modular fan modules 2 on the cooling cabinet 1 can be installed and disassembled simply and quickly without the use of tools.

[0065] It should be further noted that, in the foregoing embodiments, the number and arrangement of the alignment recess 23, alignment boss 33, engaging member 24, engaging hole 34, first connector 35 and second connector 27 may correspond to changes in the size of the square housing 21 and the square opening 32, or be adjusted according to actual application requirements. This case is not limited to this, and will not be elaborated further.

[0066] In summary, this invention provides a cooling cabinet and its fan. Through a modular fan module structure, the maintenance or replacement procedure for the cooling cabinet and fan modules is simplified. Tool-free assembly, positioning, electrical connection, and installation are all possible, effectively reducing replacement time. Multiple modular fan modules can be easily and quickly installed on multiple mounting bases on the rear panel of the cooling cabinet, corresponding to the heat exchanger inside the cabinet, enabling gas-assisted liquid cooling applications. Each fan module has a pair of handles on the front of its square housing, allowing for easy lifting for installation or removal. Alignment recesses are located at two diagonal corners of the square housing, spatially corresponding to alignment bosses on the mounting bases, facilitating the insertion of the fan module into the corresponding mounting base. Furthermore, a rotating torsion lock-type engagement member penetrates the front housing to the alignment recesses and corresponds to the engagement holes on the alignment bosses. When the operator inserts the fan module into the corresponding mounting bracket using the handle, they can then rotate the engaging member (e.g., 90 degrees) or press down on it from the front of the square housing to engage or disengage the engaging member with the engaging hole, thus securely locking the fan module onto or removing it from the mounting bracket. The alignment recess, formed by the chamfered corners of the square housing, allows for any shape of chamfered corners to correspond with the alignment boss, preventing damage to the fan module due to incorrect installation orientation. Furthermore, the mating of the alignment recess and alignment boss can be achieved through an embedded push-in installation method, making positioning easier. In addition, because the alignment of the alignment recess and alignment boss is completed through an embedded push-in operation, the electrical connection between the fan module and the rack mounting bracket can be designed using quick-connect (blind-plug) terminals. During installation, as the operator pushes the fan module into the mounting bracket while holding the handle, the quick-connect blind-plug connector simultaneously completes the electrical connection, eliminating the need for manual connection of power or signal cables. Furthermore, the male end of the quick-connect terminal is designed to allow for slight movement, preventing damage caused by tolerances. As a result, multiple modular fan modules on the cooling cabinet can be easily and quickly installed and removed without tools, making it highly practical for industrial applications.

[0067] This case may be modified in various ways by those skilled in the art, but none of them shall deviate from the scope of protection sought by the appended patent application.
