[0056] The following description, with reference to the accompanying drawings, illustrates various embodiments of the present invention. For clarity, numerous practical details will be described in conjunction with the accompanying drawings. However, it should be understood that these practical details are not intended to limit the invention. That is, in some embodiments of the invention, these practical details are not essential. Furthermore, for the sake of simplicity, some conventionally used structures and components will be shown in the drawings in a simple schematic manner, and in all drawings, the same reference numerals will be used to denote the same or similar components. And, where feasible, features of different embodiments can be applied interchangeably.
[0057] Unless otherwise defined, all terms used herein (including technical and scientific terms) have their ordinary meanings, which are understandable to those skilled in the art. Furthermore, the definitions of the foregoing terms in commonly used dictionaries should be interpreted in the context of this specification as having the meaning consistent with the relevant field of this invention. Unless specifically defined, these terms will not be construed as having idealized or overly formal meanings.
[0058] Please refer to Figure 1 . Figure 1 This is a schematic cross-sectional view of an immersion cooling system 100 according to an embodiment of the present invention. In this embodiment, as... Figure 1As shown, the immersion cooling system 100 includes a housing 110, a first condenser 120, a cover 130, a second condenser 140, and a connecting pipe 150. The housing 110 has a first space S1 configured to contain coolant CL, allowing at least one electronic device 200 to be immersed therein. When the electronic device 200 operates, it generates heat, which evaporates a portion of the coolant CL to form vapor CV. The heated vapor CV rises and leaves the coolant CL. The first condenser 120 is disposed within the housing 110 and configured to condense the vapor CV in the first space S1, thereby restoring the vapor CV to liquid coolant CL. In this way, the coolant CL forms a fluid circulation within the first space S1 of the housing 110 through repeated liquid-gas transitions.
[0059] Furthermore, the cover 130 is disposed outside the housing 110 and together with the outer surface of the housing 110 forms a second space S2. As described above, when the electronic device 200 is operating, a portion of the coolant CL, after being heated, forms vapor CV in the first space S1. At this time, if the housing 110 is not well sealed, the vapor CV located in the first space S1 may leak out of the housing 110. However, since the cover 130 is disposed outside the housing 110 and together with the outer surface of the housing 110 forms the second space S2, the vapor CV leaking from the first space S1 of the housing 110 will be collected in the second space S2. The second condenser 140 is disposed in the second space S2 and configured to condense the vapor CV leaking into the second space S2, thereby reducing the vapor CV back to liquid coolant CL. The connecting pipe 150 includes a first end 151 and a second end 152. The first end 151 of the connecting pipe 150 is connected to the second condenser 140, and the second end 152 of the connecting pipe 150 is connected to the first space S1. Therefore, the coolant CL, which has been reduced to a liquid state by the second condenser 140, can enter the first end 151 of the connecting pipe 150, and then flow back to the coolant CL in the first space S1 from the second end 152 of the connecting pipe 150 after passing through the connecting pipe 150.
[0060] In other words, even if the housing 110 experiences a poor seal, the vapor CV leaking from the housing 110 can be collected by the second space S2 formed by the cover 130 and the outer surface of the housing 110. This vapor is then condensed back into liquid coolant CL by the second condenser 140 within the second space S2, and finally flows back to the coolant CL in the first space S1 through the connecting pipe 150. In this way, the immersion cooling system 100 can effectively prevent the loss of coolant CL from the housing 110 due to poor sealing, thus effectively controlling the operating cost of the immersion cooling system 100.
[0061] In this embodiment, the second condenser 140 and the first condenser 120 are separate from each other, meaning that the second condenser 140 and the first condenser 120 operate independently. For example, when the first condenser 120 is operating, the second condenser 140 can be shut down depending on the actual situation. Therefore, the immersion cooling system 100 has good operational flexibility.
[0062] Specifically, such as Figure 1 As shown, the first condenser 120 includes a main body 121, an inlet port 122, and an outlet port 123. The inlet port 122 and the outlet port 123 are connected to the main body 121. The inlet port 122 is configured to allow water W to flow into the main body 121, and the outlet port 123 is configured to allow water W to flow out of the main body 121. As the water W flows through the main body 121, the main body 121 is configured to condense the gas into a liquid, that is, to condense the vapor CV in the first space S1 into a coolant CL.
[0063] Furthermore, such as Figure 1 As shown, the immersion cooling system 100 also includes a one-way valve 170. The one-way valve 170 is disposed on the connecting pipe 150 and configured to restrict the flow direction of the coolant CL within the connecting pipe 150. Specifically, the one-way valve 170 allows the coolant CL to flow from the second condenser 140 to the first space S1, while prohibiting the flow of the coolant CL or the vapor CV formed by the evaporation of the coolant CL from the first space S1 to the second condenser 140.
[0064] Please refer to Figure 2 . Figure 2 To show Figure 1 A magnified view of a portion of area A. In practical applications, such as... Figure 2 As shown, the immersion cooling system 100 also includes a first sealing assembly 160. The first sealing assembly 160 seals between the shroud 130 and the housing 110 to improve the sealing between the shroud 130 and the housing 110, thereby reducing the chance of steam CV leaking from the second space S2 formed by the shroud 130 and the housing 110.
[0065] Please refer to Figures 3-4 . Figure 3 To show Figure 1 A three-dimensional enlarged schematic diagram of the second condenser 140. Figure 4 To show Figure 3 A partially exploded schematic diagram of the second condenser 140. In practical applications, for example, the second condenser 140 can be a water-cooled condenser. Figures 3-4 As shown, the second condenser 140 also includes a body 141, a fan 142, an inlet port 143, and an outlet port 144. The first end 151 of the connecting pipe 150 is connected to the body 141, and the body 141 has at least one first through-hole H1 (see...). Figure 4 The main body 141 is configured to condense gas into liquid, that is, to condense the vapor CV in the second space S2 into coolant CL, and the coolant CL flows back to the first space S1 through the connecting pipe 150. A fan 142 is connected to the main body 141 and configured to draw gas into the main body 141 through the first perforation H1, that is, to draw the vapor CV in the second space S2 into the main body 141 through the first perforation H1. An inlet port 143 is connected to the main body 141 and configured to allow water W to flow into the main body 141. An outlet port 144 is connected to the main body 141 and configured to allow water W to flow out of the main body 141. Through the flow of water W within the main body 141, the main body 141 can condense the vapor CV in the second space S2 into coolant CL.
[0066] Furthermore, the second condenser 140 also includes at least one extension pipe 145. The extension pipe 145 connects to the main body 141 and communicates with the first perforation H1. The extension pipe 145 has a plurality of second perforations H2, which are arranged along the extension direction of the extension pipe 145. When the fan 142 is started, the vapor CV in the second space S2 is drawn into the extension pipe 145 through the second perforations H2, and then into the main body 141 through the first perforation H1, where it is condensed into coolant CL. Through the extension pipe 145 and the second perforations H2 distributed thereon, the vapor CV in the second space S2 can be drawn into the main body 141 more easily. Depending on the actual situation, the number of first perforations H1 and extension pipes 145 may be multiple, but the present invention is not limited thereto.
[0067] Furthermore, the fan 142 is at least partially exposed outside the main body 141. When the vapor CV in the second space S2 is drawn into the main body 141 by the fan 142, the gas drawn in or the vapor CV that is not condensed by the main body 141 is discharged outside the main body 141 by the fan 142.
[0068] In other embodiments, the second condenser 140 may also be a non-water-cooled condenser, such as an air-cooled condenser or a thermoelectric cooler condenser. In these cases, the second condenser 140 does not include an inlet port 143 and an outlet port 144.
[0069] Please refer to Figure 5 . Figure 5 To show Figure 1 A cross-sectional schematic diagram of an immersion cooling system 100, wherein the cover 180 is in an open state. In this embodiment, as... Figure 5 As shown, the housing 110 has an opening OP that connects the first space S1 and the second space S2. The immersion cooling system 100 also includes a cover 180. The cover 180 is pivotally connected to the housing 110 and corresponds to the opening OP, and is configured to rotate relative to the housing 110 to open or close the opening OP. Figure 1 As shown, when the cover 180 closes the opening OP, the cover 180 is positioned between the first space S1 and the second space S2, meaning that the first space S1 and the second space S2 are not connected to each other. Furthermore, for example, as... Figure 5 As shown, when the cover 180 is opened relative to the opening OP for maintenance of the immersion cooling system 100, the first space S1 and the second space S2 are connected to each other. As described above, since the cover 130 is located outside the housing 110 and forms the second space S2 together with the outer surface of the housing 110, the vapor CV leaving the first space S1 through the opening OP of the housing 110 is collected in the second space S2, thus effectively preventing the loss of coolant CL and effectively controlling the operating cost of the immersion cooling system 100.
[0070] Please refer to Figure 6 . Figure 6 To show Figure 1 A magnified view of a portion of area B. In practical applications, such as... Figure 6 As shown, the immersion cooling system 100 also includes a second sealing assembly 190. The second sealing assembly 190 seals between the cover 180 and the housing 110. When the cover 180 closes the opening OP, the second sealing assembly 190 can improve the sealing between the cover 180 and the housing 110, thereby reducing the chance of vapor CV leaking from the first space S1.
[0071] In summary, the technical solution disclosed in the above embodiments of the present invention has at least the following advantages:
[0072] (1) Even if the enclosure is poorly sealed, the vapor leaking from the enclosure can be collected in the second space formed by the enclosure and the enclosure, then condensed back into liquid coolant by the second condenser in the second space, and finally returned to the coolant in the first space through the connecting pipe. In this way, the immersion cooling system can effectively avoid the chance of coolant loss in the enclosure due to poor enclosure sealing, thus effectively controlling the operating cost of the immersion cooling system.
[0073] (2) Since the second condenser and the first condenser operate independently, the immersion cooling system has good operational flexibility.
[0074] (3) When the cover is opened relative to the opening during maintenance of the immersion cooling system, since the cover is set outside the box and forms a second space together with the box, the steam leaving the first space through the opening of the box will be collected in the second space, thus effectively preventing the loss of coolant and effectively controlling the operating cost of the immersion cooling system.
[0075] Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention.
