Please refer to picture 1. Figure 1 is a schematic cross-sectional view of an immersion cooling system 100 according to an embodiment of the present invention. In this embodiment, as shown in FIG. 1 , the immersion cooling system 100 includes a box 110 , a first condenser 120 , a cover 130 , a second condenser 140 and a connecting pipe 150 . The box 110 has a first space S1 configured to contain the cooling liquid CL so that at least one electronic device 200 can be immersed therein. When the electronic device 200 operates, the electronic device 200 generates heat energy, and the heated electronic device 200 evaporates part of the cooling liquid CL to form steam CV. The heated steam CV rises upward and leaves the cooling liquid CL. The first condenser 120 is disposed in the box 110 and is configured to condense the steam CV in the first space S1, thereby reducing the steam CV into liquid cooling liquid CL. In this way, the coolant CL forms a fluid circulation in the first space S1 of the box 110 through repeated conversion between the liquid state and the gaseous state.

Furthermore, the cover 130 is disposed outside the box 110 and forms the second space S2 together with the outer surface of the box 110 . As mentioned above, when the electronic device 200 is operating, part of the cooling liquid CL forms vapor CV in the first space S1 after being heated. At this time, if the sealing performance of the box 110 is not good, the steam CV located in the first space S1 may leak and leave the box 110 . However, since the cover 130 is disposed outside the box 110 and forms the second space S2 together with the outer surface of the box 110, the steam CV leaking from the first space S1 of the box 110 will be collected in the second space. Within S2. The second condenser 140 is disposed in the second space S2 and is configured to condense the steam CV leaking into the second space S2, thereby reducing the steam CV to the liquid cooling liquid CL. The connecting pipe 150 includes an opposite 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 cooling liquid CL 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 from the second end 152 of the connecting pipe 150 to the first space S1 after passing through the connecting pipe 150. in coolant CL.

That is to say, even if the sealing of the box 110 is not good, the steam CV leaking from the box 110 can be collected by the second space S2 formed by the cover 130 and the outer surface of the box 110, and then pass through the second space S2 The second condenser 140 in the second condenser 140 condenses and returns to the liquid cooling liquid CL, and finally flows back to the cooling liquid CL in the first space S1 through the connecting pipe 150 . In this way, the immersion cooling system 100 can effectively avoid the loss of coolant CL in the box 110 due to poor sealing of the box 110 , so the operating cost of the immersion cooling system 100 can be effectively controlled.

In this embodiment, the second condenser 140 and the first condenser 120 are separated from each other, that is, the second condenser 140 and the first condenser 120 operate independently. That is to say, for example, when the first condenser 120 is operating, the second condenser 140 can stop operating according to actual conditions. Therefore, the immersion cooling system 100 has good operational flexibility.

Specifically, as shown in FIG. 1 , 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 the water W to flow out of the main body 121. With the water W flowing through the main body 121, the main body 121 is configured to condense gas into liquid, that is, condense steam CV in the first space S1 into cooling liquid CL.

Furthermore, as shown in FIG. 1 , the immersion cooling system 100 further includes a one-way valve 170 . The one-way valve 170 is provided on the connecting pipe 150 and configured to restrict the flow direction of the coolant CL in the connecting pipe 150 . Specifically, the one-way valve 170 allows the cooling liquid CL to flow from the second condenser 140 to the first space S1, but prohibits the cooling liquid CL or the vapor CV evaporated from the cooling liquid CL from flowing from the first space S1 to the second condenser. 140.

Please refer to picture 2. Figure 2 is a partial enlarged view of area A of Figure 1 . In practical applications, as shown in FIG. 2 , the immersion cooling system 100 further includes a first sealing component 160 . The first sealing element 160 is sealed between the cover 130 and the box 110 to improve the sealing performance between the cover 130 and the box 110, thereby reducing steam CV from the second space formed by the cover 130 and the box 110. Chances of S2 leaking.

Please refer to Figures 3 to 4. Figure 3 is an enlarged three-dimensional view of the second condenser 140 of Figure 1 . Figure 4 is a partially exploded schematic diagram of the second condenser 140 of Figure 3 . In practical applications, for example, the second condenser 140 may be a water-cooled condenser. As shown in FIGS. 3 and 4 , the second condenser 140 further includes a main 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 main body 141. The main 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 steam in the second space S2 into CV. The cooling liquid CL is condensed, and the cooling liquid CL flows back to the first space S1 through the connecting pipe 150 . The fan 142 is connected to the main body 141 and is configured to inhale gas into the main body 141 through the first through hole H1, that is, to inhale the steam CV in the second space S2 into the main body 141 through the first through hole H1. The inlet port 143 communicates with the body 141 and is configured to allow moisture W to flow into the body 141 . The outlet port 144 communicates with the body 141 and is configured to allow moisture W to flow out of the body 141 . By the water W flowing through the main body 141, the main body 141 can condense the steam CV in the second space S2 into the cooling liquid CL.

Furthermore, the second condenser 140 further includes at least one extension tube 145 . The extension tube 145 is connected to the main body 141 and communicates with the first through hole H1. The extension tube 145 has a plurality of second through holes H2. The second through holes H2 are arranged along the extension direction of the extension tube 145. When the fan 142 is started, the steam CV in the second space S2 will be sucked into the extension pipe 145 through the second perforation H2, and then sucked into the main body 141 through the first perforation H1, and then condensed into cooling by the main body 141. Liquid CL. Through the extension tube 145 and the second through holes H2 distributed thereon, the steam CV in the second space S2 can be more easily sucked into the main body 141 . Depending on the actual situation, the number of the first through holes H1 and the extension tubes 145 may be plural, but the present invention is not limited thereto.

Furthermore, the fan 142 is at least partially exposed outside the main body 141 . When the steam CV in the second space S2 is sucked into the main body 141 by the fan 142, the inhaled gas or the steam CV that is not condensed by the main body 141 will be discharged out of the main body 141 through the fan 142.

In other embodiments, the second condenser 140 may also be a non-water-cooled condenser, such as an air-cooled condenser or a thermoelectric condenser. In these cases, the second condenser 140 does not include the inlet port 143 and export port 144.

Please refer to Figure 5. Figure 5 is a schematic cross-sectional view of the immersion cooling system 100 of Figure 1 , in which the cover 180 is in an open state. In this embodiment, as shown in FIG. 5 , the box 110 has an opening OP, and the opening OP communicates between the first space S1 and the second space S2. The immersion cooling system 100 further includes a cover 180 . The cover 180 is pivotally connected to the box 110 and corresponds to the opening OP, and is configured to rotate relative to the box 110 to open or close the opening OP. As shown in FIG. 1 , when the cover 180 closes the opening OP, the cover 180 is spaced between the first space S1 and the second space S2 , that is, the first space S1 and the second space S2 are not connected to each other. In addition, for example, as shown in FIG. 5 , when the immersion cooling system 100 is being repaired and the cover 180 is opened relative to the opening OP, the first space S1 and the second space S2 are connected to each other. As mentioned above, since the cover 130 is disposed outside the box 110 and forms the second space S2 together with the outer surface of the box 110, the steam CV leaving the first space S1 through the opening OP of the box 110 will be Collected in the second space S2, the loss of the cooling liquid CL can be effectively avoided, and the operating cost of the immersion cooling system 100 can be effectively controlled.

Please refer to Figure 6. Figure 6 is a partial enlarged view of range B of Figure 1 . In practical applications, as shown in FIG. 6 , the immersion cooling system 100 further includes a second sealing component 190 . The second sealing element 190 is sealed between the cover 180 and the box 110 . When the cover 180 closes the opening OP, the second sealing element 190 can improve the sealing performance between the cover 180 and the box 110, thereby reducing the chance of steam CV leaking from the first space S1.
