Description

[Technical field]

[0001] The present invention relates to a connection technology that enables communication within a sealed container. [Background technology]

[0002] In recent years, immersion cooling has been attracting attention as a method for cooling electronic devices such as computers. Immersion cooling is a technique for cooling an electronic device by immersing the device itself in a refrigerant tank. For example, Patent Document 1 discloses an immersion cooling device in which an electronic device is immersed in a refrigerant tank filled with refrigerant and the refrigerant in the tank is forced to flow, thereby increasing the cooling efficiency.

[0003] Since such a refrigerant tank is a sealed container, a hermetic connector is usually provided on the container wall to enable communication with the electronic device inside the container. The hermetic connector is sealed with resin and is used in many sealed containers (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] The communication connection device of the present disclosure has a structure in which a first member sandwiches a light-transmitting member provided on the wall of a sealed container from inside the container, and a second member sandwiches the light-transmitting member from outside the container. A self-aligning mechanism is provided on each connection surface of the first member and the second member facing the light-transmitting member, in which magnetic force generating parts that attract each other are formed in the same pattern. The self-aligning mechanism can determine the position of the second member relative to the first member in a self-aligning manner so that the optical axes of the optical input / output parts of each member are aligned. Since optical communication with the inside of the sealed container is possible through the light-transmitting member, there is no need to seal it with resin as in a hermetic connector, and the durability of the sealed container can be improved without compromising its airtightness.

[0011] The communication connection device and the sealed container of the present disclosure will be described in detail below with reference to the drawings. However, the components described in the following embodiments and examples are merely examples, and are not intended to limit the technical scope of the present invention.

[0012] 1. First aspect 1.1) Configuration As shown in FIG. 1, a sealed container 100 for immersion cooling comprises a container body 101 and a lid 102, and a coolant 103 is sealed in the container so that it can flow. An electronic device 201 such as a computer is fixed in the container by a support plate 202 and is immersed in the coolant 103. A wireless connection unit 300, which is an example of a communication connection device of the present disclosure, is provided on the lid 102. The wireless connection unit 300 is connected to the electronic device 201 through an optical cable 203, and enables transmission and reception of signals between the electronic device 201 and the outside. The configuration of the wireless connection unit 300 will be described in detail below with reference to FIG. 2 and FIG. 3.

[0013] 2, the wireless connection unit 300 is composed of a first member 310, a second member 320, and a light-transmitting member 330. The first member 310 is provided inside the container (hereinafter referred to as the internal connector 310). The second member 320 is provided outside the container (hereinafter referred to as the external connector 320). The light-transmitting member 330 is sandwiched between the internal connector 310 and the external connector 320, and is composed of a material (such as glass) that transmits at least the light for optical communication (hereinafter referred to as the light-transmitting plate 330).

[0014] The internal connector 310 has a cylindrical shape along the optical axis O, has a light guide 311 for optical communication embedded along the optical axis O, and has a connection surface 312 perpendicular to the optical axis O at its tip. The body of the internal connector 310 is made of a non-magnetic material, and may be, for example, a copper alloy with a gold-plated finish. An input / output surface 311a of the light guide 311 is exposed at the center of the connection surface 312. Furthermore, at least one magnet M1, which is a magnetic force generating unit, is arranged in a predetermined pattern around the input / output surface 311a of the light guide 311 on the connection surface 312. A screw portion 313 is formed on the side of the internal connector 310. Furthermore, the internal connector 310 has a coupling portion 314 at its rear end, and the optical fiber of the optical cable 203 extends to the connection surface 312 as the light guide 311 through the coupling portion 314.

[0015] The external connector 320 has a cylindrical shape along the optical axis O, a light guide 321 for optical communication is embedded along the optical axis O, and a connection surface 322 perpendicular to the optical axis O is provided at the tip. The body of the external connector 320 is made of a non-magnetic material, and may be, for example, a copper alloy with a gold-plated finish. The connection surface 322 of the external connector 320 has the same shape and size as the connection surface 312 of the internal connector 310. The input / output surface 321a of the light guide 321 is exposed at the center of the connection surface 322. Furthermore, at least one magnet M2, which is a magnetic force generating unit, is arranged around the input / output surface 321a of the light guide 321 on the connection surface 322. The at least one magnet M2 is arranged in the same pattern as the counterpart magnet M1 as described later, and has magnetic poles that exert an attractive force between the magnet M1 and the magnet M1. Such magnets M1 and M2 of the same pattern constitute a self-aligning mechanism, and self-aligning positioning of the external connector 320 with respect to the internal connector 310 is possible.

[0016] A guide protrusion 323 extending along the optical axis O is provided at a predetermined position on the side surface of the external connector 320. The rear end of the external connector 320 has a coupling portion 324, and the optical fiber of the optical cable 401 extends through the coupling portion 324 to a connection surface 322 as a light guide path 321. The optical cable 401 can be connected to an external processing device (not shown).

[0017] The light-transmitting plate 330 is embedded in the container wall (here, the wall of the lid 102) of the sealed container 100 so as to cover a through-hole provided in the container wall. This allows the light-transmitting plate 330 to maintain the sealed state of the container without relying on resin sealing such as a hermetic connector. The light-transmitting plate 330 has a first surface 331 facing the inside of the container and a second surface 332 facing the outside of the container.

[0018] The through hole in the container wall and the first surface 331 of the light-transmitting plate 330 form an inner recess 341 (hereinafter referred to as the inner receiving portion 341). A threaded portion 342 is formed on the side wall of the inner receiving portion 341. The internal connector 310 is inserted in the direction of arrow A, and the threaded portion 313 screws into the threaded portion 342 of the inner receiving portion 341. The internal connector 310 is fixed to the container wall by screwing into the inner receiving portion 341, and the light guide 311 is arranged along the optical axis O.

[0019] The through hole in the container wall and the second surface 332 of the light-transmitting plate 330 form an outer recess 351 (hereinafter referred to as the outer receiving portion 351). A guide groove 352 for positioning is formed at a predetermined position of the outer receiving portion 351. The outer receiving portion 351 is formed to have a diameter slightly larger than the external connector 320, and the guide groove 352 is also formed to be slightly larger than the guide protrusion 323. This makes it easy to fit the external connector 320 into the outer receiving portion 351 by aligning the guide protrusion 323 with the guide groove 352. When the connection surface 322 of the external connector 320 contacts the second surface 332 of the light-transmitting plate 330, the magnet M2 of the connection surface 322 is attracted to the magnet M1 of the internal connector 310, so that the external connector 320 is stabilized at a predetermined position in the outer receiving portion 351.

[0020] As described later, the magnets M1 and M2 are arranged in the same pattern centered on their respective light guides. Therefore, the light guide 321 of the external connector 320 is positioned on the same optical axis O as the light guide 311 of the internal connector 310. This allows optical signals to be transmitted and received between the inside and outside of the sealed container 100 through the light guide 311, the light-transmitting plate 320, and the light guide 321. The thickness of the light-transmitting plate 330 is designed to be thick enough to maintain the magnetic force of attraction between the inner magnet M1 and the outer magnet M2 while maintaining the airtightness of the sealed container 100.

[0021] 3, when the external connector 320 is stabilized at a predetermined position in the outer receiving portion 351, the external connector 320 is fixed in this stable state to the container wall by an openable / closable fixing means such as a hook-and-loop fastener 325. Note that the internal connector 310 and the external connector 320 are not limited to being cylindrical in shape, and may be polygonal in shape (such as a square prism).

[0022] In this way, optical communication with the inside of the sealed container 100 is possible through the light-transmitting plate 330, so there is no need to seal with resin as in a hermetic connector, and the durability of the sealed container 100 can be improved without compromising its airtightness.

[0023] 1.2) Self-alignment mechanism The self-alignment mechanism can be configured by magnets M1 and M2 of the same pattern. Below, examples of the arrangement patterns of magnets M1 and M2 will be described.

[0024] In the first example shown in Fig. 4, ring-shaped magnets M1 / M2 are provided on the connection surfaces 312 and 322 of the internal connector 310 and the external connector 320, respectively, with the light input / output surfaces 311a / 321a at their centers. The magnet M1 of the internal connector 310 and the magnet M2 of the external connector 320 have the same shape and have opposite polarities that attract each other. Therefore, the light guide path 321 of the external connector 320 can be positioned in a self-aligned manner on the same optical axis O as the light guide path 311 of the internal connector 310. Note that in the example of Fig. 4, the inclination of the external connector 320 with respect to the internal connector 310 is arbitrary, so the guide groove 352 and the guide protrusion 323 are not necessary.

[0025] In the second example shown in Fig. 5, magnets M1 and M2 are provided on the connection surfaces 312 and 322 of the internal connector 310 and the external connector 320, respectively, at positions equidistant from the light input / output surfaces 311a / 321a in opposite directions (positions symmetrical about a point). The magnets M1 and M2 of the internal connector 310 and the external connector 320 have opposite polarities that attract each other at the same position. Therefore, the light guide path 321 of the external connector 320 can be positioned in a self-aligning manner on the same optical axis O as the light guide path 311 of the internal connector 310. Note that in the example of Fig. 5, the inclination of the external connector 320 with respect to the internal connector 310 is either 0° or 180°, so the guide groove 352 and the guide protrusion 323 are not necessary.

[0026] In the second example, two magnets M1 and M2 are used, but the present disclosure is not limited to this. Three or more magnets may be arranged at equal distances and equal intervals (or point symmetrically) from each light input / output surface 311a / 321a. Below, an example in which 12 magnets are arranged is shown.

[0027] In the third example shown in FIG. 6, twelve magnets M11 to M12 are provided on the connection surface 312 of the internal connector 310. 12 are arranged in a pattern equidistant from the light input / output surface 311a. Similarly, twelve magnets M21 to M2 12 The magnets M11 to M1 on the mating connection surface 312 12 That is, for x (x=1, 2, . . . or 12), magnet M1 x and magnet M2 x The magnets M1 and M2 are opposed to each other via the light-transmitting plate 330. x and magnet M2 x and the internal connector 310 can be positioned on the same optical axis O in a self-aligning manner, similarly to the first and second examples.

[0028] 1.3) Key Function Furthermore, in a third example shown in FIG. 6, magnets M1 are arranged in a desired pattern. xand magnet M2 x By setting the magnets M1 and M2 to have opposite magnetic poles, it is possible to determine whether the connection between the external connector 320 and the internal connector 310 is correct or not. x and magnet M2 x By setting the magnets in different patterns, it is possible to determine whether the external connector 320 and the internal connector 310 are a correct combination. In other words, a key function can be realized by changing the magnet arrangement pattern. In this case, it is desirable to provide angle fixing means such as guide groove 352 and guide protrusion 323 to keep the inclination of external connector 320 relative to internal connector 310 constant. An example of the key function will be described below with reference to FIG. 7.

[0029] The arrangement positions of the magnets are predetermined in the internal connector 310 and the external connector 320. The internal connector 310 is provided with magnets M11 to M12 shown in FIG. 12 However, the external connector 320 is provided with magnets M21 to M22 shown in FIG. 12 are arranged on the external connector 320. The external connector 320 has a guide protrusion 323.

[0030] As illustrated in FIG. 7, the internal connector 310 includes magnets M11 to M1 12 are magnets with N, N, S, N, S, N, S, S, N, N, S, and S poles, respectively. This internal connector 310 is referred to as a keyhole KSi. Therefore, if an external connector 320 has magnets with opposite polarities arranged in the same position, the connection relationship is correct. That is, magnets M21 to M2 12 The external connectors 320, which are magnets with S, S, N, S, N, S, N, N, S, S, N and N poles respectively, provide the correct key Ki.

[0031] If the key Ki is correct, the external connector 320 is most strongly attracted to the outer recess 351, and it is clear that the connection is correct. Conversely, if the key Kj has a different magnet arrangement, the same magnetic poles face each other and repel each other, so the external connector 320 of the key Kj is not attracted to the outer recess 351, and it is clear that the connection is incorrect. In this way, it is possible to determine whether the connection of the external connector 320 is correct or not from the difference in attractive force, and incorrect connection can be prevented.

[0032] Theoretically, in the example of arranging n magnets, n With n=12, there are 4096 possible keys.

[0033] 2. Second Aspect In the wireless connection unit 300 according to the first aspect described above, the light input / output surfaces of the light guides 311 and 321 face each other via the light-transmitting plate 330, but the connection device of the present disclosure is not limited to this. Instead of the waveguide, an interface including a light-emitting unit that converts an electrical signal into an optical signal and a light-receiving unit that converts the optical signal into an electrical signal may be configured to face each other via the light-transmitting plate 330.

[0034] Hereinafter, the wireless connection unit 300A according to the second embodiment will be described with reference to Fig. 8. However, only configurations different from those of the first embodiment will be described, and members having the same functions will be given the same reference numerals and descriptions thereof will be omitted.

[0035] As illustrated in Fig. 8, in the wireless connection unit 300A, an optical transmitter / receiver 362 is provided in the internal connector 361, and its optical input / output surface is located at the center of the connection surface 312 as illustrated in Figs. 4 to 6. The optical transmitter / receiver 362 includes a laser light source that converts an electrical signal into an optical signal and a photodetector that converts the optical signal into an electrical signal, and the optical input / output surface thereof faces the light-transmitting plate 330. The input / output line of the optical transmitter / receiver 362 is connected to the electronic device 201 through a coupling portion 363 and an internal cable 364. The arrangement of the magnet M1 having a self-aligning mechanism or a key function is as illustrated in Figs. 4 to 6, and the other configurations are as described in the first embodiment.

[0036] Similarly, an optical transceiver 372 is provided in the external connector 371, and its optical input / output surface is located at the center of the connection surface 322 as illustrated in Figs. 4 to 6. The optical transceiver 372 includes a laser light source that converts an electrical signal into an optical signal and a photodetector that converts the optical signal into an electrical signal, and the optical input / output surfaces thereof face the light-transmitting plate 330. The input / output lines of the optical transceiver 372 are connected to an external processing device through a coupling portion 373 and an external cable 374. The arrangement of the magnet M2 having a self-aligning mechanism or a key function is as illustrated in Figs. 4 to 6, and the other configurations are as described in the first embodiment.

[0037] 3. Third Aspect Although one wireless connection unit 300 is provided in the sealed container 100 illustrated in Fig. 1, the sealed container of the present disclosure is not limited to this. Hereinafter, a sealed container provided with multiple wireless connection units will be described as a third embodiment. However, configurations different from the sealed container 100 illustrated in Fig. 1 will be described, and components having the same functions will be given the same reference numbers and descriptions thereof will be omitted.

[0038] 9, sealed container 100A for immersion cooling has lids 102A and 104 provided on both ends of cylindrical container body 101A. Wireless connection units 300(1) and 300(2) using optical communication according to the first embodiment described above are formed on lid 102A. Wireless connection unit 500 using electromagnetic induction or electric field coupling, which will be described later, is formed on lid 104. In the case of the electromagnetic induction method, it is desirable to install wireless connection unit 500 as far away as possible from wireless connection units 300(1) and 300(2) using magnets M1 / M2, that is, in a location where it is not affected by electromagnetic induction.

[0039] Each of the wireless connection units 300(1) and 300(2) has an internal connector and an external connector with the key function described in FIG. 6 and FIG. 7. Hereinafter, the internal connector 310 is referred to as a keyhole KS, and the external connector 320 is referred to as a key K. That is, in the wireless connection unit 300(1), the external connector K(1) is properly connected to the internal connector KS(1) and faces the internal connector KS(1) via a light-transmitting plate 330(1). In addition, in the wireless connection unit 300(2), the external connector K(2) is properly connected to the internal connector KS(2) and faces the internal connector KS(2) via a light-transmitting plate 330(2). Even when a plurality of wireless connection units 300 are provided in this way, by providing a different keyhole KS and key K for each wireless connection unit, it is possible to reliably prevent erroneous connection.

[0040] The internal connector KS(1) is connected to the electronic device 201 through the optical cable 203(1), and the internal connector KS(2) is connected to the electronic device 201 through the optical cable 203(2). The external connector K(1) is connected to an external processing device through the optical cable 401(1), and the external connector K(2) is connected to an external processing device through the optical cable 401(2). The configuration and function of each wireless connection unit are as described in the first aspect, and therefore description thereof will be omitted. The internal connector and the external connector may be the same as those in the second aspect described above.

[0041] The wireless connection unit 500 is connected to the electronic device 201 through a cable 204 and to an external power source through a cable 601, and supplies power to the electronic device 201 by electromagnetic induction. The configuration of the wireless connection unit 500 will be described below with reference to FIG.

[0042] 10, wireless connection unit 500 is composed of a first member 510, a second member 520, and a partition member 530. First member 510 is provided inside the container (hereinafter referred to as internal connector 510). Second member 520 is provided outside the container (hereinafter referred to as external connector 520). Partition member 530 is sandwiched between internal connector 510 and external connector 520, and is composed of a non-metallic material such as glass or resin that can maintain airtightness and enable electromagnetic induction.

[0043] Internal connector 510 has a cylindrical shape, and electromagnetic induction receiving coil 511 is embedded along a connection surface perpendicular to central axis C. Threaded portion 512 is formed on the side of internal connector 510, and is fixed by screwing into the inner recess of cover 104. Furthermore, internal connector 510 is connected to electronic device 201 through coupling portion 513 and cable 204 at the rear end.

[0044] The external connector 520 has a cylindrical shape, and an electromagnetic induction transmitting coil 521 is embedded along a connection surface perpendicular to the central axis C. The transmitting coil 521 faces the receiving coil 511 across a partition member 530, and supplies power to the receiving coil 511 by electromagnetic induction.

[0045] A guide protrusion 522 extending along central axis C is provided at a predetermined position on the side surface of external connector 520. External connector 520 can be fitted into outer recess 540 formed by the through hole of lid portion 104 and partition member 503. At that time, alignment can be easily achieved by sliding guide protrusion 522 of external connector 520 into guide groove 541 formed in outer recess 540. External connector 520 is connected to a power source (not shown) through coupling portion 523 and cable 601.

[0046] The partition member 530 is embedded in the container wall (here, the wall of the lid 104) of the sealed container 100A so as to close a through hole provided in the container wall. The partition member 530 has a first surface facing the inside of the container and a second surface facing the outside of the container. The first surface faces the receiving coil 511, and the second surface faces the transmitting coil 521.

[0047] 10, when the external connector 520 is fitted into the outer recess 540, the external connector 520 is fixed to the container wall by an openable and closable fixing means such as a hook-and-loop fastener 524. Note that the internal connector 510 and the external connector 520 are not limited to a cylindrical shape, and may be a polygonal prism shape (such as a rectangular prism).

[0048] 4. Application Examples A liquid immersion cooling system for a spacecraft in which the above-mentioned sealed container (100, 100A) is applied to a pressure container for liquid immersion cooling will be briefly described below.

[0049] Hereinafter, each of the pressure vessels G1 to G3 using the sealed vessels (100, 100A) will be referred to as a "pressure vessel G," and the structure of the pressure vessel G will be described with reference to FIG.

[0050] 11, pressure vessel G for immersion cooling comprises a sealed cylindrical vessel body 701, a lid 702 is fixed to the bottom surface of vessel body 701, and a coolant 703 is sealed inside the pressure vessel. The lid 702 is provided with a coolant inlet IL through which the coolant flows into the vessel and a coolant outlet OL through which the coolant flows out to the outside. A support 704 fixed to the lid 702 is provided inside pressure vessel G, and electronic device 705 is fixed to the support 704. Thus, the coolant flows in from the coolant inlet IL, flows over electronic device 705, transferring heat or air bubbles, and flows out from the coolant outlet OL to the outside.

[0051] Furthermore, wireless terminals 706 and 707 for connecting to the intra-satellite network NET are provided on the cover 702. The wireless terminals 706 and 707 can be configured by the wireless connection units (300, 300A or 500) according to the first to third aspects described above.

[0052] The electronic device 705 can communicate with electronic devices or mission equipment in other pressure vessels through the wireless terminals 706 and 707. Here, the first embodiment described above is adopted, and the intra-satellite network NET is an optical network made of optical fibers. However, this is not limited to this, and if the second embodiment described above is adopted, the intra-satellite network NET may be a local area network that communicates by electrical signals. Alternatively, one of the wireless terminals 706 and 707 may be an optical terminal for an optical network, and the other may be an electrical terminal for a local area network.

[0053] The coolant 703 is a liquid having electrical insulation and thermal conductivity, and preferably contains hydrogen atoms in order to moderate and shield neutron radiation. For example, liquids such as alternative fluorocarbons or polyester can be used as the coolant 703.

[0054] As shown in FIG. 12, a satellite 800, which is a spacecraft, is equipped with a radiator 801 for radiating heat into space, and various mission equipment 802a and 802b. The radiator 801 may include multiple radiators (801a, 801b). Furthermore, electronic devices such as main computers in the satellite 800 are immersed in a coolant in pressure vessels G1 to G3 for liquid immersion cooling. Each pressure vessel Gi has a coolant inlet IL i and refrigerant outlet OL i (where i is an arbitrary integer equal to or greater than 1, but here i=1, 2, or 3). Pressure vessels G1 to G3, radiator 801, and control valves VL1 and VL2 constitute a heat transport network through a plurality of flexible pipes 803 through which a refrigerant flows.

[0055] The heat transport network may be configured so that immersion cooling can be efficiently performed in each pressure vessel. The refrigerant that has been heat exchanged in the radiator 801 flows into each pressure vessel, and the refrigerant that flows out of each pressure vessel returns to the radiator 801. The network configuration shown in Fig. 12 is one example.

[0056] In Fig. 12, control valve VL1 distributes the refrigerant flowing out from refrigerant outlet RO1 of radiator 101a between pressure vessels G1 and G3. The refrigerant flowing from control valve VL1 to refrigerant inlet IL1 of pressure vessel G1 immerses and cools the electronic devices in pressure vessel G1, and then flows out from refrigerant outlet OL1 to control valve VL2. The refrigerant flowing from control valve VL1 to refrigerant inlet IL3 of pressure vessel G3 immerses and cools the electronic devices in pressure vessel G3, and then flows from refrigerant outlet OL3 to refrigerant inlet RI1 of radiator 801a.

[0057] The coolant flowing out from the coolant outlet RO2 of the radiator 801b flows into the coolant inlet IL2 of the pressure vessel G2, immersion-cools the electronic devices in the pressure vessel G2, and flows out from the coolant outlet OL2 to the control valve VL2. The control valve VL2 allows the coolant flowing in from the pressure vessels G1 and G2 to flow out to the coolant inlet RI2 of the radiator 801b.

[0058] A forced flow generator for circulating the coolant in the heat transport network is provided on a flexible pipe 803 connected to the coolant outlet of the radiator 801. In this example, as a forced flow generator, an axial flow pump P1 is provided on the flexible pipe 803 connecting the coolant outlet RO1 of the radiator 801a and the control valve VL1. Also, an axial flow pump P2 is provided on the flexible pipe 803 connecting the coolant outlet RO2 of the radiator 801b and the coolant inlet IL2 of the pressure vessel G2.

[0059] In this way, the wireless connection unit 300 or 300A according to the first to third aspects can be applied as an optical or electrical terminal in the pressure vessel G used in the immersion cooling system. Furthermore, the wireless connection unit 500 according to the third aspect can also be applied for supplying power to the pressure vessel G. The wireless connection unit 300 or 300A enables optical communication with the inside of the pressure vessel G, and the wireless connection unit 500 enables the supply of power to electronic equipment inside the pressure vessel G. This eliminates the need for sealing with resin as in the case of a hermetic connector, and makes it possible to improve the durability of the pressure vessel G without compromising airtightness.

[0060] Furthermore, since the key function exemplified in FIG. 6 and FIG. 7 can be realized between the internal connector and the external connector, the cable connection of the pressure vessel G can be performed reliably and erroneous connection can be effectively prevented.
