Description

Technical Field

[0001] The invention relates to the technical field of fuses, in particular to a fuse that can be used in an immersion liquid cooling system. Background Art

[0002] With the rapid development of electronic technology, high-power density electronic devices are increasingly used in data centers, electric vehicles and other fields. In order to effectively dissipate the heat of these high-power density devices, immersion liquid cooling technology has gradually become an important solution. In an immersion liquid cooling system, electronic equipment is directly immersed in coolant, which can efficiently take away heat to ensure the normal operation of the equipment. However, in such a system, short circuit and overload failures of electrical equipment may still occur. When a fault occurs, if the circuit is not cut off in time, it may cause equipment damage, fire or even more serious safety accidents. Therefore, electronic equipment immersed in coolant is generally equipped with fuses, which are used to ensure that the electronic equipment can cut off the circuit in time when a fault occurs.

[0003] In the prior art, a Chinese patent with a publication number of CN117352346B discloses an auxiliary thermal fuse and a method for making the same, wherein the auxiliary thermal fuse comprises a high-insulation shell, a hardware terminal electrode block, a ceramic cover, a hot melt assembly and a plastic shell cover, wherein the high-insulation shell is hollow inside and has an opening at the top; two of the high-insulation shells are provided, and a plurality of thermosensitive fusible alloys are provided between the two hardware terminal electrode blocks, the thermosensitive fusible alloys are inserted into the inner side of the high-insulation shell, and a flux is injected into the interior of the high-insulation shell, and the flux covers the thermosensitive fusible alloys; the ceramic cover is covered on top of the solidified flux; the hot melt assembly comprises a ceramic heating plate, an over-temperature fuse and a high-insulation wire, the ceramic heating plate is vertically and relatively flatly attached to the inner two side surfaces of the hardware terminal electrode block, an over-temperature fuse is provided between the two ceramic heating plates, and the over-temperature fuse is connected to the ceramic heating plate, and two high-insulation wires are provided, and the two high-insulation wires are respectively connected to the two ceramic heating plates. Although the auxiliary thermal fuse provided by this solution can react and blow quickly without causing the problem of fragment failure, this type of fuse has a poor sealing effect and cannot be used in electronic equipment immersed in coolant.

[0004] like Figure 1 The figure shows a common internal welding structure diagram of a fuse product that can be used in electronic equipment immersed in coolant. The solder seems to fill the bottom of the end cap and the gap between the tube body and the end cap, but in the manufacturing process, due to the influence of various process parameters, a certain proportion of products cannot be guaranteed. In direct liquid cooling equipment, during the repeated power-on heating and cooling process, the air in the tube expands due to heat and is discharged / cooled and sucked into the coolant, eventually causing functional failure.

[0005] In summary, there is an urgent need in the market for a fuse that can be immersed in coolant for a long time without affecting the normal function of the fuse. Summary of the invention

[0006] The purpose of the present invention is to provide a fuse that can be used in an immersion liquid cooling system, aiming to improve the problem that some existing fuses have poor sealing effects and some fuses become ineffective and unusable due to long-term immersion in coolant.

[0011] Furthermore, it also includes a potting glue, which is poured into the space formed by the cover plate and the upper part of the ceramic shell. The potting glue relies on its own fluidity to further seal the gap between the ceramic shell, the melt and the cover plate.

[0012] Furthermore, an arc extinguishing medium is injected into the sealed space formed by the cover plate and the bottom of the ceramic shell, and the arc extinguishing medium is used to prevent the arc generated when the fuse is melted from spreading.

[0013] Furthermore, a filling hole is provided in the middle of the cover plate, and the filling hole is used to inject arc extinguishing medium into the sealed space formed by the cover plate and the ceramic shell; a sealing plug is provided inside the filling hole to seal the filling hole.

[0015] Furthermore, an annular spaced platform is provided on the inner side of the ceramic shell near the top, and a potting space is formed between the melt and the spaced platform for potting glue to smoothly seal the gap between the melt and the ceramic shell.

[0016] Furthermore, the parts where the melt protrudes from the two ends of the ceramic shell are set as clamps, and the clamps are clamped on both sides of the ceramic shell. The clamps are set as connecting parts for connecting with electronic equipment.

[0017] Furthermore, the clamp head is extended outward to form an insert, and the insert can be installed on the busbar of the electronic device by plugging or welding; the insert is provided with a bolt hole for connecting the insert to the electronic device by bolts.

[0019] Furthermore, the melting time and melting current of the fuse are calculated as follows: Assuming the rated current of the fuse is The resistance of the fuse is , the ambient temperature is , the temperature of the coolant is , the melting point of the fuse is The specific heat capacity of the fuse is , quality is , then the fuse breaking time Calculated by the following formula: in, is the heat dissipation coefficient, which depends on the properties of the coolant and the heat dissipation structure of the shell;

[0020] The breaking current of the fuse is Calculated by the following formula: in, Indicates the fusing current, A coefficient indicating the type of fuse in a fuse link. Indicates rated current.

[0039] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0040] Example 1

[0041] like Figure 2 and Figure 3 As shown, a fuse that can be used in an immersion liquid cooling system includes a ceramic shell 1, a melt 2 and a cover plate 3. The ceramic shell 1 is used to install and seal the various components of the fuse; the bottom of the melt 2 is arranged inside the ceramic shell 1, and the melt 2 arranged inside the ceramic shell 1 is convenient for rapid melting when a failure occurs in the electronic equipment. The top of the melt 2 protrudes from the opening at the top of the ceramic shell 1; the melt 2 protrudes from a part of the ceramic shell 1 to facilitate connection with the electronic equipment. The cover plate 3 is arranged inside the ceramic shell 1, and the cover plate 3 is mainly used to seal the bottom of the melt 2 to prevent the arc from spreading when the melt 2 melts. Sealing is performed between the cover plate 3 and the ceramic shell 1, the cover plate 3 and the melt 2, and the melt 2 and the ceramic shell 1. The cover plate 3 and the bottom of the ceramic shell 1 form a sealed cavity, and the bottom of the melt 2 is placed inside the cavity. The cavity is convenient for providing a stable sealed space for the bottom of the melt 2. The melting time and melting current of the melt 2 are calculated as follows: Assume that the rated current of the fuse is , the resistance of the fuse is , the ambient temperature is , the temperature of the coolant is , the melting point of the fuse is The specific heat capacity of the fuse is , quality is , then the fuse breaking time Calculated by the following formula: in, is the heat dissipation coefficient, which depends on the properties of the coolant and the heat dissipation structure of the shell;

[0042] The breaking current of the fuse is Calculated by the following formula: in, Indicates the fusing current, A coefficient indicating the type of fuse in a fuse link. Indicates rated current.

[0043] The melt types include copper, silver, copper-plated silver, copper-plated silver-tin, copper-plated tin, aluminum, zinc, copper+tin block (molten adhesion), or silver+tin block (molten adhesion), etc.

[0044] like Figure 5 and Figure 6As shown, it also includes potting glue 6, which is poured into the space formed by the cover plate 3 and the upper part of the ceramic shell 1. The potting glue 6 further seals the gaps between the ceramic shell 1, the melt 2 and the cover plate 3 by its own fluidity. The two-layer sealing structure can ensure that the entire fuse has a good sealing effect and can be immersed in the coolant for a long time. The arc extinguishing medium 7 is injected into the sealed space formed by the cover plate 3 and the bottom of the ceramic shell 1. The arc extinguishing medium 7 is used to extinguish the arc diffusion generated when the melt 2 is melted, to avoid the arc diffusion causing a fire, and also to avoid the burning of electronic equipment; the arc extinguishing medium 7 can be selected according to the electrical characteristics of the fuse, and can be air, quartz sand or other designed arc extinguishing materials.

[0045] The amount of the potting glue on the melt is determined by the following process: using a preset three-dimensional scanning technology to identify the coordinates of the contact point between the potting glue and the melt; and according to the coordinates of the contact point, using the following formula to calculate the contact area between the potting glue and the melt:

[0048] According to the contact area, the contact stress between the potting compound and the melt is calculated using the following formula:

[0049] in, represents the contact stress, represents the contact area, Indicates the bonding strength of the potting compound;

[0050] The historical external force between the potting glue and the melt is collected; when the contact stress is less than the historical external force, the contact area is adjusted to obtain an adjusted area; and the potting glue dosage of the potting glue is determined using the adjusted area.

[0051] The three-dimensional scanning technology, such as CT scanning, can identify the internal structure of an object, and the contact point coordinates refer to the coordinates where the potting glue contacts the melt.

[0052] Optionally, the process of adjusting the contact area refers to the process of adjusting the contact area based on the formula To adjust the contact area so that No less than the external forces endured by history.

[0054] like Figure 4 , Figure 6 and Figure 7 As shown, the gaps between the cover plate 3 and the ceramic shell 1, the cover plate 3 and the melt 2, and the melt 2 and the ceramic shell 1 are sealed by the structural adhesive 5, and the structural adhesive 5 firmly bonds the cover plate 3 and the melt 2 to the ceramic shell 1; the fixation by the structural adhesive 5 can form a stable structure between the cover plate 3 and the melt 2 and the ceramic shell 1, and the structural adhesive 5 can also play a sealing role, so that a stable sealed cavity is formed at the bottom of the cover plate 3 and the ceramic shell 1.

[0055] like Figure 7 and 8 As shown, an annular spaced platform 11 is provided on the inner side of the ceramic shell 1 near the top, and a potting space is formed between the melt 2 and the spaced platform 11, for the potting glue 6 to smoothly seal the gap between the melt 2 and the ceramic shell 1; this structure can prevent the gap between the melt 2 and the ceramic shell 1 from being too small, thereby causing the potting glue 6 to be unable to smoothly enter the gap between the melt 2 and the ceramic shell 1 by relying on its own fluidity.

[0056] like Fig. 9 As shown, the parts where the melt 2 protrudes out of the two ends of the ceramic shell 1 are set as clamps 21, and the clamps 21 are clamped on both sides of the ceramic shell 1. This structure can ensure that the melt 2 protruding out of the ceramic shell 1 can be stably connected to the melt 2. The clamp 21 is set as a connecting part for connecting with electronic equipment.

[0057] Example 2

[0058] like Fig.10 As shown, the difference between this embodiment and embodiment 1 is that the clamp head 21 is extended outward to provide a plug 22, and the plug 22 can be installed on the busbar of the electronic equipment by plugging or welding, which facilitates the installation of the entire fuse.

[0059] Example 3

[0060] like Fig.11 As shown, the difference between this embodiment and the embodiments 1 and 2 is that a bolt hole 23 is provided on the plug-in sheet 22 for connecting the plug-in sheet 22 to the electronic device through bolts.

[0061] Example 4

[0062] like Figure 2 and Figure 3 As shown, a fuse that can be used in an immersion liquid cooling system includes a ceramic shell 1, a melt 2 and a cover plate 3. The ceramic shell 1 is used to install and seal the various components of the fuse; the bottom of the melt 2 is arranged inside the ceramic shell 1, and the melt 2 arranged inside the ceramic shell 1 is convenient for rapid melting when a failure occurs in the electronic equipment. The top of the melt 2 protrudes from the opening at the top of the ceramic shell 1. A part of the melt 2 protrudes from the ceramic shell 1 is convenient for connection with the electronic equipment. The cover plate 3 is arranged inside the ceramic shell 1, and the cover plate 3 is mainly used to seal the bottom of the melt 2 to prevent the arc from spreading when the melt 2 melts. Sealing is performed between the cover plate 3 and the ceramic shell 1, the cover plate 3 and the melt 2, and the melt 2 and the ceramic shell 1. The cover plate 3 and the bottom of the ceramic shell 1 form a sealed cavity, and the bottom of the melt 2 is placed inside the cavity. The cavity is convenient for providing a stable sealed space for the bottom of the melt 2. The melting time and melting current of the melt 2 are calculated as follows: Assume that the rated current of the fuse is , the resistance of the fuse is , the ambient temperature is , the temperature of the coolant is , the melting point of the fuse is The specific heat capacity of the fuse is , quality is , then the fuse breaking time Calculated by the following formula: in, is the heat dissipation coefficient, which depends on the properties of the coolant and the heat dissipation structure of the shell;

[0063] The breaking current of the fuse is Calculated by the following formula: in, Indicates the fusing current, A coefficient indicating the type of fuse in a fuse link. Indicates rated current.

[0064] like Figure 5 and Figure 6As shown, it also includes a potting glue 6, which is poured into the space formed by the cover plate 3 and the upper part of the ceramic shell 1. The potting glue 6 further seals the gaps between the ceramic shell 1, the melt 2 and the cover plate 3 by its own fluidity. The two-layer sealing structure can ensure that the entire fuse has a good sealing effect and can be immersed in the coolant for a long time. The arc extinguishing medium 7 is injected into the sealed space formed by the cover plate 3 and the bottom of the ceramic shell 1. The arc extinguishing medium 7 is used to prevent the arc generated when the melt 2 is melted from spreading, avoiding the arc spreading and causing fire, and also avoiding the burning of electronic equipment; the arc extinguishing medium 7 can be selected according to the electrical characteristics of the fuse, and can be air, quartz sand or other designed arc extinguishing materials.

[0065] like Figure 2 As shown, a filling hole 31 is provided in the middle of the cover plate 3, and the filling hole 31 is used to inject arc extinguishing medium 7 into the sealed space formed by the cover plate 3 and the ceramic housing 1. A sealing plug 4 is provided inside the filling hole 31 to seal the filling hole 31.

[0066] like Figure 4 , Figure 6 and Figure 7 As shown, the gaps between the cover plate 3 and the ceramic shell 1, the cover plate 3 and the melt 2, and the melt 2 and the ceramic shell 1 are sealed by the structural adhesive 5, and the structural adhesive 5 firmly bonds the cover plate 3 and the melt 2 to the ceramic shell 1; the fixation by the structural adhesive 5 can form a stable structure between the cover plate 3 and the melt 2 and the ceramic shell 1, and the structural adhesive 5 can also play a sealing role, so that a stable sealed cavity is formed at the bottom of the cover plate 3 and the ceramic shell 1.

[0067] like Figure 7 and 8 As shown, an annular spaced platform 11 is provided on the inner side of the ceramic shell 1 near the top, and a potting space is formed between the melt 2 and the spaced platform 11, for the potting glue 6 to smoothly seal the gap between the melt 2 and the ceramic shell 1; this structure can prevent the gap between the melt 2 and the ceramic shell 1 from being too small, thereby causing the potting glue 6 to be unable to smoothly enter the gap between the melt 2 and the ceramic shell 1 by relying on its own fluidity.

[0068] like Fig.12 As shown, the portion of the melt 2 protruding from the top of the ceramic shell 1 is arranged perpendicular to the ceramic shell 1, and the portion of the melt 2 protruding from the top of the ceramic shell 1 is arranged as a vertical plug-in 24, and a through hole is provided on the vertical plug-in 24 for smoothly welding the vertical plug-in 24 to the electronic device.

[0069] Working principle: When in use, the corresponding shape of the connection part can be selected according to the use environment and the model of the electronic device, and the fuse with different arc extinguishing media 7 and different materials of the melt 2 can be selected according to the use requirements. After selecting the corresponding fuse, the two ends of the melt 2 protruding from the ceramic shell 1 are connected to the corresponding positions on the electronic device; then the entire electronic device can be immersed in the liquid cooling system. Since the fuse is double-sealed by the structural glue 5 and the potting glue 6, the coolant will not invade the inside of the fuse, so the fuse can be used normally in the coolant. When an electronic device fails, the circuit current of the electronic device is overloaded or short-circuited. At this time, the fuse 2 of the fuse will melt due to the current overload, and since the position where the fuse 2 is melted is placed in the arc extinguishing medium 7, the arc can be avoided. The position where the fuse 2 is melted is in a sealed space, even if there is a problem of excessive current, it will not cause a fire. Therefore, this structure can effectively protect electronic equipment.

[0070] To summarize, in the present application, a portion of the melt 2 is arranged inside the ceramic shell 1, and a portion of the melt 2 arranged inside the ceramic shell 1 is sealed inside the ceramic shell 1 by a sealing cover, so that the melt 2 inside the ceramic shell 1 can be effectively blocked, while the melt 2 arranged outside the ceramic shell 1 is connected to the electronic equipment; this can effectively prevent the melt 2 from contacting the coolant, and at the same time, the arc generated when the melt 2 melts will also be quickly annihilated because it cannot come into contact with the air, so as to avoid the arc causing a fire.

[0071] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
