Description

Technical Field

[0001] This utility model belongs to the field of heat dissipation technology for electronic devices, specifically relating to an immersion IGBT evaporative cooling tank. Background Technology

[0002] Evaporative cooling, from a thermodynamic perspective, utilizes the latent heat of vaporization during fluid boiling to remove heat, employing the principle of phase change. This cooling method, utilizing the latent heat of vaporization during fluid boiling, is called "evaporative cooling." The cooling medium absorbs heat at the evaporation end, turning into a gas, and circulates to the condensation end, releasing heat, then condensing back into a liquid and flowing back to the evaporation end. During this process, the pressure throughout the system constantly changes, and the gas and liquid continuously circulate. Currently, immersion cooling typically involves installing electronic components inside a sealed tank and cooling them by immersing them in coolant. However, electronic components require busbars for signal input or output. Currently, most busbars on tanks are fixed inside the tank, making it inconvenient to install and remove electronic components due to the limited internal space. Utility Model Content

The mounting bracket 3 is mounted on the insulating cover 2 and is used to install electrical components.

[0026] The immersion IGBT evaporative cooling tank provided in this embodiment, compared with the prior art, features a sealed box 1 with a clearance opening on one side along its length. An insulating cover 2 is detachably installed on the side of the sealed box 1 with the clearance opening. A mounting bracket 3 is bolted to the insulating cover 2, and multiple conductive components, such as busbars 33 or conductive bars, are sealed and connected to it. When installing electrical components, the components can be mounted on the mounting bracket 3 and connected to the conductive components to transmit power or signals to external devices. After the electrical components are installed on the insulating cover 2, the insulating cover 2 is then installed on the sealed box 1. Assembly of the electrical components can be completed outside the sealed box 1, and finally, the components are placed inside the sealed box 1 through the insulating cover 2. The operation is simple and convenient, facilitating both initial assembly and subsequent maintenance.

[0027] Specifically, in this embodiment, the electrical component is an IGBT module. The sealed enclosure 1 is filled with coolant, which can cool the IGBT module during operation.

[0028] Specifically, in this embodiment, multiple conductive components are installed on the insulating cover plate 2. The multiple conductive components are disposed through the insulating cover plate 2, and the connection between the conductive components and the insulating cover plate 2 is sealed and fixed with potting compound.

[0029] In some embodiments, the sealed box 1 described above may be as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 An inner side plate 11 is provided on the sealing box 1, with a set of opposite sides at the clearance opening bent inwards. A connecting rod for installing the insulating cover plate 2 is fixedly installed on the inner side plate 11. The inner side plate 11 is bent at the upper and lower sides of the clearance opening on the sealing box 1. A connecting rod is fixedly installed on the outer surface of the inner side plate 11. The connecting rod is a screw rod. The insulating cover plate 2 is provided with a through hole corresponding to the connecting rod. The insulating cover plate 2 can be fixed to the inner side plate 11 by the cooperation of the bolt and the connecting rod, so that the operating surface is located on the outside of the sealing box 1, making it convenient for the operator to fix the insulating cover plate 2 to the sealing box 1.

[0030] In some embodiments, the sealed box 1 described above may be as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2An outer side plate 12 is provided on the sealing box 1, located at the clearance opening, with its opposite sides bent outwards. The outer side plate 12 has through holes for installing the insulating cover plate 2. Both sides of the clearance opening along the width direction of the sealing box 1 have outer side plates 12 bent outwards. Corresponding through holes are provided on both the outer side plate 12 and the insulating cover plate 2, allowing the insulating cover plate 2 to be fixed to the sealing box 1 using bolts and nuts, facilitating operation by personnel. The combination of the outer side plate 12 and the inner side plate 11 secures the circumference of the insulating cover plate 2 to the sealing box 1, improving the stability of the insulating cover plate 2 installation.

[0031] In some embodiments, the sealed box 1 described above may be as follows: Figure 2 The structure shown. See also Figure 2 A supporting angle steel 13 is connected between the outer side plate 12 and the outer side wall of the sealing box 1. The supporting angle steel 13 has clearance holes corresponding to the through holes. The supporting angle steel 13 includes two mutually perpendicular flanges. One flange abuts against the outer side plate 12, and the other flange abuts against the side wall of the sealing box 1. The flange abutting against the outer side plate 12 has clearance holes corresponding to the through holes on the outer side plate 12. The supporting angle steel 13 can be fixed to the outer side plate 12 by bolts and nuts.

[0032] Specifically, in this embodiment, by setting up the supporting angle steel 13, the stability of the position of the outer side plate 12 can be improved, thereby improving the stability of the connection between the insulating cover plate 2 and the outer side plate 12.

[0033] In some embodiments, the insulating cover 2 and the sealed box 1 can be connected by, for example, Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 An annular sealing ring 21 is installed at the clearance opening of the sealing box 1, and the annular sealing ring 21 is attached to the sides of the inner side plate 11 and the outer side plate 12. The inner side plate 11 at the clearance opening of the sealing box 1 is bent inward, and the outer side plate 12 at the clearance opening of the sealing box 1 is bent outward. The connection between the inner side plate 11 and the inner wall of the sealing box 1 is sealed by welding, so that the annular sealing ring 21 can effectively abut against the inner side plate 11 and the outer side plate 12. When the insulating cover plate 2 is installed on the sealing box 1, the insulating cover plate 2 can squeeze the annular sealing ring 21 onto the outer side plate 12 and the inner side plate 11, realizing a sealed connection between the insulating cover plate 2 and the sealing box 1, effectively sealing the clearance opening on the sealing box 1.

[0034] In some embodiments, the insulating cover 2 may be adopted as follows: Figure 1 , Figure 3 The structure shown. See also... Figure 1 , Figure 3The mounting frame 3 includes a support frame 31 for abutting against the bottom of the sealed box 1, and two mounting plates 32 mounted on the support frame 31. The two mounting plates 32 are arranged parallel to each other at a distance, and the electrical components are mounted on the opposite sides of the two mounting plates 32. When the insulating cover plate 2 is installed on the sealed box 1, the support frame 31 supports the bottom of the sealed box 1, thus supporting the mounting plates 32. The support frame 31 includes two parallel support plates arranged at a distance, and a connecting plate connects the two support plates. The electrical components are mounted on the opposite sides of the two mounting plates 32, so that the electrical components are in contact with coolant on both sides during heat dissipation. At the same time, when the coolant undergoes a phase change due to heat, it makes it easier for the gas to be discharged to the top of the sealed box 1. It also makes reasonable use of the internal space of the sealed box 1 and ensures effective heat dissipation.

[0035] Preferably, in this embodiment, the bottom of the sealing box 1 is provided with a liquid inlet pipe, the axis of which is arranged along the length of the support frame 31, and the liquid inlet pipe is located between two support plates.

[0036] In some embodiments, the mounting bracket 3 described above may be as follows: Figure 1 , Figure 3 The structure shown. See also... Figure 1 , Figure 3 Both the support frame 31 and the mounting plate 32 have a hollow structure. The mounting frame 3 is made of steel plate bent and welded together. The hollow structure of the mounting frame 3 allows the gas generated during the phase change of the coolant to be effectively discharged from around the electrical components, and increases the contact area between the electrical components and the liquid, ensuring effective heat dissipation for the electrical components.

[0037] In some embodiments, the mounting plate 32 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 The mounting plate 32 has a bent fixing plate 321 for fixing to the insulating cover plate 2 and the inner wall of the sealing box 1. The fixing plate 321 is bent at the side plate of the mounting plate 32 near the insulating cover plate 2, and is used to fix the mounting plate 32 to the insulating cover plate 2, realizing the connection between the mounting plate 32 and the insulating cover plate 2. A reinforcing plate is provided at the top of the mounting plate 32 to enhance the strength of the mounting plate 32. The side of the reinforcing plate is bent to fix the fixing plate 321 to the inner wall of the sealing box 1. The fixing plate 321 is fixed to the insulating cover plate 2 and the inner wall of the sealing box 1 by bolts. The structure is simple and easy to operate, which facilitates the connection and installation between the mounting frame 3 and the insulating cover plate 2.

[0038] Specifically, in this embodiment, the panel on the side opposite to the insulating cover plate 2 on the sealed box 1 is detachably installed on the sealed box 1 and is sealed to the sealed box 1. When installing the insulating cover plate 2, the panel can be removed from the sealed box 1 first, and then the insulating cover plate 2 and the fixing plate 321 on the mounting plate 32 can be fixed to the sealed box 1 before the panel is fixed to the sealed box 1.

[0039] In some embodiments, the sealed box 1 described above may be as follows: Figure 3 The structure shown. See also Figure 3 A liquid level sensor 4 is also installed on the sealed box 1, and a through hole is provided on the support frame 31 for installing the sensing end of the liquid level sensor 4. The liquid level sensor 4 is installed on the top of the sealed box 1, and the sensing end of the liquid level sensor 4 extends into the sealed box 1. The sensing end of the liquid level sensor 4 is inserted into the support frame 31, thereby improving the stability of the installation of the liquid level sensor 4.

[0040] Specifically, in this embodiment, a temperature sensor for detecting the internal temperature of the sealing box 1 and a pressure sensor for detecting the internal pressure of the sealing box 1 are also installed on the sealing box 1.

[0041] In some embodiments, the sealed box 1 described above may be as follows: Figure 1 , Figure 4 The structure shown. See also... Figure 1 , Figure 4 A sealing cover 5 is detachably installed on the side of the sealing box 1 away from the clearance opening. The sealing cover 5 has a through hole for installing the busbar 33, and a sealing ring 331 is fitted on the outside of the busbar 33. When the sealing cover 5 is installed on the sealing box 1, the sealing ring 331 is located between the sealing box 1 and the sealing cover 5. The sealing cover 5 can also be detachably installed on the side of the sealing box 1 away from the clearance opening. A through hole for avoiding the busbar 33 is provided on the side wall of the sealing box 1. The sealing cover 5 has a through hole for installing the busbar 33, and a sealing ring 331 is fitted on the outside of the busbar 33. The busbar 33 can be installed on the mounting bracket 3 first and connected to the electrical components, and then the mounting bracket 3 can be placed inside the sealing box 1. When the mounting bracket 3 is placed inside the sealing box 1, the busbar 33 passes through the through hole on the side wall of the sealing box 1. Then, the sealing ring 331 is fitted onto the busbar 33, and the sealing cover 5 is used to press and seal the sealing ring 331 between the through hole on the sealing cover 5 and the through hole on the sealing box 1. This achieves a sealed connection between the busbar 33 and the sealing box 1. The structure is simple, and the installation is convenient and easy.

[0042] Preferably, in this embodiment, an annular groove for accommodating the sealing ring 331 is provided on the sealing cover 5.
