Description

Technical Field

[0001] This utility model relates to the field of liquid-cooled optical module structure technology, and in particular to a fully immersion liquid-cooled optical module testing device. Background Technology

[0002] The 400G fully immersion liquid-cooled optical module combines high-speed optical communication technology with fully immersion liquid cooling technology. The optical module uses optoelectronic devices to convert electrical signals into optical signals for transmission, and the receiving end then converts the optical signals back into electrical signals. The fully immersion liquid cooling technology completely submerges the optical module in coolant, allowing the circulating coolant to remove the heat generated by the module, achieving efficient heat dissipation for high-speed data transmission: supporting a data transmission rate of 400Gbps to meet the demands of high-speed data transmission.

[0003] Optical modules include PCB boards. The optical components mounted on the PCB boards are susceptible to interference from coolant refraction, causing optical path abnormalities. A cover plate can be installed on the PCB board to cover the optical components. However, the cover plate still poses a risk of leakage, and coolant may still enter through the cover plate, affecting the normal operation of the optical components. To address this, we propose a fully immersion liquid-cooled optical module detection device that can detect cover plate leakage by setting up a corresponding monitoring structure. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fully immersion liquid-cooled optical module testing device to solve the current situation.

[0005] The above-mentioned utility model objective is achieved through the following technical solution:

[0006] A fully immersion liquid-cooled optical module testing device includes a photoelectric sensor and an optical module body. The photoelectric sensor is installed in the optical module body. The optical module body includes a housing and a PCB board is installed inside the housing. A protective cover is fixedly provided on the upper surface of the PCB board. The protective cover is used to shield the optical devices set on the upper surface of the PCB board.

[0007] The photoelectric sensor is installed inside the protective cover to detect whether there is leakage inside the protective cover.

[0008] In a preferred embodiment, this utility model can be further configured as follows:

[0009] The housing includes an upper housing and a lower housing that are fixedly connected to each other.

[0010] In a preferred embodiment, this utility model can be further configured as follows:

[0011] The lower housing also has an installation groove on its inner side for mounting the PCB board.

[0012] In a preferred embodiment, this utility model can be further configured as follows:

[0013] The protective cover is fixedly connected to the PCB board by sealant.

[0014] In a preferred embodiment, this utility model can be further configured as follows:

[0015] The upper end of the protective cover is integrally formed with a protrusion, which together with the inside of the protective cover forms a cavity. The photoelectric sensor is installed in the cavity of the protrusion. The photoelectric sensor includes a transmitter and a receiver arranged vertically and horizontally. The upper surface of the receiver arranged below is on the same plane as the lowest surface of the optical device.

[0016] In a preferred embodiment, this utility model can be further configured as follows:

[0017] The PCB board is also electrically connected to a connector for inserting optical cables.

[0018] In summary, this utility model has at least one of the following beneficial technical effects:

[0019] During use, this utility model incorporates a photoelectric sensor inside the protective cover. The photoelectric sensor includes a transmitter and a receiver. When no coolant seeps into the cover, the light emitted by the transmitter is normally received by the receiver. However, when coolant seeps into the cover, it is higher than the receiver at the bottom. Due to refraction, the receiver cannot receive the light from the transmitter. This allows the system to alert staff to the problem of coolant seepage through mechanisms such as alarms. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 3-5 The present invention provides the following technical solution: a fully immersion liquid-cooled optical module testing device, including a photoelectric sensor and an optical module body 30. The photoelectric sensor is installed in the optical module body 30. The optical module body 30 includes a housing, and a PCB board 303 is also installed inside the housing. A protective cover 305 is fixedly provided on the upper surface of the PCB board 303. The protective cover 305 is used to shield the optical devices set on the upper surface of the PCB board 303.

[0029] A photoelectric sensor is installed inside the protective cover 305 to detect whether there is any leakage inside the protective cover 305;

[0030] In a preferred embodiment, this invention can be further configured as follows: Figure 3 As shown, the housing includes an upper housing 306 and a lower housing 301 that are fixedly connected to each other. The lower housing 301 also has a mounting groove 302 on its inner side for mounting the PCB board 303.

[0031] The protective cover 305 is fixedly connected to the PCB board 303 through sealant, effectively protecting the optical components on the PCB board 303.

[0032] In a preferred embodiment, this invention can be further configured as follows: Figure 3-4 As shown, a protrusion 3051 is integrally formed on the upper end of the protective cover 305. The protrusion 3051 and the protective cover 305 together form a cavity 3052. The photoelectric sensor is installed in the cavity 3052 of the protrusion 3051. The photoelectric sensor includes a transmitter 3054 and a receiver 3053 arranged in parallel at the top and bottom.

[0033] In a preferred embodiment, this invention can be further configured as follows: Figure 5 As shown, the upper surface of the receiver 3053 positioned below is on the same plane as the lowest surface of the optical device;

[0034] When this liquid-cooled optical module is in use, at this time, as Figure 5As shown, the light emitted by the transmitter 3054 is normally received by the receiver 3053. However, if the protective cover 305 leaks liquid and the height of the coolant exceeds that of the receiver 3053, the light emitted by the transmitter 3054 will be refracted by the coolant and will not be correctly received by the receiver 3053. Since the upper surface of the receiver 3053 is on the same plane as the lowest surface of the optical device, this also means that the coolant has covered the lowest optical device. Therefore, the user can be alerted by the abnormality of the photoelectric sensor.

[0035] In a preferred embodiment, this invention can be further configured as follows: Figure 3 As shown, a connector 304 is also electrically connected to the PCB board 303 for inserting optical cables;

[0036] This utility model also provides a liquid-cooled optical module assembly, which applies the detection device. Specifically, it includes a cooling box 10, in which multiple optical module bodies 30 are disposed. The cooling box 10 contains a coolant, which can be a fluorinated liquid or other liquid with good cooling effect and has a non-conductive effect. The coolant immerses the optical module bodies 30 for cooling.

[0037] In a preferred embodiment, this invention can be further configured as follows: Figure 1 As shown, an inlet hole 11 and an outlet hole 12 are also provided on the side of the cooling tank 10. The cooling system also includes a circulation pump and a coolant tank (not shown in the diagram). The circulation pump draws coolant from the tank and replenishes it to the cooling tank 10. In addition, the inlet hole 11 and the outlet hole 12 are located on the same horizontal line.

[0038] In a preferred embodiment, this invention can be further configured as follows: Figure 2 As shown, the cooling box 10 is also equipped with an assembly 22 for assembling multiple optical module bodies 30. The assembly 22 has multiple mounting slots corresponding to the optical module bodies 30. The optical module bodies 30 can be inserted into the assembly 22 through the mounting slots. A cover plate 20 is also fixedly installed on the upper end of the assembly 22. Multiple sets of holes and slots 21 are evenly opened along the upper surface of the cover plate 20. The coolant in the cooling box 10 completely submerges the optical module bodies 30 through the holes and slots 21 to cool the optical module bodies 30.

[0039] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
