Description

Technical Field

[0001] This invention belongs to the technical field of aircraft ground maintenance equipment, specifically relating to a small laboratory liquid-cooled terminal device and system. Background Technology

[0002] Before aircraft delivery, some experiments need to be conducted in the aircraft's onboard laboratory. Therefore, an onboard laboratory is usually built on the aircraft. The usable area of ​​the onboard laboratory is relatively small, and it has technical requirements such as electrostatic isolation and electromagnetic interference isolation. Therefore, when laying the floor, a structural framework needs to be built first, and then the anti-static floor is laid. Some parts being tested have high temperatures and need to be cooled by external liquid cooling equipment. The liquid cooling equipment is large, so it can only be set up outside the laboratory and connected to the parts being tested through hoses. However, since the distance between the liquid cooling equipment and the parts being tested is relatively far, it is inconvenient to control the liquid cooling equipment. Therefore, a liquid cooling terminal is built between the liquid cooling equipment and the parts being tested. The liquid cooling terminal controls the delivery and return of the coolant. The liquid cooling terminal is equivalent to the control unit and is an important intermediate link. The liquid cooling terminal cannot be too far away from the experimental equipment. Therefore, the liquid cooling terminal must be built in the onboard laboratory.

[0003] Traditional liquid-cooled terminals are bulky and difficult to install in confined spaces like onboard laboratories. Furthermore, their relatively fixed structure necessitates the integration of multiple sensors into external liquid-cooling devices. These devices have complex internal structures, making maintenance inconvenient and hindering the identification of fault sources. Therefore, integrating multiple sensors into a separate liquid-cooled terminal allows for immediate identification of fault sources, facilitating equipment repair and maintenance. This approach also reduces the development costs and size of liquid-cooling devices. Summary of the Invention

The mounting plate is a plate-like structure made of anti-static material to replace the anti-static floor in the laboratory. The overall liquid cooling terminal has a sunken structure, and its size is the same as that of the laboratory floor on the aircraft. It can be installed in the aircraft laboratory and connected to the parts to be cooled through a hose underground. It does not occupy the laboratory floor area and can be modularly replaced and maintained. It is easy to operate.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0023] Example 1: A small liquid-cooled terminal device for laboratory use, such as Figure 1 , Figure 2 and Figure 3 As shown, the device includes a mounting plate 1, a liquid supply assembly, a liquid return assembly, and a control assembly. The mounting plate 1 is a flat plate structure with a set of handles on its top surface for easy handling of the terminal device. The liquid supply assembly, liquid return assembly, and control assembly are all located at the bottom of the mounting plate 1. Multiple fixing components 13 are provided at the bottom of the mounting plate 1 to support and fix the liquid supply assembly and the liquid return assembly, ensuring their stability at the bottom of the mounting plate 1. The liquid supply assembly and the liquid return assembly are respectively connected to an external liquid cooling device and the part to be cooled. The liquid supply assembly and the liquid return assembly are located between the liquid cooling device and the part to be cooled. The coolant in the liquid cooling device enters the part to be cooled through the liquid supply assembly and hoses, and after cooling the part, it returns to the liquid cooling device through the liquid return assembly and hoses. The control assembly is used to control the on / off state and flow rate of the liquid supply assembly and the liquid return assembly.

[0024] Mounting plate 1 is made of anti-static material. The liquid-cooled terminal unit is installed in the onboard laboratory, but can also be used in other similar laboratories. The bottom of the onboard laboratory requires a structural frame and anti-static flooring. Mounting plate 1 is the same size and thickness as the anti-static flooring and is also made of anti-static materials, such as carbon fiber or polystyrene, pressed together. The liquid supply and return components are located below mounting plate 1. The entire liquid-cooled terminal is a recessed structure, connected to the parts to be cooled via flexible hoses underground, without occupying floor space and significantly improving space utilization. During installation, the pre-laid hoses under the floor are pulled out through the pre-drilled holes and connected to the liquid supply and return components. Then, mounting plate 1 is snapped onto the structural frame, flush with the rest of the floor. For disassembly and maintenance, the liquid-cooled terminal unit can be pulled out entirely using the top handle, and the connected hoses can be disconnected. Modular installation, removal, or replacement is possible, improving space utilization and simplifying maintenance, saving time.

[0025] The mounting plate 1 is equipped with multiple support members 14, each with a disc-shaped support foot at its bottom. The height of the support member 14 is higher than that of the liquid supply assembly, liquid return assembly, and control assembly. The support feet abut against the ground or external operating table to keep the liquid cooling terminal device stable and prevent the liquid supply assembly and liquid return assembly from being damaged by collisions with the ground or operating table. The liquid supply assembly includes an inlet solenoid valve 2, a filter 5, a pressure sensor 6, a flow sensor 7, and a liquid supply connector 8. The inlet solenoid valve 2, filter 5, pressure sensor 6, flow sensor 7, and liquid supply connector 8 are connected through a liquid supply pipeline 4. The filter 5 is located at the inlet... An air intake solenoid valve 3 is installed between the liquid solenoid valve 2 and the pressure sensor 6, and between the filter 5 and the liquid intake solenoid valve 2. The air intake solenoid valve 3 is used to drain the coolant from the liquid supply assembly and the liquid return assembly. After opening the air intake solenoid valve 3, the liquid intake solenoid valve 2 needs to be closed, and external gas enters the liquid supply line 4, the parts to be cooled, and the liquid return line 10. At this time, the electric needle valve 9 is opened to allow the coolant to flow into the liquid cooling equipment, thus draining the coolant from the liquid cooling terminal and the parts to be cooled. The coolant enters the liquid supply line 4 through the liquid intake solenoid valve 2, is filtered by the filter 5, and is then detected by the downstream pressure filter 5 and flow filter 5. The flow filter 5 sends the detection data to the control component. After judging the current data of the coolant, the control component can continuously supply coolant to the supply pipe 4, allowing the coolant to enter the parts to be cooled for cooling. The return component includes an electric needle valve 9, a temperature sensor, and a return connector 12. The end of the electric needle valve 9 is connected to a liquid cooling device. The electric needle valve 9, the temperature sensor, and the return connector 12 are connected through the return pipe 10. The return connector 12 is connected to the parts to be cooled. The temperature sensor is located between the electric needle valve 9 and the return connector 12. After the coolant cools the parts to be cooled, it flows into the return pipe 10 through the return connector 12. After the temperature sensor detects the temperature, it reaches the electric needle valve 9. The temperature sensor transmits the temperature of the coolant back to the control component. After the control component determines that the temperature is within the range that the liquid cooling equipment can withstand, it opens the electric needle valve 9, allowing the high-temperature coolant to enter the liquid cooling equipment. The supply connector 8 and the return connector 12 are both aviation liquid cooling self-sealing connectors, which can effectively prevent leakage and coolant backflow. The fixing component 13 includes a fixing rod and a clamp. One end of the fixing rod is connected to the mounting plate 1, and the other end is connected to the clamp. The clamp is connected to the fixed supply pipe 4 and the return pipe 10, fixing the supply pipe 4 and the return pipe 10 on the mounting plate 1.

[0026] Example 2: Multiple circulation solenoid valves are installed between the supply line 4 and the return line 10. The self-circulating solenoid valve 11 is connected to both the supply line 4 and the return line 10 via a hose. When cleaning the supply line 4 or the return line 10 is required, the supply connector 8 and the return connector 12 are short-circuited, the inlet solenoid valve 2 is opened, and the air inlet solenoid valve 3 is closed. The coolant flows through the supply line 4 and then through the hose into the return line 10 for internal circulation, thus cleaning the lines. The control components include an electrical control box 15, which is electrically connected to the inlet solenoid valve 2, pressure sensor 6, flow sensor 7, air inlet solenoid valve 3, electric needle valve 9, temperature sensor, and self-circulating solenoid valve 11. By collecting data from each sensor and controlling each valve, intelligent and automated circulation of coolant is achieved to cool external equipment, while simultaneously protecting the liquid cooling equipment and extending its service life. Other parts of this embodiment are the same as those in the above embodiment and will not be repeated here.

[0027] Example 3: A small-scale laboratory liquid cooling terminal system includes an installation module, a liquid supply module, a liquid return module, and a control module. The liquid supply module, liquid return module, and control module are all mounted on the installation module, which provides an installation platform for these modules. The control module is connected to both the liquid supply module and the liquid return module, and controls the liquid flow and coolant flow rate in both modules. The liquid supply module and the liquid return module are connected to external liquid cooling equipment and the parts to be cooled. The installation module includes a fixing unit and a support unit. The fixing unit secures the liquid supply module and the liquid return module to the installation module, replacing the floor of the installation area. The support unit provides structural support to the fixing unit, preventing collapse during foot traffic. This allows for sunken installation of the liquid supply module, liquid return module, and control module below ground level, improving space utilization. The support unit is used to support the installation module, so that the liquid supply module and the liquid return module are located between the bottom of the support unit and the installation module, which can prevent the liquid supply module and the liquid return module from being collided.

[0028] The coolant supply module includes a liquid inlet unit, a filtration unit, a pressure detection unit, a flow detection unit, and a liquid supply connection unit. The filtration unit, pressure detection unit, and flow detection unit are all located between the liquid inlet unit and the liquid supply connection unit. An air intake unit is located between the liquid inlet unit and the filtration unit. The coolant enters the liquid supply module through the liquid inlet unit, is filtered by the filtration unit, and after data detection by the pressure detection unit and the flow detection unit, the data is fed back to the control module. The control module controls the continuous supply or interruption of the coolant supply.

[0029] When coolant needs to be drained, the inlet unit can be closed, the air intake unit opened, and the drain unit opened to drain the coolant from the terminal system. The return module includes a drain unit, a temperature detection unit, and a return connection unit. The return connection unit is connected to the parts to be cooled. The temperature detection units are located between the drain unit and the return connection unit. Coolant flows from the external parts to be cooled through the return connection unit to the drain unit. The temperature detection unit detects the temperature of the returning coolant and sends the data to the control module. After determining the temperature of the coolant, the control module can open the drain unit to allow the coolant to flow back into the liquid cooling device. An internal circulation unit is set between the supply module and the return module. The internal circulation unit is used for internal circulation of coolant and can also perform self-cleaning of the supply module and the return module. The control module is connected to the inlet unit, air intake unit, pressure detection unit, flow detection unit, temperature detection unit, drain unit, and self-circulation unit. The control module controls the start and stop of the internal circulation unit of the inlet unit and the drain unit based on the data fed back by each detection unit and external control commands, forming an intelligent coolant supply and circulation system.

[0030] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this invention is usually placed in during use. They are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] Furthermore, the use of terms such as "horizontal" and "vertical" in the description of this invention does not imply that the components are required to be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0032] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way.
