Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] The following is combined Figures 1-3 The following describes some embodiments of the present invention in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] In a first aspect, the present invention provides a portable liquid-cooled testing system, comprising a housing 1, a first test pipeline 4, a second test pipeline 5, a sensor assembly, a power module, a data processing unit, and a display device 2; the first test pipeline 4, the second test pipeline 5, the sensor assembly, the power module, and the data processing unit are all disposed within the housing 1, and the display device 2 is disposed on the outer wall of the housing 1; the sensor assembly is used to detect the internal medium data of the first test pipeline 4 and the second test pipeline 5; the data processing unit is signal-connected to the sensor assembly and the display device 2 respectively, and is capable of displaying the data detected by the sensor assembly through the display device 2.

[0027] In this embodiment, the outer casing 1 is a rigid protective structure with a reserved pipeline installation area and component fixing area inside, and a display device 2 mounting position on the outer side wall; the first test pipeline 4 and the second test pipeline 5 are independent medium flow channels, arranged in the pipeline installation area inside the outer casing 1; the sensor assembly is a discrete detection element, which forms a physical connection with the test pipeline; the power module is an independent power supply unit, fixed in the component fixing area; the data processing unit is an integrated circuit module, which is connected to each component through wires; the display device 2 is embedded in the mounting position on the outer side wall of the outer casing 1.

[0028] Specifically, the outer casing 1 provides physical protection and mounting support for the internal components, preventing interference from the external environment. The first test pipeline 4 and the second test pipeline 5 respectively realize the directional transmission of the test medium, providing a medium path for parameter detection. The core function of the sensor assembly is to convert the physical parameters of the test medium into transmittable electrical signals. The power module provides power support for all electrical components of the system, ensuring continuous system operation. The data processing unit is responsible for receiving the electrical signals from the sensor assembly, performing signal conversion and calculation, and then transmitting the processing results to the display device 2. The function of the display device 2 is to convert the processed digital signals into visual information for easy reading by operators.

[0029] In use, first connect the first test pipe 4 and the second test pipe 5 to the chiller 9 and the device under test respectively to form a medium flow path; then turn on the power module to supply power to the system; after the system starts, the sensor components detect the physical parameters of the medium in the test pipe in real time and transmit the electrical signal to the data processing unit; after the data processing unit processes the signal, it sends the result to the display device 2; the operator reads the test data through the display device 2 to complete the basic liquid cooling parameter detection.

[0030] In an optional embodiment, quick-connect sealing connectors 3 are provided at both ends of the first test line 4 and the second test line 5.

[0031] In this embodiment, quick-connect sealing connectors 3 are installed at all four ports of the first test pipeline 4 and the second test pipeline 5. These connectors are an integral part of the pipeline end structure and typically consist of a male and a female connector. The male connector includes a core with a sealing ring and an external locking sleeve, while the female connector includes a matching socket and a locking mechanism. The connector body is permanently and securely fixed to the end of the test pipeline via threaded connection, welding, or crimping. The manufacturing materials must possess sufficient mechanical strength and chemical compatibility with the cooling medium; brass, stainless steel, or reinforced engineering plastics are commonly used. The four quick-connect sealing connectors 3 enable all external fluid interfaces of the system to be quickly connected and disconnected.

[0032] The quick-connect sealing connector 3 enables rapid, reliable, and leak-free fluid connection between the test system and external hoses or equipment interfaces. The quick-connect function is achieved through its unique mechanical locking design; the operator typically only needs to align the male connector with the female connector, insert it, and apply slight force for the locking mechanism to automatically engage and secure the connection. For disassembly, simply pressing or sliding the release ring releases the lock, allowing for easy removal. This significantly simplifies the wrench operation required for traditional threaded connections and reduces pre-test preparation time. The sealing function relies on a precision sealing element inside the connector. In the locked state, the sealing ring is axially compressed, causing radial deformation and tightly fitting against the mating surface, forming the first static sealing barrier.

[0033] In an optional implementation, the sensor assembly includes a pressure sensor 7, a temperature sensor 6, and a flow sensor 8.

[0034] In this embodiment, the sensor assembly consists of a pressure sensor 7, a temperature sensor 6, and a flow sensor 8. All three adopt a modular design, are structurally independent, and are adapted to the system through a unified installation interface.

[0035] The core structure of pressure sensor 7 includes a pressure-sensitive core, a signal processing circuit, and a housing. The pressure-sensitive core is a silicon piezoresistive chip, manufactured using micromachining technology. Four strain gauges are integrated on the core surface, forming a Wheatstone bridge. The signal processing circuit includes a signal amplification chip, a filtering module, and a temperature compensation circuit, all encapsulated in a metal housing with a sealed design, achieving an IP67 protection rating. Pressure sensor 7 connects to the test pipeline via a threaded interface with a sealing gasket. Temperature sensor 6 uses a platinum resistance structure, with a PT100 platinum resistance wire as its core component, encapsulated in a stainless steel protective tube. The tube's tip is pointed for easy insertion into the test pipeline. The platinum resistance wire connects to a signal conversion module via leads. The conversion module is integrated into a plastic housing at the sensor's rear, with a snap-fit ​​mounting structure. The flow sensor 8 adopts an impeller structure, mainly composed of an impeller, a Hall element, a signal amplification circuit, and a tube. The impeller is made of lightweight engineering plastic and has streamlined blades on its surface. It is installed inside the tube through a bearing. The Hall element is fixed on the outside of the tube and corresponds to the magnet on the impeller. The tube has flange interfaces at both ends, which are connected to the test pipeline by bolts. The interfaces are sealed with rubber gaskets.

[0036] Specifically, in this embodiment, pressure sensor 7, temperature sensor 6, and flow sensor 8 work together to comprehensively and synchronously collect key state parameters of the cooling medium. The core function of pressure sensor 7 is to accurately measure the static pressure of the medium at a specific point in the test pipeline. Temperature sensor 6 accurately senses the temperature of the medium at a specific location. It is typically placed at the inlet and outlet of the test loop to obtain the temperature change of the medium before and after passing through the heat exchange equipment; this temperature difference is the direct basis for calculating the heat dissipation of the equipment. Flow sensor 8 continuously measures the volume or mass of the medium flowing through the pipeline per unit time. Flow data is the foundation for assessing the adequacy of the coolant supply, calculating heat dissipation, and analyzing the system's flow regime. The synchronous real-time acquisition of these three types of data provides an indispensable set of raw data for a comprehensive evaluation of the liquid cooling system's performance from both fluid dynamics and thermodynamics perspectives.

[0037] In practical system design and application, the arrangement of sensors must follow metrological principles. Typically, at least two pressure-temperature measurement point pairs are set up in a test system: one pair located upstream of the device under test in a straight pipe section, called the inlet measurement point; and one pair located downstream in a straight pipe section, called the outlet measurement point. That is, one pair is located on the first test pipeline, and the other pair is located on the second test pipeline. The flow sensor 8 is usually installed on a pipe section in the loop where the flow rate is relatively stable and the flow field distribution is uniform, such as the inlet main pipe. During the test, once the cooling medium circulation stabilizes, each sensor begins to continuously output signals. The pressure sensor 7 outputs a 4-20mA current loop signal or a 0-10V voltage signal, corresponding to pressure from 0 to full scale. The temperature sensor 6 outputs a resistance value or a microvolt-level thermoelectric potential. The flow sensor 8 may output an analog signal or a pulse frequency signal. The data processing unit synchronously samples these signals through its multi-channel acquisition card and calculates them into engineering values ​​in megapascals, degrees Celsius, and liters per minute according to the unique conversion formula of each sensor. What the operator ultimately sees on display device 2 are these calibrated and processed physical quantity readings that can be directly used for engineering judgment.

[0038] In an optional implementation, the pressure sensor 7 is a venturi tube sensor or a capacitive sensor.

[0039] In this embodiment, the pressure sensor 7 is a capacitive pressure sensor, which uses the medium to impact the pressure-sensitive diaphragm. After the pressure-sensitive diaphragm deforms, it changes the capacitance or dielectric constant, thereby deriving the medium pressure.

[0040] Capacitive pressure sensors have high measurement sensitivity and accuracy.

[0041] In this embodiment, the pressure sensor 7 can also be a venturi tube sensor, which can simultaneously measure pressure and flow rate.

[0042] It is understood that, in the embodiments, the pressure sensor 7 can be a capacitive sensor or a venturi sensor, but it is not limited to the above two methods. It can also be other types of pressure sensors, such as piezoelectric sensors, as long as it can detect the pressure of the medium in the first test pipeline and the second test pipeline.

[0043] In an optional implementation, an information storage module is also included; the information storage module is signal-connected to the data processing unit and is used to store the detection data transmitted from the data processing unit.

[0044] In this embodiment, the core function of the information storage module is to persistently store various types of detection data transmitted by the data processing unit. Specifically, this includes: raw flow, temperature, and pressure data collected by sensor components; derived indicators such as heat dissipation and pressure drop calculated by the data processing unit; alarm records during the test process, including alarm type, occurrence time, and abnormal data; and test parameter configuration information, such as threshold settings, communication protocol selection, and sensor calibration coefficients. The module supports two storage modes: one is real-time synchronous storage, where the data processing unit generates a set of valid data, typically every 10ms-1s, which can be adjusted through system settings. This is achieved by transmitting the data to the storage module via the communication interface, ensuring no data is lost. The other is cyclic overwrite storage, where when the storage capacity reaches its limit, the oldest historical data is automatically overwritten, or a data full alarm is triggered to prompt the operator to export the data, preventing storage overflow. Furthermore, the module supports rapid data retrieval, allowing data to be exported via the data processing unit or external debugging equipment, providing raw data support for test report generation, fault tracing, and performance optimization.

[0045] In this embodiment, a data transmission interface such as a USB interface is also provided, which facilitates copying data from the information storage module for archiving.

[0046] In an optional implementation, a signal transmission module is also included; the signal transmission module is used to transmit data from the data processing unit to the handheld terminal.

[0047] In this embodiment, the signal transmission module adopts a modular design. Its core structure includes a communication chip, antenna, signal conditioning circuit, and interface circuit, all encapsulated in a small metal shielded box and fixed to the electrical component mounting area of ​​the system housing 1 with bolts. The communication chip is a high-performance wireless communication chip, integrating an RF transceiver module, a baseband processing module, and a protocol stack, supporting multiple data transmission rates. The chip's power pins, data pins, and control pins are connected to the interface circuit via PCB traces. The antenna is a built-in PCB antenna, integrated on the PCB of the signal transmission module. The antenna's radiation direction faces outwards from the housing 1 to avoid signal obstruction by the metal shielding box. To enhance signal transmission distance, an external telescopic antenna can be used, connected to the module via an SMA interface, and mounted in a pre-drilled hole in the housing 1. The signal conditioning circuit includes a power filtering module, a signal amplification module, and an anti-interference module. The power filtering module uses an LC filter circuit to remove interference noise from the power line; the signal amplification module uses an RF amplifier to enhance the RF signal power output by the communication chip; and the anti-interference module employs a shielded grounding design to reduce the impact of external electromagnetic interference on signal transmission. The interface circuit includes a UART interface, an SPI interface, and a power interface. The UART interface is used for data interaction with the data processing unit, the SPI interface is used for module configuration and debugging, and the power interface is connected to the system power module via wires to obtain operating power.

[0048] In this embodiment, the communication chip, as the core component of the module, functions to convert digital test data output by the data processing unit into radio frequency signals, which are then transmitted through the antenna. Simultaneously, it receives control commands from the handheld terminal and transmits them to the data processing unit, achieving bidirectional communication. The antenna converts the electrical signals output by the communication chip into electromagnetic wave signals for radiation, and simultaneously converts the electromagnetic wave signals transmitted by the handheld terminal into electrical signals for transmission to the communication chip. The antenna's performance directly affects the signal transmission distance and stability. The signal conditioning circuit optimizes signal quality. The power supply filtering module removes ripple and interference from the power supply module's output voltage, providing a stable power supply for the communication chip and preventing power supply noise from causing abnormal chip operation. The signal amplification module enhances the power of the radio frequency signal, increasing the signal transmission distance. The anti-interference module, through shielding and grounding design, reduces electromagnetic interference generated by other internal electrical components (such as the data processing unit and power supply module) while resisting interference from the external electromagnetic environment, ensuring the reliability of signal transmission. The interface circuit's function is to connect the signal transmission module with other components of the system. The UART interface provides a standard serial communication link, enabling stable data and command transmission between the data processing unit and the signal transmission module. The SPI interface is used for module initialization configuration and firmware upgrades, facilitating later maintenance and functional expansion. The power interface ensures the module receives a stable operating voltage, supporting continuous operation. Furthermore, the signal transmission module features low-power functionality; the communication chip can enter sleep mode when there is no data transmission, reducing overall system power consumption and extending the power module's battery life.

[0049] In this embodiment, the signal transmission module can transmit information to the handheld terminal, or it can transmit information from the information storage module to the cloud for cloud storage.

[0050] In an optional implementation, the information transmission module supports at least one of the following wireless communication protocols: Wi-Fi, Bluetooth, or mobile networks.

[0051] In this embodiment, the circuit board of the signal transmission module is at least soldered and configured with a core chip conforming to one or more of the aforementioned international communication standards, along with all necessary peripheral circuits. For example, if Wi-Fi and Bluetooth are supported, a single-chip solution integrating dual-mode functionality is typically used; if mobile networks are supported, a separate cellular communication module is required, which includes a baseband processor, RF transceiver, power amplifier, and SIM card interface. The antenna design must be compatible with the operating frequency bands of the supported protocols, and wideband antennas or diversity antenna technologies may be used to optimize performance. The module's firmware or driver must include full stack support for the supported protocols.

[0052] In an optional embodiment, a handle is provided on the upper part of the outer casing 1, and a buffer support foot is provided on the lower part of the outer casing 1.

[0053] In this embodiment, the addition of a handle makes the testing system more portable and mobile. Figure 1 As shown, the two grooves on its top are where the handles are installed.

[0054] In this embodiment, the installation of buffer support feet can increase the stability of the overall equipment during placement and reduce vibrations caused by excessive flow rate.

[0055] Specifically, in this embodiment, there are multiple buffer support feet, which are evenly distributed to ensure balance during support.

[0056] In an optional implementation, an alarm module is also included; the alarm module is signal-connected to the data processing unit and can trigger an alarm when the detected data exceeds a set threshold.

[0057] In this embodiment, the alarm module is implemented by both hardware and software. The hardware includes an alarm trigger signal input interface, an alarm logic processing unit, a drive circuit, and an alarm actuator. The alarm actuator can be a visual alarm device, such as a high-brightness LED indicator or a dedicated alarm information area on a display screen; it can be an auditory alarm device, such as a piezoelectric buzzer or an electromagnetic speaker; or it can be a tactile alarm device, such as a miniature vibration motor. These actuators are arranged in conspicuous or easily perceptible locations on the housing 1. The software is a monitoring program integrated into the firmware of the data processing unit. This program runs continuously and is responsible for determining alarm conditions and issuing trigger commands. The alarm module is tightly connected to the data processing unit through internal circuitry.

[0058] Secondly, the present invention provides a method for testing liquid cooling performance using a portable liquid cooling test system as described in any of the foregoing embodiments, comprising the following steps: S1: Connect the first test line 4 and the second test line 5 to the liquid supply device through the quick-connect sealing connector 3 at one end, and connect them to the liquid cooling device under test through the quick-connect sealing connector 3 at the other end to form a test circuit. S2: Turn on the power module and liquid supply system to allow the test medium to circulate in the loop; S3: Real-time acquisition of flow, temperature, and pressure data via sensor components; S4: The data processing unit receives data, calculates real-time heat dissipation and pressure drop, and sends the results to the display device 2 and / or handheld terminal; S5: Evaluate whether the heat dissipation performance of the liquid cooling equipment under test meets the design requirements based on the results.

[0059] In this embodiment, step S1, connecting the loop, functions to construct a correct physical test environment, laying the foundation for measurement. Step S2, starting the loop, functions to establish stable hydrodynamic conditions, enabling the system to reach a dynamic equilibrium suitable for steady-state measurement. Step S3, data acquisition, utilizes the system's sensing capabilities to acquire all the raw input information required for evaluation. Step S4, data processing and transmission, uses the system's computing and communication capabilities to transform the raw information into intuitive performance indicators and deliver them to the evaluator. Step S5, evaluation and judgment, uses quantitative indicators and engineering knowledge to draw a final conclusion on whether the equipment performance meets the standards.

[0060] The beneficial effects of this invention are: By connecting the first test line 4 and the second test line 5 to the liquid cooling circuit, and measuring parameters such as temperature and pressure of the first test line 4 and the second test line 5 through the sensor assembly, the liquid cooling equipment can be monitored in real time, thereby improving the safety of the liquid cooling equipment during use.
