Description

Technical Field

[0001] The present invention relates to the technical field of detection methods, and in particular to a liquid cooling line leakage detection device and a liquid cooling line detection method. Background Art

[0002] In today's liquid cooling industry, cooling methods play a vital role in ensuring the normal operation and performance of equipment. At present, the liquid cooling industry mainly uses two cooling methods: cold pipe cooling and immersion cooling. Among them, the cold pipe cooling method has certain characteristics and faces some technical challenges in practical applications.

[0003] In the cold pipe cooling system, leak detection is a key link. At present, cold pipe leak detection mainly relies on fine nylon induction wire. This detection method can detect coolant leakage to a certain extent, but it exposes obvious shortcomings in mass production.

[0004] For batch cable testing, the existing methods lack efficient solutions. Although the thin nylon induction wire can play a role in the detection of a single or a small number of cables, its detection efficiency is low when a large number of cables need to be tested at the same time, and it cannot meet the rapid detection requirements of large-scale production. This not only increases the time cost of detection, but may also affect the progress of the entire production process and reduce production efficiency.

[0005] Secondly, existing fixture testing has limitations. Although fixture testing can test cables to a certain extent, it cannot record data. This means that it is impossible to conduct effective data coordination and analysis for the test profile of the entire batch of cables. The lack of data records makes it difficult to conduct a comprehensive assessment of the quality of a batch of cables, and it is impossible to accurately track the performance stability and potential problems of the product, which is not conducive to subsequent quality improvement and production optimization.

[0006] In summary, in the cold tube cooling method of the liquid cooling industry, the current leakage detection method faces the problems of low detection efficiency and missing data records in batch conditions. It is urgent to develop a more efficient cable detection technology that can realize data recording and coordination to meet the needs of industry development. Summary of the invention

[0031] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, device, product or end including a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units inherent to these processes, methods, products or ends.

[0033] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] Example 1

[0035] A first aspect of the present invention discloses a liquid cooling line leakage detection device 100, comprising a code scanning unit 101 for obtaining a liquid cooling line code, wherein the code scanning unit is configured to read a QR code, a bar code, or a digital number;

[0036] A detection unit 102, which is connected to the code scanning unit, and is used to obtain the voltage value of the liquid cooling line;

[0037] A control unit 103 is connected to the detection unit, and is used to determine the state of the liquid cooling line according to the voltage value.

[0038] Those skilled in the art can understand that the detection unit, i.e., the liquid cooling line detection jig, generally includes a detection circuit part and a sensing line part connected to each other. When the liquid cooling line leaks, the cold liquid inside it seeps out and changes the voltage on the sensing line. In this embodiment, by modifying the existing detection jig and adding a scanning unit and a control unit, the beneficial effects of batch detection of liquid cooling lines and automatic sorting of detection data are achieved. In this embodiment, the scanning unit is preferably configured as a scanning gun for scanning barcodes.

[0039] Furthermore, this embodiment is modified on the basis of the original old fixture, adding an SD card and a USB serial port module, using the SD card for storage, and utilizing the large-capacity storage class interface in the USB communication technology to generate an operable U disk, and integrating an Excel library to automatically create an Excel file list and record each test data parameter. After the test is completed, it is connected to the computer via USB; a memory card slot for inserting an SD card is provided in the control unit, and the memory card slot is communicatively connected to the code scanning unit through a conversion interface; a data reading interface is also provided on the control unit, and the data reading interface is communicatively connected to the memory card slot, and the data reading interface is configured as a USB interface or an RS serial port.

[0040] The test steps of this liquid cooling line leakage detection device are as follows:

[0041] Step 1: Use a barcode scanner to scan the barcode to obtain the serial number.

[0042] Step 2: Long press the MENU button to enter the menu interface. Short press in the menu interface can switch menus. The menus include: mode setting interface; measurement time setting interface; mode 7 time setting. Use the up and down keys to modify. After modification, long press the ENTER button for 1S to save and exit. Long press the MENU button for 1S to exit without saving.

[0043] Step 3: Short press the NETER button, the buzzer beeps, and the liquid cooling line is tested. At the same time, the Normal word in the lower left corner of the interface will flash. When the measurement is completed, if there is no error, the word PASS will pop up; if there is an error, the word Err0X will pop up, and then proceed to step 3. 0X is the error code, as shown in the code table:

[0044]

[0045] Step 4: When the interface displays Err0X, if you do not want to record the result in the SD card table, short press the MENU key to discard the result, the display will return to the F 0X interface, and Normal will light up. Repeat the above steps to measure again; short press the ENTER key to save the result and return to the F 0X interface, and Leak will light up; similarly, when the interface displays PASS, short press the MENU key to discard the result, the display will return to the F 0X interface, and Normal will light up. If you short press the ENTER key, leak will light up after saving, and proceed to step 4.

[0046] Step 5: Soak the liquid cooling line with water to make it leak, then short press ENTER. When you hear a dripping sound, the test starts and the word Leak below will flash. If the liquid cooling line can detect water leakage normally, the controller will show a water leakage alarm state Err 01. If it is other cases, you can short press the MENU key to return and then re-measure. If it is confirmed that there is no water leakage alarm or it is a normal alarm, short press ENTER to save. After saving, Normal below lights up and returns to the original state.

[0047] Example 2

[0048] In order to efficiently detect and collect data of the entire batch of liquid cooling lines through the above-mentioned liquid cooling line leakage detection device, as Figure 2 As shown, this embodiment discloses a liquid cooling line detection method applied to the liquid cooling line leakage detection device as described above, comprising the following steps:

[0049] S1 assigns a sorting number to the code of the liquid cooling line based on the scanning order of the code scanned by the code scanning unit; specifically, first select different recording forms through different buttons, then use the code scanning gun to collect the serial number of the liquid cooling line to be tested, record it in the Excel library, and then start the test. After the test is completed, the data will be automatically recorded under the serial number in the Excel library, and the detection of different liquid cooling lines will be completed one by one to achieve fully automated data recording.

[0050] S2 establishes a record table and stores it in the control unit, wherein the record table includes a serial number, fault detection data and detection results;

[0051] It is understood that the record table is as follows:

[0052]

[0053] S3: the control unit responds to the start signal and obtains the voltage value returned by the detection unit, and obtains fault detection data and detection results according to the voltage value analysis;

[0054] S4 fills the fault detection data and the detection results into the corresponding sorting sequence number in the record table, repeats the above operation until all liquid cooling lines are detected, and exports the record table through the data reading interface.

[0055] A further technical solution of this embodiment is that before establishing a record table and storing it in the control unit, a mapping relationship between the record table and the buttons on the control unit is established, and the corresponding record table is called according to different button trigger signals received by the control unit during detection.

[0056] like Figure 3 As shown, in obtaining fault detection data and detection results according to the voltage value analysis, the following steps are also included:

[0057] S31, in response to the start signal, the controller sends switch action signals corresponding to different fault modes to the detection unit in sequence, so that the switch in the detection circuit is in different working positions;

[0058] S32 obtains the voltage value under each fault mode respectively, analyzes them in turn and obtains the corresponding fault detection data and detection results.

[0059] It is understandable that the failure modes include water leakage, open circuit, short circuit, crossover, and damage. Different voltage values ​​can be directly judged as corresponding failure types based on experience, as shown in the following table:

[0060]

[0061] A further technical solution of this embodiment is that during the detection process, the fault detection data and detection results obtained by the control unit are stored in a cache register, and after the detection is completed, it is determined in response to a storage signal or a deletion signal whether the fault detection data and detection results are stored in the storage card.

[0062] The beneficial effect of the present application is that by arranging a code scanning unit and an SD card on the detection jig, a different sorting number is given to each liquid cooling line and a corresponding record table is generated, thereby realizing automated data coordination. The detection results can be simply recorded in the table according to the serial number through the buttons on the control unit, thereby effectively improving the detection efficiency of the liquid cooling line.
