Description

Technical Field

[0001] This application relates to the field of cold plate testing technology, and in particular to a cold plate testing device. Background Technology

[0002] After production, cold-rolled steel plates undergo flow resistance and thermal resistance tests to verify whether the designed cold-rolled steel plates meet the set requirements. Currently, this is usually done by setting a fixed heating block for inspection. However, since the heating block has a fixed power, the heater power cannot be adjusted, and changing the type of cold-rolled steel plate also requires changing the corresponding heating block power and size, resulting in complex operation and low efficiency. Furthermore, temperature detection of the heating block is usually achieved by incorporating a temperature sensor inside the heating block. This method is complex to control and involves numerous cables, increasing the risk of short circuits or combustion during heating. Utility Model Content

[0015] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] To address the issue of low efficiency in testing the flow resistance and thermal resistance of cold plates in related technologies, this application provides a cold plate testing device.

[0017] like Figure 1 and Figure 2The cold plate testing device shown includes a heating component 10, a test pipeline 20, an adjustment component, a differential pressure detection component 40, and a temperature detection component 50. The heating component 10 is disposed at the cold plate 80 and exchanges heat with the cold plate 80. The test pipeline 20 is used to circulate liquid to the cold plate 80. The test pipeline 20 includes a common pipeline 21 and multiple detection pipelines 22. The detection pipelines 22 are connected to the common pipeline 21, and the detection pipelines 22 are arranged in parallel. The detection pipelines 22 have an inlet and an outlet for connecting with the cold plate 80. The adjustment component is disposed on the test pipeline 20 and is used to adjust the parameters of the refrigerant in the test pipeline 20. The differential pressure detection component 40 is disposed between the inlet and the outlet and is used to detect the pressure difference between the two ends of the cold plate 80. The temperature detection component 50 is used to detect the heating temperature of the heating component 10.

[0018] This embodiment utilizes a common pipeline 21 and a detection pipeline 22 for the test pipeline 20, with the detection pipelines 22 arranged in parallel. This allows each detection pipeline 22 to independently test the cold plate 80, significantly improving testing efficiency. Simultaneously, the inclusion of a heating component 10, an adjustment component, a differential pressure detection component 40, and a temperature detection component 50 enables the heating component 10 to heat and exchange heat with the cold plate 80 during testing, simulating component heating. The adjustment component adjusts the refrigerant parameters to a predetermined state. The differential pressure detection component 40 detects the pressure difference across the cold plate 80, determining whether a set differential pressure value has been reached. If the value is reached, the flow resistance test is passed; otherwise, it fails. The temperature detection component 50 determines whether the temperature of the heating component 10 has dropped to a set temperature. If the temperature is within the set range, the thermal resistance test is passed. This integrated flow resistance and thermal resistance testing functions saves equipment costs, simplifies the testing process, and increases testing efficiency.

[0019] It should be noted that the cold plate 80 used for testing can be any cold plate used on various devices. In this embodiment, the cold plate 80 on a server is used as an example. Specifically, it can be a cold plate from an image processor or a cold plate from a central processing unit, etc. The cold plates 80 can be divided into multiple sets, with multiple cold plates 80 set in each set. The cold plates 80 in each set are connected in series. Each detection pipeline 22 can be equipped with one set of cold plates 80, thereby allowing testing of multiple sets of cold plates 80. The number of detection pipelines 22 can be increased as needed, as long as it matches the number of cold plates 80 to be tested.

[0020] like Figure 2 As shown, each detection pipeline 22 and the devices installed on it in this embodiment adopt the same form. Of course, different forms can also be adopted as needed.

[0021] like Figure 1 As shown, in this embodiment, both the heating component 10 and the temperature detection component 50 employ a laser system. Specifically, the temperature detection component 50 includes a laser temperature measuring component, which detects the temperature of the heating block 11 of the heating component 10 within a certain distance using laser temperature measurement. The heating component 10 includes a heating block 11 and a laser heating element 12. The heating block 11 is configured to contact the cold plate 80 for heat transfer, and the heating block 11 is a component that directly contacts the cold plate 80 for heat exchange. The laser heating element 12 utilizes a high-energy laser beam to convert light energy into heat energy, thereby generating a high-temperature environment at the heating block 11 and achieving the effect of heating the heating block 11. A certain distance can be maintained between the laser heating element 12 and the heating block 11, thus enabling non-contact heating. The number of heating blocks 11 and laser heating elements 12 can be set as needed. When there are multiple cold plates 80, multiple heating blocks 11 can also be set, preferably in a one-to-one correspondence with the cold plates 80. In this case, since the laser heating element 12 can heat more than one heating block 11, the number of laser heating elements 12 can be set according to the number of heating blocks 11 they can cover. For example, taking the cold plate of an image processor as an example... Figure 3 As shown, each set of cold plates 80 consists of eight cold plates 80, which are connected together by a tube. Twenty laser heating elements 12 can meet the simultaneous testing of two sets of cold plates 80, so two detection pipes 22 can be allocated to test the thermal resistance of the cold plates 80; taking the cold plate of the central processing unit as an example, if... Figure 4 As shown, each set of cold plates 80 consists of two cold plates 80 connected together by a pipe. Twenty sets of laser heating elements 12 can simultaneously test ten sets of cold plates 80, thus allowing for the allocation of ten testing pipelines 22 for testing. This laser heating and testing method avoids the need for frequent replacement of heating blocks and heaters, simplifying the testing process and preventing complex cabling and the risk of fires caused by short circuits due to temperature.

[0022] like Figure 2As shown, in this embodiment, the test pipeline 20 also includes a storage tank 23. The common pipeline 21 is connected to the storage tank 23. The storage tank 23 is used to store refrigerant and provide refrigerant to the common pipeline 21 and the detection pipeline 22. The regulating component can also adjust parameters such as the temperature of the refrigerant in the storage tank 23. In this embodiment, the refrigerant can be water or a similar medium. The regulating component includes a heater 31, a water inlet pipeline 32, and a first sensor 33. The heater 31 can be a heating element or similar component, and it is installed inside the storage tank 23 to heat the refrigerant, thereby increasing the temperature of the refrigerant in the storage tank 23. One end of the water inlet pipeline 32 is connected to the storage tank 23, and the other end can be connected to an external water supply device, allowing refrigerant to be added to the storage tank 23 through the water inlet pipeline 32. This replenishment of refrigerant lowers its temperature, thus achieving the goal of reducing the refrigerant temperature. Valves and other components can be installed on the inlet pipe 32 as needed to control its opening and closing. A first sensor 33 is installed on the test pipe 20, more specifically on the common pipe 21, and is used to detect the temperature of the refrigerant within the test pipe 20. The first sensor 33 can be a temperature sensor or other components, and can be associated with the heater 31 and the valves on the inlet pipe 32. This allows the heater 31 and the inlet pipe 32 to adjust the refrigerant temperature based on the temperature detected by the first sensor 33, thus maintaining the refrigerant temperature within a predetermined range. When the temperature is too low, the heater 31 starts to heat the refrigerant; when the temperature is too high, the valve opens to allow cold water to enter the storage tank 23 to lower the temperature. This method of temperature adjustment using water replenishment eliminates the cost and bulk of increasing compressor cooling, resulting in a smaller device size and lower power consumption, significantly saving space and cost, and making it more widely applicable.

[0023] like Figure 2As shown, in this embodiment, the cold plate testing device further includes a water quality testing pipeline 61, a water quality testing component 62, and a delivery pump 63. Both ends of the water quality testing pipeline 61 are connected to the liquid storage tank 23, thus forming a roughly parallel connection between the water quality testing pipeline 61 and the liquid storage tank 23. The water quality testing component 62 is installed on the water quality testing pipeline 61. The refrigerant is delivered to the water quality testing component 62 via the water quality testing pipeline 61 for testing. The water quality testing component 62 can detect the quality of the refrigerant, thereby ensuring that the quality of the refrigerant meets the requirements. The water quality testing component 62 includes at least one of an acidity / alkalinity sensor, a conductivity sensor, and a turbidity sensor. This embodiment simultaneously provides all three sensors, thereby enabling the detection of the acidity / alkalinity, conductivity, and turbidity of the refrigerant. The transfer pump 63 is installed on the water quality testing pipeline 61. The transfer pump 63 is used to provide power for the refrigerant to be transported to the water quality testing component 62, so that the refrigerant in the storage tank 23 can enter the water quality testing component 62 under the action of the transfer pump 63, and be transported back to the storage tank 23 after testing, thus avoiding waste.

[0024] like Figure 2 As shown, in this embodiment, the cold plate testing device further includes an automatic drain pipe 71, a manual drain pipe 72, and an overflow pipe 73. The automatic drain pipe 71 is connected to the liquid storage tank 23 and / or the common pipe 21, and is equipped with an automatic valve and a drain pump. Similarly, the manual drain pipe 72 is connected to the liquid storage tank 23 and / or the common pipe 21, and is equipped with a manual valve. The automatic drain pipe 71 and the manual drain pipe 72 enable automatic and manual draining of the test pipe 20, allowing the refrigerant to be discharged automatically or manually during long-term non-use or cleaning. One end of the overflow pipe 73 is connected to the top of the liquid storage tank 23, and the other end of the overflow pipe 73 is connected to the outlet of the automatic drain pipe 71 and / or the manual drain pipe 72. This allows excess refrigerant in the liquid storage tank 23 to be automatically drained through the overflow pipe 73, preventing overflow. A liquid level sensor can also be installed inside the liquid storage tank 23, with sensors placed at both the low and high positions to detect the liquid level.

[0025] In this embodiment, a Y-type filter is installed on the common pipeline 21. The other end of the Y-type filter is connected to the outlet section of the automatic drainage pipeline 71 through a pipeline. A valve is also installed on this pipeline to control its opening and closing.

[0026] like Figure 2As shown, in this embodiment, the regulating component includes a pump body 34 and a second sensor 35. The pump body 34 is installed on the common pipeline 21 and drives the refrigerant to flow in the test pipeline 20. The pumping volume of the pump body 34 is adjustable, and the flow rate in the test pipeline 20 can be adjusted by adjusting the pumping volume of the pump body 34. The second sensor 35 is installed on the common pipeline 21 and electrically connected to the pump body 34. The second sensor 35 is used to detect the flow rate of the common pipeline 21. It can be a flow sensor, an ultrasonic flow meter, or other components, so that the second sensor 35 can be correlated with the pump body 34. The pump body 34 can adjust the pumping volume according to the flow rate detected by the second sensor 35, so that the refrigerant flow rate in the common pipeline 21 can be maintained within a predetermined range.

[0027] In this embodiment, the regulating assembly further includes a control valve 36 and a third sensor 37. The control valve 36 is disposed on the detection pipeline 22, and the flow rate and pressure of the detection pipeline 22 can be controlled by adjusting the opening degree of the control valve 36. The third sensor 37 is disposed on the detection pipeline 22 and electrically connected to the control valve 36. The control valve 36 can be a linear electric proportional valve, and the third sensor 37 can be an ultrasonic flow meter. The third sensor 37 is associated with the control valve 36, so that the control valve 36 can adjust the flow rate and pressure of the detection pipeline 22 according to the flow rate and pressure detected by the third sensor 37, so that the pressure and flow rate in the detection pipeline 22 are within a predetermined range. Since this embodiment has multiple detection pipelines 22, multiple control valves 36 and third sensors 37 are also provided. Each detection pipeline 22 is equipped with a control valve 36 and a third sensor 37. In this way, the flow rate and pressure of each detection pipeline 22 can be adjusted by the control valve 36 and the third sensor 37 on each detection pipeline 22, so that the detection process between the detection pipelines 22 is independent of each other, and the detection of each set of cold plates 80 does not affect each other, thus ensuring the accuracy of the detection results.

[0028] In this embodiment, the adjustment component also includes a fourth sensor 38, which is disposed on the detection pipe 22 and used to detect the temperature of the refrigerant in the detection pipe 22. The fourth sensor 38 can be a temperature sensor. The fourth sensor 38 is disposed at the end of the detection pipe 22 that connects to the common pipe 21. In this embodiment, the fourth sensor 38 is disposed at both ends of the detection pipe 22, so that the temperature of the refrigerant before and after entering the cold plate 80 can be detected by the fourth sensor 38 at both ends, thereby obtaining the temperature difference of the refrigerant at both ends of the cold plate 80. Since the first sensor 33 makes the temperature of the water inlet of the cold plate 80 basically constant, the return water temperature detected by the fourth sensor 38 at the outlet end is mainly used to measure the thermal resistance performance of the cold plate 80. That is to say, during the flow resistance test, the return water temperature detected by the fourth sensor 38 and the temperature of the heating block 11 detected by the temperature detection component 50 are taken into account at the same time. When the return water temperature and the surface temperature of the heating block 11 are both within the set range, the thermal resistance test is qualified. This test is more comprehensive and the results are more stable and reliable.

[0029] In this embodiment, the regulating component also includes a switching valve 39, which can be an electric ball valve or the like. Switching valves 39 are installed on both the common pipeline 21 and the detection pipeline 22, and are used to control the opening and closing of the common pipeline 21 and the detection pipeline 22. In this embodiment, a switching valve 39 is installed on each side of the Y-type filter, and a switching valve 39 is also installed in the liquid inlet section of the detection pipeline 22, thereby achieving overall opening and closing control of the test pipeline 20.

[0030] In this embodiment, quick-release self-sealing connectors are provided at the inlet and outlet of the detection pipeline 22. Correspondingly, quick-release self-sealing connectors are also provided on the cold plate 80. The cold plate 80 can be quickly installed on the detection pipeline 22 through the mating of these quick-release self-sealing connectors, which is convenient and fast. After the cold plate 80 is installed on the detection pipeline 22, it forms a parallel connection with the differential pressure detection component 40, thereby enabling the detection of the pressure difference across the two ends of the cold plate 80. The differential pressure detection component 40 can use a differential pressure sensor as needed.

[0031] In this embodiment, a pressure sensor is also installed on the common pipeline 21. The pressure sensor is used as a safety component and can monitor the current pressure in real time. When the pressure reaches the alarm set value, the equipment will alarm and stop operating to prevent damage to the pump group.

[0032] The specific testing method of the cold plate testing device in this embodiment is as follows:

[0033] Step 1: Connect the cold plate 80 to the cold plate testing device. Connect the two ends of the cold plate 80 to the liquid inlet and the liquid outlet, respectively.

[0034] Step 2: Set the cold plate parameters on the host computer, including cold plate size, cold plate working flow rate, pressure difference value, inlet and outlet water temperature, etc.

[0035] Step 3: The equipment is started, the switch valve 39 on the detection pipeline 22 is opened, the equipment automatically adjusts the pump body 34 according to the allowable flow rate of the cold plate 80 set by the host computer, and the flow rate feedback is obtained through the second sensor 35. When the flow rate reaches the set value, the frequency of the pump body 34 will be fixed. The host computer will automatically increase the flow rate set value according to the number of detection pipelines 22 to meet the flow rate of each detection pipeline 22. Each detection pipeline 22 adjusts the flow rate through its own control valve 36 to ensure that the flow rate of each detection pipeline 22 meets the usage requirements. The flow rate is detected by the third sensor 37 of each detection pipeline 22.

[0036] Step 4: The differential pressure sensor of each detection pipeline 22 detects whether the differential pressure value between the two ends of the cold plate 80 reaches the set differential pressure value. If it reaches the set differential pressure value, the flow resistance test is qualified; if it is not within the differential pressure value range, the flow resistance test is unqualified.

[0037] Step 5: After the flow resistance test is completed, start the heater 31 to heat the refrigerant. Stop heating when the set temperature is reached. If the temperature exceeds the set range, replenish water to the storage tank 23 through the water inlet pipe 32 to lower the temperature to the set range. When the cold plate 80 is tested for thermal resistance, the refrigerant temperature will gradually increase due to heat dissipation from the cold plate 80. At this time, it is necessary to regulate the water temperature by draining and replenishing water in the storage tank 23 to keep the temperature within the set range.

[0038] Step 6: Based on the cold plate parameters set by the host computer, determine the number of cold plates and allocate the number of detection pipes 22 and heating components 10;

[0039] Step 7: The laser heating element 12 distributes the heating area according to the size of the cold plate 80 to heat the heating block 11. The upper part of the heating block 11 contacts the cold plate 80 for heat exchange. The cold plate 80 carries away the heat of the heating block 11 through the circulating water system. The return water temperature is detected by the fourth sensor 38 to see if it is within the set range. The surface temperature of the heating block 11 is detected by the temperature detection component 50 to see if the temperature drops to the set temperature. If the return water temperature and the surface temperature of the heating block 11 are within the set range, the thermal resistance test is qualified.

[0040] It should be noted that "multiple" in the above embodiments refers to at least two.

[0041] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0042] By using a common pipeline 21 and a detection pipeline 22 for the test pipeline 20, and arranging the detection pipelines 22 in parallel, each detection pipeline 22 can independently test the cold plate 80, thus greatly improving testing efficiency. Simultaneously, with the setup of the heating component 10, adjustment component, differential pressure detection component 40, and temperature detection component 50, during testing, the heating component 10 heats and exchanges heat with the cold plate 80, simulating component heating. The adjustment component adjusts the refrigerant parameters to a predetermined state. The differential pressure detection component 40 detects the pressure difference across the cold plate 80, determining whether a set differential pressure value has been reached. If the value is reached, the flow resistance test is passed; otherwise, it fails. Simultaneously, the temperature detection component 50 determines whether the temperature of the heating component 10 has dropped to a set temperature. If the temperature is within the set range, the thermal resistance test is passed. This device integrates flow resistance and thermal resistance testing functions, saving equipment costs, simplifying the testing process, and increasing testing efficiency.

[0043] The above provides a detailed description of a cold plate testing device provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
