Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments.

In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0056] Next, a thermal performance detection system for a liquid-cooled radiator according to an embodiment of the present utility model is described.

[0057] like Figure 1 and Figure 2 As shown, the thermal performance detection system of the liquid cooling radiator of the embodiment of the utility model includes a water tank 610, a water pump 620, a metal block 410, a heating rod 420, a power regulator, a controller, a thermocouple and a data display. The surface of the liquid cooling radiator 500 is formed with an installation area, and the installation area is used to connect the object to be cooled.

[0058] First, the water tank 610 and the water pump 620 are described. The water tank 610 can contain cooling liquid, and the liquid inlet of the water tank 610 is connected to the liquid outlet of the liquid cooling radiator 500. The liquid inlet of the water pump 620 is connected to the liquid outlet of the water tank 610, and its liquid outlet is connected to the liquid inlet of the liquid cooling radiator 500.

[0059] That is to say, the water pump 620 can extract the coolant in the water tank 610 to circulate and dissipate heat in the liquid-cooled radiator 500 , thereby simulating the situation where the coolant flows in the liquid-cooled radiator 500 .

[0060] Next, the metal block 410, the heating rod 420, the power regulator and the controller are described. The metal block 410 is used to connect to the mounting area of ​​the liquid cooling radiator 500, and a mounting hole is formed in the horizontal direction of the metal block 410. The heating rod 420 is inserted into the mounting hole of the metal block 410. The power regulator is connected to the heating rod 420. The controller is connected to the power regulator so that the power regulator outputs a predetermined power.

[0061] like Figure 2 As shown, the metal block 410 is used to simulate the object to be cooled, and the controller controls the power regulator to provide a predetermined power to the heating rod 420, so that the heating rod 420 can generate heat, and this heat can be transferred to the metal block 410, thereby simulating the heating of the object to be cooled during operation. By setting metal blocks 410 of different sizes and / or setting different powers, various conditions of the object to be cooled can be simulated.

[0062] The metal block 410 is connected to the installation area of ​​the liquid-cooled radiator 500 , so as to simulate the connection between the object to be cooled and the liquid-cooled radiator 500 .

[0063] Next, the thermocouple and the data display are described. The thermocouple is connected to the metal block 410 to test the temperature of the metal block 410. The data display is connected to the thermocouple to display the data of the thermocouple.

[0064] The temperature of the metal block 410 can be acquired through a thermocouple, so that the temperature of the metal block 410 when cooled by the liquid-cooled radiator 500 can be detected. Based on this temperature, it can be determined whether the heat dissipation performance of the liquid-cooled radiator 500 meets the requirements.

[0065] The temperature detected by the thermocouple can be clearly displayed on the display, so that relevant personnel can promptly determine whether the liquid cooling radiator 500 meets the requirements.

[0066] In the above thermal performance detection system of the liquid-cooled radiator, the water pump 620 extracts the coolant from the water tank 610 to circulate and cool the liquid-cooled radiator 500, the metal block 410 simulates the object to be cooled, the controller controls the power regulator to output a predetermined power to the heating rod 420, the heating rod 420 is inserted into the metal block 410, so that the temperature of the metal block 410 increases, the metal block 410 is connected to the liquid-cooled radiator 500, the liquid-cooled radiator 500 cools the metal block 410, the temperature of the metal block 410 is detected by a thermocouple, and the temperature detected by the thermocouple is displayed by a data display. Based on this temperature, it can be determined whether the liquid-cooled radiator 500 meets the heat dissipation requirements for the metal block 410, that is, it can be determined whether the thermal performance of the liquid-cooled radiator 500 meets the requirements, and the detection efficiency is high, the cost is low and the accuracy is high.

[0067] In some embodiments of the utility model, the thermal performance detection system also includes a crimping device, which includes a bottom plate 110, a top plate 120, two screw rods 140, two sets of nuts 130 and a pressing assembly 200. The bottom plate 110 can carry a liquid-cooled radiator 500. The top plate 120 is located above the bottom plate 110. The two screw rods 140 are arranged at intervals, and the top end of each screw rod 140 passes through the top plate 120, and the bottom end thereof is fixedly connected to the bottom plate 110. The two sets of nuts 130 are respectively connected to the two screw rods 140 in a one-to-one correspondence, and each set of nuts 130 includes nuts 130 respectively located on the upper and lower sides of the top plate 120, and the nuts 130 surround the screw rods 140 and are threadedly connected to the screw rods 140. The pressing assembly 200 includes a pressing body and a movable part. The pressing body is disposed at the bottom of the top plate 120 . The movable part can be raised and lowered. The movable part can press down the metal block 410 so that the metal block 410 abuts against the liquid cooling radiator 500 .

[0068] For example, when testing the liquid-cooled radiator 500, the liquid-cooled radiator 500 is placed on the bottom plate 110, and the metal block 410 is placed on the upper surface of the liquid-cooled radiator 500. The two sets of nuts 130 (four nuts) are rotated so that the two sets of nuts 130 are respectively lowered on the two screws 140, so that the top plate 120 located between the two sets of nuts 130 is lowered, and the top plate 120 drives the lower pressure assembly 200 connected thereto to lower, that is, the adjustment of the detection height is achieved by adjusting the two sets of nuts 130 (adjusted according to the height of different liquid-cooled radiators 500, so that different liquid-cooled radiators 500 can be inserted, and the movable part of the lower pressure assembly 200 can abut against the metal block 410), so that the bottom of the lower pressure assembly 200 has a predetermined gap from the liquid-cooled radiator 500. The lower pressure device can be a cylinder, a hydraulic cylinder, an electric cylinder or a motor.

[0069] The controller can control the movable part of the pressing assembly 200 to descend, so that the movable part abuts against the metal block 410, so that the metal block 410 and the liquid cooling radiator 500 are clamped, and the thermal resistance between the metal block 410 and the liquid cooling radiator 500 is reduced. In this way, it is possible to simulate the situation that the object to be cooled and the liquid cooling radiator 500 are tightly connected by fasteners or welding, increase the accuracy of the detection, and facilitate disassembly, which is relatively simple and has a high detection efficiency.

[0070] Furthermore, the crimping device further includes a first wooden board 310 and a second wooden board 320. The lower surface of the first wooden board 310 is connected to the metal block 410, and the upper surface of the first wooden board 310 faces the pressing assembly 200, and the movable part can abut the metal block 410 through the first wooden board 310. The second wooden board 320 is arranged on the upper surface of the bottom plate 110, and the bottom plate 110 carries the liquid cooling radiator 500 through the second wooden board 320.

[0071] The hardness of the wooden board is lower than that of other metal materials of the crimping device. The impact of the pressing assembly 200 on the metal block 410 and the liquid cooling radiator 500 can be reduced by the first wooden board 310 and the second wooden board 320, thereby reducing damage. Moreover, the thermal conductivity of the wooden board is lower than that of metal. Using the wooden board to contact the metal block 410 and the liquid cooling radiator 500 can reduce the influence of the crimping device on the heat dissipation of the metal block 410, so that the cooling of the metal block 410 is concentrated on the liquid cooling radiator 500, reducing interference in the detection process and increasing the accuracy of the detection.

[0072] Furthermore, the crimping device further includes a pressure sensor. The top end of the pressure sensor is arranged at the bottom end of the movable part of the pressing assembly 200, and the pressing assembly 200 is connected to the first wooden board 310 through the pressure sensor. The controller also connects the pressure sensor and the pressing assembly 200 so that the pressure detected by the pressure sensor is at a predetermined pressure.

[0073] The controller controls the movable part of the pressing assembly 200 to descend and abut against the metal block 410. As the movable part of the pressing assembly 200 continues to descend, the pressure detected by the pressure sensor rises, and when the predetermined pressure is reached, the controller controls the movable part of the pressing assembly 200 to stop descending. In this way, it is possible to avoid over-pressing the pressing assembly 200 and causing damage to the metal block 410 and the liquid cooling radiator 500, and it is possible to avoid under-pressing the pressing assembly 200 and causing excessive contact thermal resistance between the metal block 410 and the liquid cooling radiator 500, thereby increasing the accuracy of thermal performance detection.

[0074] In some embodiments of the utility model, the metal block 410 includes multiple pieces, and the crimping device also includes multiple thermal grease sheets. The multiple thermal grease sheets correspond one-to-one to the metal blocks 410. The thermal grease sheets are arranged on the surface of the metal block 410 facing the liquid-cooled radiator 500. Part of the metal block 410 is connected to the lower surface of the first wooden board 310, and the other part of the metal block 410 is connected to the upper surface of the second wooden board 320. The second wooden board 320 supports the liquid-cooled radiator 500 through the metal block 410 and the thermal grease sheets.

[0075] That is, from bottom to top, it includes the bottom plate 110, the second wooden board 320, a portion of the metal block 410, a portion of the thermal conductive silicone grease sheet (solid), the liquid cooling radiator 500, another portion of the thermal conductive silicone grease sheet (solid), another portion of the metal block 410, and the first wooden board 310. That is, it is possible to simulate the double-sided heat dissipation of the liquid cooling radiator 500, thereby increasing the versatility of the detection system.

[0076] By using a thermal grease sheet (solid) to simulate the fluid thermal grease between the actual object to be cooled and the liquid cooling radiator 500, the consumption of the fluid thermal grease is reduced, the cost is reduced, and the process of manually applying the fluid thermal grease is avoided, thereby improving the efficiency of thermal performance testing.

[0077] In some embodiments of the present invention, the thermal performance detection system further includes a heating device 650 and a refrigeration device. The heating device 650 is inserted into the water tank 610 to heat the coolant in the water tank 610. The first end of the refrigeration device is used to connect the liquid cooling radiator 500, and the second end thereof is connected to the liquid inlet end of the water tank 610, and the liquid outlet end of the liquid cooling radiator 500 is connected to the liquid inlet end of the water tank 610 through the refrigeration device.

[0078] like Figure 1 As shown, the heating device 650 heats the coolant in the water tank 610, and the refrigeration device cools the coolant flowing out of the liquid-cooled radiator 500, and flows the cooled coolant into the water tank 610. The heating device 650 and the refrigeration device can control the temperature of the coolant in the water tank 610, thereby providing the coolant of a predetermined temperature to the liquid-cooled radiator 500, so that the liquid-cooled radiator 500 can continuously cool the metal block 410. In this way, it is possible to easily simulate the situation of the coolant of a predetermined temperature flowing inside the liquid-cooled radiator 500 during the actual operation of the liquid-cooled radiator 500, thereby increasing the accuracy of the thermal performance detection.

[0079] Furthermore, the thermal performance detection system further includes a water tank temperature sensor. The water tank temperature sensor is connected to the water tank 610 to detect the first temperature of the coolant in the water tank 610. The controller is also connected to the water tank temperature sensor, the heating device 650 and the refrigeration device to control the operation of the heating device 650 and the refrigeration device according to the first temperature detected by the water tank temperature sensor so that the first temperature is a predetermined temperature.

[0080] For example, the controller controls the heating device 650 and the cooling device so that the temperature of the coolant in the water tank 610 detected by the water tank temperature sensor is 30 degrees, 40 degrees, and 50 degrees, respectively, and obtains the temperature of the metal block 410. In this way, it can be determined whether the thermal performance of the liquid-cooled radiator 500 meets the requirements under different coolant temperatures.

[0081] Optionally, the refrigeration device includes a heat exchanger 661, a compressor 662, a condenser 663, a filter 664 and an expansion valve 665. The heat exchanger 661 includes a first channel and a second channel adjacent to each other, and the two ends of the first channel are respectively connected to the liquid outlet of the water pump 620 and the liquid inlet of the water tank 610. The compressor 662 is connected to the first end of the second channel of the heat exchanger 661, and the compressor 662 contains a refrigerant and can compress the refrigerant. The condenser 663 is connected to the compressor 662. The filter 664 is connected to the condenser 663. The first end of the expansion valve 665 is connected to the filter 664, and the second end thereof is connected to the second end of the second channel of the heat exchanger 661.

[0082] like Figure 1 As shown, the compressor 662 compresses the refrigerant to form a high-temperature and high-pressure gaseous refrigerant. The gaseous refrigerant passes through the condenser 663 to form a liquid refrigerant. The liquid refrigerant passes through the filter 664 to remove impurities and enters the expansion valve 665. The controller controls the opening of the expansion valve 665 to allow a predetermined amount of liquid refrigerant to form a mist refrigerant and enter the second channel of the heat exchanger 661, thereby cooling the second channel. The low temperature of the second channel is transmitted to the first channel of the heat exchanger 661, thereby cooling the coolant in the first channel. In this way, the coolant can be easily cooled, the cooling efficiency is high, the external temperature fluctuation is small, and the temperature control accuracy is good, thereby making the temperature control of the coolant temperature more accurate and reducing the error of thermal performance detection.

[0083] In some embodiments of the present invention, the thermal performance detection system further includes an inlet manifold 631, an outlet manifold 632, an inlet temperature sensor 641, and at least one outlet temperature sensor 643. The first end of the inlet manifold 631 is connected to the water pump 620, and the second end thereof is formed with at least one first joint for connecting to the inlet end of the liquid-cooled radiator 500, and the water pump 620 is connected to the liquid-cooled radiator 500 through the inlet manifold 631. The first end of the outlet manifold 632 is formed with at least one second joint for connecting to the outlet end of the liquid-cooled radiator 500, and the second end thereof is connected to the refrigeration device, and the refrigeration device is connected to the outlet end of the liquid-cooled radiator 500 through the outlet manifold 632. The inlet temperature sensor 641 is connected to the inlet manifold 631 to detect the second temperature of the coolant in the inlet manifold 631. The liquid outlet temperature sensor 643 is connected to the second joint of the liquid outlet manifold 632 to detect the third temperature of the coolant in the second joint.

[0084] like Figure 2 As shown, the thermal performance test of two liquid cooling radiators 500 can be performed simultaneously through the liquid inlet manifold 631 and the liquid outlet manifold 632, thereby increasing the test efficiency. It should be noted that the above are only optional examples, and the thermal performance test of three, five, etc. liquid cooling radiators 500 can also be performed simultaneously, which should be understood to be within the scope of the present invention.

[0085] The temperature of the coolant that is about to enter the liquid cooling radiator 500 can be detected by the liquid inlet temperature sensor 641, and the temperature of the coolant flowing out of each liquid cooling radiator 500 can be detected by at least one liquid outlet temperature sensor 643. The number of the liquid outlet temperature sensors 643 corresponds to the number of the liquid cooling radiators 500 to be detected simultaneously.

[0086] Based on this, the thermal resistance and the temperature rise can be calculated, thermal resistance = (first temperature - second temperature) / power of the power regulator, temperature rise = third temperature - first temperature.

[0087] Therefore, the thermal resistance and temperature rise can be added to evaluate the thermal performance of the liquid-cooled radiator, thereby increasing the comprehensiveness of the thermal performance judgment of the liquid-cooled radiator 500 .

[0088] Furthermore, the thermal performance detection system further includes a liquid inlet pressure sensor 642 and a liquid outlet pressure sensor 644. The liquid inlet pressure sensor 642 is connected to the liquid inlet manifold 631 to detect a first pressure of the coolant in the liquid inlet manifold 631. The liquid outlet pressure sensor 644 is connected to the liquid outlet manifold 632 to detect a second pressure of the coolant in the liquid outlet manifold 632.

[0089] By subtracting the first pressure from the second pressure, the pressure drop of the coolant can be calculated. The pressure drop can affect the thermal performance of the liquid cooling. When the thermal performance test fails, the pressure drop can be used to determine whether the thermal performance of the liquid cooling radiator 500 is caused by the pressure drop, which can facilitate the analysis of the thermal performance of the liquid cooling radiator.

[0090] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
