Description

Technical Field

[0001] The invention relates to the technical field of air pressure detection devices for liquid cooling plates, and in particular to an automatic loading and unloading type air pressure detection device for liquid cooling plates. Background Art

[0002] Liquid cooling plates play a core role in many fields with high heat dissipation requirements. They efficiently absorb and remove heat through circulating coolant, achieve precise temperature control, reduce operating noise, and improve space utilization. Its customizable design meets the requirements of different equipment and heat dissipation, and can be combined with other heat dissipation methods to form an efficient heat dissipation system. In addition, liquid cooling plates are energy-saving and environmentally friendly, which helps to reduce energy consumption and reduce the impact on the environment. In fields such as data centers, high-performance computing, electric vehicles, and LED lighting, liquid cooling plates have become an indispensable heat dissipation solution. Once the coolant in the liquid cooling plate leaks, it may come into contact with the electronic components and circuits inside the equipment, causing a short circuit. This will not only damage these components and circuits, but may also cause serious consequences such as fire.

[0003] Therefore, many manufacturers will test the sealing of liquid cooling plates, usually by air pressure testing. At present, although the air pressure testing devices for liquid cooling plates on the market can test the sealing of liquid cooling plates, they require manual wiring and loading and unloading, which is not only difficult to test in batches, but also increases the time and labor cost of testing. Moreover, when there is a problem with the sealing of the liquid cooling plate, it is difficult for the existing air pressure testing devices to accurately locate and quickly find the leakage point. Summary of the invention

[0004] The object of the present invention is to provide an air pressure detection device for an automatic loading and unloading liquid cooling plate to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: an air pressure detection device for an automatic loading and unloading liquid cooling plate, comprising a detection base and a gantry, a control box is arranged on one side of the detection base, a transmission device is arranged on one end of the detection base, a sealing detection device is installed on the detection base, a unloading assembly and a loading assembly are installed on the sealing detection device, a hydraulic device is installed on the gantry, the hydraulic device is connected to the sealing detection device, an air supply device is installed in the detection base, and the sealing detection device and the air supply device are connected through a pipeline; the sealing detection device comprises an upper pressure plate and a lower pressure plate, both of which are provided with a positioning device, the positioning device installed on the upper pressure plate is connected to the hydraulic device, a first transmission assembly and a second transmission assembly are installed between the upper pressure plate and the lower pressure plate, a unloading assembly is installed on the top of the lower pressure plate, a loading assembly is installed on the bottom of the lower pressure plate, a correction assembly and a sliding joint are slidably installed on the lower pressure plate, the sliding joint is meshed with the first transmission assembly for transmission, and the correction assembly is meshed with the second transmission assembly for transmission.

[0006] A control system is installed in the control box, and the control system is used to control the entire air pressure detection device; the air supply device is used to transport detection gases of various temperatures to the liquid cooling plate.

[0007] The control system controls the transmission device to transport the liquid cooling plate to be inspected to a preset position, and then turns on the second electric telescopic rod. The output shaft of the second electric telescopic rod drives the loading block on the steering motor to extend. After the loading block passes through the gap between the transmission devices, the control system turns on the steering motor, and the output shaft of the steering motor drives the loading block to rotate 90 degrees so that the loading block is against the end of the liquid cooling plate. The output shaft of the second electric telescopic rod is pulled back, so that the loading block drives the liquid cooling plate to slide until the other end of the liquid cooling plate is against the lower block in the contracted state. Then the control system turns on the hydraulic device, and the hydraulic device drives the sealing detection device to descend.

[0008] The positioning device includes a side frame, which is respectively mounted on the upper pressure plate and the lower pressure plate, and a plurality of positioning mark components are installed in the side frame, a sealing cover is installed on the side frame, and a suction interface is installed on one side of the side frame, and the suction interface is connected to an air pump through a pipeline. The gap between the side frame, the sealing cover and the positioning mark component forms a suction chamber, and the suction interface is connected to the inside of the suction chamber. The air pump removes the gas in the suction chamber from the suction interface through the pipeline, so that a negative pressure is formed in the suction chamber.

[0009] The positioning mark assembly includes a detection frame and a detection connecting rod. A positioning cover is installed on the detection frame, a cone is installed on the positioning cover, a detector is installed on the detection frame through the detection connecting rod, a detection screw is rotatably installed in the detector, a blade joint is installed on the detection screw, a number of temperature sensing blades are obliquely installed on the blade joint, and a limit groove is provided in the cone.

[0010] Several detection frames divide the surface of the liquid cooling plate into several detection areas. In normal state, the limit groove in the cone limits the rotation of the temperature sensing blade. When the inclined temperature sensing blade rotates under the influence of airflow, it will be stuck in the limit groove and cannot rotate. The bottom of the detection frame is designed with a bevel surface to reduce the contact area with the liquid cooling plate, and the leaking gas is not blocked by the bottom of the detection frame.

[0011] After the sealing joint is connected, the control system controls the air supply device to inflate air into the liquid cooling plate through the sealing joint and controls the inflation speed. Within the preset time, the air pressure inside the liquid cooling plate is converted into an electrical signal through the pressure sensor in the sealing joint and transmitted to the control system. The control system determines the sealing of the liquid cooling plate by analyzing the electrical signal. When the air pressure reaches the preset value, the surface of the liquid cooling plate is well sealed. When the air pressure obviously does not reach the preset value, the surface of the liquid cooling plate is not well sealed and there is leakage.

[0012] The detector includes a detection shell, in which a detection screw is rotatably installed, the detection shell is connected to the detection frame through a detection connecting rod, a push block is slidably installed in the detection shell, the push block is threadedly connected to the detection screw, a positioning connecting rod is installed at the bottom end of the push block, a marking seal is installed at the bottom end of the positioning connecting rod, an alarm is concentrically installed with the marking seal, and a spring door is installed at the bottom end of the detection shell; the alarm includes an alarm shell, the alarm shell is concentrically connected with the marking seal, a sensing head is slidably installed in the alarm shell, a pressure spring is installed between the sensing head and the alarm shell, and a piezoelectric element is installed in the alarm shell.

[0013] When there is an obvious sealing problem with the liquid cooling plate, the control system controls the air supply device to continuously fill the liquid cooling plate with high-temperature and high-pressure gas, and at the same time turns on the air pump to form a negative pressure in the vacuum chamber and generate suction. The gas in the detection frame flows into the vacuum chamber and is extracted. At this time, the high-temperature gas that penetrates from the surface of the liquid cooling plate will flow from the detection frame to the cone cylinder, and then enter the negative pressure vacuum chamber from the cone cylinder. The high-temperature gas passing through the cone cylinder will gradually converge to the top of the cone cylinder and contact the temperature sensing blade, causing the temperature sensing blade to heat up. The temperature sensing blade heats up and deforms, and then is driven by the airflow to start rotating. The temperature sensing blade drives the detection screw to rotate, and the rotation of the detection screw drives the propulsion block to rotate. Since the propulsion block is slidably connected to the detection shell, it cannot rotate, thereby converting the rotation into When sliding downward in the detection shell, the push block drives the marking stamp to slide down through the positioning connecting rod, and the marking stamp drives the alarm to break through the spring door. The sensing head on the alarm first slides down and contacts the liquid cooling plate. The sensing head is pressurized and overcomes the elastic force of the pressure spring to slide upward relative to the alarm shell. The sensing head slides upward and squeezes the piezoelectric element. The piezoelectric element is pressurized to generate an electrical signal. The control system converts the electrical signal into an alarm signal and sends the alarm signal to the staff. Then the marking stamp continues to fall and contacts the surface of the liquid cooling plate. The marking stamp marks the surface of the liquid cooling plate. The staff finds the corresponding detection area according to the marked point. By inspecting the surface of the liquid cooling plate in the area, the leakage point can be quickly found, and the cause of the leakage can be analyzed.

[0014] After the inspection is completed, the control system repeats the previous operation in reverse to reset the upper pressure plate and remove the positioning constraint on the liquid cooling plate. The control system turns on the first electric telescopic rod, and the output shaft of the first electric telescopic rod drives the unloading block to extend. The unloading block pushes the inspected liquid cooling plate to the transmission device to complete the unloading. If the inspected liquid cooling plate has a sealing problem, the staff will reset the positioning mark component corresponding to the leakage area and repeat the above operations to realize automatic loading and unloading inspection of the liquid cooling plate.

[0015] The temperature sensing blade includes a first blade and a second blade, the first blade is connected to the second blade, the first blade and the second blade are both connected to a blade joint, the first blade and the second blade are both made of materials with large thermal expansion coefficients, and the thermal expansion coefficient of the second blade is greater than that of the first blade.

[0016] The first blade and the second blade are pressed together. When the first blade and the second blade are heated, thermal deformation will occur. At this time, the second blade with a high thermal expansion coefficient will bend toward the first blade with a low thermal expansion coefficient. Due to the overall bending deformation of the temperature-sensing blade, the distance between the temperature-sensing blade and the cone increases, causing the temperature-sensing blade to break away from the contact with the limit groove, allowing the temperature-sensing blade to rotate with the airflow.

[0017] The first transmission assembly includes a transmission screw and a gasket. The transmission screw is slidingly connected to the upper pressure plate and the lower pressure plate respectively. A first rod cap is installed on the top of the transmission screw. A downward pressure spring is installed between the first rod cap and the upper pressure plate. The gasket is installed on the lower pressure plate. A transmission gear is rotatably installed on the gasket. The transmission gear is threadedly connected to the transmission screw, and the transmission gear is threadedly connected to the sliding joint.

[0018] When the sealing detection device descends, it drives the upper pressure plate to be pressed down, and the upper pressure plate drives the first transmission assembly and the second transmission assembly to slide down. The upper pressure plate drives the transmission screw to descend through the downward pressure spring, and the transmission screw descends and squeezes the transmission gear, so that the transmission gear rotates on the gasket, and the transmission gear rotates, so that the second transmission assembly drives the sliding rack to slide toward the liquid cooling plate, and the sliding rack drives the side pressure slide bar to slide through the side pressure spring, and the side pressure slide bar drives the correction rod to slide, and the correction rods on both sides drive the liquid cooling plate to deviate toward the middle, so that the liquid cooling plate is located in the middle position of the lower pressure plate, thereby achieving the function of automatic correction and positioning, and meeting the correction and positioning of the liquid cooling plate of the specification size. Afterwards, as the upper pressure plate continues to descend, the correction rod further clamps the liquid cooling plate. When it reaches the critical point, the correction rod stops moving and further moves the sliding rack. At this time, since the correction rod and the side pressure slide bar cannot move, the sliding rack drives the side pressure spring to lengthen, thereby preventing the sliding rack from continuing to drive the correction rod to move and causing excessive extrusion on both sides of the liquid cooling plate, thereby achieving the purpose of self-protection. By the same token, the first transmission assembly drives the sliding tooth block to slide toward the liquid cooling plate, so that the sealing joint is docked with the water inlet and outlet of the liquid cooling plate after the deviation correction is completed, and then the upper pressure plate continues to descend. When the sliding tooth block and the sliding rack are unable to move due to the large size of the liquid cooling plate, the lower pressure plate will drive the downward pressure spring to lengthen, so that when the lower pressure plate continues to move downward, it will not drive the first transmission assembly and the second transmission assembly to move downward, thereby preventing the liquid cooling plate from being damaged by excessive squeezing, until the positioning device fits with the surface of the liquid cooling plate, thereby realizing automatic deviation correction and full-angle positioning of liquid cooling plates of different sizes, and realizing automatic docking of sealing joints and pressure overload protection.

[0019] The sliding joint includes a sliding gear block and an auxiliary gear. The sliding gear block is slidably connected to the lower pressure plate. The auxiliary gear is rotatably installed on the lower pressure plate. The sliding gear block is meshed with the transmission gear and the auxiliary gear respectively. A sealing joint is installed at one end of the sliding gear block, and an air pipe joint is installed at the other end of the sliding gear block. The air pipe joint is connected to the air supply device through a pipeline. A pressure sensor is provided in the sealing joint to detect the air pressure inside the liquid cooling plate.

[0020] The correction component includes a sliding rack and a limit block. The sliding rack is slidably connected to the lower pressure plate, the sliding rack is meshed with the second transmission component for transmission, a side pressure slide bar is slidably installed on the sliding rack, a second rod cap is installed at one end of the side pressure slide bar, a side pressure spring is installed between the second rod cap and the sliding rack, a correction rod is installed at the other end of the side pressure slide bar, a plurality of rollers are rotatably installed on the side of the correction rod close to the liquid cooling plate, the limit block is installed on the lower pressure plate, and the sliding rack is slidably connected to the limit block.

[0021] The loading assembly includes a second electric telescopic rod, a steering motor is installed on the output shaft of the second electric telescopic rod through a connecting piece, a loading block is installed on the output shaft of the steering motor, and the second electric telescopic rod is installed at the bottom end of the lower pressure plate; the unloading assembly includes a first electric telescopic rod, a unloading block is installed on the output shaft of the first electric telescopic rod, and the first electric telescopic rod is installed at the top end of the lower pressure plate.

[0022] Compared with the prior art, the beneficial effects achieved by the present invention are: the present invention drives the first transmission assembly and the second transmission assembly to drive the transmission through the upper pressure plate at the same time, thereby driving the sliding joint and the correction assembly to operate, realizing automatic correction and full-angle positioning of liquid cooling plates of different sizes, and realizing automatic docking of sealing joints and pressure overload protection. The loading and unloading assemblies are used to realize automatic loading and unloading and continuous detection of liquid cooling plates, saving labor costs.

[0023] By using the positioning marking component, when there is an obvious sealing problem in the liquid cooling plate, the leakage area can be located by detecting the high-temperature leakage gas, and the area can be marked. At the same time, an alarm signal is sent to the staff. The staff finds the corresponding detection area according to the marked point, and by checking the surface of the liquid cooling plate in the area, the leakage point can be quickly found, and then the cause of the leakage can be analyzed. Inflate the liquid cooling plate through the sealing joint, detect the pressure value in the liquid cooling plate within the preset time, and judge the sealing of the liquid cooling plate according to the pressure value.

A plurality of positioning mark components 9 are installed in the side frame 68. A sealing cover 66 is installed on the side frame 68. A vacuum interface 67 is installed on one side of the side frame 68. The vacuum interface 67 is connected to an air pump through a pipeline.

[0043] The gap between the side frame 68, the sealing cover 66 and the positioning mark assembly 9 forms an exhaust chamber, and the exhaust interface 67 is connected to the inside of the exhaust chamber. The air pump extracts the gas in the exhaust chamber from the exhaust interface 67 through the pipeline, so that a negative pressure is formed in the exhaust chamber.

[0044] The positioning mark assembly 9 includes a detection frame 94 and a detection connecting rod 92. A positioning cover 91 is installed on the detection frame 94, and a cone 93 is installed on the positioning cover 91. A detector 95 is installed on the detection frame 94 through the detection connecting rod 92. A detection screw 96 is rotatably installed in the detector 95, and a blade joint 97 is installed on the detection screw 96. A number of temperature-sensing blades 98 are obliquely installed on the blade joint 97. A limit groove 931 is provided in the cone 93.

[0045] Several detection frames 94 divide the surface of the liquid cooling plate into several detection areas. In the normal state, the limit groove 931 in the cone 93 limits the rotation of the temperature sensing blade 98. When the inclined temperature sensing blade 98 rotates under the influence of the airflow, it will be stuck by the limit groove 931 and cannot rotate. The bottom of the detection frame 94 is designed with a bevel surface, which can reduce the contact area with the liquid cooling plate, and the leaking gas is not blocked by the bottom of the detection frame 94.

[0046] The detector 95 includes a detection shell 951, in which a detection screw 96 is rotatably installed. The detection shell 951 is connected to the detection frame 94 through a detection connecting rod 92. A push block 952 is slidably installed in the detection shell 951, and the push block 952 is threadedly connected to the detection screw 96.

A pressure spring 993 is installed between the sensor head 992 and the alarm shell 991, and a piezoelectric element 994 is installed in the alarm shell 991.

[0047] The temperature sensing blade 98 includes a first blade 981 and a second blade 982. The first blade 981 is connected to the second blade 982. The first blade 981 and the second blade 982 are both connected to the blade joint 97. The first blade 981 and the second blade 982 are both made of a material with a large thermal expansion coefficient. The thermal expansion coefficient of the second blade 982 is greater than the thermal expansion coefficient of the first blade 981.

[0048] The first blade 981 and the second blade 982 are pressed together. When the first blade 981 and the second blade 982 are heated, thermal deformation will occur. At this time, the second blade 982 with a high thermal expansion coefficient will bend toward the first blade 981 with a low thermal expansion coefficient. Due to the overall bending deformation of the temperature sensing blade 98, the distance between the temperature sensing blade 98 and the cone 93 increases, so that the temperature sensing blade 98 is separated from the contact with the limiting groove 931, allowing the temperature sensing blade 98 to rotate with the airflow.

[0049] The working principle of the present invention is as follows: the control system controls the transmission device 1 to transport the liquid cooling plate to be inspected to a preset position, and then turns on the second electric telescopic rod 81. The output shaft of the second electric telescopic rod 81 drives the loading block 83 on the steering motor 82 to extend. After the loading block 83 passes through the gap between the transmission devices, the control system turns on the steering motor 82. The output shaft of the steering motor 82 drives the loading block 83 to rotate 90 degrees, so that the loading block 83 abuts against the end of the liquid cooling plate. The output shaft of the second electric telescopic rod 81 is pulled back, so that the loading block 83 drives the liquid cooling plate to slide until the other end of the liquid cooling plate abuts against the lower block 72 in the contracted state. Then the control system turns on the hydraulic device 5, and the hydraulic device 5 drives the sealing detection device 6 to descend.

[0050] When the sealing detection device 6 descends, it drives the upper pressure plate 62 downward, and the upper pressure plate 62 drives the first transmission assembly 64 and the second transmission assembly 65 to slide down. The upper pressure plate 62 drives the transmission screw 645 to descend through the downward pressure spring 642. The transmission screw 645 descends and squeezes the transmission gear 643, so that the transmission gear 643 rotates on the gasket 644. The transmission gear 643 rotates, so that the second transmission assembly 65 drives the sliding rack 611 to slide toward the liquid cooling plate. The sliding rack 611 drives the side pressure slide bar 615 to slide through the side pressure spring 614. The side pressure slide bar 615 drives the correction rod 616 to slide. The correction rods 616 on both sides drive the liquid cooling plate toward The middle offset makes the liquid cooling plate located in the middle position of the lower pressure plate 610, thereby achieving the functions of automatic correction and positioning and meeting the correction and positioning of the liquid cooling plate of the specified size. Afterwards, as the upper pressure plate 62 continues to descend, the correction rod 616 further clamps the liquid cooling plate. When it reaches the critical point, the correction rod 616 stops moving and further moves the sliding rack 611. At this time, since the correction rod 616 and the side pressure slide bar 615 cannot move, the sliding rack 611 drives the side pressure spring 614 to lengthen, preventing the sliding rack 611 from continuing to drive the correction rod 616 to move and causing excessive squeezing on both sides of the liquid cooling plate, thereby achieving the purpose of self-protection. By the same token, the first transmission assembly 64 drives the sliding tooth block 691 to slide toward the liquid cooling plate, so that the sealing joint 693 is docked with the water inlet and outlet of the liquid cooling plate after the deviation correction is completed, and then the upper pressure plate 62 continues to descend. When the sliding tooth block 691 and the sliding rack 611 are unable to move due to the large size of the liquid cooling plate, the lower pressure plate 610 will drive the downward pressure spring 642 to lengthen, so that when the lower pressure plate 610 continues to move downward, it will not drive the first transmission assembly 64 and the second transmission assembly 65 to move downward, so as to prevent the liquid cooling plate from being damaged by excessive squeezing, until the positioning device 63 fits with the surface of the liquid cooling plate, thereby realizing automatic deviation correction and full-angle positioning of liquid cooling plates of different sizes, and realizing automatic docking and pressure overload protection of the sealing joint 693.

[0051] After the sealing joint 693 is connected, the control system controls the air supply device to inflate air into the liquid cooling plate through the sealing joint 693 and controls the inflation speed. Within the preset time, the air pressure inside the liquid cooling plate is converted into an electrical signal and transmitted to the control system through the pressure sensor in the sealing joint 693. The control system determines the sealing performance of the liquid cooling plate by analyzing the electrical signal. When the air pressure reaches the preset value, the surface of the liquid cooling plate is well sealed. When the air pressure obviously does not reach the preset value, the surface of the liquid cooling plate is poorly sealed and there is leakage.

[0052] When there is an obvious sealing problem with the liquid cooling plate, the control system controls the air supply device to continuously fill the liquid cooling plate with high-temperature and high-pressure gas, and at the same time turns on the air pump to form a negative pressure in the vacuum chamber and generate suction. The gas in the detection frame 94 flows into the vacuum chamber and is extracted. At this time, the high-temperature gas that penetrates from the surface of the liquid cooling plate will flow from the detection frame 94 to the cone cylinder 93, and then enter the negative pressure vacuum chamber from the cone cylinder 93. The high-temperature gas passing through the cone cylinder 93 will gradually converge to the top of the cone cylinder 93 and contact the temperature sensing blade 98, causing the temperature sensing blade 98 to heat up. The temperature sensing blade 98 heats up and deforms, and then is driven by the airflow to start rotating. The temperature sensing blade 98 drives the detection screw 96 to rotate, and the rotation of the detection screw 96 drives the propulsion block 952 to rotate. Since the propulsion block 952 is slidingly connected to the detection housing 951 and cannot rotate, the rotation is converted into The shell 951 slides downward, and the push block 952 drives the marking seal 954 to slide down through the positioning link 953. The marking seal 954 drives the alarm to break through the spring door 955. The sensing head 992 on the alarm first slides down and contacts the liquid cooling plate. The sensing head 992 is pressurized and overcomes the elastic force of the pressure spring 993 to slide upward relative to the alarm shell. The sensing head 992 slides upward and squeezes the piezoelectric element 994. The piezoelectric element 994 is pressurized to generate an electrical signal. The control system converts the electrical signal into an alarm signal and sends the alarm signal to the staff. Then the marking seal 954 continues to fall and contacts the surface of the liquid cooling plate. The marking seal 954 marks the surface of the liquid cooling plate. The staff finds the corresponding detection area according to the marked point. By inspecting the surface of the liquid cooling plate in the area, the leakage point can be quickly found, and the cause of the leakage can be analyzed.

[0053] After the inspection is completed, the control system repeats the previous operation in reverse to reset the upper pressure plate 62 and remove the positioning constraint on the liquid cooling plate. The control system turns on the first electric telescopic rod 71. The output shaft of the first electric telescopic rod 71 drives the unloading to extend. The unloading block 72 pushes the inspected liquid cooling plate to the transmission device 1 to complete the unloading. If the inspected liquid cooling plate has a sealing problem, the staff resets the positioning mark assembly 9 corresponding to the leakage area and repeats the above operation to realize automatic loading and unloading inspection of the liquid cooling plate.
