Description

Technical Field

[0002] The power consumption of the server is getting higher and higher. In the future, air cooling will not be able to meet the cooling needs. Liquid cooling servers are the general trend. The liquid cooling technology of PCIE (Peripheral Component Interconnect Express) cards is still in its infancy. Currently, the liquid cooling plugs on the PCIE card end are divided into two types: hand-inserted and blind-inserted. Among them, the hand-inserted PCIE liquid cooling card is simpler to test for air tightness. The hand-inserted connector has a self-locking function after docking. Therefore, you only need to dock the hand-inserted connector on the detection fixture end with the hand-inserted connector on the PCIE liquid cooling card end to test the air tightness of the PCIE liquid cooling card. However, the blind-inserted PCIE liquid cooling card connector does not have a self-locking function, and there will be a continuous reaction force after the blind-inserted connector is docked. Therefore, there is an urgent need for a fixture that can detect the air tightness of the blind-inserted PCIE liquid cooling card. Summary of the invention

[0055] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0056] It should be noted that the illustrations provided in the following embodiments are only used to illustrate the basic concept of the present invention in a schematic manner, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0057] The detection and processing fixture provided by the present invention is used for post-processing of blind-plug-in liquid-cooled electronic equipment 200. The post-processing described in the present invention includes but is not limited to airtightness detection of blind-plug-in liquid-cooled electronic equipment 200, inert gas protection of blind-plug-in liquid-cooled electronic equipment 200, etc. In fact, the detection and processing fixture provided by the present invention should be applicable to any process that requires inflation or degassing of blind-plug-in liquid-cooled electronic equipment 200.

[0058] The blind plug-in liquid-cooled electronic device 200 of the present invention is provided with a heat dissipation channel, and the two ends of the heat dissipation channel are provided with device-end blind plug connectors; the blind plug-in liquid-cooled electronic device 200 of the present invention can be, for example, a GPU (Graphics Processing Unit) component, especially a GPU component with a PCIE interface. When such electronic devices are used to build a server, multiple GPU components are generally installed on a motherboard, and the GPU components and the motherboard are installed in a chassis. The operating space during installation is very limited, so it is necessary to use a blind plug connector to simplify the assembly process. The blind plug connector of the present invention refers to a connector that can form a sealed passage after docking, and there is no need to set a locking structure such as a nut. The blind plug connector generally includes a male head and a female head that match each other. The male head and the female head are respectively provided with a self-sealing structure, that is, when the male head and the female head are docked, the two are automatically connected, and when the male head and the female head are separated, the two are automatically closed. Since there is no corresponding locking structure between the male head and the female head, the blind plug connector needs to use external force to make the male head and the female head press against each other when in use. To this end, the present invention provides a slot 11 on the base 10 of the detection and processing fixture for guiding the sliding of the blind-plug-in liquid-cooled electronic device 200, and provides a locking mechanism beside the sliding path of the blind-plug-in liquid-cooled electronic device 200. The locking mechanism can press the blind-plug-in liquid-cooled electronic device 200 into the slot 11 after the blind-plug-in liquid-cooled electronic device 200 is docked with the interface on the detection and processing fixture, thereby keeping the blind-plug-in liquid-cooled electronic device 200 connected to the detection and processing fixture, facilitating the subsequent airtightness detection of the blind-plug-in liquid-cooled electronic device 200 or the filling of inert protective gas, simplifying the post-processing process of the blind-plug-in liquid-cooled electronic device 200, and improving work efficiency.

[0059] See also Figure 1-15 As shown, the technical solution of the present invention is described in detail below in conjunction with specific embodiments:

[0060] See also Figure 1-6 As shown, the detection and processing fixture provided by the embodiment of the present invention includes at least one working unit, which is the minimum functional unit that realizes the charging and exhausting functions of a single blind-plug liquid-cooled electronic device 200. In the illustrated embodiment of the present invention, there are two working units. It should be understood that the number of working units can be increased or decreased according to actual needs. For example, in some other embodiments, one, three or more working units can be set.

[0061] See also Figure 1-8 As shown, the working unit includes a base 10, a fixture-end blind plug connector, a first connector 30, a pressure detection unit 60 and a locking mechanism.

[0062] See also Figure 2-5 As shown in FIG. 8 , a slot 11 is provided on the base 10, and the slot 11 is configured to guide the blind-plug-in liquid-cooled electronic device 200 to slide relative to the base 10 along a first direction. It should be noted that the first direction is a relative direction based on the base 10, and the first direction will change synchronously with the change of the posture of the base 10; a flow channel 1000 is provided inside the base 10; in a specific embodiment, the slot 11 can, for example, be distributed at both ends of the base 10, and the slot 11 can be set to a shape that matches the two ends of the length direction of the blind-plug-in liquid-cooled electronic device 200, so as to position the blind-plug-in liquid-cooled electronic device 200; the flow channel 1000 can, for example, be composed of a hole opened in the base 10, or it can be a pipe with an independent pipe wall structure laid in the base 10.

[0063] The fixture-end blind plug connector is connected to the flow channel 1000, and the axial direction of the fixture-end blind plug connector is parallel to the first direction. The fixture-end blind plug connector is used to connect the device-end blind plug connector; in a specific embodiment, one of the fixture-end blind plug connector and the device-end blind plug connector is a male head, and the other is a female head; it should be understood that whether the fixture-end blind plug connector is a male head or a female head is determined by the preset type of the device-end blind plug connector on the blind-plug liquid-cooled electronic device 200. For example, when the device-end blind plug connector is a male head, the fixture-end blind plug connector should be a female head, and when the device-end blind plug connector is a female head, the fixture-end blind plug connector should be a male head.

[0064] The first connector 30 is connected to the flow channel 1000, and the first connector 30 is used to connect an external device; in a specific embodiment, the first connector 30 and the external device do not need to be frequently connected or disconnected, so the first connector 30 can be a hand-plug connector with a built-in locking structure. For example, after the first connector 30 is connected to the pipeline of the external device, a nut or a clamp or other structure can be used to clamp the pipeline of the external device to the first connector 30. The type of external device described in the present invention is determined by the specific post-processing process. For example, when performing air tightness testing on the blind plug-in liquid-cooled electronic device 200, the external device can be an air compressor or a high-pressure gas cylinder; when the blind plug-in liquid-cooled electronic device 200 is protected by inert gas, the external device can be a drying and nitrogen injection device.

[0065] The pressure detection unit 60 is used to detect the pressure of the internal flow channel 1000; in a specific embodiment, the pressure detection unit 60 may be, for example, a pressure gauge, and in some other embodiments, the pressure detection unit 60 may also be other types of pressure sensors.

[0066] The locking mechanism is installed on the base 10, and the locking mechanism is configured to be able to keep the blind-plug-in liquid-cooled electronic device 200 located in the slot 11 in the slot 11, and to make the device-end blind-plug connector press against the fixture-end blind-plug connector. The locking mechanism provided by the present invention can not only limit the displacement of the blind-plug-in liquid-cooled electronic device 200, but also maintain a certain pre-tightening force between the blind-plug connectors to ensure that the blind-plug connectors are reliably sealed.

[0067] It should be noted that the present invention only needs to set one fixture-end blind plug connector to achieve the most advanced function of airtightness detection and filling of inert gas for the blind-plug liquid-cooled electronic device 200, which is as follows: after the blind-plug liquid-cooled electronic device 200 is inserted into the slot 11, one of the device-end blind plug connectors is docked with a fixture-end blind plug connector, and the other device-end blind plug connectors of the blind-plug liquid-cooled electronic device 200 are in a self-sealed state. At this time, the blind-plug liquid-cooled electronic device 200 can be inflated through the first connector 30 to achieve airtightness detection of the blind-plug liquid-cooled electronic device 200; the blind-plug liquid-cooled electronic device 200 can also be first evacuated through the first connector 30, and then the blind-plug liquid-cooled electronic device 200 is filled with inert gas through the first connector 30 to achieve inert gas protection of the blind-plug liquid-cooled electronic device 200.

[0068] See also Figure 1 , 3As shown in Figures 4 and 8, in an optional embodiment of the present invention, the device-end blind plug connector may include, for example, a first device-end blind plug connector 201 and a second device-end blind plug connector 202, and the fixture-end blind plug connector may include, for example, a first fixture-end blind plug connector 21 and a second fixture-end blind plug connector 22, wherein the first fixture-end blind plug connector 21 is used to connect the first device-end blind plug connector 201, and the second fixture-end blind plug connector 22 is used to connect the second device-end blind plug connector 202; the flow channel 1000 includes a first flow channel 1001 and a second flow channel 1002, the first fixture-end blind plug connector 21 and the first connector 30 are connected to the first flow channel 1001, and the second fixture-end blind plug connector 22 and the pressure detection unit 60 are connected to the second flow channel 1002. In this embodiment, two fixture-end blind plug connectors are provided, and the first fixture-end blind plug connector 21 and the second fixture-end blind plug connector 22 can be connected to the first device-end blind plug connector 201 and the second device-end blind plug connector 202 respectively, so that the air tightness and flow performance of the first device-end blind plug connector 201 and the second device-end blind plug connector 202 can be verified at the same time; in addition, since the pressure detection unit 60 is connected to the second flow channel 1002, this area is far away from the first connector 30, and the pressure detection unit 60 will not be disturbed by the air pressure near the first connector 30, and can more accurately reflect the actual pressure inside the blind-plug liquid-cooled electronic device 200, thereby ensuring the reliability of the detection result.

[0069] See also Figure 2-6 As shown, in an optional embodiment of the present invention, the first flow channel 1001 and the second flow channel 1002 are connected through the first pipeline 70, and the first pipeline 70 is provided with a first stop valve 71. When the first stop valve 71 is closed, the first flow channel 1001 and the second flow channel 1002 can only be connected through the heat dissipation channel inside the blind plug-in liquid-cooled electronic device 200, which is convenient for air tightness detection and filling of inert gas for the blind plug-in liquid-cooled electronic device 200; when the first stop valve 71 is opened, the first flow channel 1001 and the second flow channel 1002 can be connected without connecting to the blind plug-in liquid-cooled electronic device 200, which is convenient for checking the air tightness of the detection and processing fixture itself.

[0070] See also Figure 1 , 3 As shown, in an optional embodiment of the present invention, an exhaust valve 90 is further included, and the exhaust valve 90 is installed on the base 10, one end of the exhaust valve 90 is connected to the flow channel 1000, and the other end of the exhaust valve 90 is connected to the atmosphere. The exhaust valve 90 can exhaust and adjust the pressure when the pressure is too high, and on the other hand, it is convenient to empty the working gas in the detection and processing fixture after the use of the detection and processing fixture is over.

[0071] See also Figure 1 , 9-15, in an optional embodiment of the present invention, the locking mechanism includes a locking tongue 40 slidably connected to the base 10, the sliding direction of the locking tongue 40 is perpendicular to or at an angle to the first direction, and an elastic element 50 is provided between the locking tongue 40 and the base 10, and the elastic element 50 is assembled so that its elastic force can drive the locking tongue 40 to protrude from the inner side of the slot 11. In a further specific embodiment, the locking tongue 40 is provided with an inclined surface on the side facing the incoming material when the blind plug-in liquid-cooled electronic device 200 is inserted. When the blind plug-in liquid-cooled electronic device 200 is inserted, the side wall of the blind plug-in liquid-cooled electronic device 200 can push the locking tongue 40 away from the sliding path of the blind plug-in liquid-cooled electronic device 200 through the inclined surface. The blind plug-in liquid-cooled electronic device 200 is provided with a notch 203. When the blind plug-in liquid-cooled electronic device 200 is fully inserted into the slot 11, the locking tongue 40 is aligned with the notch 203. At this time, the locking tongue 40 is inserted into the notch 203 under the action of the elastic element 50, so as to achieve the locking of the blind plug-in liquid-cooled electronic device 200. In a specific embodiment, the elastic element 50 can be, for example, a compression spring, and the locking tongue 40 can be provided with a positioning hole 42 for positioning the compression spring, so as to facilitate the assembly of the locking tongue 40 and the compression spring with the base 10 to prevent the compression spring from being skewed.

[0072] See also Figure 2 , 3 , 4, 6, 10, 12, and 14, in an optional embodiment of the present invention, a handle 41 is provided at one end of the lock tongue 40 away from the slot 11. The handle 41 facilitates the operator to release the constraint of the locking mechanism on the blind plug-in liquid-cooled electronic device 200. Specifically, the operator can pull the lock tongue 40 out of the notch 203 of the blind plug-in liquid-cooled electronic device 200 through the handle 41. At this time, the blind plug-in liquid-cooled electronic device 200 can bounce upward under the reaction force of the blind plug connector, which is convenient for the operator to take the blind plug-in liquid-cooled electronic device 200 out of the slot 11.

[0073] See also Figure 1-4 As shown in FIGS. 9, 11 and 13, in an optional embodiment of the present invention, a buffer pad 12 made of elastic material is provided at the bottom of the slot 11. The buffer pad 12 can prevent the bottom of the blind plug-in liquid-cooled electronic device 200 from colliding with the base 10 during the insertion of the blind plug-in liquid-cooled electronic device 200, thereby preventing the blind plug-in liquid-cooled electronic device 200 from being damaged.

[0074] See also Figure 1-6As shown, in an optional embodiment of the present invention, the working unit is provided with at least two, and the first flow channels 1001 of at least two of the working units are connected through a second pipeline 80, and a second stop valve 81 is provided on the second pipeline 80. When the second stop valve 81 is opened, the flow channels 1000 of each working unit are connected to each other. At this time, all working units can be inflated or evacuated at the same time through the first interface of a working unit, thereby improving work efficiency; when the second stop valve 81 is closed, the flow channels 1000 of each working unit are isolated from each other, and at this time, the independence of the detection results of each pressure detection unit 60 can be guaranteed, so as to facilitate the accurate acquisition of the air pressure of each blind plug-in liquid-cooled electronic device 200.

[0075] See also Figure 1-6 As shown, in an optional embodiment of the present invention, the bases 10 of the working units are interconnected by a crossbeam 100, and at least one of the crossbeams 100 is provided with a handle for a person to hold, so as to facilitate the movement of the inspection and processing fixture.

[0076] The detection and processing jig provided by the present invention can have different uses in different processes, which are described below in conjunction with several specific embodiments:

[0077] Example 1

[0078] Based on the above detection and processing fixture, the present invention provides an airtightness detection method, which is used to perform airtightness detection on a blind plug-in liquid-cooled electronic device 200, comprising the following steps:

[0079] Providing the detection and processing jig;

[0080] Inserting the blind-plug-in liquid-cooled electronic device 200 to be tested into the slot 11 until the locking mechanism holds the blind-plug-in liquid-cooled electronic device 200 in the slot 11;

[0081] Open the second stop valve 81 and close the first stop valve 71, connect the first connector 30 of at least one of the working units to the high-pressure gas source, and inflate the flow channel 1000 of each of the working units until the detection value of the pressure detection unit 60 reaches a first preset value;

[0082] The second stop valve 81 is closed, and the locking mechanism is released from the blind-plug-in liquid-cooled electronic device 200 , and the blind-plug-in liquid-cooled electronic device 200 is removed from the slot 11 ;

[0083] After waiting for a first preset time, reinsert the blind-plug-in liquid-cooled electronic device 200 into the slot 11 until the locking mechanism holds the blind-plug-in liquid-cooled electronic device 200 in the slot 11;

[0085] The present invention connects the flow channels 1000 of multiple working units through the second pipeline 80, and can simultaneously perform detection of other working units while one working unit is inflated or exhausted, thereby significantly improving the detection efficiency; after the detection is completed, the constraint of the locking mechanism is released, and the blind plug-in liquid-cooled electronic device 200 can be quickly removed, simplifying the operation process and reducing the operation time; through independent detection of multiple working units, the pressure detection unit 60 of each working unit can independently read the air pressure value, ensuring the independence and accuracy of the air tightness detection result of each blind plug-in liquid-cooled electronic device 200, and after reinserting the blind plug-in liquid-cooled electronic device 200, the detection value of the pressure detection unit 60 is read again, and by comparing the detection values ​​before and after the two times, it can be more accurately determined whether the air tightness of the blind plug-in liquid-cooled electronic device 200 meets the requirements; by setting multiple working units, the number of working units can be increased or decreased according to actual needs, adapting to different production scales and detection requirements; the setting of the first stop valve 71 and the second stop valve 81 enables the detection and processing fixture to be flexibly switched in different detection modes, and can perform independent detection on a single working unit or synchronous detection on multiple working units.

[0087] Based on the above-mentioned detection and processing fixture, the present invention also provides an airtightness detection method, which is used to verify the airtightness of the detection and processing fixture itself, and includes the following steps:

[0088] Providing the detection and processing jig for the blind plug-in liquid-cooled electronic device 200 that is not installed;

[0089] Open the first stop valve 71 and the second stop valve 81, connect the first connector 30 of at least one of the working units to the high-pressure gas source, and inflate the flow channel 1000 of each of the working units until the detection value of the pressure detection unit 60 reaches a second preset value;

[0090] After waiting for a second preset time, read the second current detection value of the pressure detection unit 60, and compare the second current detection value with the second preset value. If the second difference between the second current detection value and the second preset value is less than the second preset difference, the detection and processing fixture meets the airtightness requirements.

[0091] The present invention performs airtightness verification on the detection and processing fixture when the blind-plug liquid-cooled electronic device 200 is not installed, which can ensure that the detection and processing fixture itself has no leakage problems, which is crucial for the subsequent airtightness detection of the blind-plug liquid-cooled electronic device 200; by connecting all working units of the detection and processing fixture and inflating all flow channels 1000 at the same time, the airtightness of all working units can be tested at one time. This global detection method can more comprehensively check various parts of the detection and processing fixture to ensure that no potential leakage points are missed.

[0092] Example 3

[0093] Based on the above detection and processing fixture, the present invention also provides a protection method for a blind plug-in liquid-cooled electronic device 200, comprising the following steps:

[0094] Providing the detection and processing jig;

[0095] Inserting the blind-plug-in liquid-cooled electronic device 200 into the slot 11 until the locking mechanism holds the blind-plug-in liquid-cooled electronic device 200 in the slot 11;

[0096] Open the second stop valve 81 and close the first stop valve 71, connect the first connector 30 of at least one of the working units with the negative pressure device, and evacuate the flow channel 1000 of each of the working units until the detection value of the pressure detection unit 60 is less than the third preset value;

[0097] Connecting the first connector 30 of at least one of the working units to an inert gas source, and filling the flow channel 1000 of each of the working units with inert gas until the detection value of the pressure detection unit 60 is greater than a fourth preset value;

[0098] The locking mechanism is released from the constraint on the blind-plug-in liquid-cooled electronic device 200 , and the blind-plug-in liquid-cooled electronic device 200 is removed from the slot 11 .

[0099] The present invention can completely remove the air and moisture inside the blind plug-in liquid cooling electronic device 200 through the steps of vacuuming and filling with inert gas, ensuring that the device will not be damaged by moisture or other corrosive gases during subsequent use. This is especially important for high-precision and high-reliability electronic devices (such as GPU components); the filling of inert gas can provide a stable protective environment to prevent the device from being affected by the environment during long-term storage or transportation, ensuring the long-term reliability of the device.

[0100] In summary, the present invention provides a slot for guiding the sliding of the blind-plug-in liquid-cooled electronic device on the base of the detection and processing fixture, and provides a locking mechanism beside the sliding path of the blind-plug-in liquid-cooled electronic device. The locking mechanism can press the blind-plug-in liquid-cooled electronic device into the slot after the blind-plug-in liquid-cooled electronic device is docked with the interface on the detection and processing fixture, thereby keeping the blind-plug-in liquid-cooled electronic device and the detection and processing fixture in a connected state, facilitating the subsequent air-tightness detection of the blind-plug-in liquid-cooled electronic device or the filling of inert protective gas, simplifying the post-processing process of the blind-plug-in liquid-cooled electronic device, and improving work efficiency.
