[0045] As mentioned in the background technology, in the related technology, before passing the coolant to the cold plate, an air tightness detection device is required to perform an air tightness detection on the cold plate to avoid coolant leakage. The air tightness detection device includes an air pump, a solenoid valve, an air pressure detector, and connecting pipes. The air pump can pressurize air into the cold plate, and the air pressure change inside the cold plate is measured by the air pressure detector to determine whether there is an air tightness problem.

[0046] However, the existing air tightness detection device can only detect a single cold plate, and the detection efficiency is low.

[0047] In view of the above-mentioned problems existing in the prior art, the present invention provides an air tightness detection device, including a movable support frame, an air pump, a plurality of detection components and a shunt pipe. The air pump is arranged on the movable support frame, and a plurality of detection components are arranged at intervals on the movable support frame. The detection component includes a connector, a pressure detection component, a first connecting pipe, a closing valve and a second connecting pipe connected in sequence, and the connector is used to connect with the component to be detected. The shunt pipe connects each second connecting pipe with the air pump. The airflow output by the air pump can be distributed to each detection component through the shunt pipe, and multiple detection components can perform air tightness detection on multiple cold plates at the same time to improve the detection efficiency. In addition, the closing valve in each detection component can realize the on-off control between each detection channel and the shunt pipe to avoid mutual interference during detection.

[0048] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0049] It is understandable that the airtightness detection device provided in the embodiment of the present application can be used to detect whether the equipment or container has good airtightness, that is, to prevent air, gas or liquid leakage. For example, equipment such as refrigerators, air conditioners, battery packs, servers, etc., can be used to detect whether there is leakage of coolant or other gases. The following is an exemplary explanation using a server as an example, and the part to be detected can be a cold plate used for heat dissipation in the server.

[0050] Reference Figures 1 to 7 As shown, the air tightness detection device provided in the embodiment of the present application includes a movable support frame 100, an air pump 200, a plurality of detection components 300 and a shunt pipe 600.

[0051] The air pump 200 is arranged on the movable support frame 100, and a plurality of detection components 300 are arranged at intervals on the movable support frame 100. The detection components 300 include a connector 310, a pressure detection component 330, a first connection pipe 340, a closing valve 320 and a second connection pipe 350 connected in sequence. The connector 310 is used to connect with the component to be detected. The shunt pipe 600 connects each second connection pipe 350 with the air pump 200.

[0052] When performing an air tightness test on the cold plate in the server, the test component 300 can be connected to the cold plate, and the air pump 200 outputs air pressure to the test component 300 and the cold plate in turn. The air pressure changes inside the cold plate are monitored by the test component 300 to determine whether the air tightness of the cold plate assembly is good.

[0053] The steps for testing the air tightness of the cold plate are as follows:

[0054] Step S11 : the connection head 310 may be connected to the cold plate first, and the closing valve 320 may be opened to connect the first connection pipe 340 to the second connection pipe 350 .

[0055] Step S12: Turn on the air pump 200 and set the injection pressure of the air pump 200. After the air pump 200 injects a predetermined air pressure into the cold plate, observe the air pressure value on the air pump 200 and the air pressure value detected by the pressure detection component 330. After the air pressure value stabilizes, close the closing valve 320 to close the first connecting pipe 340 and the second connecting pipe 350, turn off the air pump 200, and record the initial pressure on the pressure detection component 330.

[0056] Step S13: disconnect the connector 310 from the cold plate, and leave the cold plate alone for a period of time, for example, 1 hour.

[0057] Step S14: Reconnect the connector 310 to the cold plate, record the pressure value on the pressure detection component 330, and compare it with the initial pressure recorded in step S12 to determine whether the air tightness is qualified.

[0058] Before performing air tightness test on the cold plate, the air tightness test on the test assembly 300 itself may be performed first to reduce the error. The test steps are as follows:

[0059] S21 , opening the closing valve 320 to connect the first connecting pipe 340 with the second connecting pipe 350 .

[0060] S22. Turn on the air pump 200 and set the injection pressure of the air pump 200. After the air pump 200 injects a predetermined air pressure into the first connecting tube 340 and the second connecting tube 350, observe the air pressure value on the air pump 200 and the air pressure value detected by the pressure detection component 330. After the air pressure value stabilizes, turn off the air pump 200 and record the initial pressure on the pressure detection component 330.

[0061] S23. After standing for a period of time (e.g., 1 hour), record the pressure value on the pressure detection component 330 and compare it with the initial pressure recorded in step S22 to determine whether the air tightness is qualified. If the air tightness of the detection component 300 itself is unqualified, it needs to be repaired.

[0062] Reference Figures 4 to 6 As shown, the flow divider 600 can distribute the airflow output by the air pump 200 to the second connecting tube 350 of each detection component 300, ensuring that each detection component 300 can obtain the required airflow.

[0063] Thus, multiple detection components 300 can be provided to simultaneously perform air tightness detection on multiple cold plates to improve detection efficiency. In addition, the closing valve 320 in each detection component 300 can realize the on-off control between each detection channel and the shunt pipe 600 to avoid mutual interference during detection.

[0064] Exemplarily, the closing valve 320 may be a solenoid valve in the prior art, and the pressure detecting element 330 may be a pressure gauge in the prior art.

[0065] Reference Figure 2 As shown, the air pump 200 is mainly used to provide air pressure, and the air pump 200 can be a prior art. For example, the air pump 200 can be a small air pump 200, the pressure supply can reach more than 5Kg, and the flow rate is as small as possible. When selecting the air pump 200, it is preferred to select an air pump with a display screen with a human-computer interaction function, which can set any pressure and stabilize the pressure.

[0066] Reference Figure 4 As shown, a socket 380 may be provided on the movable support frame 100 , and the socket 380 is used to connect to an external power source. The closing valve 320 and the pressure detection component 330 in each detection component 300 may be electrically connected to the socket 380 .

[0067] Reference Figure 6 As shown, in some embodiments, an exhaust port 610 is provided on the shunt pipe 600 , and an exhaust valve 620 is provided on the exhaust port 610 .

[0068] In the above embodiment, when the air pressure output by the air pump 200 exceeds the standard, the exhaust port 610 can be opened through the exhaust valve 620 to release the pressure so as to adjust the air pressure inside the detection component 300 .

[0069] Furthermore, when leakage is detected in the detection assembly 300 during the air tightness test of the cold plate, the air pump 200 can be used to supplement the pressure and calibrate the pressure in the detection assembly 300 to the initial pressure of the cold plate through the exhaust valve 620 .

[0091] In the above embodiment, when the air pump 200 is working, the filter element 400 covering the air inlet 102 can block external dust particles outside the installation cavity 101, which can ensure the accuracy of air tightness detection and extend the service life of the air pump 200.

[0092] The filter element 400 is mainly used to filter the air entering the installation cavity 101. Exemplarily, the filter element 400 can be filter cotton, a filter mesh, an activated carbon filter, etc., and the present application does not impose too many restrictions on this.

[0093] Specifically, the filter element 400 may be filter cotton, which is relatively light and low in cost, and can be cut into different shapes and sizes according to the size of the air inlet 102 .
