[0002] In the processing of thin -walled radiating pipe, sealing detection is the key link to ensure product quality. The traditional radiating pipe sealing detection technology has many defects, and it is difficult to meet the efficient, high-precision demand of modern industrial production.

[0003] In the past detection means, often lack accurate pressure monitoring equipment. For example, some simple detection method only through naked eye observation whether there is bubble to judge the sealing, this mode is extremely dependent on the experience and concentration of operating personnel, and the subjectivity is strong and the error is great, cannot accurately detect the tiny leakage, leads a large number of poor sealing radiating pipe to flow into subsequent process or market, seriously influence the overall performance and service life of product.

[0004] At the same time, the traditional detection equipment performs poorly in sealing performance. Because the radiating pipe is special in shape and thin in wall, the conventional sealing mode is difficult to closely adhere to its surface, which easily causes gas leakage, making the air pressure unstable in the detection process, thereby interfering with the accuracy of the detection result. Moreover, the imperfect sealing structure also leads to frequent leakage misjudgment or missed detection during the detection process, requiring multiple repeated detection, which greatly reduces the detection efficiency.

For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0025] The utility model will be further described in detail in combination with examples as follows:

[0026] Example 1

[0027] As Figures 1-4 Indicated, the utility model provides a kind of sealing detection equipment for thin-walled radiating pipe processing, including detection platform 1, touch screen controller 2, mounting bracket 3 and pressure sensor 14, the upper surface of detection platform 1 is fixedly connected with the sealing bottom frame 6 for receiving thin-walled radiating pipe, the upper portion of sealing bottom frame 6 is provided with the sealing cover 5 for butt joint sealing with it;

[0028] The top center of sealing cover 5 is fixedly connected with air cylinder 4, the outer wall of sealing cover 5 is fixedly connected with air supply pipe 7, and the end of air supply pipe 7 away from sealing cover 5 is provided with air supply assembly.

[0029] The bottom of sealing cover 5 is fixedly connected with upper sealing block 11, the upper surface of sealing bottom frame 6 is fixedly connected with lower sealing block 12 matched with upper sealing block 11, and the side of upper sealing block 11 and lower sealing block 12 close to each other is provided with arc groove.

[0030] The air supply assembly is used to inflate the sealed space formed after the sealing cover 5 and the sealing bottom frame 6 are connected, so as to increase the internal air pressure to the preset value.

[0031] The air supply assembly includes an air compressor 8, the outlet of which is fixedly connected to one end of an air supply pipe 7. A pressure regulating valve 15 is fixedly connected to the outer wall of the air supply pipe 7. The air compressor 8 is electrically connected to the touch screen controller 2.

[0032] Example 2

[0033] like Figures 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a sealing receiving groove 10 is provided on the upper surface of the sealing bottom frame 6, and a sealing insert plate 9 is provided on the bottom surface of the sealing cover 5, with the bottom end of the sealing insert plate 9 inserted into the inner wall of the sealing receiving groove 10.

[0034] Both the upper sealing block 11 and the lower sealing block 12 have rubber sealing layers 13 fixedly connected to their outer walls.

[0035] The outer wall of cylinder 4 is fixedly connected to one end of mounting bracket 3, and pressure sensor 14 is fixedly connected to the top of the inner wall of sealing cover 5.

[0036] The working principle of the sealing test equipment used for processing thin-walled heat pipes will be explained in detail below.

[0037] like Figures 1-4 As shown, when in use, place both ends of the thin-walled heat dissipation tube to be tested into the two sets of lower sealing blocks 12 on the sealing base frame 6, and adjust their positions so that the lengths of the protrusions at both ends are the same.

[0038] Then, the cylinder 4 is activated via the touchscreen controller 2, causing it to slowly lower the sealing cover 5 until the upper sealing block 11 aligns with the lower sealing block 12. At this point, the sealing cover 5 and the sealing base frame 6 form a sealed space. Afterward, the air compressor 8 is activated again via the touchscreen controller 2, delivering air to the sealing cover 5. The pressure regulating valve 15 then adjusts the air pressure to the set detection pressure value, for example, 0.5 - 1.5 MPa (which can be adjusted according to the specific requirements of the heat dissipation pipe).

[0039] Pressure sensor 14 monitors the air pressure change inside the sealing cover in real time. Within a specified detection time, such as 30-60 seconds, if the air pressure drop is within the allowable error range (such as less than 5% of the set pressure), the heat sink is judged to be in good sealing condition. If the air pressure drop exceeds the allowable value, the heat sink is judged to be leaking. The touch screen controller 2 issues an alarm signal and displays the leak information and related data on the display screen.

[0040] After the test is completed, the sealing cover 5 is raised, the tested heat pipe is removed, and the next heat pipe is ready for testing.

[0041] It should be noted that, in this text, the term "comprising" "including" or any other variant is intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. Without more limitations, the element defined by the statement "including a" does not exclude the presence of other identical elements in the process, method, article or device including the element. The above generally describes the present application in detail, but some modifications or improvements can be made on the basis of the present application, which is obvious to those skilled in the art. Therefore, the modifications or improvements without departing from the spirit of the present application are within the scope of protection of the present application.
