Description

Technical Field

[0001] The invention relates to the technical field of alternative composite plate detection, in particular to a method for detecting cold plate false welds, leaky welds and internal blockages by utilizing X-rays. Background Art

[0002] A heat pipe heat exchanger is a composite device of a heat pipe and a heat exchanger. It needs to undergo performance testing before leaving the factory. Furthermore, after a period of use, the heat pipe heat exchanger may experience leakage, breakage, or damage to the vacuum environment. Damage to the vacuum environment increases the amount of non-condensable gas inside, reducing the thermal conductivity. Damage to the vacuum environment inside the heat pipe is difficult to detect. Usually, this problem can only be discovered by removing and disassembling the heat exchanger to inspect the interior. However, heat pipe heat exchangers are used in large quantities, and disassembling them for inspection is extremely inefficient. Summary of the Invention

[0003] The purpose of the present invention is to provide a method for detecting cold plate false solder joints, leaking solder joints and internal blockages by using X-rays, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above object, the present invention provides the following technical solution: a method for detecting cold plate false welds, leaking welds, and internal blockages using X-rays, comprising the following steps:

[0005] Step 1: Ensure all equipment has been calibrated and is in good working condition, and operators must wear appropriate protective equipment;

[0006] Step 2: Select appropriate X-ray machine parameters according to the material and thickness of the inspection object, and adjust the distance between the X-ray machine's focus and the inspection object;

[0007] Step 3: Turn on the X-ray machine to preheat and start exposure. The X-ray machine will emit X-rays to penetrate the inspection object;

[0008] Step 4: After the test is completed, the X-ray images obtained are manually analyzed in detail;

[0009] Step 5: After completing the inspection, turn off the X-ray machine and perform necessary equipment maintenance.

[0010] Further optimization is that in step 1, the operator needs to wear appropriate protective equipment, such as a lead apron and protective glasses, to reduce radiation exposure. At the same time, the test product is fixed on the test table to ensure accurate test results.

[0011] Further optimized, in step 2, the X-ray machine parameters include tube voltage, current and exposure time.

[0012] For further optimization, in step 2, the relative position of the focus and the detection object is ensured to be correct, and an image intensifier or detector is set to obtain a clear image.

[0013] Further optimization is made in step three, where the detection equipment is manually monitored during the exposure process to ensure a safe and smooth detection process.

[0014] Further optimized, in step 4, abnormal shadows or structures in the image are analyzed, and abnormal shadows or structures are indicators of internal defects or irregularities, and are judged by comparing with standard images or previous detection results.

[0015] Beneficial effects

[0016] The method provided by the present invention uses X-rays to detect cold plate false solder joints, leaking solder joints, and internal blockages. The product is inspected by X-rays, and the inspection efficiency is high. Quality control can be guaranteed to a certain extent. The manual operation is convenient, which improves the production yield of the enterprise and reduces the production cost of the enterprise. DETAILED DESCRIPTION

[0017] The following are specific embodiments of the present invention, which further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0018] Example

[0019] A method for detecting cold plate false solder joints, leaky solder joints, and internal blockages using X-rays, comprising the following steps:

[0023] Step 4: After the test is completed, the X-ray images obtained are manually analyzed in detail;

[0024] Step 5: After completing the inspection, turn off the X-ray machine and perform necessary equipment maintenance.

[0025] In this embodiment, in step 1, the operator needs to wear appropriate protective equipment, such as a lead apron and protective glasses, to reduce radiation exposure. At the same time, the test product is fixed on the test table to ensure accurate test results.

[0026] In the step 2, the X-ray machine parameters include tube voltage, current and exposure time.

[0027] In the second step, ensure that the relative position of the focus and the detection object is correct, set the image intensifier or detector, and obtain a clear image.
