Description

Technical Field

[0001] This utility model relates to a helium detection device, and more particularly to a helium detection device for a harmonica tube water-cooled plate. Background Technology

[0002] Water-cooled plates undergo performance and quality testing before leaving the factory, such as using helium detectors to test their airtightness. Existing conventional helium detectors consist of a gas source, pressure reducing valve, gas source switch, station filter, vacuum chamber, and helium detector, connected sequentially by piping. Before testing, the water-cooled plate is placed in the vacuum chamber, and the piping is connected to it. Once the testing process begins, helium is introduced from the gas source, pressure reduced by the pressure reducing valve, and then the gas source switch is opened, allowing the gas to flow to the station filter. After filtration, the gas flows to the water-cooled plate, and the helium detector measures the leakage rate within the vacuum chamber. However, after prolonged use, the sealing door and the vacuum chamber itself are prone to wear, leading to a deterioration in the sealing effect and potential leakage. This can cause inaccuracies in the water-cooled plate airtightness test results, reducing the overall accuracy of the test. Utility Model Content

[0003] The purpose of this utility model is to provide a harmonica tube water-cooled plate helium detection device to solve the problem that after long-term use, the sealing door and vacuum chamber are easily worn, resulting in poor sealing effect and leakage, which leads to deviation in the airtightness test of the water-cooled plate and reduces the accuracy of the test results.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a harmonica tube water-cooled plate helium detection device, comprising: a vacuum chamber, a helium tank, a vacuum pump, and a helium detector. The vacuum chamber is connected to the vacuum pump via a first pipe, the helium tank is connected to the water-cooled plate inside the vacuum chamber via a second pipe, and the helium detector is connected to the vacuum chamber via a third pipe.

[0005] The vacuum chamber includes a chamber body and a sealing door. The chamber body is provided with a sealing groove. The sealing door is movably connected to the chamber body. A protrusion is provided on one side of the sealing door. The protrusion is inserted into the sealing groove. An inflation hose is provided on the protrusion. An inflation tube is provided on the inflation hose. The inflation tube passes through the sealing door and is connected to an air source.

[0006] As a further description of the above technical solution:

[0007] A cylinder is installed inside the box, and a sealing rod is installed on the cylinder. The sealing rod is a hollow rod. One end of the sealing rod is connected to the second pipe, and the other end of the sealing rod is connected to the water-cooling plate.

[0008] As a further description of the above technical solution:

[0009] The sealing door is hinged to the housing.

[0010] As a further description of the above technical solution:

[0011] The protrusion is a rectangular or circular frame structure.

[0012] As a further description of the above technical solution:

[0013] The sealed door is equipped with a transparent observation window.

[0014] As a further description of the above technical solution:

[0015] The transparent observation window is a glass window.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: by setting a protrusion and an inflation hose on the sealing door, after the sealing door is closed, the protrusion is inserted into the sealing groove, and air is supplied to the inflation hose through the inflation pipe, causing the inflation hose to inflate and expand. After the inflation hose arranged along the outer periphery of the protrusion expands, it contacts the inner wall of the sealing groove, so that there is no gap between the protrusion and the inner wall of the sealing groove, which improves the sealing effect, prevents external air from entering the chamber, and improves the accuracy of the test results.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-3 This utility model provides a technical solution: a helium detection device for a harmonica tube water-cooled plate, comprising: a vacuum chamber 1, a helium tank 2, a vacuum pump 3, and a helium detector 4. The vacuum chamber 1 is connected to the vacuum pump 3 via a first pipe 5. The helium tank 2 is connected to the water-cooled plate inside the vacuum chamber 1 via a second pipe 6. The helium detector 4 is connected to the vacuum chamber 1 via a third pipe 7.

[0025] The vacuum chamber 1 includes a chamber body 11 and a sealing door 12. The chamber body 11 is provided with a sealing groove 8. The sealing door 12 is movably connected to the chamber body 11. A protrusion 9 is provided on one side of the sealing door 12. The protrusion 9 is inserted into the sealing groove 8. An inflation hose 10 is provided on the protrusion 9. An inflation tube 13 is provided on the inflation hose 10. The inflation tube 13 passes through the sealing door 12 and is connected to an air source.

[0026] A cylinder 14 is installed inside the housing 11, and a sealing rod 15 is installed on the cylinder 14. The sealing rod 15 is a hollow rod, one end of which is connected to the second pipe 6, and the other end of which is connected to the water-cooled plate. During operation, different cylinders drive the sealing rod to insert into the liquid inlet and outlet of the water-cooled plate to seal it.

[0027] The sealing door 12 is hinged to the housing 11.

[0028] The protrusion 9 is a rectangular or circular frame structure. The shape of the protrusion is adapted to the shape of the inlet and outlet of the box.

[0029] The sealed door 12 is equipped with a transparent observation window 16. The transparent observation window 16 is a glass window, which allows for easy observation of the situation inside the enclosure.

[0030] Working Principle: A water-cooled plate is placed inside the chamber. A vacuum chamber is evacuated. Then, different cylinders drive a sealing rod to insert into the liquid inlet and outlet of the water-cooled plate, sealing it. Helium is then injected into the water-cooled plate through a helium tank via a second pipe and the sealing rod. If there is a leak in the water-cooled plate, helium will flow into the vacuum chamber, which will be detected by the helium detector, triggering an alarm. Therefore, this invention, by providing a protrusion and an inflation hose on the sealing door, allows the protrusion to insert into the sealing groove after the door is closed. Inflation is supplied to the inflation hose through the inflation pipe, causing the hose to expand. The expanded hose, arranged along the outer periphery of the protrusion, contacts the inner wall of the sealing groove, eliminating any gap between the protrusion and the inner wall of the sealing groove. This improves the sealing effect, prevents external air from entering the chamber, and enhances the accuracy of the test results.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
