Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a radiator sealing testing device and a radiator production and processing system. Background Technology

[0002] In electronic devices, new energy battery systems, and industrial cooling devices, the sealing performance of radiators is a key indicator for ensuring efficient operation and preventing media leakage. Currently, the industry commonly uses the water immersion bubble detection method to test the sealing of radiator products. This involves filling the radiator with gas at a certain pressure, completely immersing it in water, and observing whether bubbles appear on the water surface to determine if there is a leak.

[0003] However, this traditional testing method has significant drawbacks. For products with minor leaks or slow leaks, the amount of gas escaping per unit time is extremely small, and the resulting bubbles are weak and easily dispersed, making them difficult to capture with conventional water bubble testing. This leads to a serious lack of accuracy in the test results, resulting in a large number of missed detections and misjudgments. Consequently, radiators with sealing defects enter the market, potentially causing equipment failures, liquid leaks, or even safety accidents. In addition, the radiators need to be dried after immersion testing, which increases the complexity of the process and time costs, and reduces production efficiency.

[0004] With the advancement of industrial automation and the continuous improvement of product quality requirements, the traditional water immersion bubble detection method can no longer meet the modern manufacturing industry's demand for high efficiency, accuracy and intelligence in radiator sealing inspection. There is an urgent need for a new sealing inspection technology with a high degree of automation and reliable detection accuracy. Summary of the Invention

The partition is connected to the inner wall of the protective cover, and the accommodating space is divided into multiple independent spaces.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0026] Example 1:

[0027] See Figure 1 and Figure 2 As shown, this embodiment provides a radiator sealing test device, which includes: a machine base 100, the top of which is provided with a bearing surface 130; a fixing mechanism 200, which is connected to the bearing surface 130 and includes a product connecting plate 220, on which the radiator product to be tested is fixed; and a test mechanism 300, which includes a sealing air guide assembly 330, a pressure holding air inlet connector 310, a sealing connector 320, and a leak detector 340. The leak detector 340 is installed inside the machine base 100. It is connected to an external air supply device and is connected to the pressure-holding air inlet connector 310 through the sealing air guide assembly 330. The pressure-holding air inlet connector 310 includes a first connector body 311 and an air supply nozzle 312 that are connected to each other. The air supply nozzle 312 can be connected to the air inlet end of the heat sink to be tested. The sealing connector 320 includes a second connector body 321 and a sealing nozzle 322 that are connected to each other. The sealing nozzle 322 can seal the air outlet end of the heat sink to be tested.

[0028] The radiator sealing test equipment described in this embodiment uses a fixing mechanism 200 to fix the radiator to be tested, and then a testing mechanism 300 to perform an inflation and pressure holding test on the radiator. During the test, the pressure holding air inlet connector 310 can supply air to the radiator to be tested through an external air supply device, and the air supply end is sealed by the sealing air guide component 330. The sealing connector 320 can seal the exhaust end of the radiator, thereby maintaining the isolation between the internal and external environments of the radiator. On this basis, the leak detector 340 can achieve high-precision detection of the radiator sealing performance by real-time monitoring of the internal gas pressure of the radiator. Compared with the conventional bubble detection methods in the industry at present, this application has the advantages of high detection accuracy, wide applicability, high detection efficiency, and strong compatibility.

[0029] In this embodiment, the machine base 100 provides an installation and connection platform for other structures. It is preferably a rectangular box. The machine base 100 includes a protective cover 110, a partition 120, and a door panel 140. The protective cover 110 is disposed below the bearing surface 130 and, together with the door panel 140, encloses an accommodating space. The partition 120 is connected to the inner wall of the protective cover 110, and the accommodating space is divided into multiple independent spaces. The leak detector 340 is installed in one of these independent spaces and is connected to the sealing and air guiding assembly 330 via a connecting pipe. The partition 120 is horizontally disposed inside the machine base 100 to divide the interior of the machine base 100 into two independent spaces for installing the leak detector 340 and other auxiliary structures, thereby improving the layout rationality of the structure in this application.

[0030] See Figure 2As shown, the fixing mechanism 200 in this embodiment is used to connect the heat sink to be tested. The fixing mechanism 200 achieves accurate positioning and reliable fixing of the heat sink product to be tested through the synergistic action of the baffle 240 and the clamping assembly 250, ensuring that the product remains stationary during the test and avoiding sealing failure or detection error caused by shaking. It includes a baffle 240 arranged around the edge of the product connecting plate 220 and at least one clamping assembly 250. The baffle 240 is fixedly connected to the product connecting plate 220. One of the clamping assemblies 250 includes a drive cylinder 251 and a clamping plate 252. The drive cylinder 251 is connected to the product connecting plate 220, and the clamping plate 252 is connected to the working end of the drive cylinder 251 to move relatively closer to / away from the heat sink product to be tested. The flange 240 can be fixedly connected to the edge of the connecting plate 220 around the product to form a closed or semi-closed frame structure. For multi-model heat sink testing scenarios, flanges 240 of different specifications can be replaced modularly to adapt to different product sizes and improve the versatility of the fixture. The drive cylinder 251 serves as the power source for the clamping assembly 250. It drives the piston rod to make linear reciprocating motion through compressed air to provide controllable clamping force for the clamping plate 252. The shape design of the clamping plate 252 needs to match the force-bearing surface of the heat sink to ensure that the clamping force is evenly distributed and to prevent local stress concentration from causing product deformation or sealing failure.

[0031] Specifically, the fixing mechanism 200 further includes a support plate 210, one end of which is vertically connected to the bearing surface 130, and the other end extends along the thickness direction of the connecting plate and connects to the product connecting plate 220. The bearing surface 130, the support plate 210, and the product connecting plate 220 together enclose an installation space, and the driving cylinder 251 is disposed in the installation space, thereby further improving the rationality of the structural layout of this application.

[0032] Furthermore, in this embodiment, the product connecting plate 220 is provided with four positioning blocks 230. The positioning blocks 230 are protruding from the product connecting plate 220 toward the heat sink to be tested, so as to pass through the corresponding structure of the heat sink product, thereby further improving the relative stability between them and the product connecting plate 220.

[0033] See Figures 3 to 5As shown, the sealing and air guiding assembly in this embodiment includes a connecting pipe 335 and a sealing plate 336. The connecting pipe 335 is provided with an air inlet 333 and an air outlet 337. The air inlet 333 is connected to the leak detector 340, and the air outlet 337 is located at the end of the connecting pipe 335 facing the heat sink to be tested, and is inserted into the first connector body 311. The sealing plate 336 is arranged around the air outlet 337 to seal and stop the connection between the air outlet 337 and the first connector body 311. During the test, the leak detector 340 can be connected in series between the air supply device and the sealing and air guiding assembly 330 to supply air to the heat sink through the pressure-holding air inlet connector 310. At the same time, the sealing connector 320 can seal the air outlet of the heat sink to achieve isolation between the internal and external environments of the heat sink.

[0034] Furthermore, the sealing air guide assembly 330 also includes a mounting bracket 331, a horizontal actuator 332, and a fixing plate 334. The mounting bracket 331 is connected to the fixing mechanism 200, the horizontal actuator 332 is mounted on the mounting bracket 331, one side of the fixing plate 334 is connected to the working end of the horizontal actuator 332, and the other side is connected to the connecting pipe 335, so as to drive the connecting pipe 335 to move towards / away from the pressure-holding air inlet connector 310. The mounting bracket 331, as a basic support structure, can prevent the mounting bracket 331 from shaking due to the reaction force of the horizontal actuator 332, thereby avoiding affecting the docking accuracy between the connecting pipe 335 and the pressure-holding air inlet connector 310. The horizontal actuator 332 is preferably a linear cylinder, which can realize the horizontal reciprocating motion of the fixing plate 334. The fixing plate 334 forms a power transmission chain to ensure that the connecting pipe 335 moves synchronously with the fixing plate 334.

[0035] Furthermore, the radiator sealing test equipment also includes a pressure boosting valve 350 and a control mechanism. The pressure boosting valve 350 is located inside the machine base 100 and is positioned between the leak detector 340 and the external air supply equipment. The fixing mechanism 200, the test mechanism 300, and the leak detector 340 are respectively connected to the control mechanism. In actual production and processing, operators can adjust the above structure in real time through the control mechanism, thereby improving the flexibility of the equipment. Parameters can also be preset through the control mechanism, thereby improving the automation level of the equipment.

[0036] The testing process of the radiator sealing test equipment in this embodiment is described below:

[0037] During installation, the air supply equipment needs to be connected to the air inlet 333 of the sealing air guide assembly 330 through a connecting pipe. At the same time, the leak detector 340 is connected in series in the connecting pipe. Then, the sealing air guide assembly 330 is driven to mate with the first connector body 311 of the pressure-holding air inlet connector 310. Next, air is supplied to the radiator through the air supply nozzle 312 of the pressure-holding air inlet connector 310. At the same time, the exhaust end of the radiator is sealed through the sealing nozzle 322 of the sealing connector 320. The radiator is then kept in a static state for a preset time. During the static state, the leak detector 340 monitors the changes in internal air pressure of the radiator in real time to determine the internal sealing condition of the radiator.

[0038] Example 2:

[0039] This embodiment provides a radiator manufacturing and processing system, which includes the radiator sealing test equipment described above.

[0040] In summary, the radiator sealing test equipment and radiator manufacturing system described in this utility model fix the radiator to be tested using the fixing mechanism 200, and then perform a pressure test on the radiator using the testing mechanism 300. During the test, the pressure-holding air inlet connector 310 supplies air to the radiator to be tested through an external air supply device, and the air supply end is sealed by the sealing air guide component 330. The sealing connector 320 seals the exhaust end of the radiator, thereby maintaining the isolation between the internal and external environments of the radiator. Based on this, the leak detector 340 can achieve high-precision testing of the radiator's sealing performance by real-time monitoring of the internal gas pressure of the radiator. Compared with the conventional bubble detection methods currently used in the industry, this application has the advantages of high detection accuracy, wide applicability, high detection efficiency, and strong compatibility, and has broad application prospects in the industry.

[0041] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
