Description

Technical Field

[0001] This utility model relates to the technical field of liquid-cooled plate testing equipment, specifically to an airtightness testing device for aluminum extruded liquid-cooled plate housings. Background Technology

[0002] Liquid-cooled plate housings typically use materials with high thermal conductivity, such as aluminum alloys, copper, or aluminum-based composite materials, to ensure that the battery can effectively dissipate heat in high-temperature environments, maintaining performance and safety. The aluminum extrusion liquid-cooled plate housing airtightness detection device is used to detect whether there are gaps or leaks in the rivet holes and inner cavity on the liquid-cooled plate beams.

[0003] However, existing testing equipment lacks intuitive visualization when testing the airtightness of rivet holes and inner cavities of liquid-cooled plate beams, which reduces the convenience and efficiency of the equipment in testing the airtightness of rivet holes and inner cavities of liquid-cooled plate beams. Therefore, there is an urgent need for an airtightness testing device for aluminum extruded liquid-cooled plate boxes to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide an airtightness testing device for aluminum extruded liquid-cooled plate housings, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an airtightness testing device for an aluminum extruded liquid-cooled plate housing, comprising an air guiding device for support, aluminum profile columns at the four corners of the lower end face of the air guiding device, ten sets of connecting air pipes evenly spaced on the lower end face of the air guiding device, and a testing water tank located at the side end of the ten sets of connecting air pipes.

[0006] A visual inspection water tank is provided, wherein the visual inspection water tank is equidistantly disposed on the upper end surface of the inspection water tank, and the visual inspection water tank is used to inspect air tightness.

[0007] A rotary pressing cylinder is fixedly arranged at equal intervals on the upper end face of the air guiding device, and a liquid cooling plate box is fixedly clamped to the upper end face of the air guiding device through the rotary pressing cylinder. A liquid cooling plate cavity is opened in the middle of the inner end face of the liquid cooling plate box, and rivet holes are opened at equal intervals on the side of the lower end face of the liquid cooling plate box.

[0008] The threaded baffle has four sets, and all four sets of threaded baffles are threadedly connected to the inner end face of the air guiding device. The threaded baffles are used to limit the side of the liquid cooling plate box.

[0009] Preferably, the air guiding device includes a support guide seat, four sets of threaded guide shafts are equidistantly and rotatably engaged on the inner end face of the support guide seat, and a rubber sealing ring is provided on the upper end face of the support guide seat near the outside. Detection air holes are equidistantly opened on the upper end face of the rubber sealing ring near the side. Three sets of air guiding seats are equidistantly arranged on the upper end face of the support guide seat near the inside of the rubber sealing ring. An air guiding pipe is fixedly installed at the center of the lower end face of the support guide seat, and an exhaust hole is opened on the lower end face of the support guide seat directly opposite the detection air hole.

[0010] Preferably, the lower end face of the liquid-cooled plate housing is sealed and fitted to the upper end face of the rubber sealing ring, which can effectively improve the accuracy and stability of subsequent airtightness testing of the rivet holes and liquid-cooled plate cavity inside the liquid-cooled plate housing.

[0011] Preferably, the upper end face of the air guide seat does not contact the top wall of the inner end face of the liquid cooling plate cavity, which facilitates subsequent testing of the air hole and the liquid cooling plate cavity to form a sealed cavity, and facilitates subsequent rapid testing of the airtightness of the rivet hole and the liquid cooling plate cavity.

[0012] Preferably, the detection vent and the exhaust vent are connected in a continuous manner, and both the detection vent and the exhaust vent are coaxially aligned with the rivet hole. The detection vent and the exhaust vent are coaxial and of the same size, which facilitates the rapid discharge and detection of the gas discharged from the rivet hole, improving the convenience and stability of subsequent detection.

[0013] Preferably, the vent is connected to the visual inspection water tank through the docking air pipe, and the threaded guide shaft is threadedly connected to the threaded baffle, which facilitates subsequent workers to perform all-round limiting operations on the side wall of the liquid cooling plate box, thereby improving the accuracy and stability of the alignment between the liquid cooling plate box and the rubber sealing ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting up an air guiding device, allows for sufficient additional pressure to the rubber sealing ring and the interior of the liquid-cooled plate cavity during airtightness testing of the liquid-cooled plate cavity and rivet holes inside the liquid-cooled plate housing. This creates a sealed high-pressure chamber between the rubber sealing ring and the liquid-cooled plate cavity. Simultaneously, the detection vent, exhaust vent, connecting air pipe, and visual detection water tank form an airtightness testing channel. Furthermore, the airtightness of the liquid-cooled plate cavity and rivet holes can be quickly and intuitively determined through the detection water bubbles inside the visual detection water tank. This effectively improves the convenience and intuitiveness of the equipment for airtightness testing of the liquid-cooled plate cavity and rivet holes inside the liquid-cooled plate housing.

[0016] 2. This utility model, by setting up a rotating pressing cylinder and a rubber sealing ring, allows the rubber sealing ring to fit snugly against the bottom of the liquid-cooled plate housing, thereby effectively improving the sealing performance of the detection cavity formed between the liquid-cooled plate cavity and the rubber sealing ring, thus improving the accuracy of the detection. Furthermore, the uniform pressing of the upper part of the liquid-cooled plate housing by multiple sets of rotating pressing cylinders further improves the sealing performance between the liquid-cooled plate housing and the rubber sealing ring, thereby minimizing the probability of air leakage at the joint between the liquid-cooled plate housing and the rubber sealing ring, and improving the accuracy of the detection.

Detailed Implementation

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides an embodiment of an airtightness testing device for an aluminum extruded liquid cooling plate box, comprising an air guiding device 3 for support, aluminum profile columns 5 at the four corners of the lower end face of the air guiding device 3, ten sets of connecting air pipes 6 equidistantly arranged on the lower end face of the air guiding device 3, and a testing water tank 8 located at the side end of the ten sets of connecting air pipes 6.

[0025] Visual inspection water tank 4 is equidistantly arranged on the upper surface of inspection water tank 8, and is used to inspect air tightness.

[0026] Rotary pressing cylinder 2 is fixedly installed at equal intervals on the upper end face of air guiding device 3, and liquid cooling plate box 1 is fixedly connected to the upper end face of air guiding device 3 by rotating pressing cylinder 2. Liquid cooling plate cavity 9 is opened in the middle of the inner end face of liquid cooling plate box 1, and rivet holes 10 are opened at equal intervals on the side of the lower end face of liquid cooling plate box 1.

[0027] The threaded baffle 7 is provided in four sets, and all four sets of threaded baffle 7 are threadedly connected to the inner end face of the air guiding device 3. The threaded baffle 7 is used to limit the side of the liquid cooling plate box 1.

[0028] like Figure 4 and Figure 5 The air guiding device 3 includes a support guide seat 35. Four sets of threaded guide shafts 34 are equidistantly and rotatably engaged on the inner end face of the support guide seat 35. A rubber sealing ring 32 is provided on the upper end face of the support guide seat 35 near the outside. Detection air holes 31 are equidistantly opened on the upper end face of the rubber sealing ring 32 near the side. Three sets of air guiding seats 33 are equidistantly arranged on the upper end face of the support guide seat 35 near the inside of the rubber sealing ring 32. An air guiding pipe 36 is fixedly installed at the center of the lower end face of the support guide seat 35. An exhaust hole 37 is opened on the lower end face of the support guide seat 35 directly opposite the detection air hole 31.

[0029] like Figure 2 The lower end face of the liquid-cooled plate housing 1 is sealed and bonded to the upper end face of the rubber sealing ring 32, which can effectively improve the accuracy and stability of subsequent airtightness testing of the rivet holes 10 and the liquid-cooled plate cavity 9 inside the liquid-cooled plate housing 1.

[0030] like Figure 2 and Figure 4 The upper end face of the air guide seat 33 does not contact the top wall of the inner end face of the liquid cooling plate cavity 9, which facilitates the subsequent detection of the air hole 31 forming a sealed cavity with the liquid cooling plate cavity 9, and facilitates the subsequent rapid detection of the air tightness of the rivet hole 10 and the liquid cooling plate cavity 9.

[0031] like Figure 4 The detection vent 31 and the exhaust vent 37 are connected in a continuous manner, and both the detection vent 31 and the exhaust vent 37 are coaxially aligned with the rivet hole 10. The detection vent 31 and the exhaust vent 37 are coaxial and of the same size, which facilitates the rapid discharge and detection of the gas discharged from the rivet hole 10, thereby improving the convenience and stability of subsequent detection.

[0032] like Figure 3 and Figure 5The exhaust port 37 is connected to the visual inspection water tank 4 through the connecting air pipe 6, which facilitates the formation of a flow channel for air tightness detection by the subsequent air port 31, exhaust port 37, connecting air pipe 6 and visual inspection water tank 4, thereby improving the stability and visibility of the detection.

[0033] The threaded guide shaft 34 is threadedly connected to the threaded baffle 7, which facilitates subsequent workers to perform all-round limiting operations on the side wall of the liquid cooling plate box 1, thereby improving the accuracy and stability of the alignment between the liquid cooling plate box 1 and the rubber sealing ring 32.

[0034] Working principle: Before testing the airtightness between the liquid-cooled plate cavity 9 and the rivet holes 10 inside the liquid-cooled plate housing 1, the operator can sequentially introduce test water into ten sets of visible inspection water tanks 4. The operator can then lift the liquid-cooled plate housing 1 using an external hoisting module, align the liquid-cooled plate housing 1 with the rubber sealing ring 32, and lower it so that the bottom of the liquid-cooled plate housing 1 fits against the upper part of the rubber sealing ring 32. At the same time, the rivet holes 10 at the bottom of the liquid-cooled plate housing 1 are sealed and aligned with the inspection air holes 31. After the liquid-cooled plate housing 1 is positioned, the operator can hold the threaded guide shaft 34 and adjust the clamping force of the threaded baffle 7 on the side of the liquid-cooled plate housing 1 by rotating the threaded guide shaft 34. Simultaneously, multiple sets of rotating and pressing cylinders 2 are activated. The rotating downward cylinder 2 can rotate and move downward to press and limit the upper part of the liquid cooling plate box 1, thereby improving the airtightness between the lower part of the liquid cooling plate box 1 and the upper part of the rubber sealing ring 32. After the above operation is completed, the operator can ventilate the bottom of the air guide pipe 36 under high pressure. At this time, the air guide pipe 36 can vent the gas into the air guide seat 33. Since the rubber sealing ring 32 and the liquid cooling plate box 1 form a sealed structure, if there is a gap between the rivet hole 10 and the liquid cooling plate cavity 9, the gas can be introduced into the docking air pipe 6 along the exhaust hole 37, and then introduced into the visual inspection water tank 4 through the docking air pipe 6. At this time, air bubbles will appear in the visual inspection water tank 4. Conversely, the airtightness between the rivet hole 10 and the liquid cooling plate cavity 9 inside the liquid cooling plate box 1 is good.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
