[0031] In order to make the purpose, technical solution and advantages of the embodiment of the present disclosure more clear, the embodiment of the present disclosure is further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation methods described here are only used to explain the embodiment of the present disclosure and are not used to limit the embodiment of the present disclosure.

[0032] like Figure 1As shown, the embodiment of the present disclosure proposes a tool for detecting the air tightness of a refrigerant radiator with a transition pipe, which is applied to a refrigerant radiator with a transition pipe, and the tool comprises: a tool body 1, which is provided with an open accommodating cavity for accommodating a refrigerant radiator 7 with a transition pipe, and the accommodating cavity is located on a side wall of the transition pipe and is provided with an opening for the transition pipe to pass through, wherein the transition pipe comprises a liquid inlet pipe and a liquid outlet pipe; a front block 2, which is detachably arranged on the side wall of the tool body provided with the opening, and the front block is provided with an air hole corresponding to one of the pipe openings of the transition pipe, and the air hole is used to connect a high-pressure gas conveying device to convey the detection gas to the refrigerant radiator; a sealing gasket 3, which has a through hole, one end of which is arranged at the pipe opening of the transition pipe of the refrigerant radiator, and the other end exposes the pipe opening of the transition pipe; when the front block is arranged on the side wall of the tool body, the end of the transition pipe abuts against the front block, and the sealing gasket seals the pipe opening of the other transition pipe.

[0033] The tooling body 1 of the embodiment of the present disclosure processes the central area to mill out a groove that is consistent with the outer contour of the refrigerant radiator to be tested, that is, a receiving cavity. The front block 2 and the side wall of the tooling body provided with the opening are respectively provided with corresponding threaded holes, and the front block 2 can be detachably connected to the tooling body by M10 screws. After the front block 2 is fixed to the tooling body by screws, the pipe mouth of the transition pipe of the refrigerant radiator abuts against the front block 2, and the sealing gasket is located between the front block and the tooling body to achieve sealing of the transition pipe mouth of the refrigerant radiator. There are two sealing gaskets 3, which are respectively installed at the pipe mouths of the copper-aluminum transition pipe of the radiator. The front block is provided with an air hole, and the air hole is provided with a thread for connecting with a quick-connect connector to connect the equipment for delivering high-pressure gas to the refrigerant radiator. After placing the refrigerant radiator in the accommodating cavity of the tooling body, assemble the front block, connect the high-pressure gas through the G1 / 4 external interface on the front block, and then immerse the product and tooling in water to check for leaks.

[0034] Specifically, when testing the air tightness of the refrigerant radiator, place the refrigerant radiator in the accommodating cavity of the tooling body and install the front blocking block; after connecting the quick-connect connector through the air hole of the front blocking block, connect the high-pressure gas equipment to deliver high-pressure gas to the refrigerant radiator; immerse the tooling, the refrigerant radiator and related components connected to the high-pressure gas, such as pipelines, in water to test the sealing performance of the refrigerant radiator, especially the sealing performance of the welding point between the refrigerant radiator body and the transition pipe.

[0035] The sealing gasket has two parts, which are respectively arranged at the pipe openings of the liquid inlet pipe and the liquid outlet pipe; the first end of the sealing gasket is inserted into the pipe opening of the transition pipe, and the diameter of the second end of the sealing gasket is slightly larger than that of the first end, so that the second end of the sealing gasket is exposed outside the pipe opening of the transition pipe. When the front block is arranged on the side wall of the tooling body, both ends of the transition pipe can abut against the front block, wherein one sealing gasket seals the pipe opening of the other transition pipe, and the other sealing gasket can also seal the connection between the front block and one of the transition pipes. In this way, when one of the transition pipes is connected to high-pressure gas, the connection is also in a sealed state, and gas is only transported to the refrigerant radiator through the air holes.

[0036] The detection tooling provided in the embodiment of the present disclosure can be widely used in the process of air tightness detection of refrigerant radiators with copper-aluminum transition tubes. Specifically, the refrigerant heat dissipation technology usually adopts refrigerants (such as Freon) to circulate in electronic equipment to achieve the purpose of heat dissipation. During the circulation process, the refrigerant absorbs and releases heat through evaporation and condensation, thereby achieving heat dissipation. The battery pack is constantly charging and discharging stages, converting electrical energy into thermal energy, releasing a large amount of heat, and the heat is transferred to the radiator. Through the circulation of the coolant inside the radiator, the heat is taken out of the battery pack, so that the battery pack is stabilized within a certain temperature range, ensuring the normal operation of the battery and extending the service life of the battery. In the refrigerant radiator in the embodiment of the present disclosure, the body has a flow channel for the circulation of refrigerant, and the body is welded with a liquid inlet pipe and a liquid outlet pipe respectively connected to the inlet and outlet of the flow channel, which are collectively referred to as transition pipes. The detection tooling is generally used to detect the sealing performance of the refrigerant radiator, especially the sealing performance of the refrigerant radiator body and the welding part between the transition pipe and the refrigerant radiator body.

[0037] Advantages of the detection tooling of the disclosed embodiment: 1) Because the outer wall of the copper-aluminum transition tube is smooth and has no clamping position, the traditional inspection tooling is usually designed with two vertical clamping to achieve a sealing effect during inspection. A clamp is made perpendicular to the axial direction of the tube as a fixed point, and then the copper-aluminum transition tube is clamped and tightened along the axial direction of the tube, and finally a high-pressure gas is passed to detect whether the product is leaking. Because it involves two clampings in different directions, the sealing between the tooling itself and the copper-aluminum transition tube directly affects the detection effect. And the two clamping operations affect efficiency. 2) The disclosed embodiment has made improvements to the above-mentioned traditional inspection tooling. Combined with the structural characteristics of the product, the copper-aluminum transition tube has a smooth outer wall and no card points. The disclosed embodiment uses the structure of the radiator to find a suitable card point. In this way, it only needs to be clamped along the axial direction of the tube to test the sealing of the product. The detection tooling of the disclosed embodiment has a simple structure and is easy to use.

[0038] As a specific example of the accommodating cavity, the shape and size of the accommodating cavity match the shape and size of the refrigerant radiator with the transition pipe.

[0039] The accommodating cavity of the detection tooling of the disclosed embodiment can be designed according to the actual shape of the radiator to be detected, as long as the accommodating cavity matches the shape and size of the refrigerant radiator to be detected. Compared with the tooling for clamping the transition pipe for sealing detection, it is more convenient to use and eliminates the detection step of clamping twice.

[0040] The tooling body of the disclosed embodiment is slotted according to the product's outline, and the slot body is consistent with the product except for the necessary clearance for loading and unloading the product, thus avoiding deformation of the copper-aluminum transition tube due to stress.

[0041] As a specific example of the tooling, the tooling further includes: a gasket 4, which is arranged on the side wall of the accommodating cavity opposite to the side wall on which the front blocking block is installed.

[0042] The gasket 4 described in the detection tooling of the disclosed embodiment is pasted on the tail end of the accommodating cavity of the tooling body, and the side opposite to the installation of the front block is the tail end of the accommodating cavity. The end of the refrigerant radiator body opposite to the transition pipe is the tail end of the refrigerant radiator. Tighten the M10 screws of the front block and the tooling body, and the front block 2 moves toward the tooling body 1. The sealing gasket 3, the product and the gasket 4 between the two are squeezed, so that the refrigerant radiator to be tested and the tooling body become tight, which is not easy to loosen during testing, and plays a role in protecting the refrigerant radiator body and preventing the product from colliding with the tooling.

[0043] As a specific example of a gasket, a notch 12 is set in the central area of ​​the side wall of the accommodating cavity opposite to the side wall on which the front block is installed, and the notch 12 is used to observe the rear part of the refrigerant radiator body; the gasket 4 has two side walls, which are respectively set on both sides of the notch 12 and opposite to the side wall of the accommodating cavity opposite to the side wall on which the front block 2 is installed.

[0044] In the embodiment of the present disclosure, a notch is formed at the rear end of the tool body, so as to facilitate observation of whether the welding at the rear end of the radiator is leaking during inspection.

[0045] like Figure 3 As shown, as a specific example of the accommodating cavity, the bottom wall of the accommodating cavity is provided with an observation port 11 at the connection between the refrigerant radiator body and the transition pipe, and the observation port 11 is used to observe the welding portion between the transition pipe of the refrigerant radiator and the refrigerant radiator body.

[0046] In the embodiment of the present disclosure, the tool body is hollowed out according to the position where the air tightness of the refrigerant radiator product to be tested needs to be tested. For example, there is a risk of leakage at the welding point between the copper-aluminum transition pipe and the radiator, so the tool is hollowed out at this position to form an observation port, which is convenient for operators to observe the leakage.

[0047] As a specific example of the accommodating cavity, the accommodating cavity includes: a first groove (not shown in the figure) for accommodating the body of the refrigerant radiator with a transition pipe; a second groove (not shown in the figure) for accommodating the transition pipe of the refrigerant radiator with a transition pipe.

[0048] The accommodating cavity of the detection tooling of the embodiment of the present disclosure matches the shape and size of the refrigerant radiator to be tested. The refrigerant radiator to be tested in the embodiment of the present disclosure includes a body and a transition pipe, the transition pipe includes a liquid inlet pipe and a liquid outlet pipe, the liquid inlet and the liquid outlet of the refrigerant radiator body are arranged adjacent to each other, the front half of the transition pipe is arranged adjacent to each other, and the rear half is separated by a certain distance. Therefore, for this shape of refrigerant radiator, the detection tooling structure of the embodiment of the present disclosure is specifically designed as follows.

[0049] like Figure 2 As shown, as a specific example of the accommodating cavity, the shape of the first groove is the same as the body shape of the refrigerant radiator with transition pipe, and the sizes of the two are matched;

[0050] The second groove includes a front half and a rear half, the front half is connected to the first groove, and is used to accommodate the adjacent liquid inlet pipe and liquid outlet pipe of the transition pipe, and the rear half is provided with a liquid inlet pipe groove for accommodating the liquid inlet pipe and a liquid outlet pipe groove for accommodating the liquid outlet pipe, and a partition block is provided between the liquid inlet pipe groove and the liquid outlet pipe groove.

[0051] In the disclosed embodiment, for example, the main body of the refrigerant radiator is in the shape of a rectangular structure, then the first groove is also in the shape of a rectangular structure, and its size matches the main body of the refrigerant radiator; the transition pipe of the refrigerant radiator is divided into a front half connected to the main body of the refrigerant radiator and a rear half separated and spaced apart, so that the shape and size of the second groove must correspond to the transition pipe of the refrigerant radiator, and is also divided into a front half and a rear half, the front half accommodating the adjacently arranged liquid inlet pipe and liquid outlet pipe of the transition pipe, and the rear half separately accommodating the liquid inlet pipe and the liquid outlet pipe.

[0052] As a specific example of a tooling body, the tooling body is provided with first threaded holes 6 at both ends of the side walls of the transition pipe port of the refrigerant radiator and the partition block, and the front blocking block is provided with second threaded holes 5 corresponding to the first threaded holes, and the first threaded holes 6 and the second threaded holes 5 are connected by screws.

[0053] In the disclosed embodiment, the front blocking block is connected and fixed to the tooling body by three sets of screws, and the fixation is uniform to ensure the sealing performance.

[0054] As a specific example of the first groove, the two opposite side walls of the first groove are provided with buckle parts.

[0055] The buckle handle of the embodiment of the present disclosure facilitates taking out the refrigerant radiator body.

[0056] As a specific example of the grip portion, the grip portion is an arc-shaped groove that avoids into the side wall of the first groove.

[0057] The buckle handle of the embodiment of the present disclosure has a simple structure and is easy to process.

[0058] The above is only a preferred implementation of the embodiment of the present disclosure. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the embodiment of the present disclosure. These improvements and modifications should also be considered as the protection scope of the embodiment of the present disclosure.
