Technical Field

[0001] The utility model relates to the technical field of double-channel radiators, in particular to a double-channel radiator air flow test tool. Background Art

[0002] According to the current design requirements of dual-channel radiators, the radiator has two independent processes, a high-temperature process and a low-temperature process; during the production process, it is necessary to use water immersion and air pressure to perform a sealing test, and the sealing test needs to detect external leakage of the two processes and internal cross-flow leakage between the two processes; in the past, two sets of tooling were used to perform two sealing tests to detect external leakage and cross-flow leakage respectively, and the test tooling needed to be installed twice, affecting production efficiency. Utility Model Content

[0003] The technical problem solved by the utility model is to provide an air leakage test tool for a double-channel radiator, which can complete the airtight test of a high-temperature process and a low-temperature process by using one set of tool.

[0004] The technical solution adopted by the utility model is a double-channel radiator air flow test tool, including an air intake end plate, an air intake pipeline, and a blind plate. Two air paths are arranged on the air intake end plate, and the two ends of the first air path are respectively connected to the high-temperature process of the radiator and the first air intake pipeline, and the two ends of the second air path are respectively connected to the low-temperature process of the radiator and the second air intake pipeline. A main valve is arranged on the first air intake pipeline, and a detection branch is also connected to the first air intake pipeline. The access point of the detection branch is between the main valve and the air intake end plate, and a secondary valve is arranged on the detection branch. The other end of the high-temperature process and the low-temperature process of the radiator are blocked by a blind plate, and a sealing gasket is arranged between the blind plate and the radiator. After the first air intake pipeline and the second air intake pipeline are connected in parallel, the gas source is provided by the total air intake pipeline.

[0005] Both the main valve and the auxiliary valve are ball valves.

[0006] A sealing gasket is provided between the high-temperature process and the low-temperature process of the air intake end plate and the radiator.

[0007] The end of the detection branch is a gas cross-talk detection port, which is connected to the atmosphere and can be connected to a hose. The end of the hose is inserted into water to facilitate observation of whether there is gas coming out.

[0008] The beneficial effects of the utility model are simple structure and great convenience in use. One set of equipment can realize two air tightness detection tasks and meet the requirements of double-channel radiator cross-flow test, saving time and effort, while reducing the labor intensity of the operator, improving production efficiency, reducing auxiliary working hours, and saving production costs.

DETAILED DESCRIPTION

[0014] The utility model will be further described below in conjunction with the accompanying drawings.

[0015] The purpose of this application is to design a dual-channel radiator cross-flow test tool. By using this tool, the test reliability is ensured, the operation is convenient, the operator's labor intensity is reduced, and the production efficiency is improved.

[0016] The double-channel radiator cross-flow test tool of the present invention comprises an air intake end plate, an air intake pipeline, a blind plate and a sealing gasket, wherein the air intake pipeline is composed of a ball valve, an air pipe and a joint; Figure 1 , Figure 2 shown.

[0017] Two air paths are provided on the air intake end plate 1, and the two ends of the first air path are respectively connected to the high-temperature process 12 of the radiator and the first air intake pipeline 1, and the two ends of the second air path are respectively connected to the low-temperature process 32 of the radiator and the second air intake pipeline 2. The upper end surface of the air intake end plate 1 is provided with an air inlet for the high-temperature process and an air inlet for the low-temperature process, which are respectively connected to the high-temperature process 31 and the low-temperature process 32 of the radiator, and sealing gaskets are provided at the connections.

[0018] The lower end surface of the air intake end plate 1 is connected to the first air intake pipeline 1 and the second air intake pipeline 2 through a connecting pipe and a fastener. A main ball valve 11 is provided on the first air intake pipeline 1. A detection branch 6 is also connected to the first air intake pipeline 1. The access point of the detection branch 6 is between the main ball valve 11 and the air intake end plate 1. A secondary ball valve 61 is provided on the detection branch 6. The other ends of the high-temperature process 22 and the low-temperature process 12 of the radiator are blocked by a blind plate 4. A sealing gasket is provided between the blind plate and the radiator. After the first air intake pipeline 1 and the second air intake pipeline 2 are connected in parallel, the gas source is provided by the main air intake pipeline.

[0019] like Figure 1-Figure 3As shown in the comparison, when the two ball valves are opened and closed in different forms, two detection methods can be formed. The end of the detection branch 6 is provided with a cross-flow detection port, which is connected to the atmosphere. The end can be connected to a hose and immersed in water. If there is a leak, bubbles will be generated. Intrusion detection in water is intuitive and convenient. Other conventional means can also be used to determine whether there is gas coming out of the cross-flow detection port.

[0020] like Figure 1 As shown, when in use, when the main ball valve 11 on the first air intake main path 1 connected to the high-temperature process 31 is opened and the secondary ball valve 61 on the detection branch 6 is closed, the high-temperature process 31 and the low-temperature process 32 of the radiator are simultaneously inlet, which is used to detect whether there is external leakage.

[0021] like Figure 2 As shown, when the main ball valve 11 on the first air intake main path 1 connected to the high-temperature process 31 is closed and the secondary ball valve 61 on the detection branch 6 is opened, the low-temperature process 32 of the radiator takes in air, and the high-temperature process 31 does not take in air, which is used to detect internal cross-flow leakage.

[0022] When there is a leak between the high temperature process 31 and the low temperature process 32, the air flow condition is as follows Figure 3 As shown, the gas in the low-temperature process 32 will enter the high-temperature process 31, and bubbles will be generated from the cross-flow detection port 62 of the detection branch 61, reminding the operator that there is a cross-flow leakage between the high-temperature process and the low-temperature process.

[0023] The double-channel radiator cross-flow test tool of the present application is very convenient to use, saves time and effort, can meet the double-channel radiator cross-flow test requirements, reduce the labor intensity of the operator, improve production efficiency, reduce auxiliary working hours, and save production costs.
