AI Technical Summary
Technical Problem
The prior art lacks a special airtightness test device to conduct airtightness testing on the aluminum radiator core of the locomotive cooling tower, resulting in inaccurate test results.
Method used
A gas-tightness test device for core of cooling tower radiator is designed, including a first pressure plate and a second pressure plate. The sealing plate of the radiator core is sealed by these pressure plates, and a gas delivery port and a pressure detection port are provided. By injecting air and maintaining a certain pressure, the sealing property of the core flow channel is detected.
Benefits of technology
The device can completely seal the radiator core, ensure the accuracy of air tightness tests, and quickly locate the air leakage points and improve the test efficiency.

Abstract
The utility model discloses an air tightness test device for a cooling tower radiator core body, which relates to the technical field of air tightness test devices and comprises a radiator core body, a plurality of flow channels are arranged at two ends of the radiator core body, sealing plates are respectively arranged at two ends of the radiator core body, and a plurality of air holes are arranged on the sealing plates. The runners at the two ends of the radiator core body correspond to the air holes of the sealing plates at the two ends respectively; the first pressing plate and the second pressing plate are used for sealing the sealing plates at the two ends respectively; the first pressing plate is provided with a gas conveying port and a pressure detection port, the gas conveying port is communicated with a gas source through a pipeline, and the pressure detection port is communicated with a pressure gauge through a pipeline. According to the device, the radiator core body is sealed and then placed into the water tank together, air is injected into the core body and pressure is maintained, whether a flow channel of the radiator core body is qualified or not is judged by detecting whether air leakage occurs or not, the specific leakage point position can be quickly confirmed, the accuracy of an air tightness test is ensured, and the test efficiency is improved.
