The utility model discloses an
air tightness detection tool for inlet and outlet pipelines of a high-
voltage battery cooler, and belongs to the technical field of battery coolers. The
air tightness detection tool for the inlet and outlet pipeline of the high-
voltage battery cooler comprises a device shell, an
air pump is installed at the upper end of the device shell, an air
pressure sensor is installed in the device shell, and two
extrusion sealing semi-rings are installed in each of two clamping frames. The
air tightness detection device solves the problems that an existing air tightness detection structure is single in structure, pipelines at different positions are inconvenient to adjust, and continuous detection work is affected, the positioning nut is screwed to drive the
threaded rod to rotate, and the threaded sleeve pushes the
extrusion sealing semi-rings, so that the two
extrusion sealing semi-rings clamp an inlet
pipe and an outlet
pipe, and the detection efficiency is improved. And the inlets and outlets in the two sides of the device shell are closed, so that airtightness detection work is facilitated, continuous detection work is facilitated, long-term use is facilitated, and the working efficiency is improved.
