Dry leak testing machine

Abstract

The invention belongs to device detection equipment, and in particular relates to a dry leak testing machine. The dry leak testing machine mainly comprises a vertical bracket, a longitudinal cylinder, a transverse cylinder and an airtight leak detector, wherein the vertical bracket comprises an upper workbench and a lower workbench by a fixing column; the airtight leak detector is arranged on the upper part of the workbench, and the longitudinal cylinder is fixed on the lower part; the lower workbench is provided with a bottom plate; an air duct is arranged in the bottom plate and is connected with the air outlet of the airtight leak detector via an air tube; one side of the transverse cylinder, which is arranged on the bottom plate, is fixed on the lower workbench; and the transverse cylinder piston of the transverse cylinder is provided with a sealing plug. The dry leak testing machine has the beneficial effects that a workpiece is fixed by the longitudinal cylinder; a through hole of a heat dissipation device is plugged and sealed by the transverse cylinder, and a large electronic device radiator is pressurized in a sealed mode so as to observe the air pressure situation of the airtight leak detector to determine whether the radiator is leaked. A test result is intuitive, accurate and efficient, and the quality of the electronic device radiator is greatly guaranteed.

Description

technical field [0001] The invention belongs to device testing equipment, in particular to a dry leak testing machine. Background technique [0002] The large-scale electronic device radiator has several cooling fins installed in the communication device of the base station. The dial or button of the communication device leaks out of the radiator, so that several through holes are left on the side wall of the radiator when the radiator is cast. There is a sealing ring on the hole, and the sealing ring is closely matched with the dial and the button to ensure the airtightness inside the radiator, but because it is exposed to the outdoor air for a long time, in the face of various complicated weather, if the sealing of the radiator is not good It will cause a short circuit of the internal electronic devices and cause premature damage to the communication device. Therefore, it is very important to detect water leakage and air leakage of radiators. At present, there is no speci...

[0002] The large-scale electronic device radiator has several cooling fins installed in the communication device of the base station. The dial or button of the communication device leaks out of the radiator, so that several through holes are left on the side wall of the radiator when the radiator is cast. There is a sealing ring on the hole, and the sealing ring is closely matched with the dial and the button to ensure the airtightness inside the radiator, but because it is exposed to the outdoor air for a long time, in the face of various complicated weather, if the sealing of the radiator is not good It will cause a short circuit of the internal electronic devices and cause premature damage to the communication device

Therefore, it is very important to detect water leakage and air leakage of radiators. At present, there is no special detection equipment for water leakage and air leakage detection of radiators with dial holes or button holes, which makes the air tightness detection of radiators for large electronic devices blank. , unable to meet the requirements of high-quality products under the fierce market competition
