AI Technical Summary
The airtightness test results of existing cold plate heat exchanger pipe fittings are inaccurate and costly, mainly due to the excessively thin bamboo-joint water taps.
A novel helium detector fixture with internal expansion and inclined surface sealing is designed, including a fixture housing, clamps, limit screws, internal positioning blocks, an internal sealing O-ring and an inclined surface O-ring. The fixture clamps the water nozzle and uses internal air pressure to expand the O-ring outward, achieving a double seal and ensuring airtightness.
This improves the accuracy of airtightness testing and reduces production costs for enterprises.
