High-pressure air tightness detection device for air conditioner heat exchange coil pipe

The invention discloses an air conditioner heat exchange coil pipe high pressure air tightness detection device, which comprises an air tightness detection tank, a suction driving unit, a suction mechanism and a detection rack, and is characterized in that the suction mechanism is fixedly installed on the surface of the suction driving unit and is in transmission connection with the output end of the suction driving unit, and the detection rack comprises an operation rod, a material rack, a support frame and a detection cable; the suction driving unit is fixedly installed on one side of the supporting frame. According to the invention, the negative pressure detection structure is arranged, and the suction driving unit and the suction mechanism work to suck the internal environment of the airtightness detection tank to form a negative pressure environment, so that a relatively high pressure environment is formed in the to-be-detected air conditioner heat exchange coil in the airtightness detection tank to effe
