The detection plate is fixedly arranged on the main frame, and an airtight pipeline assembly is arranged on the detection plate. The fixing clamp is fixedly arranged on the main frame for fixing the liquid cooling plate, and also includes a sliding part. The sliding part is fixedly arranged in the main frame for guiding the liquid cooling plate so that the water inlet and outlet of the liquid cooling plate are connected to the airtight pipeline assembly. By setting a sliding part, this device can guide the liquid cooling plate so that its water inlet and outlet are quickly connected to the airtight pipeline assembly, thereby improving the detection efficiency of the airtightness testing device.
