Leakage detection device

Abstract

This disclosure provides a leak detection device, including: a water cooling head; a plurality of pipes disposed on the water cooling head; a sensing unit disposed on the water cooling head, and including a first patterned line and a second patterned line facing the plurality of pipes, wherein the first patterned line and the second patterned line do not intersect each other; and a control unit connected to the first patterned line and the second patterned line for detecting impedance changes in the loop formed by the first patterned line and the second patterned line.

Claims

1. A leak detection device, comprising: A water cooling block has a first side and a second side facing each other, the first side being used to contact a heat source; A plurality of pipes are disposed on the second side of the water cooling head; a sensing unit is disposed on the second side of the water cooling head and includes a first patterned line and a second patterned line facing the plurality of pipes, wherein the first patterned line and the second patterned line do not intersect each other; and a control unit is connected to the first patterned line and the second patterned line to detect the impedance change of the loop formed by the first patterned line and the second patterned line.

2. The leak detection device as described in claim 1, wherein, When a liquid leaks from the multiple pipelines and the liquid drips onto the sensing unit, the liquid forms a loop with the first patterned line and the second patterned line.
