A water seepage detection system for a deionized water cooling device

Abstract

The invention discloses a water seepage detecting system of a de-ionized water cooling device. The water seepage detecting system of the de-ionized water cooling device comprises a printed circuit board, a printing copper wire, a signal conditioning circuit and a digital controller, wherein the printing copper wire, the signal conditioning circuit and the digital controller are mounted on the print circuit board; the printing copper wire has a bifilar helix structure and comprises four ports; one input end is connected with the anode of a power supply while the other input end is connected with the ground; two output ends are connected with the input end of the signal conditioning circuit; the output end of the signal conditioning circuit is connected with the digital controller; one surface of the print circuit board is upwardly placed at a water pipe connector in the de-ionized water cooling device; when water leaks, water drops are sprayed to the printing copper wire to change the impedance of the output end of the printing copper wire; the signal conditioning circuit converts the impedance change of the output end into a voltage signal and amplifies the voltage signal; and the digital controller compares the amplified voltage signal with a voltage threshold and outputs the water seepage state according to the comparative result. The water seepage detecting system of the de-ionized water cooling device has the advantages of high sensitivity, quick response, convenience in use, long service life and low maintaining cost.

Description

technical field [0001] The invention belongs to the technical field of deionized water cooling, and more specifically relates to a water seepage detection system of a deionized water cooling device. Background technique [0002] The deionized water cooling device transports the deionized water to the corresponding heat source through the water pump and the water pipe network, and realizes heat dissipation through the deionized water flowing in the pipe. There are many pipes in the cooling device, and some pipes are sealed at the same time. If a water leak occurs, it cannot be seen. The traditional method is to use chemical reagents such as color-changing silica gel that change color when exposed to water to indicate the water leakage of the system and the location of the water leak. [0003] There are three shortcomings of the traditional method. The first is that the sensitivity of detecting water leakage is not high, and the chemical reagent can only change color after abs...
