Device for detecting liquid leakage of liquid cooling pipe of server

Abstract

The invention discloses a device for detecting the liquid leakage of a liquid cooling pipe of a server, and the device comprises the following parts: a flexible printed circuit board which wraps the liquid cooling pipe, wherein the inner layer of the flexible printed circuit board is provided with an exposed power line and an exposed signal line, and the power line and the signal line are arrangedat an interval; and a main board which is connected with the plurality of flexible printed circuit boards through cables, wherein the main board comprises a CPLD, and the CPLD is configured to receive signals from the plurality of flexible printed circuit boards about the conduction state between the power lines and the signal lines, judge whether the signals are abnormal or not, and turn off theserver power supply in response to the abnormity in the signals. According to the scheme provided by the invention, a liquid cooling pipe is wrapped by the flexible printed circuit board, the leakedliquid is effectively prevented from dropping to the main board, the detection of the leaked liquid of the board card is realized by utilizing the exposed signal wire of the inner layer of the flexible printed circuit board, the number of cables and fixing structural members in the server is reduced, and the wiring of the cables in the server is facilitated.

Description

technical field [0001] The invention relates to the field of servers, and more specifically, to a device for detecting liquid leakage from a liquid cooling pipe of a server. Background technique [0002] In data centers and other occasions where there are a large number of server applications, in order to improve the performance of a single node, multiple CPUs or GPUs are planned in the node. When the node is working, a large amount of heat will be generated. Traditional fan technology has low heat dissipation efficiency and high noise, which makes it difficult to meet its heat dissipation requirements. For this reason, the industry proposes to use liquid cooling to improve the heat dissipation effect, so as to achieve the purpose of reducing system power consumption and saving costs. [0003] The liquid cooling solution generally adopts the method of arranging corresponding pipes in the chassis to allow the cooling liquid to circulate continuously in the pipes to take away...

AI Technical Summary

Problems solved by technology

After the liquid leakage is detected, it can only call the police, but it cannot prevent the coolant from seeping into the main board, causing damage to the board

At the same time, the layout of the liquid leakage detection cable and the small detection board is required, that is, the structural parts of the chassis must be reserved for a fixed position to occupy the space of the chassis, and the complexity of cable wiring in the chassis is increased.
