Description

Hydraulic quick male connector, female connector and connector Technical Field The application relates to the field of hydraulic quick connectors, in particular to a hydraulic quick male connector, a hydraulic quick female connector and a hydraulic quick female connector. Background In recent years, with the rapid development of data centers, high Performance Computing (HPC) clusters, and supercomputers (supercomputers), the power density of internal chips and systems thereof continues to rise, and the requirements for heat dissipation efficiency reach unprecedented levels. The liquid cooling technology has become a key solution for meeting the heat dissipation requirement of the high-power density equipment by virtue of the excellent heat dissipation capability, and is applied and popularized in large scale in server clusters and supercomputers. Accordingly, the demand for high reliability hydraulic quick connectors (liquid cooled connectors) for connecting coolant lines has proliferated, and the demands for performance, reliability and maintenance convenience thereof have become increasingly stringent. In the prior art, hydraulic quick connectors are widely used in various liquid cooling systems. Typical quick connectors generally comprise two parts, a male connector and a female connector, which are sealed after connection by means of a sealing element such as an O-ring, and are quickly plugged and locked by a locking mechanism such as a ball, ferrule, or the like. However, with the popularity of liquid cooling systems in critical infrastructure (e.g., data centers, supercomputers) and increasing complexity of application environments, liquid cooled joints in the prior art expose the following significant drawbacks, which are difficult to meet the current high standard application requirements: In an environment where equipment such as a server room and a supercomputer is densely deployed, maintenance work is often performed in the case of insufficient light (e.g., in a cabinet, at night) or in the case of emergency. Existing linkers are generally lacking in efficient fluorescent or self-luminescent identification systems. The special connector is difficult to quickly and accurately position by professional maintenance personnel in a low-light environment, the connection point is identified, the efficiency is low, errors are easy to occur, and the downtime of the system is prolonged especially when the leakage point in a complex pipeline is checked or fault diagnosis is carried out. If the power calculation module fails (the temperature of the water cooling plate is too high), the temperature of the water outlet is changed from dark red to orange, and the failure position is indicated. Localized overheating of the joint may occur, which is a potential failure precursor or safety hazard. However, existing joints do not have an integrated temperature sensitive indication function. Maintenance personnel cannot predict the overheat problem by directly observing the state change of the connector, and usually, an additional temperature sensor or a complex monitoring system is needed, so that the complexity and the cost of the system are increased, the real-time performance is insufficient, and visual field early warning cannot be provided. Disclosure of utility model The application aims to provide a hydraulic quick male connector, a hydraulic quick female connector and a hydraulic quick connector, which can effectively solve the problems, particularly for the high-requirement data center and the super-computing center liquid cooling application scene, provide clear connection in-place indication, are easy to identify and position in a low-light environment, and can provide visual early warning for overheat of a cooling liquid outlet caused by faults of a computing power module and the like, thereby accurately positioning a fault source and remarkably improving the installation reliability, maintenance efficiency and operation safety of a liquid cooling system.
