Abstract: A two-phase cooling system is provided, including a closed tank; a condensing module, having a plurality of condenser tubes, where the plurality of condenser tubes are located above an interior of the closed tank and arranged longitudinally at intervals; and a plurality of flow directors, where each of the flow directors has at least one inclined plate and at least one engagement portion, the engagement portion is connected to the inclined plate, the engagement portion is engaged with any one of the condenser tubes or the closed tank, and the inclined plate extends between two adjacent condenser tubes.

Abstract: An apparatus for automated maintenance, adapted for maintaining an airtight equipment comprises airtight equipment including a casing, which forms an accommodation space and is adapted to accommodate an equipment component in the accommodation space. The apparatus for automated maintenance includes an automated maintenance machine, adapted to store and transport the equipment component, an enclosure, connected to the automated maintenance machine, the enclosure forming an enclosure space and selectively connected to the airtight equipment via an enclosure opening such that the enclosure space is in communication with the accommodation space and forms airtightness. A robotic arm, disposed in the enclosure space, is adapted to enter the accommodation space to maintain or replace the equipment component of the airtight equipment, and further adapted to enter the automated maintenance machine to take and place the equipment component.

Abstract: A passive liquid recycle device for solving an issue of inappropriate pressure regulation often occurring in a conventional two-phase immersion cooling device. The passive liquid recycle device is adapted to be in communication with a two-phase immersion cooling device, and includes a housing and at least a bag, accommodated in a volume variable manner in the housing. The bag being higher than the two-phase immersion cooling device and capable of passively receiving a gaseous coolant from the two-phase immersion cooling device and accordingly expanding, and contracting after the gaseous coolant condenses into a liquid coolant and returns to the two-phase immersion cooling device.

Abstract: An airtight switch adapted for an airtight device comprises an enclosure and a lid structure which are adapted to be joined with each other at a junction plane. The airtight switch includes a slider disposed at one of the enclosure or the lid structure. The airtight switch includes a contact element disposed at the other of the enclosure or the lid structure. The contact element has a sloped surface, and the slider selectively abuts against the sloped surface. The airtight switch includes a linear drive device adapted to drive the slider to move linearly in a sliding direction. The sliding direction is parallel to the junction plane and non-perpendicular to a normal vector of the sloped surface. The airtight switch is adapted to be applied in an airtight device needing a switch with good sealing and airtightness.
