A water-cooling radiator unit and a water-cooling module using same are disclosed. The water-cooling radiator unit includes a main body divided into a first section, a second section and a transit zone, which are fluidly communicable with one another. The first section has a first flow passage system and an inlet formed thereon, the second section has a second flow passage system and an outlet formed thereon. The main body is internally filled with a cooling fluid, and the transit zone has a pump mounted therein. The water-cooling radiator unit can be fluidly connected to a water block via two tubes to form a water-cooling module. The pump drives the cooling fluid to circulate in the main body and between the water-cooling radiator unit and the water block, enabling the water-cooling module to provide upgraded heat-dissipation performance while the water block has a reduced volume.

A heat exchanger for cooling particulate matter from a high-temperature industrial process or warming material from a cryogenic process is disclosed. The heat exchanger comprises a structure comprising a rectangular frame, piping that is supported by the rectangular frame and completes at least one circumference around the rectangular frame, and a fan. The piping is supported to the frame on a series of moving supports. The piping comprises an inlet end and an outlet end, and the piping contains external cooling fins. The structure is sealed except for where the finned piping is located.

A heat exchanger and an air-conditioning apparatus that exhibit high performance, and also provide reliability in strength and corrosion resistance. The heat exchanger includes a plurality of fins each including a fin collar formed in a short cylindrical shape by perforating a flat base plate, the plurality of fins being stacked by serially connecting fin collars of the respective fins, the serially connected fin collars being bonded to form a conduit line and a fin core, the conduit line including a resin layer formed on an inner surface thereof. The heat exchanger also includes a reinforcing member having a length corresponding to a length of the conduit line from one end to the other end thereof, to improve rigidity of the conduit line.

The present invention discloses a defrosting device, including: a heating unit provided at a lower portion of the evaporator; and a heat pipe connected to an inlet and an outlet of the heating unit, respectively, and having at least part thereof disposed adjacent to a cooling pipe of the evaporator such that the cooling pipe of the evaporator is cooled by a working fluid of high temperature which is transferred in a heated state by the heating unit, wherein the heating unit includes: a heater case extending in one direction to be arranged in a left and right direction of the evaporator, and having the inlet and the outlet at both sides thereof; and a heater provided with an active heating part accommodated within the heater case and actively generating heat to heat the working fluid, and a passive heating part extending from the active heating part and heated up to temperature lower than temperature of the active heating part, and wherein the inlet is formed at a position away from the active heating part to prevent the working fluid returned after flowing along the heat pipe from being introduced directly into the active heating part.

An additively manufactured finned-tube heat exchanger is provided and includes only a single part. The single part includes one or more tubular elements having tubular widths of less than 0.1 and being configured to define one or more first flow paths for a first fluid and two or more fins through which the one or more tubular elements extend. The two or more fins are arranged to define second flow paths over and around the one or more tubular elements for a second fluid.

In a vapor chamber and its upper casing member, the vapor chamber includes a lower casing, an upper casing member and a working fluid. The upper casing member is engaged and sealed with the lower casing, and a chamber is enclosed between the upper casing member and the lower casing. The upper casing member includes a substrate, plural fins and plural support bodies which are integrally formed with one another. The substrate has an outer surface and an inner wall disposed opposite to each other, and each fin is formed and extended from the outer surface, and each support body is formed and extended from the inner wall. The working fluid is filled in the chamber. Each support body is provided for conducting heat from the lower casing to each fin.

A reliable, leak-tolerant liquid cooling system with a backup air-cooling system for computers is provided. The system may use a vacuum pump and a liquid pump and/or an air compressor in combination to provide negative fluid pressure so that liquid does not leak out of the system near electrical components. Alternatively, the system can use a single vacuum pump and a valve assembly to circulate coolant. The system distributes flow and pressure with a series of pressure regulating valves so that an array of computers can be serviced by a single cooling system. A connector system is provided to automatically evacuate the liquid from the heat exchangers before they are disconnected. Leah detection and mitigation structures are also disclosed. Various turbulators are also provided, as well as a system and method for optimizing the heat transfer characteristics of a heat exchanger to minimize total energy requirements.
