The liquid/gas separator is connected to the core-in-shell heat exchanger via a first line for transmitting gas from the liquid/gas separator to a first region in the core-in-shell heat exchanger and connected to the core-in-shell heat exchanger via a second line for transmitting liquid from the liquid/gas separator to a second region of the core-in-shell heat exchanger.

The present invention relates to an integrated connector and a heat exchanger including the same, in which a connector main body is formed by pressing one pipe, a cap is press-fitted into the connector main body, such that the integrated connector is formed so that an interior of the connector main body is blocked by the cap. Therefore, the number of components used to manufacture a connector, which connects and securely couples a header tank and a gas-liquid separator, may be reduced, the integrated connector may be easily manufactured, and a brazing defect may be reduced at portions where the integrated connector is joined to the header tank and the gas-liquid separator of the heat exchanger.

A water-replenishing and gas-removing structure for water cooling device includes a flow-guiding main body having a water-receiving space as well as an inlet, an outlet, a first opening and a second opening, which are communicable with the water-receiving space. The first and the second valve member are located in the water-receiving space corresponding to the first and the second opening, respectively, for opening or closing them. The first and the second connecting member are connected at an end to the first and the second opening, respectively, and at another end to an external water-replenishing and an external gas-removing apparatus, respectively, via a pipe each. With these arrangements, cooling fluid can be replenished into and surplus gas can be removed from a water cooling device without the need of disassembling or reworking the water cooling device.

An engine coolant separator may include a housing having an inlet and an outlet; and a guide member fixedly mounted inside the housing, and having a spiral channel inducing a spiral flow of an engine coolant, wherein the spiral channel communicates with the inlet of the housing.

Provided is a heat exchanger, including: a first heat exchange unit, which includes a first flat tube; a second heat exchange unit, which is arranged so as to be opposed to the first heat exchange unit, and includes a second flat tube; and a tank, which connects the first heat exchange unit and the second heat exchange unit to each other. The tank has an upper wall and a lower wall defining an upper end and lower end of a tank space formed in the tank, respectively. One end of the first flat tube and one end of the second flat tube are connected to the tank space. When a height from the lower wall to the upper wall is defined as X, and a height from the lower wall to the one end of the first flat tube is defined as Y1, a relation between X and Y1 satisfies Y1<()X.

A method for dismantling a steam generator or heat exchanger, such as found in nuclear power plants, which steam generator or heat exchanger includes a plurality of primary circuit tubes with a contaminated inner surface and wherein one or more tubes are sealed with a plug at both end is provided, the method comprising a) opening one or both ends of each sealed tube by creating an opening in or removing, the plug (13); b) introducing a viscous polymer to cure inside the tube wherein the polymer fills the tube across the full tube cross-section at least at the tube ends, immobilizing contaminations in the filled portion inside the tube (11); c) curing the polymer, then detaching the tubes with cured polymer the detached tubes being sealed by the polymer d) sorting out the detached tubes with polymer.

The invention relates to a heat exchanger assembly with at least one multi-pass heat exchanger, comprising a first distributor (1) with a first connection part (1a) for connecting to a fluid line (9), a second distributor (2) with a second connection part (2a) for connecting to a fluid line (9), and at least one first deflection distributor (4), as well as a plurality of tube lines (5) through which a fluid, in particular water, can flow, wherein the first distributor (1) and the second distributor (2) are arranged at one end (A) of the heat exchanger assembly, the deflection distributor (4) is arranged at the opposite end (B) and the tube lines (5) extend from the one end (A) to the opposite end (B), and wherein the first connection part (1a) is arranged at a lowest point (T) or at least near to the lowest point (T) of the first distributor (1) and the second connection piece (2a) is arranged at a lowest point (T) or at least near to the lowest point (T) of the second distributor (2). In order to allow for the heat exchanger assembly to be quickly filled with the fluid and quickly emptied, a third connection part (3) is arranged on the first distributor (1) and/or on the second distributor (2) at a highest point (H) or at least near to the highest point (H) of the respective distributor (1 or 2), and at least one ventilation opening (10) is provided at a highest point (T) or at least near to the highest point (T) of the deflection distributor (4) for pressure equalisation with the environment.

A liquid-cooling device having a liquid-gas isolation mechanism includes a tank, a first conduit, a second conduit, and a liquid-gas isolation mechanism. The tank has an outer wall, a first end, and a second end, and a liquid storage space is surrounded and defined by the outer wall, the first end, and the second end. The first conduit and the second conduit are partially disposed in the tank, and are respectively used for leading the cooling liquid in and out. The liquid-gas isolation mechanism includes at least a baffle disposed in the liquid storage space, and a plurality of flow holes are defined by the baffle and the outer wall. The first conduit, at least one flow hole, and the second conduit are configured as a flow path. Therefore, the gas is prevented from being brought out from the tank by the second conduit and entering the liquid-cooling pump.

Certain exemplary embodiments can provide a system, machine, device, and/or manufacture that is configured for operably releasing condensate from a condensate producing system to a drain without allowing a substantial quantity of air to enter the condensate producing system from the drain or a substantial quantity of air to exit the condensate producing system to the drain.
