Abstract: The present disclosure belongs to the technical field of heat exchangers, and provides a heat exchanger based on a Gyroid/Diamond (GD-type) hybrid minimal surface-based disturbance structure. The heat exchanger includes a core, headers, and flanges. The core includes a cold fluid channel and a hot fluid channel, the cold fluid channel and the hot fluid channel are separated by a parting sheet. An inlet and an outlet of the cold fluid channel are separated from an inlet and an outlet of the hot fluid channel by sealing bars. A GD-type hybrid minimal surface-based disturbance structure is inserted into the hot fluid channel. A cold fluid and a hot fluid are distributed in a cross-flow manner.

Abstract: A heat exchanger is disclosed having a tube bundle, intended to internally receive a first fluid, and a shell with an inlet opening at a first end. The shell allows an internal circulation of a second fluid and is arranged to surround the tube bundle. An inner casing to the shell circumscribes the bundle within a heat exchange chamber so that between the casing and the shell an annular region extending in a continuous way along the length of the bundle is defined. The annular region is in fluid communication with the exchange chamber through an outflow opening obtained at a second end of the inner casing where the latter has a rear wall facing an opening of the shell to outlet the second fluid from the heat exchanger. The inlet and outlet openings are in fluid communication by means of the annular region.

Abstract: The purpose of the present invention is to provide a tube assembly for a tubular heat exchanger and a tubular heat exchanger comprising the same, the tube assembly for a tubular heat exchanger being capable of enhancing efficiency in heat exchange between a heat medium and a combustion gas and also preventing high-temperature oxidation and the burn-out of a turbulator caused by the combustion heat of the combustion gas and preventing the deformation or damage of a tube which may occur in an environment with a high water pressure, thereby improving the durability thereof. The tube assembly for a tubular heat exchanger of the present invention, for achieving the purpose, comprises: a tube which is formed in a flat shape and enables a combustion gas generated in a combustion chamber to flow along the inside thereof and exchange heat with a heat medium which flows outside thereof; and a turbulator which is coupled to the inside of the tube and induces the generation of turbulence in the flow of the combustion gas.

Abstract: A heat exchanger for cooling a flow of media, comprising a plurality of pipes. The pipes are each received in a respective pipe base at the ends, and the pipes are received in a housing between the two pipe bases, the housing being connected to the pipe bases in a fluid-tight manner. A coolant channel is formed by a shaped region oriented outwards along an outer wall which delimits the housing. The coolant channel has an opening oriented in the direction of the inner volume of the housing, and the coolant channel is in fluidic communication with the inner volume of the housing via the opening. The opening is at least partly covered by a panel, and the panel is arranged on the housing outer wall surface oriented inwards, the outer wall having the coolant channel. A gap is formed between an edge, which delimits the opening, and the panel.

Abstract: Provided is an evaporator capable of, in a centrifugal chiller using a low pressure refrigerant used at a maximum pressure of less than 0.2 MPaG, preventing dry-out of a group of heat transfer pipes in an evaporator to increase heat transfer performance and to suppress reduced efficiency due to carryover of the low pressure refrigerant in a liquid phase to a turbo compressor side and a centrifugal chiller provided with same. An evaporator (7) comprises a pressure container (21) into which a refrigerant is compressed and introduced, a refrigerant inlet (22) provided on a lower portion of the pressure container, a refrigerant outlet (23) provided on an upper portion of the pressure container, a group of heat transfer pipes (25) that exchange heat with the refrigerant through the interior of the pressure container and a tabular refrigerant distribution plate (26) installed between the refrigerant inlet and the group of heat transfer pipes and in which refrigerant flow holes (26a) are drilled. The surface ratio of the refrigerant flow holes per unit area on the refrigerant distribution plate in an area (A1) corresponding to a position near the upstream side of the group of heat transfer pipes is greater than that in another area (A2).

Abstract: A device and method for enhancing the flow of coolant through an EGR cooler, are described. The device includes a housing or tank having an interior space with a fluid inlet for receiving coolant and a fluid outlet for releasing coolant from the interior space. A series of angled baffles in a parallel arrangement are positioned within the interior of the housing from the fluid inlet to the fluid outlet. The baffles extend into a flow path of the coolant redirecting a portion of the flow path above and below the baffles as the coolant passes through the housing. A plurality of tubes or conduit are positioned adjacent the baffles, defining an exhaust gas flow pathway through the housing.

Abstract: A stripping column installation especially for separating starting materials with a high boiling point difference comprises a stripping column having a withdrawal plate and a column sump, and a circulating boiler connected with the stripping column and having a pipe bundle through which a sump product from the stripping column flows. The circulating boiler has an upper plate and a separating wall which separates a space above the upper plate into two chambers. One of the chambers has a connection for receiving the sump product from the stripping column, while the other of the chambers has a connection for discharging the sump product after heating in the boiler. The circulating boiler is located relative to the stripping column so that a height difference is produced between a liquid level on the withdrawal plate of the stripping column and the upper plate of the circulating boiler, the height difference having a value selected so that a total pressure of a liquid column at each point of a first portion of a pipe path in the circulating boiler lies above the vapor pressure of the sump product to be heated.
