A heat exchanger system includes a core-in-shell heat exchanger and a liquid/gas separator. The liquid/gas separator is configured to receive a liquid/gas mixture and to separate the gas from the liquid. 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.

In a header plateless type heat exchanger, to suppress temperature rise at an apical portion of a tube into which exhaust gas at high temperatures or the like flows, to thereby improve durability. A recessed groove portion 4c recessed inward with narrow width is formed on outer face side of each of a pair of plates, in parallel to a swelling portion 4 and in the approximately same length.

The present disclosure relates to the technical field of heat exchange devices, and in particular, to a plate, a plate assembly and a heat exchanger. The plate comprises a plate body and a first through hole and a second through hole provided on the plate body; the plate body forms a pipe segment around the first through hole, and the second through hole is arranged close to the outer periphery of the pipe segment.

A heat exchanger having a stack of multiple plates which are parallel to one another and to a longitudinal direction, and stacked spaced apart from one another so as to define, between one another, a first series of passages for the flow of at least a first fluid in an overall flow direction parallel to the longitudinal direction, each passage being delimited by closure bars disposed between the plates. A filtering device is arranged in at least one passage of the first series, the filtering device extending for the one part between two adjacent plates defining the passage and for the other part between two of the closure bars delimiting the passage, the filtering device having a metal sheet material chosen from among a metal fabric, a nonwoven of metal fibres, a sintered metal powder or sintered metal fibres, a metal foam, or a microperforated plate.

A tube type heat exchanger includes a core includes multiple tubes, a header plate defining an array of apertures in which said tubes are received, and a coolant jacket arranged about said core. The header plate includes a body defining a central region and an edge region circumferential to said central region. The central region defines said array of apertures. The edge region includes a flange. The header plate is connected to the coolant jacket via first and second contact areas between the header plate and the coolant jacket. The flange is outboard of the coolant jacket. The first contact area is between the flange and the coolant jacket; and the second contact area is inboard of the first contact area.

The disclosure relates to a heat exchanger. The heat exchanger includes a shell and heat exchange tube bundles located in the shell, the shell has an inlet and an outlet, and a refrigerant flows in through the inlet, exchanges heat with a fluid in the heat exchange tube bundles, and then flows out from the outlet, and the outlet is provided with an extension section that extends into an interior of the shell and has a receiving portion configured to receive at least a part of a liquid in the refrigerant flowing toward the outlet after heat exchange. The disclosure is easy to manufacture, install and maintain, and has a low cost. By optimizing the structure of an outlet pipeline of the heat exchanger, the influence of liquid carryover can be effectively controlled, and the overall performance, safety and reliability of the system can be enhanced.

A heat transfer plate comprises a first end portion, a second end portion and a center portion arranged in succession along a longitudinal center axis of the plate. The center portion comprises a heat transfer area provided with a heat transfer pattern comprising support ridges and support valleys longitudinally extending parallel to the longitudinal center axis of the plate. The support ridges and support valleys are alternately arranged along a number of separated imaginary longitudinal straight lines extending parallel to the longitudinal center axis of the plate and along a number of separated imaginary transverse straight lines extending perpendicular to the longitudinal center axis of the plate. The heat transfer pattern further comprises turbulence ridges and turbulence valleys. At least a plurality of the turbulence ridges and turbulence valleys along at least a center portion of their longitudinal extension extend inclined relative to the transverse imaginary straight lines.

A method for manufacturing a roll-bond heat exchanger has steps of: (1) A preparing step: preparing an in-process roll-bond plate that has a main plate with a bulged structure, and a degassing portion with a tube; (2) A degassing step: removing air from the bulged structure through the tube; (3) A filling step: filling refrigerant into the bulged structure; (4) A pressing step: pressing the bulged structure flat to form a pressed portion; (5) A cutting step: cutting the degassing portion to form a cut portion on the main plate; and (6) A sealing step: welding the cut portion. The main plate and the degassing portion are integrally formed as a single part and the degassing portion is able to be directly connected with the vacuum filling machine. Accordingly, processing steps and manpower for manufacturing the roll-bond heat exchanger are reduced.
