A heat exchanger is provided according to the present application, which includes a core body. The core body includes a first sheet and a second sheet that are arranged in a stacked manner. The core body is provided with a first fluid channel and a second fluid channel that are isolated from one another. The first fluid channel includes a first pore channel and a second pore channel. The core body further includes a first blocking part. The first pore channel includes a first sub-pore channel and a second sub-pore channel. The heat exchanger further includes a first connection port and a second connection port that are located on the same side of the core body in the thickness direction thereof.

A heat exchanger (4) has fluid flow channels (6) with at least one heat exchanging surface (10) which has an undulating surface section for which the surface profile varies along a predetermined direction such that at a first edge (E1) the surface profile follows a first transverse wave (20), at a second edge (E)2 the surface profile follows a second transverse wave (22) and at an intermediate point I between the edges the surface profile follows a third transverse wave (24). The third transverse wave (24) has a different phase, frequency or amplitude to the first and second transverse waves so that chevron-shaped ridges and valleys are formed. This improves the mixing of fluid passing through the channel and hence the heat exchange efficiency.

A heat exchanger includes a main body provided with first flow paths through which a first fluid flows and second flow paths through which a second fluid flows. Each first flow path includes an integrated part, a buffer part, and a divided part arranged in this order from an inlet of the main body. The integrated part includes a first flow path space defined by a peripheral wall including a pair of mutually facing partition walls. The buffer part includes a deformed flow path space formed by deforming the first flow path space such that first displacement parts or each of multiple pairs of first displacement parts provided at intervals on the pair of partition walls approach each other. The divided part includes multiple divided flow path spaces formed by dividing the first flow path space by connecting the first displacement parts of each pair to each other.

The purpose of the present invention is to provide a plate-type heat exchanger in which the formation of burrs and chips during fin processing may be eliminated by eliminating fin processing work for stacking and bonding fins and plates. In order to achieve the above purpose, a plate-type heat exchanger according to the present invention is characterized by comprising: plates which include an inlet formed on one side in the longitudinal direction, an outlet formed on the other side in the longitudinal direction, and a flow surface formed between the inlet and the outlet; and a fin part which is inserted into a plate part formed by bonding a pair of the plates and rests on the flow surface. The plates include a fin part movement preventing means to ensure that one end of the fin part in the longitudinal direction is spaced a certain distance from the inlet and the other end of the fin part in the longitudinal direction is spaced a certain distance from the outlet such that the fin part rests only on the flow surface.

A heat exchanger for an internal combustion engine transfers heat between fluids and includes a housing having a housing wall and a housing interior bordered at least in regions by the housing wall. The housing interior has a fluid inlet region for introducing a first fluid of the fluids into the housing interior and a fluid outlet region for discharging the first fluid out of the housing interior. The heat exchanger has at least two partition walls, which are at least substantially accommodated in the housing interior and connected to the housing wall of the housing at at least one connection region. The partition walls border at least regions of a fluid receiving chamber, through which a second fluid of the fluids can flow, in order to separate the fluids from one another. The partition walls are connected to one another at least at a joining region associated with the fluid inlet region and adjacent to the fluid receiving chamber in a main fluid flow direction of the first fluid. The partition walls also have a deformation, at least in a joining sub-region of the joining region spaced apart from the connection region, which is provided to at least reduce mechanical tension in the at least one connection region due to a temperature-dependent change in length of the joining region.

A heat exchange assembly, which comprises a first heat exchange part, a bridge, and a second heat exchange part, wherein the bridge is at least partially located between the first heat exchange part and the second heat exchange part; the bridge comprises two holes or grooves that face the first heat exchange part and may communicate with the first heat exchange part; the bridge comprises two holes or grooves that face the second heat exchange part and may communicate with the second heat exchange part; the bridge further comprises a third interface part provided with a third interface; and the bridge has a hole and/or groove that is in communication with the third interface. Fluid communication between the two heat exchange parts may be achieved relatively conveniently by means of the bridge, and different system requirements may be achieved by means of changing the structure of the bridge, so that a system pipeline is simple, the arrangement of pipelines can be minimized between the interfaces, and the system connection is simple and convenient.

A heat exchanger has a plurality of plates having opposed surfaces and side walls extending beyond the opposed surfaces to a height (h); and a fin pack extending from one opposed surface toward an opposed surface of an adjacent plate, and having a fin height (f), wherein the fin height (f) is equal to or less than the height (h). The plates can be stacked to form a heat exchanger assembly with a gap between adjacent fin packs.

The present invention relates to a plate element (2) having a first heat transfer plate (10) and a second heat transfer plate (20), the first heat transfer plate (10) and the second heat transfer plate (20) being connected to each other to form the plate element (2). Each of the first heat transfer plate (10) and the second heat transfer plate (20) is formed of a plate body with a main part with a heat exchanging portion (40) formed with a surface pattern (45). The first heat transfer plate (10) is formed with a first set of openings (3a, 3d) in first extension sections (50) reaching out from the main part of the plate body, and the second heat transfer plate (20) is formed with a second set of openings (3b, 3c) in second extension sections (50) reaching out from the main part of the plate body. The first extension sections (50) of the first heat transfer plate (10) and the second extension sections (50) of the second heat transfer plate (20) are positioned such that the first set of openings (3a, 3d) and the second set of openings (3b, 3c) are not overlapping.

The plurality of stacked plates may each include a first opening and at least two second openings arranged around the first opening. The heat exchanger may also include a plurality of webs each arranged between two adjacent second openings. The plurality of webs may form the support structure.

The inlet and outlet of water of the first stage (E1) are respectively connected to the outlet of the water radiator, by means of a cooling water circuit internal to the engine (M), and to the water inlet of the second stage (E2). The water outlet of the second stage (E2) is connected to the inlet of a water radiator, and the inlet and outlet of oil in the second stage (E2) are connected in series to a lubricant oil circuit internal to the engine (M).
