The invention relates to a heat exchanger plate (10) of a heat exchanger, the heat exchanger plate (10) comprising two faces (12, 13) extending between two lateral edges and two longitudinal edges (15) of said heat exchanger plate (10). The heat exchanger plate (10) comprises at least an opening (16) extending from a first face (12) to a second face (13) of the heat exchanger plate (10). The opening (16) is delimited by a collar (17) that is arranged around the opening (16). The heat exchanger plate (10) comprises at least a dimple (18) protruding above at least one of the faces (12, 13). Said dimple (18) comprises at least a flat area (19) and a slopped area (20), said slopped area (20) being interposed between the collar (17) and the flat area (19).

A vapor chamber with a support structure and its manufacturing method are provided. The vapor chamber with the support structure includes a first plate, a second plate spaced apart from the first plate, and multiple support elements fixed between the first and second plates. On an outer surface of any of the first plate or the second plate, laser welding is performed on positions corresponding to the support elements so as to join the support elements to the first and second plates and to form weld ports on the outer surface of any of the plates. The invention solves the problem of fixing the support structure inside the thin vapor chamber, and therefore mass production can be realized.

A loop-type heat pipe includes an evaporator configured to vaporize an operating fluid, a condenser configured to liquefy the operating fluid, a liquid pipe configured to interconnect the evaporator and the condenser, a steam pipe configured to interconnect the evaporator and the condenser and to form a loop together with the liquid pipe, a porous body provided in the liquid pipe and configured to retain therein the liquid operating fluid, and a solid columnar support provided in the liquid pipe and configured to guide the operating fluid liquefied by the condenser to the porous body. At least one first groove is formed at a side surface of the columnar support.

In a featured embodiment, a heat exchanger includes a plate including a plate portion having outer walls. A plurality of internal passages extend between end portions. A ratio between an outer wall cross-sectional thickness at one of the end portions and a cross-sectional wall thickness of the outer wall within the plate portion is greater than 2.5 and no more than 10. An inlet manifold is attached to the inlet end. An outlet manifold is attached to the outlet end.

A radiator includes a radiator frame, an array of tube assemblies each including a coolant tube and a tube clip supported in the radiator frame, and a lateral bump stop fitted between the array of tube assemblies and the radiator frame. The lateral bump stop includes cushions arranged in a staggered cushion pattern complementary to a staggered packing pattern of the tube assemblies with each of the cushions in contact with the tube clip of one of the tube assemblies.

An evaporator comprises: a housing with a refrigerant inlet and a refrigerant outlet; heat transfer tubes that are contained in the housing, in which chilled water for heat exchange with refrigerant inside the housing flows; at least one distribution tray that is placed apart from the heat transfer tubes and has a plurality of holes for distributing refrigerant over the underlying heat transfer tubes; a vapor-liquid separator that is placed apart from the bottom of the distribution tray and separates an introduced refrigerant into a vapor refrigerant and a liquid refrigerant; and a pair of support frames that are fixed to either side of the width direction of the housing, wherein the vapor-liquid separator comprises: a chamber that has an inlet port communicating with the refrigerant inlet, a vapor refrigerant exit communicating with the refrigerant outlet, and a plurality of holes formed in the bottom to distribute the liquid refrigerant to the distribution tray; and a plurality of side arms that are formed on either side of the chamber and arranged in the length direction of the chamber and supported by the support frames. Through the present disclosure, it is possible to keep the vapor-liquid separator horizontal and stable and achieve stable heat exchange performance.

A heat exchanger includes a plurality of first and second fluid passages. The first fluid passages are defined by a pair of opposing first fluid passage walls and a plurality of first fluid diverters disposed between the first fluid passages walls. The second fluid passages are defined by a pair of opposing second fluid passage walls and a plurality of second fluid diverters disposed between the second fluid passage walls. The second fluid diverters include a body portion and a leading edge portion. The first fluid passage walls form a first fluid leading edge that extends upstream of the leading edge portion of the second fluid diverters. The second fluid passages extend in a direction perpendicular to the direction of the first fluid passages.

A heat transferring module adapted to contact a heating element is provided. The heat transferring module includes a first plate, a second plate and a working fluid. The second plate is connected to the first plate to form a cavity therewith, and the cavity extends along an extension direction of a reference plane. The working fluid is located in the cavity, wherein the cavity is a first area, and a portion of the first plate or a portion of the second plate extending beyond the cavity is a second area. The first area transfers heat by heat convection, and the second area transfers heat by heat conduction.

A vapor chamber includes a first base plate (12), a second base plate (13), and a capillary structure (15). The first base plate (12) and the second base plate (13) are disposed in a stacked manner and fastened to each other, and together form a cavity (11). The capillary structure is disposed on an inner wall of the cavity (11) and a surface of at least one support pillar (120) between the first base plate (12) and the second base plate (13), and the capillary structure (15) is configured to provide capillary force for returning liquid to a working medium. A reinforcement table (127) located in the cavity (11) is disposed between the first base plate (12) and the second base plate (13).

A method can include additively manufacturing a heat exchanger core having one or more fluid channels using a first additive manufacturing process and a first material. The method can also include additively manufacturing a support structure around the heat exchanger core using a second additive manufacturing process different from the first additive manufacturing process and a second material different from the first material after additively manufacturing the heat exchanger core.
