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 heat exchanger for a motor vehicle includes heat exchange bundle with a plurality of stacked tubes inside which a first heat-transfer fluid circulates, and an end flange arranged on each side of the stack of tubes which brazed to the heat exchange bundle. The end flanges include a flat body with a first surface that faces an aerodynamic element and a second surface, the brazing surface, opposite to the first surface and brazed to the heat exchange bundle. Attachment tabs receive the aerodynamic element and are arranged on the sides of the flat body, the attachment tabs projecting in the opposite direction to the heat exchange bundle. At least one extension of the flat body extends in the same general plane as the flat body and is arranged between a pair of attachment tabs on a same side of the flat body.

A heat exchanger for boilers, in particular for condensing boilers. The heat exchanger having a set of heat exchanging plates inside which the water to be heated flows and outside which the combustion products coming from a burner pass. The heat exchanger has plates coupled to diaphragms for closing openings present on the plates; each plate having at least two levels of respective channels for the water flow to be heated. Hydraulic connections in series between the channels can be provided on the layer closest to a burner.

Methods, plate elements and heat/enthalpy exchangers. a) perforating an unformed plate element with defined outer dimensions in any desired area and in any desired dimension; b) covering at least one side of the unformed plate element with a thin polymer film with latent energy exchange characteristics and; c) forming the plate element into a desired shape and a pattern of corrugations and/or embossing. The operations b) and c) may be performed in a different order. For instance, when the plate element is made out of plastic, b) may be performed before c) whereas, when the plate element is made out of aluminum (or plastic), c) may be performed before b). Operations a) and/or b) and/or c) may also, in certain embodiments, be combined.

A heat exchanger for allowing heat to be exchanged between a first fluid and at least one other fluid comprises: a core comprising: at least one flow path; a manifold in communication with the at least one flow path; wherein the manifold comprises a void formed in the core; and the manifold comprises end caps, wherein at least one of the end caps is a non-flat end cap.

A forging device produces a forged product in which a protrusion is formed on a base plate. The forging device has a die with a molding hole and a punch to be driven into the molding hole. A protrusion molding cavity is formed in a bottom surface of the molding hole or a tip end surface of the punch in the die. A base plate molding portion is formed between the tip end surface of the punch and the bottom surface of the molding hole. A burr molding portion is formed between the tip end portion outer peripheral side surface of the punch and the inner peripheral side surface of the molding hole. The inner peripheral side surface of the molding hole is formed by an inclined surface that approaches an axis as it advances toward the pressing direction of the punch.

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 diffuser plate for a thermal transfer device can include a body having a number of first apertures and a second aperture that traverse therethrough, where the first apertures are asymmetrically arranged with respect to the second aperture. The first apertures can have a first shape and a first size, and where the first apertures are configured to receive a plurality of tubes. The second aperture has a second size, where the second size is larger than the first size.

A plate-type heat transport device is provided. The plate-type heat transport device includes a metal plate having a meandering shape flow passage. The flow passage includes multiple linear channels and return channels. The linear channels extends in parallel to each other from a first end of the metal plate to a second end of the metal plate. The return channels are located in the first and second ends of the metal plate to allow the linear channels to communicate with each other. A first area of the metal plate associated with the linear channels is thinner than a second area of the metal plate associated with the return channels. The flow passage of the metal plate contains a hydraulic fluid.
