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 multi-manifold connector is provided. The multi-manifold connector includes a base, a hot water connector, and a cold water connector, where the hot water connector and the cold water connector are arranged on the base; the hot water connector is provided with a water inlet; the cold water connector is provided with a water outlet; a bottom of the base is provided with multiple first water pipes and multiple second water pipes; the multiple first water pipes run through the base and are communicated with the hot water connector; and the multiple second water pipes run through the base and are communicated with the cold water connector.

The present invention is a cross-flow evaporator adapted to generate vapor from the heat of the exhaust gases from an internal combustion engine. The evaporator is constituted, among other elements, by two plates spaced from one another which contain chambers. The heat exchange tubes alternately communicate the chambers of both plates, establishing a specific path for the fluid intended to change phase. The tubes extending between the chambers of the two plates are arranged transverse to the flow of the hot gas.

This evaporator is suitable for heat recovery systems using a Rankine cycle, making use of the heat from the exhaust gases.

The invention is characterized by a special configuration of the chambers by means of caps that allow the evacuation-of the gases generated during a brazing welding in the manufacturing process.

Provided are heat exchangers for internal combustion engines wherein a first fluid, preferably a hot gas, gives off its heat to a second fluid, preferably a coolant liquid. The presently disclosed heat exchangers include caps that limit the heat exchange capacity of the exchanger without causing differential expansions between elements or parts of these elements that may damage the device or reduce its service life due to thermal fatigue. A device of the presently disclosed subject matter can be sized for the engine having a higher rated power, and the same heat exchanger, can be adapted for operating with engines having a lower rated power without the velocity of the gas to be cooled being reduced, thereby preventing the accumulation of particles therein or fouling.

The present invention relates to a composite heat exchanger for an electric vehicle. The objective of the present invention is to provide an integrated composite heat exchanger that allows a plurality of heat exchange media to be distributed in each area, and to provide a composite heat exchanger for an electric vehicle that obtains effects, by means of integration, such as reducing the number of components and the number of processes, improving refrigerant flow characteristics, and improving cooling efficiency, and in addition, the problem of concentration of thermal stress caused by the integration of the heat exchanger is resolved by means of improving the shape of the area boundary.

A heat exchanger includes tubes arranged side by side, and a tank connected to ends of the tubes. The heat exchanger performs heat exchange between a first fluid flowing inside the tubes and a second fluid flowing outside the tubes. The heat exchanger includes a closing member disposed inside the tank and partially closing an opening provided at an end of a predetermined tube that is at least one of the tubes. The predetermined tube has a protrusion formed at the end of the predetermined tube. The closing member has an avoiding structure that avoids interference between the protrusion and the closing member.

Disclosed is a heat exchanger. An end cover is assembled and fixed to a port of a first header in a lengthwise direction or a port of a second header in a lengthwise direction, and the end cover includes a body and a first opening formed in the body. The body includes a second cavity and a first recess. The first recess includes a first bottom wall close to the first opening, the first bottom wall is provided with a third opening, the third opening is in communication with the first opening and the second cavity, and the first opening is farther away from an inner cavity of the first header or an inner cavity of the second header than the second cavity. The open area of the first recess is larger than that of the third opening.

A method for producing a latent heat accumulator may include filling a can body with a phase-change material in the liquid or solid aggregate state, and closing the can body filled with said solid or liquid phase-change material by flanging such that fluid cannot pass through.

A replacement tube plug for sealing the threaded junction between a tube plug and a bore in a plugsheet, the tube plug including a body part having proximal and distal ends, an outer threaded surface, a central bore open at the proximal end and at least one branch bore extending from and in fluid communication with the central bore and extending radially to the outer surface of the body part, and a method for delivering fluid sealant via the central and branches to the threaded junction of the tube plug and the plugsheet.

A solar panel comprising a plurality of elongated and flat pipe elements having a first end, a second end and at least one longitudinal and through pipe channel for a heat carrying liquid, wherein the pipe channels are arranged with a height (H) up to 10 mm. the pipe elements are connected to opposite and elongated edge elements. The edge elements are arranged with a longitudinal channel for the heat carrying liquid, wherein the channels in the edge elements are connected to the pipe channels and extend in a direction perpendicular to the pipe channels. The pipe elements are formed with an aperture on opposite sides of at least one pipe channel, and stop devices are connected to the edge elements at selected apertures and extend into the channels of the edge elements to block the channels and guide the heat carrying liquid between the pipe channels.
