The invention relates to a shell-and-tube heat exchanger for changing the temperature of a medium, having a plurality of channels of the tubes, an inlet chamber, an outlet chamber, and at least one channel of the shell for a further medium, wherein the medium can be conveyed into the inlet chamber and, from there, through at least a portion of the channels of the tubes into the outlet chamber, and having a closure means arranged on the outlet chamber and designed and adjustable in such a way that outlet openings of each subset of a plurality of different subsets of the channels of the tubes can be closed off. The invention also relates to a method for changing the temperature of a medium by means of a shell-and-tube heat exchanger.

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 liquid receiver of a condenser has a liquid receiver main body and a plug removably fitted thereinto. The liquid receiver main body has a refrigerant inflow hole into which refrigerant flows from a condensation section and a refrigerant outflow hole from which refrigerant flows into a supercooling section. The liquid receiver has a first space formed above the upper end of the plug and communicating with the refrigerant inflow hole and a second space formed below the upper end of the plug and communicating with the refrigerant outflow hole. The plug has a flow passage which is open to the first space and the second space at opposite ends. The first-space-side opening of the flow passage is located below the refrigerant inflow hole. The flow passage has a throttle portion whose cross-sectional area is smaller than a hole area of the refrigerant inflow hole.

An exothermal vaporizer is provided. The exothermal vaporizer has a body including an air and vapor mix port, a fluid inlet port in communication with a reservoir, an air inlet, and a wicking material. A mouthpiece is coupled to the body and a temperature indicating cap is removable from the body. A counter flow design exothermal vaporizer, a modular exothermal vaporizer, and a vaporizer which is adjustable to modulate and/or regulate the flow ratio of dilution air and produced vapor are also disclosed.

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 heat exchanger and an air conditioner comprising the heat exchanger are provided. The heat exchanger includes a gaseous refrigerant heat exchange pipe (6) and a liquid refrigerant heat exchange pipe (7) provided on the same side of the heat exchanger, the heat exchanger further includes a gaseous refrigerant heat exchange branch pipe (2) and a liquid refrigerant heat exchange branch pipe (3). During installation of the heat exchanger and the air conditioner, a pipe exiting direction may be selected according to user demands without bending the pipes, a pipe routing space does not need to be reserved on the back of the whole machine, and installation is facilitated.

A manifold for a heat exchanger includes a first tubular manifold part and a second tubular manifold part. The ends of the first and second manifold parts are connected through a baffle which is arranged to block tubular openings of the ends. The baffle substantially separates the ends of the first and second manifold parts.

A heat exchanger is formed by a plurality of heat exchanger units each including a respective small tank at each end of a core, the units being stacked in a thickness direction of the cores, and oil is supplied to finned tubes constituting the core of each of the units via a header. Each of the tanks has an opening for communicating with the header which opening is at a position on the length of the tank different from that of each of the adjacent tanks.

In a heat exchanger including a header tank which includes a header plate through which end portions of a number of flat tubes placed in parallel are inserted, and a header body fitted to the header plate, the header plate and the header body are temporarily assembled easily and accurately, and joined more accurately by brazing. The header body is formed in a gutter-like shape, and positioned with both ends thereof on an opening side in contact with both ends of a major axis on an opening end surface of each flat tube inserted into the header plate.

A heat dissipation apparatus having a base, a heat dissipater, and a plurality of fin arrays. The base has at least one horizontal portion disposed in the base and at least one vertical portion extending therefrom. At least one of the plurality of fin arrays coupled with the at least one horizontal portion of the heat dissipater and at least one of the plurality of fin arrays coupled with the at least one vertical portion of the heat dissipater.
