A heat exchanger with a tube bundle wound in a helical manner about a longitudinal axis. The tube bundle includes at least two tube sections which are placed beside each other in the direction of the longitudinal axis. The tube sections each include a helically wound tube with has an internal cross-section which is constant over the helical winding thereof.

A structure for the end of pressure vessels, most applicably plate heat exchangers, for reducing the effects of movement changes and vibrations caused by variations in internal pressure and temperature. The end is made up of a heat transfer plate and an end part in such a way that the end part is connected by welding to the shell of the outer surface of the heat exchanger stack, forming an enclosed chamber on the end of the heat exchanger, into which chamber higher pressure than the external pressure level is brought and/or generated. The higher pressure receives and dampens, via a heat transfer plate, vibration and pressure shocks harmful to the heat exchanger structure in the medium circuits of the heat exchanger.

A device for use in a refrigeration or heat pump system. A device includes an outer casing which includes a longitudinal cylindrical shell and end plates arranged at both ends of the shell, and at least three units of the refrigeration or heat pump system arranged inside the same common outer casing, which units are selected from the group consisting of an evaporator, a superheater, an economizer, a condenser, a desuperheater, a sub-cooler and an oil cooler.

A heat exchanger may include a tubular housing, a flange ring, two bases, and heat exchanger tubes that run through the housing and are each held in the bases at a longitudinal end side. A first flow channel may be formed in the heat exchanger tubes, and a second flow channel may be formed between the heat exchanger tubes and the housing. The housing may be formed from two one-piece and pot-shaped housing parts. Each housing part may have a housing section, a flange ring section, and a base. The two housing parts may be connectable to one another via the two flange ring sections.

A cooling device has a heat receiving unit that has a space therein, liquid phase piping that supplies liquid phase refrigerant to the heat receiving unit, gas phase piping that discharges gas phase refrigerant from the heat receiving unit, and spacers that are disposed inside the heat receiving unit. The spacers have a higher specific gravity than the liquid phase refrigerant. The spacers have a shape allowing movement along the bottom face of the heat receiving unit. When the heat receiving unit tilts, the spacers move to the low side of the heat receiving unit. The spacers gather on the bottom face of the heat receiving unit on the low side. The liquid phase refrigerant spreads to the high side of the heat receiving unit by an amount equivalent to the volume removed due to the spacers, and uniform cooling can be performed.

An inline heater includes a heater core that includes a heat spreader assembly comprising a tubular heat spreader that extends axially along a longitudinal axis and that comprises an external surface. The heat spreader assembly includes a fluid inlet and a fluid outlet. At least one conduit extends helically about the longitudinal axis of the heat spreader between the fluid inlet and the fluid outlet to define a fluid heating flow path that fluidically connects the fluid inlet and the fluid outlet. The heat spreader assembly further comprising an electrically operated heating element for heating the heat spreader.

An example refrigeration system includes an indoor fluid loop, an outdoor fluid loop, and a heat exchanger assembly. The indoor fluid loop circulates a first working fluid. The outdoor fluid loop circulates a second working fluid that is different from the first working fluid and is separated from the indoor fluid loop by a wall of a structure. The heat exchanger assembly is mounted within the wall of the structure. The heat exchanger assembly includes a heat exchanger and a housing, where the heat exchanger is disposed within an internal space defined by the housing. The housing supports the heat exchanger within the internal space and is mounted to a structure of the wall.

An evaporator (1) for vaporizing a substance into its gaseous form, which comprises a cylindrical outer shell (2) and a plate pack (4) arranged inside the cylindrical shell in its lower part and a droplet separator (9) arranged above the plate pack. A recirculation of a substance to be vaporized is carried out by using flow guides (10a, 10b) arranged tightly between the plate pack and the outer shell and by an ejector pipe (13) arrangement comprising a collection pipe (11) arranged inside the outer shell.

A can-type heat exchanger may include a housing having a space therein, integrally formed with a mounting portion, and a first inlet and a first outlet; a partition wall integrally formed to the housing, separating the space and the inside of the mounting portion, and forming a bypass passageway inside of the housing; a heat radiating unit inserted into the space, provided with connecting lines alternately formed by stacking a plurality of plates; a cover cap mounted at opened one surface of the housing, and a second inlet and a second outlet for communicating a second connecting line of the connecting lines; and a valve unit mounted at the first inlet formed in the mounting portion and penetrating the partition wall in the mounting portion, selectively opening and closing the space or the bypass passageway separated by the partition wall using linear displacement.

The present invention relates to a heat exchanger for a motor vehicle provided on the front surface of an engine room of the vehicle, and, more particularly, to a heat exchanger for a motor vehicle including a sealing member provided on the circumference of the heat exchanger in order to prevent driving-induced wind from leaking to the outside of the heat exchanger without passing through the heat exchanger.
