A device for closing at least one inner tube in a tubular heat exchanger. The device comprises a main body provided with inner tube through holes and at least one plug configured to be inserted into the at least one inner tube.

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.

A liquid receiver is composed of a tubular base member having open upper and lower ends, a tubular tank member having a closed upper end and an open lower end and joined to the base member, and a plug fitted into the base member. A female screw is provided on the inner circumferential surface of the base member, and refrigerant inflow and outflow holes are formed in a portion of the base member above the female screw such that the former is located above the latter. A male screw to be screwed into the female screw is provided on the outer circumferential surface of the plug to be located below the refrigerant outflow hole. Sealing is established between a portion of the inner circumferential surface of the base member located below the female screw and a portion of the outer circumferential surface of the plug located below the male screw.

A heat exchanger has a rectangular-shaped core having a plurality of fluid passages extending in a width direction and air fins interleaved between said fluid passages. The heat exchanger has tanks that define fluid manifolds located at opposite ends of the core and fluidly connected by the plurality of fluid passages between the tanks. The tanks each include an extruded tank section with open ends and end caps that enclose the ends of the extruded tank section. The tanks are assembled and attached to the core such that each of the end caps is located at each of four corners of the rectangular-shaped core.

The present invention relates to a tube with a reservoir of phase-change material (1) comprising: two flow plates (3) configured to be assembled with one another, at least one reservoir plate (5) being configured to be assembled onto an external face of one of the two flow plates (3) so as to form housings,
said tube with a reservoir of phase-change material (1) further comprising a filling duct (200), said filling duct (200) being formed, on the one hand, by a filling spout (201) of the reservoir plate (5) towards the outside and, on the other hand, by the external face of one of the two flow plates (3), said filling duct (200) further comprising a plug (210), said filling duct (200) and said plug (210) being contained within a volume of width smaller than or equal to the width of the tube with a reservoir of phase-change material (1) and of height less than or equal to the height of the housings.

A condenser having a receiver for storing liquid refrigerant, the condenser having a heat exchanger block with at least one manifold and with a tube and fin block, wherein the tubes communicate with the at least one manifold for introducing and releasing refrigerant to or from the heat exchanger block. The receiver is located adjacent to one of the manifolds. The receiver has a tube with at least one open tube end and with at least one disc. The disc is located within the tube at the tube end in order to close the tube end and the disc is fluid tight connected with the tube end by cold metal transfer welding.

An apparatus for cooling liquids comprises an external tank and several internal cooling flasks. The external tank is shaped like a closed tank with a top opening. The internal cooling flasks are designed to be set inside the external tank in such a way that very narrow spaces are formed between the external walls of each cooling flask and the adjacent flasks, thus forming an internal cooling space, in a way that enables the user to pour of hot water into the internal cooling space, and the coolant in the cooling flasks adsorbs the heat of said hot water.

A combination heat exchanger comprises a first heat exchanger assembly and a second heat exchanger assembly. The first heat exchanger assembly includes a first end tank, a second end tank, and a first heat exchanger core including a plurality of first heat exchanger tubes extending longitudinally in a first direction. The second heat exchanger assembly includes a third end tank, a fourth end tank, and a second heat exchanger core including a plurality of second heat exchanger tubes extending longitudinally in the first direction. A first coupling includes a first attachment portion rigidly coupled to the first end tank, a second attachment portion rigidly coupled to the third end tank, and a thermal expansion portion extending between the first attachment portion and the second attachment portion. The first coupling is configured to allow for relative translation between the first end tank and the third end tank in the first direction.

Heat sinks having a mounting surface with a coefficient of thermal expansion matching that of silicon are disclosed. Heat pipes having layered composite or integral composite low coefficient of expansion heat sinks are disclosed that can be mounted directly to silicon semiconductor devices.

A flow control system in an inlet duct to a heat exchanger includes a door having a first end and a second end opposite the first end. The first end rotates about an axis and the second end moves between an open position and a closed position to respectively allow and prevent flow into the heat exchanger. The second end has a rounded configuration. A plurality of mixing elements are downstream of the door. At least one mixing element has a base portion and a distal portion, and the base portion has a base width and the distal portion has a distal width. The base width is wider that the distal width.
