The heat exchange plate having a heat exchange portion and a port portion; fluids having different temperatures exchange heat with each other by means of the heat exchange portion; an opening used as the port of the heat exchanger is formed in the port portion. The heat exchange plate includes a first side and a second side in a direction perprendicular to the heat exchange plate; the port portion is provided with a contact porition that is in contact with the port portion of another heat exchange plate at the first side, and a protrusion protruding towards the second side relative to the contact portion. The heat exchange plate and the plate-type heat exchanger of the embodiments of the present invention can, for example, improve the quality of the port portion of the heat exchange plate of the heat exchanger.

A heat exchanger for a gas turbine engine comprising a compressor, a combustor and a turbine. The heat exchanger comprising alternating hot and cold channels. Compressed air from the compressor flows through the cold channels and exhaust gas from the turbine flows through the hot channels. Each cold channel comprises first and second opposing surfaces conveying compressed air along a first path. Each cold channel comprises rows of vortex generators and pin fins extending from the first or second surfaces along the first path. The rows extend substantially perpendicular to the first path. Each hot channel is defined by a first and second opposing surfaces conveying exhaust gas along a second path substantially perpendicular to the first path. Each hot channel comprises rows of vortex generators and pin fins extending from the first or second surfaces along the second path. The rows extend substantially perpendicularly to the second path.

In order to provide a cold storage medium container that can be smoothly and reliably filled with a cold storage medium to thereby increase productivity. In a cold storage medium container 5, a body of the container 5 constituted of a pair of container members 10 and 12, and the body has an inner fin 11 therein and is filled with the cold storage medium through a cold storage medium filling opening 20 at an end of the body therein. Furthermore, in the cold storage medium container, an engagement portion 13 projects toward inside of the body to engage a part of a corrugated end surface at each end of the inner fin 11, to thereby position the inner fin 11 in the body, and a gap is disposed between the end surface at each end of the positioned inner fin 11 and an inner wall of the body.

A rapid warm-up heat exchanger for heating a fluid using exhaust gas includes multiple plate pairs that are joined by braze joints to form a stack. A fluid inlet manifold and a fluid manifold extend through the stack, and each one of the plate pairs defines a tortuous flow path for the fluid that extends between the fluid inlet and fluid outlet manifolds. A housing surrounds the stack, and together the housing and the stack define an exhaust flow path in spaces provided between adjacent plate pairs. A valve element can be provided within the housing in order to selectively direct exhaust flow through the exhaust flow path.

The disclosure provides a heat exchanger and an, air conditioner with the heat exchanger. A heat exchange assembly includes a first channel and a second channel which are used for allowing a refrigerant to pass through, a communication portion communicated with the first channel and the second channel, and a plurality of protrusions.

Disclosed are a heat exchange plate (10) and a plate-type heat exchanger using the heat exchange plate (10). The heat exchange plate (10) comprises: a body; pits and/or protrusions (3), arranged on the surface of the body in predetermined patterns; and a plurality of adjusting portions (1, 2), wherein four quadrangular adjusting portions (1, 2) are arranged at the periphery of each pit and/or protrusion (3), then a basic heat transfer unit (4) is formed by each pit and/or protrusion (3) and the adjusting portions (1, 2) at the periphery thereof, and the adjusting portions (1, 2) in each basic heat transfer unit (4) are arranged to be provided with relatively large gaps in a main flow direction (D 1) of fluid on the heat exchange plate (10) and are arranged to be provided with relatively small gaps in an auxiliary flow direction (D2) of the fluid on the heat exchange plate (10).

A heat exchanger is provided. The heat exchanger is formed of a spiral wound flow body (70) having a plurality of passages (76) ending therethrough for passage of a first fluid. The flow body is positioned within a housing (42) and a cross-flow of a second fluid passes between or across successive layers of the spiral wound flow body. The intermixing of the thermal energy of the cross-flowing second fluid and the first fluid provide improved heat exchange.
