The present application discloses a microchannel flat tube and a microchannel heat exchanger. The microchannel flat tube includes a flat tube body and a row of channels. The row of channels is arranged in the flat tube body along a width direction. The row of channels extends through the flat tube body along a length direction. A cross-section of each channel includes a first width in the width direction and a first height in a thickness direction. The row of channels at least includes a first group of first channels, a second group of second channels and a third group of third channels along the width direction. The first widths of the first channels, the second channels and the third channels decrease at a fixed rate, thereby facilitating the control of the thickness of the microchannel flat tube and improving the heat exchange efficiency of the third channels.

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 plate cooler or heat exchanger includes a channel plate defining first cooling channels on a first side of the channel plate and second cooling channels on a second side of the channel plate opposite to the first side. The first cooling channels are arranged side-by-side in a first direction of coolant flow from a first common inlet to a first outlet. The second cooling channels are arranged side-by-side in a second direction of coolant flow from a second common inlet separate from the first common inlet to a second outlet separate from the first outlet. The second direction of coolant flow is transverse or counter to the first direction of coolant flow.

A cooling device includes: a container in which a refrigerant is sealed; an evaporating part that evaporates the refrigerant in a liquid phase by heat reception inside the container; a condensing part that condenses the refrigerant in a gas phase by heat dissipation inside the container; and a plate-shaped or block-shaped flow path member in which a plurality of flow paths configured to transport the refrigerant in a liquid phase from the condensing part to the evaporating part by surface tension inside the container is formed in parallel.

A counter-flow heat exchanger core includes a first wall defining a longitudinal axis. The first flow path is defined within the first wall. The first flow path includes a primary flow inlet and a primary flow outlet downstream from the primary flow inlet. The heat exchanger core includes at least two hollow vanes circumferentially spaced apart and extending in a radially inward direction from the first wall. Each of the at least two hollow vanes includes a first vane wall and a second vane wall. The heat exchanger core includes a second flow path defined within the at least two hollow vanes between the first vane wall and second vane wall of each of the at least two hollow vanes. The heat exchanger core includes at least one fin extending between two of the at least two circumferentially spaced apart vanes.

A heat exchanger including a first header tank and a second header tank that are disposed to be spaced apart a predetermined distance in a height direction and a core part that is disposed between the first header tank and the second header tank and includes a plurality of tubes and fins, the first header tank including a first header plate, a first tank, and a first partition wall that divides a space formed by a combination of the first header plate and the first tank to form a plurality of flow paths, a manifold including an inflow passage and an outflow passage being connected to an outer side of the first header tank, and the inflow passage and the outflow passage having different sizes to each other, the outflow passage having a larger cross-sectional area than that of the inflow passage.

Pipe arrangement for transporting temperature control media, comprising a base body which is produced by means of blow molding and from which at least a first channel and a second channel are formed, wherein the first channel and the second channel have a first orientation towards one another in a first section and a second orientation towards one another in a second section, wherein the first orientation is different from the second orientation.

Some embodiments of the present disclosure provide a flat tube and a heat exchanger. The flat tube includes a middle tube segment and necking connection segments located at two ends of the middle tube segment, wherein a width of each of the necking connection segments is less than a width of the middle tube segment, a transition connection segment is provided between the each of the necking connection segments and the middle tube segment, and the transition connection segment is provided with a fastening and positioning part.

An intercooler assembly for an intercooler supercharger system comprising a plurality of separate, contiguous intercooler cores, each including a top and a bottom, wherein the tops of the intercooler cores are coplanar and at least two of the bottoms of the intercooler cores are not coplanar.

A heat exchanger includes first and second headers connected to end portions of heat transfer tubes. The second header includes a header pipe defining a flow space that communicates with the heat transfer tubes and, when the heat exchanger acts as an evaporator, allows refrigerant in a two-phase gas-liquid state to pass through the flow space into the heat transfer tubes. A bypass pipe is disposed between an entrance portion and the first header. The entrance portion has an entrance distance L between a connection end portion connected to a refrigerant pipe and a central axis of the bypass pipe. The entrance distance L of the entrance portion satisfies L≥5di, where di is an inner diameter of a flow space of the header pipe on an orthogonal plane orthogonal to a direction of refrigerant flow. The bypass pipe is inserted in the flow space of the entrance portion.
