A heat exchanger includes a core and a header tank. The header tank includes a partition, a first inlet pipe, and a second inlet pipe. The partition divides an inside passage of the header tank into a first tank and a second tank. The first inlet pipe introduces a first fluid into the first tank. The second inlet pipe introduces a second fluid into the second tank. The first inlet pipe is inclined at a predetermined angle except a right angle relative to an outer surface of the header tank such that a flow direction of the first fluid flowing from the first inlet pipe to the first tank includes a component in a predetermined direction from a first end of the first tank provided with the partition to a second end of the first tank opposite to the first end.

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) 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.

An evaporator for a climate chamber, in particular for a constant climate chamber with temperature- and humidity control, comprising a first inlet, a second inlet and an outlet for a refrigerant, wherein the first inlet, the second inlet, and the outlet are connected with one another by a duct, and wherein the second inlet is disposed between the first inlet and the outlet, and a climate chamber with an evaporator.

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 channel, a second channel and a third channel along the width direction. The first widths of the first channel, the second channel and the third channel are decreased at a fixed ratio, thereby facilitating the control of the thickness of the microchannel flat tube and improving the heat exchange efficiency of the third channel.

There is disclosed a heat exchanger comprising at least one set of channels having a proximal end and a distal end, the set of channels comprising: a first channel defined by a first skin and a wall; and a second channel defined by a second skin and the wall, wherein the wall located between the first channel and the second channel comprises a first at least one aperture to allow fluid to pass through the wall from the first channel to the second channel.

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.

A heat exchange system for a surgical instrument includes a valve, a load, and a load conduit extending between the valve and the load. The load conduit delivers fluid from the valve to the load. The heat exchange system also includes an exhaust conduit that directs the fluid away from the valve. A portion of the load conduit is positioned so as to thermally transfer heat to a portion of the exhaust conduit.
