Evaporator

An evaporator, comprising:

• a housing, wherein the housing has a cavity, and the cavity has a length direction, a width direction, and a height direction;
• a first heat exchange tube set and a second heat exchange tube set, wherein heat exchange tubes in the first heat exchange tube set and the second heat exchange tube set extend along the length direction of the cavity, and are arranged along the width direction and the height direction of the cavity, and the first heat exchange tube set is located above the second heat exchange tube set, wherein in the width direction of the cavity, a first number of columns of the first heat exchange tube set is greater than a second number of columns of the second heat exchange tube set;
• a first side heat exchange tube baffle device and a second side heat exchange tube baffle device, wherein the first side heat exchange tube baffle device and the second side heat exchange tube baffle device are disposed on opposite sides of the first heat exchange tube set and the second heat exchange tube set in the width direction of the cavity, respectively, and are arranged along outer contours of the first heat exchange tube set and the second heat exchange tube set;
• and
• a redistribution device, wherein the redistribution device is disposed between the first heat exchange tube set and the second heat exchange tube set, and two ends of the redistribution device in the width direction of the cavity are connected to the first side heat exchange tube baffle device and the second side heat exchange tube baffle device, respectively, wherein the redistribution device extends along the length direction of the cavity to cover a top of the second heat exchange tube set, and is a distance from a lower part of the first heat exchange tube set, the redistribution device is provided with a plurality of rows of holes, each row of holes of the plurality of rows of holes is arranged along an extending direction of the heat exchange tubes, and each row of holes of the plurality of rows of holes is aligned with a corresponding column of heat exchange tubes in the second heat exchange tube set.
