The diversion cavity 2 is arranged in a truncated cone shape, and a diversion tube 3 is provided at the end of the diversion cavity 2 away from the first flow tube 1. The diversion tube 3 is arranged in a plurality of equidistant rings around the diversion cavity 2, and the top of the first diversion guide plate 403 is arranged in a circular shape. The interception plate 405 is arranged at the notch position of the drainage groove 404, and the bottom end of the second diversion guide plate 406 is arranged in a herringbone shape, and the bottom ends of the second diversion guide plate 406 are respectively connected to two adjacent diversion tubes 3.

[0018] According to the above embodiments, it should be noted that: when in use, the refrigerant enters the diversion chamber 2 from the first flow tube 1. When the refrigerant enters, the arc-shaped protrusion block 401 guides the refrigerant to the middle, and the protrusion block 401 reduces the flow pipe, making the flow direction of the refrigerant more concentrated. The gathered refrigerant flows down from the middle of the protrusion block 401 and flows down along the inclined surface of the diversion inclined plate 402.

[0019] After passing through the protruding block 401 , the refrigerant will be intercepted from the middle by the first diversion guide plate 403 , so that it is diverted. The refrigerant is forced to flow downward from the guide groove 404 , and the first diversion guide plate 403 performs the first diversion on the refrigerant.

[0020] The diverted refrigerant will be intercepted and divided for the second time by the interception plate 405, and then flow downward through the human-shaped second diversion guide plate 406. The human-shaped second diversion guide plate 406 divides and guides the refrigerant to both sides, so that it is diverted and flows into two adjacent diversion pipes 3.

[0021] The first flow dividing guide plate 403 and the second flow dividing guide plate 406 divide the refrigerant multiple times, which can further enhance the uniform distribution of the refrigerant when the refrigerant in the first flow tube 1 flows to the flow dividing tube 3 .

[0022] See also Figure 1-3As shown, a diverter for an air-conditioning evaporator includes a raised block 401 arranged in an arc shape near one end of the first flow tube 1, the top of the drainage inclined plate 402 is fixedly connected to the bottom end of the raised block 401, and the diverter chamber 2 is away from one end of the first flow tube 1 and is located on the inner side of the diverter tube 3 with an installation docking groove 5.

[0023] According to the above embodiments, it should be noted that the arc shape of the protruding block 401 is set to better collect the refrigerant.

[0024] To sum up, the use process of the device is as follows: when in use, the refrigerant enters the diversion chamber 2 from the first flow tube 1. When the refrigerant enters, the arc-shaped protrusion block 401 guides the refrigerant to the middle, and the protrusion block 401 reduces the flow pipe, making the flow direction of the refrigerant more concentrated. The gathered refrigerant flows down from the middle of the protrusion block 401 and flows down along the inclined surface of the diversion inclined plate 402.

[0025] After passing through the protruding block 401 , the refrigerant will be intercepted from the middle by the first diversion guide plate 403 , so that it is diverted. The refrigerant is forced to flow downward from the guide groove 404 , and the first diversion guide plate 403 performs the first diversion on the refrigerant.

[0026] The diverted refrigerant will be intercepted and divided for the second time by the interception plate 405, and then flow downward through the human-shaped second diversion guide plate 406. The human-shaped second diversion guide plate 406 divides and guides the refrigerant to both sides, so that it is diverted and flows into two adjacent diversion pipes 3.

[0027] The first flow dividing guide plate 403 and the second flow dividing guide plate 406 divide the refrigerant multiple times, which can further enhance the uniform distribution of the refrigerant when the refrigerant in the first flow tube 1 flows to the flow dividing tube 3 .
