Optionally, the evaporator 200 includes a primary heat exchange section 210 and a secondary heat exchange section 220 connected to each other, and an included angle is formed between the primary heat exchange section 210 and the secondary heat exchange section 220, so that the evaporator 200 can adapt to the shape of the casing 100, thereby not only facilitating to increase the area of the evaporator 200 facing the air inlet 110, that is, facilitating to increase the heat exchange area between the evaporator 200 and the air; and is beneficial to enlarging the area of the air inlet 110 on the casing 100, so as to increase the air inlet volume of the vertical air-conditioning indoor unit and improve the cooling or heating efficiency of the vertical air-conditioning indoor unit.
Optionally, the length of the primary heat exchange section 210 is greater than the length of the secondary heat exchange section 220, so that on one hand, the primary heat exchange section 210 can fully exert heat exchange capacity; on the other hand, the end of the secondary heat exchange section 220 away from the primary heat exchange section 210 is made to have a space that is more expensive to arrange for other components.
Optionally, the primary heat exchange section 210 and the secondary heat exchange section 220 are integrally formed, so that the evaporator 200 is formed into a continuous structure, which is favorable for improving the heat exchange effect of the evaporator 200. Of course, the primary heat exchange section 210 and the secondary heat exchange section 220 may also be two parts connected to each other, as long as the requirements of the present embodiment can be met, and the description is omitted here.
