According to an embodiment of the present invention, as shown in fig. 5, there is further provided an indoor unit of an air conditioner, including a heat exchanger 100, where the heat exchanger 100 is the above-mentioned heat exchanger, specifically, the indoor unit of an air conditioner further includes a casing 101, an air duct 102 is provided inside the casing 101, a fan 105 is provided inside the air duct 102, one end of the air duct 102 has a first air opening 103 and a second air opening 104, the heat exchanger 100 is provided at the first air opening 103 or at the second air opening 104, as shown in fig. 5, the heat exchanger 100 is provided at the first air opening 103, specifically, the first air opening 103 is provided at a lower portion of the casing 101, and has a plurality of air openings, the plurality of air openings are provided around a circumferential direction of the casing 101, the fan 105 rotates in a first direction, for example, so that an external air flow can flow out through the first air duct 103, the heat exchanger 100, the air opening 102, and the second, at this time, corresponding to the cooling condition of the air conditioner, and at this time, correspondingly controlling the refrigerant in the heat exchanger 100 to flow from the first tube bank 11 (inside the heat exchanger 100 in fig. 5) to the second tube bank 12 (outside the heat exchanger 100 in fig. 5), so as to make the refrigerant and the air flow form a reverse flow, in the same way, when the fan 105 rotates in the first direction, for example, so that the external air flow can flow out through the second air opening 104, the air duct 102, the heat exchanger 100 and the first air opening 103 to form an air circulation, corresponding to the heating working condition of the air conditioner, and at this time, the refrigerant in the heat exchanger 100 is correspondingly controlled to flow from the second tube bank 12 (outside the heat exchanger 100 in fig. 5) to the first tube bank 11 (inside the heat exchanger 100 in fig. 5), therefore, the refrigerant and the air flow form reverse flow, and the heat exchanger 100 can have better heat exchange efficiency when the air conditioner is in a heating working condition or a refrigerating working condition. The first air openings 103 and/or the second air openings 104 are multiple, and the multiple first air openings 103 and/or the multiple second air openings 104 are respectively arranged in a one-to-one correspondence manner with the multiple heat exchange surfaces 3 of the heat exchanger 100.
Furthermore, the first air opening 103 is located at the lower end of the air duct 102, the heat exchanger 100 is disposed at the first air opening 103, a water pan is disposed at the lower portion of the heat exchanger 100, the water pan is used for receiving condensed water formed by the heat exchanger 100, the position of the first heat exchange tube group 1 with a large refrigerant main tube pass in the heat exchanger 100 is higher than the position of the first heat exchange tube group 1 with a small refrigerant main tube pass, the refrigerant main tube pass refers to the tube passes of all U-shaped tubes 2 in the group of the first heat exchange tube groups 1, and in general, the structural style and specification of the U-shaped tubes 2 adopted in one heat exchanger are the same, at this time, as shown in fig. 2, for example, at this time, the first air opening 103 is air outlet corresponding to an air conditioner, and because the lower end of the heat exchanger 100 is blocked by the water pan, the static pressure of the air outlet at a lower position is higher, thereby make the air-out air current of first wind gap 103 great and the higher position velocity of flow of the lower position velocity of flow in the aspect of height, and through aforementioned technical scheme, in the big position of the 100 velocity of flow of heat exchanger, set up less U type pipe, in the position that the velocity of flow is a little, then set up more U type pipe to make 100 refrigerant outlet temperatures of heat exchanger keep unanimous, so the whole heat transfer effect of heat exchanger is better, also can not appear the condition of condensation because the difference in temperature is too big during refrigeration. Specifically, for example, as shown in fig. 2, a first heat exchange tube group 1 from a first group to a fourth group is defined from top to bottom with reference to the orientation shown in the figure, wherein the fourth group has 5U-shaped tubes 2 (i.e., refrigerant main tube pass), which are respectively 3 in the inner row and 2 in the outer row; the third group has 5U-shaped tubes 2 (namely refrigerant main tube pass), which are respectively 2 in the inner row and 3 in the outer row; the second group and the first group respectively have 6U-shaped tubes 2 (i.e. refrigerant main tube pass), and 3 inner rows and 3 outer rows, respectively, when the first air port 103 is used as an air outlet (the air conditioner is in a heating condition), due to the plugging action of a lower water receiving tray, a wind pressure static pressure is formed, so that the airflow velocity of the first air port 103 from bottom to top in height decreases progressively, that is, the airflow velocity at a position with a lower height is larger and the airflow velocity at a position with a higher height is smaller, correspondingly, the first heat exchange tube group 1 has fewer U-shaped tubes 2 (e.g. 5U-shaped tubes of the third group and the fourth group) at a position with a larger airflow velocity, and has more U-shaped tubes 2 (e.g. 6U-shaped tubes of the first group and the second group) at a position with a smaller airflow velocity.
