The evaporator 200 and the fan 300 are disposed in the upper space of the cabinet 100, and are sequentially disposed inside the air return opening 110. The compressor 400 is disposed in the lower space of the cabinet 100. As shown in fig. 4, the electrical box 500 is disposed in the cabinet 100 and below the air return opening 110. In the present embodiment, the electrical box 500 is located directly below the evaporator 200. A driving plate 510 is provided in the appliance case 500.
As shown in fig. 3, the heat dissipation device 600 includes a heat sink 610 and a rectification wind cover 620.

The rectification wind cover 620 covers the outside of the heat sink 610. The upper and lower ends of the rectification wind cover 620 are opened, and a ventilation air duct is formed inside the rectification wind cover. Referring to fig. 4, the negative pressure at the air return side of the indoor unit causes the ventilation air duct to form a bottom-to-top airflow, and the airflow flows through the ventilation air duct from bottom to top, exchanges heat with the heat sink 610, and then enters the cabinet 100 through the air return opening 110. The air-conditioning indoor unit of the invention utilizes the negative pressure return air at the return air side of the cabinet body 100, and the rectification air cover 620 is added on the outer surface of the radiator 610, so that the pressure difference is formed between the upper part and the lower part of the ventilation air channel, and the heat dissipation is carried out by flowing through the radiator 610, and meanwhile, the rising flow of the air flow is accelerated by utilizing the principle of hot air rising, and the heat exchange efficiency of the heat dissipation device 600 is improved.
In the air-conditioning indoor unit, the air volume flowing through the radiator 610 is increased by increasing the vertical rectification fan cover 620 by using the return air field of the air-conditioning indoor unit, and the effect of cooling and radiating the drive plate 510 of the electrical box 500 is realized by using the chimney effect of rising hot air, and the radiating device 600 is positioned on the return air side of the indoor unit, so that the influence on the air volume of the whole unit is small; the air field is adopted for cooling, so that the air conditioner fluorine system is not interfered, and the reliability is higher; the device such as fan need not additionally to increase, simple structure, the cost is lower.
In the present embodiment, referring to fig. 5 and 6, the rectification wind cover 620 includes a wind cover body 621 and a wind cover baffle 622 disposed on an upper side of the wind cover body 621. The fan housing body 621 is fixedly connected to the cabinet 100. Specifically, the side surface of the fan housing body 621 is provided with a bent edge 6212 which is turned over outwards, and the bent edge 6212 can be fixedly connected with the cabinet 100 through a fastener such as a screw. The fan housing baffle 622 extends upward along the fan housing body 621, and the upper end of the fan housing baffle 622 is higher than the lower edge of the air return opening 110 and is disposed outside the air return opening 110. The fan housing baffle 622 is higher than the lower edge of the air outlet/return opening 110, so that the pressure difference between the upper and lower parts of the ventilation air duct can be increased, the airflow speed can be increased, the air volume flowing through the ventilation air duct can be increased, and the heat exchange efficiency of the heat dissipation device 600 can be further improved.
In the present embodiment, the fan housing body 621 and the fan housing baffle 622 are integrally formed, and have a rectangular frame structure. As shown in fig. 6, the width dimension of the rectification wind shield 620 is W, the height of the wind shield baffle 622 is h1 (the dimension of the rectification wind shield 620 higher than the lower edge of the air return opening 110), the air volume flowing through the radiator 610 can be adjusted by changing the dimensions W and h1 of the rectification wind shield 620, and the radiator 610 is increased along with the increase of W and h1 on the premise that the bottom intake air is kept to completely flow through the radiator 610.
In another embodiment, the fan housing body 621 and the fan housing baffle 622 are separate structures. Further, the fan cover stopper 622 is slidably connected to the fan cover body 621 and can slide up and down along the fan cover body 621. A lifting device is connected between the fan housing baffle 622 and the fan housing body 621, and the lifting device is used for adjusting the fan housing baffle 622 to slide up and down. By arranging the lifting device, the height h1 of the rectification fan cover 620 can be adjusted at any time, so that the air speed required by the radiator 610 can be adjusted at any time, and the influence on the air volume of the whole machine is reduced as much as possible. The lifting device can be a gear rack lifting mechanism and the like, and can be driven in an automatic mode or a manual mode through a motor, hydraulic drive and the like.
In order to optimize the heat dissipation temperature field around the heat sink 610 and improve the heat dissipation efficiency, the rectification fan housing 620 is provided with a heat dissipation air return opening, and the heat dissipation air return opening includes a plurality of heat dissipation ventilation holes 6211. The heat sink return air opening may define a height h2 of the area of bottom heat sink vents 6211 based on the location of the IPM module driver board 510. Because the heating temperatures of the heat sink 610 are different, the heat dissipation air return opening is disposed at a lower position of the highest temperature region of the heat sink 610, so as to improve the heat dissipation effect.
In this embodiment, the electrical box 500 and the heat sink 610 are disposed at the lower side of the air return opening 110, and preferably disposed at a position away from the air return opening, because the farther away from the air return opening, the longer the fan housing is, the better the chimney effect is formed, and the larger the heat dissipation air return air volume is, the better the heat dissipation effect is.
In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
