Thus, features defined as "first", "second" and "third" may explicitly or implicitly include one or more of the features.

[0021] A preferred embodiment of the present application is as follows Figures 1 to 6 As shown, an air-conditioning outdoor unit with a heat dissipation structure includes an outdoor case 1, the interior of the outdoor case 1 includes a compressor cavity 100 and a fan cavity 200, and the compressor cavity 100 and the fan cavity 200 are connected through a first heat dissipation grille 300; an electric control box 11 is provided on the top of the compressor cavity 100, and the projection of the electric control box 11 to the surface where the first heat dissipation grille 300 is located is directly opposite to the first heat dissipation grille 300; an air inlet louver structure 12 is provided on the rear side of the outdoor case 1, and the air inlet louver structure 12 is connected to the compressor cavity 100; a handle structure 13 is provided on the right side of the outdoor case 1, and second heat dissipation grilles 131 are respectively provided on the front and rear sides of the handle structure 13, and the second heat dissipation grilles 131 are respectively connected to the compressor cavity 100.

[0022] In this embodiment, the fan chamber 200 is used to install the outdoor fan of the air conditioner outdoor unit, the compressor chamber 100 is used to install the compressor of the air conditioner outdoor unit, and the top of the compressor is provided with an electric control box 11 for electrically controlling the operation of the air conditioner outdoor unit, and the left and right sides of the outdoor unit case 1 are provided with handle structures 13, so that the installer can lift the outdoor unit case 1 through the handle structures 13. Specifically, when the air conditioner outdoor unit is working, due to the pressure difference generated when the outdoor unit wind wheel rotates, the ambient temperature air will be sucked into the compressor chamber 100 from the air inlet louver structure 12 and the second heat dissipation grille 131, and then enter the fan chamber 200 from the first heat dissipation grille 300. Because the electric control box 11 is arranged opposite to the first heat dissipation grille 300, after the ambient temperature air enters the compression chamber, when it passes through the first heat dissipation grille 300, the ambient temperature air will take away the heat of the electric control box 11, thereby reducing the temperature of the electric control box 11 and preventing the electric control box 11 from being burned due to high temperature.

[0023] More preferably, the handle structure 13 is provided with an air collecting chamber 130 and an air guide plate 132, and the second heat dissipation grille 131 is connected to the air collecting chamber 130; the air guide plate 132 includes a vertical mounting plate 1321 and an inclined guide plate 1322; the vertical mounting plate 1321 is installed on the side where the air collecting chamber 130 is connected to the compressor chamber 100, the bottom of the inclined guide plate 1322 is fixedly connected to the top of the vertical mounting plate 1321, and the other side of the inclined guide plate 1322 extends obliquely toward the direction of the electric control box 11.

[0024] In this embodiment, the vertical mounting plate 1321 is installed on the left side of the air collecting chamber 130, and the top of the inclined guide plate 1322 is inclined to the upper left. The purpose of this arrangement is to guide the ambient temperature air to the electric control box 11 to avoid the dispersion of the ambient temperature air, so as to more effectively take away the heat of the electric control box 11 and avoid the electric control box 11 from being burned by high temperature.

[0025] Furthermore, the vertical mounting plate 1321 is also provided with an array of air inlet holes 1300. Such a configuration is intended to accelerate the entry of ambient temperature air into the compressor chamber 100, thereby accelerating the speed at which the ambient temperature air takes away the heat of the electric control box 11, thereby ensuring heat dissipation efficiency.

The purpose of such arrangement is that the heat generated by the electric control component 111 can be dissipated to the outside of the electric control box 11 through the plurality of heat dissipation circular holes 112, so as to avoid the heat being concentrated in the electric control box 11, thereby preventing the electric control component 111 from being damaged due to high temperature.

[0027] Specifically, a first connecting plate 113 is also provided on the top of the electric control box 11, and the first connecting plate 113 is provided with a first connecting hole 1131; a second connecting plate is also provided on the surface where the first heat dissipation grille 300 is located, and the second connecting plate is provided with a second connecting hole 301; the first connecting hole 1131 and the second connecting hole 301 are connected in sequence by a connecting member, so that the electric control box 11 is fixedly installed on the top of the compressor cavity.

[0028] Furthermore, a snap-in protrusion 114 protruding toward the surface where the first heat dissipation grille 300 is located is provided at the bottom of the electric control box 11, and the snap-in protrusion 114 is provided with a snap-in protrusion 1141; a snap-in opening 302 is provided on the surface where the first heat dissipation grille 300 is located, and the snap-in opening 302 is provided with a snap-in groove 3021 protruding toward the direction of the electric control box 11.

[0029] In this embodiment, the electric control box 11 first clamps the clamping protrusion 1141 on the clamping groove 3021 for pre-installation, and the electric control box 11 has a gap between the electric control box 11 and the surface where the first heat dissipation grille 300 is located due to the clamping protrusion 114, so as to facilitate the heat flow of the electric control box 11, avoid heat concentration between the electric control box 11 and the surface where the first heat dissipation grille 300 is located, and ensure that the electric control box 11 is not affected by high temperature. After the pre-installation is completed, the electric control box 11 is fixed with screws.

[0030] Preferably, the surface of the electric control box 11 facing the first heat dissipation grid 300 is further provided with a heat dissipation fin structure 115.
