Further, the cross-sectional shape of the single heat dissipation channel 233 separated by the ribs 232 is approximately square, the width dimension of the ribs 232 is 1 to 3 mm, preferably 2 mm, so that the structural strength is high, and the dimension parameter of the cross-section of the single heat dissipation channel 233 arranged in square is 13 x 15 mm, so that the size design can reduce the possibility of external foreign matters entering the interior of the shell 100 as much as possible on the basis of ensuring the handle 200 to have better ventilation efficiency. While the above description describes the design of forming the heat dissipation channel 233 by matching the partition plate with the rib 231 and the rib 232 with the second protrusion 240, it will be appreciated that in other embodiments, the heat dissipation channel 233 may be formed in the wall of the second protrusion 240, that is, the wall of the second protrusion 240 may be designed to be relatively thick, and the heat dissipation channel 233 may be formed in the wall of the second protrusion 240 directly during the injection molding process, and in the above two embodiments, the opening of the heat dissipation channel 233 on the side close to the inner cavity of the housing 100 may be opened upwards, and of course, the opening of the heat dissipation channel 233 on the side close to the inner cavity of the housing 100 may also be opened horizontally.

In order to further improve the waterproof and anti-foreign-matter performance of the handle 200, the inner wall surface of the handle 200 is further connected with a baffle 250, and the baffle 250 is disposed close to the opening of the inner cavity of the housing 100 corresponding to the heat dissipation channel 233. In combination with the above, the opening of the heat dissipation channel 233 near the inner cavity of the housing 100 may be opened upwards or horizontally, and the arrangement of the baffle 250 corresponding to the opening of the heat dissipation channel 233 near the inner cavity of the housing 100 should be understood that the baffle 250 may shield the opening of the heat dissipation channel 233 near the inner cavity of the housing 100 at a certain viewing angle, and may block water and other foreign matters that flow into the inner cavity of the housing 100 from the heat dissipation channel 233 as much as possible. The two ends of the baffle 250 in the horizontal direction are connected with the enclosure frame 210, the side wall of one side of the baffle 250 is connected with the inner wall surface of the first protrusion 230, the dimension of the baffle 250 extending into the inner cavity in the horizontal direction is defined as the width dimension of the baffle 250, the width of the baffle 250 is larger than the width of the heat dissipation channel 233, and in combination with the above, the heat dissipation channel 233 extends upwards, and the baffle 250 is arranged at the interval of the end of the heat dissipation channel 233, so that under the condition that external rainwater or other foreign matters are gushed in, the baffle 250 can effectively prevent rainwater from continuing to the inner cavity of the shell 100 after gushing out of the heat dissipation channel 233 and impacting on the electronic component inside, and the safety performance of the air conditioner outdoor unit 300 can be greatly improved.

According to the application, the heat dissipation channel 233 is arranged at the bottom of the handle 200, and the inner cavity of the air conditioner outdoor unit 300 is communicated with the outside through the heat dissipation channel 233 to achieve heat exchange, so that a better heat dissipation purpose is achieved, and in order to further improve the waterproof property of the heat dissipation channel 233 in the heat dissipation process, the cross-sectional area of the heat dissipation channel 233 is reduced in the extending direction from the outside to the inner cavity of the shell 100. The design that the cross-sectional area of the heat dissipation channel 233 is reduced in the extending direction from the outside to the inner cavity of the housing 100 (i.e., the direction from bottom to top) can be realized by the arrangement that the partition 231 is inclined in the vertical direction and gradually approaches the side wall of the first protrusion 230 from bottom to top, and the design that the cross-sectional area of the heat dissipation channel 233 is reduced in the extending direction from the outside to the inner cavity of the housing 100 can further improve the waterproof and anti-foreign matter performance of the handle 200 when the external foreign matter impacts the inner cavity of the housing 100, because the external foreign matter is blocked by the inner wall of the heat dissipation channel 233 under the condition that the heat dissipation channel 233 is reduced, and the baffle 250 is inclined, the external foreign matter is also led to the outside of the housing 100. Further, the bottom wall 230a of the first protrusion 230 is set to be an inclined plane with an included angle between 0 and 90 degrees, and by the design that the bottom wall 230a of the first protrusion 230 is an inclined plane and the design that the partition plate 231 is also an inclined plane, rainwater for external impact is not easy to stay at the bottom of the first protrusion 230 because of the design of the inclined bottom wall 230a of the first protrusion 230 on one hand, and on the other hand, rainwater rushing into the heat dissipation channel 233 can be blocked by the partition plate 231, so that a better waterproof effect can be formed. Further, the angle between the baffle 250 and the inner wall surface of the first protrusion 230 is in the range of 0 to 90 degrees, and preferably 70 to 90 degrees, so that rainwater impinging upward from the heat dissipation channel 233 can be well blocked.

The baffle 250 is arranged in the first bulge 230, the baffle 250 can not only realize the blocking effect on external rainwater, but also play a role in assembly, and particularly, the baffle 250 is also provided with a mounting groove (not shown), wherein the mounting groove is formed by downwards sinking the baffle 250 arranged in a plate shape, and is clamped with the wiring terminal. The mounting groove of the present application is adapted to the outer shape of the terminal, and the mounting groove of the baffle 250 is simultaneously caught to the outer wall of the terminal after the handle 200 is fixed to the right side plate 140, whereby the handle 200 can also achieve the fixation of the internal electronic components of the air conditioner outdoor unit 300. And thus, the influence of vibration on the electronic components during the operation of the air conditioner outdoor unit 300 can be reduced.

The second protrusion 240 is located below the first protrusion 230, and is connected to the lower edge of the bottom wall 230a of the first protrusion 230 with the air passing hole 233a, and a routing channel 242 communicating with the inner cavity of the housing 100 and the wire passing hole 241 is formed around the second protrusion 240. The wiring channel 242 is a groove structure, and through the design of the wiring channel 242, the wiring connected with the wiring terminal can be converged through the wiring channel 242 and arranged into a wire harness, so that the wiring of the air conditioner outdoor unit 300 is not easy to block the opening of the heat dissipation channel 233 positioned at the inner side of the handle 200, and the external air can enter the inner cavity of the shell 100 more easily, thereby being beneficial to heat dissipation of the air conditioner indoor unit.

The application also provides an air conditioner, which comprises an air conditioner indoor unit and an air conditioner outdoor unit 300 connected with the air conditioner indoor unit, wherein the specific structure of the air conditioner outdoor unit 300 refers to the embodiment, and the air conditioner at least has all the beneficial effects brought by the technical schemes of the embodiment because the air conditioner adopts all the technical schemes of the embodiment, and the detailed description is omitted. Of course, the air conditioner further includes an air conditioner indoor unit, and since the connection manner of the air conditioner indoor unit and the air conditioner outdoor unit 300 is known to those skilled in the art, a detailed description thereof will not be provided.

The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the scope of the application, and all equivalent structural changes made by the description of the present application and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the application.
