The structure of the application does not influence the heat radiation performance, and ensures the timely and efficient heat radiation effect on the inside of the cabinet body.

In the first chamber 1, a filter screen can be paved at the water outlet 12 to prevent impurities such as leaves entering along with rainwater from entering the drainage channel 3 and prevent the drainage channel 3 from being blocked.

In some embodiments, along the direction gradually approaching the water outlet 12, the chamber bottom wall 11 of the first chamber 1 is gradually inclined, that is, the chamber bottom wall 11 is inclined, and may be in a slope shape, and the lower end forms a water diversion low position and is provided with the water outlet 12, so that rainwater entering the first chamber 1 from the air inlet and the air outlet can quickly flow to the water outlet 12 along the chamber bottom wall 11. Or the bottom wall 11 of the first chamber 1 is recessed in a step shape along the direction gradually approaching the water outlet 12, so as to form a diversion low position. In this way, rainwater can also flow rapidly along the bottom wall 11 of the chamber towards the water outlet 12.

The chamber bottom wall 11 of the first chamber 1 may be planar, such as at least the main body area of the chamber bottom wall 11 being planar. So arranged, the chamber bottom wall 11 of the first chamber 1 may be formed by a flat plate-like partition plate for easy manufacture. Or, one or more water diversion channels are arranged on the bottom wall 11 of the first chamber 1, for example, the water diversion channels extend along the direction from the high-level area to the low-level area, and each water diversion channel is led to the water outlet 12 and is communicated with the water outlet 12. By doing so, even when the amount of rainwater entering the first chamber 1 is large, the water level can be prevented from rising, and the rainwater can be prevented from soaking the bottom end region of the member contacting the chamber bottom wall 11 in the first chamber 1. The water diversion channel can be a linear groove, an arc groove or a bending groove. For example, the water diversion channel has an arc-shaped section or at least two bending sections which are communicated with each other at an included angle. By the arrangement, the length of the water diversion flow passage can be prolonged, the water retention capacity is improved, and the water can absorb heat, so that the heat exchange effect of the first chamber 1 and the electric control chamber 2 can be enhanced.

As shown in fig. 1, the chamber bottom wall 11 of the first chamber 1 is inclined in a first direction (X direction shown in the drawing), and the first direction may be the width direction of the cabinet or the length direction of the cabinet. The chamber bottom wall 11 has a higher end and a lower end in the first direction, and the water outlet 12 is provided at the lower end, also in a lower region of the chamber bottom wall 11 in the first direction.

When the water diversion low position is disposed in the area of the chamber bottom wall 11 near the chamber side wall, because the water diversion low position is close to the chamber side wall (one, two or more chamber side walls), in order to avoid frequent impact or soaking of rainwater on the chamber side wall (the chamber side wall near the water diversion low position and near the water outlet), in some embodiments, as shown in fig. 4, a water baffle 5 is disposed at the water diversion low position, i.e. on the chamber bottom wall, the water baffle 5 is disposed at the inner side of the chamber side wall (the side closer to the interior of the cabinet or the chamber bottom wall), the water baffle 5 extends in the same direction as the chamber side wall in the length or width direction of the cabinet, and at least part of the area of the water outlet 12 is disposed at the side of the water baffle 5 away from the chamber bottom wall 11, i.e. the side closer to the high position area, so that a large amount of rainwater flowing down from the high position area does not directly impact on the chamber side wall near the low position area and flows to the water outlet 12 along the water baffle 5. The water deflector 5 may be spaced from the chamber side wall. If an air inlet or an air outlet is provided on the side wall of the chamber adjacent to the lower region of the bottom wall 11 of the chamber, the water baffle 5 is spaced from the side wall of the chamber, a part of the water outlet 12 is located on one side of the water baffle 5 in the thickness direction, and a part of the water outlet is located on the other side of the water baffle 5 in the thickness direction. Thus, rainwater on both sides of the water baffle 5 flows into the water outlet 12.

Or the inner side of the side wall of the cavity, the bottom wall 11 of the cavity is not provided with the water baffle 5, but is provided with a water baffle groove which also extends along the same direction with the side wall of the cavity in the length or width direction of the cabinet body, the water baffle groove and the side wall of the cavity can have a distance, and the water baffle groove is communicated with the water outlet 12. In this way, a large amount of rainwater flowing down from the high-level region does not directly strike the side wall of the chamber adjacent to the low-level region, but flows into the water blocking groove and then flows to the water outlet 12 along the water blocking groove.

The cabinet body is provided with a cabinet door, such as the cabinet body includes the side cabinet board that sets up along the direction of height, is provided with the cabinet door on one of them side cabinet board, or this side cabinet board can open and shut the setting and form the cabinet door. The drainage channel 3 can be arranged adjacent to the cabinet door or arranged along the circumferential direction of the cabinet body.

The whole or partial section of the drainage channel 3 forms a drainage section arranged along the height direction of the cabinet body, and the drainage section is arranged on the side wall of the cabinet body. The drainage section is integrally formed with the side wall of the cabinet body, or is connected with the side wall of the cabinet body, and when the drainage section is connected with the side wall of the cabinet body, the drainage section is detachably connected with or fixedly connected with the side wall of the cabinet body. For example, the drainage section is made of metal, for example, the drainage section is made of the same material as a cabinet plate forming the cabinet body, and the drainage channel 3 can be integrally formed with the side wall of the cabinet body, namely the side plate of the cabinet body, or welded with the side wall of the cabinet body, or detachably connected with the side wall of the cabinet body through connecting pieces such as fasteners. If the drainage section of the drainage channel 3 is a rubber tube or a plastic tube, the drainage section can be detachably connected with the side wall of the cabinet body through connecting pieces such as a clamp, or a fixing structure is arranged on the side wall of the cabinet body, and the drainage section is fixed on the side wall of the cabinet body through the fixing structure, and the fixing structure can comprise a clamp ring or a groove and the like.

In some embodiments, a water blocking structure is further disposed at the air inlet and/or the air outlet to reduce the amount of rainwater entering the cabinet. For example, as shown in fig. 1, 3 and 5, the side wall of the cabinet body is provided with a protruding strip 4, the bottom end surface of the protruding strip 4 facing the ground is provided with a vent 41 communicated with the first chamber 1, and the vent 41 forms an air inlet or an air outlet, so that rainwater can be effectively prevented from entering the cabinet body. Or, the air inlet and/or the air outlet are/is provided with a water blocking plate, the top end of the water blocking plate is connected with the cabinet body, and the distance between the water blocking plate and the air inlet is gradually increased along the height direction. Therefore, part of rainwater can be prevented from entering the cabinet body, and the rainwater amount entering the cabinet body is reduced.
