Some cabinets have a hollow heat dissipation structure, such as a high voltage power distribution cabinet with a dustproof heat dissipation function disclosed in CN215897012U, and the structure of the cabinet body cover can perform a heat dissipation function. However, if water leaks from the ceiling, water may accumulate therein and eventually flow into the cabinet through the heat dissipation opening, damaging the electronic devices, or even causing accidents.

There is a need for an improved structure to solve the above problems.

Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 1 to 3, the utility model discloses a prevent outer quick-witted heat dissipation dome of ponding room, including hypoplastron 1 and the cover body 2 that is located hypoplastron 1 top, hypoplastron 1 and cover body 2 enclose into an inner chamber 3, are equipped with on the hypoplastron 1 to be used for communicateing inner chamber 3 and the inside vent 11 of off-premises station, and intercommunication inner chamber 3 and external heat radiation structure 21 have been seted up downwards to the edge of the cover body 2, and the edge height of vent 11 is higher than heat radiation structure 21's height. When the outdoor unit is in operation, the internal air circulation system allows air to pass through the ventilation opening 11 into the inner cavity 3 and then to be discharged from the heat dissipation structure 21, so as to help the outdoor unit discharge heat more quickly. Because the heat radiation structure 21 is arranged downwards, the heat radiation structure can be subjected to an IPX 4-grade spraying test, the rainwater is ensured to be vertically hit on the top cover in the forward direction and not to be splashed into the interior under the wind and rain environment, and the outdoor waterproof requirement is met. Even if the cover body 2 leaks, water drops fall to the upper side of the lower plate 1, and because the edge of the vent hole 11 is higher than the heat dissipation structure 21, the accumulated water flows to the lower side, does not flow through the vent hole 11, and is preferentially discharged from the heat dissipation structure 21. The lower plate 1 may be an inverted funnel structure with the heat dissipation structure 21 at the lowest position, and the heat dissipation structure 21 may be a large hole or a plurality of small holes. This heat dissipation overhead guard can not only form cover body heat dissipation channel through inner chamber 3, still can utilize the louvre to discharge ponding when inner chamber 3 intakes moreover, has guaranteed that the rainwater can not splash into in the cabinet and damage electronic component, has reduced the corrosion probability and has leaked the risk.

As shown in fig. 2 and 3, the lower plate 1 has a planar structure, and a water blocking frame 12 for blocking the accumulated water from overflowing into the vent hole is provided at an upper portion of the vent hole 11. The lower plate 1 is convenient to manufacture, and can not enter the cabinet through the vent 11 as long as accumulated water in the inner cavity 3 does not exceed the height of the water retaining frame 12.

As shown in fig. 2, the heat dissipation structure 21 is a plurality of heat dissipation holes arranged side by side at the edge of the cover 2. If water drops seep into the inner cavity 3, the water drops generally slide to the edge position along the inner wall of the cover body 2, so that the heat dissipation holes are formed in the edge to discharge accumulated water more quickly.

As shown in fig. 1 and 3, the cover 2 has a herringbone slope structure. The herringbone slope structure is a structure combining the positive inclined plane and the negative inclined plane, the heating area of the illumination surface can be reduced, the weather influence is reduced, and the energy consumption of an air conditioner is reduced.

As shown in fig. 3, the slope of the cover 2 does not exceed 15 °. The projection range of the cover body 2 is approximately equal to the cross section of the outdoor unit, and the larger the gradient is, the larger the height of the top cover is, and the larger the volume is. In fact, as long as the cover body 2 has a certain inclination, the rain water can fall off, the heat dissipation does not need large volume, and the smaller the heat dissipation is, the more difficult the hot air is trapped in the dead angle of the inner cavity 3, so the inclination is not suitable to be too large.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which all fall within the scope of the invention.
