Detailed Description

Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.

An electrical box 100 according to an embodiment of the present invention will be described with reference to fig. 1 to 4, and an outdoor unit of an air conditioner having the electrical box 100 is also provided.

As shown in fig. 1 and 2, the electrical box 100 includes: the reactor includes a case 10 and a top cover 20, a housing space 13 for housing a reactor 40 is formed in the case 10, the reactor 40 is disposed in the housing space 13, and the reactor 40 is fixed to the case 10.

Wherein, the top of the housing 10 is provided with a first heat dissipation hole 111 communicated with the accommodation space 13, the first heat dissipation hole 111 protrudes out of the top of the housing 10, the top cover 20 covers the top of the housing 10, the top cover 20 is provided with a drain hole 21, and the projection of the drain hole 21 on the top cover 20 is spaced from the first heat dissipation hole 111. That is, when water flows onto the case 10 along the drain hole 21, the water does not directly drip into the case 10 through the first heat-radiating hole 111, but drips on the top of the case 10 around the first heat-radiating hole 111. In addition, the first heat dissipation hole 111 protrudes from the top of the housing 10, so that water does not flow into the first heat dissipation hole 111 when flowing on the upper surface of the housing 10, the electrical box 100 thus configured can have a waterproof effect, and the reliability of the reactor 40 can be improved. Accordingly, the electrical box 100 thus provided also has a fire-proof effect at least to some extent.

And, the top of the top cover 20 and the top of the housing 10 are spaced apart to leave the air passage 30 communicating the water discharge hole 21 and the first heat dissipation hole 111, so that the air flow can be facilitated to flow in the air passage 30 between the top cover 20 and the housing 10.

With this arrangement, when water enters between the top cover 20 and the case 10 through the water discharge hole 21, the water flows out along the outside of the case 10, so that the water can be prevented from entering the inside of the case 10 and causing a short circuit of the reactor 40. In addition, the first heat radiation hole 111 is provided at the upper end of the case 10, and heat generated from the reactor 40 is radiated to the outside along with the airflow along the first heat radiation hole 111, the gas passage 30, and the water discharge hole 21, so that the reactor 40 can be radiated.

Therefore, the first heat dissipation hole 111 communicating with the accommodating space 13 is opened at the top of the housing 10, and the first heat dissipation hole 111 and the projection of the drain hole 21 on the housing 10 are arranged at an interval, so that water does not directly drop into the housing 10 when entering between the housing 10 and the top cover 20 from the drain hole 21. The first heat radiation hole 111 protrudes from the top of the case 10, and water dropped on the upper surface of the case 10 does not flow into the case 10. In addition, the air flow flows to the outside from the first heat dissipation hole 111, the gas passage 30, and the water drain hole 21, so that heat dissipation of the reactor 40 can be achieved, and excessive temperature of the reactor 40 is avoided.

As shown in fig. 2, a first protrusion 112 is formed at the top of the housing 10, and a first heat dissipation hole 111 is formed at the top end of the first protrusion 112. By arranging the first protrusion 112 on the top of the housing 10, when the first heat dissipation hole 111 is formed in the first protrusion 112, the first heat dissipation hole 111 protrudes out of the upper surface of the housing 10, and water flowing onto the housing 10 is blocked by the first protrusion 112, so that the water does not flow into the first heat dissipation hole 111, and the short circuit of the reactor 40 is avoided. The first protrusion 112 may have an arc-shaped side cross-section.

As shown in fig. 3, a second protrusion 22 is disposed on the top cover 20 at a position corresponding to the first protrusion 112, the second protrusion 22 protrudes from the top of the top cover 20, and the gas channel 30 is left between the first protrusion 112 and the second protrusion 22. By providing the second protrusion 22 at the position of the top cover 20 corresponding to the first protrusion 112, a gap is formed between the first protrusion 112 and the second protrusion 22, so that the air flow can be conveniently discharged from the first heat dissipation hole 111. In addition, the diameter of the first protrusion 112 is smaller than that of the second protrusion 22, so that the airflow can be discharged from the drainage hole 21 after flowing out from the first heat dissipation hole 111.

Further, a supporting column is disposed on one side of the top cover 20 facing the housing 10, one end of the supporting column is connected to the top cover 20, and the other end of the supporting column abuts against the housing 10, so that the first protrusion 112 and the second protrusion 22 are disposed at an interval. The first protrusion 112 and the second protrusion 22 can be arranged at intervals by arranging the supporting columns, so that the airflow can be discharged from the drainage hole 21 after flowing out of the first heat dissipation hole 111.

As shown in fig. 3, a plurality of third protrusions 23 are disposed on the top of the top cover 20, the plurality of third protrusions 23 are disposed on the periphery of the second protrusion 22, and a drainage hole 21 is disposed on a side of the third protrusion 23 away from the second protrusion 22. Through set up a plurality of third archs 23 at the top of top cap 20, the wash port 21 has been seted up to the third arch 23 one side that deviates from second arch 22, because wash port 21 does not set up upwards, so water is difficult to flow between top cap 20 and casing 10 from wash port 21 to can further avoid rivers to the casing 10 in. The third protrusion 23 may be a bar shape, and a rib for supporting and spacing may be provided therein.

And, the second protrusion 22 and the third protrusion 23 are located on the same height horizontal plane, so that a certain height difference can be formed between the second protrusion and the bottom of the top cover 20, thereby forming a drainage water tank on the top cover 20, and facilitating water to flow away from the drainage water tank. And, a part of the water flows between the top cover 20 and the housing 10 from the drain hole 21.

In addition, as shown in fig. 1 and 4, the bottom of the housing 10 is provided with a second heat dissipation hole 121, and the second heat dissipation hole 121 is disposed opposite to the first heat dissipation hole 111 to form convection in the accommodating space 13. By arranging the second heat dissipation hole 121 at the bottom of the housing 10, the airflow can also flow out of the electrical box 100 through the second heat dissipation hole 121, so that the heat dissipation efficiency of the electrical box 100 can be enhanced. Certainly, convection can be formed between the first heat dissipation hole 111 and the second heat dissipation hole 121 in the accommodation space 13, and the airflow enters the housing 10 from the second heat dissipation hole 121 and is discharged to the outside through the first heat dissipation hole 111, the air channel 30 and the drainage hole 21, so that ventilation and heat dissipation are facilitated, and the heat dissipation efficiency of the electrical box 100 is further enhanced.

The casing 10 is divided into the middle case 11 and the base 12, the first heat dissipation hole 111 is formed at the upper end of the middle case 11, and the second heat dissipation hole 121 is formed at the bottom of the base 12, so that air convection can be conveniently formed between the first heat dissipation hole 111 and the second heat dissipation hole 121. Further, dividing the case 10 into the middle case 11 and the base 12 can facilitate the installation of the reactor 40 in the case 10 and the removal of the reactor 40.

Further, a certain gap is left between the reactor 40 and the middle case 11, which facilitates air convection between the first heat dissipation hole 111 and the second heat dissipation hole 121.

Through making second fixed plate 123 be less than first fixed plate 122 for form certain difference in height between first fixed plate 122 and the ground, thereby can play certain rain-proof water effect. The reactor 40 is fixed to the first fixing plate 122, and the middle case 11 is fixed to the second fixing plate 123.

In addition, the groove 125 facing the reactor 40 is provided at the position of the second heat dissipation hole 121, which can facilitate the air flow flowing into the middle case 11 from the second heat dissipation hole 121 and the water flow to the ground.
