Detailed Description

Reference will now be made in detail to embodiments of the present utility model, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

A reactance box 1, an air conditioner outdoor unit, and an air conditioner according to an embodiment of the present utility model are described below with reference to fig. 1 to 6.

As shown in fig. 2 to 6, the reactance box 1 according to the embodiment of the present utility model includes: a box 11 and a water deflector 12. The box 11 is internally provided with a containing cavity 111 for installing the reactor 2, the box 11 is provided with a first radiating hole 1133 and a drain hole 1134, and the first radiating hole 1133 and the drain hole 1134 are communicated with the containing cavity 111. The water blocking member 12 is disposed in the accommodating cavity 111, the water blocking member 12 and the inner wall of the box 11 define a drain channel 121, at least a portion of the first heat dissipation holes 1133 are opposite to the drain channel 121, and the drain holes 1134 are communicated with the drain channel 121 and are disposed adjacent to the bottom of the drain channel 121.

According to the reactance box 1 of the embodiment of the present utility model, heat generated when the reactor 2 operates can be discharged through the first heat dissipation hole 1133 on the box body 11, when external water drops splash into the accommodating chamber 111 through the first heat dissipation hole 1133, since the first heat dissipation hole 1133 is opposite to the water drain passage 121 and the water drain hole 1134 communicates with the water drain passage 121, the water drops can fall into the water drain passage 121 and be discharged outside the box body 11 through the water drain hole 1134. Therefore, the reactor 1 of the embodiment of the utility model can meet the heat dissipation requirement of the reactor 2, and has better waterproof effect.

In the embodiment of the present application, as shown in fig. 2 and 3, the first heat dissipation holes 1133 are opposite to the water drain channel 121, so that the water drops entering the accommodating cavity 111 through the first heat dissipation holes 1133 can all fall into the water drain channel 121, thereby improving the waterproof effect of the reactance box 1.

Specifically, as shown in fig. 2 and 3, the box 11 includes a top plate 112 and a side plate 113, the top plate 112 is disposed at an upper end of the side plate 113 and defines a receiving cavity 111 with the side plate 113, one side (lower side) of the water blocking member 12 is connected to the side plate 113, the other side (upper side) of the water blocking member 12 extends toward the top plate 112, a drain hole 1134 is disposed on the side plate 113, and a first heat dissipation hole 1133 is disposed on at least one of the top plate 112 and the side plate 113. It can be understood that, when the first heat dissipation hole 1133 is disposed on the top plate 112, the projection of the first heat dissipation hole 1133 perpendicular to the up-down direction of the case 11 is located in the water drain channel 121; when the first heat dissipation hole 1133 is provided on the side plate 113, a projection of the first heat dissipation hole 1133 in a right-left direction orthogonal to the case 11 is located in the drainage channel 121.

In an example, as shown in fig. 2 and 3, the first heat radiation holes 1133 are provided only on the side plate 113, because the inventor found through experimental study that when the first heat radiation holes 1133 are provided on the top plate 112, water droplets are easily splashed into the accommodation chamber 111. The first heat dissipation holes 1133 are only arranged on the side plates 113, so that the heat dissipation effect of the reactance box 1 is not affected, the probability that water drops splash into the accommodating cavity 111 can be reduced, and the waterproof effect is good.

As shown in fig. 2, the first heat dissipation holes 1133 are provided on the side plate 113 above the drain holes 1134, and the first heat dissipation holes 1133 are arranged adjacent to the top plate 112, so that the heat dissipation effect of the reactance box 1 can be improved.

Alternatively, as shown in fig. 5 and 6, the first heat dissipation holes 1133 are plural, and the plural first heat dissipation holes 1133 are arranged at intervals in the up-down direction of the side plate 113. In an example, the drain passage 121 and the plurality of first heat dissipation holes 1133 each extend along the length direction (front-rear direction in fig. 5) of the water deflector 12, whereby the heat dissipation effect of the reactance case 1 can be further improved.

Alternatively, as shown in fig. 2 and 3, the height of the first heat radiation hole 1133 is not higher than the upper edge of the water deflector 12, whereby it is possible to prevent water droplets splashed by the first heat radiation hole 1133 to the housing chamber 111 from falling out of the water discharge passage 121, to improve the water-proof performance of the reactance case 1.

Alternatively, as shown in fig. 3 and 5, the side plate 113 includes an upper plate portion 11311 and a lower plate portion 11312, the upper plate portion 11311 is disposed at an upper end of the lower plate portion 11312 and is connected to the top plate 112, the upper plate portion 11311 and the lower plate portion 11312 are spaced apart to define a drain hole 1134, a lower side of the water blocking member 12 is connected to the lower plate portion 11312, and the first heat dissipation hole 1133 is disposed at the upper plate portion 11311. It is understood that the upper plate portion 11311 and the lower plate portion 11312 may be manufactured separately and then spliced together.

In one example, as shown in fig. 3 and 5, the top plate 112 is integrally formed with the upper plate portion 11311, and the water deflector 12 is integrally formed with the lower plate portion 11312. It can be understood that the reactance box 1 is formed by bending sheet metal, the top plate 112 and the upper plate portion 11311 are formed as an integral sheet metal part, and the water blocking member 12 and the lower plate portion 11312 are formed as an integral sheet metal part, so as to facilitate the processing and manufacturing of the reactance box 1.

In some embodiments, as shown in fig. 3, the water deflector 12 includes an inclined portion 122 and an extension portion 123, the lower side of the inclined portion 122 is connected to the side plate 113, the upper side of the inclined portion 122 extends obliquely toward a direction away from the first heat radiation hole 1133 and is connected to the extension portion 123, and the upper side of the extension portion 123 extends toward the direction of the top plate 112 and is spaced apart from the inner wall surface of the top plate 112. It will be appreciated that the drain channel 121 is generally funnel-shaped in a projection orthogonal to the length direction of the case 11, and the drain hole 1134 is disposed adjacent to the lower end of the inclined portion 122, so that water in the drain channel 121 can be drained, and the drain efficiency is high.

In addition, since the upper side of the extension 123 extends in the direction of the top plate 112 and is spaced apart from the inner wall surface of the top plate 112, the probability of water droplets splashing outside the drain passage 121 can be reduced, the heat dissipation of the reactance box 1 is not affected, and the space occupied by the accommodation chamber 111 is small.

Alternatively, as shown in fig. 5 and 6, the side plates 113 include two first side plates 1131 and two second side plates 1132, the two first side plates 1131 are arranged at intervals along the width direction (left-right direction in fig. 2) of the accommodating cavity 111, the two second side plates 1132 are arranged at intervals along the length direction of the accommodating cavity 111, the top plate 112, the first side plates 1131 and the second side plates 1132 define the accommodating cavity 111, the first heat dissipation holes 1133 and the drain holes 1134 are all arranged on the first side plates 1131, and the second side plates 1132 are provided with the second heat dissipation holes 1135. It is understood that the second heat radiation holes 1135 are provided on the side plates 113 (second side plates 1132) arranged at intervals along the length direction of the accommodation chamber 111, whereby the heat radiation effect of the reactance box 1 can be further improved.

Specifically, as shown in fig. 2, 3, 5 and 6, the upper edge outside the first heat dissipation hole 1133 is provided with a first shielding edge 1136, and the first shielding edge 1136 extends obliquely downward toward a direction away from the first heat dissipation hole 1133. The upper edge outside the second heat dissipation hole 1135 is provided with a second shielding edge 1137, and the second shielding edge 1137 extends downwards in an inclined way towards the direction away from the second heat dissipation hole 1135. It can be appreciated that the first shielding edge 1136 may downwardly dispose the outer port of the first heat dissipation hole 1133, and the second shielding edge 1137 may downwardly dispose the outer port of the second heat dissipation hole 1135, so that the probability that water drops splash to the accommodating cavity 111 through the first heat dissipation hole 1133 and the second heat dissipation hole 1135 may be reduced, and the waterproof performance of the reactance box 1 may be improved.

In an example, the first heat dissipation hole 1133 and the second heat dissipation hole 1135 may be formed by stamping, and the first shielding edge 1136 and the second shielding edge 1137 may be formed at the same time during stamping, so that the production cost of the reactance box 1 may be reduced, and the waterproof performance of the reactance box 1 may be improved.

Optionally, as shown in fig. 4, the reactance box 1 further includes a base 13, the base 13 is mounted at the lower end of the box body 11, and a heat dissipation gap (not shown) is provided between the base 13 and the side plate 113, and the heat dissipation gap communicates with the accommodating cavity 111. It can be understood that cold air flows into the accommodating chamber 111 from the heat dissipation gap between the base 13 and the side plate 113 as shown by the arrow in fig. 2, then takes away heat on the surface of the reactor 2 to form hot air and rises, and then is discharged out of the reactor case 1 through the first heat dissipation hole 1133 and the second heat dissipation hole 1135 to take away heat from the surface of the reactor 2, thereby achieving the effect of cooling the reactor 2.

In some embodiments, at least one of the first heat dissipation holes 1133, the second heat dissipation holes 1135, the drain holes 1134, and the heat dissipation gap has a width of 3 millimeters or less. In the embodiment of the application, the first heat dissipation hole 1133, the second heat dissipation hole 1135, the water drain hole 1134 and the heat dissipation gap are all smaller than or equal to 3 millimeters, so that the probability that mosquitoes enter the accommodating cavity 111 can be effectively prevented, and the working reliability of the reactor 2 is improved.

Optionally, as shown in fig. 5, a routing hole 1138 is provided on the second side plate 1132, and the routing hole 1138 communicates with the accommodating cavity 111, so as to introduce the circuit of the reactor 2 to the outside of the case 11 through the routing hole 1138.

According to the outdoor unit of the air conditioner of the embodiment of the present utility model, heat generated when the reactor 2 operates can be discharged through the first heat dissipation hole 1133 on the case 11, and when external water drops splash into the receiving chamber 111 through the first heat dissipation hole 1133, since the first heat dissipation hole 1133 is opposite to the water drain passage 121 and the water drain hole 1134 communicates with the water drain passage 121, the water drops can drop into the water drain passage 121 and be discharged outside the case 11 through the water drain hole 1134. Therefore, the reactance box 1 of the outdoor unit of the air conditioner can meet the heat dissipation requirement of the reactor 2, and has good waterproof effect.

Specifically, as shown in fig. 1, the outdoor unit 3 has a fan chamber 31, the outdoor unit further includes a partition 5, the partition 5 is disposed in the outdoor unit 3 and defines the fan chamber 31 and a compressor chamber 32, the reactance box 1 is disposed at the bottom of the fan chamber 31 and spaced apart from the partition 5, and the first heat dissipation hole 1133 is opposite to the partition 5. The air condensing units still includes fan subassembly 4, and fan subassembly 4 locates in the fan chamber 31, and reactance box 1 is located the bottom in fan chamber 31, and fan subassembly 4 includes fan 41, and the axial of fan 41 is arranged with the length direction parallel of box body 11.

It will be appreciated that, as shown in fig. 1, the water droplets thrown out by the fan 41 will splash onto the partition 5, then reflect onto the side plate 113 of the reactance box 1 adjacent to the partition 5, and pass through the first heat dissipation hole 1133 to enter the accommodating cavity 111, so that the water can be stopped in the water drain channel 121 by the action of the water stop 12, and finally be discharged to the outside through the water drain hole 1134.
