Abstract

This utility model discloses a reactor box, including a box body disposed on a partition and several heat dissipation holes formed on the box body. The box body is an integral funnel-shaped box body and includes a protective box body section and a current-guiding box body section. The protective box body section is connected to the partition to form a cavity for accommodating the reactor. Several heat dissipation holes are distributed on the vertical sidewalls of the protective box body section. A vent is formed at the bottom of the current-guiding box body section, and the current-guiding box body section is connected to the partition to form a vent cavity. The cross-sectional area of ​​the vent cavity gradually decreases from its upper end to its lower end.

That is, after rainwater enters the box body, the structural design of the current-guiding box body section can quickly drain the rainwater from the vent, thereby reducing the probability of damage to the reactor caused by rainwater entering the reactor box.

Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to a reactor box and its anti-aircraft component heat dissipation component and an air conditioning outdoor unit. Background Technology

[0002] Reactors are typically installed on the electrical control PCB of an air conditioner outdoor unit to improve the performance of the mains power supply and reduce interference to the air conditioner controller. To reduce mutual thermal radiation interference between the reactor and the electrical control components, including the electrical control PCB, which could lead to poor overall heat dissipation of the reactor and affect its performance, the reactor and electrical control components are generally arranged in different cavities. The reactor is usually installed in a reactor box, and the electrical control components are usually installed in an electrical control box. The reactor box and the electrical control box are located on different sides of the partition inside the air conditioner outdoor unit.

[0003] Because the outdoor unit of an air conditioner has gaps, rainwater can enter the unit. In order to ensure good heat dissipation of the reactor box, a certain number of ventilation holes are usually made on the reactor box. However, some ventilation holes are poorly designed, such as being located at the top of the reactor box. In this case, the probability of rainwater entering the reactor box through the ventilation holes is relatively high, and the rainwater is not drained from the reactor box in time. This can lead to a greater chance that the reactor installed in the reactor box will be damaged by rainwater. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a reactor box and its anti-aircraft component, heat dissipation component and air conditioner outdoor unit, so as to solve the problem that in the existing technology, the probability of rainwater entering the reactor box is relatively high and cannot be discharged in time, which leads to a relatively high probability of damage to the reactor assembled in the reactor box.

[0005] To achieve the above objectives, the first aspect of this utility model adopts the following technical solution: a reactor box, which is installed on the partition of an air conditioner outdoor unit, including a box body installed on the partition and a plurality of heat dissipation holes opened on the box body. The box body is an integral funnel-shaped box body and includes a protective box body section and a flow guiding box body section distributed vertically. The protective box body section is connected to the partition to form a cavity for installing the reactor. The plurality of heat dissipation holes are distributed on the vertical sidewall of the protective box body section.

[0006] The bottom end of the flow guide box section has a vent, and the flow guide box section is connected to the partition to form a vent cavity. The cross-sectional area of ​​the vent cavity gradually decreases from its upper end to its lower end.

[0007] The second aspect of this utility model adopts the following technical solution: an anti-aircraft component protection and heat dissipation component, which is installed inside the casing of the outdoor unit of the air conditioner, including a partition, an electrical control box installed on one side of the partition and used to provide installation space for the electrical control component, and a reactor box as described in the first aspect of this utility model installed on the other side of the partition.

[0008] The third aspect of this utility model adopts the following technical solution: an air conditioner outdoor unit, including an anti-air component protective heat dissipation component as described in the second aspect of this utility model.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] This reactor box uses several heat dissipation holes and vents to provide the reactors installed inside with excellent heat dissipation capabilities. At the same time, the arrangement of these heat dissipation holes and vents greatly reduces the chance of rainwater entering the box. Even if rainwater does enter the box, the structural design of the guide box section can quickly drain the rainwater through the vents, thereby reducing the chance of damage to the reactor caused by rainwater entering the reactor box.

[0022] Reactor 4. Detailed Implementation

[0023] The present invention will be further described in detail below through specific embodiments:

[0024] Because the existing heat dissipation holes 21 on the reactor box are poorly designed, for example, if the heat dissipation holes 21 are located at the top of the reactor box, the probability of rainwater entering the reactor box through the heat dissipation holes 21 is relatively high, and the rainwater is not drained out of the reactor box in time. This will increase the likelihood of the reactor 4 installed inside the reactor box being damaged by rainwater. To solve this problem, such as... Figure 1 , Figure 6 as well as Figure 7 As shown, this utility model embodiment proposes a reactor box, which is installed on the partition 1 of the outdoor unit of an air conditioner. It includes a box body 2 installed on the partition 1 and a plurality of heat dissipation holes 21 opened on the box body 2. The box body 2 is an integral funnel-shaped box body 2 and includes a protective box body 2 section and a flow guiding box body 2 section distributed vertically. The protective box body 2 section is connected to the partition 1 to form a cavity for installing the reactor 4. The plurality of heat dissipation holes 21 are distributed on the vertical sidewall of the protective box body 2 section. The bottom end of the flow guiding box body 2 section forms a vent 24 and the flow guiding box body 2 section is connected to the partition 1 to form a vent cavity. The cross-sectional area of ​​the vent cavity gradually decreases from its upper end to its lower end.

[0025] This reactor box uses several heat dissipation holes 21 and vents 24 to provide the reactor 4 installed inside with better heat dissipation capabilities. At the same time, the arrangement of the heat dissipation holes 21 and vents 24 greatly reduces the probability of rainwater entering the box 2. That is, after rainwater enters the box 2, the structural design of the guide box 2 section can quickly guide the rainwater out through the vents 24, thereby reducing the probability of the reactor 4 being damaged due to rainwater entering the reactor box.

[0026] The heat dissipation area of ​​the heat dissipation zone formed by the plurality of heat dissipation holes 21 is larger than the heat dissipation area of ​​the vent 24, and as the main heat dissipation channel, it has a good heat dissipation effect.

[0027] In this embodiment, the flow guide box section 2 has a flow guide inclined wall 231 located below the bottom opening of the protective box section 2 and used to receive and guide rainwater.

[0028] Specifically, the protective box section 2 is square, and the guide box section 2 is a cone formed by tilting one side wall of the square cylinder. If rainwater enters the protective box section 2 through several heat dissipation holes 21, the rainwater flows downward under the action of gravity to the receiving guide inclined wall 231, and then is quickly discharged from the vent 24 through the receiving guide inclined wall 231.

[0029] To further improve the protective performance of the box body 2, the bottom end of the flow guide box body 2 extends downward to form an extended box body 2 section, and a first ventilation grille 26 is formed inside the extended box body 2 section.

[0030] In this embodiment, the bottom end of the guide box 2 extends downward to form an extended box 2 section, so that the vent 24 is moved to the bottom end of the extended box 2 section. The first vent grille 26 protects the bottom of the box 2 and allows the incoming rainwater to be discharged in time.

[0031] Here, the extended box section 2 is also square, which facilitates the installation of the first ventilation grille 26.

[0032] Based on the above, the bottom end of the second section of the extended box is cut with an inclined surface to form a liquid-draining inclined surface 251, so that the bottom end of the second section of the extended box is pointed, which plays a role in guiding the rainwater flowing to this point; if the bottom end of the second section of the extended box is designed as a flat surface, due to the surface tension of the rainwater, the rainwater will hang at the vent 24 and then accumulate upward into the first vent grille 26, affecting the rainwater discharge capacity.

[0033] Specifically, the lowest point of the extended box section 2 is attached to the partition 1.

[0034] In order to stably connect the reactor box to the partition 1, a plurality of first buckles 27 are formed on the protective box body 2 section, and a plurality of first slots 11 are opened on the partition 1, and the plurality of first buckles 27 are engaged in a corresponding manner with the plurality of first slots 11.

[0035] Here are some specific examples:

[0036] Two spaced first buckles 27 are formed on the left side of the protective box section 2 along the vertical direction, and two spaced first buckles 27 are formed on the right side of the protective box section 2 along the vertical direction, so that four first buckles 27 are formed on the protective box section 2. The four first buckles 27 are inserted one by one into the four first slots 11 on the partition 1 to complete the connection between the reactor box and the partition 1.

[0037] To further improve the connection stability of the reactor box, the side wall of the extended box section 2 is provided with a second fixing hole 252 for alignment with the first fixing hole on the partition 1 and connection and fixation by a locking device. Here, the locking device can be a screw, which is screwed into the first fixing hole and the second fixing hole 252 to further fix the connection between the reactor box and the partition 1.

[0038] The reactor box described in the above embodiments is applied to the heat dissipation and protection components of the anti-aircraft assembly, such as... Figures 1-5 As shown, according to another embodiment of the present invention, the anti-aircraft component protection and heat dissipation component is disposed inside the casing of the air conditioner outdoor unit, including a partition 1, an electrical control box 3 disposed on one side of the partition 1 and used to provide installation space for the electrical control component, and a reactor box disposed on the other side of the partition 1 as described in the above embodiment.

[0039] In this embodiment, the partition 1 separates the reactor box and the control box 3. The control box 3 has an assembly groove 16 on its front side, in which the control components are installed. The reactor 4 is installed in the reactor box, so that the control components and the reactor 4 are arranged separately, thereby achieving isolation, improving heat dissipation, and improving equipment performance.

[0040] The partition 1 has an assembly area for installing the reactor 4 on one side. The partition 1 has a wire hole 12 located below the assembly area for the connection between the reactor 4 and the electrical control components to pass through. The box 2 covers the wire hole 12. The box 2 can wrap the entire assembly area, improving the overall containment and protection of the reactor 4.

[0041] To ensure that the reactor 4 has sufficient stability and better heat dissipation, the assembly area is provided with multiple connecting protrusions 13. The assembly plate of the reactor 4 is connected and fixed to each connecting protrusion 13 by connectors. The assembly area is also provided with a second ventilation grille 14 and a reinforcing protrusion 15 for abutting against the reactor 4.

[0042] In this embodiment, there are four connecting protrusions 13 arranged in an array. The reinforcing protrusions 15 are arranged in a long strip between the two upper connecting protrusions 13 and the two lower connecting protrusions 13. There are two second ventilation grilles 14, which are distributed between the two upper connecting protrusions 13 and the two lower connecting protrusions 13, in order to improve the assembly stability of the reactor 4, improve the structural strength of the partition 1, and also facilitate heat dissipation.

[0043] The connecting component can be a bolt.

[0044] To ensure sufficient assembly stability of the electrical control box 3, one side of the back plate 31 on the rear side of the electrical control box 3 is detachably connected to the partition plate 1 and the other side is detachably connected to the housing.

[0045] The partition 1 has an assembly groove 16 on its top side and a second buckle 17 on its lower side. The back plate 31 extends to one side from its left end to form a left end extension for attaching to the partition 1. The left end extension is provided with a hook 32 for attaching to the assembly groove 16 and a second slot 33 for the second buckle 17 to engage.

[0046] The back plate 31 extends to one side to form a right end extension, and the right end extension is detachably connected to a terminal plate 34. The terminal plate 34 is attached to the inner wall of the housing and is detachably connected.

[0047] The specific installation procedure for electrical control box 3 is as follows:

[0048] First, the hook 32 on the left end extension of the back plate 31 of the electrical control box 3 is attached to the mounting groove 16 on the partition plate 1 for connection and fixation, and can also be reinforced by screws. At the same time, the second buckle 17 is inserted into the second slot 33 for connection and fixation.

[0049] Then, the right end extension of the back plate 31 is fixedly connected to the terminal plate 34 with bolts, and then the terminal plate 34 is fixedly connected to the inner wall of the housing with bolts to complete the installation of the electrical control box 3; this assembly process is convenient.

[0050] The anti-aircraft component and heat dissipation component described in the above embodiments are applied to the outdoor unit of an air conditioner, such as... Figure 1 As shown, according to another embodiment of the present invention, the air conditioner outdoor unit includes a casing, an anti-air component protection and heat dissipation component as described in the above embodiment disposed inside the casing, and other existing structures, so that the air conditioner outdoor unit has the advantages of the above-mentioned anti-air component protection and heat dissipation component, and the rainwater discharged from the vent 24 falls onto the chassis provided at the bottom of the casing and is collected by the drainage channel before being discharged.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
