In order that the above objects, features and advantages of the present disclosure may be more clearly understood, a further description of aspects of the present disclosure will be provided below. It should be noted that, without conflict, the embodiments of the present disclosure and features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the disclosure.
In order to realize heat dissipation of the electric control box of the air conditioner, the prior art generally adopts a technical scheme of forming heat dissipation holes, but the inventor discovers that the scheme can bring influence on the waterproof performance of the electric control box and cannot meet the requirements of both waterproof and heat dissipation.
Based on this, the embodiment of the disclosure provides an air conditioner, which provides a structure capable of completing heat dissipation and meeting waterproof requirements for an air conditioner electric control box, thereby meeting performance requirements of the air conditioner in different working conditions and working scenes.
The air conditioner will be described in detail by specific examples:
referring to fig. 1 to 7, the present embodiment provides an air conditioner including an electric control box 1, a coaming plate 2, a water baffle 3, and a fan 4. The electric control box 1 is connected with the coaming 2, the electric control box 1 is provided with electric control box radiating holes 5, the electric control box radiating holes 5 are used for realizing air communication between the inside and the outside of the electric control box 1, so that the heat exchange efficiency between the inside and the outside of the electric control box 1 is quickened, and the heat emitted by the internal components of the electric control box 1 can be timely conducted to the outside of the electric control box 1 through the electric control box radiating holes 5; the coaming 2 is provided with coaming radiating holes 6, and the coaming radiating holes 6 are used for realizing the communication of air at two sides of the coaming radiating holes 6, so that heat transmitted by the electric control box 1 can be further transmitted in time. The breakwater 3 sets up in the one side of bounding wall 2 dorsad automatically controlled box 1 and corresponds with the position of bounding wall louvre 6, if along on the direction of perpendicular to bounding wall 2, at least partial breakwater 3 shelters from bounding wall louvre 6 to prevent outdoor rainwater or drop of water through bounding wall louvre 6, through the breakwater 3 to the manger plate effect of bounding wall louvre 6, ensure that outdoor rainwater or drop of water can not get into automatically controlled box 1 through bounding wall louvre 6 and automatically controlled box louvre 5, and then avoided the influence of rainwater or drop of water to the inside components and parts normal work of automatically controlled box 1. The heat dissipation runner 7 is formed between the water baffle 3 and the coaming 2, the fan 4 is arranged on one side of the coaming 2, which is opposite to the electric control box 1, a heat dissipation area is formed between one side of the fan 4, which faces the coaming 2, and the coaming 2, when the fan 4 works, the heat dissipation area can become a heat dissipation negative pressure area, and referring to an arrow shown near the fan in fig. 6, the flow direction of air when the fan works is shown, and the heat dissipation negative pressure area formed by the fan 4 can timely suck hot air and emit the hot air to the outside of the air conditioner through the fan 4. The breakwater 3 is located one side of the coaming 2 towards the fan 4, and the heat dissipation port of the heat dissipation flow channel 7 is communicated with a heat dissipation area, namely, heat dissipated by internal components of the electric control box 1 is conducted to the heat dissipation flow channel 7 through the heat dissipation holes 5 and the coaming heat dissipation holes 6 of the electric control box and then is absorbed by a heat dissipation negative pressure area formed by the fan 4 and dissipated through the fan 4, that is, a structure capable of completing heat dissipation and meeting waterproof requirements is provided for the electric control box 1, so that performance requirements of the air conditioner in different working conditions and working scenes are met.
The electric control box in this embodiment may also be other electrical components with heat dissipation requirements and waterproof requirements, and meanwhile, the air conditioner in this embodiment may be a window air conditioner, a hanging air conditioner, or a vertical air conditioner, so long as the air conditioner is equipped with electrical components with heat dissipation and waterproof requirements, and the type and model of the air conditioner are not limited.
In some embodiments, on the projection plane perpendicular to the direction of the coaming 2, the projections of the electric control box heat dissipation holes 5 and the projections of the coaming heat dissipation holes 6 are arranged at intervals, that is, the electric control box heat dissipation holes 5 and the coaming heat dissipation holes 6 are staggered, so that even if rainwater or water drops enter the area of the electric control box 1 through the coaming heat dissipation holes 6, the rainwater or water drops cannot enter the electric control box 1 directly through the electric control box heat dissipation holes 5, and the purpose of further blocking the rainwater or the water drops from entering the electric control box 1 is achieved.
With continued reference to fig. 2, 3,4, 6 and 7, the electronic control box 1 includes an electronic control box body 11 and an electronic control box cover 12, and it is understood that the electronic control box 1 includes the electronic control box body 11 and the electronic control box cover 12 for the purpose of facilitating maintenance and replacement of components inside the electronic control box 1, and in other embodiments, the electronic control box 1 may be integrally designed. The coaming 2 comprises a coaming 21 and a side coaming 22 which is connected with the coaming 21 in an L shape, wherein the side coaming 22 is provided with an electric control box accommodating opening for accommodating the electric control box main body 11 and a plurality of electric control box mounting holes arranged around the electric control box accommodating opening, and the electric control box main body 11 and/or the electric control box cover 12 are provided with connecting holes corresponding to the electric control box mounting holes. In some embodiments, the electric control box main body 11 is inserted into the electric control box accommodating opening along the direction from one side of the side wall plate 22 away from the front wall plate 21 to the other side of the side wall plate 22 towards one side of the front wall plate 21, the connecting hole on the electric control box main body 11 is connected with the electric control box mounting hole on the side wall plate 22 through a screw, the electric control box cover 12 is mounted on the electric control box main body 11 in a covering manner on one side of the side wall plate 22 away from the front wall plate 21, and further, the connecting hole on the electric control box cover 12 can be connected with the electric control box mounting hole on the side wall plate 22 through a screw. The mounting method has the advantages that when the internal components of the electric control box 1 need to be overhauled and replaced, the overhauling and replacing can be realized only by opening the cover plate, and the side coaming plate 22 does not need to be disassembled. In other embodiments, the main body 11 of the electronic control box is mounted on the electronic control box cover 12, and the electronic control box cover 12 is connected to the side wall 22 through the mounting hole of the electronic control box, and this mounting method has the advantage of facilitating the whole disassembly and replacement of the electronic control box 1. In other embodiments, the side wall 22 is not provided with any mounting holes, and the electronic control box 1 or the electronic control box 11 is directly mounted on the side wall 22, and in particular, in some embodiments, the electronic control box 1 is directly connected with the front wall 21. It should be noted that, in some embodiments, a fixed side wall plate connected in an L-shape with the front wall plate 21 is further provided at an end of the front wall plate 21 away from the side wall plate 22 (i.e., an end away from the electronic control box 1), and the fixed side wall plate is used for connecting the front wall plate 21 and is to be connected with an air conditioner to enhance stability of the wall plate 2.
Specifically, in some embodiments, referring to fig. 7, the electric control box heat dissipation hole 5 includes a first heat dissipation hole 51 disposed on a side wall of the electric control box main body 11 near the front panel 21, the first heat dissipation hole 51 and the panel heat dissipation hole 6 are arranged in a staggered manner, a gap is reserved between the electric control box main body 11 and the front panel 21, and the first heat dissipation hole 51 and the panel heat dissipation hole 6 are communicated to form a first heat dissipation channel 71, and the first heat dissipation channel 71 is communicated with the heat dissipation channel 7 through the panel heat dissipation hole 6. During specific operation, the convection heat exchange between the gas inside the electric control box 1 heated by the operation of the components inside the electric control box 1 and the gas inside the first heat dissipation channel 71 is realized through the first heat dissipation holes 51, and then the convection heat exchange between the gas inside the electric control box 1 and the gas at the heat dissipation channel 7 is realized through the coaming heat dissipation holes 6, and the heat dissipation inside the electric control box 1 is accelerated through the direct heat convection between the gases. In addition, the dislocation setting of the first radiating holes 51 and the coaming radiating holes 6 is beneficial to the improvement of the waterproof performance of the electric control box 1, and in the worst case, when outdoor rainwater or water drops enter the peripheral area of the electric control box 1 enclosed by the coaming 2 through the coaming radiating holes 6, the dislocation setting can avoid the rainwater or water drops to directly enter the electric control box 1 through the first radiating holes 51, so that the damage of the water drops to the internal components of the electric control box 1 is avoided when the situation occurs. It should be noted that, the first heat dissipation channel 71 is configured to facilitate heat dissipation from the electronic control box 1, and prevent the electronic control box body 11 from directly contacting the front wall plate 21 near a side wall of the front wall plate 21 to form a capillary phenomenon to cause water droplets to remain.
With continued reference to fig. 2,6 and 7, in some specific embodiments, the air conditioner includes a duct scroll 41 located on a side of the dash panel 21 facing the electronic control box 1, and a gap is reserved between the electronic control box body 11 and the duct scroll 41 in a direction of a side of the electronic control box body 11 away from the dash panel 21 and a direction of a side of the electronic control box body 11 away from the electronic control box cover 12 to form a second heat dissipation channel 72. Correspondingly, the electric control box radiating hole 5 further comprises a second radiating hole 52 arranged on one side wall of the electric control box main body 11 far away from the front coaming 21, the second radiating hole 52 is communicated with the coaming radiating hole 6 through a second radiating channel 72, and the coaming radiating hole 6 is opposite to the second radiating channel 72. It can be understood that the second heat dissipation holes 52 are used for communicating the gas inside the electric control box 1 with the gas inside the second heat dissipation channel 72, so as to realize the heat convection between the gas inside the electric control box 1 and the gas inside the second heat dissipation channel 72, and further enhance the heat dissipation effect of the electric control box 1. The coaming radiating holes 6 are arranged opposite to the second radiating channels 72, and have the beneficial effects that: on the one hand, the efficiency of convection heat exchange between the gas in the second heat dissipation channel 72 and the gas at the heat dissipation channel 7 is improved, and on the other hand, the direct influence on the electric control box 1 caused by outdoor rainwater or water drops after passing through the coaming heat dissipation holes 6 under the most adverse condition is avoided.
In particular, in some specific embodiments, since the side of the electronic control box body 11 away from the dash panel 21 is less likely to be affected by water droplets, the side of the electronic control box body 11 away from the dash panel 21 is provided with a heat radiation port 54, which is located at a lower portion of the electronic control box body 11, and the second heat radiation hole 52 is located at an upper portion of the electronic control box body 11. That is, according to the actual working situation, under the condition of meeting the waterproof performance requirement or the index requirement, the electric control box main body can be additionally provided with heat dissipation ports with other shapes and numbers, and the present disclosure is not limited to this.
With continued reference to fig. 1 and 6, in some embodiments, the air conditioner includes an air conditioner external case 8, and the electronic control box 1, the coaming 2, the water baffle 3 and the fan 4 are all located in the air conditioner external case 8, and an air inlet channel 9 is formed between the air conditioner external case 8 and the fan 4, where the water baffle 3 is opposite to the air inlet channel 9. The direction of the incoming and outgoing air is indicated with reference to the arrows shown in fig. 1. It will be appreciated that, because there is an integral package of the air conditioner by the air conditioner external case 8, rainwater or water drops mainly affect the electric control box 1 through the air inlet channel 9, and thus the purpose of the water baffle 3 arranged opposite to the air inlet channel 9 is to block the rainwater or water drops coming from the path.
Illustratively, the water baffle 3 includes a water baffle portion 31 facing the air intake passage 9 and upper and lower connection portions 32 (i.e., upper and lower connection portions) connected at a predetermined angle to the water baffle portion 31, and the water baffle 3 is connected to the dash panel 21 through the upper and lower connection portions 32. Through setting up upper and lower connecting portion 32, realized that breakwater 3 is to the epaxial protection of passageway louvre 6 in vertical, further improved the waterproof performance to automatically controlled box 1.
In concrete implementation, a side surface of the water baffle 3, which is close to the air conditioner external box 8, is in extrusion sealing with the air conditioner external box 8 through soft connection, for example, extrusion sealing is realized by arranging soft materials such as a sealing rubber pad at the extrusion sealing position of the water baffle 3 and the air conditioner external box 8, and a heat dissipation opening is arranged on one side of the water baffle 3, which is close to the fan 4, so that the heat dissipation flow channel 7 is communicated with a heat dissipation area. It can be appreciated that the beneficial effect of the water baffle 3 being close to one side of the air conditioner external box 8 and being sealed by extrusion with the air conditioner external box 8 through soft connection is that: through the extrusion seal of breakwater 3 and air conditioner outer box 8, make breakwater 3 just to forming a complete partition wall in the direction of air inlet channel 9, can effectively block the rainwater that blows in or inhale from air inlet channel 9 and enter into heat dissipation runner 7 through the clearance between breakwater 3 and air conditioner outer box 8, and then get into automatically controlled box 1. On the other hand, the water baffle 3 is provided with a heat dissipation opening on one side close to the fan 4 for enabling the heat dissipation flow channel 7 to be communicated with the heat dissipation area, so that hot air at the heat dissipation flow channel 7 is directly dissipated by the fan 4 through the heat dissipation area, and the shape and the position of the heat dissipation opening can be adaptively set according to the working condition of equipment, and the heat dissipation opening is not particularly limited.
Since the fan 4 needs to be fed from the air inlet channel 9 during operation, based on the air movement track in the air inlet channel 9, in some embodiments, referring to fig. 2, the water blocking portion 31 is bent to a preset angle toward the dash panel 21 on a side close to the fan 4, the dash panel heat dissipation hole 6 is disposed at an upper portion of the dash panel 21, and the water blocking portion 31 is narrowed in a direction away from the fan 4 at a position lower than a preset height of a lower edge of the dash panel heat dissipation hole 6. It should be noted that, the advantage of the water blocking portion 31 bending a set angle to the dash panel 21 at the side close to the fan 4 is that: on one hand, the air inlet efficiency of the air inlet channel 9 is improved, and the working efficiency and the heat exchange efficiency of the fan are further improved; on the other hand, the probability of rainwater or water drops entering the heat dissipation flow channel 7 is reduced; on the other hand, the water blocking part 31 is bent to a set angle towards the front coaming plate 21 at one side close to the fan 4, so that the movement speed of the hot air at the heat dissipation opening of the heat dissipation flow channel 7 is increased, and the Bernoulli effect is utilized, so that the heat dissipation speed of the hot air of the heat dissipation flow channel 7 can be greatly increased. The bulkhead heat dissipation holes 6 are provided at the upper portion of the dash panel 21, which is advantageous in that: on the one hand, the upward movement characteristic of the hot air can effectively accelerate the heat dissipation of the hot air in the first heat dissipation channel 71 and the second heat dissipation channel 72; on the other hand, the upper part is provided with a heat dissipation device which can prevent accumulated water of rainwater in extreme weather from entering the first heat dissipation channel 71 and the second heat dissipation channel 72 through the coaming heat dissipation holes 6. Meanwhile, the water blocking portion 31 narrows in a direction away from the fan 4 at a position lower than the lower edge of the coaming heat radiation hole 6 by a preset height for the purpose of: on the premise of ensuring that hot air emitted by the coaming radiating holes 6 is further emitted out through the radiating channels 7, the air inlet efficiency and the air inlet speed of the air inlet channels 9 are improved, so that the radiating efficiency of the fan 4 is improved, and the Bernoulli effect is utilized to further accelerate the radiating rate of the hot air in the radiating channels 7. Of course, according to the actual working condition of the equipment and the working condition requirement, the angle of bending the water blocking portion 31 towards the front coaming 21 at one side close to the fan 4, the height of the coaming heat dissipation holes 6 arranged at the front coaming 21, the narrow height of the water blocking portion 31 and the narrow dimension of the water blocking portion 31 can be adaptively adjusted, and the present disclosure does not limit the present disclosure.
