Technical Field

[0001] The present invention relates to the technical field of air conditioners, and more particularly, to an electric control heat dissipation structure and an air conditioner. Background Art

[0002] During the operation of the electric control module of an air conditioner, a large amount of heat is often generated. If the heat is not dissipated in time, it may cause damage to electronic components. In addition, the entry of foreign matters such as condensed water, rainwater, and flying insects into the electric control box will also seriously affect the reliability of the electric control components in the electric control module.

[0003] In the prior art, in order to achieve the heat dissipation of the electric control module, one method is to set heat sinks. This method has a high cost and can only effectively dissipate heat from the electronic components in contact with the heat-conducting material. Another method is to open an opening on the electric control box to allow the heat to dissipate through the opening, but it is difficult to balance the effects of waterproofing and preventing foreign matters, and it may also cause failures of electronic components. Summary of the Invention

[0011] Further, a blower and a guide ring are provided on the blower side, the opening direction of the ventilation opening is parallel to the axial direction of the blower, and is located on the side wall far from the blower; the ventilation opening is parallel to the axial direction of the blower, and it is very difficult for the water radially thrown out during the operation of the blower to be thrown into the ventilation opening.

[0012] Further, the ventilation opening is within the radial range of the two openings of the guide ring; it can further prevent water droplets from being thrown into the electrical side during the operation of the blower, achieving a better waterproof effect.

Detailed implementation manners

[0024] To make the above - mentioned objects, features, and advantages of the present invention more obvious and understandable, the following will describe the specific embodiments of the present invention in detail with reference to the accompanying drawings.

[0025] Embodiment 1:

[0026] As Figure 1 shown, Embodiment 1 of the present invention provides an electric control heat dissipation structure, including an electric control box 100 and a wind separation vertical plate 200, both of which are arranged inside the housing of the outdoor unit of the air conditioner.

[0027] As Figure 4 shown, the electric control box 100 includes a left side plate 110, a main board 120, and a right side plate 130 that are connected in sequence, jointly enclosing a box body with an opening. The inside of the box body is used to install electric control components. Among them, the right side plate 130 is arranged opposite to the left side plate 110. The left side plate 110 is provided with a first heat dissipation hole 111, and the right side plate 130 is provided with a second heat dissipation hole 131. Therefore, the left and right sides of the electric control box 100 are communicated to form a ventilation duct.

[0028] Preferably, the first heat dissipation hole 111 and / or the second heat dissipation hole 131 are one or more rectangular openings. Further referring to Figure 4 , in this embodiment, the first heat dissipation hole 111 includes three small rectangular openings arranged along the length direction, and the second heat dissipation hole 131 is a large rectangular opening. Setting a rectangular opening with a larger area can achieve a better heat dissipation effect; while setting it as multiple small rectangular openings, the structural strength is higher and it is not easy to deform.

[0029] Preferably, reinforcing ribs are provided at the edges of the first heat dissipation hole 111 and / or the second heat dissipation hole 131. Since opening rectangular openings will affect the strength of the electric control box, setting reinforcing ribs at the opening edges can enhance the structural strength of the electric control box.

[0030] Preferably, the left side plate 110 is installed on the air separation vertical plate 200, and the housing is divided into a blower side 20 and an electrical side 10. The blower side 20 is installed with a blower 300, a flow guide ring 200, etc., and the electrical side 10 is used to install electrical control components. The main board 120 of the electrical control box 100 and the right side plate 130 are both located on the electrical side 10.

[0031] Specifically, referring to Figure 3-4 , a hook 112 is provided at the top of the left side plate 110, and a buckle 113 is provided at the bottom. First, the buckle 113 is inserted into the slot 240 of the air separation vertical plate 200, and then the hook 112 is used to hook on the top of the air separation vertical plate 200, so as to install the entire plate body of the left side plate 110 on the air separation vertical plate 200.

[0032] As Figure 2-3 shown, the air separation vertical plate 200 is provided with a through hole 210 corresponding to the first heat dissipation hole 111, and a filter screen 220 is covered on the left side of the through hole 210; it should be noted that the left side here refers to the side facing the blower side 10, and the right side refers to the side facing the electrical side 20.

[0033] Above, on the one hand, by providing the through hole 210 on the air separation vertical plate 200 corresponding to the first heat dissipation hole 111, so that the through hole 210 is communicated with the first heat dissipation hole 111, a heat dissipation air duct can be formed between the blower side 20 and the electrical side 10. When the blower 300 rotates, air flows through the heat dissipation air duct, and the heat dissipation effect on the electrical control components on the electrical side is remarkable; on the other hand, by providing a filter screen on the through hole 210, sundries such as flying insects can be filtered to avoid affecting the normal operation of the unit. Therefore, the electrical control heat dissipation structure of the present invention can simultaneously achieve the effects of heat dissipation and foreign object prevention.

[0034] In addition, the through hole 210 is one or more. In this embodiment, a plurality of through holes 210 are provided. On the one hand, this setting is to maintain the structural strength of the air separation vertical plate 200 and has strong versatility; on the other hand, when the filter screen is deformed or damaged, setting the air guiding part of the air separation vertical plate into a plurality of through holes can also play a secondary protection role.

[0035] Preferably, the through hole 210 extends along the upper right in the cross section of the air separation vertical plate 200 in the thickness direction, that is, the opening of the through hole 210 is higher at the electrical side 20 and lower at the blower side 10. Even if water droplets are blown to the through hole, they will also fall back to the blower side 10 under the action of gravity, playing a certain waterproof effect.

[0036] Preferably, a filter screen pressing plate 230 is covered on the left side of the filter screen 220. The filter screen pressing plate 230 can, on the one hand, press and fix the filter screen 220, and on the other hand, can also achieve the function of waterproofing.

[0037] Specifically, the filter pressing plate 230 is one or more boss structures protruding towards the blower side 20. In the first embodiment, the filter pressing plate 230 is two boss structures arranged along the length direction of the air separation vertical plate 200. A ventilation opening 231 is provided on one side wall of the boss. The filter pressing plate 230 is set as a boss structure and is provided with a ventilation opening 231 to avoid blocking the heat dissipation air duct and maintain the air flow between the blower side and the electrical side.

[0038] As Figure 5 shown, it is the structure of the outdoor unit of the air conditioner provided by the first embodiment of the present invention. The left side plate of the electric control box 100 divides the housing into two parts, that is, the blower side 20 on the left side of the vertical dotted line and the electrical side 10 on the right side. The blower side 20 is provided with a blower 300 and a guide ring 400.

[0039] Preferably, the opening direction of the ventilation opening 231 is parallel to the axial direction of the blower 300 and is located on the side wall of the filter pressing plate 230 far from the blower 300. In this way, it is very difficult for the water (including condensed water and rainwater, etc.) radially thrown out by the blower 300 after rotation to enter the ventilation opening 231.

[0040] Preferably, the guide ring 400 is a circular ring structure, including an upper opening 410 at the top and a lower opening 420 at the bottom. The ventilation opening 231 is within the radial range from the upper opening 410 to the lower opening 420, that is, the ventilation opening 231 is located Figure 5 between the two horizontal dotted lines. Due to the shielding of the guide ring 400, it can further prevent water droplets from being thrown into the electrical side during the operation of the blower, achieving a better waterproof effect.

[0041] In addition, since the filter 220 is a fine mesh structure, on the premise that the filter pressing plate 230 blocks water droplets from entering the ventilation opening 231, the filter 220 can also adsorb water mist to prevent the water mist from entering the electrical side 10, and the waterproof effect is remarkable.

[0042] Embodiment Two:

[0043] As Figure 6 shown, the second embodiment of the present invention provides an electric control heat dissipation structure, including an air separation vertical plate 200 and an electric control box. The electric control box 100 includes a left side plate installed on the air separation vertical plate 200, and a main board 120 and a right side plate 130 connected in sequence. The left side plate is provided with a first heat dissipation hole, and the right side plate 130 is provided with a second heat dissipation hole 131. For a brief description, for the parts not mentioned in this embodiment, reference can be made to the corresponding content in the first embodiment.

[0044] The difference between the second embodiment and the first embodiment is that the filter pressing plate 230 is a single larger boss structure, and the ventilation opening 231 is a larger opening, which can also achieve the function of pressing the filter net 220 and prevent foreign matters such as water and insects from entering the electrical side 10.

[0045] An embodiment of the present invention provides an air conditioner, in which the above-mentioned electric control heat dissipation structure is arranged in the outdoor unit of the air conditioner. On the one hand, the electric control heat dissipation structure forms a heat dissipation air duct, which can achieve the convective heat dissipation effect on the electric control components in the electric control box. On the other hand, it can prevent foreign matters such as water and insects from entering the electric control box and ensure the stable operation of the electric control components.

[0046] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be subject to the scope defined by the claims.
