[0002] The electric control box is a container for placing circuit boards in the air conditioner outdoor unit, and is a very important device. For example, in the Chinese utility model patent with the announcement number CN112066533A and the name of an air conditioner electric control box, the holes of the heat dissipation grid are directly opened on the board layer of the sound insulation board. Although there is a heat dissipation effect, when the air conditioner outdoor unit is flooded with water on rainy days, the water will drip from top to bottom, and it is very likely to drip into the holes of the heat dissipation grid, and finally run onto the PCB board, causing the PCB board to burn or malfunction. At the same time, since the heat dissipation grid is integrated on the sound insulation board, it is necessary to perform hole drilling processing on the sound insulation board separately. Due to the large size of the sound insulation board, it is inconvenient to process and transfer. Utility Model Content

[0024] In order to make the purpose, technical solution and beneficial effects of the utility model more clear, the technical solution of the utility model is further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] See also Figures 1 to 4 The embodiment of the utility model proposes an installation structure of an external machine housing and an electric control box, including:

[0026] The outer casing has a main compartment 1 and a secondary compartment 2 which are connected to each other;

[0027] The electric control box includes a heat dissipation waterproof box 3 and an assembly box 4 connected to each other. The heat dissipation waterproof box 3 and the assembly box 4 are respectively located in the main compartment 1 and the auxiliary compartment 2, and a plurality of heat dissipation grilles 5 are arranged at intervals at the connection between the two. The heat dissipation waterproof box 3 has a connected vent 6 and a ventilation cavity 7. The vent 6 is arranged downward and forms a heat dissipation channel through the ventilation cavity 7 and the heat dissipation grille 5.

[0028] In this embodiment, the air-conditioning outer shell has a main compartment 1 and an auxiliary compartment 2 which are connected to each other. An installation position (not shown) for installing an electric control box is defined between the main compartment 1 and the auxiliary compartment 2, which is convenient for the separate arrangement of different functional modules of the electric control box. The electric control box consists of a heat dissipation waterproof box 3 and an assembly box 4, which are respectively arranged in the main compartment 1 and the auxiliary compartment 2 of the outer shell. At the connection between the heat dissipation waterproof box 3 and the assembly box 4, a plurality of heat dissipation grilles 5 are arranged at intervals to promote air circulation and enhance the heat dissipation effect. The heat dissipation waterproof box 3 is internally designed with a connecting structure of a vent 6 and a ventilation cavity 7, wherein the vent 6 is arranged downward to facilitate the discharge of hot air through the heat dissipation channel formed by the ventilation cavity 7 and the vent 6, and then the hot air is drawn out of the outer shell by the negative pressure formed by the rotation of the fan in the main compartment 1 (this is the prior art and is not subject to too many restrictions), which greatly improves the heat dissipation efficiency.

[0029] The heat dissipation waterproof box 3 comprises:

[0030] A heat sink 301 is connected to the assembly box 4, and the heat sink grill 5 is formed on the heat sink 301;

[0031] The waterproof cover plate 302 is covered on the heat dissipation grille 5 of the heat dissipation plate 301 , and the vent 6 and the ventilation cavity 7 are formed between the waterproof cover plate 302 and the heat dissipation plate 301 , and the periphery of the waterproof cover plate 302 is fixedly connected to the heat dissipation plate 301 to partially close the heat dissipation grille 5 .

[0032] In this embodiment, the heat sink 301 is connected to the assembly box 4, and the heat sink grille 5 is directly formed on the heat sink 301, which increases the heat dissipation area and promotes air circulation, so that the heat can be dissipated to the external environment through the grille more quickly. In order to achieve good waterproof performance while ensuring heat dissipation efficiency, a waterproof cover plate 302 is arranged above the heat sink grille 5 of the heat sink 301. The waterproof cover plate 302 is tightly covered in the heat sink grille 5 area of ​​the heat sink 301, ensuring that the heat dissipation channel of the vent 6 and the ventilation cavity 7 can be formed between the heat sink 301 and the heat sink 301, and can effectively block the intrusion of external moisture; the vent 6 and the ventilation cavity 7 formed by the waterproof cover plate 302 and the heat sink 301 provide a heat dissipation channel for the discharge of hot air, and the negative pressure formed by the fan is used in the outer compartment to draw the hot air out through the heat dissipation channel, and the waterproof cover plate 302 The vent 6 formed by the water cover 302 is open at the bottom and closed at the top, so that the hot air flow can only be discharged from the heat dissipation channel, which promotes the smooth discharge of the hot air flow. The ventilation cavity 7 serves as a transition space for the hot air flow, further accelerating the heat discharge process. The periphery of the waterproof cover 302 is combined with the heat dissipation plate 301 by a firm fixed connection method (such as welding, screw fixing or snap-on design), ensuring the close combination of the two, which not only stabilizes the overall structure, but also realizes the partial closure of the heat dissipation grille 5, effectively balancing the needs of heat dissipation and waterproofing, and improving the working stability and reliability of the electrical control box in harsh environments. The heat dissipation waterproof box 3 protrudes from the outside of the auxiliary warehouse 2 and is located in the outer warehouse. The warehouse wall of the heat dissipation waterproof box 3 that is expanded laterally is used to block rainwater flowing from top to bottom, thereby achieving a waterproof effect.

[0033] A notch 303 is provided at the corresponding position of the heat dissipation plate 301 and the waterproof cover plate 302 , and the notch 303 is recessed upward.

[0034] In this embodiment, a gap 303 is provided at the corresponding position of the heat dissipation waterproof box 3 and the waterproof cover plate 302. The gap 303 is used to avoid the air guide ring of the front side plate of the air conditioner outdoor unit, and plays a avoiding role. The size of the gap 303 can be adjusted according to the size specification of the air guide ring.

[0035] The heat sink 301 and the electric control box are arranged perpendicular to each other.

[0036] In this embodiment, the heat sink 301 and the main structure of the electric control box are designed to be placed vertically to each other. The advantage of this layout is that it can make full use of the space, especially when the internal space of the electric control box is limited, the vertically arranged heat sink 301 can maximize the heat dissipation area, does not occupy too much horizontal or vertical space, and improves the space utilization efficiency. At the same time, the vertically arranged heat sink 301 can also enhance the stability and mechanical strength of the entire electric control box structure. Through the horizontal and vertical support structure design, the heat sink 301 can provide additional rigid support for the electric control box, especially when it is subjected to external impact or vibration, which helps to protect the internal electronic components from damage.

[0037] The auxiliary compartment 2 is provided with a fixing plate 8 , and the assembly box 4 is detachably fixed to the fixing plate 8 .

[0038] In this embodiment, a fixing plate 8 is provided in the auxiliary compartment 2, and the fixing plate 8 is used to support and fix the assembly box 4, aiming to provide a stable installation platform for the assembly box 4, and ensure the stability and safety of the electric control box during operation.

[0039] The fixing plate 8 is provided with a plurality of bayonet holes 801 , and the assembly box 4 is provided with a plurality of claws 401 corresponding to the plurality of bayonet holes one by one, and each claw 401 is detachably connected to each bayonet hole 801 .

[0040] In this embodiment, the fixing plate 8 is preset with a plurality of bayonet holes 801, and the corresponding parts of the assembly box 4 are provided with a plurality of claws 401 having the same number as the bayonet holes 801 and corresponding positions one by one, and each pair of bayonet holes 801 and claws 401 form a stable connection point, ensuring that the assembly box 4 is stable and immovable after installation, and each claw 401 is designed as a detachable connection structure, so that the claw 401 can be easily inserted into or withdrawn from the bayonet hole 801 on the fixing plate 8, and the installation or removal of the assembly box 4 can be completed without complicated tools or a lot of force, thereby improving the installation efficiency. The connection mode between the bayonet holes 801 and the claws 401 not only ensures the high stability of the assembly box 4 in the working state, and prevents loosening caused by vibration or external force, but also retains the necessary flexibility, making maintenance or replacement simple and quick.

[0041] The fixing plate 8 and the assembly box 4 are respectively provided with a matching clamping plate 802 and a clamping block 402 . The clamping block 402 is detachably provided on the clamping plate 802 for fixing or releasing the assembly box 4 .

[0042] In this embodiment, in order to further fix the assembly box 4, the fixing plate 8 and the assembly box 4 are respectively provided with matching clamping plates 802 and clamping blocks 402, forming additional fixing points and enhancing the stability of the assembly box 4 when being fixed.

[0043] One of the clamping claw 401 and the clamping block 402 is located on a side surface of the assembly box 4 .

[0044] In this embodiment, the fixing point formed by the claw 401 and the socket 801 is located at the top of the assembly box 4, and the fixing point formed by the block 402 and the clamping plate 802 is located on the side of the assembly box 4, so that the assembly box 4 is limited in multiple directions, which can effectively prevent the assembly box 4 from loosening or falling off, thereby ensuring the long-term stable operation of the electronic control system.

[0045] The fixing plate 8 is provided with a cooling plate 9 , and the assembly box 4 is provided with a groove 403 for avoiding the cooling plate 9 .

[0046] In this embodiment, the groove 403 is used to install the cooling plate 9. The front side of the cooling plate 9 is used to fit multiple power devices that are prone to heat on the electronic control component. A refrigerant tube (not shown) is arranged between the back side of the cooling plate 9 and the fixed plate 8. The refrigerant tube has a continuously flowing liquid refrigerant. The refrigerant absorbs heat after evaporation and is used to transfer heat to the power devices to achieve heat dissipation.
