Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning equipment, and in particular to an air conditioner. Background Art

[0002] When a variable-frequency air conditioner is operating, the temperature rise of the components in the electrical enclosure must be kept to a minimum, otherwise it will affect their proper operation and service life. This is especially true for the electrolytic capacitors in the enclosure, which have even higher requirements due to their service life. High ambient temperatures place higher demands on the air conditioner's cooling comfort, meaning sufficient cooling output even under high-temperature conditions. This requires that the frequency of the variable-frequency air conditioner remain constant in these conditions. However, higher frequencies lead to even higher component temperature rises. Therefore, addressing excessive component temperature rise in high-temperature environments is a major challenge for integrated variable-frequency air conditioners.

[0003] Existing inverter air conditioners use a radiator to dissipate heat from the electrical box to reduce the temperature rise of the controller components. In integrated inverter air conditioners, the electrical box radiator is often placed in the outdoor air duct, dissipating heat through air cooling. Specifically, the inverter electrical box is fixed to the front baffle, and the inverter electrical box and radiator are placed in the outdoor air inlet duct, using air cooling to dissipate heat from the outdoor air. However, to meet rain test requirements and prevent the electrical box from being exposed to outdoor rain, which would pose a safety hazard, the electrical box and radiator are typically located away from the outdoor air inlet grille, resulting in poor heat dissipation. Furthermore, because the electrical box is completely encased in sheet metal, creating a relatively sealed interior, heat generated by the components accumulates inside the box and cannot dissipate, placing the components in a relatively closed, high-temperature environment, further increasing their temperature. In harsh outdoor environments, the outdoor ambient temperature is high, and the overall load is also greater. The high air temperature surrounding the radiator prevents effective heat dissipation, resulting in excessive component temperature rise and the system becoming inoperable. Summary of the Invention

[0004] The main purpose of the present invention is to provide an air conditioner to solve the problem in the prior art that when the outdoor operating environment temperature is high, the temperature rise of components is high, the components are easily damaged or the service life is affected, and the components cannot operate normally.

[0031] The air conditioner of the present invention includes a housing 10, a partition 20 and an electrical box 30. The electrical box 30 is placed horizontally in the housing 10. The first accommodating cavity of the box body 31 is provided with controller components. The box body 31 is provided with a radiator 40. The radiator 40 is located in the second air duct on the outdoor side 12. The electrical box 30 is normally cooled by the outdoor air cooling cycle. In addition, the air conditioner is provided with a first opening 311 on the electrical box 30, so that the first accommodating cavity is connected to the indoor side 11 through the first opening 311, so that the gas on the indoor side 11 can radiate the controller in the electrical box 30. The components are cooled; when the outdoor ambient temperature is high, the ambient temperature of the indoor side 11 will be much lower than that of the outdoor side 12, and the low-temperature air on the indoor side 11 can flow into the first accommodating cavity of the box body 31 through the first opening 311, thereby efficiently cooling the controller components, reducing the temperature rise of the controller components, protecting the controller components from damage, and ensuring the normal and stable operation of the air conditioner, thereby solving the problem in the prior art that when the outdoor operating ambient temperature is high, the temperature rise of the components is high, the components are easily damaged or the service life is affected, and the air conditioner cannot operate normally.

[0032] Optionally, the air conditioner of the present invention is an integrated variable frequency air conditioner, and the electrical appliance box 30 is a variable frequency electrical appliance box.

[0035] In this embodiment, the air conditioner also includes a seal, which is arranged in the notch 21 and clamped between the electrical box 30 and the partition 20. This arrangement allows the seal to seal the connection between the electrical box 30 and the partition 20, preventing the low-temperature air in the room from flowing out from between the electrical box 30 and the partition 20, avoiding the loss of part of the cooling capacity and affecting the cooling effect; it can also prevent the electrical box 30 from not being able to flow into a sufficient amount of low-temperature air, affecting the heat dissipation of the controller components.

[0036] Optionally, the sealing member is a sponge, flannel or sealing putty.

[0037] In this embodiment, the electrical box 30 also includes a mainboard, which is arranged in the box body 31. A mounting hole is provided at the bottom of the second box body 313. The radiator 40 is passed through the mounting hole so that the radiator 40 is connected to the mainboard through the mounting hole. This arrangement allows the outdoor cold air to pass through the radiator 40 to dissipate heat to the components on the mainboard.

[0038] In this embodiment, the radiator 40 located outside the electrical box 30 is located below the second box body 313. This arrangement can prevent rainwater from gathering on the radiator 40 and flowing into the second box body 313 through the gap, causing safety hazards.

[0041] In this embodiment, the first opening 311 is communicated with the indoor air inlet 111 of the indoor side 11 .

[0042] During specific implementation, the low-temperature air on the indoor side 11 flows into the box body 31 through the indoor air inlet 111 and the first opening 311 in sequence, and efficiently dissipates heat for the controller components.

[0043] In this embodiment, the air conditioner also includes: a wire box 50 for accommodating cables, the wire box 50 has a wire hole 51, a second opening 52 and a second accommodating cavity 53, the wire hole 51 and the second opening 52 are both connected to the second accommodating cavity 53, the wire hole 51 is connected to the indoor air inlet 111, and the second opening 52 is connected to the first opening 311.

[0044] During specific implementation, the low-temperature air on the indoor side 11 flows into the wire hole 51 through the indoor air inlet 111, flows through the second accommodating cavity 53 and the second opening 52 in sequence from the wire hole 51, and then flows into the first opening 311, and flows into the box body 31 from the first opening 311, so as to efficiently dissipate heat for the controller components.

[0045] In this embodiment, a first air duct 60 is provided on the indoor side 11; the wire box 50 and the electrical box 30 are both provided below the first air duct 60.

[0046] Specifically, the wire box 50 includes a main body and a surrounding plate 70 , which enclose a second accommodating cavity 53 . The wire hole 51 is provided on the main body, and the surrounding plate 70 is fixedly connected to the housing 10 .

[0047] In this embodiment, the indoor side 11 is provided with a plurality of indoor air inlets 111, and the plurality of indoor air inlets 111 are all connected to the first opening 311. The plurality of indoor air inlets 111 includes an embodiment of two indoor air inlets 111.

[0048] Optionally, there are two indoor air inlets 111, one at the bottom and one at the side of the shell 10, and each indoor air inlet 111 is provided with an air inlet grille 90; so that the indoor low-temperature air can pass through the air inlet grille 90 and the wire hole 51 into the interior of the electrical box 30, so that the interior of the electrical box 30 maintains a relatively low temperature air environment.

The first box body 312 is positioned on the indoor side 11 and is connected to the indoor air inlet 111 of the indoor side 11 through the first opening 311. The low-temperature air on the indoor side 11 can exchange heat with the first box body 312, dissipating heat from the first box body 312. In a high temperature environment, the ambient temperature of the indoor side 11 is much lower than the ambient temperature of the outdoor side 12. The electrical box 30 is in a lower ambient temperature. The low-temperature air will efficiently dissipate heat for the components of the electrical box 30, reduce the temperature rise of the controller components, protect the controller components from damage, and ensure the normal and stable operation of the whole machine; when the outdoor ambient temperature is high, the cooling operation is carried out, the load of the whole machine increases, the air temperature around the radiator 40 is high, and the pure air cooling effect is poor, and it cannot effectively reduce the temperature of the components. The electrical box 30 is provided with a first opening 311, which is connected to the indoor side wire box 50 and communicates with the low-temperature air on the indoor side 11 through the wire hole 51.

The electrical box 30 is located below the first air duct and is placed horizontally. The first box body 312 is located on the indoor side 11 and the second box body 313 is located in the second air duct.

The seal is provided in the notch 21 and is clamped between the electrical box 30 and the partition 20. The seal can be a sponge, flannel or sealing putty; after the electrical box 30 is installed, the wire box 50 is inserted from the front to the back and fixed to the whole machine by screws; an air inlet grille 90 is provided at the indoor air inlet 111; indoor air inlets 111 are provided at the bottom and sides of the shell 10, so that the indoor low-temperature air can pass through the air inlet grille 90 and the wire hole 51 into the interior of the electrical box 30, so that the interior of the electrical box 30 maintains a relatively low temperature air environment.
