Description

Technical Field

[0001] This application belongs to the field of air conditioning technology, and in particular relates to an electrical control box assembly and an outdoor unit of an air conditioner. Background Technology

[0002] An outdoor unit of an air conditioner typically has a fan chamber and a compressor chamber separated by a partition, with the electrical control box mounted on the partition. To dissipate heat from the electrical components inside the control box, a heat dissipation channel is provided inside the control box connecting the fan chamber and the compressor chamber. By allowing airflow from the compressor chamber to flow through the heat dissipation channel to the fan chamber, the airflow carries away the heat from the various components inside the control box, thus cooling the electrical components inside the control box.

[0003] However, the heat dissipation efficiency of the existing control box is low, and the heat inside the control box cannot be dissipated quickly, which may cause the temperature of the control components to be too high and the air conditioner to malfunction. Utility Model Content

[0004] This application provides an electrical control box assembly, an outdoor air conditioning unit, and an air conditioner to solve the problem of low heat dissipation efficiency in existing electrical control boxes.

[0005] In a first aspect, embodiments of this application provide an electrical control box assembly, the electrical control box assembly including an electrical control box, a heat sink, and a baffle plate, the electrical control box having a circuit board inside, the heat sink passing through the electrical control box and abutting against the circuit board; the baffle plate being disposed on the outside of the electrical control box, the baffle plate and the outer surface of the electrical control box forming a heat dissipation channel, the heat dissipation channel having an air inlet and an air outlet, the air inlet being opened on the electrical control box, and the air outlet facing the heat sink.

[0006] Optionally, the electrical control box is provided with multiple heat dissipation holes, which form the air inlet of the heat dissipation channel.

[0007] Optionally, the plurality of heat dissipation holes are evenly arranged, and / or the heat dissipation holes are strip-shaped holes.

[0008] Optionally, the electrical control box includes a first sidewall, the heat sink passes through the first sidewall, and the air inlet is located at the upper end of the first sidewall or on the side of the first sidewall.

[0009] Optionally, the radiator includes a plurality of heat sinks, the air outlet extends along the length or height of the first sidewall, and the plurality of heat sinks are arranged sequentially at intervals along the extension direction of the air outlet.

[0010] Optionally, the top surface of the baffle is inclined downwards.

[0011] Optionally, the top surface of the baffle plate has an inclination angle of 30° to 45°.

[0012] Optionally, the upper edge of the baffle is higher than the upper edge of the air inlet.

[0013] Secondly, this application also provides an outdoor air conditioner unit, which includes a casing, a partition, a fan, and the aforementioned electrical control box assembly. A chamber is formed inside the casing, and the partition divides the chamber into a fan chamber and a compressor chamber. The fan is disposed in the fan chamber. The electrical control box assembly is disposed on the partition, and the air inlet of the heat dissipation channel of the electrical control box assembly is connected to the compressor chamber, and the air outlet of the heat dissipation channel is connected to the fan chamber.

[0014] Thirdly, embodiments of this application also provide an air conditioner, which includes the aforementioned outdoor unit.

[0015] The electrical control box assembly, outdoor air conditioner unit, and air conditioner provided in this application embodiment have a heat sink of the electrical control box assembly that passes through the electrical control box and abuts against the circuit board. A baffle plate is set on the outside of the electrical control box and forms a heat dissipation channel with the outer surface of the electrical control box. The air inlet of the heat dissipation channel is opened on the electrical control box, and the air outlet faces the heat sink. When the electrical control box assembly is applied to the outdoor air conditioner unit, the air inlet and air outlet of the heat dissipation channel are connected to the compressor chamber and fan chamber of the outdoor air conditioner unit, respectively. This allows the airflow in the compressor chamber to flow through the heat dissipation channel to the fan chamber and blown towards the heat sink from the air outlet, thereby removing the heat from the heat sink and the inside of the electrical control box and achieving efficient heat dissipation.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features.

[0024] In this application, the term "exemplary" is used to mean "serving as an example, illustration, or illustration." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0025] This application provides an electrical control box assembly, such as... Figure 1 and Figure 2As shown, the electrical control box assembly includes an electrical control box 100, a radiator 200, and a baffle plate 300. The electrical control box 100 has a circuit board 110 inside, and several components are installed on the circuit board 110. The radiator 200 passes through the electrical control box 100 and abuts against the circuit board 110 (i.e., the radiator 200 is in contact with the circuit board 110). The baffle plate 300 is disposed on the outside of the electrical control box 100. The baffle plate 300 and the outer surface of the electrical control box 100 form a heat dissipation channel. The heat dissipation channel has an air inlet 401 and an air outlet 402. The air inlet 401 is opened on the electrical control box 100, and the air outlet 402 faces the radiator 200.

[0026] The electrical control box assembly provided in this application embodiment has a heat sink 200 inserted through the electrical control box 100 and abutting against the circuit board 110. A baffle plate 300 is disposed on the outside of the electrical control box 100 and forms a heat dissipation channel with the outer surface of the electrical control box 100. The air inlet 401 of the heat dissipation channel is opened on the electrical control box 100, and the air outlet 402 faces the heat sink 200. When the electrical control box assembly is applied to the outdoor unit of the air conditioner, the air inlet 401 and the air outlet 402 of the heat dissipation channel are respectively connected to the compressor chamber 502 and the fan chamber 501 of the outdoor unit of the air conditioner. This allows the airflow in the compressor chamber 502 to flow through the heat dissipation channel to the fan chamber 501 and blown from the air outlet 402 to the heat sink 200, thereby removing the heat from the heat sink 200 and the interior of the electrical control box 100, achieving efficient heat dissipation and solving the problem of low heat dissipation efficiency in the prior art.

[0027] At the same time, the baffle plate 300 can effectively prevent water from entering the electrical control box 100 from the air inlet 401 of the heat dissipation channel, solving the problem of poor waterproof performance in the prior art. This makes it less likely for water droplets caused by the rotation of the fan 700 of the outdoor unit to splash into the electrical control box 100 when the outdoor unit is running, thereby reducing the risk of short circuit caused by water ingress.

[0028] In some embodiments of this application, the electrical control box 100 has multiple heat dissipation holes 101, which form the air inlet 401 of the heat dissipation channel. It is understood that the number of heat dissipation holes 101 can be set according to actual needs, as long as the total opening area of ​​the multiple heat dissipation holes 101 can meet the heat dissipation airflow requirements. For example, as... Figure 1 As shown, the electrical control box 100 has six heat dissipation holes 101, which form the air inlet 401 of the heat dissipation channel.

[0029] Optionally, multiple heat dissipation holes 101 are evenly arranged. By evenly arranging multiple heat dissipation holes 101 on the electrical control box 100, air can be evenly blown from the air outlet 402 of the heat dissipation channel to the radiator 200, thereby improving the heat dissipation effect.

[0030] Optionally, the heat dissipation hole 101 can be a strip-shaped hole. By setting the heat dissipation hole 101 as a strip-shaped hole, the air resistance when the airflow enters the heat dissipation channel can be reduced, thereby improving the heat dissipation effect.

[0031] In some embodiments of this application, the electrical control box 100 includes a first sidewall 102, a heat sink 200 passing through the first sidewall 102, and an air inlet 401 opened at the upper end of the first sidewall 102 or the side of the first sidewall 102.

[0032] like Figure 2 As shown, in some embodiments, the air inlet 401 of the heat dissipation channel is located at the upper end of the first side wall 102. By placing the air inlet 401 at the upper end of the first side wall 102, the possibility of water droplets splashed up by the fan 700 of the outdoor unit of the air conditioner entering the electrical control box 100 through the air inlet 401 can be reduced, thereby protecting the electronic components on the circuit board 110 from damage by water droplets.

[0033] Of course, in other embodiments, the air inlet 401 of the heat dissipation channel can also be located on the side of the first sidewall 102, for example in... Figure 2 In the orientation shown, the air inlet 401 of the heat dissipation channel is opened on the left or right side of the first side wall 102, which can be set according to actual needs.

[0034] Optionally, the radiator 200 includes multiple heat sinks, and the air outlet 402 extends along the length or height of the first sidewall 102. The multiple heat sinks are arranged sequentially at intervals along the extension direction of the air outlet 402. This arrangement allows air to smoothly enter and disperse in the gaps between adjacent heat sinks when it blows from the air outlet 402 of the heat dissipation channel to the radiator 200, thereby ensuring full contact between the air and the radiator 200 and guaranteeing good heat exchange efficiency.

[0035] For example, such as Figure 1 As shown, the air outlet 402 is positioned downwards and extends along the length of the first sidewall 102. The radiator 200 is located below the air outlet 402, and multiple heat dissipation fins of the radiator 200 are arranged at intervals along the extension direction of the air outlet 402 (i.e., the length direction of the first sidewall 102). Alternatively, the air outlet 402 is positioned to the left and extends along the height direction of the first sidewall 102. The radiator 200 is located to the left of the air outlet 402, and multiple heat dissipation fins of the radiator 200 are arranged at intervals along the extension direction of the air outlet 402 (i.e., the height direction of the first sidewall 102). Or, the air outlet 402 is positioned to the right and extends along the height direction of the first sidewall 102. The radiator 200 is located to the right of the air outlet 402, and multiple heat dissipation fins of the radiator 200 are arranged at intervals along the extension direction of the air outlet 402 (i.e., the height direction of the first sidewall 102).

[0036] Optionally, the electrical control box 100 also includes a second sidewall 103, which is connected to the first sidewall 102 and the two are arranged at an angle. Specifically, when the electrical control box assembly is applied to an outdoor unit of an air conditioner, the first sidewall 102 is installed on the partition 600 of the outdoor unit of the air conditioner, and the second sidewall 103 is installed on the housing 500 of the outdoor unit of the air conditioner.

[0037] In some embodiments of this application, the top surface of the baffle 300 is inclined downwards. By inclining the top surface of the baffle 300 downwards, water splashed onto the top of the baffle 300 can flow down naturally without accumulating.

[0038] Optionally, the tilt angle of the top surface of the baffle 300 is 30° to 45°, that is, the angle between the top surface of the baffle 300 and the height direction of the electrical control box 100 is 30° to 45°. For example, the tilt angle of the top surface of the baffle 300 can be 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, 45°, or any range between two values, and can be set according to actual needs.

[0039] Optionally, the upper edge of the baffle 300 is higher than the upper edge of the air inlet 401. By setting the upper edge of the baffle 300 to be higher than the upper edge of the air inlet 401, it can be ensured that water cannot enter the electrical control box 100 from the air inlet 401.

[0040] Optionally, the baffle 300 can be made of corrosion-resistant metal and fixed to the outer wall of the electrical control box 100 by bolts or clips. Optionally, the baffle 300 covers more than 80% of the area of ​​the air inlet 401, that is, along the axial direction of the air inlet 401, the projection of the baffle 300 on the electrical control box 100 covers more than 80% of the area of ​​the air inlet 401.

[0041] This application also provides an outdoor unit for an air conditioner, such as... Figure 3 As shown, the outdoor unit of the air conditioner includes a casing 500, a partition 600, a fan 700, and an electrical control box assembly. The specific structure of the electrical control box assembly is as described in the above embodiment. The casing 500 contains a chamber, which is divided into a fan chamber 501 and a compressor chamber 502 by the partition 600. The fan 700 is disposed within the fan chamber 501. The electrical control box assembly is mounted on the partition 600. The air inlet 401 of the heat dissipation channel of the electrical control box assembly is connected to the compressor chamber 502, and the air outlet 402 of the heat dissipation channel is connected to the fan chamber 501.

[0042] Specifically, when the outdoor unit of the air conditioner is running, the fan 700 in the fan cavity 501 rotates, causing the fan cavity 501 to form a negative pressure, which in turn drives the airflow in the compressor cavity 502 to enter the heat dissipation channel from the air inlet 401, and then blows it from the air outlet 402 to the radiator 200, and finally flows into the fan cavity 501. During the airflow process, it will carry away the heat inside the radiator 200 and the electrical control box 100, achieving efficient heat dissipation and quickly cooling the circuit board 110 inside the electrical control box 100.

[0043] It is understood that since this air conditioner outdoor unit adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0044] Optionally, the outdoor unit of the air conditioner may also include other components, such as a motor bracket installed in the fan chamber 501 and a compressor 800 installed in the compressor chamber 502.

[0045] This application also provides an air conditioner, which includes an outdoor unit. The specific structure of the outdoor unit is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.
