Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for electrical control boxes, specifically to an electrical control box and an outdoor unit for an air conditioner. Background Technology

[0002] Traditional air conditioner outdoor units typically have their electrical control box located inside the compressor chamber. However, the compressor chamber and fan chamber are separated by a baffle plate, preventing the cooling airflow from the fan chamber from directly passing through the electrical control box area. The electronic components inside the control box generate a significant amount of heat during operation; if the cooling path doesn't pass through the control box, heat can easily accumulate, reducing component lifespan. Furthermore, the airflow duct formed by the air inlet on the outdoor unit's side panel and the air outlet on the baffle plate does not cover the control box area, resulting in low cooling efficiency and inadequate protection against external water. Utility Model Content

[0003] Therefore, this utility model embodiment provides an electrical control box and an air conditioner outdoor unit, which makes heat dissipation of the electrical control box more efficient and waterproof performance better.

[0004] To solve the above problems, this utility model provides an electrical control box, which is installed in the outdoor unit of an air conditioner. The outdoor unit has a windproof vertical plate and a side plate. The windproof vertical plate divides the interior of the outdoor unit into a fan chamber and a compressor chamber. The electrical control box is installed in the compressor chamber, and the side plate is installed on the other side of the compressor chamber opposite to the windproof vertical plate. The windproof vertical plate has an air outlet, and the side plate has an air inlet. An air duct is formed between the air inlet, the compressor chamber, the air outlet, and the fan chamber. The electrical control box is installed along the path of the air duct. A first water-blocking component is installed near the air outlet, and a second water-blocking component is installed near the air inlet.

[0005] Compared with existing technologies, the technical effects achieved by this solution are as follows: By placing the control box on the air duct path formed by the air inlet, compressor cavity, air outlet, and fan cavity in series, the cooling airflow is forced to flow across the surface of the control box, directly carrying away the heat from the electronic components and significantly improving heat dissipation efficiency. Simultaneously, the airflow dynamically isolates the external high-temperature environment, preventing heat accumulation in the compressor cavity, ensuring stable operation of the control box under high-temperature conditions, and extending component lifespan. The first water-blocking component intercepts condensate splashing in from the air outlet, preventing water from flowing back into the control box along the air duct; the second water-blocking component blocks rainwater intruding from the air inlet, forming a two-way waterproof barrier. While maintaining unobstructed airflow for cooling, it prevents liquid water from contacting the internal components of the control box, balancing efficient heat dissipation with comprehensive waterproofing, and reducing the risk of short circuits in humid and hot environments.

[0006] In one embodiment of this utility model, the first water-blocking component further includes: a housing, the housing being connected to the wind-blocking upright plate, and the housing surrounding the air outlet to form an accommodating space; the housing also has a first opening, the first opening communicating with the compressor cavity.

[0007] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the housing surrounds the air outlet to form a containment space, which concentrates and confines the splashed water to a local area, preventing water droplets from spreading to the compressor cavity; the first opening connects to the compressor cavity to maintain the continuity of airflow in the air duct, ensuring that the heat dissipation airflow flows through the electrical control box without obstruction, while the containment space physically isolates the air outlet from the electrical control box, blocking the direct splashing path of water, and realizing the partitioned management of heat dissipation and waterproof space.

[0008] In one embodiment of this utility model, a second opening is provided at the bottom of the containing space; the second opening is connected to the ventilation fan chamber; wherein, the second opening is used to drain water from the containing space.

[0009] Compared with existing technologies, the technical effects achieved by this solution are as follows: the second opening at the bottom of the containment space directs the collected water to the fan cavity, and the fan cavity drainage system quickly drains the accumulated water, preventing water from overflowing or seeping into the compressor cavity; the flow guidance process does not interfere with the main airflow path of the duct, maintains the heat dissipation efficiency of the electrical control box area, and eliminates the risk of moisture and corrosion caused by water retention.

[0010] In one embodiment of this utility model, the air outlet and the first opening are misaligned.

[0011] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the misaligned design of the air outlet and the first opening forms a non-linear airflow channel, which forces the airflow to generate turbulence in the containment space to improve the uniformity of heat dissipation; at the same time, the misaligned structure prevents water from splashing straight through the first opening of the air outlet, allowing the airflow to only pass through in a detour, and uses the principle of inertial separation to make the water droplets fall after colliding with the shell wall, which greatly reduces the probability of water droplets entering the compressor cavity.

[0012] In one embodiment of this utility model, the second water-blocking component further includes: a first blocking member, which is disposed near the air inlet; and a second blocking member, which is disposed near the side of the electrical control box.

[0013] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the first blocking component directly intercepts large-diameter water droplets carried by the high-speed airflow in the air inlet, and the second blocking component further blocks the atomized water vapor that bypasses the first blocking component. The dual-stage water-blocking structure decomposes the impact energy of the water flow. The two components work together to form a gradually narrowing guide channel, guiding the airflow to adhere to the surface of the electrical control box to enhance heat dissipation, while guiding the water droplets to the bottom of the side plate for discharge, thus avoiding the formation of a water film on the surface of the electrical control box that would affect heat dissipation.

[0014] In one embodiment of this utility model, the air inlet is provided with multiple air inlets, and the first blocking member further includes: the first blocking member is provided with multiple ventilation openings; and the multiple ventilation openings are staggered with the multiple air inlets.

[0015] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the misalignment of the vent and the air inlet forms a labyrinthine airflow path, which prolongs the collision path of water droplets within the water-blocking component, and the water droplets fall by consuming kinetic energy through multiple collisions.

[0016] In one embodiment of this utility model, the first blocking member is inclined relative to the second blocking member; the second blocking member is perpendicular to the bottom surface of the electrical control box.

[0017] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the first blocking component is tilted to guide the airflow upward around the top of the electronic control box, avoiding direct blowing on the sensitive areas of electronic components; the tilted surface causes the collision water droplets to slide down the inclined surface to the edge of the side plate for discharge; the second blocking component is vertically set to form an end water-blocking wall, intercepting the rebound water droplets and guiding the airflow to flow evenly along the bottom of the electronic control box, enhancing the heat dissipation effect of the high-heat components at the bottom, and establishing gravity drainage guidance.

[0018] In one embodiment of this utility model, the first blocking member and the second blocking member are arranged in a V-shape.

[0019] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: by setting the first and second blocking components in a V-shape, external rainwater can be better blocked when it enters the interior through the air inlet. The V-shape design allows the rainwater to be blocked on the second blocking component, and the larger contact area of ​​the inclined surface can better receive rainwater, thus improving the overall waterproof performance.

[0020] In one embodiment of this utility model, the air outlet is provided with multiple air outlets; each air inlet and each air outlet is provided with a shielding component, which shields but does not seal each air inlet and each air outlet.

[0021] Compared with existing technologies, the technical effect achieved by this solution is that by setting up shielding components to block direct water splashing in, but without blocking air intake and exhaust, the overall protection is stronger and the waterproof effect is better.

[0022] This utility model also provides an air conditioner outdoor unit, which includes: an outdoor unit body; and an electrical control box as described above is provided inside the outdoor unit body.

[0023] The air conditioner outdoor unit in this embodiment includes an outdoor unit body, and the electrical control box is located in the outdoor unit body. Therefore, it has all the beneficial effects of the electrical control box in any embodiment of this utility model, which will not be repeated here.

[0024] By adopting the technical solution of this utility model, the following technical effects can be achieved: (1) By placing the electrical control box on the air duct path formed by the air inlet, compressor cavity, air outlet and fan cavity in series, the heat dissipation airflow is forced to flow through the surface of the electrical control box, directly carrying away the heat of the electronic components, which significantly improves the heat dissipation efficiency; at the same time, the air duct airflow is used to dynamically isolate the external high temperature environment, avoid the local accumulation of heat in the compressor cavity, ensure the stable operation of the electrical control box under high temperature conditions, and extend the service life of the components. (2) The first water-blocking component intercepts the condensate splashed in from the air outlet, preventing water from flowing back into the electrical control box along the air duct; the second water-blocking component blocks the rainwater that enters from the air inlet, forming a two-way waterproof barrier. While maintaining the smooth airflow of the air duct for heat dissipation, it isolates liquid water from contacting the internal components of the electrical control box, taking into account both efficient heat dissipation and comprehensive waterproofing requirements, and reducing the risk of short circuit in a humid and hot environment. (3) The staggered design of the air outlet and the first opening forms a non-linear airflow channel, which forces the airflow to generate turbulence in the containment space to improve the heat dissipation uniformity; at the same time, the staggered structure blocks the water from the air outlet from splashing straight through the first opening, allowing the airflow to pass through in a detour. The principle of inertial separation is used to make the water droplets fall after colliding with the shell wall, which greatly reduces the probability of water droplets entering the compressor cavity; the first blocking component directly intercepts the large-diameter water droplets carried by the high-speed airflow of the air inlet, and the second blocking component blocks the atomized water vapor that bypasses the first blocking component. The dual-stage water-blocking structure decomposes the impact energy of the water flow; the two work together to form a gradually narrowing guide channel, which guides the airflow to adhere to the surface of the electrical control box to enhance heat dissipation, while guiding the water droplets to the bottom of the side plate for discharge, avoiding the formation of a water film on the surface of the electrical control box that affects heat dissipation.

[0027] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] [First Embodiment] See Figures 1-5 This utility model provides an electrical control box 100, which is disposed in an outdoor unit 200 of an air conditioner. The outdoor unit 200 is provided with a windproof upright plate 210 and a side plate 220. The windproof upright plate 210 divides the interior of the outdoor unit 200 into a fan chamber 230 and a compressor chamber 240. The electrical control box 100 is disposed in the compressor chamber 240, and the side plate 220 is disposed on the other side of the compressor chamber 240 opposite to the windproof upright plate 210. The windproof upright plate 210 is provided with an air outlet 250, and the side plate 220 is provided with an air inlet 260. An air duct is formed between the air inlet 260, the compressor chamber 240, the air outlet 250, and the fan chamber 230. The electrical control box 100 is disposed on the path of the air duct. A first water-blocking component 110 is disposed near the air outlet 250. A second water-blocking component 120 is disposed near the air inlet 260.

[0029] Specifically, the electrical control box 100 is placed horizontally inside the compressor cavity 240, and an air outlet 250 is opened on the side of the air-insulating plate 210 near the electrical control box 100. Specifically, the air outlet 250 has multiple air outlets 251, and the air outlets 251 are connected to the ventilation fan cavity 230. On the side of the multiple air outlets 251 near the electrical control box 100, the electrical control box 100 is integrally provided with a first water-blocking component 110, that is, the multiple air outlets 251 are surrounded by the housing 111, thereby preventing water from the fan cavity 230 from directly contacting the components on the electrical control box 100 from the air outlets 251. At the same time, a first opening 112 is provided to facilitate airflow interaction.

[0030] Furthermore, on the other side of the electrical control box 100, a first blocking member 121 and a second blocking member 122 are provided. Multiple vents 123 are provided on the first blocking member 121 to allow airflow interaction with multiple air inlets 261. The staggered arrangement of the vents 123 and air inlets 261 prevents external rainwater from directly contacting the electrical control box 100. The second blocking member 122 is also provided for secondary protection, thereby enhancing the waterproof function.

[0031] Specifically, the first water-blocking component 110, which is set on the side near the fan cavity 230, can be a water-blocking cover. The water-blocking cover is specifically set on the base shell of the electrical control box 100 and completely covers the air outlet 251 on the windproof plate 210. This ensures that even if water droplets in the fan cavity 230 pass through the air outlet 251, they will be completely received by the water-blocking cover and hit the water-blocking cover. This prevents the water droplets from falling directly onto the electrical control box 100 and affecting the normal operation of the electronic components on the electrical control box 100, thus better ensuring the safety of the electronic components on the electrical control box 100.

[0032] Furthermore, a receiving groove can be provided inside the water baffle, and the receiving groove is integrally formed with the water baffle. The receiving groove is specifically located below the water baffle that receives water droplets from the fan cavity 230, so that after the water baffle receives water droplets, the water droplets can fall freely into the receiving groove by gravity, preventing the water droplets from flowing to other places. The receiving groove collects the water droplets and connects them to the second opening, allowing the accumulated water to flow into the fan cavity from the second opening. This ensures that the accumulated water does not accumulate in the receiving groove, thus preventing excessive water overflow and affecting the internal safety.

[0033] Specifically, when the fan in the fan chamber 230 starts and the fan blades rotate, the fan chamber 230 becomes a negative pressure chamber. Outdoor air enters the compressor chamber 240 through the air inlet 260, flows over the surface of the electrical control box 100, enters the housing 111 through the first opening 112, and then enters the fan chamber 230 from the air outlet 250. This increases the airflow on the surface of the electrical control box 100 and improves the heat dissipation of the electrical control box 100.

[0034] Preferably, by placing the electronic control box 100 on the air duct path formed by the air inlet 260, the compressor cavity 240, the air outlet 250 and the fan cavity 230 connected in series, the heat dissipation airflow is forced to flow over the surface of the electronic control box 100, directly carrying away the heat of the electronic components and significantly improving the heat dissipation efficiency; at the same time, the airflow in the air duct dynamically isolates the external high-temperature environment, avoiding the local accumulation of heat in the compressor cavity 240, ensuring the stable operation of the electronic control box 100 under high-temperature conditions, and extending the service life of the components.

[0035] Preferably, the first water-blocking component 110 intercepts condensate splashed in from the air outlet 250 in the opposite direction, preventing water from flowing back into the control box 100 along the air duct; the second water-blocking component 120 blocks rainwater from entering from the air inlet 260 in the forward direction, forming a two-way waterproof barrier. While maintaining unobstructed airflow for heat dissipation in the air duct, it prevents liquid water from contacting the internal components of the control box 100, thus balancing efficient heat dissipation and comprehensive waterproofing requirements, and reducing the risk of short circuits in humid and hot environments. Simultaneously, the double-sided protection of the first and second water-blocking components 110 and 120 ensures that water droplets, whether from the outside or inside the fan cavity 230, can be better blocked from directly entering the surface of the control box 100, thereby improving the waterproofing effect inside the control box 100 and preventing the electronic components on the control box 100 from getting damp and affecting normal operation.

[0036] Specifically, the first water-blocking component 110 also includes: a housing 111, which is connected to the wind-blocking upright plate 210 and surrounds the air outlet 250 to form an accommodating space; the housing 111 is also provided with a first opening 112, which is connected to the compressor cavity 240.

[0037] Preferably, the housing 111 surrounds the air outlet 250 to form a containment space, confining splashed water to a localized area and preventing water droplets from spreading to the compressor cavity 240. The first opening 112 connects to the compressor cavity 240 to maintain the continuity of airflow in the duct, ensuring that the heat dissipation airflow flows through the electrical control box 100 without obstruction. At the same time, the containment space physically isolates the air outlet 250 from the electrical control box 100, blocking the direct splashing path of water and achieving zoned management of heat dissipation and waterproofing spaces. Furthermore, the complete coverage of the housing 111 ensures that even if water droplets enter from the air outlet, they can be fully received by the housing 111, preventing water droplets from directly entering the surface of the electrical control box 100 and affecting the electronic components on the electrical control box 100. This prevents the electronic components from getting damp and improves their safety.

[0038] Specifically, a second opening is provided at the bottom of the containment space; the second opening is connected to the ventilation fan chamber 230; wherein, the second opening is used to drain water from the containment space.

[0039] Specifically, the second opening is integrally formed with the housing 111 and is located at the bottom of the receiving space. The second opening corresponds to the position of the housing 111 that receives water droplets, so that after the water droplets are received by the housing 111, they can be better discharged directly by the second opening. The shape of the second opening can be an opening facing the fan cavity 230, so that after the water droplets form a flow or accumulated water enters the second opening, it can be directly discharged into the fan cavity 230, so that water will not accumulate inside, ensuring the safety of the internal electronic components and thus improving the waterproof capability.

[0040] Preferably, the second opening at the bottom of the containment space directs the collected water to the fan cavity 230, and the fan cavity 230 drainage system quickly discharges the accumulated water, preventing water from overflowing or seeping into the compressor cavity 240. The flow guidance process does not interfere with the main airflow path of the duct, maintains the heat dissipation efficiency of the electrical control box 100 area, and eliminates the risk of moisture and corrosion caused by water retention.

[0041] Specifically, the air outlet 250 and the first opening 112 are offset.

[0042] Preferably, the staggered design of the air outlet 250 and the first opening 112 forms a non-linear airflow channel, forcing the airflow to generate turbulence within the containment space to improve heat dissipation uniformity. Simultaneously, the staggered structure prevents water from splashing directly through the first opening 112 from the air outlet 250, allowing only a detour. Utilizing the principle of inertial separation, water droplets collide with the wall of the housing 111 and fall, significantly reducing the probability of water droplets entering the compressor cavity 240. Furthermore, the staggered design of the air outlet 250 and the first opening 112 further protects the electronic components on the control box 100. The staggered design ensures that most of the incoming water droplets are blocked, thus providing better protection for the control box 100.

[0043] Specifically, the second water-blocking assembly 120 also includes: a first blocking member 121, which is disposed near the air inlet 260; and a second blocking member 122, which is disposed near the side of the electrical control box 100.

[0044] Preferably, the first blocking member 121 directly intercepts large-diameter water droplets carried by the high-speed airflow from the air inlet 260, while the second blocking member 122 provides secondary protection against atomized water vapor bypassing the first blocking member 121. This dual-stage water-blocking structure decomposes the impact energy of the water flow. Together, they form a gradually narrowing guide channel, guiding the airflow to adhere to the surface of the control box 100 to enhance heat dissipation. Simultaneously, they guide the water droplets to the bottom of the side plate 220 for discharge, preventing the formation of a water film on the surface of the control box 100 and thus avoiding interference with heat dissipation. By using the first blocking member 121 and the second blocking member 122 to collaboratively block the entry of water droplets, the water droplets are better prevented from directly contacting the electronic components on the control box 100, thus avoiding any impact on their normal operation. This also prevents the electronic components on the control box 100 from getting damp, improving the waterproof performance of the control box 100 and extending its service life.

[0045] Specifically, the air inlet 260 is provided with multiple air inlets 261, and the first blocking member 121 also includes: the first blocking member 121 is provided with multiple ventilation openings 123; and the multiple ventilation openings 123 are staggered with the multiple air inlets 261.

[0046] Preferably, the vent 123 and the air inlet 261 are misaligned to form a labyrinthine airflow path, which prolongs the collision path of water droplets in the water-blocking component and causes the water droplets to fall by consuming kinetic energy through multiple collisions.

[0047] Specifically, the first blocking member 121 is inclined relative to the second blocking member 122; the second blocking member 122 is perpendicular to the bottom surface of the electrical control box 100.

[0048] Preferably, the first blocking member 121 is tilted to guide the airflow upwards around the top of the electronic control box 100, avoiding direct blowing on the sensitive areas of the electronic components; the tilted surface causes the collision water droplets to slide down the inclined surface to the edge of the side plate 220 for discharge; the second blocking member 122 is vertically set to form an end water barrier, intercepting the rebound water droplets and guiding the airflow to flow evenly along the bottom of the electronic control box 100, enhancing the heat dissipation effect of the high-heat components at the bottom, and establishing gravity drainage guidance.

[0049] Specifically, the first blocking member 121 and the second blocking member 122 are arranged in a V-shape.

[0050] Specifically, the first blocking member 121 is inclined, and the second blocking member 122 is vertically arranged. One end of the two is connected to form a V-shape. The projection of the multiple vents 123 on the first blocking member 121 can directly fall onto the second blocking member 122. Thus, even if some water droplets enter through the air inlet 261, they are partially blocked by the structure of the multiple vents 123 and the multiple air inlets 261. Furthermore, the water droplets that enter through the multiple vents 123 can be blocked by the second blocking member 122, preventing water droplets from entering the electrical control box 100 and affecting the electronic components on the electrical control box 100, thereby affecting the use of the electrical control box 100. This arrangement can better protect the electronic components on the electrical control box 100 and improve its service life.

[0051] Preferably, by setting the first blocking member 121 and the second blocking member 122 in a V-shape, the rainwater from the outside can be better blocked when it enters the interior through the air inlet 260. The V-shape setting allows the rainwater to be blocked on the second blocking member 122, and the contact area of ​​the inclined surface is larger, which can better receive the rainwater, thereby improving the overall waterproof performance.

[0052] Specifically, the air outlet 250 is provided with multiple air outlets 251; each air inlet 261 and each air outlet 251 is provided with a shielding component, which shields but does not seal each air inlet 261 and each air outlet 251.

[0053] Preferably, shielding is used to prevent water from splashing in directly, but it does not block the air intake and exhaust, thus making the overall protection stronger and achieving a better waterproof effect.

[0054] This utility model also provides an air conditioner outdoor unit 200, which includes: an outdoor unit body; and an electrical control box 100 as described above is provided inside the outdoor unit body.

[0055] The air conditioner outdoor unit 200 in this embodiment includes an outdoor unit body, and the electrical control box 100 is disposed in the outdoor unit body. Therefore, it has all the beneficial effects of the electrical control box 100 in any embodiment of this utility model, which will not be repeated here.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it.
