Description

Technical Field

[0001] This application relates to the field of air conditioning technology, such as an outdoor unit for an air conditioner and an air conditioner. Background Technology

[0002] Currently, reactors in air conditioner power circuits serve to filter AC harmonics and regulate voltage rise and fall. By filtering out AC components, they improve the power factor and increase DC power efficiency. However, reactors generate a significant amount of heat during operation, causing their own temperature to rise continuously. When the reactor temperature becomes too high, it can cause the compressor to reduce its frequency and power output, and may even lead to damage and hazard. Therefore, to improve the overall reliability of the air conditioner, it is necessary to provide cooling for the reactor.

[0003] In household air conditioning products, the reactor is usually fixed inside the outdoor unit of the air conditioner with a metal partition facing the compressor. An axial fan located on the other side of the metal partition rotates to form eddy currents, which can dissipate heat from the partition, thereby indirectly cooling the reactor.

[0004] In implementing the embodiments of this disclosure, it has been found that at least the following problems exist in the related art: the heat dissipation efficiency of existing methods for heat dissipation of reactors is low. Summary of the Invention

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0026] Combination Figures 1 to 4As shown, this embodiment of the present disclosure provides an outdoor unit for an air conditioner, including: a fan compartment 100, a compressor compartment 200, a partition 10 disposed between the fan compartment 100 and the compressor compartment 200, and a reactor 20. The partition 10 is provided with a hollow portion 101, and a blown plate radiator 30 is embedded in the hollow portion 101. The reactor 20 and the blown plate radiator 30 are in thermal contact.

[0027] In the above embodiment, the fan nacelle and compressor nacelle are separated by a partition. The blown plate radiator makes thermal contact with the reactor and exchanges heat. The blown plate radiator is embedded in the perforated part of the partition. The airflow from the fan nacelle acts on the blown plate radiator, dissipating heat and cooling it, thereby cooling the reactor and improving its heat dissipation efficiency. Furthermore, the perforated part of the partition helps protect the blown plate radiator, effectively preventing damage. Optionally, the blown plate radiator can be made of aluminum, which improves the thermal conductivity between it and the reactor, further enhancing the reactor's heat dissipation efficiency. Additionally, the heat dissipation area of ​​the blown plate radiator is larger than the contact area between the reactor and the blown plate radiator. This further improves the reactor's heat dissipation efficiency.

[0028] Combination Figure 1 As shown, an axial fan 1001 is installed inside the fan nacelle 100, and a compressor 2002 is installed inside the compressor nacelle 200. A blown plate radiator 30 is installed vertically, and a reactor 20 is located on the side of the blown plate radiator 30 facing the compressor 2002. This not only allows the reactor to perform its function effectively but also enables the axial fan to dissipate heat from the blown plate radiator, thereby achieving heat dissipation and cooling of the reactor.

[0029] Optionally, combined Figure 1 and Figure 2 As shown, the perforated portion 101 is located on the upper part of the partition plate 10. This not only facilitates the operation of the reactor, but also allows for better utilization of the axial fan to dissipate heat from the blown plate radiator, thus improving the heat dissipation efficiency of the blown plate radiator.

[0030] Optionally, the blown-expanded plate radiator and the partition are detachably connected. Alternatively, the blown-expanded plate radiator and the partition can be connected by fasteners. This facilitates the assembly and disassembly of the blown-expanded plate radiator and the partition. For example, blown-expanded plate radiators are generally made of aluminum and are thin and easily deformed; if the blown-expanded plate radiator is damaged, it can be disassembled and replaced. Furthermore, the blown-expanded plate radiator and the partition can be a single piece. This improves the installation stability of the blown-expanded plate radiator.

[0031] Optionally, the blown plate radiator includes an interconnected condenser end and an evaporator end, both filled with a heat transfer medium. The reactor is in thermal contact with the evaporator end of the blown plate radiator. In practical applications, the reactor exchanges heat with the evaporator end of the blown plate radiator. The liquid heat transfer medium in the evaporator end is heated, its temperature rises, it vaporizes, and flows towards the condenser end. An axial fan condenses and cools the hotter gaseous heat transfer medium in the condenser end of the blown plate radiator. The gaseous heat transfer medium becomes liquid and flows towards the evaporator end for the next heat dissipation cycle, achieving the purpose of cooling the reactor. The evaporator end can be understood as the part of the blown plate radiator that is in direct contact with the reactor, and the condenser end can be understood as the part of the blown plate radiator excluding the evaporator end.

[0032] The blown plate radiator provided in this embodiment has a closed heat transfer circuit that is evacuated and filled with heat transfer medium. The one-piece blown plate radiator has fewer welding points, which reduces the risk of heat transfer medium leakage, reduces the cost of the outdoor unit of the air conditioner, and improves the reliability of the outdoor unit of the air conditioner during packaging, transportation and operation.

[0033] Optionally, the blown plate radiator 30 includes: a first surface, which is a convex surface provided with a heat transfer circuit, the heat transfer circuit being filled with a heat transfer medium; and a second surface, which is a plane, wherein the reactor 20 is in thermal contact with the second surface of the blown plate radiator 30.

[0034] To better demonstrate the heat transfer circuit, Figure 3 This is a flipped, inflatable radiator. In practical applications, the reactor can be installed... Figure 3 The area shown is within the dashed box.

[0035] The first surface of the blow-out plate radiator faces the fan nacelle. The airflow generated by the axial fan acts on the convex surface where the heat transfer circuit is located, which helps the axial fan to enhance heat dissipation from the convex surface. Here, "the first surface is a convex surface with a heat transfer circuit" can be understood as: the area with the heat transfer circuit on the first surface protrudes from the area without the heat transfer circuit on the first surface, and the first surface is uneven.

[0036] The second side of the blown plate radiator faces the compressor compartment. The planar structure of this second side facilitates close contact and fixation with the reactor. This not only improves the heat conduction efficiency between the reactor and the blown plate radiator but also enhances the connection stability between them.

[0037] Optionally, the reactor is in direct contact with the second surface of the blown plate radiator, exchanging heat through contact heat transfer. Optionally, the reactor is detachably connected to the blown plate radiator. For example, the reactor and the blown plate radiator are connected by fasteners. Optionally, the blown plate radiator has a clearance for connection with the fasteners. This helps prevent the fasteners from penetrating the heat transfer circuit and causing leakage at the connection between the fasteners and the blown plate radiator.

[0038] Optionally, the blown plate radiator 30 includes: an upper part having an upper heat transfer circuit; and a lower part having a lower heat transfer circuit and connected to the upper heat transfer circuit, wherein the reactor 20 is in thermal contact with the lower part of the blown plate radiator 30.

[0039] When the blown plate radiator is vertically installed, the portion above the horizontal symmetrical dividing line of the blown plate radiator is considered the upper part, and the portion below the horizontal symmetrical dividing line is considered the lower part. This can be understood as the upper part of the blown plate radiator corresponding to the aforementioned condenser end, and the lower part corresponding to the aforementioned evaporator end. The condenser end and evaporator end are connected, and the reactor is located at the lower part of the blown plate radiator, i.e., the evaporator end. Furthermore, the positioning of the upper and lower heat transfer loops facilitates gas-liquid separation of the heat transfer medium within the heat transfer loops. The gaseous heat transfer medium moves upward, while the liquid heat transfer medium flows downward under gravity and is stored in the lower heat transfer loop. The heat transfer medium in the lower heat transfer loop undergoes sufficient heat exchange with the reactor, which helps improve the heat dissipation efficiency of the reactor.

[0040] In practical applications, the lower part of the blown plate radiator exchanges heat with the reactor. The heat transfer medium in the lower heat transfer circuit is heated and vaporized. The gaseous heat transfer medium rises along the lower heat transfer circuit to the upper heat transfer circuit. The heat transfer medium in the upper heat transfer circuit is cooled by natural heat dissipation on both sides of the upper part of the blown plate radiator and by axial flow fan. The gaseous heat transfer medium condenses into a liquid heat transfer medium. Under the action of gravity, the liquid heat transfer medium flows into the lower heat transfer circuit of the blown plate radiator, forming a heat dissipation circulation circuit. This facilitates continuous circulation of heat transfer medium in the blown plate radiator to cool the reactor.

[0041] Optionally, combined Figure 3 As shown, the upper part includes multiple first rolling points 306, and the lower part includes multiple second rolling points 307. The upper part is provided with a first rolling point group, which includes at least an adjacent first row of rolling points and a second row of rolling points, and the rolling points in the first row of rolling points are symmetrically arranged with the rolling points in the second row of rolling points; and / or, the lower part is provided with a second rolling point group, which includes at least an adjacent third row of rolling points and a fourth row of rolling points, and the rolling points in the third row of rolling points are symmetrically arranged with the rolling points in the fourth row of rolling points.

[0042] The first row of rolling points includes multiple first rolling points, and the second row of rolling points includes multiple first rolling points. The first rolling points in the first row and the first rolling points in the second row are arranged symmetrically. This helps to reduce the resistance during the upward movement of the gaseous heat transfer medium, and the liquid heat transfer medium formed after cooling can quickly flow back to the lower heat transfer circuit in the upper heat transfer circuit to perform the next heat exchange cycle with the reactor.

[0043] Optionally, the multiple first rolling points in the first row of rolling points are evenly spaced. Similarly, the multiple first rolling points in the second row of rolling points are also evenly spaced. This not only facilitates the flow of the heat transfer medium but also promotes its uniform distribution.

[0044] This disclosure does not limit the number or number of rows of first rolling points in the first rolling point group. For example, the first rolling point group may include M rows of first rolling points, where M is greater than 2.

[0045] The third row of rolling points includes multiple second rolling points, and the fourth row of rolling points also includes multiple second rolling points. The second rolling points in the third row and the second rolling points in the fourth row are arranged symmetrically. This not only helps to reduce the resistance during the upward movement of the gaseous heat transfer medium, but also allows the liquid heat transfer medium to quickly flow back to the lower heat transfer loop under the action of gravity.

[0046] Optionally, the multiple second rolling points in the third row of rolling points are evenly spaced. Similarly, the multiple second rolling points in the fourth row of rolling points are also evenly spaced. This not only facilitates the flow of the heat transfer medium but also promotes its uniform distribution.

[0047] This disclosure does not limit the number or number of rows of second rolling points in the second rolling point group. For example, the second rolling point group may include N rows of second rolling points, where N is greater than 2.

[0048] Optionally, combined Figure 3 As shown, the vertical flow path 308 of the upper heat transfer circuit is directly connected to the vertical flow path 309 of the lower heat transfer circuit. This not only facilitates the upward movement of the gaseous heat transfer medium but also promotes the rapid reflux of the liquid heat transfer medium.

[0049] Optionally, the area of ​​the first rolling point 306 is greater than or equal to the area of ​​the second rolling point 307. The number of first rolling points is less than or equal to the number of second rolling points. When the area of ​​the first rolling point is greater than the area of ​​the second rolling point, and the number of first rolling points is less than the number of second rolling points, the length of the flow path of the heat transfer medium in the lower heat transfer loop is greater than the length of the flow path in the upper heat transfer loop. This increases the storage capacity of the heat transfer medium in the lower heat transfer loop, ensuring sufficient heat exchange between the heat transfer medium and the reactor, which is beneficial to improving the heat dissipation efficiency of the reactor.

[0050] Optionally, the blown plate radiator 30 is bent and includes a bent connection of: a first heat dissipation part 301, which is embedded in the hollow part 101 of the partition; and a second heat dissipation part 302, which is connected to the compressor housing 2002, wherein the reactor 20 is in thermal contact with the first heat dissipation part 301 of the blown plate radiator 30.

[0051] The heat transfer circuits within the first and second heat dissipation sections are interconnected. The first and second heat dissipation sections enclose a space where the reactor makes thermally conductive contact with the first heat dissipation section, while the second heat dissipation section does not contact the reactor. The first heat dissipation section directly contacts the reactor, receiving its heat, and the heat is simultaneously dissipated through both sections, thus achieving heat dissipation for the reactor and improving its heat dissipation efficiency. Furthermore, the first heat dissipation section is embedded in the perforated portion of the partition, allowing for heat transfer through contact with the partition. The partition expands the heat dissipation area of ​​the first heat dissipation section. The partition not only provides natural heat dissipation but also enhances heat dissipation through an axial fan, thus also contributing to the reactor's heat dissipation efficiency. In addition, the connection between the second heat dissipation section and the compressor housing improves the stability of the blown plate heat sink.

[0052] Optionally, the connection between the first heat dissipation section and the second heat dissipation section is arc-shaped. In this way, the heat transfer circuit in the first heat dissipation section is connected to the heat transfer circuit in the second heat dissipation section, which is beneficial to the flow of the heat transfer medium in the first and second heat dissipation sections.

[0053] Optionally, combined Figure 3 As shown, the heat transfer circuit includes: a first heat dissipation circuit 3011 disposed in the first heat dissipation part 301, and a second heat dissipation circuit 3021 disposed in the second heat dissipation part 302 and connected to the first heat dissipation circuit 3011, wherein the lower edge of the first heat dissipation circuit 3011 is lower than the lower edge of the second heat dissipation circuit 3021.

[0054] Here, "the lower edge of the first heat dissipation circuit is lower than the lower edge of the second heat dissipation circuit" can be interpreted as follows: Figure 3 As shown, the heat transfer medium, after cooling and becoming liquid, continues to flow downwards from the second heat dissipation circuit to the first heat dissipation circuit under the action of gravity, causing the liquid heat transfer medium to concentrate in the first heat dissipation circuit, thus better dissipating heat for the reactor.

[0055] In practical applications, the gaseous heat transfer medium in the first heat dissipation loop moves upward and diffuses into the second heat dissipation loop. The gaseous heat transfer medium is cooled and condensed through both loops. The condensed liquid heat transfer medium then flows back and concentrates in the lower part of the first heat dissipation loop. The reactor is in thermal contact with the lower part of the first heat dissipation section. In this way, the concentrated liquid heat transfer medium undergoes a rapid phase change during heat exchange with the reactor, vaporizing to form a gaseous heat transfer medium that moves upward. Then, after natural heat dissipation from both sides of the blown plate radiator and enhanced cooling by the axial fan, it condenses back into a liquid heat transfer medium and flows back, forming a heat dissipation circulation loop.

[0056] The second heat dissipation circuit expands the heat dissipation area of ​​the first heat dissipation circuit. At the same time, the liquid heat transfer medium in the second heat dissipation circuit flows back to the lower part of the first heat dissipation circuit, and exchanges heat with the liquid heat transfer medium in the first heat dissipation circuit to the reactor. This helps to quickly eliminate the overheating phenomenon of the reactor and improves the heat dissipation efficiency of the reactor.

[0057] Optionally, the blown plate radiator is provided with multiple air vents.

[0058] The air generated by the axial fan in the fan nacelle enters the compressor nacelle through the air vents, cooling the air inside the compressor nacelle and also cooling the blown plate radiator, thus accelerating the air circulation on the surface of the blown plate radiator.

[0059] Air vents are located in areas of the blow-up plate radiator where no heat transfer circuit is provided. Some or all of the heat transfer circuits are arranged around the air vents. In this way, the airflow generated by the axial fan passes through the air vents, accelerating the dissipation of heat transfer fluid within the heat transfer circuit around the air vents, thus improving the heat dissipation efficiency of the heat transfer fluid around the air vents.

[0060] Combination Figure 3 As shown, the vents are positioned to avoid the reactor 20. If the airflow from the axial fan directly impacts the reactor, it can easily disrupt its stability and cause it to fall. By using vents to avoid direct airflow from the axial fan, the reactor's installation stability is improved. Optionally, the shape of the vents may match the shape of the first and / or second rolling points.

[0061] Optionally, combined Figure 3As shown, the first heat dissipation part 301 is provided with a first air hole group 303 and a second air hole group 304. The first air hole group 303 is close to the upper edge of the first heat dissipation part 301, and the second air hole group 304 is close to the bend between the first heat dissipation part 301 and the second heat dissipation part 302. The second heat dissipation part 302 is provided with a third air hole group 305. The upper air hole in the third air hole group 305 is close to the upper edge of the second heat dissipation part 302, and the lower air hole in the third air hole group 305 is close to the lower edge of the second heat dissipation part 302.

[0062] The first group of air vents 303 and the second group of air vents 304 are located around the installation position of the reactor 20. The first group of air vents 303 is located above the reactor 20, and the second group of air vents 304 is located on one side of the reactor 20. Airflow passing through the vents of the first and second groups of air vents not only cools the blown plate radiator but also acts on the reactor and the surrounding air, accelerating airflow around the reactor and improving its heat dissipation efficiency. Airflow passing through the vents of the third group of air vents further accelerates airflow around the second heat dissipation section, improving its heat dissipation efficiency.

[0063] In practical applications, the hottest gaseous heat transfer medium is located at the top of the first heat dissipation circuit of the first heat dissipation unit, resulting in excessively high temperatures at the top of the first heat dissipation unit. The first air vent group is located near the upper edge of the first heat dissipation unit. Airflow through the vents of the first air vent group accelerates air circulation on the surface of the first heat dissipation unit. After the first heat dissipation unit exchanges heat with the surrounding air, the temperature of the surrounding air rises, and the hotter air is then blown away from the first heat dissipation unit by the airflow, thereby improving the heat dissipation efficiency of the first heat dissipation unit. In this way, overheating at the top of the first heat dissipation unit can be eliminated to the greatest extent possible.

[0064] Furthermore, the bend between the first and second heat dissipation sections faces away from the air outlet of the outdoor unit, resulting in slow heat dissipation. By installing a second set of air vents near the bend between the first and second heat dissipation sections, airflow through the vents of the second set accelerates air circulation on the surface of the first heat dissipation section and around the second heat dissipation section. After heat exchange between the first heat dissipation section and the surrounding air, the temperature of the surrounding air rises, and the warmer air is then blown away from the first heat dissipation section by the airflow, thereby improving the heat dissipation efficiency of the first heat dissipation section. In this way, the heat dissipation efficiency at the bend between the first and second heat dissipation sections can be accelerated, eliminating localized overheating at the bend.

[0065] Optionally, the lower vent of the second vent group 304 is located near the lower edge of the first heat dissipation section 301. This not only helps to expand the airflow area and improve the heat dissipation efficiency of the first heat dissipation section, but also allows for continuous heat dissipation to the lower part of the first heat dissipation section through the lower vent of the second vent group, extending the phase change time of the liquid heat transfer medium in the first heat dissipation circuit of the first heat dissipation section, and enabling sufficient heat exchange between the liquid heat transfer medium and the reactor.

[0066] The upper vent of the third vent group 305 is close to the upper edge of the second heat dissipation part 302, and the lower vent of the third vent group 305 is close to the lower edge of the second heat dissipation part 302. In this way, it is not only conducive to eliminating the overheating phenomenon at the top of the second heat dissipation part, but also conducive to maintaining the temperature of the lower part of the second heat dissipation part, preventing local overheating of the lower part of the second heat dissipation part when there is no heat transfer circuit in the lower part of the second heat dissipation part and it cannot cool down.

[0067] Optionally, the outdoor unit of the air conditioner also includes: folded fins 40, which are thermally connected to the first side of the blown plate radiator 30.

[0068] Folded fins increase the heat dissipation area of ​​the blown plate radiator, thus improving its heat dissipation efficiency. In practical applications, a portion of the folded fins adheres to the first surface of the blown plate radiator, allowing heat to be transferred from the radiator to the folded fins and then dispersed. The airflow generated by the axial fan acts on the folded fins, cooling them down.

[0069] Alternatively, the folding fins can be bow-shaped, wavy, or S-shaped. Furthermore, aluminum is the preferred material for the folding fins, and they are formed by stamping. Figure 4 The diagram shows folded fins in a bow shape.

[0070] Optionally, the folded fins are thermally connected to the heat transfer circuit of the blown plate radiator. That is, the folded fins are in direct contact with the area of ​​the blown plate radiator where the heat transfer circuit is located. This helps to improve the heat exchange efficiency between the folded fins and the blown plate radiator.

[0071] In practical applications, the folding fins can optionally be detachably connected to a partition. Alternatively, the folding fins can optionally be detachably connected to a blown plate radiator. Alternatively, the folding fins can optionally be detachably connected to the housing of the outdoor unit of the air conditioner. The size of the folding fins can be selected according to actual needs.

[0072] Optionally, combined Figure 1 and Figure 2 As shown, the edge of the blow-blown plate radiator 30 is provided with a fixed frame 50.

[0073] The blown-out plate radiator 30 is secured by a fixed frame 50, which surrounds the edge of the blown-out plate radiator 30. This not only supports the blown-out plate radiator but also improves its stability, preventing damage during transportation, packaging, and operation. The blown-out plate radiator is detachably connected to the fixed frame. Optionally, the fixed frame is embedded in the perforated portion of the partition and detachably connected to the inner wall of the perforated portion. Optionally, the fixed frame is detachably connected to the outer wall of the perforated portion of the partition. Optionally, one side of the fixed frame is detachably connected to the compressor housing.

[0074] This disclosure provides an air conditioner, including the outdoor unit of the air conditioner as described in the above embodiments.

[0075] Air conditioners with outdoor units use a blown plate radiator to dissipate heat from the reactor, which improves the stability and safety of the reactor during operation and enhances the reliability of the air conditioner.
