Description

Technical Field

[0001] This invention relates to the field of air conditioning outdoor unit technology, and more specifically, to a reactor mounting assembly suitable for high-horsepower inverter top-discharge outdoor units. Background Technology

[0002] The core function of a reactor is to suppress harmonic components in the frequency converter circuit and stabilize the circuit current. This component is generally compatible with frequency converter models of American-style ducted air conditioners with top-mounted air outlets. The installation of the reactor must strictly adhere to three core principles: waterproof and reliable operation, convenient wiring, and avoidance of component interference.

[0003] The current mainstream installation solution is to mount the reactor mounting box on the back of the control board. This solution has the advantages of high space utilization and convenient wiring. However, due to the limitations of installation space and structure, its heat dissipation efficiency, load-bearing stability and waterproof protection performance are all shortcomings. It is only suitable for the installation of small reactors. Summary of the Invention

[0004] The purpose of this invention is to provide a simple and efficient reactor installation component for high-horsepower variable frequency top-discharge outdoor units, which takes into account waterproof performance, heat dissipation performance, and load-bearing performance.

[0005] To achieve the above-mentioned objectives, the technical solution adopted is as follows: An outdoor unit reactor mounting assembly for a top-discharge air conditioner includes a support frame, a reactor mounting base, a reactor top cover, and a sealing cover. The support frame is used to connect to the chassis of the outdoor unit. The reactor mounting base is mounted on the support frame. The reactor top cover spans over the reactor mounting base, and a space is left between the reactor top cover and the reactor mounting base to accommodate the reactor. The bottom of the reactor top cover is connected to the support frame. The sealing cover spans over the reactor top cover, and its bottom is connected to the support frame.

[0006] Preferably, the support frame is a U-shaped support frame, with structures at both ends for connecting to the chassis of the outdoor unit.

[0007] Preferably, the top and one side of the U-shaped support frame have wire holes.

[0008] Preferably, the top of the U-shaped support frame is provided with heat dissipation holes.

[0009] Preferably, the reactor mounting base is fixed to the top of the support frame using a combination of flanged holes and self-tapping screws.

[0010] Preferably, the reactor cover has a U-shaped structure, which spans above the reactor mounting base. The bottom sides of the cover are fixed to the support frame by a combination of flanged holes and self-tapping screws.

[0011] Preferably, the reactor cover has sloping drainage structures on both sides.

[0012] Preferably, the top of the reactor cover is provided with heat dissipation holes.

[0013] Preferably, the sealing cap has a rectangular parallelepiped structure with a hollow bottom.

[0014] Preferably, the sealing cover has heat dissipation holes on its side.

[0015] In the above solutions, the outdoor unit reactor mounting assembly provided by this invention possesses excellent waterproof and heat dissipation performance. Under rainy conditions, the sealing cover can prevent most rainwater from entering the assembly; even if a small amount of rainwater seeps in, it can be quickly discharged through the sloping drainage structure of the reactor cover, effectively avoiding the risk of rainwater accumulation. Simultaneously, combined with the top-discharge outdoor unit's bottom-to-top airflow direction, the airflow can smoothly pass through the heat dissipation holes of the support frame, reactor cover, and sealing cover, forming an efficient heat dissipation channel and ensuring the heat dissipation effect during reactor operation. In actual wiring operations, the reactor connecting wires pass through the wire hole at the top of the support frame, and then exit through the side wire hole to connect with the control board. The overall wiring is simple and neat, greatly improving assembly convenience.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1) The module adopts a double-layer protective structure of a sealing cover and a reactor top cover. The sealing cover can directly block most rainwater from entering the module. For a small amount of rainwater that seeps in, the sloping drainage structure on both sides of the reactor top cover can quickly guide the water flow out. Structurally, this prevents rainwater from accumulating in the reactor's containment space, effectively reducing the risk of rainwater erosion to the reactor and electrical connection parts, and ensuring the stable operation of the module in a humid outdoor environment.

[0017] 2) The components are cleverly integrated with the top-discharge air conditioning outdoor unit's bottom-to-top airflow direction. Heat dissipation holes are opened on the top of the support frame, the reactor's top cover, and the side of the sealing cover, forming a bottom-to-top through-flow heat dissipation channel. During operation, airflow can smoothly pass through the heat dissipation holes of each component, quickly carrying away the heat generated by the reactor, avoiding performance degradation due to localized heat accumulation, significantly improving the reactor's heat dissipation stability, and adapting to the installation requirements of high-power reactors.

[0018] 3) The top and one side of the U-shaped support frame have cable routing holes. The reactor connection wires can be passed through the top cable routing hole and led out through the side cable routing hole to directly connect to the control board, forming an orderly wiring path. This avoids messy and tangled wiring and reduces the risk of interference between the wiring and other components. At the same time, the neat wiring method facilitates quick identification of the wiring route during later inspection and maintenance, reducing the difficulty of assembly and maintenance operations.

[0019] 4) The components are securely connected using a combination of flanged holes and self-tapping screws, ensuring a stable connection. The U-shaped support frame can directly connect to the outdoor unit chassis, adapting to the installation structure of American-style ducted air conditioners with top-discharge air outlets. The U-shaped structure of the reactor mounting base and top cover precisely limits the reactor's installation position, preventing displacement due to vibration during equipment operation and ensuring the stability of the overall structure.

[0024] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention. Example

[0025] This embodiment discloses a reactor mounting assembly 101 for an outdoor unit of a top-discharge air conditioner, such as... Figure 1 , 2 As shown in Figure 3, this is a variable frequency model suitable for American-style ducted air conditioners with top-mounted air outlets, designed to solve the technical problems of poor heat dissipation, weak waterproof performance, and messy wiring in traditional reactor installation schemes.

[0026] The reactor mounting assembly 101 for the outdoor unit of the top-discharge air conditioner includes a support frame 1, a reactor mounting base 2, a reactor top cover 3, and a sealing cover 4. The support frame 1, reactor mounting base 2, reactor top cover 3, and sealing cover 4 are all made of spray-painted sheet metal, using the same material as the machine casing and chassis, specifically DX51D+Z80, which offers good corrosion resistance and surface quality. The support frame 1 is securely connected to the outdoor unit chassis 6 using a combination of flanged holes and self-tapping screws. Wiring holes 7 are provided on the top plane of the U-shaped support frame 1, and similar holes 7 are provided on one side panel for passing reactor connection wires. Simultaneously, heat dissipation holes 8 are evenly distributed on the top plane of the U-shaped support frame 1 to ensure smooth airflow. The reactor mounting base 2 has a rectangular structure, its dimensions matching the top width of the U-shaped support frame 1. The reactor mounting base 2 is fixed to the top of the support frame 1 using a combination of flanged holes and self-tapping screws, and the connection strength meets the load requirements of the outdoor unit's operating vibration. The reactor top cover 3 has a U-shaped structure, and its opening size is adapted to the outer dimensions of the reactor mounting base 2. It can be installed across the reactor mounting base 2, forming a space between them for accommodating the reactor body 5. The reactor top cover 3 is fastened to the side plate of the U-shaped support frame 1 using a combination of flanged holes and self-tapping screws. Sloping drainage structures 9 are provided on both outer walls of the reactor top cover 3 to facilitate the rapid drainage of infiltrated rainwater. Simultaneously, heat dissipation holes 8 are evenly distributed on the top of the reactor top cover 3, staggered from the heat dissipation holes 8 on the top of the support frame 1. The sealing cover 4 has a hollow cuboid structure, its length is the same as the length of the U-shaped support frame 1, and its width is slightly larger than the width of the reactor top cover 3, allowing it to be installed completely across the reactor top cover 3. The sealing cover 4 is fastened to the top plane of the U-shaped support frame 1 using a combination of flanged holes and self-tapping screws. Long, narrow heat dissipation holes 8 are evenly spaced on both sides of the sealing cover 4, forming a through-type heat dissipation channel with the heat dissipation holes 8 of the reactor top cover 3 and the support frame 1. The flanged holes are located on the lugs of the chassis and the U-shaped support frame 1.

[0027] During assembly, first place the U-shaped support frame 1 in the preset installation position on the outdoor unit chassis 6, using a combination of flanged holes and self-tapping screws to ensure there is no loose gap between the support frame 1 and the chassis. Next, place the reactor mounting base 2 on the top plane of the U-shaped support frame 1 and screw in the self-tapping screws to secure it. Then, install the reactor body 5 in the preset area of ​​the reactor mounting base 2. Pass the reactor's connecting wire through the wire hole 7 on the top of the U-shaped support frame 1 into the component's interior, completing the wiring to the reactor. Then, lead the connecting wire out from the wire hole 7 on the side plate of the support frame 1 and directly connect it to the outdoor unit's control board. Place the U-shaped reactor top cover 3 over the reactor and screw in the self-tapping screws to tighten it, ensuring the reactor is stably confined within the receiving space. Finally, place the sealing cover 4 over the reactor top cover 3 and screw in the self-tapping screws to secure it.

[0028] The waterproof performance of the assembled components was verified. After continuous spraying under simulated heavy rain conditions, the sealing cover 4 effectively blocked most of the rainwater intrusion. The small amount of rainwater that did seep in was completely discharged through the sloping drainage structure 9 of the reactor top cover 3. There was no water accumulation on the reactor body 5 and the wiring area. During the heat dissipation performance verification, under the rated operating conditions of the outdoor unit, the top-discharge outdoor unit generated an airflow from bottom to top. The airflow passed through the heat dissipation holes 8 of the support frame 1, the reactor top cover 3, and the sealing cover 4 in sequence, forming an efficient heat dissipation channel. The reactor operating temperature remained within a stable range, and the temperature was significantly lower than that of the traditional installation scheme, meeting the heat dissipation requirements of high-power reactors.
