Description

Technical Field

[0001] This utility model belongs to the technical field of air conditioning and refrigeration equipment, specifically an air conditioning refrigeration and heat dissipation device. Background Technology

[0002] In air conditioning systems, the condenser plays a crucial role in heat dissipation and refrigerant liquefaction. When high-temperature gaseous refrigerant flows through the winding pipes inside the condenser, a fan on one side of the pipes accelerates the airflow, causing the condenser to quickly dissipate heat. This rapidly cools and liquefies the high-temperature gaseous refrigerant, significantly improving the heat exchange efficiency between the condenser and the outside air. To further enhance heat dissipation, heat dissipation fins are typically integrally molded onto the pipes. However, this design also introduces new problems: condensers with heat dissipation fins have a complex structure, are prone to dust accumulation, and are difficult to clean.

[0003] To address this issue, related technologies have been continuously explored. The patent, authorized under CN222298046U and published on 2025-01-03, is titled "A Heat Dissipation Mechanism for an Air Conditioning Refrigeration Equipment." While this patent solves the problem of "when cleaning is required, the connection between the upper fixing structure and the fixing plate can be released, and the connection between the connecting seat and the fixing groove on the bottom wall of the housing can be released, allowing the heat dissipation component to be moved laterally away from the condenser, making disassembly and assembly convenient, facilitating cleaning of the heat sink and the outer wall of the condensing pipe, and reducing cleaning difficulty," the connections of this device are all made with bolts or fasteners. Repeated disassembly and assembly can easily cause wear and tear on the bolts or fasteners. Furthermore, other tools are needed to assist in disassembly, which is time-consuming and labor-intensive. Therefore, it is difficult to achieve the desired effect in practical applications. Summary of the Invention

[0006] The upper and lower inner walls of the air conditioner outdoor unit casing are provided with two slot plates. The upper and lower ends of the fixing frame are provided with insert plates corresponding to the slot plates. Each insert plate is inserted into the corresponding slot plate. An electric fan is provided on the inner wall of the fixing frame. Reinforcing mechanisms are provided on both side walls of the fixing frame.

The limiting protrusion in the sliding hole is slidably limited by the sliding groove on the threaded rod. The threaded rod is threadedly connected to the inner threaded sleeve. The inner threaded sleeve is rotatably connected to the side wall of the fixing frame through the bearing. The other end of the threaded rod is rotatably connected to the top plate. The top plate is abutted against the inner side wall of the air conditioner outdoor unit housing.

[0009] The heat dissipation mechanism includes two connecting plates, two plug-in plates, two plug-in units, and multiple heat sinks;

[0010] Multiple heat sinks are fixed between the two connecting plates. The multiple heat sinks are evenly distributed and each heat sink has a groove for use with the condensing pipe. Each groove is fitted to the condensing pipe. The upper connecting plate has two plug-in units and the lower connecting plate has two plug-in plates. The bottom of the air conditioner outdoor unit casing has a sliding groove that matches the two plug-in plates. Each sliding groove is plugged into the corresponding plug-in plate.

[0011] Each of the aforementioned plug-in units includes a spring, a pin, and two through holes;

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. High-efficiency heat dissipation and improved cooling performance: This device significantly reduces thermal resistance through the interference fit design of the condenser pipe and heat sink, forming a highly efficient heat conduction path. At the same time, the electric fan on the inner wall of the mounting bracket accelerates airflow, enhances the convective heat dissipation effect, and promotes the rapid cooling and liquefaction of the high-temperature gaseous refrigerant, significantly improving the heat dissipation efficiency of the air conditioning refrigeration system, thereby optimizing cooling performance, reducing energy consumption, and ensuring the long-term stable operation of the air conditioner.

[0015] 2. Convenient installation and maintenance, reducing operating costs: During installation, the mounting bracket is initially positioned by inserting the plug plate into the slot plate of the air conditioner outdoor unit casing, and then the reinforcement mechanism is used to easily complete the stable installation; the heat dissipation mechanism adopts a double plug structure, and the combination of the upper spring and the pin enables quick connection and disassembly without the need for additional tools, avoiding frequent wear and tear on bolts and other connecting parts. This design greatly simplifies the installation and maintenance process, shortens the operation time, reduces labor costs and maintenance difficulty, and improves user convenience.

[0016] 3. Stable and reliable structure, enhancing operational safety: In the reinforcement mechanism, the threaded rod and the internal threaded sleeve are connected by a sliding hole limit design to ensure the fixed frame is securely installed. The anti-slip rubber on the top plate further increases friction, effectively preventing the fixed frame from loosening due to vibration generated during fan operation. This ensures the structural stability of the device during operation, reduces the risk of failure caused by loose parts, extends the service life of the air conditioner outdoor unit, and improves operational safety.

[0017] 4. Modular design facilitates component replacement and upgrades: The heat dissipation mechanism adopts a modular design and is independently connected to the mounting bracket and the air conditioner outdoor unit casing. When the heat sink or condensation pipe is damaged or needs to be upgraded, the corresponding module can be quickly disassembled and replaced without major modifications to the entire outdoor unit structure, reducing maintenance costs and technical barriers, and providing convenience for subsequent product iteration and optimization.

[0018] In summary, this utility model, with its advantages of efficient heat dissipation design, convenient installation and maintenance structure, stable and reliable operation guarantee, and modular upgrade, comprehensively improves the overall performance of the air conditioning refrigeration system, effectively reduces usage costs and maintenance difficulty, and brings users a better, more efficient, and more economical user experience.

The inner threaded sleeve 7 is rotatably connected to the side wall of the fixing frame 3 through the bearing 8. The other end of the threaded rod 6 is rotatably connected to the top plate 9. The top plate 9 is abutted against the inner side wall of the air conditioner outdoor unit housing 1.

[0031] The heat dissipation mechanism includes two connecting plates 12, two insert plates 16, two plug-in units, and multiple heat sinks 11.

[0032] Multiple heat sinks 11 are fixed between the two connecting plates 12. The multiple heat sinks 11 are evenly distributed. Each heat sink 11 has a groove that is used to cooperate with the condensing pipe 10. Each groove is fitted to the condensing pipe 10. The upper connecting plate 12 has two plug-in units, and the lower connecting plate 12 has two plug-in plates 16. The bottom of the air conditioner outdoor unit casing 1 has a sliding groove that matches the two plug-in plates 16. Each sliding groove is plugged into the corresponding plug-in plate 16.

[0033] Each of the said plug-in units includes a spring 14, a pin 15, and two through holes 13;

[0034] The heat dissipation mechanism has two through holes 13 on the upper connecting plate 12. The pin 15 is slidably disposed in the corresponding through hole 13. The spring 14 is fitted on the pin 15. The lower outer wall of the spring 14 is fixedly connected to the inner wall of the through hole 13. The upper inner wall of the spring 14 is fixedly connected to the outer wall of the pin 15. The pin 15 is inserted into the corresponding socket 5.

[0035] Working principle of air conditioning cooling and heat dissipation devices:

[0036] I. Core heat dissipation principle:

[0037] In the air conditioning refrigeration system's circulation process, the compressor first compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant. Then, the high-temperature, high-pressure gaseous refrigerant flows into the condenser pipe 10. When the air conditioner is running, the electric fan 17 installed on the inner wall of the mounting bracket 3 is connected to the internal power supply of the outdoor unit casing 1, and starts operating through power supply, accelerating airflow. In the heat dissipation mechanism, multiple evenly distributed heat sinks 11 are tightly connected to the condenser pipe 10. Each heat sink 11 has a groove that matches the shape of the condenser pipe 10. These grooves fit tightly with the condenser pipe 10 through an interference fit. During assembly, the condenser pipe 10 is precisely embedded into the groove. The close physical contact between them greatly reduces thermal resistance. This close fit allows the condenser pipe 10 to quickly and efficiently conduct heat to the heat sink 11, forming an efficient heat conduction path. Under the action of the fan airflow, the heat sink 11 quickly dissipates the heat transferred from the condenser pipe 10 into the surrounding air, causing the high-temperature gaseous refrigerant to cool and liquefy rapidly. The liquefied refrigerant then flows to the throttling device, where it becomes a low-temperature, low-pressure liquid refrigerant after throttling and pressure reduction. It then enters the evaporator to absorb heat and vaporize, becoming a low-temperature, low-pressure gaseous refrigerant again, which is then drawn into the compressor. This cycle repeats continuously, completing the key heat dissipation link in the air conditioning refrigeration cycle.

[0038] II. Structural stability and installation principle:

[0039] During installation, the mounting bracket 3 is initially positioned by inserting the slot plates 2 on the upper and lower inner walls of the air conditioner outdoor unit housing 1 with the insert plates 4 at the upper and lower ends of the mounting bracket 3. Subsequently, the internal threaded sleeve 7 in the reinforcement mechanism is rotated. Since the internal threaded sleeve 7 is rotatably connected to the side wall of the mounting bracket 3 through the bearing 8, and the threaded rod 6 is threadedly connected to the internal threaded sleeve 7, and the limiting protrusion in the sliding hole slides and the sliding groove on the threaded rod 6 slides and limits, so that the threaded rod 6 can only move horizontally, thereby pushing the top plate 9 (which is equipped with anti-slip rubber) to tightly abut against the inner side wall of the air conditioner outdoor unit housing 1, so as to achieve the stable installation of the mounting bracket 3 and ensure the stability of the fan during operation.

[0040] III. Connection and Maintenance Principles of Heat Dissipation Mechanism:

[0041] The heat dissipation mechanism is initially fixed by inserting the second insertion plate 16 of the lower connecting plate 12 into the sliding groove 2 at the bottom of the air conditioner outdoor unit casing 1. The insertion unit of the upper connecting plate 12 adopts a spring 14 and pin 15 structure. When the pin 15 is pulled out and aligned with the socket 5 on the fixing bracket 3, the pin 15 is released, the spring 14 returns to its original position and pushes the pin 15 into the socket 5, completing the quick connection between the heat dissipation mechanism and the fixing bracket 3. When it is necessary to clean and maintain the heat sink 11 and the condenser pipe 10, the heat dissipation mechanism can be easily disassembled by simply reversing the operation without the need for additional tools, avoiding frequent wear and tear on bolts and other connecting parts, and greatly improving maintenance efficiency.

[0042] Through the precise coordination of its components, the entire device ensures efficient heat dissipation while enabling convenient installation and maintenance, effectively improving the overall performance of the air conditioning refrigeration system.
