Description

Technical Field

[0001] This utility model relates to the field of condenser technology, and in particular to a heat dissipation structure for a refrigerator condenser. Background Technology

[0002] The refrigerator condenser is a key component of the refrigeration system. Its function is to release heat from the high-temperature, high-pressure gaseous refrigerant discharged from the compressor and condense it into a liquid state, completing the heat exchange process. In existing technology, household or small refrigerators often use an external condenser structure, in which the condenser coils are arranged in an "S" or serpentine shape at the back of the refrigerator, and heat dissipation is achieved through natural air convection.

[0003] However, heat dissipation relying on natural air convection has limited heat exchange efficiency and is prone to problems such as slow heat dissipation, increased condensation pressure, and increased system energy consumption. Although some products improve heat exchange by adding electric fans for forced ventilation, this also leads to side effects such as increased energy consumption, increased noise, and more complex control systems, making them unsuitable for application scenarios with high requirements for energy saving, quiet operation, and low cost. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a refrigerator condenser heat dissipation structure, which aims to improve the heat exchange efficiency of condensers that rely on natural heat dissipation, while the heat dissipation method of electric fans leads to increased energy consumption and costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A refrigerator condenser heat dissipation structure includes a condenser pipe and an outer shell frame. A metal strip is fixedly connected to the outer wall of the condenser pipe. An air inlet is provided inside the outer shell frame. An air guide frame is fixedly connected to the upper surface of the outer shell frame. The air guide frame is conical in shape. A nylon wire is fixedly connected to the inner wall of the outer shell frame. A baffle is fixedly connected to the outer wall of the nylon wire. A fixing component is provided on the outer wall of the condenser pipe.

[0007] Through the above technical solution: the outer shell frame can enclose the condenser pipes and metal strips. When the condenser pipes are working, they heat the air inside the outer shell frame. The hot air rises naturally and is discharged from the interior of the outer shell frame through the air guide frame. The air guide frame is designed to be narrow at the top and wide at the bottom, which can enhance the flow rate and discharge capacity of the rising hot air. Then, cold air enters from the bottom of the outer shell frame through the air inlet to supplement the airflow and carry out a continuous air exchange process, improving air circulation efficiency. When the hot air rises, it can blow the baffles to continuously oscillate, creating disturbance and breaking the boundary layer air, further improving the air heat exchange efficiency. Through the passive heat rise channel with an open top and air intake at the bottom, and by blowing the baffles to break the air boundary and improve the air heat exchange efficiency, the natural heat dissipation capacity of the external grid condenser is greatly improved under zero power consumption conditions.

[0008] Preferably, the outer wall of the condenser pipe is fixedly connected to the outer wall of the refrigerator body, and the outer wall of the outer shell frame is fixedly connected to the outer wall of the refrigerator body.

[0009] Preferably, a motor is fixedly connected to the outer wall of the outer casing frame, and a sprocket is fixedly provided at the output end of the motor.

[0010] Preferably, the teeth of the sprocket are engaged with a chain, and a fixing block is fixedly connected to the outer wall of the chain.

[0011] Preferably, a sliding frame is slidably connected to the outer wall of the fixed block, and a brush plate is fixedly connected to the outer wall of the sliding frame.

[0012] Preferably, the inner wall of the brush plate is slidably connected to a slide rail, and the outer wall of the slide rail is fixedly connected to the inner wall of the outer frame.

[0013] Preferably, the outer wall of the brush plate is fixedly connected with brush bristles, and the outer wall of the brush bristles is disposed on the outer wall of the condensation pipe and the metal strip.

[0014] Preferably, a connecting post is rotatably connected inside the outer casing frame, one end of the connecting post is fixedly connected to a crank handle, and the other end of the connecting post is fixedly connected to the inside of the sprocket.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, through the cooperation between the condenser pipe, metal strip, outer frame, air inlet, air guide frame, nylon wire and baffle, a heat rise channel with an open top and air intake at the bottom is achieved. The baffle generates turbulent vortex, which further improves the air heat exchange efficiency, thereby significantly improving the natural heat dissipation capacity of the external grid condenser under zero power consumption conditions.

[0017] 2. In this utility model, the cooperation between the motor, sprocket, chain, fixing block, sliding frame, brush plate, slide rail and brush bristles prevents dust from covering the surface of the condensation pipe and metal strip, thus affecting the heat dissipation efficiency. It also eliminates the need for users to disassemble and clean regularly, improving maintenance convenience. Attached Figure Description

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. 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 protection scope of this utility model.

[0025] Example 1:

[0026] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a refrigerator condenser heat dissipation structure, including a condenser pipe 1 and an outer shell frame 3. A metal strip 2 is fixedly connected to the outer wall of the condenser pipe 1. An air inlet 4 is opened inside the outer shell frame 3. An air guide frame 5 is fixedly connected to the upper surface of the outer shell frame 3. The air guide frame 5 is conical in shape. A nylon wire 6 is fixedly connected to the inner wall of the outer shell frame 3. A baffle 7 is fixedly connected to the outer wall of the nylon wire 6. A fixing component is provided on the outer wall of the condenser pipe 1.

[0027] Specifically, the metal strip 2 provides structural support for the condenser pipe 1. The condenser pipe 1 and metal strip 2 form an external mesh condenser. When the condenser pipe 1 is operating, it dissipates a large amount of heat, heating the air inside the outer casing 3. As the air temperature rises, its density decreases, creating an upward airflow trend. This airflow is then discharged outside the outer casing 3 through the air guide frame 5. Because the air guide frame 5 has a narrower top and wider bottom shape, it enhances the upward flow velocity and discharge capacity of the hot air. As the hot air rises from the top, a slight negative pressure is created at the bottom, guiding cold air into the inner wall of the outer casing 3 through the air inlet 4, replenishing the airflow. A passive ventilation path with air entering from the bottom and exiting from the top is achieved. The outer frame 3 can provide fixed support for the nylon wire 6, which in turn can support multiple baffles 7. When air circulates, it blows the baffles 7, causing them to swing or flap, creating turbulent eddies in the air and further improving convective heat transfer efficiency. A continuous heat rise channel is established through the passive air guide path with an open top and air entering from the bottom. At the same time, baffles 7 driven by hot air are set in front of the condenser to break the air boundary layer and improve air heat transfer efficiency. Thus, the natural heat dissipation capacity of the external grid condenser is greatly improved under zero power consumption conditions.

[0028] Reference Figure 2 The outer wall of the condenser pipe 1 is fixedly connected to the outer wall of the refrigerator body 8, and the outer wall of the outer frame 3 is fixedly connected to the outer wall of the refrigerator body 8.

[0029] Specifically, the refrigerator body 8 can provide fixed support for the condenser pipe 1, and the refrigerator body 8 can also provide fixed support for the outer frame 3.

[0030] Reference Figure 3 A motor 9 is fixedly connected to the outer wall of the outer casing frame 3, and a sprocket 10 is fixedly installed at the output end of the motor 9; a chain 11 is meshed with the tooth end of the sprocket 10, and a fixing block 12 is fixedly connected to the outer wall of the chain 11; a sliding frame 13 is slidably connected to the outer wall of the fixing block 12, and a brush plate 14 is fixedly connected to the outer wall of the sliding frame 13.

[0031] Specifically, the outer frame 3 can provide fixed support for the motor 9. When the motor 9 is turned on, the motor 9 can drive the sprocket 10 to rotate. The rotation of the sprocket 10 will drive the chain 11 to slide back and forth. The sliding of the chain 11 will drive the fixing block 12 to slide back and forth. When the fixing block 12 slides vertically on the position of the chain 11, it will drive the sliding frame 13 to slide up and down. When the chain 11 on the left side of the fixing block 12 slides to the chain 11 on the right side, it will slide on the inner wall of the sliding frame 13, realizing the back and forth up and down sliding of the sliding frame 13.

[0032] Reference Figure 3The inner wall of the brush plate 14 is slidably connected to the slide rail 15, and the outer wall of the slide rail 15 is fixedly connected to the inner wall of the outer casing frame 3; the outer wall of the brush plate 14 is fixedly connected to the bristles 16, and the outer wall of the bristles 16 is set on the outer wall of the condensation pipe 1 and the metal strip 2.

[0033] Specifically, when the sliding frame 13 slides up and down, it will also drive the brush plate 14 to slide on the outer wall of the slide rail 15. The slide rail 15 can provide sliding support for the brush plate 14, ensuring the stability of the brush plate 14's sliding. The outer frame 3 can also provide fixed support for the slide rail 15. Furthermore, the up and down sliding of the brush plate 14 will also drive the bristles 16 to slide up and down. Through the up and down sliding of the bristles 16, they can contact the condenser pipe 1 and the metal strip 2, which can remove the dust on the surface of the condenser pipe 1 and the metal strip 2, preventing dust from covering the surface of the condenser pipe 1 and the metal strip 2 and affecting the heat dissipation efficiency. It also eliminates the need for users to disassemble and clean it regularly, improving maintenance convenience.

[0034] Example 2:

[0035] Reference Figure 4 The inner side of the outer frame 3 is rotatably connected to a connecting post 17. One end of the connecting post 17 is fixedly connected to a crank 18, and the other end of the connecting post 17 is fixedly connected to the inside of the sprocket 10.

[0036] Specifically, the outer frame 3 can provide rotational support for the connecting column 17, while the connecting column 17 can provide fixed support for the crank handle 18 and the sprocket 10. When facing the problem of reducing costs or power consumption, the crank handle 18 can be rotated to drive the connecting column 17 to rotate, and the rotation of the connecting column 17 will drive the sprocket 10 to rotate, replacing the motor 9 to drive the subsequent components to work and perform dust removal work on the condensation pipe 1.

[0037] Working principle: When the heat dissipation structure is needed, the condenser pipe 1 is opened. The condenser pipe 1 can heat the air inside the outer frame 3. The hot air passes through the narrow upper and wide lower structure of the air guide frame 5, which increases the flow rate and exhaust capacity of the hot air as it rises. At this time, the cold air enters the interior of the outer frame 3 through the air inlet 4, realizing a high heat exchange efficiency air circulation. When the air is circulating, it blows the baffle 7, causing it to swing or beat. The movement of the baffle 7 generates turbulent vortices in the air, further improving the convective heat exchange efficiency. Finally, a continuous heat rise channel is established through the passive air guide path with an open top and air intake at the bottom. At the same time, the baffle 7 driven by the hot air breaks the air boundary layer, further improving the air heat exchange efficiency. Thus, the natural heat dissipation capacity of the external grid condenser is greatly improved under zero power consumption conditions.

[0038] Then, the motor 9 is turned on, which drives the sprocket 10 to rotate. The rotation of the sprocket 10 drives the chain 11 to slide back and forth, and the back and forth sliding of the chain 11 also drives the fixed block 12 to slide back and forth. At the same time, the sliding of the fixed block 12 drives the sliding frame 13 to slide up and down back and forth. The up and down sliding of the sliding frame 13 also drives the outer wall of the slide rail 15 of the brush plate 14 to slide back and forth, thereby driving the bristles 16 to brush the surface of the condenser pipe 1 and the metal strip 2 back and forth, removing dust from the condenser pipe 1 and the metal strip 2, preventing dust from covering the surface of the condenser pipe 1 and the metal strip 2 and affecting the heat dissipation efficiency. It also eliminates the need for users to disassemble and clean regularly, improving maintenance convenience. Similarly, by turning the crank 18, the connecting column 17 is driven to rotate, and the rotation of the connecting column 17 drives the sprocket 10 to rotate, thereby driving the subsequent components to remove dust from the condenser pipe 1.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
