Description

Technical Field

[0001] This utility model relates to the field of condensation technology, specifically to a high-efficiency, energy-saving, and intelligent condensing unit. Background Technology

[0002] As is well known, in the existing industrial refrigeration and air conditioning field, condensing units are key heat exchange equipment, and their energy efficiency level directly affects the overall energy consumption of the system. Traditional condensing units generally have many technical bottlenecks in use.

[0003] Specifically, when existing condensing units are in use, the surface of the heat sink is exposed to the external environment for a long time, which easily attracts dust, oil and biological adhering substances, leading to an increase in thermal resistance. This forces the compressor to run at high frequency to maintain the cooling capacity, resulting in wasted energy. Regular cleaning requires manual brushing or high-pressure water gun rinsing after the machine is shut down, which is not only dangerous to operate, but also limits the cleaning frequency and makes it impossible to achieve real-time optimization of the surface condition of the heat sink. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a high-efficiency, energy-saving, and intelligent condensing unit.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency energy-saving intelligent condensing unit, including a shell, a cavity inside the shell, a wind-facing grille at the front end of the cavity, a condensing tube with heat sink fins inside the cavity, a cleaning device at the front end of the heat sink fins, and an auxiliary spraying device at the upper end of the cleaning device.

[0008] To achieve precise, comprehensive cleaning of the heat sink surface using the cleaning device, this invention includes the following improvements: The cleaning device comprises a moving rod, a sliding rod, a connecting block, and a cleaning block. The moving rod and the sliding rod are symmetrically arranged at both ends of the front side of the heat sink. The connecting block connects the moving rod and the sliding rod. A control motor is provided at one end of the upper sidewall of the housing. The moving rod passes through the upper sidewall of the housing and is connected to the output end of the control motor. Multiple cleaning blocks are arranged in groups at the front end of the connecting block, and the cleaning blocks are adapted to the heat sink.

[0009] To achieve directional spraying, the present invention is improved as follows: the auxiliary spraying device includes a water pump, a connecting pipe, a water storage tank, and a water outlet pipe. The water outlet pipes are arranged in multiple groups on the bottom wall of the water storage tank. The output end of the water pump passes through the upper side wall of the water storage tank. The connecting pipe is connected to the input end of the water pump. The water outlet pipe passes through the upper side wall of the outer casing and is adapted to the heat sink.

[0010] In order to effectively collect the wastewater generated during the cleaning process, the present invention is improved as follows: a wastewater box is provided on the bottom wall of the cavity, the wastewater box passes through the outer shell and is slidably connected to it, and a pull block is provided at one end of the wastewater box.

[0011] To significantly improve cleaning reliability, the present invention includes the following improvements: both the connecting block and the cleaning block are covered with wear-resistant nylon bristles.

[0012] To enhance thermal conductivity, the present invention includes the following improvement: the surface of the heat sink is coated with a titanium dioxide-graphene composite coating.

[0013] To match the optimal airflow and avoid energy waste, the present invention is improved by providing a dual axial flow fan assembly inside the windward grille, and the fan speed can be steplessly adjusted by a frequency converter.

[0014] To significantly reduce fan operating noise and improve user experience, the present invention includes the following improvement: the blade surface of the dual axial flow fan assembly is coated with a graphene-polyurethane noise reduction coating.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a high-efficiency, energy-saving, and intelligent condensing unit, which has the following beneficial effects:

[0017] This high-efficiency, energy-saving, and intelligent condensing unit is equipped with an air intake grille and a built-in dual axial flow fan assembly with stepless speed regulation via a frequency converter. It can adjust the fan speed in real time according to the ambient temperature and the heat load of the heat sink, avoiding the "overcooling" or "undercooling" phenomenon caused by traditional fixed fan speeds. This ensures that the condenser tubes are always in the optimal heat exchange state, significantly reducing the compressor start-stop frequency and overall energy consumption.

[0018] Equipped with a cleaning device, the moving rod and cleaning block can move precisely back and forth along the surface of the heat sink. Combined with the directional spraying of multiple water outlet pipes, it realizes the "dry sweeping-wet washing" staged operation. After the cleaning block physically scrapes away large particles of dirt, the water mist spray softens the residual oil and washes it at the same time, avoiding secondary pollution or cleaning dead corners caused by a single cleaning method, and extending the efficient operation cycle of the heat sink.

[0019] The operating pressure, spray water pressure and fan speed of the cleaning device form a closed-loop control, automatically matching the cleaning intensity according to the degree of contamination of the heat sink, preventing equipment damage caused by over-cleaning and reducing the frequency of manual maintenance.

[0028] Please see Figure 1-4A high-efficiency, energy-saving, intelligent condensing unit includes a housing 1, with a cavity inside the housing 1. A windward grille 6 is provided at the front end of the cavity. A condenser tube with heat sink 13 is installed inside the cavity. A cleaning device is provided at the front end of the heat sink 13. An auxiliary spraying device is provided at the upper end of the cleaning device. The auxiliary spraying device includes a water pump 4, a connecting pipe 5, a water storage tank 3, and a water outlet pipe 12. Multiple sets of water outlet pipes 12 are arranged on the bottom wall of the water storage tank 3. The output end of the water pump 4 passes through the upper side wall of the water storage tank 3. The connecting pipe 5 is connected to the input end of the water pump 4. The water outlet pipe 12 passes through the upper side wall of the housing 1 and is adapted to the heat sink 13. A wastewater box 7 is provided on the bottom wall of the cavity. The wastewater box 7 passes through the housing 1 and is slidably connected to it with damping. A pulling block 8 is provided at one end of the wastewater box 7. A dual-axial flow fan group is provided inside the windward grille 6, and the fan speed can be steplessly adjusted by a frequency converter.

[0029] During operation, when the unit starts, the refrigerant in the condenser absorbs heat and enters a gaseous state. It then flows through the condenser with densely packed heat sinks 13. At this time, the dual-axial flow fan assembly inside the air intake grille 6 is started by the frequency converter, dynamically adjusting the fan speed according to the temperature difference. For example, under high-temperature conditions, the speed is automatically increased (e.g., above 40Hz) to increase airflow and accelerate heat dissipation; under low-temperature or low-load conditions, the speed is reduced (e.g., below 20Hz) to avoid energy loss due to excessive heat dissipation. The airflow generated by the fan assembly, after being guided by the air intake grille 6, forms a laminar flow curtain perpendicular to the surface of the heat sinks 13. When the airflow penetrates the gaps in the heat sinks 13, it quickly carries the heat released by the condenser out of the cavity, while reducing energy loss caused by airflow bypass. The heat sinks 13, by increasing the contact area with the air, efficiently transfer the refrigerant heat to the flowing air, completing the refrigerant liquefaction process. The liquid refrigerant then flows back to the internal compressor for circulation (this process is a mature technology and will not be elaborated upon here). When contaminants accumulate on the surface of the heat sinks 13, causing an increase in thermal resistance... When the preset cleaning cycle is reached, the system automatically switches to cleaning mode. First, it pauses the operation of the dual axial flow fan and closes the refrigerant circulation valve on the condenser tube to ensure the safety of the cleaning operation. The connecting pipe 5 is connected to an external clean water source (such as filtered water or circulating water). After the water pump 4 starts, water is injected into the water storage tank 3. Multiple sets of water outlet pipes 12 at the bottom of the water storage tank 3 evenly spray water mist onto the surface of the heat sink 13, softening dust, oil and other contaminants adhering to the gaps between the heat sink 13. The amount of water sprayed is precisely controlled by the water pump 4 to prevent water from splashing into non-clean areas. Simultaneously, the cleaning device is activated, scraping the surface of the heat sink 13. During the cleaning process, the water pump 4 continuously supplies water, and the jet of water from the water outlet pipe 12 washes away the residual dirt from the surface of the heat sink 13, forming a dynamic cleaning effect of "sweeping and rinsing at the same time" to prevent dirt from adhering to the surface again. The wastewater generated during cleaning flows into the wastewater box 7 along the inclined guide channel at the bottom of the cavity. The user can pull the wastewater box 7 outward by pulling the block 8 (the damping sliding design ensures a smooth pulling process) and pour or wash it directly. After completion, push the box back into the box. No tools are required to disassemble the entire process.

[0030] In practical use, it is necessary to achieve precise, comprehensive cleaning of the heat sink 13 surface using the cleaning device to ensure efficient removal of contaminants from the gaps between the heat sink 13 and maintain optimal heat dissipation efficiency. To meet the above requirements, in this embodiment, the cleaning device includes a moving rod 9, a sliding rod 10, a connecting block 11, and cleaning blocks 14. The moving rod 9 and the sliding rod 10 are symmetrically arranged at both ends of the front side of the heat sink 13. The connecting block 11 connects the moving rod 9 and the sliding rod 10. A control motor 2 is provided at one end of the upper sidewall of the outer casing 1. The moving rod 9 passes through the upper sidewall of the outer casing 1 and is connected to the output end of the control motor 2. Multiple sets of cleaning blocks 14 are arranged at the front end of the connecting block 11. The cleaning blocks 14 are adapted to the heat sink 13.

[0031] The control motor 2 starts and drives the moving rod 9 to rotate. Under the limit of the sliding rod 10, the connecting block 11 rises and falls with the rotation of the moving rod 9, thereby causing multiple sets of cleaning blocks 14 (with staggered arrangement design) to rise and fall, and to clean the heat sink 13 in close contact, ensuring that there are no dead corners in cleaning the heat sink 13.

[0032] In actual use, it is necessary to improve cleaning reliability. In order to meet the above requirements, in this embodiment, the surfaces of the connecting block 11 and the cleaning block 14 are both covered with wear-resistant nylon bristles.

[0033] In practical use, it is necessary to enhance the thermal conductivity and achieve the dual advantages of self-cleaning and high thermal efficiency of the heat sink 13. In order to meet the above requirements, in this embodiment, the surface of the heat sink 13 is coated with a titanium dioxide-graphene composite coating.

[0034] In practical use, it is necessary to significantly reduce fan operating noise and improve user experience. In order to meet the above requirements, in this embodiment, the blade surface of the dual axial flow fan group is coated with a graphene-polyurethane noise reduction coating.
