[0002] An integrated chiller is a modular chiller that integrates the evaporator, condenser, heat dissipation components, refrigeration components, and circulation components into a single unit. It is widely used in constant temperature and humidity environments such as cabinet-type and box-type storage systems, and room ventilation systems. Traditional integrated chillers mostly have a simple structure for their heat exchange and circulation air supply units, which can only deliver air to a designated outlet and cannot be adapted to different usage scenarios. The heat exchange and circulation air supply units need to be redesigned according to the requirements of each scenario. This limits the ease of use of integrated chillers. Therefore, further improvements are needed. Utility Model Content

[0022] Example Reference Figures 1 to 5 The present invention proposes an integrated refrigeration unit with a vertical air inlet and outlet structure, comprising: a housing 10 and a compressor 20, an evaporator assembly 30, a condenser assembly 40, a cooling fan 50, a refrigeration circulation fan 60, and a refrigeration circulation cover 70 disposed within the housing 10. The compressor 20, evaporator assembly 30, and condenser assembly 40 are connected by pipes; the refrigeration cycle cover 70 is disposed inside the housing 10, dividing the space of the housing 10 into a refrigeration chamber inside the refrigeration cycle cover 70 and a heat dissipation chamber outside the refrigeration cycle cover 70; the compressor 20, evaporator assembly 30, and cooling fan 50 are disposed in the heat dissipation chamber. The refrigeration circulation shroud 70 is surrounded by a refrigeration air inlet channel 71 and a refrigeration air outlet channel 72; the refrigeration circulation fan 60 is used to generate a refrigeration airflow from the refrigeration air inlet channel 71 toward the refrigeration air outlet channel 72; the condenser assembly 40 is arranged close to the refrigeration circulation fan 60; the refrigeration air outlet channel 72 is a channel structure formed vertically to the refrigeration circulation shroud 70, and refrigeration air outlets are provided at both the upper and lower ends of the refrigeration circulation shroud 70.

[0023] This invention innovatively constructs a vertical air outlet structure by setting cooling air outlets at both the upper and lower ends of the cooling circulation hood 70. This design breaks the limitation of traditional single-direction air supply, allowing the refrigeration unit to flexibly achieve upward or downward air supply modes by simply selecting to open the upper or lower air outlet without internal structural adjustments. This adapts to diverse installation and application scenarios such as top-down and bottom-up air supply. When facing the differentiated needs of different customers, there is no need to redesign and customize dedicated heat exchange circulation air supply units for specific air supply directions, simplifying the selection, procurement, and inventory management process, reducing overall operating costs, and enhancing market competitiveness. The compact vertical channel structure is closely integrated with the internal space of the cooling circulation hood 70, helping to reduce duct bends and form a smooth cooling airflow path. This reduces airflow resistance and energy loss to a certain extent, improves the efficiency of the cooling cycle, and makes the overall structure more rational.

[0024] In this embodiment, the cooling air inlet channel 71 is a channel structure formed vertically within the cooling circulation shroud 70, with cooling air inlets at both the upper and lower ends of the cooling circulation shroud 70. By also setting the cooling air inlet channel 71 as a vertical structure and opening air inlets at both the upper and lower ends, bidirectional reversibility of the air inlet and outlet directions is achieved. This not only further enhances the equipment's adaptability to different installation environments (e.g., enabling multiple circulation modes such as "bottom inlet, top outlet" or "top inlet, bottom outlet"), but also reduces airflow resistance by forming a smooth vertical airflow channel, thereby reducing fan energy consumption and operating noise, and achieving efficient, low-noise, and stable operation.

[0025] In this embodiment, the refrigeration circulation hood 70 is also provided with a connecting ventilation duct 73, which connects the refrigeration air inlet channel 71 and the refrigeration air outlet channel 72; the condenser assembly 40 and the refrigeration circulation fan 60 are disposed in the connecting ventilation duct 73. The connecting ventilation duct 73 cleverly connects the vertical inlet and outlet channels, forming a complete and compact "U-shaped" or "Z-shaped" airflow path. This ensures that the airflow is smooth and concentrated throughout the entire process from intake to heat exchange in the condenser and then to exhaust, minimizing eddies and pressure losses, making the airflow system more efficient and rational, the overall structure more compact, and saving internal space.

[0026] Specifically, the connecting ventilation duct 73 is arranged horizontally; the condenser assembly 40 is located at the end of the connecting ventilation duct 73 near the refrigeration air inlet channel 71; and the refrigeration circulating fan 60 is located at the end of the connecting ventilation duct 73 near the refrigeration air outlet channel 72. The airflow first flows through the condenser for effective heat exchange, and then is forced out by the fan, forming an airflow sequence that best conforms to thermodynamic principles. This arrangement avoids airflow short-circuiting, ensuring that all air flowing through the condenser is fully utilized, thereby maximizing heat exchange efficiency and helping to reduce the fan load, achieving energy-saving operation.

[0027] In this embodiment, a condenser water pan 41 is disposed below the refrigeration chamber, and an evaporator water pan 31 is disposed below the heat dissipation chamber. Water in the condenser water pan 41 can flow to the evaporator water pan 31. A high-temperature and high-pressure pipeline 21 is disposed between the compressor 20 and the evaporator assembly 30. At least a portion of the high-temperature and high-pressure pipeline 21 is arranged within the evaporator water pan 31. The waste heat of the high-temperature and high-pressure pipeline 21 between the compressor 20 and the evaporator assembly 30 is used to evaporate the condensate produced by the condenser and evaporator. This achieves fully self-evaporation without a pump or external drain pipe, eliminating the hassle of manual drainage for users and avoiding the limitations of installing drain pipes, thus broadening the product's application scenarios. At the same time, it achieves energy recycling, making it more energy-efficient and environmentally friendly. The high-temperature pipeline heats the condensate in the evaporator water pan 31, which is equivalent to providing a preliminary subcooling for the liquid refrigerant, helping to improve the efficiency of the evaporator, thereby bringing a slight improvement in the overall energy efficiency of the system.

[0028] In this embodiment, the evaporator water pan 31 is equipped with a water suction component 32, which is arranged close to the cooling fan 50. Capillary action is used to continuously and evenly transport the condensate in the evaporator water pan 31 to its surface, greatly increasing the contact area between water and air. When the airflow from the cooling fan 50 passes through, it greatly accelerates the evaporation rate of the water, ensuring that water is evaporated promptly even under high water load, preventing water pan overflow, and improving the system's reliability and self-evaporation efficiency.

[0029] Preferably, the absorbent component 32 is made of cotton pulp absorbent corrugated paper. The cotton pulp absorbent corrugated paper material is easy to replace and simple to maintain, achieving a comprehensive benefit of high efficiency, low cost and maintenance-free operation.

[0030] In this embodiment, the housing 10 is provided with a heat dissipation vent 11; the exhaust end of the cooling fan 50 is arranged near the heat dissipation vent 11; and the water absorption assembly 32 is arranged near the air inlet end of the cooling fan 50. This arrangement precisely positions the water absorption assembly 32 at the air inlet end of the cooling fan 50, i.e., the area in the heat dissipation chamber with the greatest negative pressure and the fastest airflow. This maximizes the utilization of the heat dissipation airflow, removing moisture from the surface of the water absorption assembly 32 with the highest efficiency, ensuring optimal condensate evaporation.

[0031] In this embodiment, the evaporator water pan 31 is equipped with a water level detection unit 80; the housing 10 has a water inlet located above the evaporator water pan 31. The water level detection unit 80 allows for real-time monitoring of the water level in the evaporator water pan 31. When the water level becomes abnormally high or low, an alarm can be triggered or the operating power of the compressor 20 and cooling fan 50 can be automatically controlled to prevent water overflow or to prompt the user to add water, thus improving the intelligence, safety, and operational reliability of the equipment.

[0032] In this embodiment, the height of the evaporator water pan 31 is lower than that of the condenser water pan 41; the condenser water pan 41 directs water to the evaporator water pan 31 through the drainage channel 90.

[0033] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
