AI Technical Summary
Traditional liquid chillers lack a precise airflow guiding structure, which can easily cause turbulence or dead zones in the cavity. Some of the cold air does not effectively reach the high heat flux density area, requiring the compressor to run at a high load continuously, thus increasing energy consumption.
The cold air guiding mechanism, which uses components such as guide tubes, guide frames, guide blocks, and limit blocks, ensures that cold air is accurately delivered to key heat dissipation areas and effectively discharges condensed water droplets through precise air guiding and water droplet management.
It improves the cooling and operating efficiency of the liquid chiller, prevents turbulence and water droplets, and reduces energy consumption.

[0001] This utility model relates to the technical field of liquid chillers, specifically to a cold air guiding mechanism for an AC / DC integrated liquid chiller. Background Technology
[0002] The cold air guide mechanism is a key component used in AC / DC integrated liquid chillers to optimize airflow paths and improve heat dissipation efficiency. Its core function is to accurately and evenly deliver the cold air generated by the compressor to the key heat dissipation areas of the liquid chiller, thereby ensuring efficient cooling and reducing energy consumption.
[0003] In traditional liquid cooling systems, the flow of cold air mainly relies on simple airflow or non-directional air delivery.

[0019] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0020] like Figures 1-3As shown, a cold air guiding mechanism for an AC / DC integrated liquid chiller includes a guide pipe 1, which is fixed to a guide frame 2. One end of the guide pipe 1 extends into the guide frame 2. A guide block 3 is fixed to the bottom surface of the guide frame 2. An arc surface 4 is formed on the guide block 3. Limiting blocks 5 are fixed on both sides of the inner wall of the guide frame 2. The bottom surface of the limiting block 5 is fixed to the top surface of the guide block 3. A clamp 6 is snapped onto the outer wall of the guide pipe 1. The length of the guide frame 2 is 1m. A water collection trough 7 is formed on the bottom surface of the guide frame 2. A connecting pipe 8 is passed through the bottom surface of the guide frame 2 and extends into the water collection trough 7. A drain pipe 9 is passed through the outer wall of the guide pipe 1. The top end of the drain pipe 9 extends into the guide pipe 1. The other end of the connecting pipe 8 extends into the drain pipe 9. The inner wall of the water collection trough 7 and the inner wall of the guide frame 2 are both inclined surfaces, and the two inclined surfaces are connected to each other.
[0021] During operation, the flow guide pipe 1, flow guide frame 2, flow guide block 3, and limiting block 5 work together to guide the cold air generated by the liquid chiller compressor, ensuring accurate delivery of the cold air to the fan module and guaranteeing the cooling efficiency of the liquid chiller. This effectively prevents turbulence during the flow guidance process, thus improving the performance of the liquid chiller. The connecting pipe 8 guides and discharges condensed water droplets, effectively preventing backflow caused by prolonged accumulation of water droplets in the flow guide pipe 1, thereby ensuring the working efficiency of the liquid chiller.
[0022] like Figures 1-3 As shown, a flow channel 10 is provided on the limiting block 5, which corresponds to the arc surface 4. Flow channels 11 are provided on both the left and right sides of the inner wall of the flow guide frame 2. The flow channels 11 are connected to the water collection tank 7. A folding plate 12 is fixed on the inner top surface of the flow guide frame 2. The two limiting blocks 5 are fixed to the left and right sides of the folding plate 12 respectively.
[0023] During use, the interaction between the drainage channel 10 and the guide channel 11 limits and guides the condensed water droplets, allowing them to flow smoothly into the collection tank 7. This effectively prevents the water droplets from being blown outdoors with the cold air, thereby improving the cooling efficiency of the liquid chiller. The baffle plate 12 blocks the condensed water droplets, allowing them to gather within it and flow into the drainage channel 10, effectively preventing dripping.
