Heat Exchanger Design for Enhanced Performance

Heat exchange device for air conditioning that enhances performance by using a novel configuration of heat pipes and fins. The device incorporates a shell that stores air, a surface cooler with thermally connected heat exchange fins, and a separate group of heat exchange fins positioned upstream and downstream of the cooler. The heat pipes connect the cooler's heat exchange fins to the upstream heat exchange fins, enabling efficient heat transfer through both the cooler and the fins. This configuration addresses the issue of excessive temperature differences between the heat medium and low-temperature air in extreme cold environments, while maintaining high air flow rates and system efficiency.

Microchannel heat exchanger design with compact layout and reduced refrigerant charge for air conditioners. The heat exchanger has multiple features that improve efficiency, reduce size, and lower refrigerant charge compared to conventional designs: 1. Dense protrusions on the channels with higher density compared to the connecting portion. This increases heat transfer while maintaining the same overall channel length. 2. The channels are arranged in a body with openings at the ends. This allows a single body to be bent and joined without gaps, reducing the overall size compared to conventional designs with gaps between cores. 3. The inlet and outlet tubes have smaller diameters compared to the headers. This reduces the inner volume of the headers and lowers refrigerant charge. 4. The heat exchanger is used in an air conditioner.
