Latest Patents

One of his latest patents is a defrost system that utilizes an electric heater for thermosiphon. This system includes a thermosiphon defrost circuit branched from a circulation line. During defrosting, a CO refrigerant within a fin-tube heat exchanger undergoes a two-phase change, creating a CO circulation path. The system features electromagnetic opening and closing valves that maintain a closed circuit during defrosting. Additionally, a first electric heater is strategically placed above the thermosiphon defrost circuit to facilitate natural circulation of the CO refrigerant.

Another significant patent is related to a plate stack and heat exchanger. This invention consists of multiple plates with corrugated portions on both surfaces. The design includes first and second heat exchange flow passages formed between the plates, which are arranged alternately. Each plate has two through holes for introducing and deriving the first heat exchange fluid. The plate stack also incorporates first partition weirs that are symmetrically and obliquely arranged, enhancing the efficiency of the heat exchange process.
