Heat pump unit for transferring heat using magnetic particle dispersion
The patent application (Publication Number: US20240035715A1) describes a heat pump unit designed to transfer heat between external heat-giving and heat-receiving fluids using a magnetic particle dispersion as the primary working fluid. The unit includes an internal heat-absorbing section, an internal heat-releasing section, an external heat-absorbing section, an external heat-releasing section, and a circulation channel for the secondary working fluid. The primary working fluid circulates between the internal sections of the heat pump, while the secondary working fluid moves between the external sections and the heat pump, facilitating the transfer of heat between the two fluids.
Furthermore, the patent application details the arrangement of the heat pump in multiple stages along the flow direction of the secondary working fluid in the circulation channel. Each stage of the heat pump includes a magnetic material selected based on the temperatures of heat absorption and release in the internal sections. The source of the magnetic field in the unit is a permanent magnet, and the secondary working fluid flows through a common channel with the primary working fluid for heat exchange, with one fluid being hydrophilic and the other hydrophobic. These innovative features aim to enhance the efficiency and effectiveness of heat transfer in the heat pump unit, offering potential benefits in various applications requiring heat exchange processes.
