  • Patent number: 12000628
    Abstract: A magnetic refrigeration module includes a housing, low and high temperature inflow paths, low and high temperature outflow paths, and first and second intermediate flow paths. The housing houses a magnetic working substance, and forms a flow path. The low and high temperature inflow paths carry heating medium into first and second ends of the flow path. First and second spaces are formed between the first and second ends and the low and high temperature inflow paths. The low and high temperature outflow paths receive the heating medium from the first and second ends of the flow path. The first and second intermediate flow paths communicate with the low and high temperature inflow paths and the first and second spaces. The first and second intermediate flow paths expand heating medium flow from the low and high temperature inflow paths to the first and second spaces.

  • Publication number: 20220412610
    Abstract: A cooling module for solid-state refrigerant cooling includes an annular storing portion having a housing portion, low and high temperature side inflow paths, low and high temperature side outflow paths, first and second spaces between the first and second ends of housing flow paths and the low and high temperature side inflow paths, and first and second intermediate flow paths. The first intermediate flow path is in fluid communication with the low temperature side inflow path and the first space, and is configured to widen a flow of the heating medium flowing from the low temperature side inflow path to the first space. The second intermediate flow path is in fluid communication with the high temperature side inflow path and the second space, and is configured to widen a flow of the heating medium flowing from the high temperature side inflow path to the second space.

  • Publication number: 20220186991
    Abstract: A solid-state refrigeration apparatus includes a solid cooling structure, first and second heat exchangers, a heating medium circuit, a reciprocating conveying mechanism, and a thermal storage section. The solid cooling portion includes a solid refrigerant substance, an internal channel where the solid refrigerant substance is disposed, and an induction section configured to cause the solid refrigerant substance to produce a caloric effect. The heating medium circuit is connected to the first and second heat exchangers, and the internal channel. The heating medium heated by the solid cooling portion dissipates heat in the first heat exchanger and the heating medium cooled by the solid cooling portion absorbs heat in the second heat exchanger a heat application operation. Frost on the second heat exchanger is melted using the heat stored in the thermal storage section in a defrosting operation. The thermal storage section stores heat in the heat application operation.
