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.

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.

Abstract: A cooling member includes a heat-transfer member, a refrigerant introducing pipe and a covering material. The heat-transfer member has a surface with a groove opened to the surface of the heat-transfer member. The refrigerant introducing pipe is pressed into the groove. The covering material coats the surface of the heat-transfer member and the refrigerant introducing pipe.

Abstract: A refrigerant pipe attachment structure is provided, in which it can be ensured that a refrigerant pipe is held and thermal resistance between the refrigerant pipe and a heat transfer member can be sufficiently reduced. A heat transfer member formed with an elongated groove into which a refrigerant pipe is fitted and thermally contacting a cooling target is provided. An elastic member formed in an elongated plate shape extending along an extension direction of the refrigerant pipe and including a pipe-facing part facing the refrigerant pipe is provided. A pressing mechanism configured to press the elastic member toward the heat transfer member is provided.
