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.
