Abstract
An air cooled resistor arrangement comprising a first elongated tube member forming a first air flow channel and a second elongated tube member forming a second air flow channel, wherein the first elongated tube member is at least partly housed inside the second elongated tube member. The air-cooled resistor arrangement further comprises an air dilution portion comprising at least one opening at which the first air flow channel is arranged in fluid communication with the second air flow channel.
Claims15
An air-cooled resistor arrangement, comprising:
- an inlet configured to receive a flow of air, and an outlet configured to convey the flow of air out from the resistor arrangement,
- a first elongated tube member forming a first air flow channel configured to convey a first air flow portion from the inlet towards the outlet, the first elongated tube member extending between the inlet and the outlet,
- a second elongated tube member extending between the inlet and the outlet, wherein the first elongated tube member is at least partly housed by the second elongated tube member, the first and the second elongated tube members being spaced apart from each other to form a second air flow channel configured to convey a second air flow portion from the inlet, and
- an electrically conductive resistor element comprising an electric resistive material connectable to a source of electric power, the resistor element being arranged inside the first elongated tube member,
- wherein the air-cooled resistor arrangement further comprises an air dilution portion comprising at least one opening at which the first air flow channel is arranged in fluid communication with the second air flow channel, the air dilution portion being arranged at a position between the inlet and the outlet.
