OUTER PANEL COOLING SYSTEM

An outer panel-mediated cooling system includes: an outer shell including an outer panel and an inner panel; a heat source chamber located inward of the inner panel; a cooling path that is located between the outer and inner panels, into which at least one of a pressurized gas and a return gas from the heat source chamber flows, in which the at least one gas releases heat outside through the outer panel to change into a cooled gas, and out of which the cooled gas flows; a non-cooling path that is located between the outer and inner panels and thermally insulated from the cooling path and the outer panel and through which at least one of the pressurized gas and the return gas from the heat source chamber passes; a mixing chamber into which the cooled gas leaving the cooling path and an uncooled gas leaving the non-cooling path flow, in which the cooled gas and the uncooled gas are mixed to form a mixed gas, and out of which the mixed gas flows toward the heat source chamber; and a flow rate regulating valve that regulates a flow rate of the cooled gas flowing toward the mixing chamber.
