Abstract:
A heat-exchanging device being attached to a box to form an approximately sealed inner space within the box, said heat-exchanging device comprising:a heat exchanger having therein a plurality of inside air passages extending substantially in a vertical direction through which inside air inside the box flows, and a plurality of outside air passages extending substantially in the vertical direction through which outside air outside the box flows, said inside air passages and said outside air passages are alternately adjacently arranged; and a casing for accommodating said heat exchanger, said casing having an outer wall surface in which an outside air introduction port for introducing outside air into said outside air passages and an outside air discharging port for discharging outside air from said outside air passage are provided, wherein: said heat exchanger is disposed in said casing to form a space having a predetermined distance greater than zero between the heat exchanger and said outer wall surface, said space extending substantially in the vertical direction along approximately an entire length of said heat exchanger in the vertical direction; said outside air passages are provided to communicate with said outside air discharge port through said space; said heat exchanger has a plate member defining said inside air passages of said heat exchanger: said plate member of said heat exchanger is disposed to be fastened to an attachment wall surface of said casing by using a fastening member at a position defining said inside air passages; and the fastening member includes a flat plate contacting a surface of the plate member in said inside air passage, a seal nut disposed on said outer wall surface of said casing at a side opposite to the flat plate, and a screw that is fastened into the seal nut from the flat plate through a through hole of the flat plate and a through hole of said outer wall surface.
