<P>PROBLEM TO BE SOLVED: To meet the need for temporarily heating the inner space of a box-like structure for actuating an equipment in the box-like structure in the case where the inner space of the box-like structure is cooled due to a low outdoor air temperature, and solve the problem that there is the anxiety that dusts, water contents and the like are invaded into the box-like structure by directly introducing outdoor air into the outdoor air so that the equipment housed therein would be affected adversely. <P>SOLUTION: A heat exchange type cooler comprising an internal air path 5 for taking air in the box-like structure (hereinafter referred to as "internal air") and returning the air thereinto for circulation of air, an air blower 2 which has external air paths 8 for taking air outside the box-like structure (hereinafter referred to as "external air") and discharging the air out of the box-like structure arranged mutually independent, and carries the air in the external air path 8 and internal air path 5, a heat exchanging element 3 which is arranged at a cross point between the external air path 8 and internal air path 5 to exchange sensible heat of the external air and internal air, and a heating means 9 arranged to be in contact with the internal air path 5, wherein the heat exchange type cooler enables the operation of the cooling method by heat exchange between the external air and internal air and the heating method by the heating means 9, alone or in combination. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
