  As is well known, the heat exchanger 9 is not labeled in the drawing, but on the surface of the first plate, on the surface of the second plate, on the surface of the second plate. The three plate bodies are polymerized in a state of being separated from each other by a predetermined interval to form a substantially rectangular parallelepiped, and the surface of the first plate body is a lane on the surface of the first plate body on the second plate body side. A plurality of first rectifying walls that are partitioned into a plurality of shapes, and a plurality of second rectifying walls that divide the surface of the second plate into lanes are provided on the surface of the second plate on the side of the third plate. In this configuration, the first air passage 10 and the second air passage 11 intersect each other at a right angle with the second plate member interposed therebetween. Further, these first to third plate bodies are obtained by laminating a large number as a number obtained by adding one to the number of air paths intersected in the heat exchanger 9.

  The heat exchanging device 1 is installed at the upper part inside the box-shaped cabinet 12 that divides the space for storing the transmitter / receiver of the mobile phone that is the second environment with respect to the outside air that is the first environment. .

The cabinet 12 has a double wall surface , the outer first wall plate 25 is provided with a first opening 14 communicating with the first environment, and the inner first wall plate 26 is provided with a first opening 14.
