To provide a radiation system capable of reducing the number of opening portions in penetrating a heat transporting portion through a dash panel.
One end portion of a heat pipe 11 as the heat transporting portion is disposed at a heat source side, a radiating portion 12 connected with the other end portion of the heat pipe 11 is disposed in a cowl top 2, and the heat pipe 11 is inserted into a communicating port 4 of the dash panel connected with an air introduction duct 21 of an air conditioning unit 20, thus the number of opening portions formed on the dash panel 1 can be reduced, a structure of the dash panel 1 can be simplified, and degradation of rigidity of the dash panel 1 is prevented to prevent degradation of sound vibration performance.
