PURPOSE:To improve rapid room heating performance, when an engine performs its cold starting, by transporting quantity of heat in an exhaust system to be fed to an air conditioning system utilizing magnetic fluid while absorbing heat to the magnetic fluid through a heat exchange in an exhaust manifold with cooling water of the engine. CONSTITUTION:Providing an introducing port 11 of magnetic fluid, opened to a cooling water jacket 6, and a separator 12, separating engine cooling water passing through in the cooling water jacket 6 from the magnetic fluid, to be respectively arranged in an exhaust manifold 2 of an engine main unit 1, thus a heat absorbing heat exchanger means 13, performing a heat exchange between the engine cooling water and the magnetic fluid, is constituted. The separator 12 provides each coil 15, 17 generating a magnetic field respectively moving the magnetic fluid. While in a conditioned air route 4, a heat exchanger 18 of its inside air with the magnetic fluid is provided. Further along a magnetic fluid circulative route 16, a suitable number of coils 2, generating in its inside the magnetic field, are provided to be arranged. |
