To provide a vehicle interior temperature lowering device capable of efficiently lowering a vehicle interior temperature by increasing temperature gradient between both end portions of an indoor side heat pipe by positively radiating heat at a fastening portion of the indoor-side heat pipe and an outdoor-side heat pipe.
This vehicle interior temperature lowering device comprises the indoor-side heat pipe 12 thermally connected with a heat absorbing plate 11 mounted in a cabin R, the outdoor-side heat pipe 14 thermally connected with an underfloor radiator 13 mounted at a lower side of a car body floor, and a fastening connector 15 for thermally connecting the indoor-side heat pipe 12 and the outdoor-side heat pipe 14 at the outside of the cabin, and the fastening connector 15 is provided with the heat radiating means 20, thus temperature gradients respectively between the heat absorbing plate 11 and the fastening connector 15 and between the fastening connector 15 and the underfloor radiator 13 can be increased, the temperature of the device as a whole can be significantly lowered, and the vehicle interior temperature can be efficiently lowered.
