To provide a heat radiation structure of a vehicle which can release heat of an exhaust section to an upper side of an engine room with a simple structure.SOLUTION: A heat radiation structure 1 of a vehicle includes: an exhaust section 2 of an internal combustion engine 10; a water-cooling intercooler 4; a heat-shielding member 6; and a fluid filling port 8. The water-cooling intercooler 4 is arranged on an upper side in a vertical direction G of the vehicle of the exhaust section 2. The heat-shielding member 6 covers the exhaust section 2 from a longitudinal direction Q and a vehicle width direction P of the vehicle C, heat-shields the exhaust section 2 and introduces heat generated in the exhaust section 2. The fluid filling port 8 is arranged on an opposite side of the water-cooling intercooler 4 across the heat-shielding member 6 and has a lower heat-resistance temperature than that of the water-cooling intercooler 4. The heat-shielding member 6 has a first end 6c to be an end in the longitudinal direction Q. In the heat-shielding member 6, the first end 6c faces the water-cooling intercooler 4 and is bent and formed to be separated from the fluid filling port 8 toward an upper side in the vertical direction G, and the first end 6c is provided with a gap from the water-cooling intercooler 4.SELECTED DRAWING: Figure 1

    【課題】簡素な構造で、排気部の熱をエンジンルームの上方へ逃がすことができる車両の放熱構造を提供する。【解決手段】車両の放熱構造1は、内燃機関10の排気部2と、水冷インタークーラ4と、遮熱部材6と、フルード注入口8と、を備える。水冷インタークーラ4は、排気部2よりも車両の上下方向Gの上方に配置される。遮熱部材6は、排気部2を車両Cの前後方向Qおよび車幅方向Pから覆い、排気部2を遮熱するとともに、排気部2で発生した熱を誘導する。フルード注入口8は、遮熱部材6を挟んで水冷インタークーラ4と反対側に配置され、水冷インタークーラ4よりも耐熱温度が低い。遮熱部材6は、前後方向Qの端部である第1端部6cを有する。遮熱部材6は、第1端部6cが水冷インタークーラ4に対向し、かつ、上下方向Gの上方に向かうにつれてフルード注入口8から離間するように折り曲げられて形成されるとともに、第1端部6cが水冷インタークーラ4と隙間を空けて設けられる。【選択図】 図1
