To provide a vehicular waste heat utilization device capable of stabilizing heating while effectively using waste heat of a heat source body.SOLUTION: An air-conditioning side flow passage 42 includes: an air-conditioning side bypass flow passage 54 connected to an air-conditioning side first connecting portion 42a provided on the upstream side of an air-conditioning side radiator 50 and an air-conditioning side second connecting portion 42b provided on the downstream side; and a first changeover valve 56 for switching between communication and shut-off between the air-conditioning side flow passage 42 on the upstream side of the air-conditioning side first connecting portion 42a and the air-conditioning side flow passage 42 on the downstream side and the air-conditioning side bypass flow passage 54. A vehicular waste heat utilization device 10 further includes a heat exchanger 70 provided across a cooling side flow passage 22 on the downstream side of a heat source body 26 and the air-conditioning side bypass flow passage 54 on the downstream side of the first changeover valve 56 and exchanging heat between a first heating medium and a second heating medium.SELECTED DRAWING: Figure 1

    【課題】熱源体の廃熱を有効利用しつつ暖房を安定させることができる車両用廃熱利用装置を提供する。【解決手段】空調側流路42には、空調側ラジエータ50の上流側に設けられる空調側第1接続部42aと下流側に設けられる空調側第2接続部42bとに接続される空調側バイパス流路54と、空調側第1接続部42aの上流側の空調側流路42と下流側の空調側流路42と空調側バイパス流路54の連通と遮断とを切り替える第1切替弁56と、が設けられる。車両用廃熱利用装置10は、熱源体26の下流側の冷却側流路22と第1切替弁56の下流側の空調側バイパス流路54とに跨って設けられて第1熱媒体と第2熱媒体との間で熱交換を行う熱交換器70を更に備える。【選択図】図1
