PURPOSE: To provide a food-warming device keeping heat by utilizing heat of cooling water for engine of a food delivery vehicle. CONSTITUTION: A food delivery vehicle 1 comprises a cooling circuit 5, a heat exchanger 6, an engine cooling device 4 having a pump 7 circulating coolant, and a body for food transfer 3. A heat-insulated case 10 having, inside, supporting means for storing food and forming a heat-insulated warming chamber is provided in the vehicle. A radiator 24 as a heat exchanger is provided inside the heat-insulated case 10. Also, a fan 25 removing heat from the radiator 24 and diffusing it into the warming chamber is provided, and food heating circuits 6, 24, 29, 30, 31, 32, 33, and 34 allowing the coolant to circulate from a combustion engine 2 to the engine cooling device 4 through the radiator 24 inside the heat-insulated case 10 are also formed in the vehicle. |
