[0021] The present invention will be further described in detail below with reference to specific embodiments.
[0022] Example:
[0023] like Figure 1-7 As shown, this utility model discloses an underground insulated food delivery vehicle, comprising a frame 1, a front-wheel drive system 2 connected to the bottom of the frame 1 via a front suspension, a rear wheel 3 connected to the bottom of the frame 1 via a rear suspension, a diesel engine 4 providing power to the front-wheel drive system 2, a cab 31 mounted on the frame 1, and a food container 5 located behind the cab. The food container 5 has a door 6 on its front, and multiple layers of heat-conducting plates 7 are provided inside the food container 5. Each heat-conducting plate 7 has an inner cavity, and an inlet 8 and an outlet 9 communicating with the inner cavity are provided on the heat-conducting plate 7. The diesel engine 4 has a coolant inlet 10 and a coolant outlet 11. The coolant outlet 11 is connected to the inlet 8 via a pipeline and a water pump. The outlet 9 is connected to the water inlet 13 of a radiator 12 via a pipeline. The water outlet 14 of the radiator 12 is connected to the coolant inlet 10 via a pipeline.
[0024] The coolant outlet 2211 is connected to an inlet distributor 15 via a pipe. The inlet distributor 15 is connected to an exhaust pipe cooling assembly and a turbocharger cooling assembly via branch pipes. The exhaust pipe cooling assembly and the turbocharger cooling assembly are connected to a return distributor 16 via branch pipes. The return distributor 16 is connected to the inlet 8 via a pipe.
[0025] The exhaust pipe cooling assembly includes a copper pipe 17 wound around the exhaust pipe 18 of the diesel engine 4, and the two ends of the copper pipe 17 are connected to the inlet diverter 15 and the return diverter 16 respectively through branch pipes.
[0026] The turbocharger cooling assembly includes a housing 19 welded and fixed to the surface of the turbocharger 20 of the diesel engine 4. A gap is left between the housing 19 and the surface of the turbocharger 20 to form a sealed cavity. The housing 19 is provided with an inlet 21 and an outlet 22. The inlet 21 and the outlet 22 are respectively connected to the inlet water distributor 15 and the return water distributor 16 through branch pipes.
