[0003] In cold weather such as winter, the temperature of diesel is low and its viscosity increases, making the fluidity of diesel poor. At this time, the engine that relies on diesel is prone to idling and unstable operation. However, the engine can only be heated by continuously starting the diesel engine to heat the diesel entering the engine. However, this process is relatively long, and some large vehicles cannot wait when they need to set off urgently. Therefore, it is necessary to design a diesel engine heater to solve this problem.

[0024] A partition 4 is sealed and fixedly connected to the inner wall of the heating tube 1, and the partition 4 divides the inside of the heating tube 1 into a water inlet chamber 5 and a water outlet chamber 6. A water inlet pipe 7 is fixedly connected to the upper inner wall of the water inlet chamber 5, and a water outlet pipe 8 is fixedly connected to the upper inner wall of the water outlet chamber 6. The upper end of the partition 4 is sealed and fixedly connected to the top of the heating tube 1, and the lower end of the partition 4 is separated from the bottom of the heating tube 1. Furthermore, the water inlet pipe 7 is connected to an external hot water pump to transport hot water into the water inlet pipe 7, and its connection and transportation method is the existing technology.
[0025] A plurality of diverter plates 9 are fixedly connected to the side wall of the heating tube 1. The side wall of the diverter plate 9 away from the heating tube 1 is in contact with the inner wall of the oil inlet cylinder 2. The side walls of two diverter plates 9 close to each other, the side wall of the heating tube 1 and the inner wall of the oil inlet cylinder 2 form a heating chamber 10.
[0026] A plurality of first tubes 13 are fixedly connected to the top of the oil inlet cylinder 2 , and an oil inlet pipe 14 is fixedly connected to the upper ends of the plurality of first tubes 13 .
[0027] Furthermore, the oil inlet pipe 14 is connected to an external oil pump, and diesel can be transported into the oil inlet pipe 14. The connection and transportation method is the existing technology. When the diesel enters the multiple heating chambers 10, under the separation effect of the multiple heating chambers 10, the hot water flowing through the water inlet chamber 5 and the water outlet chamber 6 can heat the diesel in each heating chamber 10, thereby maximizing the diesel heating rate.
[0028] The lower end of the oil inlet cylinder 2 is located above the bottom of the oil return barrel 3. A plurality of partition bars 11 are fixedly connected to the inner wall of the oil return barrel 3. The partition bars 11 are away from the side wall of the oil return barrel 3 and are in contact with the side wall of the oil inlet cylinder 2.

[0031] When diesel needs to be heated in cold winter, the external hot water pump is started, and then the external hot water pump can pump external hot water into the water inlet pipe 7, and then the hot water flows through the water inlet chamber 5 and the water outlet chamber 6 and then flows out through the water outlet pipe 8;
[0032] Then, the external oil pump is started to transport the diesel in the fuel tank to the oil inlet pipe 14, and then the diesel enters the multiple heating chambers 10 through the multiple first pipes 13. At this time, under the separation effect of the multiple heating chambers 10, the hot water flowing through the water inlet chamber 5 and the water outlet chamber 6 can heat the diesel in each heating chamber 10, and then the heated diesel will enter the engine through the multiple return oil chambers 12, the multiple second pipes 15 and the return oil pipe 16, so as to ensure the temperature of the diesel entering the engine, and avoid the existing technology that in cold weather such as winter, the engine can only be heated by continuously starting the diesel engine to heat the diesel entering the engine.
