Thermal insulation device of automobile diesel oil pipe

Abstract

The invention relates to a thermal insulation device of an automobile diesel oil pipe. The thermal insulation device comprises a vehicle-mounted power supply, first flow valves, an oil pipe, a thermal insulation circular pipe, a water tank, a cooling water pump, a cooling water pipe, a temperature sensor, an automobile controller, a heating resistance wire and a second flow valve, wherein the thermal insulation circular pipe is arranged on the outer side of the oil pipe, the heating resistance wire and the temperature sensor are placed between the thermal insulation circular pipe and the oil pipe, the cooling water inlet and outlet ends of the thermal insulation circular pipe is connected with the cooling water pipe, so as to form a cooling water pipeline, both ends of the cooling water pump are arranged in the cooling water pipeline, and the first flow valves are arranged on the cooling water pipe which is close to both ends of the thermal insulation circular pipe; the left side of the water tank is connected with the cooling water pipe, the right side of the water tank is connected with a cooling pipe in a diesel cooling system, and the left side and the right side of the water tank are communicated by virtue of the second flow valve; the vehicle-mounted power supply, the first flow valves, the second flow valve, the cooling water pump, the temperature sensor and the heating resistance wire are connected with the automobile controller. By using the thermal insulation device, the thermal insulation effect of the diesel oil pipe is effectively guaranteed, and the oil work efficiency is improved.

Description

technical field [0001] The invention relates to the field of heat preservation control of automobile oil delivery pipes, in particular to a heat preservation device for automobile diesel engine oil delivery pipes. Background technique [0002] As a traditional automobile engine, diesel engine has become an essential fuel for automobiles. However, diesel has its own inevitable defects, that is, its freezing point is low. When encountering cold weather, the temperature of diesel will become very high. If the temperature is low, the fluidity will become very poor. Therefore, it is necessary to propose a thermal insulation device for automobile diesel, which can improve the working efficiency of the diesel engine and improve the fuel combustion environment while increasing the temperature of the diesel. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a thermal insulation device for fuel delivery pipes of automobile d...
