Antifreezing fluid waste-heat recycling and reutilization method for internal combustion engine

Abstract

The invention relates to an antifreezing fluid waste-heat recycling and reutilization method for an internal combustion engine. The antifreezing fluid in a water tank of the engine is delivered to a double-layer vacuum heat-preserving vessel through a pipeline of a miniature straight-flow pump pipeline; the double-layer vacuum heat-preserving vessel is arranged in an idle space around the internal combustion engine and is used for storing the heat energy from the antifreezing fluid in the running process of the internal combustion engine; and the miniature straight-flow pump is supplied with power from a battery jar of a motor vehicle, and the miniature straight-flow pump is connected with the double-layer vacuum heat-preserving vessel and the water tank through a pipeline. When the internal combustion engine stops working after working for a period of time, the antifreezing fluid in the water tank is introduced to the double-layer vacuum heat-preserving vessel through the straight-flow pump, and the waste heat is stored in the double-layer vacuum heat-preserving vessel to achieve the purpose of recycling the waste heat of the antifreezing fluid for the internal combustion engine; and when the internal combustion engine is started, the antifreezing fluid in the double-layer vacuum heat-preserving vessel is output to the water tank through the straight-flow pump, and the temperature of the internal combustion engine rises to achieve the purpose of reutilizing the waste heat. The invention is simple and skilful in design, energy-saving and suitable for various diesel locomotives.

Description

Technical field [0001] The invention relates to a method for recycling waste heat, in particular to a method for recovering waste heat of antifreeze generated during the operation of an internal combustion engine. Background technique [0002] When the internal combustion engine is working, the cylinder of the internal combustion engine will generate a large amount of heat energy. The prior art is to release this part of heat energy in the atmosphere, thus becoming waste heat. There are generally two ways to discharge this part of waste heat: one is to discharge to the atmosphere through circulating water pumps, coolers, and fans; the other is to directly discharge to the atmosphere from the exhaust pipe. This not only wastes energy, but also pollutes the environment. [0003] On the other hand, it is difficult for existing motor vehicles such as automobiles, tractors, and agricultural vehicles to start under low temperature conditions. Generally, when the temperature is in...
