Magnesium-water heating equipment and technology of all-electric automobile

Abstract

The invention discloses a magnesium-water heating equipment and technology of an all-electric automobile and belongs to the technical field heating equipment and technology of all-electric automobiles. Magnesium powder and an inert lubricant are mixed according to a proportion to form a thick suspended state magnesium powder liquid mixture; an injecting pump safely conveys the suspended state magnesium powder liquid mixture to a reaction container for reaction with water in the reaction container so as to produce hydrogen as required in a controllable, continuous and uniform-speed manner; a heat energy generated by the reaction between the magnesium powder and the water directly heats the automobile, the generated hydrogen is supplied to a proton exchange membrane hydrogen fuel cell for power generation, and the electric energy sent out by the proton exchange membrane hydrogen fuel cell then drives a PTC (Positive Temperature Coefficient) heater for heating. The beneficial effects of the invention are that: the magnesium-water heating equipment and technology of the all-electric automobile have the advantages of being energy-saving, environment-friendly, simple and convenient in installation, safe to use, reliable in work, high in work efficiency, low in running cost, long in service life and the like; no pollutant discharge exists; the problem of influence from heating of current domestic all-electric automobile driving cab to travel distance is solved.

Description

technical field [0001] The invention belongs to the technical field of pure electric vehicle heating equipment and technology, and in particular relates to a device and a technology for providing heat energy by reacting metal magnesium powder and water without consuming electric energy of the pure electric vehicle. Background technique [0002] Energy conservation and environmental protection are the themes advocated by the whole world today, and pure electric vehicles will become an inevitable trend in the future development of the automobile industry. The pure electric vehicle has canceled the fuel engine, without the waste heat of the fuel engine, the heating of the cab will consume a large amount of electric energy, which seriously affects the mileage of the pure electric vehicle. [0003] There are currently three heating solutions for pure electric vehicles, namely, fuel-based heating, PTC semiconductor electric heating, and heat pump heating. The fuel-based heating s...

Problems solved by technology

The fuel-based heating solution will not affect the mileage, but it violates the environmental protection concept of pure electric vehicles; the heat pump heating solution and the PTC semiconductor electric heating solution both consume a lot of electric energy and affect the mileage

At present, some theories use active metals such as magnesium and aluminum to react with water to generate heat to heat the car. However, due to the following defects, there is only a theoretical possibility, and it cannot be combined with reality.

1. Magnesium powder is a flammable solid metal powder. Dry friction should be avoided when adding magnesium powder, so as to prevent the sparks generated by friction from igniting the magnesium powder; 2. The density of magnesium is higher than that of water, and the magnesium powder will gradually deposit on the bottom of the reaction solution, making it Both the reaction rate and the degree of reaction are reduced; 3. The heat generated is difficult to be exported; 4. It is impossible to achieve continuous and uniform hydrogen production on demand
