Description
Technical field
The present invention relates to automotive field, particularly a kind of space compactness and the piping rational vehicle engine energy-saving pre-heating system of arranging.
Background technique
Along with the develop rapidly of automotive industry, automobile is seen everywhere, it for people's life and social development make since automobile cold in the situation that, to start be the large problem that people are concerned about, especially especially serious in this problem of the north, the winter of cold area, the startup of automobile is more difficult, for the temperature of rising antifreeze liquid, generally before cold start-up, need to toast automobile oil pan with blowtorch, this kind of method risk factor is higher, easily make machine oil rotten, and fire using in fields is roasting just more inadvisable sometimes, effect is bad, waste time and energy, and easily breaking out of fire or damage machine again, cause unnecessary loss.Heat or the device of electricity consumption lagging insulation is solved by electric preheating pipe, and automobile parking is in the place that has power supply, when starting, connect with the mains and come to engine warming up by electric heating tube or electric lagging, this quadrat method exists the problem of complicated operation, easily produces leaky simultaneously, causes motor charged, there is potential safety hazard, and preheat time is long and user cost is high, the electric heater of 220 volts of power supplys of this employing too relies on power supply, is difficult to practicality in the wild.
The preheater that adopts DC electrical source, is limited by storage battery electric weight, and heating effect is not obvious, even if there are some effects, has also strengthened the wearing and tearing of automobile because heating-up temperature is not high.Have data to record, subzero 5 degree of automobile, to the temperature-rise period of 80 degree, are equivalent to the wearing and tearing of 300 kilometers of distances of automobile running.In the vehicle preheater then occurring, the number of turns of electric heating tube only has a circle, and rate of heating is slower; The setting height(from bottom) of radiator directly affects the mounting point of preheater, the height of water level of water tank is lower than preheater water intake height, because impeller blade end face is level, when work, impeller suction is easy to cause preheater not intake not, and water outlet is positioned at upper shell side downside preheater can not be caused electric heating tube no-water dry combustion and damage by ponding; This preheater adopts the sealing of upper-lower casing end face press seal circle, due to expand with heat and contract with cold or seal ring aging, in use often can produce and leak, and cause preheater coil to damage or electric leakage; Because this preheater often can produce fault, can't differentiate motor and damage or fuse blows, need the whole preheater of dismounting to judge and to keep in repair, and also do not have product or the method that can address these problems to occur at present.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of vehicle engine energy-saving pre-heating system, solve big-and-middle-sized motortruck engine starts and needs preheating under low temperature condition, tradition preheater need utilize civil power, and the spatial position using is tied, can not saving power, and the waste heat of vehicle exhaust can not be recycled, this device just is slightly changed engine vent pipe, can utilize the waste heat of self discharging to overcome the above problems.
Technological scheme of the present invention is achieved in that
