Description
Technical field
This be a kind of device on the vehicle take diesel engine as power, utilize heat in the high-temperature tail gas that diesel engine when work discharges to heat the diesel heating device used for vehicle of the temperature that improves vehicle-mounted fuel oil-diesel oil.In particular, relate to a kind of improvement of diesel heating device used for vehicle perfect.
Background technique
Traffic and transportation sector uses the automobile take diesel oil as fuel in a large number, along with the variation of season and temperature, in order to guarantee engine work, need to constantly change bavin oil grade.Under cryogenic conditions, diesel car promise can substitute high trade mark diesel oil with low trade mark diesel oil, namely expands the using scope of low trade mark diesel oil, and in energy shortage oil price high today, the energy-saving significance that it is far-reaching and the economic benefit of bringing are immeasurable.
Allow and can use the diesel oil of the low trade mark winter, current easier way is exactly to vehicle-mounted fuel heating, improves the temperature of diesel oil self.No matter how ambient air temperature changes, and can make it keep good flowing state.Search related data, adding at present temperature technique still has following a few class: the electric-heating technology that utilizes the electric energy of the finite energy that Vehicular direct-current power supply (storage battery, charging generator) provides to heat to oil supply gallery; Utilize the waste heat of cooling liquid in diesel engine body cooling system to the heating technology of diesel oil heating, but original cooling system is changed to the large combustion performance that also can affect engine fuel; Utilize the heat of the hot environment of engine exhaust pipe or the tail gas of discharge, or by diesel oil transport pipe straight cutting or make helical and put in exhaust duct; Or change outlet pipe trend, the tail gas of motor discharge is directly faced toward to the heating technology of diesel oil fuel reserve tank discharge; Or utilize oil-fired boiler heating+bis-fuel tank Starting mode etc.; These heating technologys all existing in varying degrees poor reliability, heating-up temperature dynamically to control, the large installation of volume is loaded down with trivial details, the deficiencies such as great potential safety hazard cannot thoroughly be isolated and have to engine exhaust road and diesel oil pipeline.
In addition, also has the scheme that adopts more advanced hot pipe conducting technology." diesel heating device used for vehicle " that propose as, China Patent No.: ZL201020626326.2 (document number CN20191608), although solved the problem that the controlled and diesel oil pipeline of heating-up temperature and air outlet flue are isolated, also has the following disadvantages in force:
1. the diesel heating device used for vehicle being combined into one by heat exchange casing, tail gas heat quantity collection casing and exhaust flow control casing three parts, although its can have two kinds of different (I) or (L) combining form to adapt to different installing space environment, but along with the motor surrounding space of electric spraying diesel Automobile Design is more and more compacter present situation, can be difficult to meet for the space that this diesel heaters is installed.
2. its air outlet flue import and export bore is single and less than normal, and the engine exhaust road bore that can not adapt to different capacity makes it reasonable connection, and likely causing local air flow resistance to increase affects engine performance.
3. the service condition that gravity field installs of must meeting the general heat pipe of axial thermal conductivity adopting has limited the adaptive capacity to environment of this diesel heating device used for vehicle.
4, flow control regulator plate drives the gear pair of use owing to being subject to the restriction of left and right adjusting plate spindle central distance, and driving gear wheel set exists the possibility of gear teeth fracture or gear splitting, will bring hidden danger to equipment safety operation.
Summary of the invention
For the deficiencies in the prior art part, the object of this invention is to provide a kind of diesel heating device used for vehicle, its air outlet flue interface can directly be connected with vehicle motor air outlet flue, can be the installation of 360 ° of rotation any directions of axis take center, engine exhaust road, and by the fuel oil supply system of oil connection connecting engine, when engine operation, can heat fuel oil by the tail gas heat quantity discharging after engine combustion, by exhaust flow controlling unit realize heating, stop heating and heating-up temperature regulate manipulation.
The present invention is achieved in that diesel heating device used for vehicle, be formed by connecting by tail gas heat quantity collection commuting case and exhaust flow control box that branched concentric radial heat pipe is installed, tail gas heat quantity collection exchange casing has tail gas access way mouth and diesel pipeline connection interface, exhaust flow control casing has air outlet flue connection interface and tail gas access way mouth, the tail gas heat quantity collection exchange tail gas access way mouth of casing and the corresponding connection of tail gas access way mouth of exhaust flow control casing communicate, and diesel oil pipe-line system and exhaust gas channel are fully isolated.
On the basis of technique scheme, the present invention also has following further technological scheme:
Radial heat pipe outer tube has fin with one heart.
Head, tail after branched radial heat pipe inner tube is connected in series are connected with engine fuel supply system by pipe joint respectively.
