Description
Technical field
The utility model relates to automobile exhaust gas UTILIZATION OF VESIDUAL HEAT IN, particularly a kind of phase transition heat accumulation unit utilizing engine exhaust waste heat.
Background technology
Due to the aggravation of energy resource consumption, vehicle energy saving problem receives increasing concern.At present, the Effective power that internal combustion engine exports only accounts for the sub-fraction of fuel combustion release heat, and I. C. engine exhaust is full of a large amount of heats as a kind of used heat.If reclaimed by the waste gas residual heat of heat recovery technology by internal combustion engine, so the efficiency of internal combustion engine will significantly promote.
At present, the cold start-up of automobile is mainly realized by independent cold-starting device, some cold-starting devices are realized by solenoid control distributive value, be difficult to accomplish low oil consumption and low emission in cold start-up and Re Che process, so the fuel consumption and emission characteristic of vehicle cannot be ensured, also cannot avoid the wearing and tearing of cold conditions process vehicle component simultaneously.Some cold-starting devices adopt Electric heating, this starting drive complex structure, and volume is large, and cost is high, is not easy to arrange.No matter which kind of cold-starting device above-mentioned in addition, it runs all needs the longer time and increases extra energy loss, could by automobile starting.
Utility model content
The purpose of this utility model is to provide a kind of phase transition heat accumulation unit and the method that utilize engine exhaust waste heat, solve that engine exhaust heat device volume in prior art is excessive, the problem of cold start-up or hot car overlong time, its structure is simple, volume is little, be convenient to arrange on vehicle.
The technical solution of the utility model is achieved in that a kind of phase transition heat accumulation unit utilizing engine exhaust waste heat, its technical essential is: this device comprises hot fluid pipeline, heat exchange fin, cold fluid pipe and sleeve, described hot fluid pipeline is connected with the exhaust pipe of engine, heat exchange fin is connected at described hot fluid pipeline extenal fixation, described heat exchange fin edge is provided with draw-in groove, cold fluid pipe clamp is connected in described draw-in groove, be outside equipped with sleeve at heat exchange fin and cold fluid pipe, between described hot fluid pipeline and sleeve, be provided with phase-change material.
Described heat exchange fin is ring-type fin.
Described sleeve and the end socket of sleeve are stainless steel, and the two ends end socket of sleeve and sleeve welds together.
Described hot fluid pipeline and cold fluid pipeline are copper tube.
Certain expansion clearance is left between described cold fluid pipe and draw-in groove.
Utilize a phase-transition heat-storage method for engine exhaust waste heat, comprise the steps:
Step 1: utilize the waste gas residual heat produced in vehicle traveling process to make phase transition heat accumulation unit accumulation of energy;
By hot fluid pipeline, heat is transmitted hot fluid tube wall and heat exchange fin, phase-change material absorbs heat, and temperature raises, and be converted to liquid state by solid-state, phase transition heat accumulation unit stores energy;
Step 2: when cold start-up or hot car, makes engine prewarming after the cold fluid flowing through phase transition heat accumulation unit is heated;
In cold start-up or hot car process, cold fluid enters phase transition heat accumulation unit and is heated, by heat after cold fluid within the engine heat release, reenter phase transition heat accumulation unit again to be heated, continue transferring heat to engine, along with the decline of phase transition heat accumulation unit temperature, phase-change material is converted to solid-state by liquid state, phase transition heat accumulation unit terminates the release of energy, realizes the pre-heat treatment to engine.
Heat exchange fin described in step 1 is annular fin.
Phase-change material described in step 1 is paraffin.
the beneficial effects of the utility model:the phase transition heat accumulation unit of the engine exhaust waste heat that the utility model proposes, comprises hot fluid pipeline, heat exchange fin, cold fluid pipe and sleeve, its structure is simple, volume is little, is convenient to arrange on vehicle.Phase transition heat accumulation unit of the present utility model, during engine running, utilizes phase-change material to reclaim the used heat of engine generation.When stopping, the used heat reclaimed can effectively be preserved, during startup vehicle, heat can be absorbed by the cold fluid flowing through engine, improve the temperature of engine body, even if like this under arctic weather, " warm engine " is also easy to start, and without the need to the cold-starting device of complexity, repeatedly cold start-up correspondingly also can be avoided the wearing and tearing of engine.
At low ambient temperatures, starting motor-driven vehicle chance is because of fuel condensation, the reason such as machine oil is sticky and cold start-up difficulty occurs.Along with the progress of technology, as the electric jet technology etc. of gasoline engine, made cold starting performance greatly improve, but the component wear etc. that cold start-up produces endanger still serious.Different from other assistant starting or preheating method, the pipeline start up by preheating using phase transition heat accumulation unit to carry out is the whole body of preheating before activation, whole organism temperature is improved, low-temperature cool starting difficult problem can not only be solved, and have good effect to alleviating component wear, reducing waste of fuel and reducing tail gas pollution.
