Between positive terminal and negative terminal, between heat-conducting aluminium pipe and the heater assembly encapsulating structure of integrated housing, it is all made of inserts
The technique of injection molding is attached；Diaphragm is assembled to the check valve lower case of check valve upper housing and integrated housing by assembly technology
Between structure.
The course of work of the invention:
When turbocharged engine work is in high load capacity operating condition, crankcase ventilation gas passes through high load capacity crankcase ventilation
Pipeline is flowed into from check valve upper housing nozzle, is entered in the check valve lower case structure of integrated housing after diaphragm, eventually by
Heat-conducting aluminium pipe outflow.At the check valve integrated heater device plug be powered after, electric current in order followed by positive terminal,
Positive spring, electrode plate, PTC heating element, heat-conducting block, negative spring, negative terminal constitute circuit closed with power supply and return
Road.Under the action of heating effect of current, the surface temperature of PTC heating element is promoted rapidly in a short time, the heat of generation
Amount is transferred to the heater assembly encapsulating structure surface of integrated housing by the transmitting of contact heat and heat radiation mode through heat-conducting block, then
Be transferred to and be embedded into heat-conducting aluminium pipe therein, heat-conducting aluminium pipe to the high load capacity crankcase ventilation gas flowed through in its length range with
Convective heat transfer and the mode heat gas of heat radiation, lift gas temperature.PTC heating element is thermistor form, resistance
Value sharply increases after increasing to a certain extent with temperature, until heating efficiency becomes pole when current loop being made to tend to off state
Low, PTC temp of heating element does not continue to rise, to prevent heat damage caused by infinitely increasing because of temperature.
Beneficial effects of the present invention:
1, flexible arrangement degree of the turbocharged engine crankcase ventilation system in vehicle cabin can be improved in the present invention；
2, the present invention can carry out non-removable with the air inlet pipeline before turbocharged engine turbocharger entrance
Connection is such as welded, to realize that engine voluntarily lets out the crankcase ventilation system under high load capacity operating condition by working condition
It fails to pinpoint a disease in diagnosis disconnected, to reduce vehicle staking-out work, reduces development cost；
3, the present invention can heat high load capacity crankcase ventilation gas, promote gas coming through temperature, effectively solve
Certainly pipeline and check valve ice blockage problem in crankcase ventilation system.
