Description
Technical field
The utility model relates to vehicle crankcase ventilating technology fields, and in particular to automobile-used triton pipe heater.
Background technique
Crank case vent heater belongs to automobile parts, is mounted on the engine of motor vehicles and connects crankcase and air inlet
Pipe.Gasoline or diesel motor are since burning can generate exhaust gas between the piston and cylinder of crankcase, wherein containing unburned object
Matter and nitrogen oxides and vapor.This exhaust gas and machine oil and other substances exist in the form of mist of oil.In the past, crankcase
The mixture of exhaust gas and engine oil can be directly discharged in environment by a pressure reducing valve.If crankcase is not divulged information,
Internal pressure can constantly increase when engine works, and may finally will lead to engine and cast anchor.Due to the exhaust gas of crankcase discharge
Containing harmful ingredient, especially nitrogen oxides, the closed ventilating system of crankcase has been directed in Europe at present and has been used newly
Exhaust emission regulations (standard of Euro3 to 6 of in September, 2014 publication).When temperature is lower than 4 degrees Celsius, in crankcase waste gas
The moisture (due to Water vapor condensation) contained will appear icing phenomenon, cause to occur in crankcase ventilation system a degree of stifled
Plug.Crank case vent heater just comes into being, and a strength is made for environmental protection, especially for diesel engine
Speech, its waste gas circulation control have become the important means for reducing discharged nitrous oxides.
The principle of work and power of crankcase heater is to convert electrical energy into thermal energy, and process is complete by the core of heater
At, it is also necessary to PTC thermistor is used, logical heat transfer heats entire heater and especially heats metal heat-dissipation block therein,
Being transported in turn needs air intake to be heated position, prevents triton pipe and air inlet pipe intersection ice blockage.
The heater for generating heat to designing using PTC heat source, there are two types of designs.
One is the elastic force using conductive metal electrode piece itself, PTC thermistor component are pressed on frosting, so
Thermal energy is by being evenly distributed to thermal energy on metal tube using the lesser thermal resistance of metal, metal on plastic conductive to metal tube afterwards
Pipe is directly contacted with the gas blowby of crankcase, heat transfer direction are as follows: PTC thermistor-electrode slice-plastic layer-radiating block.
For the heater of this structure since plastic material heating conduction is poor, the thermal resistance in heat transfer process at plastics is very big, causes
Heat accumulates at heat source, uses for a long time, electrode slice can oxidation corrosion due to overheat, eventually lead to product failure；And add
The thermal efficiency is low, and heating speed is slow.
Another kind is that PTC thermistor and electrode slice are composed " fever core assembly " and directly contact radiator, heat dissipation
There are one layer of plastics gas blowby is isolated inside device, prevents gas blowby from corroding PTC thermistor, heat transfer direction: PTC thermistor-
Electrode slice-radiating block-plastic layer.The radiator and plastic casing of the heater of this structure are integrally designed, because of the material of the two
The material coefficient of expansion has difference, can generate small gap in process of expansion and contraction, gently then increase thermal resistance, heat transfer efficiency is caused to drop
Low, heavy then plastics is caused to crack, gas blowby corrodes PTC thermistor, finally makes product failure.
Utility model content
Based on this, it is necessary to provide one kind can reduce the gap due to caused by material coefficient of expansion difference for the utility model,
Improve the automobile-used triton pipe heater of heat transfer efficiency.
In order to realize the purpose of this utility model, the utility model uses following technical scheme:
A kind of automobile-used triton pipe heater, including sheath, the radiator being embedded in the sheath, is installed on the sheath
The bayonet cap of interior at least two electrode slices, the heater and the connection sheath that are located between the electrode slice；It is described to dissipate
Mounting hole is offered on hot device, the sheath is extended with the mounting post through the mounting hole；Wherein an electrode slice abuts
The radiator.
Above-mentioned automobile-used triton pipe heater, fansink designs mounting hole, sheath extend mounting post through radiator
Mounting hole greatly strengthens the bond strength of radiator and sheath, to reduce to the maximum extent since the material coefficient of expansion is poor
Sheath and gap caused by radiator, prevent thermal resistance from improving, improve heat transfer efficiency, keep in process of expansion and contraction caused by different
The effective status of product.
In some of embodiments, the sheath is plastic sheath, and the plastic sheath is with the radiator to form altogether
Type mode is combined together, so that the plastic sheath is extended with the mounting post through the mounting hole.Plastic sheath and heat dissipation
Device uses co-injection molding, realizes that plastics fill the purpose of radiator, to reduce to the maximum extent since the material coefficient of expansion is poor
The gap expanded with heat and contract with cold and generated caused by different.
In some of embodiments, radiator is using machining molding.
In some of embodiments, the quantity of the mounting hole is multiple.Multiple holes can guarantee that sheath and radiator connect
It connects stronger.
In some of embodiments, the mounting hole has taper.Hole with taper can enhance radiator and sheath
Bond strength.
In some of embodiments, the surface of the electrode slice is equipped with salient point, and the salient point abuts the heater.Electrode
Salient point is arranged in the surface of piece, advantageously reduces the contact area of electrode slice Yu radiator, heater and bayonet cap contact, thus
In the case where applied force is constant, increase the contact pressure of electrical contact, improve binding force, reduces contact resistance, greatly increase whole
The service life of a heater.
