Description
Technical field
The utility model belongs to new-energy automobile accessories field more particularly to a kind of cold water plate and the heating comprising cold water plate
Device.
Background technology
The problem of to cope with the contradiction of fuel oil supply and demand to become increasingly conspicuous and environmental pollution, countries in the world are promoting new energy
The development of automobile.The waste heat of one straight grip engine of orthodox car depends on the engine of automobile as heating heat source, this mode,
That is it could implement interior heating in the state that engine works.In addition, the efficiency of this heating system is very
It is low, need 6-10min that could heat after starting engine in winter.But electric vehicle does not have engine, hybrid vehicle
Car is also required to heat when to stall.
Currently, due to the distinctive positive temperature coefficient resistivity-temperature characteristics of PTC ceramics, have temperature automatically controlled, temperature is with voltage wave
It is dynamic to influence the excellent electrical property such as small and burn and the flames of anger, service life length etc. security feature.By PTC ceramics system
The ptc heater of work is a kind of ideal heating device, it is not only solved inside electric vehicle under cryogenic well
Heating and the required heat source of wind screen defrosting, moreover it is possible to be applied to the heat management system of power battery, in environment temperature
Power battery is heated when relatively low, and since its excellent insulation performance ensures the security performance of electric vehicle.
Electric vehicle heating ptc heater has wind to warm up two kinds of hot-water heating, and PTC water-warming heaters are with PTC heating elements
Fever core, is fabricated to PTC heating tubes, dedicated aluminium alloy heat carrier is inserted into, by heating and anti-freezing liquid, via evaporator
There is provided warm wind to car, warm wind is soft comfortable, temperature stablize it is moderate, it is safe to use, it is energy-efficient.In addition, PTC water heaters are also
It can be used for electric automobile power battery heat management system, heated to battery by heating and anti-freezing liquid.
There are following features in the ptc heater use environment that electric vehicle field uses：First, operating voltage is high, at least exist
320V or more, generally in 320VDC-750VDC；Second is that the voltage of electric vehicle is not constant in operation, but with
The loss of electricity in operation and decline；Third, since automobile is in outdoor application, the variation of temperature in four seasons and humidity is big；Fourth, this
Heater is mounted in automobile and uses, and needs better anti-shake performance, and the requirement higher to service life, need to reach 10 years with
On；Fifth, in order to ensure that electric vehicle is paddling, meeting with rainwater or the partly security performance of the extreme environments such as immersed, it is desirable that
The dust-proof water performance of ptc heater is preferably up to IP67, avoids the unexpected injury that interior or vehicle periphery personnel are caused with electric shock；Six
It is the PTC water-warming heaters of existing widely used similar Germany Ai Beihe structures currently on the market, has the disadvantage that：1, the knot
Structure safety defect：Ai Beihe heater structures are as follows, and PTC heating cores are inserted into die casting aluminium slot (as heat conduction sink), and aluminium slot is placed
In plastic shell, water (anti-icing fluid) flows between plastic shell and aluminium slot, and PTC heating cores pass heat by heating aluminium slot
It leads in water (anti-icing fluid).To prevent water (anti-icing fluid) from penetrating into the electric-controlled plate above the PTC heating cores or aluminium slot of electrification, it is necessary to
Reliable sealing is carried out between plastic shell and heat conduction aluminum sink, once sealing between the two goes wrong, anti-icing fluid is just
PTC heating elements or electric-controlled plate can be permeated and touched at faying face, and it is easy to appear the safe things that electric leakage causes in this way
Therefore.Therefore there are some potential safety problemss for the PTC water heaters of this structure.2, the cost disadvantage of the structure：Ai Beihe heaters
Structure is inserted into die casting aluminium slot structure using PTC heating cores, the material cost and cost of manufacture of PTC heating cores and die casting aluminium slot compared with
It is high；3, the structural thermal effect is poor：PTC heating cores are inserted into heat conduction aluminum slot, do not allow between the two easy to attach close, have caused phase
To larger thermal resistance, the heat conduction of PTC is affected so that the power of PTC is not easy to play.Seven separately have cisten mechanism currently on the market
Water-warming heater, have the disadvantage that in structure：1, for PTC heating cores by silicone adhesive between water flowing flat tube, water flowing is flat
Pipe and the hydroecium at both ends are by soldering connection, since PTC heating temperatures are at 200 degree or more, and the liquid in hydroecium and water flowing flat tube
Body (water or anti-icing fluid) temperature is very low (at 0 degree or less), and weld strength may be influenced for a long time by starting repeatedly, influence water
The leakproofness of case.2, PTC heating cores and the spaced structure of water flowing flat tube be since water flowing flat tube is flat and quantity is few, water resistance compared with
Greatly.
