Description
Technical field
The present invention relates to vehicle PTC liquid electric heater, be particularly applicable to the PTC liquid electric heater of new-energy automobile, and its autocontrol method.
Background technology
Vehicle PTC liquid electric heater, that the anti-icing fluid flowed by heat cycles is promoted air themperature, the maintenance battery temperature in compartment or provides the Multipurpose electric heater of required thermal source for other, in the winter of severe cold, being the most important electrical-heating source of air conditioning for automobiles heating system and heating of battery heat-insulation system, is also that automobile reaches defrosting laws and regulations requirement and guarantees the vitals of battery charging and discharging safety.
Because new-energy automobile is all work under high voltage condition; and electric quantity consumption and discharge and recharge safety be all important index; therefore very high to the power conservation requirement of PTC liquid-type electric heater; it is except requiring the heating function of general PTC liquid-type electric heater; the more important thing is and want to realize intelligent accurately control; there is desirable temp. control function, the functions such as power supply counnter attack, overvoltage protection, under-voltage protection, overtemperature prote, overcurrent protection, current-limiting protection, power adjusting, soft start, communication be had.
Whether energy-conservation the structure of PTC liquid electric heater itself, on thermal efficiency height with also have important impact.Existing new-energy automobile PTC liquid electric heater structure, as illustrated in the accompanying drawings from 1 to 3, PTC heats 1-1 is connected in the top 1-2 holding balancing boom device, PTC heats 1-1 puts into as holding in the lower casing 1-3 of anti-icing fluid, one group of offside of lower casing 1-3 offers liquid-inlet (IGBT assembles direction) 1-4, outlet 1-5 respectively, directly define fluid passage 1-6 between lower casing 1-3 inside and PTC heats 1-1 surface, anti-icing fluid forms flow direction by import 1-4, passage 1-6, outlet 1-5.As can be seen here: the sealing surface 1, between top 1-2 and lower casing 1-3 wants reliable, because anti-icing fluid constantly stands cold and hot exchange, the possibility that sealing surface produces leakage point increases; 2, fluid passage 1-6 is more roomy, and heat temperature raising speed is slow.
Summary of the invention
Goal of the invention: for the problems referred to above, the object of this invention is to provide and be a kind ofly applicable to the efficient heat transfer of new-energy automobile, energy-conservation PTC liquid electric heater, provide a kind of autocontrol method to electric heater simultaneously, can intelligently accurately control.
Technical scheme: a kind of energy-efficient new-energy automobile PTC liquid electric heater, comprise the upper body holding balancing boom device, the ptc heater core body be connected with described upper body, hold and the container of the anti-icing fluid that circulates, lower case, described container is made up of some aluminium flat conduit gap arrangement, described aluminium flat conduit two ends form fluid inlet line by aluminium header, outlet conduit, described ptc heater core body is inserted in the gap between described aluminium flat conduit, described lower case is enclosed within described external container and fixes with described upper body, described inlet pipeline, described outlet conduit is through described lower case.
The container that electric heater is supplied to anti-icing fluid circulation is independently, and directly do not contact with ptc heater core body or miscellaneous part, container does not have risk of leakage, even if anti-icing fluid constantly stands cold and hot exchange, and also durable leak-proof; The circulation passage that each aluminium flat conduit is formed simultaneously is independently, and flow is fixed, and is heated by adjacent ptc heater core body, can not produce the impact that heating is uneven, speed differs because of changes in flow rate; And the circulation passage that aluminium flat conduit is formed is partially narrow shape, adjacent ptc heater core body heating makes its programming rate obviously accelerate, under same anti-icing fluid container volume, the quantity that this aluminium flat conduit is arranged increases relatively, namely more circulation passage can be formed, heating surface area significantly increases, and improves programming rate.
Described aluminium flat conduit cross section is that single hole or porous are irregularly shaped, and passage gaps is 0.5 ~ 50mm.
Described ptc heater core body and described aluminium flat conduit adopt viscose glue and fix rear heating cure by fixture.
Described ptc heater core body and described aluminium flat conduit adopt polyimide insulative film or alumina ceramic chip or silica gel piece to insulate to separate.
Described aluminium flat conduit welds with described aluminium header or riveting or one-body moldedly to make.
A kind of above-mentioned energy-efficient new-energy automobile PTC liquid electric heater autocontrol method, adjustment controller dutycycle regulates ptc heater core body heating power and realizes controller soft and starts: import and export water temperature by detecting PTC liquid electric heater incessantly in real time, to judge to need to increase or reduce ptc heater core body heating power, thus adjustment controller dutycycle increases or reduces, and realizes step-less adjustment PTC liquid electric heater heating power; By progressively increasing controller dutycycle to increase electric current, realize the size of adjustment control inrush current.
Beneficial effect: compared with prior art, advantage of the present invention is the structure by improving vehicle PTC liquid electric heater, improves heat exchange efficiency, thus reaches Fast Heating and energy-conservation object, greatly reduce the possibility that anti-icing fluid leaks simultaneously, durable in use; The mode that existing gear regulates is abandoned to the autocontrol method of power adjusting, has achieved the step-less adjustment of Electric automatic control, and reach the object of soft start.
