Description
Technical field
The present invention relates to a kind of heater, more particularly to a kind of new-energy automobile integrated form liquid heater.
Background technology
Traditional new-energy automobile liquid heater, has using PTC-ceramic as heater, also has using Electric radiant Heating Film conduct
Heater.Due to the performance that PTC-ceramic is excellent, such as power density is big, pressure-resistant good reliability, dry combustion method wide using voltage range
Also the features such as will not damaging, current ptc heater has obtained industry and has been widely recognized as, and standard as new-energy automobile is matched somebody with somebody
Part.
Heater structure in the market, it is general to be made using aluminum alloy die-casting technological, PTC is loaded into many of radiator
In individual groove, then this radiator is assembled in a plastic casing, makes heater.When product design power is below 6KW
When, be adapted to be parallel on controller pcb board with multiple small heaters, but when need it is high-power when (such as power be 12KW with
When upper), if used in parallel using multiple small heaters again, its volume will be than larger, and tie point also compares many, occupancy automobile
On space and install cumbersome, high cost.
Also have in addition and use three-back-shaped aluminium pipe structure, a flat aluminum pipe long is bent into three-back-shaped structure, then add PTC
Hot device is attached in the space between aluminum pipe, then is compressed PTC and aluminum pipe with metal platen, this Standard technics comparing fiber crops
Tired, due to increased metal platen, weight is also heavier, and maximum problem is water resistance than larger.
The structure of vehicle air warming core body is also borrowed, by PTC-ceramic, electrode slice etc., with polyimide insulative paper as exhausted
After edge material parcel, load in aluminum pipe and compress, then fill in the gap between water pipe, form PTC heats and water pipe is alternate
The structure of arrangement, the liquid of heating pipe the inside flowing after PTC heats heating powers.This structure power density compares
Height, but have disadvantages that.On the one hand, due to ptc heater and spaced (the i.e. PTC+ water pipes+PTC+ water pipes+PTC+ of water pipe
Water pipe), middle water pipe is heated by both sides PTC, causes the radiating effect of PTC poor, and PTC power is not in full use；
Further, since there is fit-up gap between water pipe, it is necessary to be compressed using impressed pressure, so as to produce water pipe gross distortion, cause
The stress or crack of water pipe and hydroecium weld, produce leakage hidden trouble.And additional pressure is difficult to compress in middle water pipe,
Cause thermal resistance between ptc heater and water pipe very big, making the power of PTC-ceramic cannot fully play.
In addition, in overall structure, the heating part of liquid heater typically is made into a part, water pump is used as another
Individual part, is then connected heater section and water pump using rubber tube, is eventually fixed on base.This structure is not only
Volume is big, weight weight, installs trouble, and because coupling part uses rubber tube, it is easily aging, so being easy to cold in heat expansion
Cause interface leak in the case of contracting.
The content of the invention
The present invention is aiming above mentioned problem, there is provided a kind of new energy vapour that ptc heater and water pump become one
Car integrated form liquid heater, has the advantages that small volume, easy for installation and security performance is high.
In order to realize above-mentioned technical purpose, above-mentioned technique effect is reached, the present invention is achieved through the following technical solutions：
A kind of new-energy automobile integrated form liquid heater, including water pump and ptc heater, the water pump and the PTC

Top and bottom set alumina ceramic substrate.
Further, the controller assemblies include PCBA heat sinks, PCBA seal boxes and installed in PCBA seal boxes
Interior PCBA controller.
Further, the upper surface of the heater plastic casing is provided with low pressure plug-in unit and high-pressure insert；The heater
Plastic casing is connected by the low pressure plug-in unit and the high-pressure insert with the PCBA seal boxes plug-in type.
Further, the side of the PCBA seal boxes is provided with low voltage connector and high-tension connector.
Its advantage is：
1st, ptc heater and water pump are integrated into an overall structure in the present invention, small volume is lightweight, easy for installation,
Cost is reduced, performance significantly improves.Multiple-layer stacked structure, current concentrate on center section, it is easier to excluded in debugging
Air, and may insure that the flow rate of water flow in every aluminum pipe is more uniform.
2nd, the design structure of PTC heating is that heater assembly and controller assemblies are separated in the present invention, prevents heater group
Part leak causes controller assemblies to leak electricity, and is also convenient for assembling and detecting and repair.
3rd, the both sides of PTC heats are respectively provided with water pipe, and contract type aluminium section bar is compressed, and is radiated more abundant.
4th, used as heat-conducting insulation material, thermal conductivity is obviously improved alumina ceramic substrate, and comprehensive heat radiation power improves 40%
More than.
