Abstract
A flexible uniform surface-heating device comprises electric heating paper 1, electrodes 2 and package material 3. The package material 3 can be single material or a composite layer of multiple materials. When ultrahigh heat conductivity material serves as the package material, heat generated by the electric heating paper is evenly and quickly transmitted to the surface to diffuse out. When thermal insulation material serves as the package material on optional one side, most of the heat can be controlled to pass on to the other side. The flexible uniform surface-heating device has the advantages that the flexible uniform surface-heating device is simple in structure and ultrathin; a pure resistance circuit is used, no optical radiation or electromagnetic radiation occurs, and heat efficiency is very high; surface heating is uniform; the flexible uniform surface-heating device can be cut into any shape as required and can also be provided with a central hole; and a damaged local region of the flexible uniform surface-heating device does not affect normal operation of other regions so that safety and reliability are improved.
Description
Technical field
The present invention relates to a kind of soft uniform surface electro-heat equipment.
Background technology
Some special occasions need to carry out homogeneous heating to certain area, such as the automobile power cell case.Battery product is because know-why is electrochemical reaction, and it is extremely responsive to ambient temperature.Cross when low when temperature, its chemism reduces, and causes the battery available capacity significantly to reduce even can't discharge and recharge, and irreversible variation occurs for serious also can cause battery electrolyte and both positive and negative polarity structure, has a strong impact on battery life.Simultaneously, the new-energy automobile power brick is comprised of a large amount of cells, and Dian Chi Cheng Group technology is very crucial, keeps numerous cell temperature even, and is extremely important to the whole efficiency for charge-discharge of battery pack, cycle life.Therefore under the low-temperature condition how effectively with heating of battery to being conducive in the battery operated temperature range, and whole homogeneous heating becomes an important topic of battery applications technology.The main battery case internal placement thermo electric material that adopts comes battery is heated in present battery applications technology.The wire profile of traditional electrical hot material metallic resistance silk has determined that it can't accomplish homogeneous heating when larger area is heated, and as long as in the middle of any point fracture just cause whole circuit to work, and be difficult to repair, can only wholely replace.As adopt the thermal radiation lamp heated, then there are the problems such as the heat efficiency is low, installing space is not enough.
Current composite material research has obtained breakthrough, mixes electric conducting material and paper or the fabric made, such as carbon fiber electric heating paper, so that unitary piece of material conduction and heating become possibility.Because not luminous after the energising of planar material, do not produce electromagnetic radiation, circuit is pure resistor element circuit, heating efficiency is high, does not impairedly among a small circle affect whole heating, and can be processed into as required arbitrary shape.Simultaneously, the maturation of thin-film material and metal foil, and the progress of coating processes can be controlled the encapsulated layer thickness of thermo electric material in 0.1mm, and the heater that therefore adopts this class material to make can be applied to many special occasions.
Summary of the invention
The present invention is directed to the deficiency of existing heater, utilize novel soft plane heating material, a kind of efficient heater is provided.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: electric calorifie installation is by electrothermal paper 1, and electrode 2 and encapsulating material 3 form.Encapsulating material can be a kind of material, also can be the composite bed of multiple material.When encapsulating material is the super-high heat-conductive material, the heat that sends on the electrothermal paper will be delivered to rapidly the surface uniformly, and to outdiffusion.When the encapsulating material of any side is heat-barrier material, then can control most of heat to the opposite side transmission.
The present invention has following functions characteristics: a, simple in structure, and profile is ultra-thin; B, pure resistor element circuit do not have light radiation, electromagnetic radiation, heat efficiency superelevation; C, face heating, homogeneous heating; D, can cut into as required arbitrary shape, can punch in the centre; E, Local Damaged do not affect other zone normal operations, and safety and reliability is high.
