According to the paraffin-felt phase-changing composite heat storage material, paraffin is adopted as a phase-changing material, the felt is used as an absorption and support structure to prepare the material, thus the defects of flowing paraffin in a liquid phase and rapid radiation are overcome, and the prepared paraffin-felt phase-changing composite heat storage material has the advantages of a light proportion, fundamental non-flowing, a stable shape, zero corrosion and better and unexpected effects on heat storage and heat preservation.
Description
Technical field
The present invention relates to paraffin-felt phase transformation thermal energy storage material and utilize the heat-storing device that paraffin-felt phase transformation thermal energy storage material is prepared from.
Background technology
In the winter time when cold weather, people's custom is with the electric hot-water bag heating, and electric hot-water bag becomes the indispensable article for keeping out cold of people.But electric hot-water bag adopts water as heat-storage medium, and the flowability of water is strong, can scald the people when the electric hot-water bag leakage, and causes easily water bag expansion blast, can cause very large potential safety hazard to people.
Paraffin has the advantages such as physicochemical property long-term stability, heat accumulation rate height, wide material sources, cheap, pollution-free, non-corrosiveness, is a kind of comparatively desirable phase-change heat-storage material, and people attempt using it to replace water as heat accumulating.But single paraffin has liquid phase flow, the shortcomings such as slow and rapid heat dissipation of conducting heat.Although the research of wax phase change matrix material is also arranged at present, such as phase change composite materials such as paraffin-graphite, paraffin-perlite, paraffin-vermiculites etc., the heat insulation effect of these phase change composite materials, soaking time etc. are all undesirable.
Felt has that adsorptive power is strong, stable molding, the characteristics such as heat insulation, but it there is no heat storage function, and thermal conductivity is little, felt can be burnt the very fast disappearance of heat behind the stopped heating during heating.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming, a kind of paraffin-felt phase transformation thermal energy storage material is provided, and utilize the heat-storing device that paraffin-felt phase transformation thermal energy storage material is prepared from, utilize paraffin to be phase change material, take felt as absorption and supporting structure be prepared from, have than single paraffin and the beyond thought better heat-storage heat-preserving effect of water.
For addressing the above problem, the present invention is achieved through the following technical solutions:
Paraffin of the present invention-felt phase transformation thermal energy storage material, it mainly is comprised of paraffin and felt, floods by felt being placed the paraffin of fusing, after felt absorption is full, takes out cooled and solidified and is prepared from.
In described paraffin, add by weight 10% PE wax.
Described paraffin is fusing point 58-60 ℃ refined wax or SEMI-REFINED PARAFFIN WAX.
The invention still further relates to a kind of heat-storing device that described paraffin-felt phase transformation thermal energy storage material is prepared from that utilizes, it coats encapsulation in paraffin-felt phase transformation thermal energy storage material outside with aluminium-foil paper or high-temperature resistant membrane commonly used (such as nylon film etc.).
Comprise two-layer at least paraffin-felt phase transformation thermal energy storage material in the described heat-storing device.
Position between described paraffin-felt phase transformation thermal energy storage material is two-layer arranges fever tablet and temperature control electronic package.
Paraffin of the present invention-felt phase transformation thermal energy storage material, utilize paraffin to be phase change material, take felt as absorption and supporting structure be prepared from, overcome the shortcoming of paraffin liquid phase flow and rapid heat dissipation, prepared paraffin-felt phase transformation thermal energy storage material light specific gravity, substantially flow, dimensionally stable, non-corrosiveness, and have better beyond thought heat-storage heat-preserving effect.Add PE wax (stablizer), more be difficult for trickling after paraffin is melted.Use refined wax or the SEMI-REFINED PARAFFIN WAX of 58-60 ℃ of fusing point, can make the heat-storage heat-preserving better effects if of paraffin of the present invention-felt phase transformation thermal energy storage material.
Take the paraffin for preparing-felt phase transformation thermal energy storage material as the basis, coat encapsulation in paraffin-felt phase transformation thermal energy storage material outside with aluminium-foil paper or high-temperature resistant membrane commonly used (such as nylon film etc.), can be so that the flowability of paraffin reduces.Comprise two-layer at least paraffin-felt phase transformation thermal energy storage material in the heat-storing device, and the position between paraffin-felt phase transformation thermal energy storage material is two-layer arranges fever tablet and temperature control electronic package, this mode has increased the contact area of paraffin and heating element, better solved the slow shortcoming of paraffin heat transfer, it is relatively even that paraffin is heated, increase the quantity of heat storage of paraffin, more the power and energy saving.The temperature control electronic package mainly is made of thermostat and overtemperature prote safety fuse, can make the temperature control of heat-storing device safer.
A kind of paraffin of the present invention-felt phase transformation thermal energy storage material, and utilize the heat-storing device that paraffin-felt phase transformation thermal energy storage material is prepared from can be used for the fields such as electric heating bag, warming shoe, incubation canteen, heat accumulation floor.
