Description
Technical field
The heat-storing device that the present invention relates to paraffin-felt phase transformation thermal energy storage material and utilize paraffin-felt phase transformation thermal energy storage material to be prepared from.
Background technology
In the winter time when cold weather, people's custom electric hot-water bag is warmed oneself, 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, the mobility of water is strong, can scald people when electric hot-water bag leakage, and easily causes water bag expansion blast, can cause very large potential safety hazard to people.
The advantages such as paraffin has that physicochemical property long-term stability, heat accumulation rate are high, wide material sources, cheap, pollution-free, non-corrosiveness, be a kind of ideal phase-change heat-storage material, 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 also there is the research of wax phase change matrix material at present, as phase change composite materials etc. such as paraffin-graphite, paraffin-perlite, paraffin-vermiculites, the heat insulation effect, soaking time etc. of these phase change composite materials are all undesirable.
Felt has that adsorptive power is strong, stable molding, the feature such as heat insulation, but it there is no heat storage function, and thermal conductivity is little, felt can be burnt during heating, and after stopping heating, heat disappears very soon.
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 the heat-storing device utilizing paraffin-felt phase transformation thermal energy storage material to be prepared from, utilize paraffin for phase change material, be that absorption and supporting structure are prepared from felt, have than single paraffin and the beyond thought better heat-storage heat-preserving effect of water.
For solving the problem, the present invention is achieved through the following technical solutions:
Paraffin of the present invention-felt phase transformation thermal energy storage material, it, primarily of paraffin and felt composition, is flooded by paraffin felt being placed in fusing, after felt absorption is full, takes out cooled and solidified and is prepared from.
The PE wax of 10% is added by weight in described paraffin.
Described paraffin is refined wax or the SEMI-REFINED PARAFFIN WAX of fusing point 58-60 DEG C.
The invention still further relates to a kind of heat-storing device utilizing described paraffin-felt phase transformation thermal energy storage material to be prepared from, its outside paraffin-felt phase transformation thermal energy storage material with aluminium-foil paper or conventional high-temperature resistant membrane (as nylon film etc.) coated encapsulation.
At least two-layer paraffin-felt phase transformation thermal energy storage material is comprised in 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 for phase change material, be that absorption and supporting structure are prepared from felt, overcome the shortcoming of paraffin liquid phase flow and rapid heat dissipation, obtained paraffin-felt phase transformation thermal energy storage material light specific gravity, substantially do not flow, dimensionally stable, non-corrosiveness, and there is better beyond thought heat-storage heat-preserving effect.Add PE wax (stablizer), make paraffin melting after more not easily trickle.Use refined wax or the SEMI-REFINED PARAFFIN WAX of fusing point 58-60 DEG C, the heat-storage heat-preserving better effects if of paraffin of the present invention-felt phase transformation thermal energy storage material can be made.
Based on the paraffin prepared-felt phase transformation thermal energy storage material, with aluminium-foil paper or conventional high-temperature resistant membrane (as nylon film etc.) coated encapsulation outside paraffin-felt phase transformation thermal energy storage material, the mobility of paraffin can be made to reduce.At least two-layer paraffin-felt phase transformation thermal energy storage material is comprised in 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 adds the contact area of paraffin and heating element, better solve paraffin to conduct heat slow shortcoming, paraffin is heated relatively uniform, increase the quantity of heat storage of paraffin, power and energy saving more.Temperature control electronic package is formed primarily of thermostat and overtemperature prote safety fuse, the temperature of heat-storing device can be made to control 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 to may be used for the fields such as electric heating bag, warming shoe, incubation canteen, heat accumulation floor.
