Thermal energy storage medium is used for being stored in the heat being generated by thermal source when it is connected to external power source, and in use heat being discharged into body care surface.Preferably, thermal energy storage medium has high hot memory density.There are three kinds of Main physical modes for thermal energy storage: sensible heat, phase transformation reaction and thermal chemical reaction.The variations in temperature of sensible heat storage based in material, and unit memory capacity equals thermal capacitance × variations in temperature.Sensible heat system generally has large thermal mass or requires large-temperature range.

When material changes its phase time in the time heating, generate heat of transformation storage; Along with phase transformation reverses, the heat of storing in phase transformation dissipates in the cooling procedure of material.The memory capacity of phase-change material equals the sensible heat of enthalpy of phase change under phase transition temperature+store in whole storage temperature range.

Phase Transition Systems generally has the energy storage density more much higher than sensible heat storage system.

Therefore, a kind of thermal energy storage medium of preferred form is phase-change material.Preferred phase-change material have per unit mass high latent heat of fusion (increase energy storage density), high specific heat, high-termal conductivity, high density and the most important fusing point under action required temperature range of other sensible heat storage effect are provided.Consideration in addition comprises safety (nonflammable, avirulence, non-explosive), non-aggressive, without chemolysis.The classification of phase-change material comprises organic material and inorganic material.Organic material includes but not limited to for example paraffin (C of wax _nh _2n+2) and fatty acid (CH ₃-(CH ₂) _2n)-COOH) for example lauric acid, stearic acid, pentoglycerine.These materials are generally chemically stable, have high melting heat, and safety is non-reacted, and can be recycled.But they can have the shortcoming of relative low heat conductivity in the time that it is solid-state, their volume latent heat memory capacity is relatively low.They can be inflammable.Particularly, paraffin can derive from many commercial source.These waxes generally do not have unique melting temperature.On the contrary, they have melting range.For example, can derive from (the Strahl & Pitsch of Stone Bi Si company of New York, United States Xi Babilunshi, Inc.West Babylon, New York, USA) a kind of material there is the melting range (fusing point is opened top cover pipe USP II class) of 122-127 ℉ (50-53 DEG C).Other paraffin can have the melting range that is up to 69-73 DEG C.

A problem of above identifying in phase-change material system is the remarkable change in volume in phase transformation and/or chemical reaction process.Therefore, may expect the material that adopts " pressure block " 411 (shown in Fig. 5 C) or can expand or shrink because of change in volume, described change in volume can be generated by air bag or thermal energy storage medium.Pressure block 411 can be attached to the separately item of cup or be integrated in the moulding process of hot body care element.Another object of pressure block is to help thermal energy storage medium is maintained in ad-hoc location for example near electric heater or on a sidewall of hot body care element.

Thermal energy storage medium can be selected because of its operating temperature range.Usually, operation that sensible heat system can be in temperature range very widely the scope of phase (it does not change thereon).When operating temperature range is crossed over phase transition temperature, when especially approaching and/or slightly exceeding the phase transition temperature of required hot compress temperature, Phase Transition Systems will have special effectiveness.

The amount of the thermal energy storage medium using in hot body care element determines the available volume by hot body care element and required thermal capacitance.In a preferred embodiment, comprise that for what use at the hand-held device with motion generation system approximately 1 to about 5g wax or wax mixture.More preferably, this embodiment can comprise that approximately 1 to about 3g wax or wax mixture.

example

example 1

Following is the example of measuring the Quality of Paraffin Waxes of the required caloric requirement that is provided for predetermined amount of time.For this example, value be similar to and be rounding to and be no more than 2 significant digits.In this example, we show that mensuration will soak pad (2 grams of water that retained by small-sized non-woven mat) and be heated to 40 DEG C and this heat is provided to the process of 120 seconds required systems from 20 DEG C.Quality, temperature range, thermal endurance and hypothesis based on water transferring heat to 50% efficiency of soaking in pad, we measure the energy that needs 450 joules (" J ").

In this example, we use such paraffin, and it has the specific heat of about 2000J/ (kg-DEG C) in liquid phase, the specific heat of about 1000J/ (kg-DEG C) in solid phase, with the melting heat of about 210000J/kg, and the melting range of about 53-57 DEG C.When soak pad for heating, we take the initial liquid phase temperature of approximately 60 DEG C, and the final solid-state temperature of approximately 40 DEG C.In order to provide 450J to pad, we measure need to about 0.002kg (2g) wax.

In order to store 450J heat energy in 2g paraffin, we measure the amount that 2g paraffin is heated to the required electric energy of the final liquidus temperature of about 55-60 DEG C from the initial solid-state temperature of 20 DEG C.For required electric energy is minimized, we select by use by wax around the heat conduction efficiency of internal electrical heater maximize.Operating efficiency based on hypothesis and the heat transference efficiency of hypothesis, we measure is about 1000J by the thermal energy storage of 450J required electric energy in 2g wax.Finally, we are made as the target time by wax heating 90 seconds.Therefore, providing and storing the required electrical power of heat energy is 1050J/90 second, or approximately 12 watts (" W ").

Whether the energy [power (W)=voltage (V) * electric current (I)] that required electrical power is provided in order to measure can provide in wireless, handheld care device, and we make following hypothesis and calculating.Suppose to use 1.5V single battery, the required electric current of generation 12W will be:

12W＝1.5V*I，

Or

I＝12W/1.5V，

Or

I=8 ampere

Because AA battery operates in the scope of milliampere (" mA "), will need a large amount of AA batteries.High capacity cell too greatly and too heavy and/or too expensive.Therefore, select for example external power source with 120VAC.In the time of 120VAC, required electric current is by low several orders of magnitude:

I＝12W/120V，

Or

I=0.1 ampere (100mA)

Therefore, external power source allows to use low current and therefore uses less parts.

example 2:

Following is the example of measuring the Quality of Paraffin Waxes required about the hot stone embodiment that is placed on skin 10 to 30 minutes.

Again, we use such paraffin, and it has the specific heat of about 2000J/ (kg-DEG C) in liquid phase, the specific heat of about 1000J/ (kg-DEG C) in solid phase, and the melting heat of about 210000J/kg, and the melting range of about 53-57 DEG C.When soak pad for heating, we take the initial liquid phase temperature of approximately 60 DEG C, and the final solid-state temperature of approximately 40 DEG C.We also suppose that heat energy is 1J/ second or 1W to be delivered to skin.Therefore,, for the persistent period of 10 minutes, need 600J heat energy.For the persistent period of 30 minutes, need 1800J.This causes the waxiness amount of about 2.5g (applying for 10 minutes) to about 8g (applying for 30 minutes).Certainly heating wax and heat is stored in to required electrical power in wax (with bulk container more) will be increased by example 1.
