を有していた。For this reason, the overall size of the cooling and heating equipment becomes large, resulting in high costs.In particular, when heat storage materials are used as heat insulators or home heaters, there is a demand for miniaturization. However, there was a problem in that it became large in size.

〔実施例］ 以下、図面に示すこの発明の実施例について説明する。〔Example] Embodiments of the invention shown in the drawings will be described below.
この発明は、複合蓄熱体を潜熱型蓄熱材と導電性高分子
材料とから構成するものであり、まず、この発明で用い
られる潜熱型蓄熱材の例としては、有機系にあっては、
炭素数が１０以上の直鎖状炭化水素、連鎖の高級アルコ
ール、連鎖の脂肪酸、連鎖の脂肪酸エステルなどがあり
、潜熱量は３０〜５０ｃａｌ／ｇである。In this invention, a composite heat storage body is constructed from a latent heat type heat storage material and a conductive polymer material. First, as an example of the latent heat type heat storage material used in this invention, in the organic type,
There are linear hydrocarbons having 10 or more carbon atoms, chain higher alcohols, chain fatty acids, chain fatty acid esters, etc., and the amount of latent heat is 30 to 50 cal/g.
また、無機系では多くの水和物にみられ、例えば、塩化
カルシウム・６水和物、炭酸ナトリウム・ＩＯ水和物、
硫酸ナトリウム・１０水和物、リン酸水素２ナトリウム
・１２水和物、硝酸亜鉛・６水和物、硝酸カルシウム・
６水和物、チオ硫酸ナトリウム・５水和吻、硝酸ニッケ
ル・６水和物、酢酸ナトリウム・３水和物等があり、潜
熱量は３０〜９０ ｃ ａ Ｉ ／ ｇである。In addition, it is found in many inorganic hydrates, such as calcium chloride hexahydrate, sodium carbonate IO hydrate,
Sodium sulfate decahydrate, disodium hydrogen phosphate decahydrate, zinc nitrate hexahydrate, calcium nitrate
There are hexahydrate, sodium thiosulfate pentahydrate, nickel nitrate hexahydrate, sodium acetate trihydrate, etc., and the latent heat amount is 30 to 90 ca I/g.
また、導電性高分子材料としては、高分子材料の中に導
電性粒子を充填することにより、体積固有抵抗値が１０
−３〜１０３Ω・ｌの材料を用いる。In addition, as a conductive polymer material, by filling the polymer material with conductive particles, the volume resistivity value can be increased to 10.
-3 to 103Ω·l material is used.
この場合、抵抗値は前記導電性粒子として金属を用いた
場合には、その充填量を変えることにより１０−３〜１
０３Ω・１の範囲で調整することができ、また、カーボ
ンブラックを用いた場合には１０’ −１０”Ω・Ωの
範囲となる。In this case, when metal is used as the conductive particles, the resistance value can be adjusted from 10-3 to 1 by changing the filling amount.
It can be adjusted in the range of 0.3Ω·1, and when carbon black is used, it is in the range of 10′-10″Ω·Ω.
上記の場合、導電性粒子の充填量が増えるにつれて抵抗
値が低くなり、そして、充填された導電性粒子の連鎖を
通して電気が流れることとなる。In the above case, the resistance value decreases as the amount of filled conductive particles increases, and electricity flows through the chain of filled conductive particles.
この導電性粒子分散モデルを第１図に示し、電圧の印加
方向は任意である。This conductive particle dispersion model is shown in FIG. 1, and the direction of voltage application is arbitrary.
また、導電性粒子を充填する場合でなく、第２図に示す
ように高分子材料１と導電性皮膜または金属板２との積
層を行なった場合であっても良いものである。Furthermore, instead of filling the conductive particles, the polymer material 1 and the conductive film or metal plate 2 may be laminated as shown in FIG.
上記の各場合の発熱量は通常のジュール熱であるので電
圧に比例し、電流の２乗に比例する・こととなる。Since the amount of heat generated in each of the above cases is normal Joule heat, it is proportional to the voltage and proportional to the square of the current.
蓄熱材の高分子材料への分散方法としては、高分子材料
が液状（オリゴマーまたは未架橋）または溶液の場合に
は、簡単な撹拌装置により混ぜることが可能である。As a method for dispersing the heat storage material into the polymeric material, if the polymeric material is liquid (oligomer or uncrosslinked) or solution, it can be mixed using a simple stirring device.
例えば、ＣＨｓ ＣＯＯＮａ ・３ Ｈｚ ＯＮａＨＰ
Ｏ，系蓄熱材の粉末（平均粒径０．１５ｍｍ）をＥＰＤ
Ｍのトルエン溶液に分散することができ、高分子材料が
ロールミルなどの混合機が使える場合、すなわち、ゴム
状物質であれば、このような方法でも良いものである。For example, CHs COONa ・3 Hz ONaHP
O, type heat storage material powder (average particle size 0.15 mm) is EPD
If the polymer material can be dispersed in a toluene solution of M and a mixer such as a roll mill can be used, that is, if it is a rubbery material, such a method may be used.
また、高分子材料中に分散しないで蓄熱材と積層したり
、蓄熱材を高分子膜（シート）で包み込んでも良いもの
である。Alternatively, the heat storage material may be laminated with the heat storage material without being dispersed in the polymer material, or the heat storage material may be wrapped in a polymer film (sheet).
但し、蓄熱材と複合する高分子材料は蓄熱材が加熱され
て液状となった時、その流失を抑制する機能をもってい
なければならず、そのために、高分子材料のガラス転移
温度が蓄熱材の融点よりも高いこと、高分子材料の融点
が蓄熱材の融点よりも高いこと、および、高分子材料は
熱硬化型または加硫可能なゴムであって三次元網目構造
であること、のうちの１つ以上の条件が必要となる。However, the polymeric material composited with the heat storage material must have the ability to suppress the loss of the heat storage material when it is heated and becomes liquid. The melting point of the polymer material is higher than the melting point of the heat storage material, and the polymer material is a thermosetting or vulcanizable rubber and has a three-dimensional network structure. One or more conditions are required.
また、保温材を用いる場合に、保温材は、一般的には熱
伝導率の小さいものが有効であり、高分子材料、セラミ
ックスおよび多孔質材料、不織布などが用いられる。保
温材を用いることにより、放熱速度を小さくすることが
できる。Furthermore, when a heat insulating material is used, it is generally effective to use a heat insulating material with low thermal conductivity, and polymer materials, ceramics, porous materials, nonwoven fabrics, and the like are used. By using a heat insulating material, the heat dissipation rate can be reduced.
したがって、蓄熱材から放出された熱が徐々に使えるよ
うになるので長時間に渡って所定の温度に保つことがで
きるが、この場合の温度上昇は低くなるものである。Therefore, the heat released from the heat storage material can be used gradually, so that a predetermined temperature can be maintained for a long time, but the temperature rise in this case is low.
