Description
【発明の詳細な説明】 ＜産業上の利用分野＞ この発明は理科学機器として汎用される加熱型恒温槽
に関するものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a heating-type constant temperature bath generally used as a scientific instrument.
＜この発明が解消しようとする問題点＞ 加熱型恒温槽を例えば第４図に示すように底部の熱源
板上に載置するときは、熱源板及び恒温槽の細かな凹凸
や互いの円曲等によって両者間が点接触となって恒温槽
への熱伝導が一様に行われず、従って恒温槽全体の温度
分布を均一に保つことができないという問題がある。ま

題がある。本発明はかゝる問題点を解消しようとするも
のである。<Problems to be Solved by the Invention> When a heating-type constant temperature bath is placed on a bottom heat source plate as shown in FIG. 4, for example, fine irregularities in the heat source plate and the constant temperature bath and mutual circular curvature For example, there is a problem that the two are in point contact with each other and heat transfer to the constant temperature bath is not performed uniformly, so that the temperature distribution of the entire constant temperature bath cannot be kept uniform. There is also a problem that heat conduction from the heat source plate to the thermostat is slowed down. The present invention seeks to eliminate such problems.
＜発明の構成＞ 本発明は加熱用の熱源板と、該熱源板に相対する恒温
槽の一面との間に前記両者を面接触させるための弾性を
もった熱伝導シートを挟入したことを特徴とする加熱型
恒温槽にある。<Structure of the Invention> The present invention provides that a heat conductive sheet having elasticity for bringing the two into surface contact is interposed between a heat source plate for heating and one surface of a constant temperature bath opposed to the heat source plate. Features a heating type thermostat.
＜実施例＞ 以下アルミブロック恒温槽にて実施例を説明する。<Example> Hereinafter, an example is described using an aluminum block thermostat.
ケーシング１の内底面に熱源板として加熱用ヒーター
プレート２と、該上に弾性をもった熱伝導シート３を接
面して敷着し、熱伝導シート３上にアルミブロック恒温
槽４を出入れ交換自在に嵌入するのである。A heater plate 2 for heating as a heat source plate and a heat conductive sheet 3 having elasticity are laid on the inner bottom surface of the casing 1 so as to be in contact with each other. It fits interchangeably.
熱伝導シート３としては熱伝導性にすぐれ、弾性を有
して且つ耐熱温度の高い例えばキメのこまかいシリコン
ゴムシートが用いられる。As the heat conductive sheet 3, for example, a fine-grained silicon rubber sheet having excellent heat conductivity, elasticity and high heat resistance temperature is used.
＜作 用＞ アルミブロック恒温槽４を嵌入すると、その重量によ
って熱伝導シート３を押すために、槽４及びヒータープ
レート２に凹凸があったり、また円曲によって両者間に
間隙が散在していてもシート３が間隙に押入って埋める
ため、ヒータープレート２と槽４間は熱伝導シート３を
挟んで全面が均しく接する面接触となって、ヒータープ
レート２による加熱はアルミブロック恒温槽４の底面全
面に均しく伝達されて試験管等の挿し立て孔Ａ、Ｂ、
Ｃ、Ｄ、Ｅの温度分布を均一とする。<Operation> When the aluminum block thermostat 4 is inserted, the heat conductive sheet 3 is pushed by its weight, so that the bath 4 and the heater plate 2 have irregularities, and gaps are scattered between the two due to the curved shape. Also, since the sheet 3 is pressed into the gap and filled, the heater plate 2 and the tank 4 are in surface contact with the entire surface in contact with the heat conductive sheet 3 therebetween. Inserted holes A, B,
The temperature distribution of C, D, and E is made uniform.
＜発明の効果＞ 本発明は以上のようにして、加熱用の熱源板と恒温槽

生ずる。また熱源板から恒温槽への熱伝導が促進され
て、恒温槽の加熱が早められるという効果を生ずる。<Effects of the Invention> In the present invention, as described above, the elastic fine textured heat conducting sheet is interposed between the heat source plate for heating and the constant temperature bath, so that the heat source plate and the constant temperature bath As a result, the heat source plate uniformly heats the entire surface of the thermostat so that the temperature distribution in the thermostat can be made uniform. In addition, heat conduction from the heat source plate to the thermostat is promoted, so that the heating of the thermostat is accelerated.
