【考案の詳細な説明】
この考案は、試料の温度試験や、温度センサの検定、校
正等に用いられる恒温液槽に関するものである。[Detailed description of the invention] This invention relates to a constant temperature liquid bath used for temperature testing of samples, verification and calibration of temperature sensors, etc.
従来の恒温液槽としては、第１図で示されるように液槽
１に液体２を収容し、液槽１の側方に仕切３を設け、こ
の仕切と液槽１の側壁との間にプロペラ４を設置してい
た。As shown in FIG. 1, a conventional constant temperature liquid tank stores a liquid 2 in a liquid tank 1, has a partition 3 on the side of the liquid tank 1, and has a partition between the partition and the side wall of the liquid tank 1. Propeller 4 was installed.
そして図示しない熱交換器により加熱又は冷却された液
体２ば、プロペラ４０回転により攪拌されて仕切３の下
部より送り出されるようになっていた。The liquid 2 heated or cooled by a heat exchanger (not shown) is agitated by 40 revolutions of the propeller and sent out from the lower part of the partition 3.
しかしながら、このような構造では、プロペラ４の液体
を押し７出す角度に対応した渦流が発生し温度分布を生
じやすい。However, in such a structure, a vortex flow corresponding to the angle at which the propeller 4 pushes the liquid 7 is generated, which tends to cause temperature distribution.
又、攪拌は部分的に行なわれるため攪拌効率が悪く、熱
交換器と液体との熱交換も液体の流れむらにより一定で
安定したものではなかった。Furthermore, since the stirring is carried out partially, the stirring efficiency is poor, and the heat exchange between the heat exchanger and the liquid is not constant and stable due to uneven flow of the liquid.
この考案の目的は、以−Ｌの点に鑑み、プロペラの吹出
し口の仕切の下部に流線形ノズルを設けるようにし、よ
り高精度な恒温液槽を提供することである。In view of the following points, the purpose of this invention is to provide a constant temperature liquid bath with higher precision by providing a streamlined nozzle at the lower part of the partition of the propeller outlet.
第２図は、この考案の一実施例を示す説明図である。FIG. 2 is an explanatory diagram showing an embodiment of this invention.
液槽１に液体２が収容され、この液槽１内の側方に仕切

ペラ４が設けられ、このプロペラ４の吹出口の仕切３の
下部にプロペラ４の径に合わせて絞りのある流線形ノズ
ル５が設けられている。A liquid 2 is stored in a liquid tank 1, a partition 3 is provided on the side of the liquid tank 1, a propeller 4 is provided between the partition 3 and the side wall of the liquid tank 1, and an air outlet of the propeller 4 is provided. A streamline nozzle 5 with a throttle that matches the diameter of the propeller 4 is provided at the bottom of the partition 3.
図示しない熱交換器により加熱又は冷却された液体２は
、プロペラ４の回転により流線形ノズル５により方向が
整えられ流速が一様にされ吹き出される。The liquid 2 heated or cooled by a heat exchanger (not shown) is blown out with its direction adjusted by the streamline nozzle 5 by the rotation of the propeller 4, and the flow velocity is made uniform.
第３図は、流線形ノズル５の一実施例を示す説明図で、
同図ａ、ｂ、ｃは、それぞれ平面図、正面図、左側面図
である。FIG. 3 is an explanatory diagram showing one embodiment of the streamline nozzle 5,
Figures a, b, and c are a plan view, a front view, and a left side view, respectively.
この流線形ノズル５の吹出口５ａに、複数枚の整流板６
が設けられている。A plurality of rectifier plates 6 are provided at the outlet 5a of the streamline nozzle 5.
is provided.
この整流板６の向きを上下に設けられた支軸により呵変
することにより、液体２の吹き出し流の方向をいっそう
整えることができ、流速も一様で均一なものとなり渦流
の発生も防止できる。By changing the direction of the current plate 6 using support shafts provided above and below, the direction of the blowout flow of the liquid 2 can be further adjusted, the flow velocity becomes uniform, and the generation of eddies can also be prevented. .
以上述べたように、この考案は、プロペラの吹出し口の
仕切の下部に流線形ノズルを設けるようにした恒温液槽
である。As described above, this invention is a constant temperature liquid bath in which a streamlined nozzle is provided at the bottom of the partition of the propeller outlet.
従って、プロペラによって送り出される液体は流線形ノ
ズルによって流れが一様なものとされるので、温度分布
の均一化が図れ、渦流の発生も防止でき、又、攪拌効率
の向上が図れ、熱交換も一様なものとなる。Therefore, the flow of the liquid sent out by the propeller is made uniform by the streamlined nozzle, which makes the temperature distribution uniform, prevents the generation of vortices, improves the stirring efficiency, and improves heat exchange. It becomes uniform.
又、流線形ノズルに整流板を設けるようにすると流れは
更に一様なものとされ渦流の発生はいっそう防止できる
。Furthermore, if a current plate is provided in the streamlined nozzle, the flow will be made more uniform, and the generation of vortices can be further prevented.
