<p style="font-family:Arial;">
Dear All,
</p>
<p style="font-family:Arial;">
<br>
</p>
<p style="font-family:Arial;">
<span style="font-family:Arial;">Does anyone know how to set up the immersed heat exchanger so that its heat transfer capacity can be increased?</span>
</p>
<p style="font-family:Arial;">
<span style="font-family:Arial;">My current setting is:</span>
</p>
<p style="font-family:Arial;">
<span style="font-family:Arial;">Exchanger type horizontal tube bank</span><br>
<span style="font-family:Arial;">Fluid 20% Ethylene Glycol solution</span><br>
<span style="font-family:Arial;">Multiplier for Natural Convection Correlation 0.6</span><br>
<span style="font-family:Arial;">Exponent for Rayleigh Number 0.25</span><br>
<span style="font-family:Arial;">Geometry Factor 1</span><br>
<span style="font-family:Arial;">Geometry Factor Exponent 0</span><br>
<span style="font-family:Arial;">Tube lnner Diameter 0.098 m</span><br>
<span style="font-family:Arial;">Tube Outer Diameter 0.105 m</span><br>
<span style="font-family:Arial;">wall Conductivity 1440 kJ/h m K</span><br>
<span style="font-family:Arial;">Tube Length 30 m</span><br>
<span style="font-family:Arial;">Number of Tubes 1</span><br>
<span style="font-family:Arial;">Header volume 0.0226 m3</span><br>
<span style="font-family:Arial;">Cross Sectional Area 0.0075 m2</span><br>
<span style="font-family:Arial;"><br>
</span><br>
<span style="font-family:Arial;">This setting will make it difficult for the cold energy of the fluid in the exchanger to be transferred to the water tank. </span>
</p>
<p style="font-family:Arial;">
<span style="font-family:Arial;">When the temperature difference between the <span style="font-family:Arial;white-space:normal;">fluid</span> in the <span style="font-family:Arial;white-space:normal;">exchanger</span> and the water outside is 5 <span style="font-family:Arial;white-space:normal;">°C</span>, the temperature of the fluid flowing into the <span style="font-family:Arial;white-space:normal;">exchanger</span> will only increase by 0.13 °C after it flows out. </span>
</p>
<p style="font-family:Arial;">
<span style="font-family:Arial;">So how should I change the above parameters to make the heat transfer ability of this exchanger stronger?</span><br>
</p>
