In the previous article Xiaobian to introduce to youWhat is a spiral tube heat exchanger?What is its role and use？》Today Xiaobian will introduce you to different kindsSpiral tube heat exchangerHow does it work？

First, liquid spiral tube heat exchanger

It turns the fluid into a countercurrent, The hot liquid enters the inlet located in the middle of the heat exchanger and flows out from the center, and the cold liquid enters the inlet located next to the heat exchanger and flows out。Because of the countercurrent, the two streams of fluid in the heat exchanger can reach almost the same temperature;Horizontal, vertical or other direction or any other direction that may be set。

Two, condenser type spiral tube heat exchanger

Ideal for condensing large volumes of gases (under low pressure or vacuum) and gas/gas or other/liquid mixtures。 The hot liquid enters the inlet located at the upper part of the heat exchanger and flows vertically to the lower part, and the cold liquid enters the inlet located next to the heat exchanger and flows into the spiral channel。This type allows the gas mixture to be at a very low pressure loss on the shaft and to obtain a high flow rate through an airtight spiral channel。

Third, evaporator type spiral tube heat exchanger

This type is suitable for reboiling, especially under vacuum or low working pressure conditions, the principle is: can expand the cross-section of the evaporation part, reduce the height。Despite the large volume, the flow rate of the gas can be properly preserved。Friction and rotational pressure losses are minimized。

Fourth, steam spiral tube heat exchanger

The center of this type of heat exchanger is designed to evenly distribute a gas in an open spiral channel。The wide flange of the cover on the gas side prevents the direction of the gas passage from turning outwards。The non-condensing component forms a countercurrent with the cooling water after flowing through the smaller channel and then flows through the outer spiral channel。The cooling water enters the entrance of the main body and flows into the center, and then drains out through the outlet on the bottom cover。Controlled low temperature [local] cooling is particularly effective when condensing under vacuum conditions。

5. Spiral tube heat exchanger with top condenser

There is no need for large diameter tubes on the gas side, as this type of condenser is vertically mounted on the column, reactor or reactor。The gas enters the middle tube, flows in a spiral shape, and exits from the upper part。
