What Is A Plate Heat Exchanger


Definition Of Plate Heat Exchanger

The plate heat exchanger is a highly efficient heat exchanger that is stacked by a series of metal sheets having a certain corrugated shape. A thin rectangular passage is formed between the various sheets, and the heat exchange is performed by the sheet. The plate heat exchanger is an ideal device for heat exchange in liquid-liquid, liquid-steam. It has high heat exchange efficiency, small heat loss, compact structure, small area, wide application, long service life. In the case of the same pressure loss, the heat transfer coefficient is 3-5 times higher than the tube heat exchanger, and the area is one-third of the tubular heat exchanger, and the heat recovery rate can be as high as more than 90%.

Structural Principle Of Plate Heat Exchanger

  The structural principle of the plate heat exchanger is detachabled by many stamped ripple sheets, and is sealed through the gasket, and the sheet and pressure spiral are stacked, four sheets and gaskets. The angle hole forms a fluid dispensing tube and a collection tube, while separating the heat-insulating fluid reasonably to flow in the flow path on both sides of each sheet, and heat exchange. The plate heat exchanger is a new type of high efficiency heat exchanger that is stacked by a series of metal sheets having a corrugated shape. A thin rectangular passage is formed between the various sheets, and heat exchanged by half sheets. It is compared with the conventional tube-shell heat exchanger, in the case of the same flow resistance and pump power consumption, there is a lot of heat transfer coefficients, and there is a tendency to replace the tube-shell heat exchanger in the applicable range.

Basic Classification Of Plate Heat Exchanger

In general, we mainly district the panel heat exchanger according to the structure, which is divided into four categories according to the shape, can be divided into four categories: 1 detachable plate heat exchanger (also called a plate heat exchanger with sealed spacers), 2 welding plate heat exchanger, 3 spiral plate heat exchanger. Among them, the soldering sheet heat exchanger is also divided into: a semi-welded plate heat exchanger, a full welding plate heat exchanger, a plate heat exchanger, a brazing sheet heat exchanger.

 Storage Precautions Of Plate Heat Exchanger

  The plate heat exchanger is a certain particularity because of a rubber gasket. It should generally be carried out in accordance with the requirements of rubber, such as expanding light, ventilation, principle ozone, etc., and have a certain temperature and humidity requirement, when not in use, keep the gasket has a certain relaxation, not caused permanent deformation, keep it Elastic status. The following is some requirements for foreign companies to store the board exchange for reference. When the equipment is taken before use (more than 1 month), appropriate protective measures should be taken to prevent unnecessary losses in the device.

1: The equipment is preferably stored in the room, and the indoor temperature is from 15 ° C to 20 ° C (60 ° F to 70 ° F), and the humidity is about 70%;

2: Indoor can't have ozone equipment, such as electrodes, welding equipment, etc., ozone is destroyed for many rubber; cracking);

3: The organic capacity and acid solution cannot be stored indoors, and heat radiation and ultraviolet radiation should be avoided;

4: It is best to put it in the box before the device is installed;

5: The metal plate is preferably covered with an opaque plastic film;

6: Bolt surface should be painted with better rust fluid;

7: The heat exchanger should be emptied, and according to the media being treated, it is recommended to clean the drying before the device is stored.

8: Seal flange or take over, and close other openings;

9: Carbon steel surface takes rust, anti-corrosion travel;

10: Loosen the clamping column and in a non-drawn state.
