The surface cooler is a heat exchanger formed by metal tube (copper, steel) covered with aluminum sheet (double flanged) through hydraulic expansion tube. The product has light weight, fin and copper tube (steel tube) close contact, good heat transfer performance and air flow performance, suitable for water-cooled, cooling system, suitable for centralized cooling, heating air heat transfer. The device is widely used in heating, cooling, air conditioning, washing and drying equipment and dehumidification works. So, how to select an efficient, economical and practical table cooler? There are so many factors related to the selection of surface coolers.


The selection of surface coolers is mainly related to the following factors:

1. Flow rate of tuyere

In the process of using, the convection heat transfer of the air in the surface cooler can be strengthened by increasing the flow rate of the air outlet of the surface cooler, so that the temperature of the inner electrothermal element can be lowered, the service life of the inner element can be prolonged, and the cold and heat exchange can be facilitated. The gas inlet should be paid attention to during the operation. The flow rate of the mouth.

2. Appearance load

If we only change the load on the surface, if the wall temperature is too high, the wall temperature of the electrothermal element will show a linear change, affecting the service life of the surface cooler. If the wall temperature is too low, at the same time the heat exchanger power will also be reduced, therefore, when selecting the surface cooler, it is necessary to pay attention to the size of the external load.

3. Is there any air with other impurities?

No matter whether the temperature is high or low, air with other impurities or not, because the air is viscous, the gas Reynolds number decreases, making the intensity of air convection heat transfer significantly reduced, the surface temperature of the surface cooler will rise, heat loss will increase, resulting in the final work of the power affected.

Therefore, in the process of selecting or using the surface cooler, some factors mentioned above should be paid attention to so as to keep the surface cooler in good working condition. Therefore, the selection of the surface cooler and whether it can maximize the heat transfer efficiency, with the customer's use of the process and configuration of the wind turbine volume has a great relationship, the use of the environment directly determines the service life and effect.
