What should I do if the temperature is too low and the fin heater freezes and breaks?

In the process of using the finned tube, what should I do if there are problems such as icing or cracking? In other words, what is the reason? After knowing the reason, how should we solve it so as to avoid the same problem from happening again? Therefore, the following is very important. For finned tubes, we must read them carefully so that we can grasp them as soon as possible.

 

The reasons for the frost crack damage of the fin heater are summarized as follows:

 

1. Large margin for heat exchange area. When the finned tube is used in winter, the flow rate of the heat medium is too small, which causes icing inside the fresh air side coil, which will damage the finned tube through freezing and cracking.

 

2. The fin heater is improperly handled during installation and piping. There is water at the lowest point, which is easy to freeze in winter, which will damage the fin heater.

 

3. There is leakage inside the valve, otherwise the condensed water produced by the fin heater cannot be discharged smoothly, which will also cause the fin heater to freeze and be damaged.

 

Based on the above reasons, the solutions we can take are:

 

1. The heat exchange area of ​​the finned tube should not have too much margin. And if the heating area is much smaller than the cooling area, an air heater can be installed separately to avoid waste.

 

2. The air cooler is best placed behind the air heater to avoid this problem.

 

3. The installation and piping of the finned tube shall be carried out in accordance with the specified requirements and specifications, and shall not be operated in violation of the regulations.

 

4. The valve should be checked frequently. If it is damaged, especially the trap, it should be repaired or replaced in time.
