A volumetric heat exchanger, also known as a storage‑type heat exchanger, uses high‑efficiency heat transfer tubes as its heat exchange elements. So what are the advantages of this type of heat exchanger? Here’s a brief overview:
1. The heat transfer coefficient is high: for water–water heat exchange, the overall heat transfer coefficient K increases by 80%, and the temperature drop of the heating medium rises by 35%; for steam–water heat exchange, K increases by 35%, and the temperature drop of the heating medium rises by 25%.
2. Heat exchange is more efficient; thanks to a specially designed flow‑diverting device, the stagnant and cold‑water zones within the tank are minimized, achieving a volumetric utilization rate of up to 95%.
3. The shell-side pressure drop is minimal and can be neglected, thereby maintaining the advantages of stable water supply, comfortable water usage, energy efficiency, and water conservation.
4. The vessel occupies a small footprint, requires minimal space for extracting the tube bundle, and allows for single‑direction tube removal, thereby saving floor space and facilitating design, operation, and maintenance.
5. Complete range of specifications, offering flexible and cost-effective selection. Particularly advantageous in applications where equipment height is severely constrained, providing greater design flexibility.
6. During steam–water heat exchange, when the condensate temperature is low, a steam trap may not be required on the condensate line.
There are many types of heat exchangers, such as floating-head heat exchangers, spiral heat exchangers, and volumetric heat exchangers. Each type has its own distinct characteristics, allowing users to select the most suitable option based on their specific needs.
