A heat exchanger system and method includes a securing frame, a heat transfer core having heat transfer panels removably secured to the securing frame, the heat transfer panels optionally including a plurality of segment modules coupled together, and one or more filter screens removably secured to the securing frame at one or both of an inlet end or an outlet end. The heat transfer core is disposed between the inlet end and the outlet end.

The invention relates to a dry cooling tower that replaces traditional metal finned tubes with rectangular polymer bags. Three spacers are positioned between adjacent polymer bags to restrict buckling and minimize airflow resistance. This configuration enhances structural stability and improves heat dissipation while significantly reducing manufacturing costs compared to conventional designs. The design optimizes thermal performance while maintaining efficient cooling operation in industrial applications.

A plate includes: a main body; a flow channel provided in the main body and configured to flow inert gas therein; a cover configured to cover a surface of the main body where the flow channel is formed; a buried member buried in an opening of the flow channel, the buried member including a buried portion fixed to the flow channel and made of dense ceramic, and a flow portion held by the buried portion and configured to let the inert gas flow from an inside to an outside of the main body, at least a part of the flow portion being made of porous ceramic; and a plurality of through holes provided in the flow portion. A ratio of a diameter of an outer circumference of the buried portion to a diameter of a smallest circle among circles including all of the through holes is 1.2 or higher.
