The product introduction of fin - tube coolers and power station oil coolers of YDA in Dalian, China.

Basic Structure: The fin - tube serves as the fundamental heat - transfer element, consisting of a base tube and fins. The base tube is typically round, yet elliptical and flat tubes are also available. Fins have surface structures such as plain fins, interrupted fins, corrugated fins, and perforated fins.

Working Principle: High - temperature media, like hydraulic oil or high - temperature water, are introduced into the tube. A fan forces air to pass through the fins outside the tube, enabling the surrounding air to carry away the heat of the medium inside the tube, thus reducing the temperature of the medium.

By Material: It can be classified into stainless - steel air coolers, bimetallic air coolers, steel - aluminum composite air coolers, etc.

By Manufacturing Process: It can be classified into wound - fin air coolers, rolled - fin air coolers, integral fin - tube coolers, welded fin - tube coolers, high - frequency welded fin - tube coolers, etc.

Efficient Heat Exchange: The existence of fins significantly increases the heat - transfer area, improves the heat - exchange efficiency, and effectively reduces the temperature of the medium in the tube.

Strong Adaptability: Different materials and fin forms can be selected according to various usage environments and medium requirements. For instance, stainless - steel materials can be chosen in corrosive environments.

Convenient Installation: With a relatively simple structure, it is easy to install and maintain, and can be flexibly arranged according to space and process requirements.

Environment - friendly and Energy - saving: Usually, air is used as the cooling medium, eliminating the need for additional coolants, which is both environmentally friendly and energy - saving.

Basic Structure: Generally, it is composed of a shell, a tube bundle, a tube sheet, a head, and seals. The pipes in the tube bundle are used for oil circulation, and the space between the shell and the tube bundle forms the passage for the cooling medium.

Working Principle: Heat exchange is carried out by leveraging the temperature difference between the cooling medium (water or air) and the oil to lower the oil temperature. This ensures that the lubricating oil or hydraulic oil in power - station equipment is within an appropriate temperature range, guaranteeing the normal operation of the equipment.

By Cooling Medium: It can be classified into water - cooled power station oil coolers and air - cooled power station oil coolers.

By Structural Form: It can be classified into tubular oil coolers and plate - type oil coolers, etc.

High Reliability: It has reliable sealing and stability, enabling it to operate stably in the long - term and high - load operating environment of the power station. This ensures the normal operation of the oil - cooling system and the safety and reliability of power - station equipment.

Strong Cooling Capacity: It can rapidly reduce the oil temperature to the appropriate range, meeting the strict requirements of power - station equipment for oil temperature. Even under high - temperature conditions such as full - load operation of the power station, it can effectively dissipate heat.

Good Corrosion Resistance: Considering the special nature of the power - station environment, it is usually made of corrosion - resistant materials such as stainless steel to prevent the cooler from being corroded and extend its service life.

Customizable: It can be custom - designed and manufactured according to different power - station equipment, working conditions, and cooling requirements to meet personalized needs.
