Product Introduction

The Gooseneck(swan neck)transformer radiators is a specially designed cooling solution featuring a unique curved structure. This design improves airflow and enhances heat dissipation efficiency, making it ideal for high-performance transformers.

Compared to traditional straight radiators, the gooseneck structure allows for better cooling circulation and space-saving installation. It is widely used in modern transformer designs where both efficiency and compact layout are required.

Radiastar radiator structure forms

(1)The radiator according to the installation divided into:PG stationary and PC detachable.
PG type:stationary,don’t use the flange,direct welding on transformer tank.
PC type:detachable,through the flange fixed to the transformer tank.
(2)The radiator according to the structure can be divided into:
Conventional type:the center is the same,for example PC3200-30/520
Gooseneck type:for example PC2600(2200)-33(2)/520 the center of the film is different,the film is divided into long films and shor films,and the short film are more than two pieces.
