METHOD AND SYSTEM FOR MANUFACTURING TUBE AND FIN HEAT EXCHANGER WITH REDUCED TUBE DIAMETER, AND PRODUCT PRODUCED THEREBY

According to a preferred embodiment, an improved method and apparatus for manufacturing tube and fin heat exchangers that includes a step for reducing the outer diameter of stock tubing to a value well below nominal prior to bending the tubing into hairpins. The reduced diameter increases the stiffn...

Beschreibung
Zusammenfassung:	According to a preferred embodiment, an improved method and apparatus for manufacturing tube and fin heat exchangers that includes a step for reducing the outer diameter of stock tubing to a value well below nominal prior to bending the tubing into hairpins. The reduced diameter increases the stiffness of the resultant hairpins and allows for efficient lacing of the heat exchanger fins and end plates. The method uses pre-size rollers that are adjustable for reducing the diameter of the tubing. The invention also includes a hairpin and heat exchanger manufactured according to the method. De acuerdo con una modalidad preferida, un método y aparato mejorado para fabricar tubo e intercambiadores de calor entre aletas que incluye una etapa de reducción de diámetro exterior de tubería de reserva a valor muy bajo del valor nominal para unir la tubería en horquillas. El diámetro reducido incrementa la resistencia de las horquillas resultantes y permite la unión eficiente de aletas de intercambiador de calor y placas finales. El método utiliza rodillos pre-medidos que son ajustables para reducir el diámetro de la tubería. La invención también incluye una horquilla y intercambiador de calor fabricado de acuerdo con el método.
