Abstract
A fluid to gas heat exchanger comprising a plurality of fin-tube elements (6). Each fin-tube element is an integral extrusion and comprises tubes portions (61) for carrying heat exchange fluid and fin portions (62) for dissipating heat. The fin portions and tube portions run in the same direction side by side.
Claims34
A fluid to gas heat exchanger comprising a plurality of fin-tube elements, each fin-tube element comprising at least one respective tube portion for carrying heat exchange fluid and at least one respective fin portion which is in contact with the tube portion and arranged for encouraging exchange of heat between fluid in the tube portion and the surroundings, wherein the respective tube portions and respective fin portions run side by side, the fin portions have a sinuous profile and the plurality of fin-tube elements are arranged relative to one another to define at least one respective sinuous airflow path therebetween for encouraging turbulent but free flowing airflow along said at least one respective sinuous airflow path.
A heat exchanger according to claim, 15 in which the antimicrobial agent is an antimicrobial substance in a silane.
A method of manufacturing a fluid to gas heat exchanger having at least one pair of headers and at least one fin-tube element which comprises at least one tube portion for carrying heat exchange fluid and at least one respective fin portion which is in contact with the tube portion and arranged for encouraging exchange of heat between fluid in the tube portion and the surroundings wherein the tube portion and fin portion run side by side, the fin portion has a sinuous profile and the fin-tube element is an extrusion with the tube portion and fin portion being integrally formed with one another, the method comprising the step of:
- connecting the at least one fin-tube element between the pair of headers so as to provide a fluid communication path between interiors of the headers via the tube portion.
A fin-tube element for a fluid to gas heat exchanger, the element comprising at least one tube portion for carrying heat exchange fluid and at least one respective fin portion which is in contact with the tube portion and arranged for encouraging exchange of heat between fluid in the tube portion and the surroundings, wherein the tube portion and fin portion run side by side the fin portion has a sinuous profile, and the fin-tube element is an extrusion with the tube portion and fin portion being integrally formed with one another.
A fluid to gas heat exchanger comprising at least one fin-tube element which comprises at least one tube portion for carrying heat exchange fluid and at least one respective fin portion which is in contact with the tube portion and arranged for encouraging exchange of heat between fluid in the tube portion and the surroundings, wherein the tube portion and fin portion run side by side and the fin portion has a smoothly varying sinuous profile.
A fluid to gas heat exchanger comprising a plurality of fin-tube elements, each fin-tube element comprising at least one respective tube portion for carrying heat exchange fluid and at least one respective fin portion which is in contact with the tube portion and arranged for encouraging exchange of heat between fluid in the tube portion and the surroundings, wherein the respective tube portions and respective fin portions run side by side, the fin portions have a sinuous profile and the plurality of fin-tube elements are arranged relative to one another to define at least one respective airflow path therebetween which comprises a series of throats to encourage turbulent air flow.
