Abstract
A heat exchanger of the type having a tube assembly made up of a number of tubes through which a first medium flows and around and between which a second medium flows to accept heat from, or transfer heat to, the first medium. One of the media is constrained by a baffle to follow a path through the heat exchanger. According to the invention, the baffle is completely separate from the tubes, so permitting the baffle to adjust automatically. The baffle may be carried on springs and the position based on a pressure balance of the first medium, with the result of allowing the first medium to flow through a varying amount of tubes.
Claims7
A heat exchanger for transferring heat from a liquid comprising:
- a first header tank;
- a second header tank;
- a plurality of tubes fluidly joining the first header tank and the second header tank,
- a moveable baffle which is provided within the first header tank, dividing the first header tank into a first chamber and a second chamber;
- and
- a plurality of track rails disposed inside the first header tank that guides the moveable baffle, wherein the moveable baffle position changes a quantity of the plurality of tubes in fluid communication with the first chamber and second chamber.
