Abstract
A heat exchanger comprises a main body and at least one header-held members, with the main body having a plurality of heat exchanging tubes whose both ends are connected to headers in fluid communication with them, wherein the header-held members are selected from a group consisting of a bracket and an external pipe-connecting member which are attached to the header. The header-held members each comprise a header-surrounding portion which is fitted sideways on and then brazed to the header while remaining self-retained on it, whereby the header-held member can be easily and rigidly secured to the header.
Claims14
A heat exchanger comprising:
- a first header;
- a second header spaced a predetermined distance from the first header and extending in parallel with the first header;
- a plurality of flat tubes each having both ends connected to the first and second headers in fluid connection therewith;
- fins each interposed between the adjacent flat tubes;
- a connecting member adjoined to at least one of the headers so as to connect an external piping to the header in fluid communication therewith;
- the connecting member comprising:
- a block-shaped joint body having a surface for flange-connection;
- a surrounding body integral with the block-shaped joint body and fittable sideways on the header;
- the surrounding body having a header-surrounding portion, an extension extending therefrom towards the tubes and contacting side surfaces thereof;
- wherein the header-surrounding portion covers slightly more than a semicircle of the header so that the connecting member remains self-retained on the header;
- and
- wherein the block-shaped joint body has a coolant-flow opening on the surface for flange-connection, and the header-surrounding portion has an inner curved surface in contact with the header and has a coolant-flow opening on the inner curved surface, with the openings being in fluid communication with one another by a coolant passage, and with the opening on the inner curved surface being aligned with an opening formed through a peripheral portion of the header.
