Abstract
A heat exchanger including a collecting tank and at least one flat tube row. The flat tubes have a discharge end secured to the collecting tank, a closed end, and a longitudinal separator dividing the tubes into oppositely-traversed channels, wherein at least a portion of one tube wall at the closed end and the separator associated with the tube wall portion are omitted. A closure piece closes the tubes where the tube wall portions are omitted. A partition in the collecting tank separates the inlet and outlet sides. Heat exchanger elements between the flat tubes are adapted to be traversed by a medium flowing outside the tubes. The first tube row may be connected with one end to one side of the collecting tank with a second tube row connected with its first end to another side of collecting tank.
Claims14
A heat exchanger, comprising:
- at least one collecting tank;
- at least one row of flat tubes having a first end secured to said collecting tank to discharge therein, a closed second end, and at least one longitudinal separator in said tubes dividing said tubes into oppositely-traversed channels, wherein at least a portion of one tube wall at said closed second end and the separator associated with said tube wall portion are omitted;
- at least one closure piece closing said tubes where said portions of said one tube wall are omitted;
- at least one partition in said collecting tank separating the inlet side from the outlet side;
- and
- heat exchanger elements arranged between said flat tubes and adapted to be traversed by a medium flowing outside of said flat tubes.
A heat exchanger, comprising:
- at least one collecting tank;
- at least two rows of flat tubes having a first end secured to said collecting tank to discharge therein, a closed second end, and at least one longitudinal separator in said tubes dividing said tubes into oppositely-traversed channels, wherein a first row of flat tubes is connected with one end to one side of the collecting tank and a second row of flat tubes is connected with its first end to another side of collecting tank;
- at least one partition in said collecting tank separating the inlet side from the outlet side;
- and
- heat exchanger elements arranged between said flat tubes and adapted to be traversed by a medium flowing outside of said flat tubes.
