  • Tube and tube-plate assembly with soft joints
    Patent number: 4159035
    Abstract: Tube passages slightly bigger than the tubes are formed in a plate. A soft resilient sheet is placed on one side of the plate. The tube is forcibly inserted in the tube passages and draws a portion of the sheet which is then cut. In the assembly the sheet, which has a bigger thickness than the interval between the tube and the tube passage, forms a flange beyond the tube plate.
    Type: Grant

  • Device for fixing tube plates and lateral flanges of heat exchangers
    Patent number: 3960210
    Abstract: The flanges of the heat-exchanger comprise at two ends thereof lugs or connecting members delimiting a transverse fold extended by a tongue up to the tube plates. The ends of the tubes are positioned in the tube plates and the tongue is fixed to the tube plate. The assembled heat exchanger is then submitted to brazing.

  • Brazing jig for aluminum radiator cores
    Patent number: 3941293
    Abstract: The process is characterized in that hot gas are blown at right angle with the front face of the parts to be brazed into the contiguous areas of an enclosure. The speed of the hot gas in a first area is regulated in order to ensure pre-heating, the speed in a second area is regulated in order to increase the temperature to the brazing temperature and the speed in a third area is regulated in order to ensure at least a partial cooling of the parts before they are withdrawn from the enclosure.

  • Method for equalizing differential heat expansions produced upon operation of a heat exchanger and heat exchanger embodying said method
    Patent number: 3939908
    Abstract: Radiator comprising tubes, tube plates fitting ends of said tubes, lateral flanges and corrugated fins inserted between the tubes and between the tubes and the flanges. A bearing area is designed along the flanges or the tubes close to the tube plate for applying end fins between the flange and the adjacent tube. Means are designed for at least limiting joining portions of said fins extending at the level of said area.
