<p>A header tank for a heat exchanger comprises a header plate (11) having openings (17) for the passage of a plurality of heat exchange tubes (5) and at least two end plates (7) on either side of the tubes (5), an elastic sealing means (13) arranged around the peripheral contour of the header plate (11), and a cover (15) having a cover base (25) which closes the header tank, thereby compressing the sealing means (13). The end plates (7, 107, 207) have, on the inside of the header plate (11, 111, 211), an axial extension of length (L′) greater than or equal to the height (h) of the sealing means (13, 113, 213). The sealing means (13, 113, 213) is arranged resting, under tension, against the end plates (7, 107, 207). The invention also relates to a heat exchanger comprising at least one such header tank, and to the method of assembling this heat exchanger.</p> |
