Accumulator for a cooling fluid and heat exchanger

An accumulator for a cooling fluid, the accumulator comprising:

• a floor having a length and a width that is perpendicular to the length, the width being shorter than the length, the floor having a first side and a second side extending in a length direction of the floor, the first side being on an opposite side from the second side, the floor having an interface on the first side for connecting a chamber of the accumulator to a plurality of cooling tubes and to an opening on the second side wall that extends at least over a partial area of the chamber, the interface including at least two first interfaces and at least two second interfaces that are disposed along a same linear plane in the length direction of the floor;
• and
• a lid that is configured to seal the opening on the second side of the floor in a fluid-tight manner, the lid having straight sections, a projection and two diametrically opposed sealing sections, the straight sections extending in a length direction of the floor, the projection being integrally connected to and disposed between the straight sections and extending from the second side through the first side of the floor in a width direction of the floor and between the at least two first interfaces and the at least two second interfaces, the two diametrically opposed sealing sections extending from opposite ends of the straight sections in the width direction of the floor, each diametrically opposed sealing section having a first bent section that bends the end of the corresponding straight section in the width direction of the floor and a second bent section that bends the end of the corresponding straight section in the length direction of the floor, the ends of the straight sections extending from the respective second bent section in a direction opposite from each other,
• wherein the floor has at least one groove that is configured to guide the first and second bend sections of the lid,
• wherein the projection includes a pair of straight parts that extends from the second side through the first side of the floor in a width direction of the floor, the straight parts are parallel to each other with a space therebetween,
• a plane that extends through the straight parts of the projection extends parallel to the linear plane of the floor, and
• the straight sections of the lid are spaced away by the space.
