(57) The invention relates to a heat exchanger, comprising:
- a casing, comprising:
- a substantially U-shaped body as seen in cross-section and extending in a longitudinal
direction, wherein a base of the U-shape body comprises a gas outlet opening and wherein
an open end, opposite to the base, of the U-shape body comprises a receiving space
for receiving a burner, and
- two end plates arranged at the two longitudinal end zones of said U-shape body;
- a plurality of pipes arranged within said casing and connected to said end plates,
through which pipes in use a liquid can flow;
- a plurality of connecting means for providing a liquid through flow connection between
at least two pipes at each longitudinal end zone of said U-shape body, such that liquid
flowing through a first pipe of the at least two pipes is directed to the other pipe
of the at least two pipes,
wherein a first part of the pipes is arranged in a first pattern defining two legs
of a substantially U-shape as seen in cross-section, said first pattern being arranged
substantially parallel to legs of said U-shape body, and
wherein a second part of said pipes are arranged within a space at least partly bounded
by said first pattern.
The invention further relates to an assembly of a heat exchanger according to the
invention and a burner, wherein the burner is arranged in said receiving space.
