<p>Heat exchanger comprising: a group of parallel metal pipes (2), located at mutual distance through which a first heat exchanging medium can flow, which pipes can be placed into heat exchanging contact with a second heat exchanging medium via their outer surfaces; positioning means (4, 5) for holding these pipes in a mutual position; and supporting means (11, 12) for supporting the group of pipes and the positioning means. The heat exchanger according to the invention has for this purpose the feature that the supporting means comprise: at least one first plate (11, 12), with holes for passage of the pipes with clearance; a second plate (4, 5), which co-acts with this first plate and which is fixedly coupled to the group of pipes; at least one pin (10), extending in longitudinal direction of the pipes (2) and connected to one of the plate (11, 12), which pin (10) is slidable in a hole (8) arranged in the other plate (4, 5) such that when changes occur in the length of the pipes (2) as a result of temperature changes, the relative axial position of the two plates (4, 5) can vary.</p> |
