FIELD: heating.SUBSTANCE: invention relates to the heat-exchanger (102) of plate type comprising: heat exchange assembly (104); end panels (106) and connecting elements (107) of end panels used for the end panels (106) connection. The heat exchange assembly (104) comprises a set of heat exchange plates (112) and pair of external heat exchange plates (114) installed from opposite sides of the heat exchange assembly (104). At least one external heat exchange plate (114) is mechanically connected to the adjacent end panel (106) and contains part (122) of main external surface looking towards the adjacent end panel (106) connected in terms of the heat to the contact area (125) of the adjacent end panel (106). The thermal expansion in plane of the part (122) of the main external surface is similar to the thermal expansion in plane of the contact area (125) of the end panel.EFFECT: improved design.15 cl, 9 dwg |
