The present invention discloses a heat exchanger for exchanging heat between a first fluid and a second fluid. The heat exchanger comprises a plurality of heat exchange tubes fluidically connecting a first manifold and a second manifold for a first fluid flow there between. The first fluid flows between the manifolds through the tubes and a second fluid flows around the heat exchange tubes. At least one heater module disposed between two of the heat exchange tubes and in contact with the second fluid. One or more electrical terminals of the heater module is adapted to protrude outward from at least one of the manifolds.

The present invention relates about a wiper system for cleaning a vehicle window, comprising a drive attachment (2), an arm (8), a wiper blade (10) and a connecting body (12) located between the drive attachment (2) and the arm (8), the wiper system (1) comprising a pivot link (P) between the connecting body (12) and the drive attachment (2), the wiper system (1) comprising a rotational link (A) between the connecting body (12) and the arm (8), the rotational link (A) having an axis that extends along a first direction (F), the pivot link (P) having an axis that extends along a second direction (S), said first direction (F) and said second direction (S) being intersected, wherein the wiper system (1) comprises a mechanical link (14) between the drive attachment (2) and the arm (8) enforcing a rotation of the pivot link (P) around the second direction (S) upon a rotation of the arm (8) around the first direction (F).

A flat tube assembly 1 for a heat exchanger, comprising a flat tube 10 and a fin 20 placed inside the tube 10, the flat tube 10 being formed by a sheet material and being defined by a bottom wall 11, a top wall 12 and two side walls 13, the distance between the bottom wall 11 and the top wall 12 defining the height direction H with tube height Ht, and the distance between the side walls 13 defining the width direction W, wherein at least one of the side walls 13 and a corner section 14 between the bottom wall 11 and this side wall 13 are formed by layers of the sheet material, and wherein the fin 20 is a corrugated sheet with plurality of adjacent walls joined at top and bottom bent portions 22 which are in contact with the top and bottom walls 11, 12 of the tube 10 respectively, the adjacent bent portions 22 being distanced from each other by substantially constant distance T1, wherein a terminal adjacent wall 21 of the fin 10 has a bottom side edge 23 which is distanced from the adjacent bottom bent portion 22, along the width direction W, by a distance T2 which is bigger than distance T1, and is distanced from the top wall 12, along the height direction H, by a distance Hf which is smaller than Ht.

A manifold (1), in particular for use in a cooler (19) of a cooling system, comprises a housing (4), which is a unitary element having a closed profile and has at least one longitudinal channel (5) defined therein and also a plurality of slots (10) on one of surfaces of the housing (4), which slots (10) are in fluid communication with the longitudinal channel (5). The manifold (1) further comprises a covering profile (2) applied on the housing (4), having a plurality of slots (3) at positions corresponding to the positions of the slots (10) of the housing (4) and fixedly connected to the housing (4). The slots (3, 10) of both components of the manifold (1) are adapted for receiving tubes (17) of the cooler (19), while the longitudinal channel (5) has on its surface (6) a stopping means (8) against which the tubes (17) of the cooler (19) may abut.
