1. A heat exchanger for a refrigerant fluid loop, the heat exchanger comprising:
at least one outlet configured to allow a refrigerant fluid to exit the heat exchanger;
a core;
a tank that comprises said at least one outlet;
at least one filter,
wherein the at least one filter is adapted to filter the refrigerant fluid that exits the tank and wherein said at least one filter is flat;
wherein the at least one filter comprises at least one frame and an elastic band, the elastic band being embedded around the at least one frame,
wherein the at least one filter comprises at least one flat mesh element configured to filter the refrigerant fluid, said at least one frame surrounding the at least one flat mesh element,
wherein the at least one flat mesh element is defined by a meshed surface and the at least one outlet of the tank is defined by an outlet surface, the meshed surface being bigger than the outlet surface; and
a connection pipe extending between a first intermediate block arranged at the outlet of the tank and a second intermediate block, said connection pipe integrating the at least one filter,
wherein the second intermediate block is brazed on the heat exchanger,
wherein the meshed surface is larger than a connection pipe surface,
wherein said connection pipe surface is delimited by a pipe calibre,
wherein said at least one filter is housed in a filtering chamber arranged so that the refrigerant fluid flows successively through a first portion of the connection pipe, then through the filtering chamber comprising the at least one filter and then through a second portion of the connection pipe.
