A laundry dryer including: - a casing rotatably supporting a drum for receiving a load to be dried, said drum being apt to rotate around a drum axis, said casing including ∘ a rear wall and a front wall defining, respectively, a rear side and a front side of said casing, an aperture being realized on said front wall to access said drum; ∘ a basement defining a basement plane (X,Y); - A process air conduit in fluid communication with the drum where a process air stream is apt to flow, said process air conduit including a drum exhaust process air conduit having an inlet in which process air exiting said drum is conveyed; - A heat pump having a heat pump circuit in which a refrigerant can flow, said heat pump circuit including a first heat exchanger where the refrigerant is cooled off and the process air is heated up, and a second heat exchanger where the refrigerant is heated up and the process air is cooled off; said first and/or second heat exchanger (31, 32) being arranged in the process air conduit in order to perform heat exchange between said refrigerant flowing in said heat pump circuit and said process air; Wherein - Said drum exhaust process air conduit includes an inlet edge surrounding said inlet and defining a front end and a rear end; - A first portion of said second heat exchanger is located below said rear end of said inlet edge and a second portion of said second heat exchanger is located below said drum; - A filter to filter process air arranged at the inlet of said drum exhaust process air conduit in such a way that an air flow streaming through said drum enters said drum exhaust process air conduit passing through said filter, said filter having an inner abutment surface and an outer abutment surface, said inner abutment surface being the surface more distant from said front wall than the outer abutment surface, said inner and outer abutment surfaces being in abutment with a first and a second edge portions (17a, 17b), respectively, of said inlet edge; - Wherein said second heat exchanger is located downstream said filter in the direction of flow of said process air in said process air conduit; and - wherein said first portion of said second heat exchanger is located below said inner abutment surface; and - wherein said drum exhaust process air conduit includes a first portion having a substantially vertical component and a second portion having a longer horizontal component, so that said process air passes through said filter in a substantially vertical direction and through said second heat exchanger in a substantially horizontal direction. - a casing rotatably supporting a drum for receiving a load to be dried, said drum being apt to rotate around a drum axis, said casing including ∘ a rear wall and a front wall defining, respectively, a rear side and a front side of said casing, an aperture being realized on said front wall to access said drum;
