A heat exchanger assembly includes a first heat exchange fluid conduit and at least one fin. The first heat exchange fluid conduit defines a passageway therethrough and is configured to receive a flow of a first heat exchange fluid. At least one fin is disposed to receive a flow of a second heat exchange fluid. The fin(s) is/are coupled to the heat exchange fluid conduit at an interface that is configured to reduce accumulation of debris entrained in the second heat exchange fluid.

Heat exchanger with improved plugging resistance

A tool coupler comprises a coupler frame and an attachment frame. The attachment frame is provided with two hooks that engage two catches located on the coupler frame. The coupler frame is provided with two locking pins and the attachment frame is provided with two receiving apertures, for locking the coupler frame to the attachment frame. Both locking pins are actuated by a double acting hydraulic cylinder. The hydraulic cylinder is slidably mounted on the coupler frame. The hydraulic cylinder is provided with a barrel end having the first locking pin and a piston rod having the second locking pin. The coupler frame and the hydraulic cylinder are provided with limiters which limit the sliding movement the piston rod and the barrel end relative to the coupler frame.
