HYDRAULIC FLUID COOLER AND FILTER

摘要

One aspect of the invention features a hydraulic fluid cooling and filtering assembly including an inlet tank with an assembly inlet, an outlet with an assembly outlet, and a heat exchanger with multiple fluid channels where channel outlets are spaced apart along a length of the outlet tank over a flow outlet span and cross-flow air channels are formed between the fluid channels. A filter element disposed within the outlet tank includes an internal cavity in communication with the assembly outlet and porous filtering material separating the internal cavity from the heat exchanger channel outlets. The filter element is elongated and has an outer filtering surface extending along at least most of the flow outlet span of the heat exchanger; such that straight lines are defined by the respective inlets and outlets of each fluid channel that intersect the outer filtering surface which is exposed to the fluid channel outlets.

1. A hydraulic fluid cooling and filtering assembly (102) comprising:
an inlet tank (12) in hydraulic communication with an assembly inlet (18); an outlet tank (14) in hydraulic communication with an assembly outlet (20); a heat exchanger (16) defining:
multiple fluid channels (22) forming separate flow paths between respective fluid channel inlets (23) at the inlet tank and respective fluid channel outlets (24) at the outlet tank, the fluid channel outlets spaced apart along a length of the outlet tank over a flow outlet span (48), andcross-flow air channels (26) between the fluid channels; and a filter element (36) disposed within the outlet tank (14), the filter element defining an internal cavity (40) in hydraulic communication with the assembly outlet (20) and comprising porous filtering material (38) separating the internal cavity from the heat exchanger fluid channel outlets, wherein the filter element (36) is elongated and has an outer filtering surface extending along at least most of the flow outlet span (48) of the heat exchanger (16), and wherein the outer filtering surface is directly exposed to the fluid channel outlets (24) such that straight lines (49) defined by the respective inlets (23) and outlets (24) of fluid channels (22) of the heat exchanger (16) intersect the outer filtering surface, passing only through fluid within the outlet tank.
