Abstract: A plate cooler for fluids, such as hydraulic oil, having a parallelepiped-shaped package of plate bodies forming spaced-apart fluid channels and air channels interposed between adjacent plate bodies. The plate bodies communicate on their ends with a fluid channel in a distributor box and a collection box. The distributor and collection boxes have an extruded aluminum profile, a continuous fluid channel, and a ribbed body having lateral ribs with continuous guide grooves for mounting elements and receiving slots for the extruded plate body profile. The fluid channels discharge into a collection chamber, communicating with the continuous fluid channel of the ribbed body. The continuous receiving slots for the plate bodies in the distributor box and in the collection box are configured in circular and conical form, and the inserted plate bodies are connected thereto in fluid-tight fashion in a low-temperature adhesive bonding process.

Abstract: An adapter cap for the parallelepiped distributor section of a liquid treatment arrangement, which is provided with a flattened section in a corner area, on which the adapter cap can be placed, wherein the adapter cap has a base with a passage for a liquid, which corresponds to the passage for the liquid in the flattened section, and a pipe line connection. The pipe line connection comprises a universal connector, and a receptacle for a temperature sensor, which has been totally embedded into the receptacle by a casting compound, is provided in a base section of the adapter cap, where a connecting cable with an electrical plug connector leading away from the base section is provided, by which the temperature sensor is connectable to a temperature regulating arrangement.
