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.

Abstract: A plate cooler for fluids, in particular hydraulic oil, having a parallelepiped packet of spaced-apart plate elements (1), which include vertical fluid channels (2) and air channels (3) disposed between the fluid channels and which at their ends communicate with a distributor box (4) disposed at their upper boundary and with a collection box (4?) disposed at their lower boundary, wherein the distributor box (4) can be made to communicate with at least one feed line leading away, and the collection box (4?) can be made to communicate with at least one discharge line leading away, and both boxes (4, 4?) are each embodied as a hollow extruded profile section of aluminum having a horizontal fluid channel (5) and have guide grooves (6), open toward the outside and T-shaped in cross section, for attaching connecting elements, and wherein the distributor box (4) and the collection box (4?) are closed off on both ends and have at least one upward- and downward-pointing horizontal opening (7) each, at which a respecti

Abstract: An oil cooler, in particular for hydraulic oil, which is composed of spaced-apart cooling plates which are in the form of a parallelepiped-shaped package (1), said plates separating coolant channels and oil channels from each other. Connections (3, 4) for supplying and removing the oil and the coolant are provided on the front side (2) of the plate package, and filter plates (4) are arranged upstream from the plate package on the other side (5) of the plate package. The measurements of the filter plates essentially correspond to the measurements of the cooling plates. The filter plates are detachably connected to the plate package via a closing face plate (1?). The filter plates are transversed by oil openings, which are connected to the oil inlet opening (2?) in the closing face plate and to an oil inlet opening (2?) in the plate package.

Abstract: A plate cooler for fluids, in particular hydraulic oil, having a parallelepiped-shaped package of plate bodies forming spaced-apart fluid channels, the air channels being interposed between adjacent plate bodies and the plate bodies communicate on their ends with fluid channels in a distributor box and a collection box, which are provided with inlet and outlet lines. The distributor box and the collection box are each embodied as an extruded aluminum profile and include a continuous channel, forming the fluid channel, and a ribbed body, which has lateral ribs with continuous guide grooves for mounting elements and receiving slots for the extruded plate body profile. The fluid channels formed by the plate bodies, via the receiving slots, discharge into a collection chamber, communicating with the continuous channel, of the ribbed body, which is in communication with the continuous channel.

Abstract: The invention relates to an adapter bit (6) for the parallelepiped liquid distributing section (2) of a liquid treatment device (1) which is provided in a corner area with a flattened section (3) on which the adapter bit (6) can be placed. The adapter bit (6) has a base (6?) with a liquid passage (7) corresponding to the liquid passage (4) of the flattened section (3), and a pipe conduit connection (10) which is configured as a universal connector. A base section (6?) of the adapter bit comprises a seat (11) for a temperature sensor (12) which sensor is embedded into the seat by means of a casting compound (13). A connecting cable (14) leading away from the base section (6?) comprises an electrical connector (15) via which the temperature sensor (12) is connected to a temperature control device.

Abstract: Disclosed is a heat exchanger for fluids, particularly hydraulic oil, comprising a housing (1) in which fluid ducts (4) and coolant ducts (5) alternate and which is equipped with an inlet (8) for hot fluid, an outlet for cooled fluid as well as an inlet and an outlet (10) for the coolant. An internal cylinder chamber (7) that is lined by a fluid filter (13) on the circumference thereof is provided inside the housing. The delivered hot fluid or the discharged cooled fluid is fed into or discharged from the fluid ducts via said fluid filter (13).

Abstract: A plate cooler for cooling a fluid made of a plurality of superposed pairs of spaced plates sealed at their margins by side and end plates to form fluid flow channels and connected by lateral plates. The spaced plates and lateral plates are provided with aligned fluid flow openings forming a fluid flow conduit connected to a fluid input and output. The cooler is preferably made of aluminum or an aluminum alloy and is assembled by vacuum welding.
