Definitions
- the present invention relates to a plate cooler for liquids, in particular hydraulic oil, with a parallelepipedic package consisting of spaced plates forming liquid channels, air lamellas being interposed between adjacent liquid channels and the liquid channels being connected at the end to liquid distribution channels in distribution boxes which are connected to supply lines. and derivatives are provided.
- the distribution boxes provided at the ends of the liquid channels, which are provided with the liquid connections are additionally bridged by a bypass pipeline which runs outside the cooler and allows a flow when the oil is cold.
- This version is structurally complex and increases the space required for the radiator installation.
- the invention aims to avoid these deficiencies and to provide a plate cooler of the type mentioned in the introduction, which can be constructed and connected in a structurally simple manner and which enables a bypass flow in the cold state without an external pipeline.
- the plate cooler according to the invention is distinguished by the fact that in the package, bypass channels run parallel to the liquid channels between the distributor boxes and the distributor box provided on the liquid inlet side is equipped in the area of the bypass channels with a valve which connects the connection between the distribution channel and the bypass channels in the
- the valve closure body is biased into the closed position by a spring, preferably up to a pressure difference of 2-3 bar (opening pressure).
- a spring preferably up to a pressure difference of 2-3 bar (opening pressure).
- the invention advantageously enables that in normal operation, when the oil is warm and the pressure loss across the liquid channels is small ( ⁇ 2 bar), the bypass is closed and the entire amount of oil flows through the liquid channels. If the pressure loss in the liquid channels is> 2-3 bar in cold operation, the bypass valve opens and enables the direct connection between the distribution channels via the bypass channels.
- the plate cooler for liquids in particular hydraulic oil, formed from aluminum or an aluminum alloy, has a parallelepipedic package 3, which is arranged between an end plate 1 and an end plate 2, and is composed of spaced plates 4, each with two spaced plates 4 and arranged in between separate side plates 5 and end plates 6 liquid channels 7.
- the liquid channels 7 are connected at the end to liquid distribution channels 8, 8 ', which lead to supply and discharge lines 14, 14', which are formed, for example, by corner connectors 9, 9 '.
- Air fins 10 are interposed between adjacent liquid channels 7.
- the other openings 11, 12 of the distribution channels are closed by plugs, not shown.
- the distributor channels 8, 8 ' are each formed in a distributor housing 13, 13'.
- a threaded seat 18 ' is formed in a partition 18 of the housing 13 for a closure valve 15, which in normal operation in the cold state of the oil sets the upper distributor channel 8 with bypass channels 16, so that the oil also through the flows parallel to the end plate 2 to the other distribution channel 8 'leading bypass channels 16.
- the valve 15 closes, so that the oil only flows through the liquid channels 7 between the distributor channels 8, 8 '.
- the valve 15 is screwed into a receptacle of the partition 18 of the upper distribution box 13 with a holder 17 and the movable valve closure body 20 is biased into the closed position by a coil spring 19.
- the spring strength and spring constant is selected according to the desired pressure difference, which is preferably so large that a closed position of up to 2-3 bar opening pressure is made possible.
- the end plate 1, the end plate 2, the plates 4, the side plates 5, the end plates 6, the transverse plates 12 and the bypass channels 16 are made of coated aluminum or an aluminum alloy in the context of the invention and are welded to the package 3, whereby the Plate cooler withstands high mechanical and hydraulic loads, continuous loads and vibrations. It is understood that the described embodiment can be modified in various ways within the scope of the general inventive concept.
