Definitions

  • the invention relates to a plate cooler for liquids, in particular hydraulic oil, with a parallelepipedi-see package of spaced, fluid channels forming plate bodies, between adjacent plate bodies air channels are interposed and the plate body end side with fluid channels in a distribution box and a collecting box in connection, the provided with liquid supply and -ableitonne.
  • bypass flow by bypass channels are provided in the package parallel to the liquid channels between the distribution box and the collecting box and provided on the liquid inlet side distribution box in the Bypass channels are equipped with a valve that allows the connection between the distribution channel and the bypass channels in the cold state. It is also known in a hydraulic oil air cooler to form the outgoing from the distribution box, opening into the collection box hydraulic oil lines through plate-shaped extruded hollow section.
  • extruded profiles are provided with integrally molded inner ribs.
  • the cooling surface for the hydraulic oil is increased and thus increases the cooling capacity.
  • the extruded profiles have a multi-chamber cross section.
  • the plate-shaped extruded profiles are soldered in the end of the known construction in openings of the distribution box and the collecting box, which, although an economical manufacturing process, but a soldering in the Va- Kuum or under inert gas (CAB) is required, which is relatively expensive.
  • CAB Va- Kuum or under inert gas
  • the invention aims to provide a plate cooler which can be easily manufactured and assembled from a few basic components in order to further reduce the production and manufacturing costs and to increase the versatility of the cooler.
  • the cooler according to the invention is characterized in that the distribution box and the collecting box are each formed as an aluminum extruded profile and provided with a passageway forming the liquid channel and a ribbed body, the lateral ribs with continuous guide grooves for mounting connection elements and receiving slots for the extrusion profile has, which open via the receiving slots in a communicating with the passage channel collecting space of the rib body, which communicates with the passage channel.
  • the receiving slots for the plate body in the distribution box and in the collecting box are circular-arc and conical and connected the inserted plate body with these preferably liquid-tight manner in a low-temperature process.
  • the one end of the distribution box and the collecting box is beveled to receive adapter bodies for piping connections.
  • FIG. 1 shows a view of a plate cooler according to the invention
  • FIG. 2 shows a left side view of the cooler according to FIG. 1
  • FIG. 3 shows a right side view of the cooler according to FIG. 1
  • FIG. 4 shows a detailed detail from FIG. 1 in an enlarged view

  • Fig. 8 is a section along the line VIII-VIII in Fig. 7
  • Fig. 9 10 is a sectional view along line XX in FIG. 9,
  • FIG. 11 is an analogous section to that of FIG.
  • FIG. 12 is a perspective view of a part of the cooler prior to assembly
  • FIGS. 13-18 show various adapter connections in partial perspective views.
  • the illustrated in Fig. 1 embodiment relates to a hydraulic oil cooler, which has a package of parallel plate bodies 1 and air channels 2 disposed therebetween air fins 2 ', which are flowed through in the example shown from top to bottom and end of a distribution box 3, starting in a collection box 3 'ends.
  • the distribution box 3 and the collecting box 3 ' are formed substantially the same.
  • the plate bodies 1 are formed as extruded aluminum profiles (eg, according to the patent AT 402 235) and held in through slots 5 of the junction box 3 and header box 3 ', as shown in FIG. 12, for example.
  • the rib body includes on opposite sides guide grooves 8 for receiving mounting elements, such as nuts 12 for (not shown) bolts for securing the radiator or the fan unit to a vehicle, a machine od. like.
  • the plate body 1 are each in an associated with the oil passage 6 communicating arched oil collecting space 3 'of the junction box 3 and the collecting tank 3 1.
  • the air fins 2' of a Distanzhait ceremonies each engage nose fins 3 '' of the distribution lerkastens 3 and the collecting box 3 '.
  • one end of the distributor box 3 or of the collecting box 3 ' is beveled, for example, at 45 ° in order to accommodate adapter bodies F shown in FIGS. 13-18 for pipe connections (not shown).
  • the other end is closed with a screw plug 9, as shown in FIG. 3.

  • the inserted into the receiving slots 5 plate body 1 can also be soldered to the slots. 1 and 5, the oil cooler is equipped with known bypass channels 10, wherein in the distribution box 3 via an end-side internal thread 13, a valve 11 is screwed (eg according to AT 414 042).
  • the valve closure body of the valve 11 may be biased by a spring in the closed position, preferably up to a pressure difference of 2-3 bar (opening pressure).
  • This embodiment advantageously allows that in normal operation, when the oil is warm and the pressure loss across the plate body 1 is small ( ⁇ 2 bar), the bypass is closed and the entire amount of oil flows over the plate body 1. If, in cold operation, the pressure loss in the plate bodies 1> 2-3 bar, the bypass valve 11 opens and allows the direct connection between the distribution box 3 and the collecting box 3 'via the bypass channels 10.
  • the adapter body F for pipe connections at the oblique front end of the junction box 3 and the collecting tank 3 ' can be fixed without complex welding with different orientation, whereby all in practice occurring connection conditions can be taken into account.

Abstract

La présente invention concerne un refroidisseur à plaques pour liquides, en particulier de l'huile hydraulique, comportant un ensemble parallélépipédique composé d'éléments en plaques (1) espacés, formant des canaux pour liquide. Des conduits d'air (2) sont intercalés entre les éléments en plaques contigus et les éléments en plaques sont, côté extrémité, en liaison avec des canaux pour liquide (6) dans une boîte de distribution et dans une boîte collectrice qui sont munies de conduites d'amenée et d'évacuation. La boîte de distribution (3) et la boîte collectrice (3') sont chacune réalisées sous forme de profilé en aluminium extrudé comportant un canal de passage formant le canal pour liquide et un élément nervuré (7) qui présente des fentes de logement (5) pour les éléments en plaques du profilé extrudé qui débouchent dans une chambre collectrice (3") en liaison avec le canal de passage, entre le canal pour liquide et l'extrémité frontale des éléments en plaques.
