Definitions

  • This invention relates to an oil cooler for cooling engine oil circulating in a water-cooled engine, by exchanging heat between cooling water for the water-cooled engine and the engine oil.
  • An object of the present invention is to provide an automotive oil cooler with a small size.
  • an oil cooler has a tube disposed in a cooling water passage and defining an oil passage therein, an oil side fin fixed to an inside wall of the tube, and a water side fin fixed to an outside wall of the tube and having a plate thickness thicker than that of the oil side fin.
  • the oil side and water side fins are corrugated fins. Accordingly, the oil side and water side fins can be formed to have small fin pitches, respectively, so that the size of the oil cooler is reduced. Further, each of the fins can have a high density and a large withstand pressure strength.
  • the plate thickness of the water side fin is thicker than that of the oil side fin, a climbing rate of temperature of the water side fin is prevented from exceeding that of the oil side fin when they are brazed. As a result, brazing deficiencies caused by erosion of the water side fin can be prevented.
  • the oil cooler further has a casing, a partition member integrally brazed to the casing and partitioning inside of the casing into the cooing water passage and a filter casing portion, and a filter disposed in the filter casing portion. Accordingly, there is no need to use O-rings for securing sealing property between the cooling water passage and the filter casing portion, resulting in decrease in number of parts for the oil cooler. This further results in manufacturing cost reduction of the oil cooler.
  • An oil cooler 100 shown in FIG. 1 of a first preferred embodiment is to be fixed to a wall of a water-cooled engine (herebelow referred to as an engine).
  • the oil cooler 100 has a cylindrical filter element 101 (herebelow referred to as a filter) for filtering engine oil (herebelow referred to as oil) circulating in the engine so that foreign materials are removed from the oil.
  • the oil cooler 100 further has an oil cooler core portion 102 (herebelow referred to as a core portion) for exchanging heat between engine cooling water (herebelow referred to as cooling water) and the oil.
  • the core portion 102 is composed of a plurality of core units which are laminated with and brazed to one another in a thickness direction thereof (see FIG. 2).
  • Each of the core units has core plates 102a, 102b which are pressed to have specific shapes and a rectangular corrugated oil side inner fin 102c which is brazed to the core plates 102a, 102b therebetween.
  • a cooling water passage 103c for flowing the cooling water therein and an oil passage (tube) 103d for flowing the oil therein are separated from one another by the core plates 102a, 102b. That is, the oil passage 103d defined by the core plates 102a, 102b is provided in the cooling water passage 103c.
  • Each of the core units is laminated with adjacent one of the core units through a rectangular corrugated cooling water side inner fin 102d.
  • the cooling water side inner fin 102d is brazed to the corresponding core plates 102a, 102b between the two adjacent core units.
  • the thickness (fin thickness, plate thickness) Tw of the cooling water side inner fin 102d is thicker than the thickness (fin thickness, plate thickness) To of the oil side inner fin 102c.
  • each of the inner fins 102c, 102d has as shown in FIG. 3 well-known louvers 103e which are formed by partially cutting and integrally bending up the inner fins 102c, 102d on the both surfaces thereof.
  • the cooling water and the oil meander on the both surfaces of the respective inner fines 102c, 102d due to the louvers 103e.
  • the core portion 102 is disposed in a filter bracket (casing) 105 composed of a bracket member 104 for being fixed to the engine and a partition member 103 brazed to the bracket member 104.
  • the bracket member 104 and the partition member 103 are made of metal, specifically aluminum in this embodiment.
  • the partition member 103 partitions inside the bracket member 104 into a core space 103a in which the core portion 102 is held and a filter casing portion (filter space) 103b in which the filter 101 is held.
  • the core space 103a accommodates the core portion 102 and constitutes part of the cooling water passage 103c.
  • the core portion 102 is brazed to the inner wall of the filter bracket 105 (the partition member 103 and the bracket member 104).
  • the filter bracket 105 has an inlet portion 102e for allowing the cooling water to flow into the core space 103a and an outlet portion 102f for allowing the cooling water, which has finished to exchange heat, to flow out from the core space 103a.
  • Connection pipes 102g are connected to the inlet and outlet portions 102e, 102f by brazing for connecting external pipes (not shown).
  • each of the core plates 102a, 102b, the inner fines 102c, 102d respectively having front and back surfaces covered with brazing filler metal, and the partition member 103 are laminated with one another in a specific order in the filter bracket 105, and are brazed to one another in a state where an engine installation face 104a of the bracket member 104 is set on a lower side.
  • the bracket member 104 is fixed to the engine through the engine installation face 104a. Accordingly, the core portion 102 can be securely brazed due to a gravitational force thereof.
  • a check valve 106 made of rubber is provided to prevent the oil, which enters the filter casing portion 103b through the core portion 102, from flowing back toward the core portion side.
  • the oil is filtered by the filter 101 and is returned toward the engine through a pipe portion 107 which extends from the central portion of the filter 101 and penetrates the central portion of the core portion 102.
  • a seal member 108 made of rubber is disposed between the pipe portion 107 and the filter 101 to seal the gap between the pipe portion 107 and the filter 101.
  • the filter 101 is pushed against the partition member 103 by an elastic member 109 such as a disc spring, and the elastic member 109 is pushed by a lid 110 covering the opening of the filter casing portion 103b.
  • the lid 110 is screwed to the bracket member 104 through an O-ring 111 to hermetically seal the filter casing portion 103b.
  • the lid 110 has a bolt hole 104b for receiving a bolt (not shown) that fixes the filter bracket 105 (bracket member 104) to the engine.
  • the bolt hole 104b is formed with width across flats to engage with a tool such as a spanner, which is used to rotate the lid 110.
  • the lid 110 is detached from the bracket member 104 when the filter 101 is exchanged.
  • the inner fins 102c, 102d are formed into rectangular corrugated shapes, respectively, by a roller forming method as a corrugated fin for a heat exchanger such as a radiator or a condenser can be. Because of this, the inner fins 102c, 102d can have a fin pitch (see FIG. 3) smaller than that of an offset type fin that is formed by pressing. As a result, a withstand pressure strength (mechanical strength) of the tube (oil passage) 103d becomes large, and the density of the inner fins is increased so that the oil cooler 100 is miniaturized.
  • a conventional automotive oil cooler has, as disclosed in JP-B2-2-10357, a cooling water passage, an oil passage (tube) defined within the cooling water passage by core plates, and offset type fins brazed to both surfaces (in both passages) of each of the core plates.
  • the inventors of the present invention first studied the offset type fins and tried to decrease the fin pitch and the height of the offset type fins so that the fins have high densities.
  • the fin pitch and the height of the inner fins 102c, 102d can be readily controlled.
  • the engine oil circulates within the engine to lubricate movement of pistons, com shafts, and the like and to cool such parts.
  • the increase in density of the inner fins can decrease pressure loss of the oil cooler.
  • the engine oil may not be supplied to all over the engine and accordingly the engine may seize.
  • the thickness To of the oil side inner fin 102c is decreased to prevent pressure loss from increasing within the tube 103d, without lowering the withstand pressure strength of the tube 103d.
  • the oil cooler 100 can be miniaturized without deteriorating qualities such as the brazing properties and the withstand pressure strength.
  • the water side inner fin 102d because the water side inner fin 102d always contacts the cooling water, the water side inner fin 102d is eroded more easily than the oil side inner fin 102c. Therefore, if the thicknesses of the inner fins 102c, 102d are equal to one another, the water side inner fin 102d is eroded more quickly than the oil side inner fin 102c. That is, the life-time of the oil cooler 100 is restricted by the life-time of the water side inner fin 102d.
  • the thickness Tw of the water side inner fin 102d is thicker than the thickness To of the oil side inner fin 102c, the life-time of the water side inner fin 102d is lengthened, and consequently the life-time of the oil cooler 100 is lengthened.
  • the thickness Tw of the water side inner fin 102d is more than 1.05 times as thick as the thickness To of the oil side inner fin 102c. More preferably, the thickness Tw of the water side inner fin 102d is more than 1.10 times as thick as the thickness To of the oil side inner fin 102c.
  • the fin height ho of is preferably in a range of 1 mm to 3 mm
  • the thickness To is preferably in a range of 0.05 mm to 0.3 mm
  • the fin pitch fpo is preferably equal to or smaller than 4 mm.
  • the plate thickness Tp of the tube 103 (core plate 102a or 102b) is preferably equal to or larger than 0.2 mm.
  • the fin height hw is preferably in a range of 1mm to 3 mm
  • the plate thickness Tw is preferably in a range of 0.05 mm to 0.3 mm
  • the fin pitch fpw is preferably equal to or smaller than 4 mm.
  • FIGS. 4 through 9 show a relationship between an oil side heat transfer coefficient ⁇ 0 and the height ho or ht of the inner fin 102c or 102d, when the thicknesses To, Tw of the inner fins 102c, 102d are 0.1 mm, respectively, and the thickness Tp of the tube 103d is 0.6 mm.
  • the lower limit (0.05 mm) of the thickness To, Tw of the inner fins 102c, 102d is determined so that the inner fins 102c, 102d can be securely brazed.
  • the core space 103a is filled with the cooling water, and the filter casing portion 103b is filled with the oil. Because the partition member 103 and the bracket member 104 are unified by brazing, it is not necessary that several O-rings are intervened between the core space 103a and the filer casing portion 103d to secure the sealing property therebetween as for example described in European Patent No. 631804A1 (January 4, 1995). This results in decrease in number of the parts of the oil cooler 100, and therefore results in manufacturing cost reduction and size reduction of the oil cooler 100. The mountability of the oil cooler 100 to the vehicle is improved due to the size reduction. In addition, the number of the O-rings that are consumable supplies is decreased, so that a burden to a user of the oil cooler is reduced after the user has purchased the oil cooler.
  • an oil cooler 400 in a second preferred embodiment has around the filter 101 a cooling water passage 401 in which the cooling water flows.
  • the cooling water passage 401 is provided between a partition member 1031 and the bracket member 104. Accordingly, an amount of heat exchange between the cooling water and the oil is increased, so that the temperature of the oil can be more decreased. This lengthens the life-time of the oil. Accordingly, the frequency for exchanging the oil is decreased so that the burden of the user is reduced.
  • both of the inner fins 102c, 102d are formed into a rectangular corrugated shape, respectively.
  • the shape of the fins are not limited to that and may be a sinwave like shape.
  • the oil cooler 100 or 400 is an exterior type oil cooler having the core portion 102 disposed outside of the engine, the present invention can be applied to an interior type oil cooler having a core portion disposed in an engine water jacket (cooling water passage) within the engine.
  • the bracket member 104 of the filter bracket 105 has the filter casing portion 103b.
  • a filter casing 201 for accommodating the filter 101 therein is integrated with the filter 101.
  • the filter casing 102 is also exchanged together with the filter 101.
  • the partition member 103 separates the core space 103a from the portion where the filter 101 and the filter casing 201 are disposed, and simultaneously serves as a fixing member for fixing the filter 101 and the filter casing 201.
  • the partition member 103 is composed of an aluminum plate.
  • an oil cooler 300 of a fourth preferred embodiment has a partition member 1032, which is a honeycomb structural member (see FIG. 13) composed of an aluminum thin plate 1032c perpendicularly joined to two aluminum thin plates 1032a, 1032b therebetween. Accordingly, the partition member 1032 is lightened, resulting in lightening of the oil cooler 300. In addition, the rigidity of the partition member 1032 is improved.
  • the other features and effects are the same as those in the third embodiment.
  • An oil cooler 500 in a fifth preferred embodiment is a modified one of the oil cooler 400 in the second embodiment.
  • the oil cooler 500 has a spiral first fin (first protruding member) 501 in the cooling water passage 401.
  • the spiral fin 501 protrudes from the partition member 1031 toward the bracket member 104 in the cooling water passage 401. Accordingly, the heat exchange between the cooling water and the oil is facilitated in the cooling water passage 401, so that the temperature of the oil is further lowered.
  • the other features and effects are the same as those in the second embodiment.
  • An oil cooler 600 in a sixth preferred embodiment is another modified one of the oil cooler 400 in the second embodiment.
  • the oil cooler 600 has a second fin (second protruding member) 601 protruding from the outside wall of the bracket member 104 of the filter bracket 105.
  • This embodiment is explained based on the oil cooler 400 in the second embodiment; however, it may be applied not only to the oil cooler 400 but also to the oil cooler 500 in the fifth embodiment, or the oil cooler in which the cooing water passage 401 is not provided as in the first to third embodiments.
