Definitions

  • the present invention relates to heat exchanger assemblies, and, in particular, heat exchanger assemblies that function in high pressure and/or temperature environmental conditions.
  • JP2003314287 (A ) identifies use of cast Aluminum tanks which are welded to the heat exchanger core.
  • EP1524105 (A2, A3) identifies bonding of two material to form a structural part.
  • cast aluminum tanks means that such heat exchangers are required to have certain limitations, such as design limitations/need for complex features to provide for dimensional stability and/or part integration; additional manufacturing steps or operations to accomplish outcomes not possible using a casting aluminum process alone; higher costs due to these additional or secondary operations, welding necessary for tanks to the heat exchanger for assembly, high weight, and, in certain cases, inadequate corrosion resistance.
  • Heat exchangers have also used plastic tanks or manifolds ('tanks') to meet product requirements, For example, plastic charge air cooler tanks or tanks are used where the application temperature and pressure allow one to design them to meet the product requirements, Once specifications for temperature and pressure increase to a point where plastic tanks have limitations, cast aluminum tanks are often considered and used.
  • cast aluminum tanks there is some machining required which, as described above, leads to higher overall costs. Also, cast aluminum tanks can be designed with heavy wall sections and its characteristics mean that the types of part designs that can be implemented do not achieve the goal of reducing overall costs enough to make them as commercially desirable as wanted.
  • FIG 1 a tank is heat exchanger designed with cast aluminum Tank
  • Figure 1b shows the cast aluminum tank.
  • a heat exchanger capable of functioning in high temperature and/or pressure environments, with a lower profile cost for the same or better performance than aluminum cast tanks.
  • the strength and performance characteristics of lower temperature and/or lower pressure environment plastic tank systems are enhanced with the hybrid tanks of the present invention.
  • high temperature environments are those where tanks for applications where temperature is higher than 220°C, and, particularly where temperatures and pressure are both at a high level. For example, at high temperatures, internal pressure is higher, for example greater than 30 psi.
  • aspects of the present invention therefore, provide for extended application ranges for hybrid tanks than either cast aluminum or plastic end tanks alone, particularly for use in an automotive vehicle, with lower weight with good performance versus cast aluminum only end tanks, and potentially lower cost (for example, through less time to manufacture and elimination of machining, welding and allowing integration of features not possible through metal casting methods) versus prior heat exchanger art tanks. Otherwise stated, aspects of the present invention allow for a larger degree of design freedom (more integration of features which can not be feasible through metal casting processes).
  • first material for example, plastic or plastic like parts, and features of a heat exchanger to exist in conjunction with parts and features made of other, for exmple, different material (a second material).
  • a second material it is meant materials that have different characteristics, such as different strength levels, stress modulus, stiffness levels, or the like.
  • an other material could be a material that has elastic like properties, or rigid properties; in the case of two different plastic based materials, for example, one the plastic or plastic part can be stiff relative to the other part, or visa versa.
  • the other material can be another plastic or plastic like material with characteristics differing from the material, or the other material could be a metal or metal alloy based material.
  • the plastic or plastic like parts can be formed or produced, for example, with processes such as, but not limited to, injection molded, blow molded or compression molded or plastic cast components. Produced parts, for example, do not require secondary operation at all or require minimum secondary operations after a main or principle manufacturing step in order to produce the end product.
  • a hybrid tank therefore, as used herein, is an end tank formed using at least two different materials. In general, the first and second materials, therefore, have different structural characteristics. As used herein, by structurally less flexible, it is meant a material that is more stiff or rigid, and, therefore can lead to a longer lasting or higher performance versus a less stiff or rigid material.
  • materials such as plastic or plastic like materials and metal or metal alloy materials are used together to form the hybrid tank.
  • an end tank is made conforming to a plastic and metal hybrid design, wherein routine machining, such as in the prior art for metal end tanks, is eliminated or minimized.
  • Various aspects of the present invention therefore, extend the application range possible for heat exchanger, and, especially for high temperature and/or pressure environment heat exchangers such as CACs (Charged Air Coolers) or intercoolers.
  • CACs Charge Air Coolers
  • intercoolers By providing for combined properties of two or more materials, strengthened tanks at lower weight and cost than cast aluminum tanks or tanks, gain advantages, especially in terms of design freedom.
  • Tubes are present in automotive heat exchangers and heat exchanger assemblies.
  • the plurality of tubes can have at least one tube with a plurality of sub-passageways extending along a length of the at least one tube and wherein each of the sub-passageways of the at least one tube has a cross-sectional area perpendicular to the length of the at least one tube that is between about 0,02 mm 2 and about 1.00 mm 2 .
  • End tanks such as those used in the heat exchanger assemblies of the present invention, may be used in various applications where automotive fluids are handled. Particularly in high pressure and/or temperature environments, where plastic only end tanks can not meet, or with great difficulty, meet specifications, (such as EGR coolers, or charged air intake tank, or intake manifolds), hybrid tanks not only have the structural features necessary to meet such specifications, but also are light and formable enough to be used in a variety tight space packaging, as well as high temperature/pressure environments.
  • specifications such as EGR coolers, or charged air intake tank, or intake manifolds
  • Heat exchanger assemblies and, especially, heat exchanger assemblies operating in high temperature and/or pressure environments, allow increased temperature and pressures range of application of lower weight and cost tanks.
  • Hybrid tanks as in the various aspects of the present invention, are therefore useful to replace cast aluminum, or even other metal tanks, such as stamped and brazed aluminum tanks.

  • the metal shell provides stiffness which allows areas of the hybrid tank to resist high pressures at specified temperatures.
  • the plastic part or parts of the hybrid tank (plastic adjuncts) are formed or otherwise assembled together with the metal shell such that they have essentially leak proof seals between metal and plastic areas of the hybrid tank, thereby rendering the tank so-called 'leak tight'.
  • the metal shell of the heat exchanger tank may comprise metal or metal alloy derived from a sheet of metal or metal allow (sheet metal).
  • sheet metal The combination of sheet metal and plastic takes advantage of the properties of sheet metal to take large loads (sheet metal form (which is in 0.3 ⁇ t ⁇ 4 mm thickness), versus, for example, the typical cast aluminum tanks of width or thickness which are often greater than or equal to 3 ⁇ t ⁇ 6 mm, wherein t is the average thickness.
  • the properties of the plastic particularly, for example, lower densities compared to aluminum, allow for a lighter overall tank and subsequently heat exchanger and assembly weight, and ease of manufacturing of complex features on or associated with the hybrid tank.
  • the area of hybrid tanks at the junction of contact of metal and plastic parts is called, herein, 'plastic-metal sections'. Together, the plastic-metal sections form part of the overall tank and the tank comprises the metal shell and plastic adjuncts.
  • plastic-metal sections also referred to on occasion as mechanical joints or mechanical interface joints can be envisioned in many ways.
  • Simplistic joint is shown where plastic flows through strategically placed perforations in the metal and thus creating a mechanical joint.
  • the number and type of mechanical joint varied per location through out the tank and also from one tank design to other tank designs.
  • the purpose of the mechanical joint is to allow some deformations and loads seen during the duty of the part.
  • the plastic adjuncts and the metal sections can be bonded, glued, or otherwise held together, either by a general bonding process, by adhesives, or by forming an interfacial layer of a product to help form a seal.
  • Plastic-metal sections can be bonded together.
  • aspects of the present invention also provide for the use of a coating, such as thermal barrier, or thermally dissipative, coatings, that is applied to various areas of the hybrid tank.
  • a coating such as thermal barrier, or thermally dissipative, coatings, that is applied to various areas of the hybrid tank.

  • liquid coatings are numerous and are found in standard formulations and used in the art on a regular basis.
  • One such example includes coatings such as thermal barrier type coating like IC-105 from Techline Coating. Preferred are coating that practically eliminate or highly reduce oxidation by isolating the majority of the base material from higher temperatures.
  • thermally dissipative coatings can include, for example, a thermally cured heat emitting coatings, that can be combined with other materials, such as pigment, to provide corrosion protection as well as being applied as a thin film.
  • a coating is applied on the interior or exterior or both walls of the hybrid tank.
