Definitions

  • the subject matter disclosed herein relates to heat exchangers. More specifically, the present disclosure relates to forming enhanced tubes for microchannel heat exchangers.
  • microchannel heat exchanger systems are refrigerant to air applications. These systems include a plurality of microchannel tubes, typically formed of aluminum. The tubes each contain a number of channels or ports through which a flow of refrigerant is circulated. Thermal energy from the refrigerant flow is dissipated to an airflow, typically in a cross-flow orientation relative to the flow in the tubes. Such microchannel heat exchangers are typically applied to motor vehicle cooling systems.
  • Typical industrial air conditioning and refrigeration systems include a refrigerant evaporator or chiller. Chillers remove heat from a cooling medium that enters the unit, and deliver refreshed cooling medium to the air conditioning or refrigeration system to effect cooling of a structure, device or a given volume. Refrigerant evaporators or chillers use a liquid refrigerant or other working fluid to accomplish this task. Refrigerant evaporators or chillers lower the temperature of a cooling medium, such as water or other fluid, below that which could be obtained from ambient conditions.
  • a cooling medium such as water or other fluid
  • chiller is a flooded chiller, which typically includes a number of typically round heat exchange tubes submerged in a volume of a two-phase boiling refrigerant, having a specified boiling temperature.
  • a cooling medium often water, is processed by the chiller.
  • the cooling medium enters the evaporator and is delivered to the heat exchange tubes.
  • the cooling medium passing through the tubes releases its thermal energy to the boiling refrigerant.
  • DE 101 15 513 A1 shows a heat exchanger, especially an evaporator in an air-conditioning system of a motor vehicle, used for transferring heat between a first and a second heat medium comprises a number of flat tubes forming a block through which the first heat medium flows.
  • the flat tubes are arranged in parallel so that channels for the second heat medium entering at one end of the block are formed in between adjacent flat tubes.
  • the flat tubes extend in the direction of the block depth at least over a partial section at an angle to the end surface of the block.
  • US 3 092 470 A shows a method of preparing narrow strips of material each having an internal discontinuity between surface laminations, the laminations being connected at the lateral edges of the discontinuity, which comprises preparing a billet of material with a plurality of internal longitudinal channels spaced laterally from one another and from the longitudinal edges of the billet by portions of solid metal extending from face to face of the billet. The method prepares sheet stock having longitudinal external weakenings therein.
  • DE 10 2009 051280 shows a tube having impression-free sections alternately arranged in a tube longitudinal direction that is parallel to a tube longitudinal axis, and molded sections comprising impressions attached in a tube wall.
  • One of the impression-free sections is arranged between the molded sections, and the other impression-free section is arranged at both tube ends.
  • the molded sections have longitudinal extension of 25 to 100 mm in the tube longitudinal direction.
  • a method of forming a heat exchange tube for a refrigerant-flooded evaporator includes urging a billet into an extruded section and forming the billet into two tube halves including an outer wall and an inner wall having a plurality of channel halves.
  • a textural element is formed at one or more of the outer wall and the inner wall via one or more rotating dies, and the two tube halves are joined to form the heat exchange tube.
  • FIG. 1 Shown in FIG. 1 is a schematic of a method of forming microchannel tubes 10 for a refrigerant flooded evaporator.
  • the method is utilized for forming the microchannel tubes 10 which, as shown in FIG.2 , include a tube body 12 that may be non-circular in shape, for example, oval or elliptical.
  • a plurality of channels 14, or ports, is configured for refrigerant flow therethrough.
  • the tube body 12 may include any number of channels, for example between about 2 and 20 channels.
  • the tube body 12 is about 1 inch in width and includes about 10-16 channels 14 therein.
  • the tube body may include about 4-6 channels 14 therein. It is to be appreciated that these embodiments are merely exemplary and other configurations are contemplated within the present scope.
  • the method begins with a billet 16 of a selected raw material.
  • the material is copper or a copper alloy, but other materials, for example, aluminum and aluminum alloys are contemplated within the scope of the present disclosure.
  • the billet is fed into a heating section 18 in pairs by a ram 20.
  • the billet 16 pairs are heated to a selected temperature, and then urged through an extrusion section 22, where the billet pairs 16 are shaped into tube halves 24, shown also in FIG. 3 .
  • Each tube half 24 includes an outer wall 26 and an inner wall 28 that includes a plurality of channel halves 30.
  • the extruded tube halves 24 are then urged through a texture section 32.
  • the texture section 32 includes one or more rotating dies 34 affixed to bearings (not shown) and driven by separate or shared drive motors (not shown).
  • the rotating dies 34 emboss textural elements or patterns into the outer wall 26 and/or the channel halves 30 of the tube halves 24.
  • the tube halves 24 then proceed to a unitization section 38 where they are secured to each other such as for example by brazing or solid state diffusion bonding. It is contemplated within the scope of the current invention that other suitable joining techniques may also be used.
  • the textural elements or patterns added to the outer wall 26 and or the channel halves 30 may take many forms.
  • the inner wall 28 is embossed with a plurality of dimples 40, or a plurality of grooves 42 or fins 44 that are configured to increase heat transfer between a cooling medium 46 flowing through the channels 14 and the outer wall 26 by improving mixing of the cooling medium 46 in the channels 14.
  • the grooves 42 or fins 44 may be arranged in a helical and/or cross-hatched pattern. As shown in FIG.
  • the textural elements on the outer wall 26 are ridges 48, pockets 50, or other similar shape with sharp edges to improve nucleate boiling of a volume of refrigerant 52 in which the tubes 10 are submerged.
  • the ridges 48 or other textures may be arranged helically of in a cross-hatched pattern on the outer wall 26.
  • the tube halves 24 are urged over a rotating die 34 which forms patterns or textures in the channel halves 30 of the tube halves 24.
  • the tube halves 24 then proceed to the unitization section 38 where they are joined.
  • the joined tube 10 then proceeds through another texture section 32, including more rotating dies 34 that apply textural elements or patterns to the outer wall 26 of the tube 10.
