Definitions

  • the top and bottom lattices have similar or same structures and are disposed at a top section of the batteries and at a bottom section of the batteries.
  • the top or bottom lattice of the battery holder includes a plurality of housing or enclosures that are shaped, for example, as pipes, tubes, cylinders, or another shape that conforms to or matches with a shape of the battery.
  • the housing or enclosures extend from a flat surface of the lattice and wrap around the side surfaces of the batteries.
  • Each of the batteries fits through one of the housing or enclosures of the top lattice at the top section of the battery and fits through one of the housing or enclosures of the bottom lattice at the bottom section of the battery.
  • the housing or enclosures support the batteries in vertical orientation and dissipate heat from the batteries to a heat sink.
  • the housing or enclosures are tubes.
  • Each tube of the lattice is adjacent to six tubes and is connected with each of the six tubes through a bridge or path.
  • the bridge extends from an outer surface of the tube to an outer surface of the adjacent tube.
  • the bridges between the tubes function as heat path to further enhance the heat flow in the lattice.
  • the lattice draws heat away from the batteries and dissipates the heat to a heat sink that connects with the lattice.
  • the batteries are stacked between the top lattice and the bottom lattice in a side-by-side relationship such that each of the batteries fits through one of the tubes of the top lattice to contact a coil spring at a top terminal of the battery and through one of the tubes of the bottom lattice to contact another coil spring at a bottom terminal of the battery.
  • the tubes of the top and bottom lattices isolate the batteries electrically from adjacent batteries in adjacent rows and columns.
  • the top and bottom lattices are made of a polymer that is electrically insulating and flame-resistant, for example, Acrylonitrile butadiene styrene (ABS) or polycarbonate.
  • the top and bottom lattices are made of a mixture of glass fiber reinforced polyamide 6, thermal conductive filler, flame retardant and other additives.
  • this mixture material has an in-plane thermal conductivity of 1.0 W/m ⁇ K and a through-plane thermal conductivity of 5.0 W/m ⁇ K, which is higher than the thermal conductivity of regular plastics (typically 0.1 -0.25 W/m ⁇ K) .
  • the bottom surface 342 of the bottom thermal lattice 320 and the top surface 340 of the top thermal lattice are in contact with an external heatsink or radiator. Heat generated by the batteries are drawn to the external heatsink through the cylinders that wrap around the side surfaces of the batteries.
  • the tubes are sized and shaped to receive cylindrical batteries.
  • a diameter of a tube corresponds with or is slightly larger than a diameter of a battery that fits into a tube.
  • the tubes are spaced apart such that each tube encircles a section of a battery to maintain the batteries in stable vertical orientation with respect to each other.
  • the tubes are arranged in a grid of rows and columns along a perimeter of the ends of the flat surface 412.
  • the tubes can be arranged in different patterns or geometries.
  • the tubes are arranged in a pattern such that each tube is adjacent to six neighbor tubes and connect to the six neighbor tubes through a bridge or a path or an interconnection (an example bridge more fully shown in Fig. 5A) , except for the tubes along the edges of the lattice.
  • the interconnections between the tubes help to draw heat away from the batteries in a faster way. In this configuration, the overall thermal dissipation performance of the lattice is enhanced.
  • the interconnection that links neighbor tubes further reduces deformation and distortion of the lattice during manufacturing.
  • Figure 5B shows a partial view of a top side of the lattice 500 of Fig. 5A in accordance with an example embodiment.
  • integrally formed means formed with material common to the rest of the unit and the connection having no mechanical joints. Integrally is distinguished from two-piece or multi-piece construction in which separate pieces are connected together.

Abstract

Un support de batterie supporte une pluralité de batteries cylindriques et dissipe la chaleur des batteries cylindriques. Le support de batterie comprend un treillis supérieur et un treillis inférieur. Le treillis supérieur comprend une pluralité de tuyaux pour supporter une section supérieure des batteries cylindriques. Le treillis inférieur est disposé à l'opposé du treillis supérieur et comprend une pluralité de tuyaux pour supporter une section inférieure des batteries cylindriques. La pluralité de tuyaux du treillis supérieur s'ajustent autour et recouvrent la section supérieure des batteries cylindriques et la pluralité de tuyaux du treillis inférieur s'ajuste autour et recouvre la section inférieure des batteries cylindriques. Chacun des tuyaux s'enroule autour d'une surface latérale des batteries cylindriques pour maximiser une zone de contact entre le support de batterie et les batteries cylindriques pour dissiper la chaleur des batteries cylindriques à un dissipateur thermique à travers le support de batterie.
