Backlight unit for a motor vehicle display apparatus integrated with a heat transfer device and method thereof

A method of assembling an edge-light motor vehicle display apparatus for use in a motor vehicle, the method comprising:

• providing at least one heat transfer device, the at least one heat transfer device comprising
• an anterior capillary tube operable to integrate with a rear side of a backlight unit, the anterior capillary tube further operable to dissipate heat from an anterior of the backlight unit,
• a posterior capillary tube operable to be positioned further away from the rear side of the backlight unit than the anterior tube, the posterior capillary tube further operable to dissipate heat from a posterior of the backlight unit, and
• a phase changing medium operable to fluidly transfer between the anterior capillary tube and the posterior capillary pillar tube during a heat transfer process,
• wherein the phase changing medium is operable to phase change between a gaseous state and a liquid state during the heat transfer process, to release latent heat from the rear side of the backlight unit;
• providing a housing fora rear side of the motor vehicle display apparatus, the housing comprises at least one slot;
• and
• extending at least a portion of the at least one heat transfer device with the at least one slot of the housing, thereby yielding an edge-lit motor vehicle display apparatus integrated with at least one heat transfer device.
