Abstract
The disclosure includes a fixed retail scanner including a scanner base unit comprising one or more imagers to view a read zone, and a top-down reader having a head and an elongate stand operably coupled to the scanner base unit. The top-down reader includes a printed circuit board including one or more processors and optical components disposed within the head of the top-down reader, and a heat management system including a heat pipe having a first end disposed within the head and extending into a sealed air chamber within the stand to dissipate heat from the one or more processors into the sealed air chamber. Related methods for heat management of a top-down reader are also disclosed.
Claims18
A fixed retail scanner, comprising:
- a scanner base unit comprising one or more imagers to view a read zone;
- and
- a top-down reader (TDR) including:
- a head including an optical cavity therein housing a printed circuit board including one or more processors and optical components disposed therein;
- and
- an elongate stand attached to the head and coupled with the scanner base unit extending in a vertical direction such that the optical components within the head are oriented toward the read zone from a top-down perspective, the elongate stand including a sealed air chamber that is separated from the optical cavity by an airflow seal at an interface therebetween;
- a heat management system including a heat pipe having a first end disposed within the head and extending into the sealed air chamber within the elongate stand to dissipate heat from the one or more processors into the sealed air chamber, wherein the heat pipe is configured to employ a phase transition therein to transfer heat from an evaporator region to a condenser region.
A fixed retail scanner comprising:
- a scanner base unit comprising one or more imagers to view a read zone;
- and
- a top-down reader (TDR) having a head and an elongate stand operably coupled to the scanner base unit, the top-down reader including:
- a printed circuit board including one or more processors and optical components disposed within the head of the top-down reader;
- and
- a heat management system including:
- a heat pipe having a first end disposed within the head and extending into a sealed air chamber within the elongate stand to dissipate heat from the one or more processors into the sealed air chamber;
- an evaporator region at a first end of the heat pipe including a heat plate coupled to the one or more processors;
- and
- a condenser region at a second end of the heat pipe including a heat exchanger disposed within the sealed air chamber.
A fixed retail scanner comprising:
- a scanner base unit comprising one or more imagers to view a read zone;
- and
- a top-down reader (TDR) having a head and an elongate stand operably coupled to the scanner base unit, the top-down reader including:
- a printed circuit board including one or more processors and optical components disposed within the head of the top-down reader;
- and
- a heat management system including:
- a heat pipe having a first end disposed within the head and extending into a sealed air chamber within the elongate stand to dissipate heat from the one or more processors into the sealed air chamber, wherein the elongate stand region includes an internal cabling path parallel with the sealed air chamber.
