Abstract

A mounting rail is provided that includes a DIN rail and one or more heating cable channels. A channel defined by the DIN rail may include one of the heating cable channels. Heating cables may be installed in the heating cable channels using adhesive and/or heat transfer material to form an electronics heating module. The heating cables may be self-regulating heating cables. The mounting rail may include multiple heat transfer fins that transfer heat generated by the heating cables to environment surrounding the mounting rail. A terminal block may be mounted on the DIN rail and may supply electric power to the heating cables.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of U.S. patent application Ser. No. 16/791,813, filed Feb. 14, 2020, which claims priority to U.S. Provisional Patent Application No. 62/806,064 filed Feb. 15, 2019, the disclosures of which are incorporated by reference in their entirety. BACKGROUND OF THE INVENTION Electronics modules such as temperature controllers are commonly housed in weatherproof enclosures and used in outdoor environments. In extreme conditions, these environments may reach temperatures as low as −55° C. or even colder. Electronic components however, are usually only rated for operation in temperatures of −40° C. or warmer, and may malfunction or even suffer permanent damage if operated at excessively low temperatures. To enable operation at very low temperatures, electric heaters are sometimes used to preheat the electronics in an enclosure to a safe operating temperature. For use in hazardous locations (e.g., those in which an explosive gas atmosphere may occasionally or regularly occur in normal operation), special precautions must be taken with heaters, and consequently the cost for heating units may be high, in the order of hundreds of dollars for a small (50-100 watt) heater. SUMMARY OF THE INVENTION In an example embodiment, a mounting rail may have a first side and a second side, and may include a DIN rail disposed at a first side, and a heating cable channel disposed at the second side, the heating cable channel comprising a slot configured to receive a heating cable. In some embodiments, the mounting rail may be formed from extruded aluminum. In some embodiments, the DIN rail may define a channel that opens in a first direction. The slot of the heating cable channel may open in a second direction that is substantially perpendicular to the first direction. In some embodiments, the mounting rail may include a structure that forms at least a bottom surface of the DIN rail and a first sidewall of the heating cable channel. In some embodiments, the heating channel may include an additional slot configured to receive the heating cable. The additional slot may open in the second direction. The mounting rail may additionally include a first plurality of fins disposed between the slot and the additional slot and extending in a third direction that is substantially opposite the second direction and substantially perpendicular to the first direction, and a second plurality of fins disposed between the slot and the additional slot and extending in the second direction. In some embodiments, the mounting rail may include a second heating cable channel disposed on a third side of the mounting rail that is opposite to the second side, the second heating cable channel comprising a second slot that opens in a third direction that is substantially opposite to second direction and that is substantially perpendicular to the first direction. In some embodiments, the mounting rail may include a second heating cable channel disposed at the first side, the second heating cable channel comprising a second slot configured to receive a second heating cable. In some embodiments, the DIN rail may define a channel that opens in a first direction. The second slot of the second heating cable channel may open in the first direction. The channel defined by the DIN rail may include the second heating cable channel. The slot of the heating cable channel may open in a second direction that is substantially opposite to the first direction. In some embodiments, the mounting rail may include a first plurality of fins disposed at a third side of the mounting rail that extend in a third direction that is substantially perpendicular to the first and second directions, and a second plurality of fins disposed at a fourth side of the mounting rail that extend in a fourth direction that is substantially perpendicular to the first and second directions. In an example embodiment, an electronics heating module may include a mounting rail that includes a DIN rail and a heating cable channel, and may include a heating cable disposed in the first heating cable channel. In some embodiments, the DIN rail may include sidewalls that define portions of the heating cable channel. In some embodiments, the heating cable channel may be a first heating cable channel that includes first slots that open in a first direction. The heating cable may be a first heating cable that is disposed in the first slots. The mounting rail may additionally include a second heating cable channel that includes second slots that open in a second direction that is substantially opposite to the first direction, a second heating cable that is disposed in the second slots of the second heating cable channel, a first plurality of fins extending outward in a third direction that is substantially perpendicular to the first and second directions, and a second plurality of fins extending outward in a fourth direction that is substantially o
