Apparatus for electronic component and heating cable mounting
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.
1. A mounting rail having a first side and a second side, the mounting rail comprising:
a DIN rail disposed at a first side, wherein the DIN rail defines a channel that opens in a first direction;
a heating cable channel disposed at the second side, the heating cable channel comprising a slot configured to receive a heating cable and an additional slot configured to receive the heating cable, the slot and the additional slot facing the same direction, wherein the slot opens in a second direction that is substantially perpendicular to the first direction;
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.
2. The mounting rail of claim 1 , wherein the mounting rail is formed from extruded aluminum.
3. The mounting rail of claim 1 , further comprising:
a structure that forms at least a bottom surface of the DIN rail and a first sidewall of the heating cable channel.
4. An electronics heating module comprising:
a mounting rail comprising:
a DIN rail;
a first heating cable channel including first slots that open in a first direction; and
a second heating cable channel that includes second slots that open in a third direction that is substantially opposite to the first direction, wherein the DIN rail defines a channel that opens in a second direction that is substantially perpendicular to the first direction;
a first heating cable disposed in the first slots; and
a second heating cable that is disposed in the second slots of the second heating cable channel.
5. The electronics heating module of claim 4 , wherein the mounting rail further comprises
a first plurality of fins.
6. A method comprising:
extruding aluminum to form a mounting rail that comprises a DIN rail and a heating cable channel having a slot:
applying adhesive the slot;
inserting a first heating cable into the slot of the heating cable channel of the mounting rail, such that the first heating cable contacts the adhesive; and
stacking a second heating cable over the first heating cable in the slot of the heating cable channel of the mounting rail, such that the second heating cable contacts the adhesive,
wherein the slot includes a first slot and a second slot, and the mounting rail further comprises a first plurality of fins interposed between the first slot and the second slot.
7. The method of claim 6 , wherein the first slot opens in a first direction, wherein the DIN rail defines a channel that opens in the first direction and that overlaps the first slot.
8. The method of claim 7 , wherein the heating cable channel comprises a first heating cable channel and a second heating cable channel, wherein the first heating cable channel includes the first slot, wherein the second heating cable channel includes the second slot that opens in a second direction that is substantially opposite to the first direction.
9. The method of claim 6 , wherein the first slot opens in a first direction, wherein the DIN rail defines a channel that opens in a second direction that is perpendicular to the first direction.
10. The method of claim 9 , wherein the heating cable channel comprises a first heating cable channel and a second heating cable channel, wherein the first heating cable channel includes the first slot, wherein the second heating cable channel includes the second slot that opens in a third direction that is substantially opposite to the first direction.
