2. The assembly of claim 1 , wherein the panel operates as a portion of a housing of the apparatus.
3. The assembly of claim 2 , wherein, when secured as part of the housing, the first surface forms part of an exterior surface of the apparatus and the second surface forms part of an interior surface of the apparatus.
4. The assembly of claim 1 , wherein the plurality of protrusions includes a set of mounting bosses and a set of thermal bosses.
5. The assembly of claim 4 , wherein the circuit board is mechanically attached to the second surface of the panel via attachment to the set of mounting bosses.
6. The assembly of claim 4 , wherein the set of thermal bosses physically compress a thermal interface material against the circuit board to conduct heat from the circuit board to the panel.
7. The assembly of claim 1 , further comprising a set of fasteners securing the wire harness to the rail.
8. The assembly of claim 1 , wherein:
the panel operates as a portion of a housing of the apparatus, and when secured as part of the housing, the first surface forms part of an exterior surface of the apparatus and the second surface forms part of an interior surface of the apparatus; and
the plurality of protrusions includes a set of mounting bosses and a set of thermal bosses, the circuit board being mechanically attached to the second surface of the panel via attachment to the set of mounting bosses, and the set of thermal bosses physically compress a thermal interface material against the circuit board to conduct heat from the circuit board to the panel.
9. An apparatus, comprising:
a housing for an electronic device, the housing having at least a plurality of sidewalls and a panel, the panel being a removable exterior housing panel;
a circuit board mechanically attached to a first side of the panel, the first side facing an interior of the housing when the panel is secured to the plurality of sidewalls;
a connector mount for mounting at least a connector terminal, and
the connector terminal, the connector terminal extending into the connector mount in a direction substantially parallel to a surface defined by the first side of the panel and perpendicular to the connector mount,
wherein the panel is a heat-conductive material to conduct heat from the circuit board to the panel,
the connector mount extends away from the panel in a direction perpendicular to the first side, and
the connector terminal is accessible externally from the housing for insertion of a connector in an insertion direction that is generally parallel to the surface defined by the first side of the panel.
10. The apparatus of claim 9 , further comprising a plurality of fins on a second side of the panel to dissipate heat into an environment, the second side is an exterior side of the housing.
11. The apparatus of claim 9 , further comprising a set of mounting bosses and a set of thermal bosses provided on the first side of the panel, wherein the circuit board is mechanically attached to the first side of the panel via attachment to the set of mounting bosses.
12. The apparatus of claim 11 , wherein the set of mounting bosses and the set of thermal bosses are formed integrally with the panel, and are of the heat-conductive material.
13. The apparatus of claim 9 , further comprising a wire harness coupling the connector terminal to the circuit board, wherein the first side of the panel further includes a rail for securing the wire harness.
14. The apparatus of claim 9 , wherein the connector mount is an integral extension of the panel.
15. An apparatus, comprising: an electronic device; and a housing for an electronic device, the housing having at least a plurality of sidewalls, a removable front panel, and a removable panel assembly; wherein the removable panel assembly includes: a panel of heat conductive material having a first side and a second side separated by a thickness of the heat-conductive material, wherein the first side includes a connector mount that extends away from the panel in a direction perpendicular to the first side, a plurality of mounting bosses, a plurality of thermal bosses, and a harness rail, and the second side includes a plurality of fins; a circuit board mechanically attached to the first side of the panel via at least a subset of the plurality of mounting bosses, the plurality of thermal bosses compress a thermal interface material against the circuit board, when attached, to conduct heat from the circuit board to the panel; a connector terminal mechanically attached to the connector mount; and a wire harness coupling the connector terminal to the circuit board, the wire harness being secured to the harness rail; and wherein the connector mount and the connector terminal define an opening for insertion of a connector in an insertion direction that is generally parallel to a surface defined by the first side of the panel.
16. The apparatus of claim 15 , wherein the electronic device is an inverter and the circuit board is a control card of the inverter.
17. The apparatus of claim 15 , wherein the removable front panel and the removable panel assembly are separately secured to the plurality of sidewalls.
