A gas detector comprising:
- a housing defining a cavity, the housing comprising a top part and a bottom part, the top part coupled to the bottom part;
- and
- a display module positioned within the cavity of the housing, the display module comprising:
- a first PCB and a second PCB, each generating heat in response to operation of the display module;
- a base plate;
- a metal enclosure;
- and
- a thermal gap pad, wherein the metal enclosure is positioned on top of the base plate, and the thermal gap pad is disposed in between the metal enclosure and the second PCB, wherein the second PCB is positioned in between the first PCB and the thermal gap pad,
- wherein the display module is received by a display module support disposed on the bottom part of the housing, the display module support comprising a contact metal plate and support portions,
- wherein the metal enclosure is in contact with the contact metal plate and the support portions, wherein the contact allows direct transfer of heat from the metal enclosure to the support portions and the contact metal plate.
