Cold room combination vent and light

A cold room vent comprising:

• a mount mountable to a cold room structure;
• a valve body coupled to said mount, said valve body defining a heat chamber having an air passage entrance opening;
• at least one valve coupled to said valve body;
• a thermally conductive heat sink plate mounted closely adjacent said valve body, said heat sink plate having a front surface and a rear surface facing said valve body, said rear surface having a projection extending through said air passage entrance and into said heat chamber, and
• a light source coupled to and in thermal communication with said heat sink plate,
• whereby heat generated by the light source is thermally conducted to the thermally conductive heat sink plate wherein the projection transfers heat to the heat chamber to warm the at least one valve.

A cold room vent comprising:

• a mount mountable to a cold room structure;
• a valve housing coupled to said mount, said valve housing defining a heat chamber having an air passage entrance opening;
• at least one valve coupled to said valve housing;
• a thermally conductive heat sink plate mounted closely adjacent said valve housing air passage entrance opening, said heat sink plate having a front surface and a rear surface facing said valve housing, said heat sink plate having a plurality of vent openings therethrough, said heat sink plate also having a projection extending from said rear surface between two said vents of said plurality of vents and into said heat chamber, and
• a heat source coupled to and in thermal communication with said heat sink plate,
• whereby heat generated by the heat source is thermally conducted to the thermally conductive heat sink plate wherein the projection transfers heat to the heat chamber to warm the at least one valve.
