fredge freezer heatsink in the sun

[pspec]

Hi

This isn’t the right site for this so I’ll post in off topic as I’m sure you guys will have an idea.

I’ve got this 6’ 6” fridge freezer which as a large heatsink covering the whole back.

Now my thinking is the gas takes the heat out of the fridge to the desired temp travels to the black heatsink on the back and expels it in to the room.


Now my problem is I’ve had to place the fridge freezer by a full length glass door where 6 feet by 6 inches of the heat sink is exposed to sun light (when the midday sun hits the door the heat pours in). As the heat sink is black it’s going to take on heat from the sun and there’s a chance the heat sink could work in reverse or at least make life a lot harder for the fridge.


So first would you agree and second if I made a tinfoil shield covering the exposed area (with 2” air gap between foil and heatsink) so the sun couldn’t shine upon the sink should that sort the problem..

Thanks

It's not a heat sink, it's a condensing coil. As long as you have enough air space around it, it'll be fine.

Don't bother with the foil, it'll just look dreadful.

Any fridge that's in direct sunlight will cost considerably more to run (up to 50%) due to inefficiencies.

White painted hard-board / mdf / card --- just bounce that sunlight without dazzling ,
( or melting anyones car like that "Mobile Phone" building )

thats not actually correct m8 the hotter the ambient temperature around the condenser the harder the fridge has to work as theres less heat transfer caravan fridges that work well in the uk struggle when the ambiant temp gets above 25 just as a combi has a temp rise figure so fridges have a temp loss figure
