Cooling method small volume
Cooling method small volume
(OP)
Hi!
I am designing a food delivery machine that needs to have a cooled chamber where food is stocked before delivery. The dimensions of this chamber are roughly 125*100*700mm, with only 60mm of free space on the sides and no possibility to adapt anything on the bottom, the top side is free. The temperature difference isn´t too high, as the machine will be located in a shop in a tempered climate country in center Europe.
I am thinking of using TEC modules but was wondering if there are other cooling methods more adapted to this configuration?
Thanks!

RE: Cooling method small volume
I have seen them used, with a water system to cool them.
Could you simply cool the entire machine with a chiller and blower (like a soda machine)?

I planned to cool the hot side with a fan and a heat sink but I just have 60mm space between 2 chambers, it might not be the best configuration for the ventilation of the hot plate...

How about ice? Wet or dry.
Or a chunk of cold metal.

You won't be able to turn them on and off one at a time, but it will be simpler.

MintJulep: I´m afraid we can´t control the temperature using dry ice?
I have never seen or used cold metal for cooling, do you have any link where I could get some information?
EdStainless: That could be a solution, the challenge will be the design of the cold box, because I need to be able to remove it in order to refill it. The cold plate could be be fixed and the cold box would fit over it.

> It has to stay cold the whole time it is in the cold box
> Ideally electric, as we don´t have any pneumatic or hidraulic system installed, but we could install it if neededç
> Yes, we do have air flow
> Food must be kept between 2 and 6ºC
tkordynam:
I´m pretty confident that it´s feasible, but I was wondering if there are other relevant solutions, and maybe better in one way or another than Peltier modules.
RE: Cooling method small volume
OK, but how long? minutes, days, years?
Your requirement for ± 3°C pretty much limits it to TECs, though, with fans to maintain air flow over the heat sink. People have designed fans for graphics card in PCs that fit in a 0.6-inch slot, which is 15.2 mm.
