Hmmm, I'm no engineer but it seems to me a solution is to have near perfect insulation combined a tank of compressed refrigerant. Vent it to the atmosphere. Even if the outside temperature it higher, there will still be a cooling effect to dispose of the waste heat. Compression would have to be very high since Venus has, what, 90 bar atmospheric pressure at surface level?

Also, are there any endothermic reactions that generate electricity? sounds like some sort of Maxwells Demon, so likely not...

You could still use a heat pump/radiative cooling of some sort if the heat in your radiator exceeded the outside temperature, but that would be one hell of a refrigerator!
