He is not asking how to dissipate heat. He wants to actually use the heat to boil water for cooking, for example.
First, you are aware this miner will not get you more than a few dollars per quarter, right? If electricity price is also added your roi is negative or close to that as energy price in Brazil is very expensive

You are asking about thermodynamics energy. I don't think you will have much use to that with a single miner. Perhaps with several dozens of them you could start thinking on funneling their heat or something like that.

In the case of boiling I can only imagine that Spoondoolies units are capable of reaching boiling temperature, the Spoondoolies ASICs can run at above 100C. It would be an interesting project to use water evaporation to cool ASICs.

As I don't know the prices in Brazil I couldn't guess what would be the roi nor do I have the experience for operating miners in hot climates.

Electric prices are low here in Iceland about $0.074 er kWh on the site where the picture is taken. The miners are over a year old, they made roi long time ago. The miners still net a profit and give about $0.102 per kWh used, which gives a profit of $0.028 per kWh per hour. That is about $250 per annum or $20.44 per month. It's not a whooping amount but it's essentially free heating in a cold, horrid and desolate place.

The miner heat is currently used to heat up the shed, that's about it. The only realistic use I can find for miners beyond profit.
