What's the procedure for soldering the heat pipes on a heat plate? What materials do we need? what type of solder? What temperature can we solder at without damaging the heat pipes and vaporizing the liquid inside the pipes?
Answer: To get the heat pipes set into the heat plate, we should solder the pipes. In order to do this, we need to first nickel plate the aluminum plate which provides it with corrosion and wear resistance (most likely just buy an aluminum plate that has been nickel plated, basically just makes it an aluminum alloy). To actually solder the heat pipes into the grooved plates, we need a solder material (most likely lead-free) and have a blowtorch to make it a sort of paste. This paste should be create a super thin layer in the grooves and the heat plates should be placed on top like a press fit. The maximum temperature we can solder at is around 138 degrees C and the heat pipes cannot exceed 250 degrees C in general or else the water inside will boil and explode the heat pipe.
Assuming the dissipating plates are aluminum, how are we going to put grooves in it for the heat pipes?
Typically, for ev EV battery boxes, and assuming we're going with a horizontal orientation, at what angle are the pipes usually at? We will probably have to bend the heat pipes, what's the safest method for bending these pipes without damaging them? (assume we're using copper heat pipes with water inside)
