How to dissipate energy/heat in solenoid valve + flyback diode circuit
I''ve calculated the energy as 0.5 * 8.15 mH * (0.45 A)^2 = 0.8 mJ, and the initial discharge power as 0.9 Ohm * (0.45 A)^2 = 0.18 W. What is the recommended way to dissipate this energy/heat safely? If I add a resistor, seems to me it would get the heat instead of the diode so it would be the same problem.

14. You conduct heat to places such as the enclosure. The result is that heat is removed, or dissipated from the heat generating source. If the pad is connected to a metal plate or larger surface you have given the heat source a larger surface area by which heat can be transferred to the air and therefore increased the ability of the entire ...

Energy dissipation analysis of elastic–plastic materials
Summing up all the stored energy E S t o r e d, one obtains: (20) E S t o r e d = E K + E S + E P. Rate of plastic dissipation, given by Eq. (9), can be integrated over time and space: (21) D P ( t) = ∫ V ∫ 0 t Φ ( x, T) d T d V where D P is the dissipation due to plasticity of the entire model at certain time.
How is heat dissipated from a satellite or any metal in space?
So any part of a space craft or satellite facing the sun will absorb heat (a net gain) and any facing away will radiate heat (a net loss). Satellite designers minimise the absorption of energy by the use of reflective foil wherever possible, and provide heat radiating fins in order to dissipate excess heat on the dark side of the satellite.

The heat output of data centres is around 30°C-35°C, and heat pumps can use water at this temperature as a heat source and increase the temperature to 70°C or 80°C. This heat energy can then be used to heat nearby homes, or to supply domestic hot water to commercial buildings such as gyms or hotels to help meet fluctuating demand.

Dissipating large amounts of energy fast, in space
That means that if you want to get rid of large amounts of heat, you can let the radiators run hotter. The power level of a sublimator is proportional to the temperature and the heat capacity of the evaporated material. The best heat capacity possible is that of hydrogen at 14.267J/gK 14.267 J / g K. Water is good too.

Better surfaces could help dissipate heat
The team concluded that the reason surface roughness greatly enhances heat transfer — more than doubling the maximum heat dissipation — is that it enhances capillary action at the surface, helping keep a line of vapor bubbles "pinned" to the heat transfer surface, delaying the formation of a vapor layer that greatly reduces cooling.

How to dissipate a lot of current
The smallest way to dissipate that amount of power via heat is fans and load resistors attached to heatsinks. It''s noisy and warms the workshop up nicely. The other way is to water cool the loads. For less than 30V loads you can always submerge it in a bath of water and have the inflow and drain taps cracked open.
Cheapest way to dissipate energy (discharge battery)
Heat or boil water, and you basically never have to worry about it overheating. The tough part here is matching to the voltage. AC loads are meant for rms voltages of 120VAC or 220VAC (or others) depending on your location, and if you have an rms load of 80-100V that would work ok with a 120VAC load.
