To many this item is just a used lump of aluminium but I am big on reusing or repurposing old electronic components and hardware, particularly from the point of view of sustainability.
Sustainability far more than NOT burying waste material back into the earth but consciously recognising the energy expended to create the item through it's various "stages" in life, beginning with the raw materials being extracted from the earth, processed, finished and then fitted into equipment - every single step used energy which is referred to as embodied energy.
To give an approximate representation of how much energy was used in the WHOLE production process of an item, I have created what I refer to as the Ee (Embodied Energy) value, measured in Mj
The Ee value is an approximation only and usually measured in Mj.
Coming up with an Ee value is an attempt to take into account the energy used for extracting and processing of the raw materials, manufacturing of the component, distribution of the component(s) and final assembly of the component. In fact the measurement of Ee can become extremely complicated and technical, many tertiary institutions are involved in this specialised field of science.
I have used various reliable sources online to arrive at approximate Ee values, these are approximations and the sole purpose is to raise awareness of the extraordinary energy consumed in the creation of various electronic components and hardware - it may give you cause to think twice before wasting all that energy and burying it in the ground, with the possible side-effects of poisoning the environment due to leeching.
HERE is a page I have created which gives some tables and more detailed information about specific Ee values for different materials plus a link which you can use as a starting point to investigate Ee for yourself.
Great for a custom project or upgrading the heat dissipation capabilities of equipment such as an audio power output stages or DC power supplies.
The heatsinks were installed in a nice German two channel power amplifier, each channel easily providing 150W RMS audio power.
This extruded heatsink is just a bit different compared to other heatsinks, I have two of these and they can be easily "interlocked" which creates a super heatsink 260mm in length.
Raw Aluminium Heatsink
Multiple fins (10) to assist in heat dissipation
No thermal resistance figures are available
MEASUREMENTS:
130mm x 97mm x 47mm
Special "channels" on either end of the heatsink so that two of the same type will interlock together, creating a large "super heatsink" - these fittings nice and tight for good thermal transfer between heatsinks.
Fins are 1.4mm (top) to 2.3mm (base) thickness
There are a total of 10 vertical fins, all are 42mm height off the base
WEIGHT: 650g
Four mounting holes are present on each side
This heatsink housed 4x 2-21F1A packaged power transistors, comfortably providing 150W RMS constantly
There is also a centre hole, this was originally used for the heatsink temperature sensor
COSMETIC CONDITION:
USED
CLEAN
NO damage to the heatsink base or fins
All previous Silicon grease has been removed
