Probably, many who became the owner of a satellite receiver, faced with the problem of intense heating of the receiver body during its operation. A satellite receiver can simply fail - due to overheating.
For a homemade digital satellite receiver cooling system I needed:
Instruments:
1) Stationery knife,
2) Pliers
3) scissors,
4) Soldering iron and lead-tin solder,
5) Glue gun and hot glue,
6) Lighter.
Materials:
1) Heat shrink tubing or insulating tape,
2) Computer cooler,
3) Black and red wires,
4) aluminum wire,
5) Disassembled usb connector.
The cooler wires were already short and so as not to solder once again and to look more original, I decided to solder the soldered short cooler wires and solder the longer wires. To do this, unsolder the old wires.
We clean longer wires from insulation with a clerical knife.
This process must be done at both ends of the wire.
We cover the cleaned places with lead-tin solder using a soldering iron.
Solder these wires to a computer cooler.
Glue the sticker back. In my case, this is already tape.
Now we take the usb connector.
Now we put heat-shrink tubes on the wires. We put one with a large hole on both wires, and two with a small hole we put on each of the wires.
We disassemble the usb connector case.
Solder the wires to the contacts of the usb connector. At the same time, we observe the polarity. If soldered incorrectly, the fan will not work.
We put heat-shrink tubing on soldered places.
Using a lighter we compress them.
Now we put a large heat-shrink tube into two small ones and we get, as it were, one whole wire. Lighter heat this pipe.
Assemble the body of the USB connector back.
Here's what we got at the moment.
Now you should make protection from the blades. Suddenly, they’ll accidentally put something, for example, a newspaper, and the fan blades will stop and the electric motor may burn out.To protect the blades, we take an ordinary aluminum wire.
We straighten the aluminum wire with pliers or simply with your hands, as it is very easily bent.
We use a pair of pliers to bend a right angle with the wire as shown in the photograph.
Glue the wire to the fan with hot glue.
We make three more of the same parts from aluminum wire.
With a glue gun we glue all 3 parts to the fan, as shown in the photo.
So that the cooling system does not slip on a flat surface, we apply hot melt glue on the bottom of the fan as legs.
That's all, the home-made simple cooling system for the digital satellite receiver is ready. Now it must be put on the receiver and connected to power.
We connect the fan to the built-in usb port and the fan will work.
Although a 12 V fan from 5 V blows weakly, but this is enough to cool the satellite receiver. Now it does not heat up, but remains cold.
And that’s all for me, thank you all for your attention! Good luck to everyone and bye!
