Home-made cooling for satellite receiver

Home-made cooling for satellite receiver

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!

a very good solution for cooling digital set-top boxes.
I’m not an expert and the only question for the author is: on a computer, the fan on the power supply always blows out so as not to drive dust into the computer. maybe we need to turn the cooler over at the digital set-top box?
PS: I made such a cooler and set it to blow - and the console is as cold as a refrigerator. however, it didn’t get very hot: up to 40 degrees ...
Hello! Yes, the people are also warming the receivers, the author of course + for trying, but of course it would have been prettier from the inside, such a cooler is needed if your receiver works without interruption, well, I have the receiver as a server, you can’t turn it off, put the cooler inside and all years 5 is working fine !!

And with the TVs there was some garbage that’s behind joins, and in it a card inserted ...

yes They are both inserted ...)))
It’s just that you don’t "push" the card there.))) We need a module, for each "satellite", NTV +, "Tricolor" ... your own module and your own card. The cost of the module is approximately the same as the cost of an external tuner.

I’m not rummaging ... I’m more and more on the carpentry! )))))). "Nerd" talked about some kind of "SAM module" (it seems so called). At that moment I understood the point, now I forgot again (because I’m not interested). And with the TVs there was some garbage that connects from behind, and the card is inserted into it ... They are lying in the drawer along with scarts and other crap that came with it ...
And I belong to those 13, it seems to the percent that 3D can not see !!! Imagine disappointment when I bought televisions with shutter technology .... and on you! It turned out, hello! ))))
There are 3D channels in the apartment by cable. And in the big TV there is a 2D generator - like, he can remake any HD channel in 3D ... But, my daughter says that this is far from it! So, there’s a little effect ...
And we somehow “didn’t get accustomed” to 3D, even with my daughter and wife (they see). It’s not interesting for them ... So, purely at the beginning it was interesting for them to look at all kinds of “Avatars” ... And now ... except for the guests, who don’t have 3D TVs at home ...
It’s just that you don’t "push" the card there.))) We need a module, for each "satellite", NTV +, "Tricolor" ... your own module and your own card. The cost of the module is approximately the same as the cost of an external tuner. But the module is certainly more convenient, immediately the signal goes from the "Plate" to the TV, especially when the TV weighs on the wall. Yes, and one remote.
It weighs in my kitchen with the module on NTV +, there used to be a 3D channel. And in the hall there is a Tricolor with a tuner. 3D now look in the recording.Acquired for recording 3D movies, 1TB hard drive.
Well, in the sense, on your own built-in tuner DVB-S2.
... I, as I already said, is far from this topic, therefore I will tell you in "amateurish language" ... In my house, the plate was still in the days of CRTs and analog broadcasting. I rarely live there, so somehow I didn’t bother. Only a couple of years ago I changed the TVs to “smarts” in the house. I tried to insert the plate into the DVB-S2 socket. I don’t remember exactly, but something tormented there with a menu and called my friend “nerd for these matters” (who once positioned the plate to me). He told me that the built-in tuner is much weaker than the external one, but found a couple of dozen channels. I decided that it’s still more convenient anyway - for example, I need two remotes and a signal at a low frequency (switch each time). He advised me to buy a card (there was a module for it with the telecom).
... But it doesn’t matter to me so much that I didn’t bother. Moreover, at that time there was already good Internet and there is still a sea of ​​channels on the Internet (basically we watch them. Moreover, there is no plate on the second TV set, and only the “social package” is on the broadcast antenna - 12 channels and also Polish .
... There is also a local IPTV provider, which, they say, offers a good package with some advanced features, such as "delayed viewing" and other things ... But still I won’t call them ... Probably because I don’t need it.)) ))))

And in the house there is no cable, there the plate also hangs. But I do not bother, the tuner did not buy. It’s enough that the telly himself shows from it....

yes What is it like? Did I miss something?
And I don’t buy a tricolor .... In my apartment - in general, only a cable. There, a local operator launches more than a hundred channels for 5.50 per month (approximately 2.5 dollars). Half are ashdish. And in the house there is no cable, there the plate also hangs. But I do not bother, the tuner did not buy. It’s enough that the telly himself shows from it ....
Tricolor costs 900 r per year (or 1200 I do not remember). There are a lot of channels. Plus in nete you can see what you want. Does it make sense to bother with sharing? But this is now, and ten years ago yes, sharing was relevant.
Damn ... People, I look, "driven" so this ...)))). For example, I turn on the TV when I eat and when I go to bed .... Therefore .... well, I don’t rummage about it !!! ... One of the few areas that I'm not interested in !!! ... ))))
... People buy tuners, set up sharing ... What for ???? )))))). No, I don’t understand ...)))))) There are 30-40 channels, and that's enough! I remember the times when they were the only one on black and white televisions ....
It depends on what, of course, but I'm repairing it at the place. The power board heats up - diodes and canders, and they fly. You turn the board over - there is a dark spot, then 100% opposite it something burned out. The canders are puffed and dry by heat.
But really, are they warming up? I somehow did not notice when I used ... But it was a long time ago, maybe now it’s different ....
Something I don’t know is such a problem with the receiver, so that it would be "warmly" heated. And then, there the port is more likely for a "stop-video", as if necessary. I have it personally, busy with a 32 GB flash drive.

Yes, it was possible, but where to push such a fan there. The same, but less I did not find.
was it really too lazy to remove the cover
