With this homemade product you can increase the temperature in the room. It is installed at the bottom of the heating radiator (in some cases, at the top). To manufacture this device, you will need a piece of plastic sewer pipe with a diameter of 110 mm and a length of 90 cm.
You will also need two computer fans and a power supply, to which the fans will need to be connected in parallel. Still need two plates with holes (you can use the old mounts from the cabinets).
First of all, it is necessary to cut a rectangular "window" in a plastic pipe with a length of 80 cm and a width of 6 cm. Then, stepping back from the edges by 50 mm, you need to drill holes of 6 mm for mounting the plates.
The main stages of work
After the holes are drilled at the edges, one hole 6 mm in diameter must also be drilled into which the leg from the old refrigerator will be screwed. In principle, you can do without it.
Further along the edges of the plastic sewer pipe it will be necessary to drill four more holes. Then, with the help of couplers, fans are mounted.
At the last stage of work, it remains only to connect the fans to the 12 V power supply, after which it is possible to fix the structure over the battery.
For details on how to make a useful home-made home-made piece of pipe and two fans with your own hands, see the video on the website.
