U-Pipe Collector

U-Pipe Collector


U-Pipe collector's:

The collector consists of a number of copper tubes in the form of a U-shaped, and these tubes are connected to two copper headers surrounded by each copper tube with an aluminum reflector to increase the thermal conductivity of the device and finally- the copper tube collected with aluminum incubator within a vacuum tube, and this installation works as a thermal trap so that it captures incoming solar radiation in directs it towards the inner copper tube, and prevents it's reflection outside the glass tube.

U-Pipe work Principle:

The vacuum tubes absorb energy from the sun and convert them into heat, so the aluminum sheets absorb them inside the tube and transfer this heat to the copper tubes and thus the liquid that runs into the copper tubes by means of a circulation pump that transfer this heat, and transfer it to the hot water tank or to other heating systems.

Advantages of U-Pipe Solar Pickup:

The advantages of U-Pipe make it one of the best parts in the world, in all seasons, for the following reasons:

1- High return, which reaches more than 90%

2- The relatively small area, which is equivalent to a third of the area needed from flat plate, to give the same thermal power.

3- Ease of installation on different engineering surfaces with angles from (0-90) degrees, and it can also be installed with vertical position parallel to the front walls of the building.

4- High reliability in operation, as the water flow is within the copper tubes and not the glass directly, which gives a great safety factor in the event of breaking one or more glass tubes until it is replaced.

5- This system can be operated with a pressure of up to 10 bars, which makes it suitable for supporting the heating circuits, factory circuits and all other circuits that use a relatively high operating pressure, knowing that the experimental pressure of these devices is 12 bars.
