1. A solar thermal collector comprising: a plurality of parallel vertical tubes, connected to each other by at least one upper horizontal tube and by one lower horizontal tube through which a heat carrying fluid flows,a glass surface that covers the parallel vertical tubes, the upper horizontal tube
1. A solar thermal collector comprising: a plurality of parallel vertical tubes, connected to each other by at least one upper horizontal tube and by one lower horizontal tube through which a heat carrying fluid flows,a glass surface that covers the parallel vertical tubes, the upper horizontal tube and the lower horizontal tube, anda dissipating device installed in an upper part of the solar thermal collector, said dissipating device including a thermostatic valve, a heat exchanger and a return pipe,wherein said thermostatic valve is housed in the upper horizontal tube, the thermostatic valve and the heat exchanger being connected by means of a pipe by way of an inverted U-shaped tube provided at a greater height than an inlet of said heat exchanger, such that, under normal working conditions for a solar power installation, energy losses due to the heat transfer by convection from the thermostatic valve to the heat exchanger are prevented. 2. A solar thermal collector according to claim 1, wherein said return pipe is connected to said lower horizontal tube. 3. A solar thermal collector according to claim 1, wherein said return pipe is connected to said upper horizontal tube by way of a U-shaped tub and and the return pipe comprises a portion provided at a lower height than the upper horizontal tube, in such a way that the U-shaped tube acts as a hydraulic lock for any heat transfer by convection, under normal working conditions for the solar power installation, the solar thermal collector being provided with a lateral inclination in relation to a horizontal plane. 4. A solar thermal collector according to claim 3 wherein the return pipe comprises an insulating sleeve in such a way that it interrupts the heat transfer by conduction between the heat exchanger and the upper horizontal tube. 5. A solar thermal collector according to claim 3 wherein said lateral inclination is at least 1 degree. 6. A solar thermal collector according to claim 1, wherein the thermostatic valve is of the four-port type. 7. A solar thermal collector according to claim 1, wherein said thermostatic valve is thermally insulated at least partially. 8. A solar thermal collector according to claim 1, wherein said thermostatic valve allows the passage of the heat carrying fluid to the heat exchanger when the heat carrying fluid reaches a pre-set temperature. 9. A solar thermal collector according to claim 1, wherein a manually operated air vent is provided at a highest point of the inverted U-shaped tube. 10. A solar thermal collector according to claim 1, wherein said dissipating device is housed in a chamber that is separated from the rest of the solar panel by means of a dividing wall. 11. A solar thermal collector according to claim 10, wherein said chamber has air grilles on at least two walls thereof.
