Description

A liquid-type PVT collector {Liquid Type Photohvoltaic-thermal Collector}

More particularly, the present invention relates to a liquid type PVT collector, and more particularly, to a solar collector that collects electric energy and heat sources, which are necessary energy for living, by collecting electric power of a solar light source and collecting heat energy, Lt; RTI ID = 0.0 > PVT < / RTI >

Generally, solar power generation includes solar power generation that converts sunlight or solar energy to electric energy, and solar heat collection power for heating or warming the solar light source after collecting the solar heat source. Various photovoltaic (PV) modules have been developed and used.

However, the PV module generates heat during the electric production process, thereby raising the temperature of the PV module, thereby deteriorating the electricity production efficiency. That is, in the case of the crystalline solar cell, only 12 to 16% of the energy input from the sun is used for power generation, so that the efficiency of utilization of solar energy is considerably low and all the remaining energy is consumed as heat, There is a problem in that the temperature of the cell is increased and the electric conversion efficiency is reduced when the electric energy is changed due to the temperature rise due to the cell characteristics.

Therefore, in the case of the photovoltaic power generation module, the waste heat is discharged after the structure for ventilating the heat is provided on the rear side, and the electric performance of the system is improved as the temperature of the photovoltaic power generation module is lowered.

In this background, a PVT (photo-voltaic-thermal) composite module (PVT) module, which can efficiently utilize the heat generated during the electric production process of the PV module to utilize the solar and solar heat simultaneously, Has been developed and used.

As a prior art disclosed in relation to the solar / thermal composite collection module, Korean Patent Laid-Open Publication No. 44112 (May 31, 2013) discloses a photoelectric conversion unit for generating electric energy from sunlight, A heat pipe attached to the lower end of the heat collecting plate and collecting the heat through solar light having a wavelength transmitted through the photoelectric conversion unit, a heat pipe connected to the heat collecting plate and transferring the heat energy collected from the heat collecting plate to the outside, And the solar battery module is constructed such that the photoelectric conversion unit, the heat collecting plate, and the heat pipe are drawn into the mold, thereby performing electro-optical conversion simultaneously with the heat collection and maximizing energy utilization efficiency have.

However, in the case of the above conventional technology, since a thermally conductive adhesive is used for attaching the heat collecting plate to the photoelectric conversion unit which is a PV module, it is difficult to manufacture the heat collecting plate by attaching the heat collecting plate to the PV module. And the heat transfer performance toward the heat collecting plate is remarkably deteriorated.

In addition, in the case of the heat pipe joined to the heat collecting plate, since the ultrasonic welding is performed so that only a part of the circumference of the heat pipe for transmitting heat energy to the outside is externally welded to the surface of the heat collecting plate, the heat pipe welded to the thin heat collecting plate The quality of the heat collecting plate is lowered due to the bending of the heat collecting plate. In addition, since the non-smooth heat collecting plate is attached to the PV module, the mutual bonding state is poor and the function of the heat collecting plate is deteriorated and the heat pipe is simply bonded to the heat collecting plate, And the thermal efficiency is low due to the low heat transfer efficiency.
