Heat transfer unit and solar cell apparatus having thereof

The present invention provides a heat transfer unit capable of utilizing high-efficiency energy and a solar cell apparatus including the same. According to an embodiment of the present invention, the heat transfer unit comprises: an accommodation member on which an object to be cooled is mounted and through which a fluid flows; a pin member formed to protrude from the accommodation member to induce turbulent flow or vertical flow of the fluid; and a passing member connected with the accommodation member and transferring the fluid emitted from the accommodation member to an object to be increased in temperature. According to other embodiments of the present invention, the solar cell apparatus comprises: a heat transfer unit; and a solar cell panel which is the object to be cooled to be mounted on the accommodation member. 본 발명의 일 실시예에 따른 열전달유닛은 피냉각체가 안착되고, 유체가 유출입되는 수용부재, 상기 수용부재에 돌출되게 형성되어 유체의 난류 또는 와류 유동을 유도하는 핀부재 및 상기 수용부재와 연결되며, 상기 수용부재에서 배출되는 유체를 피승온체로 전달하는 패싱부재를 포함할 수 있다. 그리고, 본 발명의 다른 실시예에 따른 태양전지장치는 상기 열전달유닛 및 상기 수용부재에 안착되는 피냉각체인 솔라셀패널을 포함할 수 있다.
