Abstract

The invention belongs to the technical field of thermoelectric conversion and discloses a projector cooling system with a fairing. The projector cooling system comprises a projector housing, thermoelectric conversion materials, a support, a direct-current fan, an electric energy storage module, a control module, cables and the fairing, wherein the thermoelectric conversion materials are inlaid in the inner side wall of the projector housing, the support is arranged on the outer side wall of the projector housing, the fairing is arranged on the support, the direct-current fan is arranged on the fairing, the thermoelectric conversion materials are connected with the electric energy storage module through corresponding cables, and the control module is connected with the electric energy storage module and the direct-current fan through corresponding cables. The projector cooling system is reasonable in design, simple in structure and capable of solving the problem that a projector bulb can not be protected under the condition of improper electric energy supply or improper manual operation of the projector bulb cooling system.

Description

technical field [0001] The invention belongs to the technical field of thermoelectric conversion, and specifically relates to a projector heat dissipation system with a fairing that utilizes the waste heat generated by projector bulbs to generate electricity, and then uses the electric energy for the bulb cooling fan. Background technique [0002] At present, projectors have been widely used in homes, offices, schools and entertainment venues. LCD (Liquid Crystal Display) liquid crystal projectors can be divided into liquid crystal panel projectors and liquid crystal light valve projectors. The former is the main product in the projector market. Polysilicon LCD panels are not resistant to high temperatures. Newer models are equipped with temperature sensors near the LCD panel. When the air inlet and dust filter are blocked and the airflow is not smooth, the temperature inside the projector will rise rapidly. Alarm and immediately cut off the light source circuit. Projector...
