Abstract

The invention discloses an embedded type heat dissipation system of a projector and belongs to the technical field of thermoelectric conversion. The embedded type heat dissipation system comprises a projector outer cover, thermoelectric conversion materials, a support, a direct-current fan, an electric energy storage module, a control module and cables. The thermoelectric conversion materials are embedded in the inner side wall of the projector outer cover, the support is arranged on the outer side wall of the projector outer cover, the direct-current fan is arranged on the support, the thermoelectric conversion materials are connected with the electric energy storage module through the cables, and the control module is respectively connected with the electric energy storage module and the direct-current fan through the cables. The embedded type heat dissipation system is reasonable in design, simple in structure and capable of solving the problem of electric energy supplying of a projector lamp bulb heat dissipation system and the problem of projector lamp bulb protection when manual operation is not correct.

Description

technical field [0001] The invention belongs to the technical field of thermoelectric conversion, and specifically relates to an embedded projector heat dissipation system that utilizes waste heat generated by projector bulbs to generate power, 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. Projectors have very str...
