Abstract
The utility model relates to a projector. An internal circulation refrigeration heat radiation air flue is installed in the projector. A circuit chamber and a light path chamber are installed in the lower layer cabinet of the projector respectively. A heat radiation fan in the internal circulation refrigeration heat radiation air flue is installed on a projection lamp air cooling radiating fin located at the cooling air flow outlet of the circuit chamber or installed at the cooling air flow air inlet of the light path. A projector signal input socket plate is installed in a signal input plate sealing box. A power supply line and a signal line extending line go through a sealing hole and are connected with a circuit mainboard in the circuit chamber. An upper layer cabinet is an air flow cooling chamber of the internal circulation heat radiation air flue. A built-in air filtration element is installed between the cooling air flow outlet end in the internal circulation refrigeration heat radiation air flue and the cooling air flow inlet end. A base plate of a semiconductor refrigeration radiator is fixed on the upper layer cabinet cover. A sound absorbing material is pasted on the inner wall of the whole machine cabinet. The projector isolates the machine inner space from the machine outer space completely. The semiconductor refrigeration radiator is employed to cool the air flow in the totally-enclosed internal circulation refrigeration heat radiation air flue in the machine, and thus the whole machine obtains good heat radiation and keeps dust-free and clean inside. Uninterrupted running of the projector and no dust cleaning or maintenance inside the machine are achieved, and no-dust and clearness of the projection picture are kept.
Description
Technical field
This projector relates to projector equipment field, especially its totally-enclosed cabinet.
Background technology
Now the radiating mode utmost point of various popular projectors is unfavorable for the heat radiation, dustproof of machine intimate, the especially heat radiation of projector's display screen, light path etc., a dustproof difficult problem.In the projector of current trend; in machine, display screen is often operated in hot environment; and owing to having used the radiating elements such as multi-fan; open inner light path environment; thereby cause machine intimate to enter a large amount of dusts along with radiation air; as cleared up not in time, the not only unusual impact quality of watching, is also easy to cause occur in machine that heat dissipation wind channel obstructions, temperature rising, high temperature shutdown, short circuit, display screen reduction tenure of use even burn etc. fault or accident.The specialty that the maintenance of projector in routine use, cleaning dust etc. work is all compared, and the expense of safeguarding is also relatively costly, and in fact the user of a lot of projectors does not possess professional machine maintenance and maintainability, make projector use trouble the more.
Summary of the invention
