Detailed Description
In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. Several embodiments of the invention are presented in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for purposes of illustration only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 and 2, an embodiment of the present invention provides a heat dissipation structure for a projector, including a housing 10, an air suction fan 20 disposed in the housing 10, a heat absorption air guide plate 30 disposed on one side of the air suction fan 20, and an exhaust fan 40 disposed at an air outlet end of the heat absorption air guide plate 30, where the heat absorption air guide plate 30 includes a connection heat absorption portion 31 and a curved air guide portion 32 connected to the connection heat absorption portion, an air outlet end of the air suction fan 20 is disposed toward the curved air guide portion 32, and air holes 11 are disposed at positions of the housing 10 corresponding to the air suction fan 20 and the exhaust fan 40.
When the heat dissipation structure for the projector works, the heat absorption portion 31 is connected to absorb heat from the projection lens module 100 and transmit the heat to the curved air guiding portion 32, the air suction fan 20 sucks and blows external cold air to the curved air guiding portion 32, meanwhile, the heat on the curved air guiding portion 32 is guided to the exhaust fan 40, hot air is exhausted from the air holes 11 through the exhaust fan 40, and the heat absorption and air guiding functions of the heat absorption air guide plate 30 accelerate the heat exhaust efficiency.
Specifically, the heat absorbing and air guiding plate 30 may be made of aluminum alloy to achieve a heat dissipation effect.
Referring to fig. 3, a difference between the second embodiment and the first embodiment of the heat dissipation structure for a projector according to the present invention is that, in the second embodiment, the heat absorption air guiding plate 30 further includes a grid plate portion 33 disposed in the middle of the curved air guiding portion 32, so as to increase the heat dissipation area of the heat absorption air guiding plate 30 and improve the heat dissipation efficiency.
Specifically, in the present embodiment, the air suction fan 20 and the heat absorption air guide plate 30 are disposed at an interval, so that when the air suction fan 20 exhausts air toward the heat absorption air guide plate 30, other air inside the casing 10 is driven to enter the air guide area of the heat absorption air guide plate 30 by using a siphon effect, thereby improving the heat dissipation effect of the whole projection, and meanwhile, the air discharge fan 40 is connected to the heat absorption air guide plate 20 in an abutting manner, so that heat in the air guide area of the heat absorption air guide plate 30 is directly guided to the air discharge fan 40 and exhausted by the air discharge fan 40, thereby improving the heat dissipation efficiency.
Specifically, in the present embodiment, the suction fan 20 is disposed at a corner of the housing 10. It can be understood that, by such a position arrangement, more ventilation holes 11 are formed at the position of the casing 10 corresponding to the suction fan 20, so as to improve the suction efficiency.
Specifically, in this embodiment, the power of the exhaust fan 40 is greater than the power of the suction fan 20, so that the suction force of the exhaust fan 40 guides the flow direction of the air, and the heat dissipation effect is improved.
The above-mentioned embodiments only represent several embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention.
