Description

Technical Field

[0001] The utility model relates to the technical field of projector heat dissipation structures, in particular to an internal circulation heat exchange heat dissipation structure for a projector. Background Art

[0002] With the development of the economy and society, people's living standards have gradually improved, and projectors are becoming more and more common around us. A projector is a device that can project images or videos onto a screen. It is widely used in homes, offices, schools, and various entertainment venues. A projector will generate a lot of heat during use. If the heat is not dissipated in time, the internal temperature will rise, affecting the projection effect and even damaging the equipment. Good heat dissipation can protect the internal components of the projector and avoid shortening its service life due to overheating. The heat dissipation methods of the projector include natural heat dissipation, fan heat dissipation, liquid cooling, etc.

[0003] The existing authorization announcement number CN 218068553 U discloses a single-chip LCD projector and projector. The single-chip LCD projector includes a housing, an optical assembly, and a heat dissipation assembly. The optical assembly includes a light source, a first lens, an LCD screen, and a second lens, which are arranged in sequence along the light propagation direction. The first lens is disposed in a receiving cavity of the housing and divides the receiving cavity into a first cavity and a second cavity. The LCD screen and the second lens are disposed in the first cavity, and an air flow channel is formed between the first lens and the second lens. The heat dissipation assembly includes a first fan and a first heat exchanger and a second heat exchanger mounted on opposite side walls of the first cavity. The first fan is located between the first heat exchanger and the second heat exchanger. The first fan has a first air intake, a second air intake, and a first air exhaust. The first air intake faces the first heat exchanger, the second air intake faces the second heat exchanger, and the first air exhaust is connected to the air inlet of the air flow channel. The single-chip LCD projector of the utility model has good heat dissipation performance, but this heat dissipation is specifically for the LCD screen and cannot dissipate heat for the entire device, resulting in a single heat dissipation function.

[0004] Therefore, the present invention proposes an internal circulation heat exchange heat dissipation structure for a projector to dissipate heat comprehensively from the projector and ensure that the projector works stably for a long time, so as to solve such problems. Utility Model Content

[0023] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0024] Please refer to Figure 1-Figure 4The present invention proposes an internal circulation heat exchange and heat dissipation structure for a projector, comprising a front top cover 1, a heat dissipation fan 4 is installed on the top surface of the front top cover 1, which can dissipate heat to the bottom of the front top cover 1, a projector frame 9 is installed at the bottom of the front top cover 1, and a projection mechanism 5 is installed on the front side of the projector frame 9. When working, the projection mechanism 5 projects an image on a plane. After the projection mechanism 5 works, the temperature of the middle part will rise, and it is necessary to dissipate heat in a concentrated manner. A bottom radiator 16 is installed at the bottom of the projector frame 9, and wind can be sucked in from the bottom through the bottom radiator 16. The heat dissipated in the middle of the projector frame 9 is taken away by the secondary hot surface radiator 17 and leaves the projector. A second cold surface radiator 6 and a first hot surface radiator 2 are installed on both sides of the projector frame 9. External wind can enter from the outside of the first cold surface radiator 3 and the second hot surface radiator 8. Under the action of the second cold surface radiator 6 and the first hot surface radiator 2, the external wind continuously enters the interior of the projector located in the projector frame 9, forming a circular circulation air duct in the middle of the projector frame 9, adding an internal heat exchange cycle for heat dissipation in the middle of the projector frame 9.

[0025] A primary heating surface radiator 15 and a secondary heating surface radiator 17 are installed on the rear side of the projector frame 9, and the secondary heating surface radiator 17 and the primary heating surface radiator 15 are installed on both sides of the rear cover 7 respectively. The projector light source 14 is installed in the middle of the primary heating surface radiator 15 and the secondary heating surface radiator 17. When the projector is in use, the projector light source 14, as the core structure of the projector, will emit a large amount of heat. The setting of the primary heating surface radiator 15 and the secondary heating surface radiator 17 can dissipate heat for the projector light source 14 in a targeted manner and protect the core structure.

[0026] In this embodiment, a first cold surface radiator 3 and a second hot surface radiator 8 are installed on both sides of the projector frame 9, a second cold surface radiator 6 and a first hot surface radiator 2 are installed on the outside of the first cold surface radiator 3 and the second hot surface radiator 8, a projection mechanism 5 is installed on the front side of the projector frame 9, a lens 11 and a projector light source 14 are installed on the rear side of the projector frame 9, and the lens 11 and the projector light source 14 are connected by a light funnel 18. When in use, the first hot surface radiator 2 is working. Under the action of the first hot surface radiator 2, the outside wind enters the middle part of the first hot surface radiator 2 and the projector frame 9 from the first cold surface radiator 3. The wind entering the middle part of the projector frame 9 joins the internal circulation air duct, which is used for cooling the projector frame 9. The middle part of the projector frame 9 is heat-dissipated. After the second cold surface radiator 6 works, the wind entering the middle part of the projector frame 9 from the second hot surface radiator 8 is also added to the internal circulation air duct. The top and bottom of the projector frame 9 are equipped with a cooling fan 4 and a bottom radiator 16. After the cooling fan 4 works, the wind can enter the middle part of the projector frame 9 from the outside of the bottom radiator 16. The projector light source 14 and the lens 11 are installed at the rear part of the projector frame 9 as the core structure of the projector. The secondary hot surface radiator 17 and the main hot surface radiator 15 are used to dissipate heat therefrom. At the same time, the wind in the internal circulation air duct in the middle part of the projector frame 9 will flow out from the middle part of the secondary hot surface radiator 17 and the main hot surface radiator 15 to dissipate heat for the projector light source 14.

[0027] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
