Description

投影裝置Projection device

本發明是有關於一種顯示裝置，且特別是有關於一種具有高導熱殼體的投影裝置。The present invention relates to a display device, and more particularly, to a projection device with a high thermal conductivity housing.

投影裝置為一種用以產生大尺寸畫面的顯示裝置，隨著科技技術的演進與創新，一直不斷的在進步。投影裝置的成像原理是將照明系統所產生的照明光束藉由光閥轉換成影像光束，再將影像光束通過投影鏡頭投射到投射目標物（例如：螢幕或牆面上），以形成投影畫面。A projection device is a display device used to generate large-scale images. With the evolution and innovation of science and technology, it is constantly improving. The imaging principle of the projection device is to convert the illumination beam generated by the illumination system into an image beam through a light valve, and then project the image beam to the projection target (such as a screen or a wall) through a projection lens to form a projection image.

近期投影裝置的發展，使用雷射光源（laser light source）作為激發光源，激發光源發射的激發光束照射到波長轉換裝置（例如螢光輪或螢光粉轉盤），波長轉換裝置上的波長轉換材料吸收激發光束後，產生波長不同的轉換光束。而上述的波長轉換裝置於激發過程中會產生熱量，因此會在波長轉換裝置周圍設有散熱裝置。In the recent development of projection devices, a laser light source is used as the excitation light source. The excitation beam emitted by the excitation light source is irradiated to a wavelength conversion device (such as a fluorescent wheel or a fluorescent powder turntable), and the wavelength conversion material on the wavelength conversion device absorbs the After the excitation beam, converted beams with different wavelengths are generated. The above-mentioned wavelength conversion device generates heat during the excitation process, so a heat dissipation device is provided around the wavelength conversion device.

在習知技術中，波長轉換裝置設置於風道中，風道中設有一個空氣與液體的熱交換器，風道中循環的空氣與外來的水進行熱交換。除上述熱交換器外，也可在波長轉換裝置的殼體內設置熱交換器，將殼體內的熱量傳至外界散熱。然而，上述的散熱裝置除了因循環風道設計而造成風道體積較大之外，在風道中也需設有空氣與液體的熱交換器，也會增加組裝工序而增加組裝難度。In the prior art, the wavelength conversion device is arranged in an air duct, and an air-liquid heat exchanger is arranged in the air duct, and the air circulating in the air duct exchanges heat with external water. In addition to the above-mentioned heat exchanger, a heat exchanger may also be provided in the casing of the wavelength conversion device to transfer the heat in the casing to the outside for heat dissipation. However, in addition to the large volume of the air duct due to the design of the circulating air duct, the above-mentioned heat dissipation device also needs to be provided with an air-liquid heat exchanger in the air duct, which also increases the assembly process and increases the difficulty of assembly.

圖5為本發明另一實施例的部份投影裝置的示意圖。請參考圖5。本實施例所顯示的部份投影裝置100C類似於圖4所顯示的投影裝置100。兩者不同之處在於，在本實施例中，第一殼體140還包括多個散熱鰭片142，連接第一流道C1且位於容置空間E內。當光學元件150（螢光輪）產生熱時，部分的熱會以熱傳導的方式被第一流體F1直接帶走，但同時藉由散熱元件170將另一部分的熱以熱對流的方式帶到容置空間E內的空氣中，而容置空間E內的空氣所帶的熱將傳遞至多個散熱鰭片142，再由多個散熱鰭片142傳導至第一流體F1。如此一來，可進一步提升容置空間E中的熱對流效果，進而將提升散熱效果。FIG. 5 is a schematic diagram of a part of a projection apparatus according to another embodiment of the present invention. Please refer to Figure 5. Part of the projection apparatus 100C shown in this embodiment is similar to the projection apparatus 100 shown in FIG. 4 . The difference between the two is that, in this embodiment, the first housing 140 further includes a plurality of heat dissipation fins 142 , which are connected to the first flow channel C1 and are located in the accommodating space E. When the optical element 150 (fluorescent wheel) generates heat, part of the heat will be directly taken away by the first fluid F1 in the form of thermal conduction, but at the same time, another part of the heat will be brought to the container in the form of thermal convection by the heat dissipation element 170 In the air in the space E, the heat carried by the air in the accommodating space E will be transferred to the plurality of heat dissipation fins 142 , and then conducted to the first fluid F1 by the plurality of heat dissipation fins 142 . In this way, the heat convection effect in the accommodating space E can be further improved, thereby improving the heat dissipation effect.

Please refer to FIG. 6A and FIG. 6B . Part of the projection apparatus 100D shown in this embodiment is similar to the projection apparatus 100A shown in FIG. 3 .
