Description
本發明係關於可切換風道的冷卻裝置，以及具有該可切換風道的冷卻裝置的投影機裝置。The present invention relates to a cooling device for a switchable air duct, and a projector device having the cooling device of the switchable air passage.
現行的電子裝置，例如投影機、背投式電視、光碟機、電腦主機等，其內部皆須配置冷卻裝置來冷卻其操作期間所產生的熱。除了投影裝置的體積為一主要議題外，其他的議題，如散熱系統，亦是各廠商努力改善的目標。一部投影機之使用模式又有壁(天花板)掛式模式和桌放式兩種模式。設若投影機於桌放模式時其面對桌面的殼體面為A面，則當此投影機於壁(天花板)掛模式時該A面則朝向天花板。也就是說，於此兩模式下的投影機，是成180度的翻轉關係。Current electronic devices, such as projectors, rear projection televisions, optical disk drives, computer mainframes, etc., are internally equipped with cooling devices to cool the heat generated during their operation. In addition to the volume of the projection device is a major issue, other issues, such as the cooling system, are also the goal of various manufacturers to improve. The projector uses a wall (ceiling) hanging mode and a table-mounted mode. If the projector faces the desktop surface of the desktop when the projector is in the table mode, the A side faces the ceiling when the projector is in the wall (ceiling) hanging mode. That is to say, the projector in the two modes is in a 180 degree flip relationship.
投影機目前常用的燈源為高壓汞燈(mercury lamp)。現有之高功率的燈(>350W)對燈溫的規格較嚴；特別是燈芯溫度的上、下平衡的規格。由於燈芯有熱對流(convection)的物理現象，且熱空氣較輕會往上流動，因此造成燈芯的上方溫度會比下方溫度高。於壁(天花板)掛模式和桌放模式下，高熱點位置會隨著使用模式而改變。The lamp source commonly used in projectors is a high pressure mercury lamp. The existing high-power lamps (>350W) have stricter specifications on the lamp temperature; in particular, the upper and lower balance specifications of the wick temperature. Since the wick has a physical phenomenon of heat convection, and the hot air flows lightly upward, the temperature above the wick is higher than the temperature below. In the wall (ceiling) hanging mode and the table placement mode, the high hotspot position changes depending on the usage mode.
目前超過350W燈芯的投影機，其風道設計大都是使用兩個風道和兩個風扇，這樣不但成本高，所佔的空間也大。相關創作的相關前案，可參考例如日本國專利申請案JP10-1-6307公開案，該案具有一送風方向改變元件23，以便將冷卻氣流送往燈芯的高溫區。At present, projectors with more than 350W wicks are designed with two air ducts and two fans. This is not only costly but also takes up a lot of space. For a related example of the related art, reference is made to the publication of Japanese Patent Application No. JP 10-1-6307, which has an air supply direction changing element 23 for delivering a cooling airflow to a high temperature zone of the wick.
為了維持上方、下方燈溫的平衡，以符合規格，是有需求開發一種單一風道、單一風扇，且可以隨著壁(天花板)掛式和桌放式的選擇，而自動切換風道的機構。In order to maintain the balance of the upper and lower lamp temperatures, in order to meet the specifications, there is a need to develop a single air duct, a single fan, and can automatically switch the air duct mechanism with the choice of wall (ceiling) hanging and table-mounted. .

The first state of the gate 104 causes the cooling airflow to pass through the first air passage (the upper passage in FIG. 3), and the second state of the gate 104 causes the cooling airflow to pass through the second air passage (the upper passage in FIG. 4).
亦即，當該投影機裝置10以一第一情形運作時，該重力式切換裝置(109,104,107)處於第一狀態，該吹嘴105裝置所輸送的冷卻氣流通過該第一風道吹向該燈芯102的一第一高溫區，當該投影機裝置10以一第二情形運作時，該重力式切換裝置(109,104,107)處於第二狀態，該吹嘴105裝置所輸送的冷卻氣流通過該第二風道吹向該燈芯102的一第二高溫區，其中該第二高溫區與第一高溫區分別位於該燈芯的不同側。That is, when the projector device 10 is operated in a first situation, the gravity switching device (109, 104, 107) is in a first state, and the cooling airflow delivered by the nozzle 105 device is blown toward the wick through the first air passage. a first high temperature zone of 102, when the projector device 10 is operated in a second condition, the gravity switching device (109, 104, 107) is in a second state, and the cooling airflow delivered by the nozzle 105 device passes through the second wind The track is blown to a second high temperature zone of the wick 102, wherein the second high temperature zone and the first high temperature zone are respectively located on different sides of the wick.
