Description

熱交換裝置Heat exchange device

本發明係關於一種熱交換裝置,尤其是一種用於氣液熱交換的熱交換裝置。The invention relates to a heat exchange device, especially a heat exchange device used for gas-liquid heat exchange.

一般的鍋爐、焚化爐……等因運作而產生大量的高溫廢氣,而這些高溫廢氣通常還必須經過適當的降溫處理,才能排放於大氣環境中,如此才能符合環保的要求。而在前述高溫廢氣的降溫處理過程中,有些業者為了能充分地再利用該高溫廢氣,會應用於熱交換裝置的設施。習知的熱交換裝置具有一中空管體及位於該中空管體內的數個導熱管,該導熱管的外周具有數個鰭片,該數個導熱管的一端凸伸於一儲水槽內;據此,當高溫廢氣進入該中空管體後,其高溫熱能可以經由該數個導熱管傳導至該儲水槽,以期可以提升該儲水槽內的水液溫度。類似於該習知的熱交換裝置的一實施例已揭露於中華民國公告第472864號「廢棄氣體的熱能回收裝置(二)」專利案當中。General boilers, incinerators, etc. generate a large amount of high-temperature exhaust gas due to operation, and these high-temperature exhaust gas usually must be properly cooled to be discharged into the atmospheric environment, so as to meet the requirements of environmental protection. In the process of reducing the temperature of the high-temperature exhaust gas mentioned above, in order to fully reuse the high-temperature exhaust gas, some manufacturers will apply it to the facilities of the heat exchange device. The conventional heat exchange device has a hollow tube body and a plurality of heat conduction tubes located in the hollow tube body, the outer periphery of the heat conduction tube has a plurality of fins, and one end of the heat conduction tubes protrudes into a water storage tank According to this, when the high-temperature exhaust gas enters the hollow pipe body, its high-temperature thermal energy can be conducted to the water storage tank through the heat transfer tubes, in order to increase the temperature of the water in the water storage tank. An example of a heat exchange device similar to the conventional one has been disclosed in the patent case of the Republic of China Announcement No. 472864 "Thermal Energy Recovery Device for Waste Gas (2)".

上述習知的熱交換裝置,該導熱管大多係以銅或鋁…等高傳熱性的材質所製成,且該導熱管的外表面較為平整,使得高溫廢氣與該導熱管的接觸面積較小。然而,為了使其熱交換效果提昇,通常會使高溫廢氣停留在該導熱管處的時間拉長,如此,將會減緩該中空管體內之高溫廢氣的流動速度,使高溫廢氣進入該中空管體時容易形成堵塞,進而導致熱交換效果不佳。In the above-mentioned conventional heat exchange device, most of the heat pipe is made of high heat transfer materials such as copper or aluminum, etc., and the outer surface of the heat pipe is relatively flat, so that the contact area of the high temperature exhaust gas and the heat pipe is relatively small. However, in order to improve the heat exchange effect, the high-temperature exhaust gas usually stays at the heat pipe for a longer period of time, so that the flow rate of the high-temperature exhaust gas in the hollow tube body will be slowed down, so that the high-temperature exhaust gas enters the hollow The tube body is easy to form a blockage, which leads to poor heat exchange effect.

有鑑於此,習知的熱交換裝置確實仍有加以改善之必要。In view of this, the conventional heat exchange device does still need to be improved.

為解決上述問題,本發明的目的是提供一種熱交換裝置,係可以避免高溫廢氣進入中空管體時形成堵塞者。In order to solve the above-mentioned problems, the object of the present invention is to provide a heat exchange device, which can prevent high-temperature exhaust gas from entering into the hollow pipe body to form a blocker.

本發明的次一目的是提供一種熱交換裝置,係可以提升該熱交換裝置之結構強度者。The next object of the present invention is to provide a heat exchange device that can increase the structural strength of the heat exchange device.

本發明的又一目的是提供一種熱交換裝置,係可以增加導流順暢性者。Another object of the present invention is to provide a heat exchange device that can increase the smoothness of the flow guide.
