    • PROBLEM TO BE SOLVED: To provide an improved heat exchanger having a substantially reduced dead zone and low flow velocity region which cause significant fouling problems. SOLUTION: The heat exchanger has the dead zone and a residence region substantially minimized or removed. The heat exchanger comprises a floating tube sheet movable to the longitudinal direction with the expansion and contraction of a tube. A shell is joined to the end thereof with a conical member and the conical member is preferably joined to the shell at a certain distance along the length of the shell to form a shell expansion portion for improving a flow pattern in a tube end region. The tube has a sacrifice portion for allowing inexpensive and easy repair and replacement of a tube erosion portion with the minimum process interruption and thereby coping with the erosion of the tube. The axial flow of a fluid on the shell side avoids almost all problems on the vibration of the tube and suppresses the fouling at a high flow velocity. COPYRIGHT: (C)2004,JPO
    • 要解决的问题:提供一种具有大大减少的死区和低流速区域的改进的热交换器,其导致严重的结垢问题。 解决方案:热交换器具有死区和基本上最小化或去除的停留区。 该热交换器包括可沿着纵向方向移动的浮动管板,随着管的膨胀和收缩。 壳体的端部与圆锥形构件接合,并且锥形构件优选地沿着壳体的长度以一定距离连接到壳体,以形成用于改善管端部区域中的流动模式的壳体膨胀部分。 管具有牺牲部分,用于允许便宜且容易地修复和更换管道侵蚀部分,同时具有最小的过程中断,从而应对管的侵蚀。 外壳上的流体的轴向流动几乎避免了管的振动的所有问题,并以高流速抑制了结垢。 版权所有(C)2004,JPO

    • PURPOSE:To prevent air leakage between fins and a sheet metal and to obtain a dimension of high precision with respect to the height of a core formed by fins by disposing a plate between the sheet metal and fins of a heat exchanger and inserting a tube into the plate. CONSTITUTION:A hot water inlet pipe 2 is connected to a hot water tank 1, and a hot water outlet pipe 4 is connected to a hot water tank 3. A sheet metal 7 covers a hot water tank 5. A tube 8 inserted into the sheet metal 7 is connected to the hot water tank 5. Corrugated type fins 9 are loaded in the tube 8. The plate 11 covers almost the entire part of the sheet metal 7. The tube 8 is inserted into the plate 11, and the fins 9 are engaged with the plate 11 in a state of being pressed at the end portions thereof. Since the fins 9 are constantly pressed, air leakage between the fins and the sheet metal as shown by arrow can be prevented, and the height dimension of the core forming the fins can be determined by the plate 11. Hence, it is possible to improve the precision of the core height dimension.
    • 目的:为了防止翅片和金属板之间的空气泄漏,并且通过在热交换器的金属板和翅片之间设置板,并将管插入到板中,获得相对于由翅片形成的芯的高度的高精度的尺寸 碟子。 构成:热水入口管2连接到热水箱1,热水出口管4连接到热水箱3.金属片7覆盖热水箱5。 金属板7与热水箱5连接。波纹状散热片9装载在管8中。板11几乎覆盖金属片7的整个部分。管8插入板11中,翅片 9在其端部被按压的状态下与板11接合。 由于翅片9被恒定地按压,所以能够防止翅片和金属板之间的空气如箭头所示的空气泄漏,并且能够通过板11来确定形成翅片的芯体的高度尺寸。因此,可以提高 芯高度尺寸的精度。
