Abstract
The utility model provides a finned pipe type heat exchanger. A U-shaped pipe type heat exchanger which is arranged in a vacuum chamber of a vacuum hot water boiler is replaced with the fixed finned pipe type heat exchanger. The fixed finned pipe type heat exchanger comprises fins which are welded on the wall of a heat exchanging pipe, and the fixed finned type heat exchanger is fixed in the vacuum chamber. The finned pipe type heat exchanger can effectively utilize the space of the vacuum chamber. The fins of the heat exchanging pipe can enlarge the heat transfer area, increasing heat exchanging effect, and reducing the number of heat exchanging pipes. Moreover, the materials of the heat exchanging pipe are changed to ordinary steel instead of stainless steel, thus production cost of the heat exchanger is greatly reduced, the size of the boiler is reduced and manufacturing technology is simplified.
Description
Technical field
The utility model relates to the built-in heat transmission equipment technical field of vacuum hot water boiler, particularly a kind of fin tube type heat exchanger.
Background technology
In the vacuum chamber of vacuum hot water boiler, be fixed wtih U-shaped tubular type stainless heat exchanger with flange, be connected with flange with vacuum chamber and water-in and water-out header, can dismantle, working strength required during connection is high, and easily produces leakage.
The space of vacuum chamber is square, and U-shaped tubular type stainless heat exchanger is because of tube sheet and pressure-bearing condition, and the bending radius that crooked pipe need to be certain, thereby needs during fabrication the mould bend pipe of different curvature; The space of vacuum chamber is square simultaneously, and the shape of U-shaped like this pipe heat exchanger reduces the effective rate of utilization of vacuum chamber, causes the utilization not yet in effect of the very large space of vacuum chamber; Be the requirement of the heat exchange amount that satisfies heat exchanger, the space of vacuum chamber again must be enough greatly, and also so that the vacuum hot water volume is large, it is more to cause steel to expend, and cost is higher, complex manufacturing.
Summary of the invention
The utility model provides a kind of fin tube type heat exchanger, by the U-shaped pipe heat exchanger in the vacuum chamber of vacuum hot water boiler is replaced with fixedly fin tube-sheet heat exchanger, fixedly the fin tube-sheet heat exchanger is included on its heat exchange tube wall and is welded with fin, and described fixedly fin tube-sheet heat exchanger is fixed in the vacuum chamber.Effectively utilized the space of vacuum chamber, heat exchanger tube can increase heat transfer area with fin, strengthens heat transfer effect, reduce the heat exchanger tube number, material with heat exchanger tube changes ordinary steel into by stainless steel in addition, greatly reduces the heat exchanger production cost, has dwindled boiler volume and has reduced manufacturing process.
For achieving the above object, the technical solution of the utility model is:
A kind of fin tube type heat exchanger, U-shaped pipe heat exchanger in the vacuum chamber of vacuum hot water boiler is replaced with fixedly fin tube-sheet heat exchanger 3, fixedly fin tube-sheet heat exchanger 3 is included on its heat exchange tube wall 1 and is welded with fin 2, and described fixedly fin tube-sheet heat exchanger 3 is fixed in the vacuum chamber 4.
Described fixedly fin tube-sheet heat exchanger 3 is that the modes that are fixed in the vacuum chamber 4 link to each other with heat exchanger tube 6 on the vacuum chamber rear wall 5 for a fixing side pipe case of fin tube-sheet heat exchanger is welded on, fixedly the bobbin carriage of the opposite side band pass partition 7 of fin tube-sheet heat exchanger is welded in vacuum chamber antetheca 8, and be conducted with water inlet pipe 9 and outlet pipe 10, so fixedly fin tube-sheet heat exchanger 3 with boiler body by the original split type integral type that become.
Described fixedly fin tube-sheet heat exchanger 3 adopts the ordinary steel material.
Change U-shaped pipe heat exchanger into fixedly fin tube-sheet heat exchanger 3, and be weldingly fixed in the vacuum chamber 4, at heat exchange tube wall 1 welding fin 2, to increase heat exchange area, strengthen heat transfer effect, reduce the quantity of heat exchanger tube, effectively utilize the space of vacuum chamber, and can reduce the boiler body volume.
Description of drawings
Fig. 1 represents structural representation of the present utility model.
Fig. 2 represents the horizontal schematic diagram of welding fin on the heat exchange tube wall of the present utility model.
Fig. 3 represents vertical schematic diagram of welding fin on the heat exchange tube wall of the present utility model.
The specific embodiment
The below is described further the utility model via accompanying drawing:
Such as accompanying drawing 1, Fig. 2 and shown in Figure 3, fin tube type heat exchanger, U-shaped pipe heat exchanger in the vacuum chamber of vacuum hot water boiler is replaced with fixedly fin tube-sheet heat exchanger 3, fixedly fin tube-sheet heat exchanger 3 is included on its heat exchange tube wall 1 and is welded with fin 2, and described fixedly fin tube-sheet heat exchanger 3 is fixed in the vacuum chamber 4.Described fixedly fin tube-sheet heat exchanger 3 is that the modes that are fixed in the vacuum chamber 4 link to each other with heat exchanger tube 6 on the vacuum chamber rear wall 5 for a fixing side pipe case of fin tube-sheet heat exchanger is welded on, fixedly the bobbin carriage of the opposite side band pass partition 7 of fin tube-sheet heat exchanger is welded in vacuum chamber antetheca 8, and be conducted with water inlet pipe 9 and outlet pipe 10, so fixedly fin tube-sheet heat exchanger 3 with boiler body by the original split type integral type that become.Described fixedly fin tube-sheet heat exchanger 3 adopts stainless steel material.The utility model is fast because of the system water flowing velocity, and unsuitable fouling is so need not overhaul and clean, be welded with fin 2 on the heat exchange tube wall 1, not only increase heat exchange area, comparable light pipe increases 2～10 times, and can promote the turbulent flow of fluid, so the ratio of heat transfer coefficient light pipe can improve 1～2 times.Because the enhancing of heat-transfer capability and the heat-transfer area of unit volume strengthen, so can use than when finishing same thermic load than the education and correction for juvenile offenders number with light pipe, owing to added fin 2, vacuum chamber 4 is more effectively used, and reduce the volume of vacuum chamber 4, the volume of boiler just can reduce thereupon like this, and structure is compacter, and metal wastage is reduced.Adopt fin 2 that the mean temperature difference of medium and wall is reduced, alleviated fouling.Change stainless steel material into ordinary steel, decrease cost.
