    蜂窩緊湊結構螺旋板換熱器

        高效、緊湊換熱器是目前最有發展前途的新型換熱設備,綜合吸納了板式、板翅式及螺旋板換熱器的優點,開發出一種新型蜂窩緊湊結構螺旋板換熱器,詳細介紹了該換熱器的結構特點、優越性及應用場合,便于更好地推廣應用。
    Efficient and compact heat exchanger is one of the most promising new type of heat exchange equipment, comprehensive absorbed plate, the plate heat exchanger and the advantages of the spiral plate heat exchanger, developed a new type of compact cellular structure of the spiral plate heat exchanger, the structure characteristics of the heat exchanger is introduced, advantages and applications, to facilitate better popularization and application.
    蜂窩緊湊結構螺旋板換熱器,它是采用和板式換熱器傳熱板相似的帶有壓槽(坑)的1mm薄金屬板取代螺旋板換熱器的螺旋板,用薄板上密布的凹坑取代稀疏的定位柱,構成蜂窩巢狀內膽的新型蜂窩螺旋板換熱器。
    該換熱器的結構綜合了板式、板翅式和螺旋板式3種換熱器的優點,擯棄其缺點,通過結構集成及優化而成。它是一種可用于高壓介質、結構緊湊、金屬消耗量低、傳熱高效、制造也不太復雜的高效緊湊換熱器。
    Cellular compact structure of the spiral plate heat exchanger, it is to use similar with pressure groove and the plate heat exchanger heat transfer plate (pit) of 1 mm sheet metal instead of the spiral plate heat exchanger of helical plate, sheet in the pit to replace sparse positioning column, constitutes a new type of honeycomb cellular nests bladder spiral plate heat exchanger.
    Structure integrated with plate heat exchanger, plate heat exchanger and spiral plate heat exchanger, the advantages of abandon its shortcomings, by structure integration and optimization. It is a new medium can be used for high, compact structure, low metal consumption and heat transfer efficiency, compact high efficiency heat exchanger manufacturing also not too complicated.
    蜂窩換熱器的結構特點
    對板式、板翅式及螺旋板式等換熱器的結構性能綜合分析可知,從承受介質壓力的能力看, 板式、板翅式換熱器傳熱元件(板片)遠遠優于螺旋板換熱器的內件(螺旋板) ;螺旋板換熱器的筒狀外殼又遠遠優于板式換熱器的厚平板外殼;從內件的傳熱系數及單位傳熱面積金屬消耗量來看,板式、板翅式換熱器的內件遠優于螺旋板換熱器的內件;從2種換熱器介質流程、溫差及處理量等方面,螺旋板換熱器總體結構又優于板式、板翅式換熱器的總體結構。
    such as performance, a comprehensive analysis from the medium pressure ability, plate, plate fin heat exchanger heat transfer components (plate) is much better than the screw plate heat exchanger in a spiral plate (); Tubular shell of spiral plate heat exchanger is much better than the plate heat exchanger of thick plate shell; From the internal parts of heat transfer coefficient of heat transfer and unit area of metal consumption, plate, plate fin heat exchanger in the internal parts of a far better than the screw plate heat exchanger; From 2 medium and processing process, the temperature difference of heat exchanger, spiral plate heat exchanger and overall structure is superior to the plate, the overall structure of the plate-fin heat exchanger.
    在分析比較的基礎上,提出了這種新型結構換熱器———蜂窩緊湊螺旋板換熱器。
    換熱器外部結構采用普通螺旋板式換熱器的圓筒體結構,內部用作傳熱面的螺旋板改用與板式換熱器傳熱板相似的具有壓槽(坑)的薄不銹鋼傳熱板卷制而成,構成一種宏觀上看起來是螺旋板換熱器,從傳熱面看卻是蜂窩(巢)狀緊湊結構,既像板式又像板翅式的緊湊式換熱器該換熱器的傳熱板在高壓介質的作用下,通過密布的凹坑的凸出高度的支撐,相鄰兩板緊緊壓在一起,凹坑起了定距柱的作用,但此“定距柱”并不需要焊接,沖壓的數量也沒有限制。眾所周知,多支承平板承受均布載荷的介質壓力的能力與撐點的間距的平方成反比,密布支撐點的薄板可以承受很高的介質壓力。
    External heat exchanger structure using common cylinder structure of the spiral plate heat exchanger, internal used for spiral plate heat transfer surface to similar to plate heat exchanger heat transfer plate has a pressure tank (pit) of thin stainless steel heat transfer plate coiling, constitute a macro seems to be on the spiral plate heat exchanger, look from the heat transfer surface is the cellular (nests) shape compact structure, both as compact like a plate heat exchanger and plate heat exchanger heat transfer of the heat exchanger plate under the action of high pressure medium, by gathering the bulging height of pit support, two adjacent plate tightly pressed together, pits have played a role in column spacing, but the "distance column" does not need welding, there is no limit to the number of stamping. As we all know, the more support plate under uniform load and the power of the medium pressure is inversely proportional to the square of the distance of supporting points, gathering point of sheet can be medium under high pressure.
    多支撐點的凹坑將圓筒狀的內、外壓壓力容器轉化為以支撐點間距為尺寸的多腔體承壓結構,像板翅式換熱器的蜂巢中的一個個蜂窩,從而可以具有板翅式換熱器的結構緊湊、傳熱效率高的優點。螺旋板換熱器有足夠厚度的圓柱形外殼,承受內壓能力是很強的,將所有螺旋板包扎在一起,所以在支撐點處的凹坑與相鄰板之間并不需要焊接,從而克服了板翅式換熱器各板翅之間需要釬焊的缺點,大大減少了加工費用。在設備大型化方面也比板翅式換熱器及板式換熱器更為有利。
    More strong point of pit will cylinder into the internal and external pressure of pressure vessel with anchor spacing for the size of the cavity pressure structure, more like a plate-fin heat exchanger of honeycomb cellular one by one, thus has the plate-fin heat exchanger of the advantages of compact structure, high heat transfer efficiency. Spiral plate heat exchanger has enough thickness of cylindrical shell, under internal pressure ability is very strong, are all spiral plate together, so in the pit support with the adjacent plate does not need to welding, thus overcome the plate-fin heat exchanger fin between need soldering defects, greatly reduce the processing cost. Also in terms of equipment and large than the plate-fin heat exchanger and plate heat exchanger.
