Description
Technical field
The utility model relates to honeycomb cellular type heat exchanger.
Background technology
Existing dividing wall type heat exchanger can be divided into shell-and-tube heat exchanger, plate type heat exchanger, double pipe heat exchanger or the like according to the heat-transfer area difference; Plate type heat exchanger coefficient of heat transfer height wherein, good energy-conserving effect, but it is not withstand voltage, stops up easily, has greatly limited the plate type heat exchanger range of application.Though and shell-and-tube heat exchanger is withstand voltage, its coefficient of heat transfer is low, and takies local big, not energy-conservation.Chinese patent specification ZL200920095299.8 discloses a kind of honeycomb ceramic heat exchanger, comprise by the basic unit moduleization of sealing of one or more main heat exchange elementary cells and two or main heat exchange elementary cell quantity twice and forming, be used for high-temperature flue gas and be heated gas carrying out heat exchange, owing to adopt the relatively poor ceramic material of heat conductivility, volume is bigger, and heat exchange efficiency is not high, and is not withstand voltage, the scope of application is narrow, is easy to generate internal leakage.Chinese patent specification CN101907411A discloses a kind of plate hole cascade type heat exchange device, comprise by some honeycomb orifice plates and shape size sealing heat insulating mattress or the fluid sealant alternate honeycomb hole plate type heat exchanging element that be formed by stacking identical with it, this heat exchanger plate hole uses metal material, submit mistake at the honeycomb plate hole and be arranged with several rows cold fluid and hot fluid through hole, though can improve heat transfer rate, but because of the heat exchange main body adopts honeycomb orifice plate stacked system, inconvenience is installed, seal with sealing heat insulating mattress or fluid sealant between each plate hole, leak source is many, sealing effectiveness is not good, is difficult to bear high pressure.2011100516204 of I oneself application is the improvement to above patent application, its water conservancy diversion frid that connects at heat exchange unit body two ends is provided with boss in the end outwardly, on boss, be provided with some corresponding with the heat exchange unit body but do not pass the honeycomb hole of this end face of boss, the long shunt or the groove that confluxes (being guiding gutter) communicate with all honeycomb holes of equidirectional arrangement, have the groove that is communicated with colleague's honeycomb hole at the honeycomb ceramics end face, this groove only is a UNICOM colleague honeycomb hole forming the fluid passage, confluxes or shunts to realize fluid.Found through experiments it and have following shortcoming: (1) still has stifled phenomenon of gas and bottleneck effect, is difficult to discharge the highest heat exchange efficiency; (2) integral sealing effect is not ideal; (3) the heat exchanger disassembly, cleaning are not too convenient.The import and export of the import and export of its cold fluid and hot fluid have only one group in addition, this structure can cause and form bottleneck effect in guiding gutter, hinder rapid flow of fluid, just slow away from the local flow velocity of fluid inlet and outlet, and can oppress in the volume gas and enter end and cause gas to block up phenomenon.
The utility model content
The purpose of this utility model is the improvement to 2011100516204 patents, provides a kind of heat exchange efficiency higher, and integral sealing effect is better, disassembly, cleaning honeycomb cellular type heat exchanger more easily.
The technical solution of the utility model is: comprise the heat exchange unit body, the upper and lower cold fluid and hot fluid clutch at heat exchange unit body two ends, reverse cold fluid import and export and the hot fluid import and export that is arranged on cold fluid and hot fluid clutch two ends; It is characterized in that, described heat exchange unit body is to be shaped to the alveolate texture that the honeycomb hole that adjoins mutually constitutes by metal integral, described cold fluid and hot fluid clutch and guiding gutter are combined into one, having the partition seal groove on the partition between per two row honeycomb holes on two end faces of heat exchange unit body, outer placing at two end faces is provided with the sealing frame, each partition seal groove formation integral seal that links to each other with the sealing frame, with shunting or collecting tray and up and down clutch combine together; The import of described cold fluid and the outlet of hot fluid alternately are arranged with the 1-100 group.
Be provided with steam vent above the described upward cold fluid and hot fluid clutch.
The cross sectional shape of described honeycomb hole is circle or polygon, and pore wall thickness is 0.3-7mm.
Described metal is copper, aluminium, iron or other alloy.
Advantage of the present utility model: (1) each partition seal groove links to each other with the sealing frame and constitutes integral seal, and sealing effectiveness is better, can prevent to leak in the fluid and leak; (2) import and export of the import and export of cold fluid and hot fluid are many groups, and this structure can reduce bottleneck effect, promotes rapid flow of fluid, reduce the stifled generation of gas; (3) on last clutch, be provided with steam vent,, also can make gas be unlikely to stop up the fluid passage even there is the stifled situation of gas to take place; Above technical scheme more helps the staggered heat exchange of two fluids, heat exchange area is fully utilized, thereby improved the coefficient of heat transfer of heat exchanger greatly; (4) shunting or collecting tray and up and down clutch combine together, greatly made things convenient for heat exchanger sealing and disassembly, cleaning; (5) the honeycomb shape is very withstand voltage, and its voltage withstand class is up to more than the 10Mpa, and the coefficient of heat transfer can reach 10000w/m2 ﹒ H ﹒ C, (6) but metal material is saved in weight reduction.
