Description of drawings
Fig. 1 is a kind of finned coil heat exchanger structural representation of the present utility model;
Illustrate:
Housing 1, inner core 2, finned coil 3, flange and blind flange 4,, pipe 41, joint 42, low specific heat fluid inlet A, low specific heat fluid issuing B, high specific heat fluid inlet C, high specific heat fluid issuing D, sewage draining exit E.
The specific embodiment
A kind of finned coil heat exchanger of the present utility model as shown in Figure 1, comprises that housing 1, inner core 2, finned coil 3, flange and blind flange more than 4 parts form.Housing 1 one ends sealing, affixed with the cylindrical sealing of inner core 2 one ends, housing 1 other end is opening, with flange and blind flange 4 sealings.Inner core 2 is positioned on the axis of housing 1.Inner core 2 two ends are opening, and an end is low specific heat fluid inlet A, and the other end is suspended from the housing 1, with flange and blind flange 4 inwalls on the housing 1 one gap are arranged.Housing 1 upper side wall is provided with low specific heat fluid issuing B, and lower wall is provided with sewage draining exit E.
Inner core 2 peripheries circle at least rotating disc is established two-layer finned coil 3, between the two-layer finned coil 3, between coil pipe and the inner core 2, every coil pipe all is provided with the gap each other.
Flange and blind flange 4 are provided with two through hole, and each sealing is connected with a pipe 41 in the two through hole, and there is joint 42 the inner of pipe 41, and two holes on the joint 42 are affixed with the termination sealing of two-layer finned coil 3 respectively, and communicate with the coil pipe inner chamber, form the loop.The outer end of two pipes 41 is opening, and one is high specific heat fluid inlet C, and another is high specific heat fluid issuing D.
Finned coil 3 is comprised of parent tube, fin wing, inside spin muscle.The inwall of parent tube is provided with the inside spin muscle of projection; Vertically be provided with the fin wing on the cylindrical wall of parent tube.The size of inside spin muscle projection is about 0.5mm.The size of fin wing, height is between 1.6～13mm.
Low specific heat fluid inlet A, low specific heat fluid issuing B are communicated with low heattransfer rate body source sealing respectively, form the loop.High specific heat fluid inlet C, high specific heat fluid issuing D are communicated with the sealing of high specific heat fluid source respectively, form the loop.
At first finned tube is carried out the Technologies for Heating Processing such as normalizing, with special-purpose machinery equipment that finned coil 3 dish curls are whole again, finned coil 3 both ends opens are in a side, and make finned coil 3 internal diameters and inner core 2 cylindricals of helical form integral body suitable.After adopting high silver solder to weld after the two ends of every helical form finned coil 3 are connected with joint 42 respectively, be positioned in the housing 1 from the opening part of housing 1, be placed in inner core 2 cylindricals.Affixed with housing 1 with flange and blind flange 4 again, become finished product.
The utility model has the advantage of:
1. coil pipe 3 itself is to process according to spiral line type, thus after passing through the inside of inner core 2, fluid can flow along the spatially spiral between coil pipe 3 and the housing 1, thus reduced flow resistance.Inner core 2 except the fixed support effect is arranged, also plays the equally distributed effect of air-flow that makes on the axis of whole heat exchanger.
The heat exchange device by whole finned coil 3 around forming, one-body molded, do not have the tube sheet of tubular heat exchanger, so do not exist expansion tube process, solve tubular heat exchanger and caused the phenomenon of " collaborating " because expand tube is bad, more reliable than the tubular heat exchanger of routine, safer.The existing finned tube technique in market is solder technology, is the whole finned tube that rolls one and the utility model adopts, the solderless contact, and contactless thermal resistance, heat transfer efficiency is higher, resistance to thermal shock and mechanical shock, hot expansibility is good, and rigidity is strong.
3. because wing is higher than coefficient, improved significantly heat exchange efficiency, less than conventional light pipe heat exchanger volume, can reach the same volume of plate type heat exchanger, but higher than plate type heat exchanger reliability, inside spin muscle line is arranged in the pipe, can form disturbance by convection cell, so be not easy fouling, solved simultaneously the narrow easily dirty stifled problem of plate type heat exchanger circulation passage.
4. the version of flange and blind flange, conveniently maintenance and cleaning.
5. product itself has been gathered all advantages of tubular heat exchanger and plate type heat exchanger, can bear larger pressure (through the compression failure experiment of 20Mpa, finished product is intact), the pressure loss is little, the potential safety hazard of more solved the long-standing easy foulings of all heat exchangers, easily revealing, the scope of application is wider, can be widely used in gas-gas heat exchange, gas-liquid heat exchange etc., can produce condenser, heat exchanger, evaporimeter, heater etc.
Performance of the present utility model and existing product are relatively such as table 1:
Table 1
Above-described only is preferred embodiment of the present utility model; should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and transformation; or the utility model product is positioned in any correlation machine equipment, these all belong to scope of patent protection of the present utility model.
