Technical field
The utility model relates to a kind of deflector means in evaporimeter, particularly relates to a kind of dry evaporator and supports deflector means entirely.
Background technology
Refrigeration air-conditioner is widely used in daily life.The shell-and-tube dry evaporator is the critical piece in the refrigeration system, it is made up of cylinder, steam-generating bank, deflection plate, two ends tube sheet, branch journey bobbin carriage, bearing and corresponding the adapter, and wherein the supporting form of the interior refrigerating medium flow velocity of cylinder and deflection plate will directly have influence on the performance of dry evaporator and the vibration of steam-generating bank is broken.
In the dry evaporator process of refrigerastion, usually the deflection plate form that adopts remains the defective aspect following at present: 1) because the raising of the refrigerating medium flow velocity in the dry evaporator cylinder, steam-generating bank is under the impact of fluid, produce serious flow velocity vibration and frequency vibration, cause the vibration of steam-generating bank to be broken; 2) existing deflection plate is half supporting structure form to steam-generating bank, these deflector means all exist the bearing stride on the steam-generating bank length direction bigger, be easy to generate serious vibration, refrigerating medium can only be realized lower flow velocity, cause the heat transfer property of dry evaporator to descend, cause the processing cost height, uneconomical, not energy-conservation.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, provide that a kind of shape and structure is succinct, good airproof performance, effectively dry evaporator to support deflector means entirely be the purpose of this utility model place.Technical solutions of the utility model are by the full supporting deflector means in the dry evaporator cylinder refrigerating medium flow velocity to be improved fully, the all evapn tube bank effectively realizes full supporting form, steam-generating bank effective bearing stride in the longitudinal direction reduces half, prevent the vibration of steam-generating bank, effectively improved the evaporimeter heat transfer property.The technical solution of the utility model is come specific implementation by following technical measures, a kind of dry evaporator supports deflector means entirely, it is characterized in that it is made up of full supporting deflection plate and the tube sheet and the steam-generating bank that are associated, described full supporting deflection plate is a plane breach plectane in the evaporimeter cylinder, its excircle sideband featheredge, with the applying in increase and the evaporimeter cylinder, the thickness of plane breach plectane is 3mm-12mm; the thickness of featheredge is 0.3mm-0.6mm; the width of featheredge is 5mm-10mm; the cut height of plane breach plectane is the 13-20% of barrel bore; the pore of distribution and tube sheet equal number on the plane breach plectane, and the aperture of pore is adjusted according to the various outer diameter of steam-generating bank; Full supporting deflector means form be all evapn tube bank is penetrated some breach up and down or about in the pore on the full supporting deflection plate of dislocation, full supporting baffling plate number is determined by the length of dry evaporator, be the 3-25 piece, and according to the spacing between the fixing full supporting deflection plate of refrigerating medium flow size, be 60mm-500mm, supporting pore on the deflection plate and the external diameter of steam-generating bank entirely is matched in clearance.
Described full supporting deflection plate arranges reinforcement and the corresponding strong point, to gain in strength for the full supporting deflection plate of large diameter plane breach plectane between pore.
The utility model dry evaporator supports deflector means entirely and using method is: refrigerating medium is entered in the cylinder by the inlet tube on the dry evaporator, by all evapn tube bank penetrate some breach up and down or about carry out baffling on the full supporting deflection plate of dislocation, make refrigerating medium between full supporting deflection plate, reach flow at high speed in the breach, increase turbulent flow, fully finish the process of heat exchange.
The beneficial effects of the utility model are, the deflector means that this dry evaporator supports has entirely adopted the full supporting deflection plate of outer round belt featheredge, plane breach plectane, make all evapn tube bank effectively realize full supporting form, when refrigerating medium is realized high flow rate, prevent the vibration of steam-generating bank, effectively improved the evaporimeter heat transfer property.Existing deflector means has improved the efficiency of 15-20%, is that a kind of shape and structure is succinct, good airproof performance, and fabrication and installation are convenient, the energy saver that processing cost is low.
