The evaporator provided by the invention has the main advantages that the blades of the shutters are strong in torsional rigidity, easy to laminate, and not frozen, an automatic water-washed frost program of the evaporator can orderly operate, the defrosting water flow is large, the defrosting time is shortened, and the operating efficiency and refrigerating capacity of the evaporator are improved.
Description
Technical field
The present invention relates to a kind of Vaporizor for refrigerator, particularly a kind of evaporimeter that lever interlock shutter is arranged.
Background technology
In existing lever interlock shutter evaporimeter, the rotating shaft of blade of louver window and the vane end faces of rotating shaft place often have because defrosting residual water low temperature freezes and are frozen on the shaft support plate, cause evaporimeter automatic water defrosting program normally not move.
In existing lever interlock shutter evaporimeter, the blade of louver window torsional rigidity is little, closes the torsional moment of shutter and can not effectively transmit along the length of blade direction, and shutter is closed not tight, and ventilative phenomenon is serious.Icing for preventing that the defrosting water droplet from leaking with the wind, have to reduce the defrosting water yield, cause evaporimeter defrosting overlong time, reduced operational efficiency and the refrigerating capacity of evaporimeter.
Summary of the invention
The objective of the invention is: in order to overcome above deficiency, provide a kind of blade of louver window not to be the technical scheme of the sharp freezing of defrosting residual water, the lever interlock shutter evaporimeter that can closely close, solved in the large-scale food low-temperature freezing plant the automatically difficult problem of water defrosting poor reliability alternately of many group evaporimeters.
Purpose of the present invention is achieved through the following technical solutions: a kind of lever interlock shutter evaporimeter, comprise the evaporimeter that is formed by the fin on evaporation tube, the evaporation tube, the feed pipe that links to each other with evaporation tube and muffler, the evaporimeter below is provided with water leg, discharge outlet and leg, the evaporimeter top is provided with defrosting water pipe and top cover plate, the evaporimeter both sides are provided with deep bead, be installed in shutter on the deep bead and gangbar, pull bar and the lever of sliding shutters on-off action, there is fixedly water fender the shutter top.The blade of shutter is to be connected by the rectangular weldering of the rectangular and L shaped section metallic thin plate of Z-shaped section metallic thin plate, and form the thin wall hollow square tube and extend two wing blades, the two ends of blade have rotating shaft and blade to be connected, the polytetrafluoroethylene (PTFE) end plate is arranged between blade and the deep bead, the shaft support of blade is in the support holes of polytetrafluoroethylene (PTFE) end plate, and polytetrafluoroethylene (PTFE) end plate and deep bead are connected.Polytetrafluoroethylmaterial material is not hydrophilic, polytetrafluoroethylene (PTFE) end plate at low temperatures surface has water freezing also fail to stick, evaporimeter is when cold operation, and the defrosting residual water is frozen and do not caused freezing of rotating shaft, blade and polytetrafluoroethylene (PTFE) end plate, and evaporimeter automatic water defrosting program can orderly function.The thin wall hollow square tube section structure of blade makes blade that large torsional rigidity be arranged, closing the torsional moment of shutter can transmit effectively along the length of blade direction; thin-walled two fins have preferably elasticity; fit easily in wing edge; shutter can closely be closed under the gangbar pulling; can strengthen the defrosting water yield when evaporimeter carries out the water defrosting, shortens the defrosting time, has improved operational efficiency and the refrigerating capacity of evaporimeter.
Further improvement of the present invention is: the blade of shutter is by rectangular weldering connects through the rectangular and L shaped section metallic thin plate of Z-shaped section metallic thin plate of four road bendings, and formation thin wall hollow square tube is extended two wing blades.When shutter is closed, form two pass in wing edge lap-joint and keep out the wind to close and remain silent, it is little to close rear ventilative amount.Because the mutual faying surface in wing edge is little, so be splashed to defrosting water on the blade without the problem of Adsorption And Retention in lap gap, even lap-joint has local freezing, pull open easily because the face that freezes is little, so do not affect the normal unlatching of shutter.
Further improvement of the present invention is: the polytetrafluoroethylene (PTFE) end plate is provided with support holes, and the first sealing ring is arranged in the support holes, and the defrosting residual water in sealing ring prevention polytetrafluoroethylene (PTFE) end plate and the slit, deep bead composition surface enters support holes and freezes.Polytetrafluoroethylene (PTFE) end socket sealing counterbore is arranged, without being detained the icing problem of defrosting water in the screw counter bore that polytetrafluoroethylene (PTFE) end plate and deep bead are connected.
Further improvement of the present invention is: the polytetrafluoroethylene (PTFE) end plate is the S-shaped module of profile, can save the consumption of polytetrafluoroethylmaterial material.
Further improvement of the present invention is: the blade of shutter is made by the hot extrusion aluminium alloy extrusions of integral type, and advantage is to be fit to batch production lever interlock shutter evaporimeter and to reduce manufacturing cost.
Advantage of the present invention is: the blade of louver window torsional rigidity is large, easily fit, evaporimeter is when cold operation, the defrosting residual water is frozen and is not caused blade to freeze, the orderly function of evaporimeter automatic water defrosting program energy, and the defrosting water yield is large, shortens the defrosting time, improves operational efficiency and the refrigerating capacity of evaporimeter.
