Description
Technical field
The utility model relates to a kind of aluminium alloy evaporation tube of freezing plant.
Background technology
Along with the development of cold chain technology and the popularization of application thereof, various forms of freezing plant is weeded out the old and bring forth the new.Wherein, shelf-type cooling grid is used for chilled of frozen processed food in freezing room, particularly applicable for dish dress scars.Existing shelf-type evaporimeter, its evaporation tube often adopts steel pipe or aluminium-alloy pipe etc., cold dish (dish dress scars) or be directly placed on pipeline or be placed on the bellows flat board of flat board and the upper aluminium alloy extruded one-tenth of employing for plane laid.In actual applications, be difficult to accomplish to contact nearly at the bottom of cold dish with comb flat board, thermal contact resistance is comparatively large, reduces the reliability of freezing process.Tradition shelf-type evaporator heat transfer divides heat transfer and air heat-exchange, and heat transfer share is low is the major reason causing this kind of evaporator effectiveness lower.In addition, bellows flat board plate pipe area ratio---wing coefficient value is too high, wing efficiency reduce, namely there is the heat transfer plate face of partial invalidity in bellows flat board, for adopting by the lower freezing plant circulated from upper pressure cold wind, flat board adds windage, being uniformly distributed of unfavorable temperature field.
Summary of the invention
In order to solve deficiency of the prior art, the purpose of this utility model is that heat-transfer effect is good, the aluminium alloy evaporation tube that applicability is wide for freezing plant provides a kind of effectively heat transfer area large.
For achieving the above object, the utility model is by the following technical solutions:
A kind of aluminium alloy evaporation tube of freezing plant, comprise by the shaping body of aluminum alloy materials, the tube wall of described body is made up of roof, diapire and two side, the width of described diapire is less than the width of roof, the lateral surface of described roof is bright and clean plane, cold dish is directly held on the lateral surface of roof, the medial surface of roof is provided with the first fin structure, the lateral surface of described two side is the structure to tubular body arcuation projection, and the lateral surface of described two side is equipped with the second fin structure.
The medial surface of described roof is the structure to tubular body arcuation projection.
The medial surface of described two side is the structure to tubular body arcuation projection.
The lateral surface of described diapire is plane.
The junction of described roof, diapire and two side is equipped with knuckle.
The width of described diapire is 1/2 of roof width.
The utility model adopts above technical scheme, has following characteristics:
1 ﹑ cold dish can directly be held on aluminium alloy evaporation tube roof lateral surface, because aluminium alloy evaporation tube roof lateral surface is bright and clean plane, compared with pipe, cold dish bottom surface becomes face with aluminium alloy evaporation tube end face from linear contact lay and contacts, heat-conducting area increases, thermal contact resistance reduces, the share of this heat conduction amount just making the heat in cold dish be contacted with roof face by cold dish is significantly improved, and effectively improves to freeze product and freeze quality, freezing speed, reduces energy consumption etc.;
2 ﹑ contact well with aluminium alloy evaporation tube roof lateral surface because of cold dish bottom surface, the partial outer face of cold dish amasss the effect of the extension area ﹙ wing sheet ﹚ with aluminium alloy evaporation tube, this effect is equivalent to aluminium alloy evaporation tube tube wall and air cold carrier convection heat transfer' heat-transfer by convection area increase to a certain degree, and heat-transfer effect increases.
3, above-mentioned aluminium alloy evaporation tube, adopt by lower from pressure cold wind circulation freezing plant in, when air cold carrier is horizontal plunder evaporation tube time, its profile wide at the top and narrow at the bottom, two side are to the structure of arcuation projection in pipe, to air circulation, there is guide functions, reduce air circulation resistance, and the convection heat transfer of the outer surface of air and its sidewall and diapire, its coefficient of heat transfer is far below the boiling coefficient of inside pipe wall, the fin of the low clearance of pipe lateral surface, can augmentation of heat transfer, improve the freezing speed of product.
It is the refrigerant air-liquid mixture containing lubricating oil in aluminium alloy evaporation tube tube cavity described in 4 ﹑, the each wall of tube cavity is bright and clean, the fin of four knuckles and longitudinal low clearance, lubrication oil accumulation ﹑ film forming can be prevented, and refrigeration system can be returned with cold-producing medium.Tube cavity non-circular shape, namely bottom wall width is 1/2 and roof medial surface of roof width, two side is arcuation bulge-structure to tubular body, make tube cavity two sides because being heated, refrigerant gas bubbles is produced in its side wall inner surfaces, bubble parameters, rises and constantly washes away the inner surface of sidewall, forms cold-producing medium in side wall inner surfaces to tube hub inside Natural Circulation from top to bottom, the interior dry wall phenomenon of the pipe that avoids evaporating, efficient hardening heat release.
5, the lateral surface of diapire is plane, is convenient to evaporation tube to be mounted to heat exchange evaporation comb.
