Abstract

The utility model relates to a straight-through aluminum alloy arrayed finned tube evaporator, which comprises an input tube, an output tube and a plurality of finned tubes which are arranged side by side, wherein one end of each finned tube is communicated with the tube body of the input tube, and the other end of each finned tube is communicated with the tube body of the output tube; and each finned tube comprises a light tube and three axial fins arranged on the outer edge of the light tube. In the straight-through aluminum alloy arrayed finned tube evaporator, the three axial fins are arranged on the outer edge of the light tube, so that angles among the fins are determined; and a base plate connected with the finned tubes is arranged in parallel to the plane in which the input tube and the output tube are placed. By the structure, the space can be saved effectively; a trapezoid fixing plate and the base plate are arranged, so that the structure is fixed, and the straight-through aluminum alloy arrayed finned tube evaporator is convenient to mount; the finned tubes are connected together in parallel; fluid can be continuously radiated after being radiated by the front finned tube, so that the radiating effect is enhanced, the refrigerating efficiency of a refrigerator is improved, and the refrigeration can be performed more quickly; furthermore, the aluminum alloy replaces a steel tube, so that the radiating effect is good.

Description

Through type aluminum alloy fin cooling grid

Technical field

The utility model relates to the technical field of large cold storage, particularly a kind of through type aluminum alloy fin cooling grid.

Background technology

Existing finned tube adopts the method that pipe is risen and combines with fin greatly behind pipe, light pipe and the fin poling usually.When adopting pipe, light pipe, because the heat exchange coefficient of pipe inner fluid and the coefficient of heat transfer of pipe place fluid differ greatly, the heat-exchange capacity in the pipe outside is little, and the operating efficiency of light pipe is very low, causes a large amount of wastes of material.Simultaneously, what existing evaporimeter usually adopted is this finned tube, and surface area is less, and radiating effect is poor, and institute take up space bigger, the wasting space resource.

The utility model content

The technical problem that the utility model will solve is: in order to overcome above-mentioned deficiency, the utility model provides a kind of through type aluminum alloy fin cooling grid.

The utility model solves the technical scheme that its technical problem adopted: a kind of through type aluminum alloy fin cooling grid; Comprise input pipe, efferent duct and a plurality of finned tube of arranging side by side; Described finned tube one end all is connected with the body of input pipe; The other end all is connected with the body of efferent duct, and described finned tube comprises a light pipe and three longitudinal fins that are arranged on the light pipe outer.

For conserve space is fixed with convenient; The vertical setting of described fin on surface, light pipe outer; Comprise two passive first fins and second fin, the angle between first fin and second fin is 60 ° ± 30 °, also comprises the 3rd fin; The 3rd fin equates that with the angle of first fin and second fin described angle is 150 ° ± 15 °.

For each fin is fixed; Has a trapezoidal fixed block of fitting between described first fin and second fin with first fin and second fin; Trapezoidal fixed block bottom has the base plate that makes each finned tube location, and described base plate is fixedly connected with trapezoidal fixed block on each finned tube.

For better conserve space, described base plate is with respect to the plane parallel setting at input pipe and efferent duct place.

The beneficial effect of the utility model is; The utility model through type aluminum alloy fin cooling grid; Three axial fins are set in the light pipe outer; Confirmed the angle between fin, and connected the plane parallel setting of the base plate of finned tube with respect to input pipe and efferent duct place, this structure is conserve space effectively; Increased trapezoidal fixed block and base plate, structure is fixed, easy for installation; Employing and linked method link together finned tube, and fluid can be proceeded heat radiation after dispelling the heat through preceding road finned tube, has strengthened radiating effect, improves the refrigerating efficiency of freezer, makes refrigeration faster; Replace steel pipe with aluminium-alloy pipe, radiating effect is better.
