Technical field
The present invention relates to the technical field of large cold storage, particularly a kind of tandem 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.
Summary of the invention
The technical problem to be solved in the present invention is: in order to overcome above-mentioned deficiency, the invention provides a kind of tandem aluminum alloy fin cooling grid.
The technical solution adopted for the present invention to solve the technical problems is: a kind of tandem aluminum alloy fin cooling grid, comprise bridge piece and a plurality of finned tube of arranging side by side, described finned tube comprises a light pipe and three longitudinal fins that are arranged on the light pipe outer, contacting by bridge piece between each finned tube is a path, and described path has input and output.
For conserve space and convenient fixing, described fin is in the vertical setting in surface, light pipe outer, comprise two passive first fins and second fin, angle between first fin and second fin is 60 ° ± 30 °, also comprise 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 base plate is fixedlyed connected with the trapezoidal fixed block on each finned tube.
For fixing of evaporimeter integral body, also have two stationary pipes that are used for fixing bend pipe and finned tube, described stationary pipes has installing hole.
In order to guarantee the thermal insulation effect, also comprise a plurality of thermal insulative boards, all have thermal insulative board between the described bridge piece, all have thermal insulative board between input and output and the bridge piece, described thermal insulative board is fixedlyed connected with stationary pipes.
The invention has the beneficial effects as follows that tandem aluminum alloy fin cooling grid of the present invention is provided with three axial fins in the light pipe outer, has determined the angle between fin, this structure is conserve space effectively; Increased trapezoidal fixed block and base plate, structure is fixed, easy for installation; Adopt series connection method that finned tube is linked together, and a plurality of thermal insulative boards are set, preceding road fluid and road, back fluid are separated, and the temperature at bridge piece place separated by thermal insulative board, can effectively play the effect of thermal insulation, it is more stable to dispel the heat; Replace steel pipe with aluminium-alloy pipe, radiating effect is better.
