In the tandem aluminum alloy fin calandria evaporator, the three axial fins are arranged at the outer edge of the light pipe, so that the angle between the fins is fixed, and the space can be effectively saved by adopting the structure; trapezoidal fixing blocks and a bottom plate are additionally arranged to ensure that the structure is firm, and the installation is convenient; the fin pipes are connected in series, and a plurality of thermal baffles are arranged, so that the front-path fluid is separated from the rear-path fluid; besides, the heat at the connecting bent pipes is isolated by the thermal baffles, so that the thermal isolation effect can be effectively achieved, and the heat dissipation is more stable; and the aluminum alloy is used for replacing steel pipes, so that the heat dissipation effect is even better.

Description

Tandem aluminum alloy fin cooling grid

Technical field

The utility model 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.

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 tandem aluminum alloy fin cooling grid.

The utility model solves the technical scheme that its technical problem adopted: 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 through bridge piece between each finned tube is a path, and described path has input and output.

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 base plate is fixedly connected with trapezoidal fixed block on each finned tube.

For whole the fixing of evaporimeter, 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 fixedly connected with stationary pipes.

The beneficial effect of the utility model is, the utility model tandem aluminum alloy fin cooling grid is provided with three axial fins in the light pipe outer, has confirmed the angle between fin, and 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.
