Abstract

The utility model relates to an aluminum calandria used for improving the heat exchange efficiency. The aluminum calandria comprises main fins, subsidiary fins and a round pipe, wherein a pair of main fins is radially and symmetrically arranged at the outer side of the round pipe and respectively provided with at least one set of subsidiary fins which are symmetrically arranged with each main fin as a shaft, salient inner ribs are arranged at the inner side of the round pipe, the subsidiary fins are inclined toward the same direction, the inner ribs are symmetrically arranged with the main fins as the shafts, and the pointing direction of a salient tip of each inner rib is the same as the inclined direction of each subsidiary fin. In the aluminum calandria, with the adoption of multi-fin design, the cold exchange area is increased to the maximum extent, and the cost is saved; and with the adoption of the shape and the tooth direction of the inner ribs, refrigeration oil of a tooth space in the pipe can rapidly flow down, thereby is avoiding that the refrigeration oil accumulates in the tooth space, and the cold exchange effect is improved.

Description

Aluminum wrapped calandria

Technical field

The utility model relates to the heat dissipation element of heat-exchange apparatus in the refrigeration system, is specifically related to a kind of aluminum wrapped calandria that improves heat exchange effect.Belong to International Classification of Patents F28F3/00 " parts of interchangeable heat exchange or heat-transfer equipment " technical field.

Background technology

Heat-exchange apparatus used in the prior art, the method that behind great majority employing pipe, light pipe and the fin poling pipe is swollen and combines with fin.When adopting pipe, light pipe, because the heat exchange coefficient of liquid differs greatly with the coefficient of heat transfer of managing outer gas in the pipe, 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.Ratio inside and outside the method that swells behind the fin poling, heat exchange area is quite desirable, but because complex manufacturing technology, equipment requires accurate, and production cost is very high.

Chinese patent CN2791581Y discloses a kind of fin aluminum wrapped calandria, two fins and internal-rib on the basis of former light pipe, have been increased, increased certain heat exchange area, improved the utilization rate of heat exchange material, but the profile fin is less, it is long-pending little to cause changing huyashi-chuuka (cold chinese-style noodles), can not give full play to the refrigeration of cold-producing medium.The internal-rib shape causes refrigeration oil to stockpile in the roller seating space, make refrigerant can't with inwall fully contact change cold.

The utility model content

The technical problems to be solved in the utility model is to overcome the dissatisfactory defective of prior art refrigeration, provides a kind of rational in infrastructure, heat exchanger effectiveness height, the aluminum wrapped calandria of saving cost.

In order to solve the problems of the technologies described above, the utility model provides following technical scheme:

A kind of aluminum wrapped calandria comprises main fin, attached fin and pipe, and the pipe outer radial is symmetrically arranged with a pair of main fin; Being provided with at least one group on the main fin is axisymmetric attached fin with main fin.

The pipe inboard row is shown the internal-rib of projection.

Attached fin tilts to same direction, and internal-rib is an axial symmetry with main fin, and the direction that the protruding top of internal-rib is pointed to is identical with the direction that attached fin tilts.

The projection of internal-rib is a dentation, is preferably sharp tooth.

Preferred attached fin is established two groups.

The utility model has adopted the design of many fins, on the two main fins outside pipe two groups of attached fins is set respectively, has increased that to change huyashi-chuuka (cold chinese-style noodles) long-pending.Under the constant situation of refrigeration, former 1 square metre is changed the long-pending 3 mitron roads that need of huyashi-chuuka (cold chinese-style noodles), adopt the utility model product after, 1 square metre is changed the long-pending 2 mitron roads that need of huyashi-chuuka (cold chinese-style noodles), under the constant situation of refrigeration, has shortened the length of refrigeration pipe, reduce the injection rate of cold-producing medium, saved cost.

Attached fin tilts to same direction, after the aluminum wrapped calandria defrost, can slide along attached fin inclined-plane, guarantees aluminum wrapped calandria Stability Analysis of Structures and refrigeration.

Pipe is provided with internal-rib, can increase the pipe heat exchange area and improve heat exchanger effectiveness.Each internal-rib is a sharp tooth, and internal tooth is symmetry and sensing pipe bottom axially, can allow the refrigeration oil of the interior roller seating space of pipe flow down rapidly, has avoided piling up refrigeration oil in the roller seating space, thereby cold-producing medium more can fully be contacted with inwall, and cold effect is changed in raising.

The specific embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.

Embodiment 1

As shown in Figure 1, arrange the fin tube structure schematic diagram for the aluminium of prior art.Comprise pipe, fin, internal-rib.Pipe outer side center line is provided with a pair of fin, and the pipe inboard is evenly distributed with the internal-rib of projection.

Shown in Fig. 2,4, the utility model aluminum wrapped calandria comprises main fin 1, attached fin 2, pipe 3 and internal-rib 4.Being symmetrical arranged a pair of main fin 1 in pipe 3 outer radial, is that axial symmetry is provided with two groups of attached fins 2 with main fin 1 respectively on described main fin 1.Attached fin 2 tilts to same direction, and establishing attached fin 2 inclinations one side is the lower end.

Shown in Fig. 3,5, pipe 3 inboard row are shown the internal-rib 4 of projection, and internal-rib 4 is a sharp tooth, and internal tooth is an axial symmetry with main fin 1, and the most advanced and sophisticated oblique pointing direction down of tooth top is identical with the direction that attached fin 2 tilts, and points to pipe 3 bottoms.

The main fin 1, attached fin 2, pipe 3, the internal-rib 4 that constitute aluminum wrapped calandria all adopt mold once to make and form.
