Abstract

The utility model discloses a novel heat exchanger fin, which adopts a structure design which is different from the prior art. A fin main body is arranged, the middle of the fin main body is thick, and the position from the middle to the edge is gradually thin. The utility model has the advantages that a heat-transferring path is widened, and that heat-transferring efficiency is improved, so that the integral heat-transferring efficiency of the heat exchanger is improved; the number of the fins and the length of a pipeline can be reduced, which saves labor and materials and reduces cost.

Description

The novel heat exchanger fin

The utility model relates to the interchangeable heat exchange in the general hot swapping or the parts of heat-transfer equipment, is a kind of assembly of pipe fitting, specifically, is a kind of pipe fitting assembly of widening heat transfer path.

The signal wide range of heat exchanger, the radiating fin on the heat exchanger then are its requisite parts.Existing heat-exchanger fin, no matter be and carry the version that the Cooling and Heat Source pipeline is combined as a whole or the fin part of assembly type heat exchanger, there is not too big variation on its structure for these years, body cross-section all adopts rectangular configuration, such heat-exchanger fin, not only unreasonable on the structure, the thermal efficiency is not high, and consume material, heavy, volume is big.

The purpose of this utility model provides a kind of simple in structure, new reasonable, can effectively improve heat transfer efficiency, help reducing cost, reduce the novel heat exchanger fin of the volume and weight of heat exchanger.

Technical solution of the present utility model is: a kind of novel heat exchanger fin, and it has adopted and has been different from prior art constructions design: a fin main body is arranged, and fin main body center is thick, and middle part to edge attenuate gradually.

Fin main body described in the utility model is connected as a single entity with the pipeline of carrying Cooling and Heat Source.Certainly, also can adopt the version that is split up into independent part.

The cross section of the fin main body described in the utility model is a triangle or trapezoidal.Certainly, also can adopt other suitable shape and structures.

Fin main body described in the utility model is the porose independent fin in middle part, or is connected into an assembly by a plurality of porose fins.Certainly, also can adopt other suitable versions.

The utility model has the advantages that: simple in structure, new reasonable, widened heat transfer path, improved heat transfer efficiency, thereby the whole heat transfer efficiency of heat exchanger is improved, can reduce the quantity and the duct length of fin, but saving of labor's material-saving has again reduced cost.

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is the structural representation of a kind of novel heat exchanger fin of the present utility model;

Fig. 2 is the structural representation of another kind of novel heat exchanger fin of the present utility model;

Fig. 1 has described an embodiment of the present utility model.On the pipeline 1 of the conveying Cooling and Heat Source of heat exchanger, the plate-like fin 2 of making one with it is arranged in this example, the profile of plate-like fin 2 is the even circle (or other suitable shapes) around circular pipe, and the basic configuration of the main heat-exchange surface of its cross section is a triangle.

Fig. 2 has described another embodiment of the present utility model.On the pipeline 1 of the conveying Cooling and Heat Source of heat exchanger the plate-like fin 22 of making one with it is arranged in this example, the basic configuration of the main heat-exchange surface of the cross section of plate-like fin 22 is trapezoidal.

The foregoing description is compared with the old fin that uses same weight and material, and not only in light weight, materials are economized, and heat transfer efficiency also is improved.

Certainly, the utility model can also adopt other suitable embodiments, composite unit structure form that has a plurality of porose fins to be coupled to each other to form as employing etc.
