Abstract
The utility model provides a fin structure for indirect heating equipment has effectively avoided air current movable property life and death point, has further improved heat exchange efficiency, and it includes the fin body, be provided with a plurality of tubs of mounting holes on the fin body, the pipe mounting hole for the slope of fin body is arranged, the fin body along airflow direction's both sides along arranging the first fin that turns over on having, the fin is along the airflow direction slant the middle zone of fin body closes up. Its characterized in that: this internally is provided with a plurality of second fins the fin.
Description
Technical field
The utility model relates to the technical field of heat transmission equipment parts, is specifically related to a kind of heat transmission equipment fin structure.
Background technology
Finned heat exchanger is heat-exchanging part main in heat-exchange system, the energy consumption of the good and bad heat exchanging system of its performance plays a part very important, the shape of fin, size directly will affect the ability of heat exchange, common fin structure is plain film or corrugated plate, when carrying out heat exchange along airflow direction, the border area temperature field of fin is not good, non-optimal heat exchange area, but the air velocity of the border area of fin, air unit section flow is all higher than the zone line of fin, zone line due to fin is optimum heat exchange area, applicant has invented a kind of fin structure (publication number is CN202361876U) of heat transmission equipment, in this utility model, just fin body is arranged with along two edges of airflow direction the fin turned over, fin closes up along the zone line of the oblique fin body of airflow direction, the configuration achieves the air mass flow of both sides is directed into heat transfer effect preferably zone line carry out heat exchange, but import in the process of zone line in air mass flow, the flow direction of air stream is comparatively stable, easily there is air flowing dead point, have impact on heat exchange efficiency.
Summary of the invention
For the above-mentioned technical problem that prior art exists, the utility model provides a kind of heat transmission equipment fin structure, effectively prevent air flowing and produces dead point, further increase heat exchange efficiency.
To achieve these goals, the utility model realizes by the following technical solutions: a kind of heat transmission equipment fin structure, it comprises fin body, described fin body is provided with multiple pipe installing hole, described pipe installing hole is in tilted layout relative to described fin body, two edges along airflow direction of described fin body are arranged with the first fin turned over, described first fin closes up along the zone line of the oblique described fin body of airflow direction, it is characterized in that: be provided with multiple second fin in described fin body.
It is further characterized in that: the water conservancy diversion direction of described second fin and the water conservancy diversion direction of described first fin staggered; Described first fin and described second fin are respectively towards the same side flanging of described fin body; Described second fin is square fin, and described square fin is that it is shaping that the 4th limit connects described fin body at described fin body three limit opening; Described second fin turning over angle is 70 ° ~ 90 °;
Described first fin is triangle fin; Described first fin is symmetrically arranged in two edges along airflow direction of fin body; Described first fin turning over angle is 70 ° ~ 90 °.
In said structure of the present utility model, owing to being provided with multiple second fin in fin body, when air mass flow is directed into heat transfer effect by the first fin preferably zone line carries out heat exchange, through the secondary water conservancy diversion of the second fin, expand the distribution area of air mass flow, effectively prevent air flowing and produce dead point, further increase heat exchange efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model heat transmission equipment fin structure front view;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the left view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described:
See Fig. 1, Fig. 2, Fig. 3,
A kind of heat transmission equipment fin structure, it comprises fin body 1, fin body 1 is provided with multiple pipe installing hole 2, pipe installing hole 2 is in tilted layout relative to fin body 1, two edges along airflow direction of fin body 1 are arranged with the first fin 3 turned over, first fin 3 is triangle fin, first fin 3 interlaced arrangement is in two edges along airflow direction of fin body 1, first fin 3 turning over angle is 70 ° ~ 90 °, first fin 3 closes up along the zone line of the oblique fin body 1 of airflow direction, multiple second fin 4 is provided with in fin body 1, second fin 4 is square fin, square fin 4 is at fin body 1 three limit opening, 4th limit connects described fin body 1, second fin 4 turning over angle is 70 ° ~ 90 °, when air mass flow is directed into heat transfer effect by the first fin preferably zone line carries out heat exchange, through the secondary water conservancy diversion of the second fin, expand the distribution area of air mass flow, effectively prevent air flowing and produce dead point, further increase heat exchange efficiency.
First fin 3 interlaced arrangement, in two edges along airflow direction of fin body 1, expands the scope that air mass flow flows in fin body, improves the distribution area of air mass flow in fin body, improves heat exchange efficiency.
The water conservancy diversion direction of the second fin 4 and the water conservancy diversion direction of the first fin 3 staggered, second fin 4 is arranged in the position, dead angle of air-flow after the corresponding heat exchanger tube in pipe installing hole 2 end, effectively prevent air mass flow and occur dead angle in fin body, ensure that the distribution area of air mass flow in fin body strengthens, further improve heat exchange efficiency.
The flange direction of the second fin 4 is identical with the flange direction of the first fin 3, first fin 4 and the second fin 4 are respectively towards the same side flanging of fin body 1, first fin and the second fin are processed by plug, the flange direction of the second fin is identical with the flange direction of the first fin, during fin subsequent installation, air mass flow is concentrated between two fins, is covered with fin inside, improves heat exchange efficiency.
