Abstract
The utility model discloses a combined fin with fan-shaped and bridge-shaped crevasses, which is used in a heat exchanger. As an improvement of a common plate fin, the fin comprises a substrate, on which a plurality of pipe holes are arranged. The combined fin with the fan-shaped and bridge-shaped crevasses is characterized in that: on the substrate, a plurality of fan-shaped crevasses are coined around the pipe hole periphery and a bridge-shaped crevasse is coined between every two horizontal pipe holes; and the combined fin can effectively break a 'boundary layer' caused by the flow of fluid along the surface when in use, thus enhancing the fluid disturbance, being capable of effectively preventing solid dust deposit in the fluid and being widely applied in oil heat exchangers and gas heat exchangers having high performance requirements in petrochemical engineering, vessel, metallurgy, naval vessel, electric power and other industries.
Description
(1) technical field:
The utility model relates to machinery manufacturing technology field, is a kind of fan-shaped and bridge shape crevasse combined type fin that is used for heat exchanger.
(2) background technology:
Use fin and be and improve simple and direct and one of the effective means of heat exchanger efficiency.Common fin is the some pores of punching out on a flat plate substrate, is referred to as plate fin.Experiment shows that in use when flowing along planomural is surperficial because of fluid, there is one deck " boundary-layer " in plate fin near wall, and the thermal resistance of being somebody's turn to do " boundary-layer " is very big, and thermograde is just very big, influences heat transfer efficiency.
(3) summary of the invention:
It is big that the purpose of this utility model will solve existing plate fin thermal resistance exactly, and thermograde is big, influences the problem of heat transfer efficiency, and a kind of fan-shaped and bridge shape crevasse combined type fin is provided.
Concrete scheme of the present utility model is: improve at plate fin, it has substrate, has some pores on the substrate, it is characterized in that: on substrate, around the punching out of pore periphery some fan-shaped cuts are arranged, and in the horizontal in twos between the pore punching out bridge shape cut is arranged.
In the utility model, on substrate, four uniform fan-shaped cuts are arranged around the punching out of pore periphery.
In the utility model, the bridge shape cut of substrate punching out is lateral arrangement.
The utility model is simple in structure, its fan-shaped and bridge shape cut is in on-chip applied in any combination, can effectively destroy " boundary-layer " that produce when fin in use flows along the surface because of fluid, strengthen the disturbance of fluid, can prevent simultaneously solid dust deposition in the fluid effectively, be widely used in oil heat exchanger, the gas heat exchanger of industry high performance requirements such as petrochemical industry, boats and ships, metallurgy, naval vessels, electric power.
(4) description of drawings:
Fig. 1 is a front view of the present utility model;
Fig. 2 is a left view of the present utility model;
Fig. 3 is the A-A view of Fig. 1;
Fig. 4 is the B-B view of Fig. 1;
Fig. 5 is the zoomed-in view at Fig. 4 I place.
Among the figure: 1-copper sheet, 2-pore, 3-bridge shape cut, the fan-shaped cut of 4-.
(5) specific embodiment:
Referring to Fig. 1, Fig. 2, the utility model adopts copper sheet 1 to make substrate (length and width need be determined by the arrangement space of heat exchanger), the some pores 2 of punching out (determining the position and the quantity of pore according to the layout of heat exchanger tube) on copper sheet 1, particularly on copper sheet 1, also four fan-shaped cuts 4 (referring to Fig. 4,5) are arranged around pore 2 peripheral punching out, and in the horizontal in twos between the pore punching out bridge shape cut 3 (referring to Fig. 3) of a lateral arrangement is arranged.
Claims (3)
1. fan-shaped and bridge shape crevasse combined type fin has substrate, has some pores on the substrate, it is characterized in that: on substrate, some fan-shaped cuts are arranged around the punching out of pore periphery, and in the horizontal in twos between the pore punching out bridge shape cut is arranged.
2. fan-shaped and bridge shape crevasse combined type fin according to claim 1 is characterized in that: on substrate, around the punching out of pore periphery four uniform fan-shaped cuts are arranged.
3. fan-shaped and bridge shape crevasse combined type fin according to claim 1 is characterized in that: the bridge shape cut of substrate punching out is lateral arrangement.
