Definitions

  • the invention relates, generally, to a fin and, more specifically, to a corrugated fin and a heat exchanger that includes the fin.
  • a heat exchanger When a heat exchanger is used as an evaporator, a lot of condensate may be accumulated on surfaces of the fins due to structure limitation of the conventional corrugated fin, thus not only influencing the heat-transfer performance of the heat exchanger, but also increasing the air resistance of the surface of the heat exchanger and, thereby, the power consumption of the air blower.
  • the conventional fin when the conventional fin is used in an inverted V-shaped or flat-plate-shaped heat exchanger, an inclination angle is formed between the surface of the heat exchanger and a horizontal plane. Because the condensate is accumulated on the surface of the heat exchanger during operation, the condensate may directly drop into an air pipe below the heat exchanger from the surface of the heat exchanger.
  • a corrugated fin that is used for a heat exchanger and has a good water-drainage performance. More specifically, there is a need in the related art for such a fin such that no condensate drops directly from a surface of the heat exchanger during operation and stoppage, good heat-exchange performance is ensured, and air-side-pressure drop is not too large. There is a need in the related art also for a heat exchanger that uses the fin.
  • the invention overcomes the disadvantages in the related art in a corrugated fin that includes connection segments each of which is formed with louvers.
  • Substantially circular arc segments are connected with the connection segments alternatively in a substantially longitudinal direction such that corrugations are formed and the arc segments form respective crests and troughs of the corrugations.
  • 0 ⁇ H 2 ⁇ (H 1 ⁇ 2R+2R sin ⁇ )/cos ⁇ in which “H 2 ” is a length of the corresponding louver, “H 1 ” is a height of the fin, “R” is a radius of the corresponding arc segment, and “ ⁇ ” is an angle of inclination of the corresponding connection segment.
  • the invention overcomes the disadvantages in the related art also in a heat exchanger that includes a first header, a second header spaced apart from the first header, and tubes spaced apart from each other and each of which is connected between the first and second headers in fluid communication therewith. Fins are each disposed between adjacent tubes.

  • Another advantage of the fin and heat exchanger of the invention is that normal air-side-pressure drop is ensured.
  • Another advantage of the fin and heat exchanger of the invention is that formation or accumulation of condensate drops on the louvers and a surface of the fins may be reduced or eliminated so that the condensate may flow onto the tubes along the fins and gather into a water-collecting pan along the tubes rather than drop into the air pipe.
  • Another advantage of the fin and heat exchanger of the invention is that no water leakage may occur in the unit using the heat exchanger.
  • Another advantage of the fin and heat exchanger of the invention is that the air pipe may not be corroded.

  • a corrugated fin 4 includes substantially circular arc segments 41 and connection segments 42 .
  • the arc segments 41 are connected with the connection segments 42 alternatively in a substantially longitudinal direction such that corrugations are formed and the arc segments 41 form respective crests and troughs of the corrugated fin 4 .
  • the connection segment 42 can be referred as a “fin wall” of a corrugation of the corrugated fin 4
  • the arc segment 41 can be referred as a “crest” and “trough” of a corrugation of the corrugated fin 4 .
  • connection segment 42 is formed with louvers 43 .
  • the corrugated fin 4 may be made of aluminum material. However, those having ordinary skill in the related art should appreciate that the invention is not limited to this.
  • connection segment 42 is a substantially straight segment. It should be appreciated that the invention is not limited to this.
  • connection segment 42 may also have an actuate shape.
  • FIG. 1 A portion of the corrugated fin 4 is shown in FIG. 1 . It should be appreciated that the corrugated fin 4 may have any suitable length in the longitudinal direction (i.e., an “up” and “down” direction in FIG. 1 ). In other words, the corrugated fin 4 may have any suitable number of corrugations.
  • louvers 43 are formed in each connection segment 42 .
  • the louver 43 may be formed by cutting and bending a certain portion of the connection segment 42 to form a vane 431 and an opening 432 .
  • a portion of the connection segment 42 is cut and turned-over from a surface of the connection segment 42 , in which “ ⁇ ” is a “louver” angle (i.e., an angle of inclination of the vane 431 with respect to the plane of the connection segment 42 , as shown in FIG.
  • “W” is an interval between adjacent louvers 43 (i.e., length of a substantially straight line between adjacent louvers 43 in a “transversal” direction to a “length” direction of the louver 43 )
  • “H 2 ” is a length of the louver 43 (i.e., a dimension of the louver 43 in a “right” and “left” direction in FIG. 1 )
  • “S” is a “vane” distance (i.e., distance of a straight line between the adjacent vanes 43 , as shown in FIG. 2 ).
  • a fin pitch “P” is a spacing between adjacent crest and trough (i.e., adjacent arc segments 41 ). In other words, the fin pitch “P” is a distance of a straight line between two points with the same phase relationship of the corrugated fin 4 in the longitudinal direction.
  • the heat exchanger is used as an evaporator, when the heat exchanger is the flat-plate-shaped heat exchanger and inclined with respect to a horizontal direction (as shown in FIG. 9 ) or a bent heat exchanger (as shown in FIG. 10 ), during operation or stoppage, the condensate on the surface of the corrugated fin 4 may directly drop from the surface of the corrugated fin 4 .
  • the condensate may be accumulated on the surface of the corrugated fin under the following conditions: 1) the smaller the radius “R” of the arc segment is, the greater the surface tension of the condensate is so that the condensate tends to be accumulated on the arc segment; 2) the smaller the fin pitch “P” of the fin is, the more condensate tends to accumulate between adjacent connection segments; and 3) the smaller the interval “W” between adjacent louvers is, the more condensate tends to accumulate between adjacent louvers.
  • the heat-exchange performance, air resistance, and accumulated water on the surface of the heat exchanger using the corrugated fin have direct relationship to the louver length “H 2 .”
  • 0 ⁇ H 2 ⁇ (H 1 ⁇ 2R+2R sin ⁇ )/cos ⁇ is set for preventing water from dropping downward from the fin, in which “H 2 ” is the louver length, “H 1 ” is the height of the fin, “R” is the radius of the arc segment, and “ ⁇ ” is the inclination angle of the connection segment.
  • the radius “R” shall be small enough. Considering actual use, there is a limit to decrease the radius “R,”—that is, the radius “R” cannot be decreased infinitely so that the condensate is unavoidable to accumulate on the arc segments 41 . Therefore, in an embodiment, the surface tension of water is increased, and the weight of the water is reduced.
  • the water may not drop directly from the arc segment 41 if the radius “R” is less than or equal to 0.85 mm.
  • the adsorption force shall be greater than or equal to the sum of the gravity of water and pushing force of the air to avoid dropping of the condensate from the arc segment 41 —that is, the radius “R” of the arc segment 41 shall be less than or equal to about 0.85 mm. Meanwhile, considering the machinability, in an embodiment, the radius “R” is greater than or equal to about 0.1 mm.
  • the adsorption force of the condensate on the arc segment 41 may be greater than the sum of the gravity of the condensate and pushing force of the air, thus avoiding dropping of the condensate from the arc segment 41 . Therefore, the water is prevented from dropping downward into the air pipe from the arc segment 41 .
  • connection segments 42 of the corrugated fin 4 if the condensate thereon may not be removed in time, it may drop from the connection segments 42 into the air pipe. In this way, the water leakage may occur in the unit using the heat exchanger, the air pipe may be corroded, and bacteria may breed in the corroded air pipe, thus shortening the service life of the unit and causing damage to human health.
  • connection segment 42 the inclination angle “ ⁇ ” of the connection segment 42 shall be big enough. Therefore, the condensate flows downward along the connection segment 42 and, consequently, into the water-collecting pan (not shown) along the tube 3 so that no water is accumulated on and dropped from the connection segment 42 . Meanwhile, the fin pitch “P” shall be large enough.
  • the fin pitch “P” is substantially larger than about 2.5 mm, no condensate presents between adjacent connection segments 42 .
  • the fin pitch “P” is substantially in a range of about 2.8 mm to about 7 mm.
  • the accumulated water between adjacent louvers 43 is mainly caused by the surface tension of water. If the vane distance “S” of the louver 43 is increased, the surface tension of water between the adjacent louvers 43 may be reduced or eliminated, thus decreasing or eliminating the accumulated water between the adjacent louvers 43 .
  • the corrugated fin 4 according to an embodiment of the invention, the water-drainage performance is improved, and dropping of the condensate into the air pipe from the surface of the heat exchanger using the corrugated fin 4 may be reduced or eliminated, thus prolonging the life of the unit and reducing the harm of the bacteria.
  • the heat exchanger according to an embodiment of the invention includes a first header 1 , a second header 2 , tubes 3 , and corrugated fins 4 .
  • the second header 2 is spaced apart from and substantially parallel to the first header 1 .
  • the tubes 3 are arranged and spaced apart from each other in a direction substantially parallel with the axial direction of the first and second headers 1 , 2 .
  • Two ends of each tube 3 are connected respectively to the first and second headers 1 , 2 to communicate the first and second headers 1 , 2 .
  • the fins 4 are disposed between adjacent tubes 3 , in which the corrugated fins 4 may be ones described with reference to the above embodiments.
  • the tube 3 may be a flat tube.
  • the shape of the cross-section of the tube 3 may be a rectangle, an oblong presenting flat sides interconnecting two round ends, or a flat ellipse.
  • the heat exchanger may have a flat-plate shape.
  • the heat exchanger When used as an evaporator, the heat exchanger is inclined with respect to the horizontal plane, and, as shown in FIG. 9 , air blows from an air outlet to the surface of the heat exchanger in a direction “A.” As described above, because no condensate drops, performance of the heat exchanger may not be influenced, the heat exchanger may not be damaged, and harm of the bacteria may be avoided.
  • the heat exchanger has a bent structure.
  • each tube 3 includes two substantially straight segments 31 and a bent segment 32 connected between and twisted relative to the two straight segments 31 by a predetermined angle.
  • each fin 4 is only disposed between adjacent straight segments 31 . In other words, no fins are disposed between adjacent bent segments 32 .
  • the heat exchanger having a bent structure is not limited to the above embodiments.
  • the bent heat exchanger may be formed by two flat-plate-shaped heat exchangers connected in series via a connecting pipe and forming a certain intersection angle therebetween.
  • the heat-exchanger portions on two sides are inclined at a certain angle with respect to the horizontal plane, and, as shown in FIG. 10 , air blows from an air outlet to the heat exchanger in a direction “A.”
  • air pipe may not be corroded, and bacteria may not breed in the corroded air pipe, thus lengthening the life of the unit (such as an air conditioner) without causing damage to human health.
