Abstract
The utility model discloses a heat exchange sheet of a heat exchanger. The heat exchange sheet of the heat exchanger comprises a base plate, the surface of the base plate is in a wave shape, a plurality of through holes are formed in the base plate and matched with a refrigerant pipeline, and a plurality of louver structures are arranged round the through holes in the base plate. Due to the fact that the louver structures are arranged on the wave-shaped base plate, air flows through a trough of the base plate and can flow to the other side of the base plate through gaps between adjacent louver pieces of the louver structures, an airflow eddy is prevented form being formed, meanwhile due to the change of the airflow direction, the flowing of airflow is in a turbulent state, the he heat exchange sheet of the heat exchanger is beneficial to heat transmission between the refrigerant pipeline and the airflow, and heat exchange efficiency of the heat exchange is improved.

Technical field
The utility model relates to the technical field of air-conditioner in electric equipment, is specifically related to the heat exchanger fin that a kind of air-conditioner is used heat exchanger, belongs to the improvement technology of the heat exchanger fin of heat exchanger.
Background technology
Fin-tube type heat exchanger range of application on the family expenses air-conditioning is quite extensive.Wherein crack sheet, louvre blade, these 3 kinds of heat exchanger fins of corrugated plate is the most common, and to shown in Figure 6, in figure, arrow is airflow direction as Fig. 1, but various forms of heat exchanger fin has pluses and minuses separately.
The sheet that cracks as shown in Figure 1, 2, owing to having opened a lot of seams on heat exchanger fin, every seam plays breakaway action to the generation in the boundary layer of air-flow.By thermal conduction study as can be known, the existence of flow boundary layer air will increase thermal resistance, reduce heat transfer.The existence of seam, the generation of the flow boundary layer air of destruction reduces thermal resistance, makes heat exchanger play the effect of augmentation of heat transfer.But due to the dissection of every seam to air-flow, increased flow resistance, under the evaporation operating mode, fin surface has the existence of condensed water, and the air current flow resistance is further strengthened, and is unfavorable for the operation of low-temperature evaporation operating mode especially.
Louvre blade as shown in Fig. 3,4, the existence of blinds can change the flow direction of air-flow, makes air current flow be in turbulent condition, and by hydrodynamics as can be known, turbulent flow is conducive to the heat transfer of fluid, and this heat exchanger fin has good heat transfer property under declared working condition.But because there are certain angle in blinds and air-flow, usually 25 ° of left and right, flowing of the air-flow that stops strengthened flow resistance, is unfavorable for equally the operation of low-temperature evaporation operating mode.
Corrugated plate as shown in Fig. 5,6, general and airflow direction has certain angle due to bellows folds, airflow direction there is certain change effect, but change little, louvre blade to relative Fig. 3 of flow resistance of air-flow reduces to some extent, is conducive to the operation of low-temperature evaporation operating mode, but under declared working condition, owing to easily forming air-flow whirlpool (B) on bellows folds, make the heat exchanger fin decrease in efficiency.
