The specific embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described further.
As shown in Figure 1, the heat exchanger 10 according to embodiment of the present utility model comprises: arrange heat exchanger core body (only showing two rows among the figure), these many row's heat exchanger core bodies comprise row's heat exchanger core body 13 and another row's heat exchanger core body 11 more.Air stream A is from a side direction heat exchanger 10 air-supplies of heat exchanger 10, and these many row's heat exchanger core bodies also comprise cold-producing medium open communication 15 and 17.Described row's heat exchanger core body 13 and described another row's heat exchanger core body 11 promptly in the orientation of described row's heat exchanger core body 13 and described another row's heat exchanger core body 11, can roughly be in alignment with each other on the width of heat exchanger core body.
Shown in Fig. 2,3a and 3b, described row's heat exchanger core body 13 comprises radiating tube 131 and the fin between radiating tube 131 133.Equally, described another row heat exchanger core body 11 comprise radiating tube 111 and the fin between radiating tube 111 113.The radiating tube 111 of the radiating tube 131 of described row's heat exchanger core body 13 and described another row's heat exchanger core body 11 is equidistantly arranged.The spacing of the radiating tube 131 of described row's heat exchanger core body 13 is less than the spacing of the radiating tube 111 of another row's heat exchanger core body 11.It is great that described row's heat exchanger core body 13 and described another row's heat exchanger core body 11 are set to the shared proportion of gaseous refrigerant in the cold-producing medium of a described row in the heat exchanger core body 13 ratio more shared than the gaseous refrigerant in the cold-producing medium in described another row's heat exchanger core body 11.Described another row's heat exchanger core body 11 can be in windward side, i.e. upstream side on the direction of air stream A.
Select the less core of flat tube spacing for use by gaseous area, can under identical core body height, increase flat tube quantity, thereby reach bigger internal volume, reduce the resistance of cold-producing medium in the flat tube internal flow.For the bigger zone of liquid refrigerant proportion, then adopt the bigger core body of flat tube spacing, identical core size, then flat tube quantity can be less, also can obtain higher cold-producing medium flow velocity, increases its heat exchange efficiency.
According to embodiments of the invention, shown in Fig. 2,3a and 3b, a plurality of radiating tubes 131 in the radiating tube of a plurality of radiating tubes 131 in the radiating tube of described row's heat exchanger core body 13 and described another row's heat exchanger core body 11 can align mutually, promptly arrange in the orientation of heat exchanger core body 11 and can align mutually at described row's heat exchanger core body 13 and described another.Thus, can realize: 1, reduce the cold-producing medium flow resistance; 2, reduce the air flow resistance; And 3, improve the flow velocity of cold-producing medium, increase at least one in the coefficient of heat transfer.
According to one embodiment of the present invention, as shown in Figure 2, the relation of the spacing L1 of the radiating tube 131 of the spacing L2 of the radiating tube 111 of described another row's heat exchanger core body 11 and described row's heat exchanger core body 13 is L2=n * L1, and wherein n is the integer greater than 1.
As selection, shown in Fig. 3 a and 3b, the relation of the spacing L1 of the radiating tube 131 of the spacing L2 of the radiating tube 11 of described another row's heat exchanger core body 11 and described row's heat exchanger core body 13 is L2=[(n+2)/(n+1)] * L1, wherein n is a positive integer.Shown in Fig. 3 a, when n=1, L2=1.5 * L1.The radiating tube 111 of described another row's heat exchanger core body 11 is every a radiating tube, and just the radiating tube 131 with described row's heat exchanger core body 13 aligns.Shown in Fig. 3 b, when n=2, L2=1.33333 * L1, the radiating tube 111 of described another row's heat exchanger core body 11 are every two radiating tubes, and just the radiating tube 131 with described row's heat exchanger core body 13 aligns.
Can reduce of the influence of radiating tube front face area by said structure, can reduce windage thus and improve air quantity windage.
Among Fig. 1,2,3a, the 3b, only show two row's heat exchanger core bodies, heat exchanger 10 can comprise the two row or multi-row heat exchanger core body, and described row's heat exchanger core body 13 and described another row's heat exchanger core body 11 can be adjacent one another are, or be separated from each other, for example, has a row or multi-row heat exchanger core body in the middle of described row's heat exchanger core body 13 and described another row's heat exchanger core body 11.In addition, described row's heat exchanger core body 13 and described another row's heat exchanger core body 11 also can not be outermost heat exchanger core bodies.
Though in conjunction with the accompanying drawings the utility model is illustrated, disclosed embodiment is intended to the utility model preferred implementation is carried out exemplary illustration in the accompanying drawing, and can not be interpreted as a kind of restriction of the present utility model.For example, the scheme in the foregoing description can make up mutually.
