Abstract
The utility model discloses a heat exchanger. The heat exchanger comprises multiple fin combinations. Each fin combination comprises multiple rows of fin modules. Each fin module comprises fins and heat exchange pipes. Each fin is provided with multiple mounting holes aligned at the laminated direction of the fins along the length direction. The height of each mounting hole is the fin distance of each fin. The multiple fins are separated with each other by fin distances of the fins and a row is formed by lamination. The heat exchange pipes sequentially penetrate through the mounting holes of the fins along the laminating directions of the fins. The heat exchanger is characterized in that: a fin disposed first in each row of each fin module is a first fin; the fin distance of each first fin is different in each row of fin module in each fin combination; by adjusting the fin distance of each first fin of each row of fin module in each fin combination of the heat exchanger, each row of fins are arrayed in a staggering and overlapping mode in a length direction; when air flow passes through gaps of the fins, the direction of the air flow no longer parallelly flows in and out with the gaps of the heat exchanger; a flow path is changed into a staggering and overlapping path and a turbulent flow is formed; and due to the fact that the path that air flow flows becomes longer, the air flow stays longer on the surfaces of the fins so that heat exchanger is more fully conducted .

The specific embodiment
The first embodiment
As Fig. 1, shown in Fig. 2, heat exchanger comprises multiple fin combinations, fin combination comprises many row's fin modules, fin module has multiple fins 1 and is arranged on the heat exchanger tube 2 on fin 1, it is in a row that the mode that multiple fins 1 pass through according to gas is spaced from each other interval the stacked arrangement of regulation, as Fig. 3, shown in Fig. 4, single fin is rectangle conventionally, on each fin 1, punching stretch goes out multiple installing holes 11 of aiming at along fin 1 stacked direction along its length, the height A of described installing hole 11 is fin pitch of fins A, distance between adjacent fins 1 is fin pitch of fins A, heat exchanger tube passes along fin 1 stacked direction each installing hole 11 aligning successively, the two ends of heat exchanger tube 2 are arranged on installs on backplate 3, the end of adjacent heat exchange tubes 2 is communicated with by elbow, so repeat, heat exchanger tube 2 is arranged on fin 1 by roundabout reciprocal mode, and form to arrange the fin module as unit.
In the present embodiment, as shown in Figure 6, each fin combination comprises three row's fin modules, by adjusting a pitch of fins for first fin in every row's fin module, it is the height of installing hole 11, realize folded arrangement of mistake of fin between row and row, wherein a pitch of fins for the first fin 41 of first row fin module 4 is A, the distance that is first fin 41 distance installation backplates 3 of first row fin module 41 is A, the A that a pitch of fins for the first fin 51 of second row fin module 5 is 1/3, the A that the distance that is first fin 51 distance installation backplates 3 of second row fin module 5 is 1/3, the A that a pitch of fins for the first fin 61 of the 3rd row's fin module 6 is 2/3, the A that the distance that first fin 61 distances of the 3rd row's fin module 6 are installed backplate 3 is 2/3, in fin module, a pitch of fins for all the other fins 1 is A, so design, three row's fin modules form a fin combination, in heat exchanger, there are multiple fin combinations, fins set is combined in the process of arrangement, as shown in Figure 5, every row's fin is wrong folded arrangement in the direction of fin block length, when air-flow passes through fin 1 gap, airflow direction is by no longer parallel with heat exchanger gap turnover, the route of flowing through becomes wrong folded route, form turbulent flow, because of the route of airflow passes elongated, the time lengthening that air-flow stops on fin 1 surface, heat exchange is more abundant.
