が提案されている。As this type of heat exchanger, as shown in FIG. 3, continuous fins 53 of two different lengths are arranged in a straight pipe portion of a meandering refrigerant tube 51.
In the straight pipe portion of the meandering refrigerant tube 51, three long, medium, and short lengths are successively arranged in the airflow direction by shifting the arrangement pitch from sparse to dense in two stages, as shown in FIG. There has been proposed a configuration in which fins 55 are arranged and the arrangement pitch of the continuous fins 55 is shifted from sparse to dense in three stages in the airflow direction.

低下するという問題がある。By the way, in order to prevent a so-called bridge from being formed in the frost-prone area on the air inflow side, the continuous fins are constituted by fins 55 having at least three types of long, medium and short lengths. Then, it is desirable that the arrangement pitch of the continuous fins 55 be divided into several stages in the airflow direction and arranged sparsely and densely. However, in order to form a continuous fin with three or more types of fins having different lengths, it is necessary to manufacture continuous fins of several types in length, which causes a problem that production efficiency is reduced.

In the first part, the pits formed between the long continuous fins 5a are formed.
Is substantially equal between the continuous fins 5a, and
In short, the continuous fin 5b and the long piece of short piece shifted to the air inflow side
The pitch formed between the continuous fins 5a is
Are almost equal, and all the continuous
The pitch formed between the fins 5a and 5b is
And are formed almost equally.

４段階に分けて配列される。Therefore, as shown in FIG. 1, the arrangement pitch of the continuous fins 5 arranged in the straight pipe portion 1a of the refrigerant tube 1 is divided into two stages so as to be sparse and dense in the air flow direction. . The short continuous fins 5b can be shifted in arbitrary steps. For example, if the continuous fins 5b are shifted in two stages in the longitudinal direction, the arrangement pitch of the continuous fins 5 is divided into three stages so as to be sparse and dense in the airflow direction, and the continuous fins 5b are divided into three stages. If it is shifted, the arrangement pitch of the continuous fins 5 is divided into four stages so as to be sparse to dense.

可能になる。As described above, according to this embodiment, it is as if the continuous fins 5a and 5b having three or more types of lengths are prepared by merely preparing the continuous fins 5a and 5b having two types of lengths. In addition, it is possible to arrange the continuous fins 5 in several stages so that the arrangement pitch is sparse to dense in the airflow direction.
【００１７】ところでこの種の冷蔵庫用のエバポレータ
においては、気流入側の領域における連続フィン５の板

Even if it is obtained and the frost grows over time, so-called bridges and the like are not formed there, and the flow on the air side there is not hindered, and thus the efficiency on the air side is improved. It does not decline.

The arrangement pitch of the fins can be arranged in several stages so as to be sparse to dense in the airflow direction, so that the management is extremely easy in the production management of the fins, thus improving the production efficiency of the heat exchanger. In addition, the generation of a bridge can be reliably prevented. According to this embodiment, on the air outflow side of the short piece continuous fin 5b shifted to the air inflow side, the heat transfer area is reduced by the amount shifted.
Even if the heat transfer effect at this portion is sacrificed, a still greater effect can be obtained.
