本発明は熱交換器の製作法に係り、長幅フィンと短幅フ
ィンを交互に積み重ねフィン端面が千鳥となる熱交換器
の簡単な製作法である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a heat exchanger, and is a simple method for manufacturing a heat exchanger in which long width fins and short width fins are stacked alternately so that the fin end faces are staggered.

り、また機械化しても生産速度が遅くかつ装置が複雑に
な−り高価であるなどの欠点があった。Conventionally, the manufacturing method of a heat exchanger with a large fin pitch and staggered fin end faces, such as an evaporator for a refrigerator, is to mold fins of different widths and then alternately arrange these fins into a comb-shaped aligned layer. The insertion and assembly method is known as a known technique. Most of these manufacturing methods rely on manual labor, and even when mechanized, the production speed is slow and the equipment is complicated and expensive.

ィンを用いる構造の熱交換器で、フィン端面を千鳥にす
ることは公知技術では製作が不可能であった。Therefore, in a heat exchanger for a room air conditioner, which has a structure in which the fin pitch is secured by the curl height of the pipe insertion hole and uses many fins, it is impossible to manufacture the fin end faces in a staggered manner using known technology. It was possible.
本発明の目的は、長幅フィンと短幅フィンを交互に積み
重ねてフィン端面が千鳥となる熱交換器を、簡単で高い
生産性のある方法で製作する方法を、提供することにあ
る。An object of the present invention is to provide a simple and highly productive method for manufacturing a heat exchanger in which long-width fins and short-width fins are alternately stacked and the fin end faces are staggered.

く清潔であること等により普及率が急激に増大している
。The present invention has been made with attention to the following points. child\
Over the past few years, the popularity of HEATBOPP type room air conditioners has rapidly increased due to their improved heating capacity, which has made them more economical than other heating devices, as well as their high safety and cleanliness.

放熱し、キャビラリーチー−プ４、室外熱交換器３へと
冷媒が循環するしくみになっている。Generally, a heat pump type room air conditioner is an air conditioner that uses a four-way valve 2 to change the flow of refrigerant, as shown in FIG. 1, and can perform cooling in the summer and heating in the winter. In the heating operation, outdoor heat is absorbed by the outdoor heat exchanger 3, pumped up by the compressor 1 through the four-way valve 2, and then radiated indoors by the indoor heat exchanger 5. The refrigerant is circulated to the heat exchanger 3.

温度が低いため達外熱交換器に霜が付き、このため風量
が減少し暖房能力を著るしく低下させる。With improvements in heating capacity, the use of heat pump room air conditioners has expanded to include colder regions. Frost forms, which reduces air volume and significantly reduces heating capacity.
通常室外熱交換器に付いた霜は、約１時間に１回の頻度
で冷媒の流れを逆転させ高温のガス冷媒を、室外熱交換
器に渚って、霜取りを行なっている。Normally, frost on the outdoor heat exchanger is removed by reversing the flow of the refrigerant approximately once every hour and transferring high-temperature gas refrigerant to the outdoor heat exchanger.

が良いとされている。Therefore, heating cannot be performed for the few minutes to 10 minutes it takes to defrost and remove the frost, which is a major disadvantage of heat pump room air conditioners. as,
It is said that it is best to have a rough fin pitch on the ventilation and air inlet side of the heat exchanger, and then gradually narrow the fin pitch so that the fin end faces are staggered.

せることが確認されている。This type of heat exchanger structure can significantly extend the time it takes for the fins to become clogged with frost and reduce airflow. Experiments have shown that if the fin end face on the ventilation inlet side of an outdoor heat exchanger is arranged in a 2-4 U+ staggered arrangement, the frost distribution can be improved and the defrosting interval time can be extended by approximately 1.5-2.0 times compared to conventional defrost intervals. has been confirmed.

制御を変更するだけでこの様な熱交換器の製作を可能と
するものであり、非常に有益、安価な製作法である。However, the present invention has not been put to practical use because there is no economical method for manufacturing a heat exchanger that does not produce fin scraps, has high productivity, and has staggered fin end faces using an inexpensive device. It is possible to manufacture such a heat exchanger by simply changing the width cutting unit and its control in the fin forming process, and it is a very useful and inexpensive manufacturing method.
