Abstract
A heat exchanger includes a flat tube and a fin that is formed in an elongated plate shape and that includes a fin slit formed by notching the fin in a direction orthogonal to a longitudinal direction of the fin. A manufacturing device for manufacturing the heat exchanger includes an insertion head configured to move up and down in order to insert the flat tube held by the insertion head into the fin slit from above the fin, and a support. The support is configured to support, from below, the flat tube held by the insertion head.
Claims4
A manufacturing device for manufacturing a heat exchanger including a flat tube and a fin that is formed in an elongated plate shape and that includes a fin slit formed by notching the fin in a direction orthogonal to a longitudinal direction of the fin, the manufacturing device comprising:
- an insertion head configured to move up and down in order to insert the flat tube held by the insertion head into the fin slit from above the fin, the insertion head including a lower surface having a plurality of grooves configured to receive upper portions of the flat tube;
- and
- a support configured to support, from below, the flat tube held by the insertion head, the support including opposing support arms configured to support outer portions of the flat tube when the flat tube is received by the grooves of the insertion head,
- the fin including a plurality of fins arranged in the direction orthogonal to the longitudinal direction, and
- the support supporting, from below, the outer portions of the flat tube when the flat tube is arranged on the plurality of fins, such that when viewed from above, the outer portions of the flat tube are located outside of two of the fins each located at a respective one of both ends of the flat tube in the direction in which the plurality of fins are arranged.
A manufacturing device for manufacturing a heat exchanger including a flat tube and a fin that is formed in an elongated plate shape and that includes a fin slit formed by notching the fin in a direction orthogonal to a longitudinal direction of the fin, the manufacturing device comprising:
- an electronic controller configured to control
- an insertion head to move up and down in order to insert the flat tube held by the insertion head into the fin slit from above the fin;
- and
- a support to support, from below, the flat tube held by the insertion head,
- the fin including a plurality of fins arranged in the direction orthogonal to the longitudinal direction, and
- the electronic controller being further configured to control the support to support, from below, outer portions of the flat tube when the flat tube is arranged on the plurality of fins, such that when viewed from above, the outer portions of the flat tube are located outside of two of the fins each located at a respective one of both ends of the flat tube in the direction in which the plurality of fins are arranged.
