Definitions
- the present invention relates to a heat exchanger, and more particularly to a heat exchanger suitable for use in an air conditioner, a refrigerator, an ice maker or the like.
- the heat exchange there is one that forms a heat exchange by dividing a perforated fin with a perforation formed by the perforation. Specifically, in this heat exchange, a heat transfer tube is passed through the insertion hole of the fin in which the perforation is formed, and the fin is separated at the perforation to form two heat exchanges. Yes.
- the above conventional heat exchanger can divide the fins at the perforations, so that it is easy to manufacture and can be separated at the perforations or left without being separated. If the heat exchange can be easily manufactured, it has the advantage.
- the conventional heat exchange has the advantage that the dimensional setting of the fin is easy to change, the perforation in the fin formed by dividing the perforated fin is divided. Since the burr is formed at the outer edge corresponding to the portion where the heat is formed, the condensed water (condensate) generated in the fin during the use of the heat exchanger passes through this burr to the fin. There is a problem of power scattering. In particular, when the conventional heat exchange is used as a heat exchanger on the indoor side of an air conditioner, the condensed water is scattered into the room due to air blowing, which becomes a serious problem.
- the conventional heat exchange has a problem in that the aesthetic appearance of the heat exchange is impaired because the edge with the burr is positioned on the outer edge of the heat exchange.
- an object of the present invention is to provide heat exchange in which the fin size setting is easy to change and the fin force condensation water is scattered so as not to impair the beauty.
- a heat exchanger according to the present invention provides:
- a first heat exchange section having a plate-like first fin and a plurality of first heat transfer tubes inserted through the first fin so as to extend in the thickness direction of the first fin;
- a second heat exchanging portion having a plate-like second fin and a plurality of second heat transfer tubes inserted through the second fin so as to extend in the thickness direction of the second fin!
- At least one edge of the first fin and the second fin has a plurality of burrs at a predetermined interval
- the first heat exchanging part and the second heat exchanging part are applied to the edge force of the burr of at least one of the first fin and the second fin against the other edge of the first fin or the second fin. It is characterized in that the edge with the burr is located on the inside, arranged so as to meet each other in contact or direction.
- an edge where the burr of at least one of the first fin and the second fin is in contact with or opposite to the other edge of the first fin or the second fin. Since the edge with the burr is located on the inside, the edge with the groove is on the edge of the first fin other than the edge that contacts or faces the second fin. There is no edge, and the edge where the groove exists is not on the edge other than the edge that contacts or faces the first fin at the edge of the second fin.
- the edge of the first fin does not exist on an edge other than the edge that abuts or is directed against the second fin, and the edge having the groove is Since the edge of the second fin is not in contact with the first fin at the edge of the first fin, or on the edge other than the opposite edge, the burr is not located outside the edge force heat exchange ⁇ . Therefore, according to the present invention, the beauty of heat exchange is not impaired. The invention's effect
- an edge having at least one burr of the first fin and the second fin is in contact with or directed to the other edge of the first fin or the second fin. Since the edge where the burr is located is located on the inside, even if condensed water scatters from the edge where the burr is located, the edge where the burr abuts or has directing force Thus, the scattered condensed water can be received and the condensed water can be prevented from splashing outside together with the wind. Therefore, even if the heat exchanger of the present invention is used as a heat exchanger on the indoor side of the air conditioner, the condensed water mixed in the wind can be prevented from scattering into the room.
- the edge with the burr is not positioned outside the heat exchanger, and the aesthetic appearance of the heat exchanger is not impaired.
