20150283657 | MANUFACTURING METHOD FOR HEAT EXCHANGER AND DEVICE THEREFOR, AND AIR CONDITIONER AND/OR EXTERNAL UNIT THEREOF EQUIPPED WITH HEAT EXCHANGER MANUFACTURED USING SAID METHOD - The present invention provides manufacturing method of a heat exchanger that, even if the position of a tube opening portion of a tube of a heat exchanger for which tube expansion is conducted, varies depending on the type of a heat exchanger, a mechanism adjusting the stop position of a flare plate as well as any complicated adjusting work therefor are not necessary and a heat exchanger in which flares in the same shape and in constant certain depth are formed at an opening portion of a tube of various kinds of heat exchangers having different total lengths in the longitudinal direction, and a device for a heat exchanger manufacturing method, and an air conditioner and/or outdoor unit thereof equipped with a heat exchanger manufactured using said manufacturing method. | 10-08-2015 |
20150273562 | TUBE EXPANSION DEVICE - The present invention provides a tube expansion device which can prevent decreases in productivity by causing only side regulating bodies to be moved easily and surely, even if the left and right ends of a heat exchanger increases or decreases, or the thickness of a heat exchanger is increased because an insertion tube becomes multiple columns from single column; and, in the case of tube expansion for a heat exchanger in long total length, and even if an expanding and a contracting rod of a cylinder which are reciprocating movement means of a reference platform or a rod-shaped male screw momentarily receives the weight of a stripper plate itself through said reference platform, can prevent deflection and breakage of said expanding and contracting rod and said rod-shaped male screw and breakage of cylinder's seal portion or breakage, etc. of a screw thread by supporting a reference platform at multiple points. | 10-01-2015 |
20150084259 | HOLDER FOR PIPE IN HEAT EXCHANGER, METHOD AND DEVICE FOR MANUFACTURING HEAT EXCHANGER USING SAID HOLDER, AND AIR CONDITIONER AND/OR OUTDOOR UNIT HAVING SAID HEAT EXCHANGER - The current invention provides a tube-grasping body for grasping an insert tube in a heat exchanger, and heat exchanger production methods and apparatuses utilizing the tube-grasping body, wherein the tube-grasping body enables to enlarge and connect an insert tube to a heat radiating fin for producing a heat exchanger, still keeping the total length of insert tubes at an almost same level even after the enlargement; and the tube-grasping body is connected at its exterior to the guide-pipe. | 03-26-2015 |
20140124184 | MANUFACTURING METHOD FOR GRIP MEMBER FOR INSERTION TUBE IN HEAT EXCHANGER, MANUFACTURING METHOD FOR HEAT EXCHANGER USING SAID GRIP MEMBER, AND AIR CONDITIONER AND/OR OUTDOOR UNIT HAVING SAID HEAT EXCHANGER - The current invention provides a tube-grasping body for grasping an insert tube in a heat exchanger, and heat exchanger production methods and apparatuses utilizing the tube-grasping body, wherein said tube-grasping body enables to enlarge and connect an insert tube to a heat radiating fin for producing a heat exchanger, still keeping the total length of insert tubes at an almost same level even after the enlargement; and said tube-grasping body is connected at its exterior to the guide-pipe. | 05-08-2014 |
20120279695 | HOLDER FOR PIPE IN HEAT EXCHANGER, METHOD AND DEVICE FOR MANUFACTURING HEAT EXCHANGER USING SAID HOLDER, AND AIR CONDITIONER AND/OR OUTDOOR UNIT HAVING SAID HEAT EXCHANGER - The current invention provides a tube-grasping body for grasping an insert tube in a heat exchanger, and heat exchanger production methods and apparatuses utilizing the tube-grasping body, wherein the tube-grasping body enables to enlarge and connect an insert tube to a heat radiating fin for producing a heat exchanger, still keeping the total length of insert tubes at an almost same level even after the enlargement; and the tube-grasping body is connected at its exterior to the guide-pipe. | 11-08-2012 |
