A device for inserting flat tubes into heat exchanger fins

Abstract

An object of the present invention is to provide an apparatus for inserting flat tubes into fins for a heat exchanger capable of efficiently assembling a core portion of a heat exchanger with good yield. As a solution, the device for inserting a flat tube into a fin for a heat exchanger includes: a fin stack arrangement part (120) for disposing a fin stack that is stacked in a plate thickness direction for heat exchange; Fins (10) for the device and inserting the guide body (G) into at least one notch (12); the flat tube setting part (130), which is relatively not inserted into the notch (12) ) to hold the flat tube (T) in an intermittent configuration; the flat tube insertion drive part (140), which inserts the flat tube (T) into the notch (12); the abutment plate (150), which is used to obtain The reaction force when the flat tube (T) is inserted into the notch (12); and the intermittent insertion of the flat tube into the fin laminate installation part (170), which separates the position of the notch (12) into which the flat tube (T) is not inserted and The positions of the flat tubes (T) of the flat tube installation part (130) are aligned, and the flat tubes are intermittently inserted into the fin stack installation part (170) for use by replacing the fin stack placement part (120).

Description

technical field [0001] The present invention relates to a device for inserting a flat tube into a heat exchanger fin, which is used for passing a flat tube through which a heat exchange medium for heat exchange flows in a state where a plurality of heat exchanger fins are stacked together. The tube is inserted into the notch of the heat exchanger fin in which a plurality of notches are formed from one side to the other side in the width direction. Background technique [0002] The core of a heat exchanger such as a cooler has tubes through which a heat exchange medium flows and heat exchanger fins (hereinafter simply referred to as fins) for substantially increasing the surface area of ​​the tubes. The core of such a heat exchanger is manufactured by assembling separately manufactured tubes and fins into one body. As a manufacturing apparatus of such a heat exchanger, for example, a configuration disclosed in Patent Document 1 is known. [0003] The core manufacturing devi...

AI Technical Summary

Problems solved by technology

If the flat tubes are to be inserted into all these notches at once, the frictional force acting on the fins will increase, and the pressing force when inserting the flat tubes will have to be increased, and there is a problem of increasing the size of the drive unit and increasing the manufacturing cost.
