Embodiment Construction

[0022] One embodiment will be described with reference to the drawings.

[0023] figure 1 It is a figure which shows the schematic structure of the refrigeration cycle apparatus 1 concerning this embodiment. The refrigerating cycle apparatus 1 is, for example, an air conditioner capable of cooling operation and heating operation, and includes a compressor 2, a four-way valve 3, an outdoor heat exchanger 4, an expansion valve 5, an indoor heat exchanger 6, and a system for connecting these elements. Refrigerant flow path 7.

[0024] The compressor 2 includes a compressor body 2a and an accumulator 2b. The accumulator 2b separates the refrigerant supplied through the refrigerant passage 7 into gas and liquid, and supplies the gas refrigerant to the compressor main body 2a. The compressor body 2a compresses the gas refrigerant supplied from the accumulator 2b to generate a high-temperature and high-pressure gas refrigerant.

[0025] In such a refrigeration cycle apparatus 1 ,...

Abstract

A method for manufacturing a heat exchanger according to an embodiment comprises first to third steps. The heat exchanger is provided with a plurality of flat pipes which are arrayed in a first direction and are longer in a second direction, and a plurality of plate fins which are arrayed in the second direction and are longer in the first direction. Each of the plate fins has a plurality of first slits that are open on one side along the first direction, and the flat pipes are passed through the first slits of the plate fins. In the first step, the plurality of flat pipes are arrayed in the first direction. In the second step, the plate fins are attracted by means of a suction member. In the third step, the plate fins attracted by means of the suction member and the flat pipes are relatively moved in a third direction, and the flat pipes are positioned in the first slits of the plate fins.

Description

technical field [0001] Embodiments of the present invention relate to a method of manufacturing a heat exchanger. Background technique [0002] Conventionally, there is known a heat exchanger including: a plurality of flat tubes having refrigerant flow paths inside; and a plurality of plate fins having slits having a shape corresponding to the plurality of flat tubes. , each flat tube passes through the groove of each plate fin. [0003] For example, when manufacturing such a heat exchanger, first, a plurality of plate fins are arranged at a predetermined pitch, and flat tubes are sequentially inserted into the grooves of the respective plate fins. In addition, headers are attached to both ends of each flat tube, and each flat tube and each plate fin are joined by brazing in a furnace. In the case of such a manufacturing method, when the flat tube is inserted into the grooves of the plurality of plate fins, there is a possibility that the plate fins may fall due to the fri...
