Embodiment approach 1

[0041] In the heat exchanger according to Embodiment 1, fin pitches in some ranges are formed to be larger than fin pitches in other ranges by an assembling method different from conventional ones in which fin pitches can be easily changed. In addition, the air conditioner according to the first embodiment includes the heat exchanger according to the first embodiment in which the fin density is optimally arranged in consideration of the internal structure of the case, and can achieve energy saving and low cost while maintaining performance equivalent to conventional ones. Cost, low price.

[0042] Hereinafter, the heat exchanger according to Embodiment 1, the method of manufacturing the heat exchanger according to Embodiment 1, and the air conditioner according to Embodiment 1 will be described in detail. In addition, below, the air conditioner of this Embodiment 1 is demonstrated taking the outdoor unit which mounted the heat exchanger of this Embodiment 1 as an example.

Embodiment approach 2

[0082] In Embodiment 1, as an example of changing the fin pitch in a part of the range of the heat exchanger 1 , an example of changing the fin pitch in the compressor housing adjacent range 5 close to the compressor housing 7 was described. However, the range of changing the fin pitch is not limited to the compressor housing adjacent range 5 . It is also possible to vary the fin spacing of the heat exchanger 1 in the following ranges together with the compressor housing adjacent range 5 or separately from the compressor housing adjacent range 5 . In addition, in this Embodiment 2, about the structure which is not described especially, it is the same as Embodiment 1, and the same code|symbol is used for the same function and structure.

Embodiment approach 3

[0093] The example of changing the fin pitch in a part of the range of the heat exchanger 1 is not limited to that shown in Embodiment 1 and Embodiment 2, and may be combined with or different from the structure of at least one of Embodiment 1 and Embodiment 2. From the structure of Embodiment 1 and Embodiment 2, the fin pitch of the heat exchanger 1 is changed in the following range. In addition, in Embodiment 3, the configurations not particularly described are the same as in Embodiment 1 or Embodiment 2, and the same functions and configurations are described using the same reference numerals.

Abstract

The invention discloses a manufacture method for a heat exchanger and a manufacture method for an air conditioner. The heat exchanger (1) comprises multiple fins (12) which are stacked at specified fin intervals and multiple heat conduction pipes (10) of which cross sections are flat; the heat conduction pipes (10) penetrate through the fins (12) along the stacking direction; multiple notches (13) which correspond to the cross sections of the heat conduction pipes (10) in shape are formed in the end parts of the length direction sides of the fins (12); a flange (14) is arranged on the edge of each notch (13); the heat conduction pipes (10) are inserted into the notches (13); fin intervals among a part of the multiple fins (12) are larger than fin intervals among the other fins (12); and the larger fin intervals at least are larger than the heights of the flanges (14).

Description

[0001] This application is an invention patent with the international application number PCT / JP2012 / 005041, the international application date is August 8, 2012, the national application number is 201280073564.7, and the invention name is "heat exchanger and air conditioner equipped with the heat exchanger" Divisional application of the application. technical field [0002] The present invention relates to a method of manufacturing a heat exchanger and a method of manufacturing an air conditioner. Background technique [0003] Conventionally, heat exchangers of air conditioners have mostly adopted a flat-finned tube structure in which a plurality of plate-shaped aluminum fins with circular holes formed therein are stacked at predetermined fin pitches. Insert a plurality of copper or aluminum heat transfer tubes with a circular cross-section in the stacking direction of the fins (hereinafter, also referred to as fin groups), and then use a hydraulic or mechanical tube expande...
