Embodiment Construction

[0025] (1) Overall structure

[0026] Such as figure 1 As shown, the refrigerant flow divider 10 is applied to, for example, the heat exchanger 1 on the heat source side included in the air conditioner. Although not shown in the figure, in addition to the heat exchanger 1 on the heat source side, the air conditioner also includes, for example, a heat exchanger on the utilization side for performing a vapor compression refrigeration cycle, and is connected with the heat exchanger on the heat source side. heat exchangers 1 in a pair; a compressor that circulates the refrigerant flowing in the heat exchanger 1 on the heat source side and the heat exchanger on the utilization side; a four-way valve that switches the flow of the refrigerant; and a blower fan, etc., which generate an air flow to the heat exchanger 1 . The air conditioner is configured, for example, to switch between a cooling operation and a heating operation, and the direction of the refrigerant flowing through t...

Abstract

A refrigerant flow divider in which corrosion resistance of an aluminum or aluminum-alloy main body is evenly improved. A refrigerant flow divider (10) comprises a first refrigerant tube (20), a plurality of second refrigerant tubes (30), a main body (40), a first plate (50), and a second plate (60). The main body (40) is made of aluminum or an aluminum alloy. The main body (40), in which the flowof a refrigerant is divided from the first refrigerant tube (20) to the plurality of second refrigerant tubes (30), has a first surface (41) to which the first refrigerant tube (20) is connected, anda second surface (42) to which the plurality of second refrigerant tubes (30) are connected. The first plate (50) has a first sacrificial anode layer (54) that is joined to the first surface (41) andfaces the main body (40) on the external surface that is exposed to the air. The second plate (60) has a second sacrificial anode layer (64) that is joined to the second surface (42) and faces the main body (40) on the outer surface that is exposed to the air.

Description

technical field [0001] A refrigerant flow divider comprising a main body made of aluminum or aluminum alloy and an air conditioner comprising the refrigerant flow divider. Background technique [0002] Among conventional refrigerant flow dividers, there is an aluminum refrigerant flow divider as described in Patent Document 1 (International Publication No. 2016 / 002280), for example. In the aluminum refrigerant distributor described in Patent Document 1, the corrosion resistance of the parts made of aluminum affects the service life of the refrigerant distributor. For example, when aluminum or an aluminum alloy is used for a main body that divides refrigerant, the main body may be damaged by corrosion of the aluminum or aluminum alloy, resulting in leakage of the refrigerant. Contents of the invention [0003] The technical problem to be solved by the invention [0004] Therefore, as a method of improving the corrosion resistance of the main body, for example, a process o...
