Problems solved by technology
However, during the installation process of this all-aluminum heat exchanger, it is inevitable to come into contact with iron-containing screws and sheet metal parts. Since the chemical properties of aluminum are more active than iron, a galvanic battery will be formed when it comes into contact with iron, thereby accelerating the heat loss of aluminum. The chemical reaction of the aluminum causes faster aging of the aluminum, which ultimately affects the life of the aluminum heat exchanger

The invention discloses a heat exchanger fixing structure. The heat exchanger fixing structure comprises an aluminum mounting plate which is fixedly connected with a heat exchanger, an upper plastic buckling plate and a lower plastic buckling plate, wherein at least one boss-shaped screw base and at least two buckles are arranged on the upper plastic buckling plate; a mounting plate screw base passing hole which is matched with the screw base is formed in the aluminum mounting plate; a lower buckling plate screw base passing hole which is matched with the screw base and buckling holes which correspond to the buckles are formed in the lower plastic buckling plate; and the screw base penetrates through the mounting plate screw base passing hole and the lower buckling plate screw base passing hole in sequence, and the buckles are buckled with the buckling holes, so that the aluminum mounting plate is clamped and fixed by the upper plastic buckling plate and the lower plastic buckling plate. According to the heat exchanger fixing structure, the aluminum mounting plate is clamped and fixed by the upper plastic buckling plate and the lower plastic buckling plate, and metal parts are completely isolated from the aluminum mounting plate and an aluminum heat exchanger to protect the aluminum heat exchanger and the aluminum mounting plate, so that the service life of the aluminum heat exchanger can be prolonged, and furthermore, the reliability and the safety of an air conditioner are improved.
Description
Technical field [0001] The invention relates to the technical field of air conditioners, in particular to a heat exchanger fixing structure and a heat exchanger. Background technique [0002] Compared with copper, the content of aluminum in nature is greater, and the content of aluminum in the earth's crust is about 8%. Therefore, the source of aluminum is more abundant than copper and the price is cheaper. At the same time, aluminum also has good thermal conductivity, so in recent years many manufacturers have begun to use aluminum instead of copper to produce heat exchangers. The current aluminum heat exchangers mainly include parallel flow heat exchangers and aluminum round tube heat exchangers. However, in the installation process of this kind of all-aluminum heat exchanger, it is inevitable to contact with iron-containing screws and sheet metal parts. Because the chemical properties of aluminum are more active than iron, galvanic cells will be formed when it comes into cont...
