Automobile all-aluminum air heater and assembling method thereof

Abstract

The invention relates to an automobile all-aluminum air heater and an assembling method thereof. The air heater comprises a water chamber, a bent pipe and a core body, the water chamber is buckled on the core body, the bent pipe is installed on the water chamber, the core body comprises a heat dissipation pipe and a main piece, the heat dissipation pipe is connected with the main piece, the main piece is installed on the water chamber, and flaring openings are formed in the two ends of the heat dissipation pipe. The assembling method of the air heater comprises the steps that the main pieces, side plates, the heat dissipation pipes and heat dissipation belts are assembled and then bundled and connected together to form the core body; the water chamber with an inserted sheet is buckled and pressed on the core body; the core body and the water chamber are connected and fixed together through brazing; the bent pipe is welded; and a sponge strip is pasted, and assembling of the air heater is completed. Compared with the prior art, the method has the advantages of high brazing qualification rate, low rework rate and the like.

Description

Technical field [0001] Technical Field The present invention relates to a car heater, and more particularly relates to a heater core of an automobile and a method of assembling aluminum. Background technique [0002] With the improvement of people's living standards, more and more demands on the car, the car air-conditioning requirements are also increasing. Car heater car heater system as an important key components required for its manufacturing techniques have become more sophisticated. [0003] Currently, the prior art heater structure as figure 1 with figure 2 , The following disadvantages: [0004] 1, after the welding heat pipe leakage, was affecting yield of the solder; [0005] 2, after welding the product diagonal size is too large, appearance of the product and affect the installation; [0006] 3, scrap rate was seven thousandths, resulting in unnecessary material loss; [0007] 4, rework rate thousandths, resulting in unnecessary human losses. Inventive content [00...

AI Technical Summary

Problems solved by technology

[0004] 1. After welding, there are many leakages of heat pipes, which affects the qualified rate of brazing;

[0005] 2. The diagonal size of the product after welding is too large, which affects the installation and product appearance;

[0006] 3. The scrap rate reaches 7 / 1000, causing unnecessary material loss;

[0007] 4. The rework rate reaches 10 per thousand, causing unnecessary manpower loss
