Problems solved by technology

The existing production process of the condenser adopts spraying flux on the formed condenser and then welding. Using this process, the external solder joints of the finished condenser are not beautiful, and there are crystal residues, and since the flux is sprayed on the open Carried out in the environment, easy to pollute the environment

Embodiment

[0022] Embodiment: a kind of such as figure 1 The production process of the coreless header of the automobile air-conditioning condenser shown includes the following steps:

[0023] Step 1: Clean the pure aluminum plate as the substrate with pure water at a temperature of 75-85°C, then blow dry at a drying temperature of 95-100°C, and then cool it to room temperature naturally, and use an aliphatic hydrocarbon solvent on the surface of the dried substrate Wash 2-3 times, rinse again with pure water at a temperature of 50°C, and finally blow dry with a fan for use;

[0024] Step 2: Take two substrates after step 1, sandwich a composite plate between the two substrates to form a three-layer composite structure, wherein the composite plate is made of aluminum powder and flux, and the aluminum powder and flux The component ratio is 7:3;

[0025] Step 3: Pass the three-layer composite structure obtained in Step 2 through a plate rolling machine to obtain an oblate condenser corel...

Abstract

The invention relates to the field of automobile air conditioner manufacturing, in particular to a production process of an automobile air conditioner condenser coreless flow collecting pipe. According to the production process, the method of enabling a composite board to be clamped in the middle of a substrate is adopted, the composite board is composed of aluminum powder and a brazing flux, in the welding process, due to the "capillary action", the brazing flux permeates into the substrate from a weld joint, the effects that the oxidation is reduced in the heating process is achieved, the anti-corrosion and anti-oxidation effects are achieved, due to the fact that the disclosed production process is adopted, the brazing flux does not need to be sprayed on the condenser coreless flow collecting pipe, in the brazing flux spraying process, manpower is used, the waste of the brazing flux can not be avoided, therefore, due to the fact that the spraying step is omitted, the labor cost andthe brazing flux consumption are saved, moreover, the workshop environment is not polluted, and the environment-friendly effect is achieved.

Description

technical field [0001] The invention relates to the field of automobile air conditioner manufacturing, in particular to a production process for a coreless collector of an automobile air conditioner condenser. Background technique [0002] Automobile air conditioners are used to adjust and control the temperature, humidity, air cleanliness and air flow in the car compartment to the best state, provide passengers with a comfortable riding environment, and reduce travel fatigue; create good working conditions for drivers and ensure Ventilation device that plays an important role in safe driving. Generally include refrigeration equipment, heating equipment and ventilation equipment. This combination device makes full use of the limited space inside the car, has a simple structure and is easy to operate. It is a modern car air-conditioning system popular in the world. [0003] The automotive air-conditioning refrigeration system consists of a compressor, a condenser, a liquid ...
