Brazing Evaporator Coil

Evaporator Coil Brazing Machine Description

Evaporator Coil is a very important component of the air conditioning system. Evaporator Coil Brazing needs to be firm, leak-proof, and durable. Because of the large number of solder joints, manual soldering will inevitably make mistakes. Evaporator Coil Brazing Machine increases the brazing speed and improves the brazing quality through automation.

The Condenser and Evaporator are functionally different, but the manufacturing process is similar.

Evaporator Coil Brazing Machine Buying Guide

Air-conditioners have an important part named evaporating coil. The brazing process ensures the strong joint so that nothing is leaked to reduce the working of air-conditioners.

When learning about brazing evaporating coil, it is essential to know that air-conditioners also take air present in your room and return it after cooling it off.

1.     What Is Evaporating Coil? 

Evaporating coil is used in air-conditioners. Its function is to absorb and throw the heat from the inside out. 

The evaporating coil is in an air handler or it is sometimes attached to a heater.Role of Evaporator Coil in an Air-conditioner?

The evaporator coil function is to take the hot air of the room where the air-conditioner is working and then add the air to the refrigerant. 

Return ducts gather the indoor hot air from the room, and when they are passed near the copper tubes with refrigerant, the hot air is cooled and returned to the room.

2.     Why Is Brazing Evaporator Coil Important?

Brazing is a method of joining metals, and the evaporator coil has hot air which needs to be cooled down. 

To avoid any leakage, the evaporator coil is brazed so that the joint is solid and secure, and there are no chances of leakage to enhance the overall quality of the air-conditioner.

3.     Why Is Brazing Machine Better than Manual Brazing?

Manual brazing is done one by one by hand, and a brazing machine is used for brazing the evaporator coil because of several reasons. 

  • The brazing machine is more precise, and there are fewer chances of leakage due to improper brazing.
  • Brazing machines are better when working on a large scale because they are fast and can braze more evaporator coils in less time, saving time and energy.
  • Using an automatic brazing machine can reduce the number of workers you need to braze the coils manually; therefore, it saves human resources.

4.     What are the Different Categories of Evaporator Coils?

You cannot deny the use of evaporator coils in air-conditioners, and certain types make a difference in the cooling outcome of an air-conditioner.

Brazing Evaporating Coil

A-Shaped Evaporator Coils

Structure-wise, this is the most useful and easy-to-understand type of evaporator coil. As the  

Outer slanted tubes and inner tubes that are filled with refrigerant. When hot air passes through the outer A-shaped slants, the refrigerant cools It down, and then it is reversed back to the room.

Many brands of high quality use this type of evaporator coil. The brands that use this type of evaporator coils are Lennox, Goodman, and Trane.

N-Coil or Z-Coil / Zigzag Evaporator Coils

These evaporator coils are more efficient, and many industries use them. They can be installed horizontally or vertically. 

The zigzag evaporator coils have a third leg of fins that make it take more hot air and output cold air, making it more valuable than other evaporator coils.

Slab Evaporator Coils

These evaporator coils are used in horizontal air-flow handles. They are less capable in their function, but they can be easily cleaned and use less space.

5.     What Are the Common Products of Brazing Evaporator Coil?

The most common products obtained from the brazing of evaporator coils are:

  • Brazing aluminum evaporator
  • Brazing N or Z-shaped evaporator coils
  • Evaporator in refrigerator
  • Aluma fin7 evaporator coil

6.     What Are the Common Steps in the Brazing Process of Automatic Evaporator Coil Brazing?

Some steps are followed in the brazing process, either manual or automatic.

  • First of all, the joints that we need to braze are cleaned
  • Then joints are held together, and flux is applied, which helps in solid brazing
  • Then the joints are placed how we want to join them 
  • This step is about the addition of filling metal. Filling metals are alloys of metals that quickly melt when heat is applied to fill the gaps between the joint and have a leak-proof and strong joint.
  • The last step is the cleaning process. In this step, the joint is cleaned and polished if needed. You can also check if the joint is leak-proof to feel sure about the joint.

7.     Why Cleaning the Evaporator Coil Is Important?

The evaporator coil is essential in cooling the air by the air-conditioner. If kept in bad condition, the corrosion can damage it.

The air-conditioner may use more energy, which can cause overheating if the evaporator coil is not cleaned or damaged.

8.     What Metals Are Used in Evaporating Coils?

Evaporating coils are made of metals that are quickly cooled, and these metals are light and, therefore, readily brazed to get the best quality brazing evaporator coils. Metals like aluminum, copper, and steel are used in evaporator coils.
