In the eyes of the newcomers, the structure of the RDA is similar, and nothing more than the base and an outer warehouse. In fact, the base of the RDA can also be divided into a variety of structures, which can be divided into common “double columns” and “three columns” according to the number of electrode columns. In particular, the more popular “U-shaped double-column 4-hole” structure this year is widely used in RDA and RDTA.
So what are the differences between the different structures and what are the advantages? Today, I will give you a look at the common drip base structure so that novices can find the type that suits them best when they are selected.
RDA base structure classification
According to the number of electrode columns, the base of the RDA can be divided into three common types: double column and triple column.
As the name suggests, the double column is the structure with two electrode columns on the base, one positive and one negative. A three-column refers to a structure with three electrode columns, usually two negative columns and one positive column.
Double column double hole
The double-column double-hole structure refers to a structure with two positive and one negative electrode columns, each of which has a threading hole.
The advantage of this structure is that it is convenient to install the coil, and even if the wire is not intentionally adjusted, a relatively standard double-shot center coil can be produced.
The disadvantage is that the two hairs share two threaded holes, which is not very convenient when trimming the legs. If the shape of the wire is not directly adjusted, the outer side of the coil is easily deformed. Due to the small number of threading holes, it is not suitable for making multiple coils (multiple hair), a typical “double hair” structure. Moreover, when fixing the coil, it is necessary to use two winding rods at the same time to insert the coil to assist the fixing to prevent the coil from being deformed.
Strategy: The double-column double-hole structure has the same height of the threaded hole, so it is necessary to make more than 90 degrees and then adjust the shape of the wire to make a relatively standard center coil.
Three-Column Structure
The common three-column structure is mostly three-column three-hole, two negative-electrode columns are located on both sides of the atomizer, and one positive-positive column in the middle, and one electrode hole is arranged on each electrode column.
The structure of the three-column and three-hole structure is that the positive electrode column is shared when the double-shot is made, and the four-hair electrode can also be made. However, the middle positive electrode column has to pass through the four-wire thread through the wire hole, and it is troublesome to fix and trim.
To make a center coil when making a double shot, it is necessary to adjust the stitch of the coil, which is troublesome for the novice. If the wire is not adjusted, the center coil can be made by directly pushing the coil with the tool and pushing the coil in the middle. However, the coil may be deformed or the edge coils may overlap to affect the heat generation.
Comments: The three-column and three-hole structure is the most common in the RDA, but it is more troublesome when installing the coil, and the production of the middle heating wire also needs to adjust the stitch of the coil. If the novice uses it, there will be certain difficulty. It takes a lot of practice to get started.
Conclusion
Through the above content, we have shared several common structures of the electrode column of the RDA. The novice can refer to it when purchasing. The author’s personal opinion is that you can start with a double-column four-hole or choose a four-column four-hole structure, which is easier for novices. But there is no absolute thing, as long as it is what you like, then it is for you.
Every different structure requires the user to be familiar with the structure in order to make a suitable coil for matching, which is also the charm of vape.
