Description

A single-sided inflation evaporator

Technical field:

The utility model relates to a single-sided inflation evaporator, which is especially suitable for the field of refrigeration of household appliances.

Background technique:

In the modern refrigeration industry, the blown evaporator is a common structure. It has the advantages of high heat transfer efficiency, fast refrigeration speed, and beautiful appearance, and is suitable for direct cooling refrigeration equipment. The pipeline of the blown evaporator is divided into two types: double-sided outer drum and single-sided outer drum. The inner surface of the plate evaporator with double-sided outer drum is uneven, and it is easy to wear and tear during use. The traditional single-sided inflation evaporator is to print the pipeline made of graphite on the aluminum plate through the screen after cutting the aluminum plate, and then combine the two plates tightly together by hot rolling. If there is no sticking together, the pipeline is swelled by gas, and then the processing is completed through trimming, punching, powder spraying and other processes. The process flow is blanking - printing - hot rolling - bulging - scribing , Cutting - punching - powder spraying and so on.

Invention content:

The task of the utility model is to propose a single-sided blowing evaporator with a single-sided outer drum, reduced technology and simple processing.

The task of this utility model is accomplished in this way, a single-sided inflation evaporator, characterized in that: the bulging pipeline with convex and concave surfaces on the surface of the aluminum plate is formed by one-time punching, and the composite substrate and the aluminum plate are bonded. One side is coated with a layer of flux, and after the two are fixed, they are formed into a single-sided inflation evaporator by brazing and sintering. The composite substrate is a non-bulging aluminum plate, and the composite substrate is single-sided composite/double-sided composite. The combined surface of the aluminum plate has a composite surface marking line.

The utility model has the following effects:

1. One-time stamping and forming, the internal volume is guaranteed to be reliable;

2. Once processed and formed, the flatness is guaranteed to be reliable;

3. The processing procedure is reduced and the process is simplified;

4. The sintering process is mature and the product quality is guaranteed;

5. The processing is easier, and the cost of raw materials and processing input is lower.

detailed description:

The single-sided evaporator of this technical solution adopts a structure formed by sintering; one aluminum plate of the single-sided inflation evaporator is directly stamped, and the other aluminum plate is fixed in a brazing furnace for sintering; One-time stamping forming; non-bulging plate adopts composite aluminum plate; composite aluminum plate can be single-sided composite aluminum plate or double-sided composite aluminum plate. The embodiment is described in detail in conjunction with the above drawings. As shown in Figures 1 and 2, the bulging pipeline with convex surface 2 and concave surface 3 on the surface of the aluminum plate 1 is formed by one stamping, and the composite substrate 5 is a non-bulging aluminum plate. (As shown in Figures 3 and 4), the side of the composite substrate bonded to the aluminum plate 1 is coated with a layer of flux 4 and after the two are fixed, they are sintered in a brazing furnace to form a single-sided inflation evaporator (as shown in Figure 5 and Figure 6),. The composite substrate is single-sided composite/double-sided composite, and the side combined with the aluminum plate 1 has a composite surface marking line, which is used to distinguish whether there is a composite layer, which is convenient for assembly.

Through such changes, we not only obtained a more stable and reliable internal volume, better flatness, but also fewer processes and simpler processing processes, and the sintering process is very mature, and the sintering quality is very high, which can fully meet the needs of blown products. It meets the requirements of pipeline pressure resistance and leakage prevention, and reduces the input of scraps of raw materials and sponges and graphite for bulging, which is more economical and economical. Compared with the traditional single-sided inflation evaporator, it has obvious advantages.
