Description

A gas-liquid separation structure for a gas-liquid separator

Technical Field

The utility model relates to the technical field of automobile air conditioners, in particular to a gas-liquid separation structure used for a gas-liquid separator.

Background Art

The gas-liquid separator is an important component of the automotive air-conditioning system and is generally installed between the evaporator outlet and the compressor intake. Its main functions are: (1) to store the liquid refrigerant in the air-conditioning system and adjust the system refrigerant circulation volume under different working conditions; (2) to separate the gas-liquid mixed refrigerant into gas and liquid to prevent the liquid refrigerant from flowing into the compressor and causing "liquid hammer" in the compressor, thereby ensuring the reliability of the compressor operation.

Existing gas-liquid separators all have a gas-liquid separation chamber (or gas-liquid separation channel), which achieves gas-liquid separation through a complex curved inner wall. Such a complex gas-liquid separation chamber is difficult to manufacture, requiring a large space to arrange a sufficiently long flow path, which greatly increases the volume and cost of the gas-liquid separator. In addition, there are many chambers inside the separator shell. Since most of the separator shells are currently formed in one piece, the chamber processing is relatively difficult.

DETAILED DESCRIPTION

The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.

An embodiment of the utility model relates to a gas-liquid separation structure for a gas-liquid separator, as shown in Figures 1-5, comprising a separator shell 1, wherein a gas-liquid separation chamber is arranged inside the separator shell 1, an inlet 1 2 and an inlet 2 3 are provided on one side of the gas-liquid separation chamber, the inlet 1 2 and the inlet 2 3 are both connected to the side wall of the separator shell 1, an outlet 4 is provided on the other side of the gas-liquid separation chamber, the outlet 4 is connected to the channel inside the separator shell 1, the middle part of the gas-liquid separation chamber is divided into chamber 1 10 and chamber 2 11 by a baffle plate 5, an air port 6 connecting chamber 10 and chamber 2 11 is provided on the baffle plate 5, the inlet 1 2 and the inlet 2 3 are provided on one side of the chamber 10, the outlet 4 is provided on the side of the chamber 2 11, an arc-shaped spoiler 1 7 is provided on the baffle plate 5 on the side of the air port 6, and the arc-shaped spoiler 1 7 is located in the chamber 10.

As shown in Figure 2, the low-temperature and low-pressure liquid refrigerant and the medium-temperature and medium-pressure liquid refrigerant are mixed and enter through inlet 1 2, and the low-temperature and low-pressure gas-liquid two-phase refrigerant from the evaporator outlet enters through inlet 2 3, and then is mixed in the gas-liquid separation chamber of the gas-liquid separator 1, thereby increasing the superheat of the refrigerant at the outlet of the gas-liquid separator 1.

The arc-shaped spoiler plate 7 on the baffle plate 5 can form a disturbing and guiding effect on the gas-liquid two-phase mixed refrigerant airflow. In the process of the main fluid turning, the fine droplets in the airflow will sink and separate from the gas. At the same time, the main fluid and the part of the airflow that bypasses the arc-shaped spoiler plate 7 impact each other, achieving the effect of airflow disturbance. The droplets in the airflow lose kinetic energy and turn after being thrown and collided by the high-speed airflow, which can greatly improve the separation capacity of the gas-liquid separator 1.

As a preferred solution for the outlet 4 and the air port 6, the outlet 4 and the air port 6 are staggered, which can effectively extend the flow path of the gas-liquid two-phase refrigerant.

In order to better improve the separation ability of the gas-liquid separator 1, an arc-shaped spoiler plate 2 8 is provided on the side of the chamber 2 11 located at the outlet 4 near the gas port 6. The arc-shaped spoiler plate 2 8 also has the function of disturbing and guiding the gas-liquid two-phase mixed refrigerant airflow. A guide plate 9 is provided on the other side of the gas port 6. The guide plate 9 is used to guide the airflow out. The arc-shaped spoiler plate 1 7 plays the first disturbing and guiding role, and the arc-shaped spoiler plate 2 8 plays the second disturbing and guiding role, which can greatly improve the separation efficiency.

As an illustration of the arc-shaped spoiler 1 7 and the arc-shaped spoiler 2 8, the opening direction of the arc-shaped spoiler 1 7 is opposite to the opening direction of the arc-shaped spoiler 2 8, as shown in FIG. 1 . Such an arrangement can maximize the effects of the two arc-shaped spoilers and greatly improve the separation effect.

As an illustration of the separator shell 1, the separator shell 1 is composed of a shell 13, a partition 14, a shell 15 and a partition 16 connected in sequence. There are multiple cavities inside the separator shell 1. The separator shell 1 is designed as a multi-section splicing structure, which is conducive to reducing the processing difficulty of the entire separator shell 1. Both sides of the cavity on the upper part of the shell 15 are through, and the cavity is blocked by the partition 14 and the partition 16 to form a gas-liquid separation chamber. The outlet 4 and the arc spoiler 2 8 are both arranged on the partition 14, and the inlet 1 2 and the inlet 2 3 are both arranged on the outside of the partition 2 16; the outside of the partition 2 16 is also provided with a liquid refrigerant outlet 18 and a gas-liquid separator outlet 17; a desiccant assembly 19 is installed in the lower part of the separator shell 1, and the desiccant assembly 19 is filled with a molecular sieve that can absorb moisture in the refrigerant.

As a limiting structure of the baffle plate 5, a positioning notch 25 is provided on both sides of the middle of the gas-liquid separation chamber, and the left and right sides of the baffle plate 5 are provided with side fitting parts 20 that are tightly fitted with the inner wall of the gas-liquid separation chamber. One end of the side fitting part 20 is interlocked with the positioning notch 25 to limit the baffle plate 5 and ensure the position accuracy of the baffle plate 5.

As a setting scheme for the liquid passage opening 12, a through opening 24 is provided at the bottom of the gas-liquid separation chamber, and an upper fitting portion 22 and a lower fitting portion 21 which are tightly fitted to the inner wall of the gas-liquid separation chamber are respectively provided on the upper and lower sides of the baffle plate 5, and the lower fitting portion 21 is provided on the through opening 24, and the lower fitting portion 21 is located below the gas passage opening 6 and below the outlet 4, and a liquid passage notch 23 is provided. The lower fitting portion 21 blocks most of the through opening 24, leaving only the position of the liquid passage notch 23, and the liquid passage notch 23 and the edge of the through opening 24 form the liquid passage opening 12; because liquid droplets are easily formed at the positions near the gas passage opening 6 and the outlet 4, the formed liquid droplets can continuously accumulate in the cavity at the lower part of the separator shell 1 along the liquid passage opening 12, and then be stored.

As an installation description of the baffle 5, as shown in FIG1, during installation, the baffle 5 is loaded from the rear of the upper cavity of the second shell 15, and the side fitting parts 20 on both sides are tightly fitted with the inner walls on both sides of the gas-liquid separation chamber, and one end of the side fitting part 20 is interlocked with the positioning notch 25 to achieve the limit of the front side of the baffle 5, and then the baffle 1 14 is welded to the rear side of the second shell 15, and the end face of the baffle 1 14 supports the upper fitting part 22 and the lower fitting part 21 to achieve the entire fixed installation of the baffle 5. Of course, this is only one way of fixing, and the baffle 5 can also be directly welded and fixed to the inner wall of the gas-liquid separation chamber after one end of the side fitting part 20 is interlocked with the positioning notch 25 to achieve the limit of the front side of the baffle 5.
