Embodiment 1

[0029] The fluid enters the separator from the two-phase inlet (1) on the upper layer, and enters the grooved body (4) in the middle through the guidance of the upper drainage partition (2). In the groove, the liquid flows down along the groove, while the gas flows to The center escapes and then flows upward, the lower partition (5) blocks the gas flow path, the separated liquid enters the liquid collection chamber (6), flows out from the lower liquid phase outlet (8), and the gas flows from the gas phase outlet (7) flow out. Wherein, the tank body (4) is the most important part of this gas-liquid separator, as shown in Figure 4 and Figure 4.1 As shown, the appearance of the tank body is cylindrical, and it is specifically bent from a straight plate, and is installed upright in the tank body.

[0030] Its working principle is: after the fluid reaches the tank body, it all flows into the groove 4-1, the liquid phase continues to flow downward due to inertial force and gravity...

Embodiment 2

[0038] Another embodiment of the present invention is further described in detail with reference to FIG. 8 .

[0039] Its embodiment is: the above-mentioned other structures remain unchanged, the difference is that in this embodiment, window-type fins are inserted inside the main body groove, specifically, the tank body of the gas-liquid separation unit is composed of the main body groove 8-1, the fin 8 -2, arranged in a triangular shape, consisting of a separation space 8-3 inside the fin, a separation space 8-4 in the fin part, and a fin window 8-5.

[0040] Of course, the main groove 8-1 may also be provided with auxiliary grooves and corresponding position and direction relationships.

[0041]Its working principle is: from the perspective of each groove unit, after the two-phase fluid enters the groove body, part of the fluid is separated in the space 8-3 inside the fins, and the other part realizes gas-liquid in the triangular space formed by the fins. Separation, in add...

Abstract

The invention relates to a gas-liquid separator with a surface tension type groove body, aims to overcome defects in the prior art, and provides a novel surface tension type gas-liquid separator groove body. One technical scheme is that micro runners are etched in assigned positions of a copper / aluminium panel and are adopted as secondary grooves of gas-liquid two-phase separation, then, the panel is bent into the cylindrical groove body, and a main groove is acquired. The other technical scheme is that firstly, the panel is bent into the cylindrical groove body, then, fins are pressed and windows are formed according to the size of the corresponding grooves, finally, the fins are inserted into the grooves, and welding is carried out. The two schemes are aimed at increasing the effective separation area, fully utilizing the surface tension effect, improving separation efficiency, carrying out gas-liquid separation more effectively, further miniaturizing the separator, decreasing the device size, further achieving high performance, and reducing cost.

Description

technical field [0001] The invention relates to a gas-liquid two-phase refrigerant separation device suitable for refrigeration cycles, in particular, a gas-liquid separator with higher performance, smaller size and more reliability is sought in the field of refrigeration. Background technique [0002] In a general refrigeration system, it includes an evaporator, a compressor, a condenser and a throttling device. After the refrigerant exchanges heat with the external environment through the evaporator, it needs to return to the inlet of the compressor for compression. If the refrigerant entering the compressor is mixed with liquid refrigerant, it will be harmful to the compressor. Therefore, it is necessary to separate the gas and liquid of the refrigerant entering the inlet of the compressor. In addition, most refrigerants are in a gas-liquid two-phase state before entering the evaporator. If the gas-liquid phases of the refrigerant are separated after the expansion valve...
