Description

Novel gas-liquid separator

Technical Field

The utility model relates to an air conditioner component, in particular to an improved gas-liquid separator, and specifically relates to a novel gas-liquid separator.

Background

The gas-liquid separator is a common part of an air conditioner outdoor unit, and generally comprises a cylinder, an air inlet pipe, an air outlet pipe and other structures, and a pressure equalizing hole is formed in the air outlet pipe, so that when the compressor is stopped under the condition that the accumulation amount of the liquid refrigerant in the gas-liquid separator is fixed, the pressure in the cylinder can be balanced, and the liquid refrigerant is ensured not to flow into the compressor. At present, an air inlet pipe and an air outlet pipe of a common gas-liquid separator are generally arranged at the top of an air separator, and a pressure equalizing hole is arranged on the air outlet pipe. However, as products are more and more miniaturized and cost-reduced, the structure of the conventional gas-liquid separator cannot meet the requirements, and needs to be improved urgently.

Detailed Description

The utility model is further described below with reference to the figures and examples.

As shown in fig. 1.

A novel gas-liquid separator comprises a cylinder body 4, an air inlet pipe 4, an air outlet pipe and a pressure equalizing pipe 2.

The cylinder 4 is a closed cylinder, may be a cylindrical cylinder, or may have another shape.

The air inlet pipe 1 is straight and is arranged at the top end of the cylinder 4 in a penetrating manner, and the outlet end of the air inlet pipe is positioned in the cylinder 4 and close to the top of the cylinder 4.

The air outlet pipe comprises an inner side pipe 3 and an outer side pipe 6, and is penetratingly arranged at the bottom of the cylinder body 4. The inner pipe 3 is positioned in the cylinder 4, and the outer pipe 6 is positioned outside the cylinder 4 to form a U-shaped structure. Other shapes are also possible. The inner tube 3 is a straight tube, and the end part of the straight tube is close to the top of the cylinder 4. The length of the inner pipe 3 determines the effective volume of the gas-liquid separator, and therefore, in principle, the larger the length, the larger the effective volume. However, the end of the inner pipe 3 cannot be pushed to the top of the cylinder 4, so as not to affect the normal operation of the gas-liquid separator. The outer pipe 6 can be in a folded pipe shape so as to better meet the assembly requirement of the unit. Preferably, the outer pipe 6 can be connected with the side wall of the cylinder 4 through the fixing plate 5, so that the normal operation of the unit is prevented from being influenced by shaking.

The pressure equalizing pipe 2 is positioned outside the barrel 4, the upper end of the pressure equalizing pipe is connected and communicated with the top end of the barrel 4, and the lower end of the pressure equalizing pipe is communicated with the outer side pipe 6, so that the pressure equalizing effect is realized. Preferably, the height of the end of the inner pipe 3 is larger than that of the end of the outer pipe 6, so that the pressure equalizing effect is ensured.

The air outlet pipe is arranged at the bottom of the cylinder in a penetrating manner, and the height of the inner side pipe is reasonably arranged, so that the requirement of gas-liquid separation of the refrigerant is effectively met under the condition that the internal structural space is limited. Simultaneously, through setting up the equalizer tube, be linked together barrel top and outside pipe, effectively solved its inside pressure balance's problem. Moreover, the utility model has simple structure and convenient installation, can fully meet the market demand and is worth popularizing.

The parts not involved in the present invention are the same as or can be implemented using the prior art.
