Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of liquid accumulator, concretely relates to a liquid accumulator for carbon dioxide refrigerant. BACKGROUND

[0002] The carbon dioxide refrigerant liquid accumulator is an important component in the carbon dioxide refrigeration system, and mainly serves to store liquid carbon dioxide refrigerant and supply the refrigeration system when needed.

[0003] Chinese patent publication No. CN221403554U discloses a liquid accumulator for carbon dioxide refrigerant, which comprises a liquid storage tank, and a feed pipe is installed on one side of the top of the liquid storage tank. By setting the flow guide assembly, the flow guide assembly is located on one side of the bottom of the feed pipe. Then, after the external liquid carbon dioxide enters the liquid storage tank through the feed pipe, the liquid carbon dioxide continuously impacts the rotating fan during the falling process, so that the rotating fan rotates towards the adjacent side wall in the liquid storage tank through the guide sealing shaft. The rotation of the rotating fan can guide the entering liquid carbon dioxide to the inner wall of the liquid storage tank, so that it flows downward along the inner wall, avoiding the vertical falling impact on the internally stored liquid carbon dioxide, preventing the liquid carbon dioxide from producing large shaking in the liquid storage tank, thereby avoiding the increase in the number of carbon dioxide vapor molecules and the increase in activity, reducing the molecular impact force and the internal pressure of the liquid storage tank, and preventing potential safety hazards.

[0004] In the prior art disclosed above, the liquid storage tank can be used to store liquid carbon dioxide. During the falling process of the liquid carbon dioxide, the liquid carbon dioxide impacts the rotating fan and is guided to flow downward along the inner wall of the liquid storage tank, preventing the liquid carbon dioxide from producing large shaking in the liquid storage tank. However, when the liquid carbon dioxide impacts the rotating fan, it is easy to splash in all directions, and not all of the liquid carbon dioxide can be guided to flow along the inner wall of the liquid storage tank. The splashed liquid carbon dioxide still vertically falls and impacts the internally stored liquid carbon dioxide, thereby reducing the use effect. In addition, the support angle of the liquid storage tank is fixed, and it is inconvenient to adjust the support angle of the liquid storage tank according to the inclination of the installation ground.
