Embodiment Construction
[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention, the following combined Figure 1 ~ 4 And examples are described in further detail. It is to be understood that the specific embodiments described herein are intended to explain the present invention and is not intended to limit the invention.
[0033] It should be noted that when the element is referred to as "fixed to" or "set to" another element, it can be directly on the other element or indirectly on the other element. When a component is called "connected to" another element, it can be directly connected to another element or indirectly connected to the other element.
[0034]It is to be understood that the term "length", "width", "upper", "lower", "front", "post", "right", "vertical", "level", "top" The orientation or positional relationship of "bottom", "inside", "outside", etc. is based on the orientation or positional relationship shown in the d...

The invention belongs to the technical field of refrigeration equipment, and particularly relates to a scroll compressor, refrigeration equipment and a vehicle. The scroll compressor comprises a machine shell internally provided with an oil separation structure and a throttling connection structure, a compression cavity, an oil return channel, a first oil storage cavity and a second oil storage cavity are further formed in the machine shell, the first oil storage cavity is communicated with an oil outlet of the oil separation structure, and the second oil storage cavity is communicated with the first oil storage cavity through the throttling connection structure. The second oil storage cavity is provided with an oil outlet end communicated with the oil return channel and an air storage end communicated with the compression cavity. Refrigeration oil separated by the oil separation structure enters the second oil storage cavity after being subjected to pressure reduction treatment through the first oil storage cavity and the throttling connection structure, the temperature and pressure of the refrigeration oil are reduced, refrigerants dissolved in the refrigeration oil are separated out and discharged to the compression cavity, and therefore when the refrigeration oil flows into the oil return channel from the second oil storage cavity, the refrigerants and heat carried by the refrigeration oil are reduced, and the refrigeration efficiency is improved. Therefore, reduction of volume efficiency and refrigerating capacity of the scroll compressor can be avoided, and guarantee is provided for efficient compression.
Description
Technical field [0001] The present invention belongs to the technical field of refrigeration equipment, and more specifically, it is to relate to a scroll compressor, a refrigeration device, and a vehicle. Background technique [0002] The vortex compressor is a highly efficient and lowest noise, a stable volumetric compressor, which is widely used as a third-generation car compressor in the automotive air conditioning system. In recent years, with the development of new energy vehicles, the car is Air conditioning scroll compressor noise, vibration and durability, etc. are further improved. Among them, in the process of use, the car scroll compressor needs to provide frozen oil to the friction pair of friction in the scroll compressor, to reduce the noise generated during friction, generally, in the existing scroll compressor In the middle, since the refrigeration oil is small, it is often used to provide a frozen oil separated by the high-voltage side to the oil-frozen oil to t...
