Cooling structure of oilless scroll compressor

Abstract

The invention discloses a cooling structure of an oilless scroll compressor. The end surfaces of backs of scroll teeth of a fixed scroll and an orbiting scroll are provided with heat pipes and heat radiating fins, so that the heat pipes are fixedly arranged on the end surfaces of the backs of the scroll teeth of the fixed scroll and the orbiting scroll; heat generated by the fixed scroll and the orbiting scroll in a working process of the compressor is conducted by virtue of the heat pipes; the centralized conduction of the heat of the fixed scroll and the orbiting scroll is realized by virtueof the heat radiating fins arranged on the heat pipes in parallel; the heat generated in a compression chamber of the scroll compressor is rapidly delivered to an air flow passage by virtue of the characteristic of phase change heat transfer of the heat pipes; and then, the heat is taken away from a compressor set by virtue of strong wind generated by an axial flow fan, and the heat inside the compressor can be rapidly radiated into the environment, so that the high-efficiency heat exchange demand is met, and the temperature of the whole scroll compressor in working is rapidly and continuously reduced. The device is simple in structure, convenient to implement and simple in maintenance.

Description

technical field [0001] The invention belongs to the technical field of compressor cooling, and in particular relates to a cooling structure of an oil-free scroll compressor. Background technique [0002] The oil-free scroll compressor has the advantages of small size, high efficiency, low noise, long service life, simple structure, etc. It is a compressor type that has developed rapidly in recent years. Oil-free compressors are widely used in the food industry, medical equipment, new energy fields, automotive braking systems, vacuum fields, etc. However, due to its own structural characteristics, there are a large number of friction pairs that generate frictional heat during operation and cannot be quickly and directly discharged, resulting in an increase in the temperature of the compressor body and the discharge temperature. At present, almost all scroll oil-free compressors use a single heat dissipation method of forced air cooling to dissipate heat from the compressor s...

Problems solved by technology

But this single cooling method has the following disadvantages: 1) when the ambient temperature is high, in the structure of the oil-free scroll compressor with the wind wheel installed, the cooling effect is not good due to the high room temperature; Due to the high flow rate of the gas discharged from the wheel, when passing through the moving and static scroll, the gas stays on the heat sink for a short time, and cannot fully dissipate heat with the heat sink.

3) The heat dissipation parts do not go deep into the interior of the movable and static scroll, that is, the compression chamber, and cannot quickly and fully take away the large amount of heat generated by the compression chamber
