Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] see figure 1 , the main components of the water-cooled oil-free scroll compressor of the present invention are a fixed scroll 1 and a movable scroll 2 . There is a water storage cavity on the back of the static scroll 1, that is, the water cooling area. There are a certain number of through holes in the middle of the spiral teeth of the static scroll 1. The distribution of the through holes can be various, and it can be only in the high pressure ratio area. The through-holes are arranged on the scroll teeth, and the distribution density of the through-holes is determined without affecting the stiffness. The distribution of the holes is various, and the embodiment of the present invention provides one of them, such as figure 2 As shown, they are arranged at intervals from inside to outside.

Abstract

The invention provides a water-cooling oil-free scroll compressor. The water-cooling oil-free scroll compressor comprises a static scroll plate and a dynamic scroll plate which are matched with each other, wherein a through hole facing the dynamic scroll plate is formed in a scroll tooth of the static scroll plate; a water inlet is formed in the static scroll plate, and a water-cooling area is arranged on the back of the scroll plate; water in the water-cooling area is guided to a contact part of the static scroll plate and the dynamic scroll plate through the through hole formed in the scrolltooth; an exhaust pipe is arranged on the static scroll plate and is connected with a gas-liquid separator; the water at the contact part of the static scroll plate and the dynamic scroll plate absorbs heat generated by gas compression along with the compression process of the compressor, and formed high-pressure gas with water vapor enters the gas-liquid separator from the exhaust pipe; and water separated by the gas-liquid separator is introduced into the water-cooling area of the static scroll plate through a water inlet pipe. The water-cooling oil-free scroll compressor can meet the purposes of lubrication and heat dissipation of the oil-free scroll compressor at the same time, and on the premise of meeting the gas requirement, the exhaust temperature is lower, the deformation of thedynamic scroll plate and the static scroll plate is small, and the volume efficiency is high.

Description

technical field [0001] The invention belongs to the field of scroll compressors, in particular to a water-cooled oil-free scroll compressor. Background technique [0002] Compared with traditional reciprocating and swash plate compressors, scroll compressors have the characteristics of fewer parts, simple structure, small size, light weight and high reliability. These characteristics are exactly in line with the characteristics of compressors required by new energy vehicles. fit. In order to ensure reliability during operation, traditional scroll compressors are lubricated with oil for the purpose of lubrication and cooling. However, with the development and innovation of technology, the rapid development of the new energy automobile industry and the medical industry, the demand for pure high-pressure gas in specific industries such as proton exchange membrane fuel cells and other industries has increased, while in the field of small displacement , Oil-free scroll compress...
