AI Technical Summary

Technical Problem

In existing compressors, there is a heat transfer path from the high-temperature side of the cylinder to the suction side, which leads to an increase in suction side temperature and a decrease in compressor performance.

Method used

A first heat insulation hole is provided on the partition plate between the intake and exhaust holes of the cylinder and is positioned opposite to the intake and exhaust holes of the cylinder in the axial direction of the partition plate. In addition, a second heat insulation hole is provided on the partition plate opposite to the second area between the intake and exhaust holes of the cylinder. A heat insulation layer is provided on the outer peripheral wall of the partition plate opposite to the intake hole to suppress heat transfer.

Benefits of technology

It effectively suppresses heat transfer from the high-temperature side of the cylinder to the intake side of the cylinder through the partition, reduces the intake side temperature, increases the refrigerant intake volume, and improves compressor performance.

Abstract

The application provides a partition plate, a compressor pump body, a compressor and an air conditioner. The partition plate is arranged between two adjacent cylinders. The partition plate comprises an axial first end surface and an axial second end surface. The axial first end surface and the axial second end surface are oppositely arranged. A first heat insulation hole is arranged in the interior of the partition plate. The first heat insulation hole is located between the axial first end surface and the axial second end surface and does not contact the axial first end surface and the axial second end surface respectively. In the axial direction of the partition plate, the first heat insulation hole is opposite to a first area between a suction hole of the cylinder and an exhaust hole. According to the application, heat transfer from the high-temperature side of the cylinder to the suction side of the cylinder through the partition plate body can be inhibited, the suction temperature rise of the suction side of the cylinder is reduced, the refrigerant suction amount is increased, and the compressor performance is improved.
