Abstract

The invention relates to the technical field of air compressors, and discloses an oil-free piston type air compressor for a new energy vehicle. The oil-free piston type air compressor for the new energy vehicle comprises a crank case, a cylinder body and a cylinder head assembly, wherein a piston cylinder is arranged in the cylinder body; the cylinder body is arranged above the crank case and is connected with the crank case; the cylinder head assembly is arranged above the cylinder body and is connected with the cylinder body; a low-pressure heat exchanger connected with the crank case is arranged on the front side of the cylinder body; a manifold block connected with the cylinder body is arranged at the right end of the cylinder body and is connected with the low-pressure heat exchangerthrough a first water inlet pipe; a first water outlet is formed in the left end of the low-pressure heat exchanger and is connected with the cylinder head assembly through a first drainage pipe; a high-pressure heat exchanger connected with the crank case is arranged on the back side of the cylinder body; the manifold block and the high-pressure heat exchanger are connected through a second waterinlet pipe; and a second water outlet is formed in the left end of the high-pressure heat exchanger and is connected with the cylinder head assembly through a second drainage pipe. The oil-free piston type air compressor for the new energy vehicle provided by the invention adopts water-cooling and air-cooling double-acting cooling manners so as to be sufficient in cooling and better in effect.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to an oil-free piston air compressor for new energy vehicles. Background technique [0002] Oil-free piston air compressors for new energy vehicles mainly include crankcases, cylinder blocks, cylinder heads, motors, crankshafts, connecting rods, pistons, cooling fans and other components. Most of the current oil-free piston air compressors use single-stage compression method, this single-stage compression method has high energy consumption and low gas pressure; in addition, these oil-free piston air compressors currently use fan forced air cooling to dissipate heat, which mainly relies on convection conduction to dissipate heat. The thermal efficiency is also low. The heat of the air compressor cylinder block, cylinder head, especially the internal moving parts such as connecting rods and pistons accumulates for a long time, and the temperature cannot be quickly and effectiv...
