Abstract

The invention relates to a pressure wave generating device for a low-temperature refrigerator and an assembling method of the pressure wave generating device. The device comprises a main base and two pressure wave generating mechanisms, and the two pressure wave generating mechanisms are connected to the two ends of the main base correspondingly. Each pressure wave generating mechanism comprises a piston head, a piston rod assembly, a base, a diaphragm spring assembly and a motor assembly. Each piston rod assembly comprises a front piston rod and a rear piston rod, wherein the front piston rod is detachably connected with the rear piston rod, the front piston rod and the rear piston rod are coaxially arranged, and the front piston rod and the rear piston rod are both subjected to light-weight cutting in advance. Compared with the prior art that a piston rod is of an integrated structure, the piston rod divided into the two parts is easier subjected to light-weight cutting, and the advantages of high refrigeration efficiency and the like are achieved.

Description

technical field [0001] The invention relates to the field of cryogenic refrigerators, in particular to a pressure wave generating device for cryogenic refrigerators and an assembly method thereof. Background technique [0002] Small regenerative low-temperature refrigerators are usually driven by linear motors. The gap sealing technology is used between the piston and the cylinder to achieve oil-free lubrication. It has a wide cooling temperature range, high cooling efficiency at low temperatures, simple structure, and no working direction restrictions. The refrigerant is environmentally friendly, the cooling capacity is easy to adjust, the operating noise and vibration are small, the service life is long and the reliability is high, and many other advantages. It has a wide range of applications in the fields of aerospace, high-temperature superconductivity, infrared detection, and biomedicine. [0003] At present, the pressure wave generating devices of small cryogenic ref...
