摘要:
The invention relates to a pulse tube refrigerator with an automatic gas flow and phase regulating device, comprising a helium compressor (1), an air distribution valve (11), a drive controller (9), a drive lead (10), a temperature sensor, a temperature measuring lead (8), a heat regenerator, a first-stage pulse tube (5), a second-stage pulse tube (6), a first-stage air reservoir (14) and a second-stage air reservoir (15), wherein said air distribution valve (11) comprises eight independent valves of a first valve (21), a second valve (22), a third valve (23), a fourth valve (24), a fifth valve (25), a sixth valve (26), a seventh valve (27) and an eighth valve (28). The invention can automatically regulate the flow and phase of the air flow entering the heat regenerator or the pulse tube in accordance with the refrigeration condition changes so as to regulate the performance of the refrigerator, maintain an optimized working state of the refrigerator and enhance the efficiency of the refrigerator and the stability of the cooling temperature.
