摘要： PROBLEM TO BE SOLVED: To extend the degree of freedoms of an installing state of a pulse tube while maintaining a refrigerating performance. SOLUTION: In the pulse tube refrigerator 101, a second high temperature end 3b of a pulse tube 3 is disposed above a second low temperature end 3a, and the tube 3 is inclined so that an angle of an acute angle side of an angle formed between an axial line (a cylindrical axis L1 of the tube 3) for connecting the end 3b to the end 3a and a vertical axis L0 is in a range of 70 deg. or below. Since the tube can be inclined and disposed without impairing refrigerating performance by setting an oblique angle to 70 deg. or below, the refrigerator can be mounted at an apparatus having a dimensional limit in a heightwise direction which could not have been mounted in a conventional pulse tube refrigerator.

摘要： PURPOSE:To reduce an occupying space of a main freezer and make a small-sized freezer by a method wherein a compression space, a radiator, a hold over, a heat exchanger and an expansion space are arranged substantially on the same axis. CONSTITUTION:Working gas compressed in a compression spacing 101 is cooled by freezed state generated in the second expansion spacing 209 of a subfreezer 200 when the working gas passes through a radiator 102, the gas passes through a hold over 103, is cooled to a lower temperature, passes through a heat exchanger 104, flows into an expansion spacing 105, is isothermally expanded under an upward movement of a head 109 to generate a freezed state of about 4.2k. For example, the working gas in an expansion spacing 105 passes through the heat exchanger 104 under a downward movement of the head 109. At this time, herium vapor in a tank 103 passes through a pipe 130 and further passes through the inside part of the heat exchanger 104. The herium vapor is cooled by the working gas of about 4.2K to become liquid, the liquid passes through a pipe 129 and is accumulated in a liquid phase part 131a of a tank 131. The working gas passes through the heat exchanger 104 passes in sequence through the hold over 103, and a radiator 102, its temperature is increased and then working gas returns to the compression spacing 101 so as to complete one cycle.

The working gas passes through a hold over 103, is cooled to a further low temperature, passes through a heat exchanger 104, flows into an expansion spacing 105, isothermally expanded through a downward movement of a head 109 so as to generate a freezed state of about 4.2k. The working gas in the expansion spacing 105 passes through the heat exchanger 104. At this time, herium vapor in the tank 103 passes through a pipe 130, flows into the heat exchanger 104, cooled by the working gas of 4.2k passing in the heat exchanger 104 to become liquid, flows in a pipe 129 and then the liquid is accumulated at a liquid phase part 131a of the tank 131.
