Problems solved by technology

[0008] In addition, since the pump side bearing is installed separately from the cylinder, it must be assembled in a concentric state.
Also, since the bore of the cylinder is eccentric, it must be assembled in the correct position

Embodiment 1

[0031] figure 1 It is a sectional view showing the Example of this invention. The stator 3 of the motor is installed on the outer side of the thin-walled airtight container 1; the rotor 4 of the motor is arranged on the inner side. The rotational force of the rotor 4 is transmitted to the pump mechanism part 5 through the drive shaft 6 . In addition, the pump mechanism part 5 is fixed in the thick-walled airtight container 2 . In addition, the suction pipe 13 is provided at the upper end on the suction side end plate 11, and the discharge pipe 14 is provided above the drive shaft 6 on the discharge side end plate 12. 7 is a cylinder bearing, which also serves as a bearing for the drive shaft 6 and forms a pump. chamber cylinder. In addition, it has a structure in which the thick-walled airtight container 2 is inserted into the thin-wall airtight container 1 .

Abstract

The present invention provides a refrigeration pump having a structure in which a pump mechanism is installed inside a thick-walled airtight container, and the thick-wall airtight container is inserted and welded inside the thin-wall airtight container. According to this structure, the axis center can be easily aligned only by improving the dimensional accuracy of the thick-walled airtight container. This solves the problems in the previous refrigeration pumps that due to the large number of parts and the accumulation of tolerances of each part, it is difficult to correct the concentricity of the drive shaft and the bearing. It is difficult to perform crimping while maintaining dimensional accuracy.

Description

technical field [0001] The present invention relates to a refrigeration pump for a cooling device that efficiently cools highly exothermic semiconductor elements and the like by utilizing the phase change of evaporation and condensation of refrigerant liquid. Background technique [0002] In the existing refrigerating pump (Japanese Patent Application Ping 2-283887 (1990.11.21)), such as Figure 5 , Image 6 As shown, there is provided a thick-walled intermediate case 52 covered by a thin-walled airtight container 51 for supporting the pump mechanism part 53 . [0003] In addition, a hole 54 is provided in the rotor of the motor unit as a passage of the refrigerant liquid, and a suction port 61 provided in the suction plate 55 is provided to face upward. Furthermore, the suction pipe 56 and the discharge pipe 57 are also arranged on the central axis of the refrigeration pump. [0004] In addition, the pump-side bearing 58 has a separate structure from the air cylinder 59 t...
