Embodiment 1
[0048] Embodiments of the present invention will be described below with reference to the drawings. figure 1 Be equipped with the refrigerant circuit diagram (embodiment 1) of heat exchanger embodiment of the present invention, figure 2 It is a perspective view of the heat exchanger of the present invention viewed from one side, image 3 from the other side figure 2 Perspective view of a heat exchanger.
[0049] Among the figure, 1 is an internal intermediate pressure type multilayer (two-layer) compression type rotary compressor using carbon dioxide as a refrigerant, and this rotary compressor 1 includes: a cylindrical airtight container 2 made of steel plates; The electric element 4 is arranged and accommodated on the upper side of the inner space of the airtight container 2; Element 10 (first layer) and second rotary compression element 12 (second layer) constitute.
[0050] The airtight container 2 includes: a container body 2A, which accommodates the electric eleme...
Embodiment 2
[0073] Figure 6 Shown is an enlarged view of a main part of a gas cooler 24 which is a heat exchanger in another embodiment of the present invention. This gas cooler 24 has substantially the same structure as that of the above-mentioned embodiment. The different parts are explained below. The same reference numerals are assigned to the same parts as those in the above-mentioned embodiments, and description thereof will be omitted. that is, Figure 6 As shown, the elbow pipe 36 does not extend the tip of the end portion 37 to the tube plate 27, but is formed to have a short length from the tube plate 27 to a position separated by a predetermined distance.
[0074] Thus, since the end portion 37 of the elbow pipe 36 is formed shorter than in the first embodiment, the operability when inserting the end portion 37 of the elbow pipe 36 into the end portion 33 of the main pipe 32 can be improved. Since the processing operation of the end portion 37 of the elbow pipe 36 can also...

[0076] Figure 7 Shown is an enlarged view of a main part of a gas cooler 24 which is a heat exchanger in another embodiment of the present invention. This gas cooler 24 has substantially the same structure as that of the above-mentioned embodiment. The different parts are explained below. The same reference numerals are assigned to the same parts as those in the above-mentioned embodiments, and description thereof will be omitted. That is, the main pipe 32 is formed to have an outer diameter of 7.94 mm, a wall thickness of 1.00 mm, and an inner diameter of 5.94 mm ( Figure 12 Shown in column 1 of this technique) is cylindrical in shape, and is formed in a linear shape with approximately the same wall thickness from one end to the other end, and the approximately central part is bent to form a U-shape.
[0077] The elbow pipe 36 has an outer diameter of 6.35 mm and a wall thickness of 1.00 mm, and is formed in a cylindrical shape with substantially the same wall thickness ...
