Abstract
The invention relates to the technical field of refrigeration compressors, in particular to a double-cylinder rotary compressor; the double-cylinder compressor comprises a first cylinder, a second cylinder and a partition plate arranged between the first cylinder and the second cylinder, wherein a first rotary compression unit and a second rotary compression unit are respectively arranged in the first cylinder and the second cylinder and driven by the axial rotation of a motor, and a hollow cavity is arranged in the partition plate; by using the double-cylinder compressor, the hollow cavity is arranged in the partition plate, so that the heat transfer capacity is reduced, the solid partition plate used in the conventional double-cylinder compressor is avoided, the heat transfer between the compression cavity and the suction cavity at two sides of the partition plate of the compressor is greatly reduced, the refrigerating capacity of the compressor is increased, the power consumption of a motor is reduced, and the energy efficiency of the compressor is improved.
Description
Technical field
The present invention relates to technical field of refrigeration compressors, relate in particular to a kind of duplex-cylinder rotary compressor.
Background technique
Refrigeration compressor is that compression refrigerant makes it participate in the circuit nucleus equipment in refrigerator, the air-conditioning system, and liquor separator is one of important component of compressor (especially rotary compressor); Duplex-cylinder rotary compressor can effectively reduce the Influence from Eccentric that compression unit produces, thereby be used widely owing to two rotary compression elements that are provided with of symmetry; Duplex cylinder compressor generally comprises first cylinder 1, second cylinder 2 and is arranged on dividing plate 3 (see figure 1)s between first, second cylinder 1,2, be respectively arranged with in first, second cylinder 1,2 by motor 4 axially rotation drive first, second rotary compression elements 5,6; Two compression units of duplex cylinder compressor are separately positioned on the both sides of dividing plate 3, when the compressor unit of one of them cylinder compressed, the compression unit of dividing plate 3 opposite side cylinders was for suction condition, and the cylinder cavity temperature is higher during owing to compression, and the temperature of air aspiration cavity is lower, dividing plate 3 is generally entity state, and metal partion (metp) 3 temperature conductivities are fine, and the heat in high temperature compressed chamber conducts to the low temperature air aspiration cavity, the air aspiration cavity temperature rises, pressure also raises, and has reduced gettering quantity, thereby refrigerating capacity is reduced; And after heat passed to air aspiration cavity by dividing plate 3, the temperature of compression chamber reduced, and pressure also lowers, and has increased compression power consumption; In the compressor operating process, owing to carry out the heat exchange that heat transmission mutually causes by dividing plate 3, both reduced refrigerating capacity like this, and increased power consumption again, the compressor efficiency reduces greatly.
Summary of the invention
The present invention be directed to the problem that present duplex cylinder compressor well causes the compressor efficiency to reduce in compression process central diaphragm heat transfer property, and a kind of duplex cylinder compressor that reduces above influence is provided.
For reaching above purpose, adopt following technological scheme:
A kind of duplex-cylinder rotary compressor, described compressor include first cylinder, second cylinder and are arranged on dividing plate between first, second cylinder, are respectively arranged with in first, second cylinder by motor shaft and drive first, second rotary compression element to rotation; Be provided with hollow cavity in the described dividing plate.
Wherein said dividing plate is divided into first, second metal lamellar body, and first, second metal lamellar body clamping forms dividing plate, between first, second metal lamellar body hollow cavity is set.
The wherein said first metal lamellar body is or/and the outer edge of the second metal lamellar body is provided with convex ring edge respectively, and inside and outside convex ring edge forms circular groove after the clamping of two metal sheets body, and circular groove has constituted hollow cavity.
Wherein said dividing plate is provided with several horizontal perforations in the direction of vertical axial, and horizontal perforation has formed the hollow cavity of dividing plate.
Beneficial effect of the present invention is: duplex cylinder compressor of the present invention has first cylinder, second cylinder and is arranged on dividing plate between first, second cylinder, be respectively arranged with in first, second cylinder by motor shaft and drive first, second rotary compression element, be provided with hollow cavity in the dividing plate to rotation; Use duplex cylinder compressor of the present invention, hollow cavity is set in dividing plate, reduced the ability of hot transmission, avoided existing duplex cylinder compressor to use solid dividing plate, reduce the compression chamber of compressor disk both sides and the heat transmission between the air aspiration cavity greatly,, increased the refrigerating capacity of compressor than the duplex cylinder compressor of prior art, reduce motor power consumption again, promoted the compressor efficiency.
Description of drawings
Fig. 1 is the duplex cylinder compressor structural representation of this prior art;
Fig. 2 is the embodiment of the invention 1 structural representation;
Fig. 3 is the embodiment of the invention 2 structural representations.
Embodiment
Below in conjunction with accompanying drawing the present invention is further specified:
Embodiment 1, as shown in Figure 2: a kind of duplex-cylinder rotary compressor, compressor includes first cylinder 1, second cylinder 2 and is arranged on dividing plate 3 between first, second cylinder 1,2, be respectively arranged with in first, second cylinder 1,2 by motor 4 axially rotation drive first, second rotary compression elements 5,6; Dividing plate 3 is that first, second metal lamellar body 31,32 constitutes, and first, second metal lamellar body 31,32 clampings form dividing plate 3, and 31,32 of first, second metal lamellar bodies are provided with hollow cavity 7.Hollow cavity 7 can be formed by multiple mode, as a specific embodiments of the present invention, the outer edge of the first metal lamellar body 31 and the second metal lamellar body 32 is provided with convex ring edge 34 respectively, and inside and outside convex ring edge 34 forms circular groove after the clamping of two metal sheets body, and circular groove has just formed hollow cavity 7.As those skilled in the art, can have a variety of technical approach to form hollow cavities 7: as the edge of a metal lamellar body therein convex ring edge is set, another metal lamellar body is a plain film, and clamping open loop space in the back forms together also can form hollow cavity; Wherein a metal lamellar body is provided with outer edge convex ring edge is set respectively for another example, a metal lamellar body is a plain film in addition, and clamping back together forms between closed emptying, also can form hollow cavity, or the like technological means form commonly used all can form hollow cavity, enumerate not exclusively one by one at this.Being connected and fixed of first, second metal lamellar body can be fixed together by modes such as riveted joint, welding, screwings, and two cylinders with two compression units are assembled together again.The two metal sheets body is by being assembled together by bolt 8 with first, second cylinder 1,2 after being welded to connect again in the present embodiment; Can also the two metal sheets body independent respectively and the assembling of two cylinders re-use and connect the cylinder mode and make the two metal sheets body formation hollow cavity that is connected together.
Above embodiment is vertical duplex cylinder compressor; but the present invention not only is confined to vertical duplex cylinder compressor; in the duplex cylinder compressor of horizontal or inclined, also can implement and protect; certainly need not creative work, those skilled in the art can also apply to this technology in the dividing plate of multi-cylinder rotary compressor.
The above embodiment, it is preferred embodiments of the present invention, be not to limit the scope of the present invention,, all should be included in the patent claim of the present invention so all equivalences of doing according to the described structure of the present patent application claim, feature and principle change or modify.
