Technical Field
[0001] The utility model relates to the technical field of reciprocating piston refrigeration compressors, in particular to a compressor with an exhaust coil for improving efficiency and reducing noise. Background Art
[0002] At present, the structure of a small fully enclosed reciprocating piston refrigeration compressor generally includes a shell, a movement is installed in the shell, the movement is provided with a pump body and a motor, the pump body is provided with an exhaust port, and the shell is provided with an exhaust pipe. The exhaust port and the exhaust pipe are connected through an internal exhaust pipe. Usually, the internal exhaust pipe is arranged in the upper half of the inner cavity of the shell. In order to ensure the lubrication of the moving parts when the compressor is running, a certain amount of refrigeration oil is installed in the shell. When the pump body is running, the refrigeration oil is automatically pumped to the moving parts. Vibration and noise will be generated when the compressor is running. With the development of industry technology, compressor manufacturers are constantly pursuing to improve efficiency and reduce noise, but there are few improvement plans for the exhaust coil. Utility Model Content
[0003] The purpose of the utility model is to solve the problems existing in the above-mentioned existing small-sized fully enclosed reciprocating piston refrigeration compressors and to provide a compressor with an exhaust coil for improving efficiency and reducing noise.
[0004] The specific scheme of the utility model is: a compressor with an exhaust coil for improving efficiency and reducing noise, comprising a shell, an intake pipe and an exhaust pipe are arranged on the shell, a movement is arranged in the shell, a supporting spring is arranged between the bottom of the movement and the bottom surface of the shell, refrigeration oil is arranged in the shell, a pump body is arranged on the upper part of the movement, the pump body is provided with an exhaust port, an exhaust coil is arranged between the exhaust port and the exhaust pipe, the exhaust coil bypasses the gap between the movement and the shell, a cooling section is arranged in the middle of the exhaust coil, the cooling section is located below the movement, and the cooling section is completely immersed in the refrigeration oil.
[0005] Furthermore, the cooling section is in the shape of an arc, and the arc is arranged parallel to the horizontal plane.
[0006] Furthermore, the distance between the cooling section and the bottom surface of the shell is 2-4 cm.
[0007] Furthermore, the distance between the cooling section and the refrigeration oil level is 1-3 cm.
[0008] Compared with the prior art, the utility model has the following advantages: a section of the exhaust coil is immersed in lubricating oil, so that heat exchange occurs between the high-temperature exhaust gas and the refrigeration oil, thereby reducing the exhaust temperature to a certain extent and improving the energy efficiency of the compressor. At the same time, part of the noise generated by the exhaust coil is transmitted in the oil, so it also has a certain noise reduction effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] See also Figure 1-4 The present embodiment is a compressor with an exhaust coil 5 for improving efficiency and reducing noise, comprising a shell 1, on which an intake pipe 2 and an exhaust pipe 3 are provided, a movement 4 is installed in the shell 1, a supporting spring is installed between the bottom of the movement 4 and the bottom surface of the shell 1, refrigeration oil is installed in the shell 1, a pump body is provided on the upper part of the movement 4, the pump body is provided with an exhaust port, an exhaust coil 5 is installed between the exhaust port and the exhaust pipe 3, the exhaust coil 5 bypasses the gap between the movement 4 and the shell 1, a cooling section 6 is provided in the middle of the exhaust coil 5, the cooling section 6 is located below the movement 4, and the cooling section 6 is completely immersed in the refrigeration oil.
[0015] Furthermore, the cooling section 6 is in the shape of a circular arc, which is arranged parallel to the horizontal plane. The cooling section 6 of the utility model can also be arranged in other shapes, the purpose of which is to increase the length of the coil immersed in the refrigeration oil, thereby increasing the cooling effect.
[0016] Furthermore, the distance between the cooling section 6 and the bottom surface of the shell 1 is 2-4cm, and the distance between the cooling section 6 and the refrigeration oil level 7 is 1-3cm, which is specifically set according to the actual compressor structure and size, and the principle is that the exhaust coil 5 does not touch the shell 1 and the movement 4 when the compressor is running. The principle of the utility model is as follows: the exhaust temperature of the compressor is relatively high, and the exhaust first passes through the internal exhaust coil 5, and then is discharged from the exhaust pipe 3 and enters the refrigeration system circulation. Since the exhaust coil 5 of the utility model is provided with a cooling section 6, when the exhaust passes through the cooling section 6, it exchanges heat with the refrigeration oil with a relatively low temperature, thereby reducing the exhaust temperature entering the refrigeration system to a certain extent, achieving the purpose of improving the refrigeration efficiency.
[0017] At the same time, since a section of the exhaust coil 5 is immersed in the refrigeration oil, a part of the noise generated by the exhaust coil 5 is transmitted through the refrigeration oil, which reduces the noise transmission to the outside world, and thus has a certain noise reduction effect.
