[0027] see figure 2 , The present invention provides an oil heating mechanism for an explosion-proof refrigerant compressor, the oil heating mechanism includes a casing 1 , an explosion-proof introduction device 2 and an oil heater 3 .

[0028] The casing 1 is a part of the oil tank casing of the compressor, and the casing 1 is provided with a chamber 11, which is formed inside the casing 1, and the chamber 11 can be a long space, the chamber The length of the chamber 11 is greater than that of the oil heater 3 , and the inner diameter of the chamber 11 is greater than the outer diameter of the oil heater 3 , so that the oil heater 3 can be smoothly arranged in the chamber 11 . One end of the chamber 11 is provided with an opening 12 , and the opening 12 communicates with the chamber 11 , so that the oil heater 3 can be inserted into the chamber 11 through the opening 12 . After the oil heater 3 is placed in the chamber 11, the explosion-proof introduction device 2 is arrang...

[0041] see image 3 , in this embodiment, the oil heating mechanism also includes a housing 1, an explosion-proof introduction device 2 and an oil heater 3, the structure of which is roughly the same as that of the first embodiment, and will not be repeated here. This embodiment is the same as that of the first embodiment The main difference is that a heat conduction paste 342 is disposed between the external thread 341 and the internal thread 111 , which can further increase the contact area between the heat dissipation joint section 34 of the oil heater 3 and the housing 1 to increase the heat conduction efficiency.

Abstract

The invention provides an oil heating mechanism for an explosion-proof refrigerant compressor, comprising a housing, an explosion-proof introducing device and an oil heater. The housing is provided with a chamber, one end of which is provided with an opening, the opening is communicated with the chamber, and the explosion-proof introducing device is arranged at the opening. The oil heater has a first end and a second end, the oil heater is disposed in the chamber, the first end of the oil heater is remote from the opening, the second end of the oil heater is adjacent the opening, and the second end of the oil heater is connected with a power cord. The power cord is introduced to the outside of the chamber through the explosion-proof device. By this, the requirements of explosion-proof specifications can be met.

Description

technical field [0001] The invention relates to an oil heating mechanism, in particular to an oil heating mechanism of an explosion-proof refrigerant compressor used in an explosion-proof environment. Background technique [0002] Existing refrigerant compressors are equipped with an oil heater to maintain the temperature of the refrigerating oil. If the temperature of the refrigerating oil is too low, it is easy to mix with the refrigerant. After mixing, it is easy to be carried out of the compressor, resulting in oil loss. In severe cases, the compressor will be burned. Generally, the oil heater of the refrigerant compressor is a non-explosion-proof mechanism and cannot be used in an explosion-proof environment. [0003] see figure 1 , which discloses an oil heating mechanism of an existing general refrigerant compressor, the oil heating mechanism includes an oil heater 100, and the oil heater 100 is arranged in a cavity 102 formed in the oil tank shell 101, the cavity O...
