| 摘要 |
According to the present invention, disclosed is a wet thermal insulator for preventing coolant natural circulation, which includes: a first thermal insulator protection board which has one plane to be exposed in a compressor space; a second thermal insulator protection board which contacts an outer wall of a compressor; a stacked thermal insulation part which is arranged between the first thermal insulator protection board and the second thermal insulator protection board, and is formed by stacking a wet thermal insulator board comprising a protrusion protruded in a fixed interval along a thickness direction of the first thermal insulator board in plural times; a gap filling band which is installed in a space between the wet thermal insulator boards, in order to prevent the flow of a coolant in the space between the wet thermal insulator boards; and a seal-welding part which is formed between at least two of the wet thermal insulator board, the gap filling band, the first and the second thermal insulator protection board, in order to prevent the coolant from being flowed into the wet thermal insulator board by seal-welding. |
