ABSTRACT:
The present invention provides a low smoke screen handler for smoke generators comprising a housing provided therein with a compressor, condensing coils, evaporating coils, and capillaries. After being compressed by the compressor, the high temperature gas refrigerant undergoes heat exchange in the condensing coils to dissipate heat from the refrigerant, heat being absorbed in the evaporating coils to gasify the refrigerant, and an evaporating chamber being formed in the area of the evaporating coils so as to cool other objects, characterized in that the evaporating coils are further covered with a housing and a warm keeping material to form a tunnel type evaporating chamber, one side thereof having a relatively small round opening for connecting to a smoke generator and the other side having a wider opening such that the smoke generated by the smoke generator is introduced through the round opening on the one side is cooled down rapidly to a low temperature smoke screen by multi-stage cooling in the evaporating chamber, and then discharged from the opening on the other side, thus providing an improved smoke screen handler for the smoke generator.
