Abstract
A cooling unit for cold air generation, in particular for snow-making systems, has a mechanically operating de-icing device which comprises at least one rotary shaft (6), which extends between two tube layers (5) transversely to the refrigerant guide tubes and is displaceable in the longitudinal direction of the refrigerant guide tubes (4), and a rotary drive for rotating the rotary shaft (6). The removal elements (16) are designed as rotary elements which are fastened to the rotary shaft (6) and which remove the ice and frost build-up from the refrigerant guide tubes (4) by means of a rotary movement.
Claims13
A cooling unit for cold air generation, having a plurality of tube layers of refrigerant guide tubes and having a mechanically acting de-icing device for removing ice and frost build-up from the refrigerant guide tubes, the de-icing device comprising removal elements which are displaceable along the refrigerant guide tubes,
- wherein the de-icing device comprises at least one rotary shaft, which extends between two tube layers transversely to the refrigerant guide tubes and is displaceable linearly in a longitudinal direction of the refrigerant guide tubes, and a rotary drive for rotating the rotary shaft, and in that the removal elements are designed as rotary elements fastened to the rotary shaft, which remove the ice and frost build-up from the refrigerant guide tubes by means of a rotary movement,
- wherein the removal elements have contour cutting edges which form a cutting edge profile configured to match an outer profile circumference of the refrigerant guide tubes, each removal element extends over at least one third of the outer profile circumference of the refrigerant guide tubes, and wherein the removal elements rotate and linearly translate along the refrigerant guide tubes.
