The invention relates to a flow lattice 10, which comprises a frame 11 and bars 12, which guide the air flow and are fixed to the frame 11, the flow lattice furthermore containing heat transmission elements 15 for melting snow flakes and similar particles. The flow lattice, in relation to the flow, comprises front first bars 13 and, in relation to the flow, rear second bars 14, each bar 14 comprising a collecting channel 18 and heat transmission elements 15, which are arranged in connection with the collecting channel 18 in question. When the air reaches the flow lattice 10, it first runs between the two first bars 13 (arrow L1) connected to a second bar 14 (arrow L2) to its collecting channel 18. In so doing the heat transfer elements 15 in the collecting channel 18 melt the snow flakes and similar particles arriving with the air as they strike the collecting channel 18 after having reached the heated parts of the collecting channel 18. In the flow lattice 10, the air is then moved from the collecting channel 18 from the space between (d2) a first bar 13 and a second bar 14 to the area (d3) between a second bar 14 and another second bar 14, which lies alongside this parallel thereto and away from the flow lattice 10. <IMAGE> |
