  • Spraying tube device and heat exchanger using the same
    Patent number: 9314802
    Abstract: Disclosed is a spraying tube device capable of, even in a case where a spray solution having low latent heat is used in a falling film type evaporator, uniformly spraying the spray solution to a heat-transfer tube, and a heat exchanger using the spraying tube device. The spraying tube device includes: a spraying tube configured to eject a spray solution M upward through ejection holes arranged along a tube axis C; a cover arranged above the spraying tube and configured to receive the ejected spray solution M and cause the spray solution M to flow through a space S between the cover and the spraying tube to flow downward on an outer surface of the spraying tube, and fins configured to uniformize in a tube axis C direction a distribution of the spray solution M having flowed downward from the cover.
