Description

Refrigerating fan Technical Field The utility model relates to the technical field of fans, in particular to a refrigeration fan. Background The conventional fan generates air flow through the rotation of the fan blades, and the flowing air is used for being contacted with the human body surface, so that part of heat on the human body surface is taken away, the generated cooling sensation is poor, and the temperature of the skin of the human body cannot be reduced rapidly. Therefore, a refrigerating fan appears in the market, a refrigerating sheet is arranged on an air outlet shell of the refrigerating fan, a radiating fin is connected to a hot surface of the refrigerating sheet, and heat absorbed by the radiating fin is blown out from an air outlet between grid bars of the air outlet shell by using fan blades, so that a cold surface of the refrigerating sheet can be rapidly refrigerated, the cold surface of the refrigerating sheet can be conveniently attached to the skin of a human body, and a user can be rapidly cooled. The prior art has the defects that in order to increase the heat radiating area of the heat radiating fin, the heat radiating fin in the prior art is generally extended towards the position between the fan blade and the air outlet, but the fins are positioned on the air outlet path of the fan blade, so that the air outlet of the fan blade can be disturbed by the fins, the air outlet efficiency is reduced, the heat radiating effect is limited, and the refrigerating effect is influenced.
