Abstract
A fan includes: a first air guide member including a first air guide surface; a second air guide member including a second air guide surface, where the first air guide surface is spaced apart from the second air guide surface; and a plurality of blades connected between the first air guide surface and the second air guide surface. The first air guide surface is configured as a curved surface that protrudes outward or recesses inward along a radial direction of the fan, and/or the second air guide surface is configured as a curved surface that protrudes outward or recesses inward along the radial direction of the fan.
Claims19
A fan, comprising:
- a first air guide member comprising a first air guide surface;
- a second air guide member comprising a second air guide surface, wherein the first air guide surface is spaced apart from the second air guide surface;
- and
- a plurality of blades connected between the first air guide surface and the second air guide surface;
- wherein the first air guide surface is configured as a first curved surface and protrudes outward or recesses inward along a radial direction of the fan, and/or the second air guide surface is configured as a second curved surface and protrudes outward or recesses inward along the radial direction of the fan.
A fan, comprising:
- a first air guide member comprising a first air guide portion extending obliquely outward along a radial direction of the fan;
- a second air guide member comprising a second air guide portion extending obliquely outward along the radial direction of the fan, wherein the first air guide portion is spaced apart from the second air guide portion;
- and
- a plurality of blades connected between the first air guide portion and the second air guide portion;
- wherein the first air guide portion has an obliquely extended length of L3, and the second air guide portion has an obliquely extended length of L4, wherein L3 ≤ L4.
A fan, comprising:
- a first air guide member comprising a first air guide portion;
- a second air guide member comprising a second air guide portion, wherein the first air guide portion is spaced apart from the second air guide portion;
- and
- a plurality of blades connected between the first air guide portion and the second air guide portion;
- wherein along a radial direction of the fan, a first spacing H1 is formed between an end of the second air guide portion adjacent to an upstream side of the fan and an axis of the fan, and a second spacing H2 is formed between an outer peripheral end of the first air guide portion and the axis, wherein H1 < H2.
