The integrated fan shroud comprises a fan net shroud and a wind guide ring, wherein the wind guide ring comprises a cylindrical periphery wall on which a first air hole and a second air hole on two opposite ends are arranged; the fan net shroud is arranged at the first air hole; a radically protruded chamfer type flange is formed at the second air hole on the periphery wall; partial edges of the chamfer type flange are cut; and the chamfer type flange is the mounting part for the integrated fan shroud.
Description
Technical field
The utility model relates to fan guard.
Background technique
Be as described in 200810131913.1 the disclosed technological scheme of Chinese patent application as application number, axial-flow blower in the outdoor unit of air-conditioning, the outdoor heat converter ambient air is blown in pressure, thereby improves the heat exchange efficiency of the freezing mixture that flows through outdoor heat converter.Fan screen prevents that human body or other objects from entering the fan of high speed rotating, prevents that security incident from taking place, and the protection draught fan.The outside of fan as shown in Figure 1, mainly contains fan screen 11 and air-ducting ring 12 cooperation installations at present.Guard adopts the steel wire electrostatic spraying, and air-ducting ring adopts high-quality galvanized sheet surface electrostatic painting, and fan is installed in the space of guard and air-ducting ring formation.When this assembles at fan, have complex manufacturing technology and making, installation cost height, easy problem such as get rusty.
The model utility content
The purpose of this utility model is to provide a kind of one-body molded fan guard, and it has installs simple, production process characteristic of simple.
One-body molded fan guard of the present utility model, comprise fan screen and air-ducting ring, be characterized in that by formed in mould one working of plastics, air-ducting ring comprises perisporium cylindraceous to this one-body molded fan guard on the whole, perisporium has first air port and second air port that is positioned at opposite end, fan screen is arranged on first air port, and in second air port, perisporium has radially outstanding corner cut type flange, the part edge of corner cut type flange is cut, and this corner cut type flange is the assembly department of this one-body molded fan guard.
Described one-body molded fan guard, its further characteristics be, the perisporium of air-ducting ring is for extending out shape, and fan screen is positioned at the small end that extends out shape.
Described one-body molded fan guard, its further characteristics are, fan screen comprises center plate, radial rib and sealing rib, a plurality of radial ribs are radial extension from center plate guide solar or lunar halo perisporium inboard, and a plurality of sealing ribs are the radially evenly distribution and with radial rib crossing of center at center plate with the center plate.
Described one-body molded fan guard, its further characteristics are that diametric two edges of corner cut type flange are cut.
Described one-body molded fan guard, its further characteristics are to be installed on the axial-flow blower that diameter is 710mm.
This one-body molded fan guard on the whole by formed in mould one working of plastics, not only the intensity height, be difficult for getting rusty, and reduced production process, be convenient to install, save production cost greatly, plastic material is recyclable, thereby but energy saving consumption.
