Abstract
The utility model relates to an air passage of a cross flow fan, in particular to an air passage of the cross flow fan, which is suitable for being arranged in various equipment for cooling, heating or ventilating; the air passage of the cross flow fan comprises a left and plate and a right end plate which are arranged at two sides of a surrounding plate and a lingual plate, a wind outlet is formed among the surrounding plate, the lingual plate, the left end plate and the right end plate, and the length of the wind outlet is 1, a cavity which is protruded outwards and is used for containing the two ends of a wind wheel is formed on the left end plate and the right end plate, the axial length from the cavity bottom of the left end plate and the cavity bottom of the right end plate is L which is more than 1. The air passage of the cross flow fan has rational structure and simple manufacturing, the air passage can lead the length of the wind wheel and the length of the wind outlet to be same or close, even the length of the wind wheel is more than that of the wind outlet, the wind volume can reach the highest value under the same condition that the cross flow fan has the same specification, and the working efficiency is the highest.
Description
Technical field
The utility model relates to a kind of cross flow fan, relate in particular to a kind of be suitable for being installed in be used for the air channel of the cross flow fan that cools off, heat or ventilate in the various device.
Background technique
At present, the air channel of known cross flow fan mainly is made up of first member plate, right end plate, coaming plate, hyoplastron, with the installation position of miscellaneous equipment at the position, peripheral edge of two end plates, or coaming plate bottom, or on the hyoplastron.Wind wheel places in the air channel, and by the driven by motor running, gas enters wind wheel from a side of rotor outer rim, passes wind wheel inside then and discharges from opposite side.Existing first member plate and right end plate are flat board, and first member plate is to the distance of right end plate and the equal in length of exhaust outlet, and the length of existing wind wheel is less than exhaust outlet length and just can be installed in the air channel.Because the length of wind wheel is less than exhaust outlet length, so the air quantity of cross flow fan can not reach maximum, has influence on the usability of blower fan.How to make the air quantity of the cross flow fan of same specification can reach maximum, just those skilled in the art's problem demanding prompt solution.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of air channel of cross flow fan, it is rational in infrastructure, make simple, this air channel can make the length of wind wheel identical or close with the length of exhaust outlet, even greater than the length of exhaust outlet, the cross flow fan that makes same size air quantity under the same conditions reaches maximum, and working efficiency is the highest.
The utility model solves the problems of the technologies described above by following technical proposals: a kind of air channel of cross flow fan, comprise the first member plate and the right end plate that are arranged on coaming plate, hyoplastron both sides, be formed with exhaust outlet between described coaming plate, hyoplastron, first member plate, the right end plate, the length of described exhaust outlet is l, all be formed with the cavity that is used to hold the wind wheel two ends of outside protrusion on described first member plate and the right end plate, the cavity bottom of described first member plate is L to the axial length of the cavity bottom of right end plate, described L＞l.
As preferably, described cavity is frustoconic shape.
Adopt the model utility of the technical program, its beneficial effect is: the cavity that is used to hold the wind wheel two ends that all is formed with outside protrusion on described first member plate and the right end plate, the cavity bottom of described first member plate is L to the axial length of the cavity bottom of right end plate, described L＞l.This design makes can hold longer wind wheel in the air channel of cross flow fan of same specification, makes the length of wind wheel can guarantee cross flow fan air quantity maximum under the same conditions more than or equal to the length in air port, and working efficiency is the highest.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Describe in further detail below in conjunction with 1 pair of the utility model of accompanying drawing:
As shown in Figure 1, a kind of air channel of cross flow fan, comprise the first member plate 1 and the right end plate 3 that are arranged on coaming plate 2, hyoplastron 5 both sides, be formed with exhaust outlet 6 between described coaming plate 2, hyoplastron 5, first member plate 1, the right end plate 3, the length of described exhaust outlet 6 is l, all be formed with the cavity 4 that is used to hold the wind wheel two ends of outside protrusion on described first member plate 1 and the right end plate 3, described cavity 4 is frustoconic shape.The cavity bottom of described first member plate 1 is L to the axial length of cavity 4 bottoms of right end plate 3, described L＞l.Described cavity has got out of the way suitable space for the wind wheel two ends, makes the two ends of wind wheel can stretch into end plate as far as possible, and the length of wind wheel can be identical with the length of exhaust outlet or close, even the length of being a bit larger tham exhaust outlet, under the same terms,, make the air quantity of blower fan also increase because the length of wind wheel has increased.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
