ものとする。Figure 1 is a partial perspective view of the blade shape of a conventional axial flow blower, Figure 2 is a vector diagram showing the relationship between inflow and outflow airflow, and Figure 3 is a low-temperature diagram showing one embodiment of this invention. FIG. 4 is a partial perspective view of the blade shape in a high temperature state. In the figure, 6 is the suction side vane, 7 is the pressure side vane, 6b is the joint, 8 is the leading edge joint, 9 is the trailing edge joint, and 10 is the radius of curvature of the suction side vane. , 11 are warp lines. Note that the same reference numerals in each figure indicate the same or corresponding parts.

Claims

[Scope of utility model registration request]

(1) A vane plate with a large coefficient of thermal expansion connected to the boss portion of the impeller, and heat disposed on the pressure side of the vane plate and joined to the vane plate only at the leading and trailing edges in the direction of rotation. An axial flow blower characterized in that its blades are composed of blades with a small coefficient of expansion.

(2) The axial flow blower according to claim 1, wherein the front edge and the rear edge are joined continuously.

(3) The axial flow blower according to claim 1, wherein the front edge and the rear edge are joined discontinuously.

(4) The axial flow blower according to claim 1, wherein one of the leading edge portion and the trailing edge portion is joined continuously and the other is joined discontinuously.
