摘要： The present invention provides an X-ray generating apparatus with a shield structure (22) having an electron beam collimating aperture and heat transfer device. The shield structure is made of thermally conductive material and placed in the discharge space between an electron source (16) and rotating anode target (20). The shield structure is formed by a concave top surface (21) facing the electron source (16), a flat top surface (23) facing the anode target (20), and inner and outer walls (25,27) wherein a linear dimension of the inner wall is substantially smaller than the linear dimension of the outer wall (27). The inner wall (25) surrounds the beam collecting aperture. The heat transfer device is placed in a bevelled portion of the shield structure. The heat transfer device includes an extended coiled wire (30 formed from thermally conductive material and conductively attached to the knurled interior of the shield structure to transfer heat to the cooling liquid passing through inflow (24) and outflow (26) chambers of the shield structure (22).
