Embodiment Construction
[0013] Such as figure 1 As shown, a power transmission device with a heat dissipation function includes a package case 1, a heat conduction sheet 2 arranged on the package case, and an active element 3 inside the package case. The package case 1 and the heat conduction sheet 2 It is made of aluminum foam with strong fire resistance, insulation and thermal conductivity. The heat conducting sheet 2 is T-shaped, which increases the heat dissipation function of the transmission device. Aluminum foam has light weight and high specific rigidity. The aluminum foam with through-hole structure has good heat dissipation under convection conditions because its holes are interconnected.
[0014] The gap distributed along the radial direction of the heat conduction sheet 2 is smaller than the arm length of the T-shaped heat conduction sheet 2, and the gap distributed along the axial direction of the heat conduction sheet 2 is smaller than the height of the T-shaped heat conduction sheet 2...

Description
technical field [0001] The invention relates to an electric energy transmission device, in particular to an electric energy transmission device with a heat dissipation function. Background technique [0002] The power transmission equipment is a multi-phase packaged open-air high-voltage switchgear. Such power transmission devices consist of a number of individual modules. Each module has an encapsulating case. Various active components are arranged inside the package case. Depending on the configuration of the active components, thermal energy is released within the encapsulation housing due to the heating effect of the current. This heat is taken into account in the dimensioning of such power transfer devices. [0003] Critical temperatures rarely occur during normal operation. Power transfer devices are designed for this critical temperature. In order to withstand such loads reliably, correspondingly large-volume electrical energy transmission devices are used. [...
