Description

Technical Field

[0001] The utility model relates to an installation structure of a power supply module composed of a plurality of switching power supplies, in particular to an installation structure of a compact power supply module. Background Art

[0002] As we all know, due to production environment, space, and transportation constraints, the power cabinets and mechanical cabinets for high-power fractional capacity equipment are typically separated rather than integrated, relying on numerous cables to connect them. This is largely due to the 1-2U chassis format of the original power cabinet modules, making integration of the two difficult. This significantly increases production space, transportation, and equipment costs. To address this, all-in-one units (AIOs) have emerged on the market, integrating the power cabinet and mechanical cabinet. However, the large space occupied by the power supply installation structure, especially the heat dissipation structure, within the entire cabinet prevents AIOs from being miniaturized, resulting in high manufacturing and transportation costs. Utility Model Content

[0011] As a preferred solution, in the installation structure of a compact power supply module, an external terminal connected to the input conductive bar in a one-to-one correspondence is provided on the wind shield between the air outlet end of the linear heat dissipation channel and the power module close to the air outlet end of the linear heat dissipation channel.
