Modular heat dissipation structure of power supply and distribution load device

Abstract

The invention belongs to the technical field of heat dissipation, and specifically relates to a modular heat dissipation structure of a power supply and distribution load device. The modular heat dissipation structure is characterized in that one side of the load device is provided with axial flow fans, and the other side is designed with air outlet mesh openings; power resistors are fixed on radiators, a plurality of radiators are vertically arranged and fixed on support plates through radiating fin fixing strips; upright columns are fixed between the two support plates; the support plates are fixed on a support bar; the support bar is fixed with a front panel and a rear panel; the front panel, the rear panel and the support bar are provided with mounting holes so as to fix an upper coverand a lower cover, and the axial flow fans are fixed on the upper cover; and each axial flow fan aligns to three radiators and performs forced air cooling on the radiators along a fin direction. Themodular heat dissipation structure not only improves the reliability of equipment, but also enables the structure to have inheritability on the basis of ensuring a heat dissipation function, can select an appropriate number of radiators and axial flow fans on the basis of the existing thermal design according to the user power, does not need to perform heat dissipation design again and is wide inapplication occasion.

Description

technical field [0001] The invention belongs to the technical field of heat dissipation, and in particular relates to a modular heat dissipation structure of a power supply and distribution load device. Background technique [0002] The power supply and distribution loader is the equipment used to test the ground power supply and distribution equipment before the launch of the rocket. It is used to equivalent the load on the rocket, verify the load capacity of the ground power supply and distribution equipment, and effectively check the power supply and distribution The failure of the equipment greatly improves the performance of the whole system and reduces the cost. The power supply and distribution load is designed according to the load of the equipment on the arrow. Different equipment requires different equivalent load power, and the load needs to work continuously for a long time, which will generate a lot of heat during use. In order to meet the heat dissipation needs...

Problems solved by technology

The power supply and distribution load is designed according to the load of the equipment on the arrow. Different equipment requires different equivalent load power, and the load needs to work continuously for a long time, which will generate a lot of heat during use. In order to meet the heat dissipation needs, so It is necessary to carry out different heat dissipation designs for power supply and distribution loads with the same function and different power, which is time-consuming and laborious
