Embodiment 1

[0083] Example 1:

[0084] (1) Calculate the volumetric power density according to the relevant physical parameters of the components that require additional heat dissipation inside the cabinet, and select the heat dissipation method accordingly, generally forced air cooling and forced liquid cooling:

[0085] The cabinet system in this embodiment 1 is such as figure 2 As shown, the device that requires additional heat dissipation inside is a TR component. According to the three-dimensional size of the TR component, the volume of the component is S; the heat generation is Q; according to the conventional volume power density calculation formula q=Q / S, Get the volumetric power density q of the TR module. Since q3 , so in this embodiment 1, the forced air cooling cooling method is selected.

[0086] (2) Calculate the heat transfer coefficient of the inner and outer surfaces of the cabinet by using the relevant similarity criterion numbers obtained by the similarity principle,...

Abstract

The present invention relates to the field of thermal simulation design, and more specifically to a thermal design method for a radar electronic cabinet system. The method comprises the following steps: selecting a heat-dissipating manner; obtaining the heat transfer amount and the radiant heat exchange amount between the air in the cabinet and the outside air; solving the air volume required for cooling the entire cabinet; calculating the total pressure drop; selecting specific heat-dissipating components; establishing a three-dimensional model of the radar electronic cabinet system; establishing a three-dimensional grid computing domain; carrying out simulation calculation on the radar electronic cabinet system to obtain an initial simulation result; and establishing contour lines of temperature distribution and fluid flow traces, and improving an internal structure and layout of the cabinet which does not satisfy the working requirements or re-selecting a heat-dissipating manner. According to the method disclosed by the present invention, the temperature distribution and fluid flow condition of the radar electronic cabinet system in use can be accurately simulated and predicted, so that the optimization and improvement functions of the layout and the heat-dissipating manner of the electronic equipment in the cabinet can be realized.

Description

technical field [0001] The invention relates to the field of thermal simulation design, in particular to a thermal design method for a radar electronic cabinet system. Background technique [0002] Radar is a complex and huge electronic system, which integrates a large number of electronic components of various specifications and models, and has always had high requirements for heat dissipation. With the rapid development of modern radar technology and the continuous improvement of power device manufacturing technology, the continuous improvement of radar assembly density and power density has become an important symbol of current radar development. The radar electronic cabinet is the main carrier for radar electronic equipment. Whether the temperature distribution of the radar electronic cabinet system is reasonable is the prerequisite for the normal operation of the radar. The use of field experiments to test the performance and indicators of the cabinet system can no lon...
