Thermal design method used for radar incubator TEC (Thermo Electric Cooler) model selection

Abstract

The invention relates to a thermal design method used for radar incubator TEC (Thermo Electric Cooler) model selection. The method comprises the following steps that: through theoretical calculation,finishing the model selection of a TEC, a fan and a radiator in a radar incubator; establishing the three-dimensional model of the radiator incubator; establishing a three-dimensional gridding calculation domain; carrying out simulation calculation on the radar incubator to obtain an initial simulation result; and establishing the contour line cloud atlas of temperature distribution and the flow path line of fluid, and improving the internal structure and layout of the radar incubator which does not conform to job requirements. By use of the method, a research and development period can be shortened, and economic benefits are improved. In a practical use process, the radar incubator obtained through the method of the invention has a good heat dissipation effect, and meanwhile, the radar incubator has the advantages of compact structure, miniaturization and good waterproof sealing and electromagnetic shielding effects.

Description

technical field [0001] The invention belongs to the field of thermal simulation design, and in particular relates to a thermal design method for TEC type selection of a radar constant temperature box. Background technique [0002] Thermal design is the thermal design of electronic components. Electronic components in electronic components generally have a temperature range for use, and electronic components generally have a certain amount of heat consumption (calorific value) when they are used. If no measures are taken, electronic components will The ambient temperature inside the device will exceed the allowable temperature range of the electronic components. After exceeding the temperature range of the electronic components, the performance will drop, it will not work until it is burned, and the ambient temperature is too low, and the electronic components will not work properly. Due to the large number of electronic modules in the box, and the development of electronic c...

[0002] Thermal design is the thermal design of electronic components. Electronic components in electronic components generally have a temperature range for use, and electronic components generally have a certain amount of heat consumption (calorific value) when they are used. If no measures are taken, electronic components will The ambient temperature inside the device will exceed the allowable temperature range of electronic components. After exceeding the temperature range of electronic components, there will be performance degradation, failure to work until it is burned, and the ambient temperature is too low, and electronic components cannot work normally.

Due to the large number of electronic modules in the box, and the development of electronic components in the direction of miniaturization and light weight, the volume power density will inevitab...
