Embodiment Construction
[0041] Below in conjunction with embodiment technical solution of the present invention is made more specific description:
[0042] A thermal design method for TEC type selection of a radar incubator, comprising the following steps:
[0043] Step 1, according to the requirements of the telecommunications index, determine the current I and voltage U supplied to the semiconductor cooler (TEC) in advance;
[0044] Select a type of semiconductor refrigerator, select the hot surface temperature Th of the semiconductor refrigerator according to the performance diagram of the cooling power changing with the temperature difference in the model specification of the semiconductor refrigerator, and then obtain the temperature difference DT according to the target temperature T:
[0045] DT=Th-T
[0046] According to the temperature difference DT and the current value I supplied to the semiconductor refrigerator, and referring to the performance diagram of the cooling power changing with...
