This paper introduces a lumped parameter thermal network (LPTN) model for the optical system of aerial cameras, aiming to serve as a guideline for their thermal design. By optimizing the thermal resistances associated with convection and radiation while considering the camera\u2019s unique internal architecture, this model endeavors to improve the accuracy of temperature predictions. Additionally, the proposed LPTN framework enables the establishment of a heat leakage network, which offers a detailed examination of heat leakage paths and rates. This analysis offers valuable insights into the thermal performance of the camera, thereby guiding the refinement of heating zones and the development of effective active control strategies. Operating at a total power consumption of 26 W, the thermal system adheres to the low-power limit. Experimental data from thermal tests indicate that the temperatures within the optical system are maintained consistently between 19 \u00b0C and 22 \u00b0C throughout the flight, with temperature gradients remaining below 3 \u00b0C, satisfying the temperature requirements. The proposed LPTN model exhibits swiftness and efficacy in determining thermal characteristics, significantly facilitating the thermal design process and ensuring optimal power allocation for aerial cameras.<\/jats:p>","DOI":"10.3390\/s24123982","type":"journal-article","created":{"date-parts":[[2024,6,19]],"date-time":"2024-06-19T11:47:17Z","timestamp":1718797637000},"page":"3982","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Lumped Parameter Thermal Network Modeling and Thermal Optimization Design of an Aerial Camera"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-9117-6307","authenticated-orcid":false,"given":"Yue","family":"Fan","sequence":"first","affiliation":[{"name":"College of Mechanical Engineering, Chengdu University, Chengdu 610106, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Feng","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Chengdu University, Chengdu 610106, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhenxing","family":"Ren","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Chengdu University, Chengdu 610106, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bingqi","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Chengdu University, Chengdu 610106, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dazhi","family":"Wang","sequence":"additional","affiliation":[{"name":"Institute of Optics and Electronics, Chinese Academy of Sciences, Chengdu 610209, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Held, K.J., and Robinson, B.H.
