Two primary factors driven by AM that influence heat exchanger performance are surface roughness and geometry. To better understand these parameters, a range of shell and tube heat exchangers constructed using laser powder bed fusion were evaluated. Of those evaluated, the surface roughness throughout a fourteen-tube, zero-baffle heat exchanger was measured using computed tomography. Between the inner and outer tubes, the inner tube surfaces had a greater surface roughness than the outer by 8.07 μm, while the surfaces at the top of the build volume had higher surface roughness values than the bottom. Dimensionally, the inner tube diameters of this heat exchanger were 0.15 % different from the design value, while the outer diameters were within a 0.84 % difference. Manual measurements across seven other heat exchangers yielded a maximum 1.15 % difference between the design and measured diameters. Across the build volume for all heat exchangers studied, the tube diameters at the top were larger than at the bottom by a maximum of 1.24 % difference. Inconsistent melting throughout the individual parts and the build volume, as well as particle splatter and thermal gradient variation were attributed to the surface roughness and dimensional changes seen. These results strengthen the knowledge of dimensional and surface roughness considerations when designing AM heat exchangers.</div></div>","PeriodicalId":23062,"journal":{"name":"Thermal Science and Engineering Progress","volume":"65 ","pages":"Article 103858"},"PeriodicalIF":5.1,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144632769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Laboratory experiments and numerical simulations using ANSYS analyzed their performance across different ETs (40 and 70 °C), moisture conditions (dry and wet), and insulation thicknesses (20, 35, 50 mm). Rockwool demonstrated the best performance in dry conditions, reducing ETs by up to 30 %, but dropped by 13 % when wet. HSP maintained better stability under wet and extreme ETs, with reductions up to 31 % in base conditions and 57 % at 70 °C. CP was effective in moderate ETs and wet conditions but underperformed at high temperatures. Increasing insulation thickness improved thermal resistance, though the significance reduced beyond 35 mm.

This paper develops a battery TMS that coupled phase change materials (PCM) and immersion cooling for eVTOL. It only uses the PCM to maintain the battery temperature during the flight and restore the solid state of PCM after flight by immersion cooling. Therefore, the coolant and cooling pipes, pumps, and other accessories do not need to be carried on the vehicle, which reduces the weight of the TMS during the flight stage. The theoretical analysis is done for the relation between temperature, heat release, the amount of PCM, and heat exchange of immersion cooling during multiple charge–discharge cycles of the battery pack. Then, the minimum PCM quantity and the minimum initial immersion cooling ability for this TMS are derived, which can be used for its design. Finally, numerical simulations are conducted for a battery pack design with five cells and six PCM packs to validate the above analyses. The TMS can maintain the battery pack under 48 ℃ with initial temperature of 25 ℃ for long-term and multiple work cycles.
