Analizë termike Jobs

I need my existing PCB reviewed, verified Deliverables • Design review report showing baseline thermal readings, problem areas, and the chosen improvement strategy • Updated schematic and PCB layout files (Altium/KiCad or native format of my project), plus Gerbers, drill and pick-and-place files ready for fab • Brief design-note explaining every change and the projected temperature drop, backed by simulation plots or measured data The job is complete once the revised board demonstrates the agreed-upon thermal improvement on paper and is ready for prototype manufacture.

I'm seeking an experienced mechanical engineer to develop a building energy model focused on energy modeling to qualify for energy rebates. Ideal skills and experience: - Expertise in energy modeling software like Trane Trace or similar. - Strong background in mechanical engineering principles - Proven track record in energy efficiency projects - Ability to analyze and interpret complex data - Experience with building systems and HVAC Please include relevant experience in your application.

I need an Aspen simulation that focuses on full process design of a heat exchanger network. The goal is to build an accurate model and deliver a detailed thermal performance evaluation: temperatures, duties, pinch points, approach temperatures, and any bottlenecks that appear once the network is integrated into the overall process flow. You may work in Aspen Plus or HYSYS for the main flowsheet and use Exchanger Design & Rating (EDR) or Energy Analyzer for the network itself—whichever produces the most reliable convergence and reporting. Please document every assumption (fluid properties, fouling factors, pressure drops) directly in the model notes so I can reproduce your results. Acceptance criteria • Complete Aspen file(s) with all units converged • Thermal perfor...

We have a electronic siren system which have some electronic components. There is a metal enclosure in which all the components are placed. The problem is that, the current system is temporary like a jugaad. We want to get the modular system designed so the goal is: 1. make every component plug and play 2. wirings and cables hidden inside and secure 3. make connections plug and play 4. Thermal dissipation so system cools down internally as there is no exit in the enclosure 5. make system compact and robust for coastal and extreme conditions. 6. Heat sinks and other ways we can make it temperature controlled. Let me also attach a basic requirements document also (AI generated according to our requirements) You are an expert so you can also suggest the implementation things.

I have the core concepts for a series of injection-mould inserts and cavities and now need them turned into fully detailed, manufacturing-ready designs that take full advantage of additive manufacturing. My single biggest focus is improving cooling efficiency, so every feature must revolve around high-performance conformal cooling channels built into stainless-steel inserts. You will translate my sketches and rough CAD into optimized 3D models, weave in lightweight lattice structures where they make sense, and run the engineering analysis required to prove shorter cycle times and higher overall productivity. Once the numbers look right, I will need clean STEP and STL files plus clear mold drawings that a service bureau or in-house metal AM team can run without further edits. Delivera...

Dispongo de una piscina cubierta climatizada de unos 510 m² que actualmente funciona con un deshumidificador de 20 kW. Quiero optimizar el sistema: conservar el equipo existente, pero añadir un recuperador de calor que renueve el aire interior y eleve la calidad ambiental sin disparar el consumo energético ni el nivel de ruido. Busco un especialista en HVAC que desarrolle una solución completa, incluyendo: • Auditoría del sistema actual: balance de humedad, caudales de aire y rendimiento del deshumidificador. • Cálculo de la tasa de renovación necesaria para la superficie y volumen de la piscina. • Selección o dimensionamiento del recuperador de calor y ventiladores, con fichas técnicas. • Esquema de i...

I’m developing a compact, aluminium-clad SMD PCB that will live directly on mains, so every detail must be right first time. The board sits on 1 mm aluminium with 25 µm copper, accepts 220-260 VAC and has to deliver a rock-solid 144 VDC at 300-350 mA. Power-factor must stay high thanks to a hybrid DOB topology, while the protection network must survive 6 kV surges and automatically cut in on both high- and low-voltage events. Everything must be RoHS-compliant. Because the board ultimately feeds a power-supply module, thermals and creepage/clearance are just as critical as the electrical design. I’m looking for a clean, production-ready package that lets me hand Gerbers straight to my fabricator and have parts placed with confidence. Deliverables • Complete schema...
