Senior Mechanical Design Expert | 24 Years HVAC / Heat Pump / Industrial Heat Pump Experience Turn your HVAC or heat pump product from concept to mass production — efficiently, reliably, and certification-ready. I have over 24 years of experience in mechanical structure design and product development in HVAC, heat pumps, and smart appliances. I have successfully led 200+ products from concept to mass production. My products are widely exported to Europe and North America, fully compliant with CE, UL, Keymark, TÜV, DVGW, UBA, KTW and other international standards, with strong experience in certification-oriented design. My Background Top-Tier Industry Experience: Worked at leading companies with mature product development systems: - Midea Group (Fortune Global 500) - A leading listed heat pump company - Chigo Air Conditioning (00449.HK) International Client Experience: Extensive experience working with global clients, providing customized product development: Carrier / Iceair / Thermondo / Kaisai / Olimpia / Notus / SKD Patents: - 1 National Priority Invention Patent - 12 Invention Patents - 100+ Utility Model Patents Core Expertise 1. HVAC / Heat Pump Structural Design - Full unit structure design (indoor / outdoor / integrated units) - Refrigeration system integration (compressor, heat exchangers, piping layout) - Noise reduction optimization (airflow vs noise balance) - Waterproofing, anti-vibration, piping stress & reliability design - Electrical enclosure safety & system integration 2. Industrial Heat Pump & HVAC Design - Industrial-grade heat pump system design - Industrial HVAC equipment (high reliability / long lifespan / harsh environments) - Custom non-standard equipment structure design 3. Manufacturing-Oriented Engineering (DFM / DFA) - Design for Manufacturing (DFM) - Design for Assembly (DFA) - Cost optimization - Mold feasibility analysis (plastic / sheet metal) Service Scope Heat Pump Products: Residential heat pumps (Monoblock / Split), modular systems, integrated water systems / hydraulic modules Air Conditioning & Light Commercial HVAC: Indoor / outdoor unit structure design, PTAC / window AC / portable AC, heat exchanger design (evaporator / condenser), electrical cabinet design Industrial & Custom Equipment: Industrial air conditioning, custom equipment structure design Additional Design Services: Sheet metal design, plastic part design, HVAC piping optimization, product upgrade & partial redesign Mold & Manufacturing Support: Mold design review (DFM), injection molding / sheet metal process optimization, supplier sourcing & factory coordination Cross-Functional Collaboration: Work with thermal engineers (refrigeration system optimization), work with electrical engineers (control system integration), support full system-level product development China-Based Engineering Support: Reliable supplier sourcing, on-site or remote production support, fast issue resolution during prototyping and mass production What I Need From You (Before Starting) To ensure an efficient project process, please provide as much as possible: 1. Basic Product Information: - System diagram / schematic - Sketch / concept / idea - Reference images or benchmark products 2. Certification & Market Requirements: - Target certifications (CE / UL / Keymark / TÜV, etc.) - Target market (Europe / North America, etc.) 3. Production Information: - Target production volume (prototype / small batch / mass production) - Whether you already have a factory or supply chain 4. Design & Manufacturing Preferences: - Material preference (plastic / sheet metal / hybrid) - Special requirements (cost target / appearance / size constraints, etc.) Even if you only have a rough idea or simple sketch, feel free to contact me. I can help you refine the concept and bring your product to life. My Commitment ✔ On-time delivery ✔ Design compliant with international standards (CE / UL, etc.) ✔ Production-ready, manufacturable design ✔ Free initial technical consultation ✔ Reliable and efficient communication
